Examining The Network Simulations Of NS2 Information Technology Essay

Examining The Network Simulations Of NS2 Information Technology Essay NS2 is a Linux based tool to perform network simulations. NS2 is based on C++ and TCL programming Languages. TCL uses simple commands to define network configuration and C++ allows users to adjust protocol functionalities in detail and also to define new protocols. Our Project involves simulation of VoIP over two transport layer protocols UDP and SCTP. Installation of NS2: Installation of NS2 involves many steps. These Steps are: Checking for pre-requisites: Please make sure that you have installed the fedora 12 O.S with all packages and you are logged in as administrator. Downloading latest version of NS2: We first Downloaded NS2 v. 2.34 from: http://sourceforge.net/projects/nsnam/files/allinone/ns-allinone-2.34/ns-allinone-2.34.tar.gz/download Extracting the NS2 package: Extract the contents of .tar file in a directory and go into that directory. The following snapshot shows the extracted file against .tar file. Patching of SCTP module: Initially NS2 does not provide support to SCTP, so we have to download apply its patch before installation of NS2. The patch can be downloaded from http://pel.cis.udel.edu Now untar the patch in a directory and type the given command in terminal: patch -p0 Now we are ready to install NS2 with SCTP module. Installation of NS2 : We can either install NS2 by typing commands in the terminal. Or we can do this by simply double clicking the install file. The snapshot below shows the later. Now the installation has started. It would take some time to complete it. Configuring the installation path of NS2: The terminal will get get closed after installation of NS2. Now open terminal again and type: gedit ~/.bashrc to configure the path file Now edit this file as in the figure: Now save and close bash file and type following command in the terminal to tell your O.S about the path of NS2: source ~/.bashrc Confirming the installation of NS2: To confirm that NS2 is correctly installed, type ns in the terminal. The outlook of the terminal will be changed in this way: (Else it would print some filter of error in the terminal.) To revert to the normal mode type exit in the terminal. Running a simple code on NS2: NS2 executes .tcl file format. If you have followed all the previous steps, then you can execute a .tcl file by typing the following syntax in the terminal: ns [file name].tcl But make sure you are the directory where the .tcl file is present. e.g: Here we have a sample code script.tcl. In this code we are simulating a simple topology of two wired nodes. On typing ns script.tcl in the terminal, we get the following output: Handling the output trace file: On execution of .tcl code, two output files are generated. One is the .nam file with which we see the graphical simulation of our code. The other one is the .tr trace file, with which we can analyze the output of our simulation. The trace file looks like: It contains various parameters such as arrival time of packets, packet size transport agent etc. Using the trace file, we can get the graphical outputs to analyze the behavior of our simulation. To do this we need a graph drawing software such as xgraph or gnuplot. Here we are using gnuplot. But to draw a graph, we need to filter the trace file and get the coordinates out of which we can draw a graph. To filter a trace file, we write an awk script. Since we have to draw graphs for latency and throughput, therefore we will write one script for each type of graph. The awk script for latency is: #latency BEGIN { time1 = 0.0; time2 = 0.0; } { time2 = $2; if ($1==r) { printf(%f %fn, time1, time2) > latency; time1 += $2; } } END { print(Done); } And awk script for throughput is: #throughput BEGIN { node =1; time1 = 0.0; time2 = 0.0; num_packet=0; bytes_counter=0; } { time2 = $2; if (time2 time1 > 0.05) { thru = bytes_counter / (time2-time1); thru /= 1000000; printf(%f %fn, time2, thru) > throughput; time1 = $2; } if ($1==r) { bytes_counter += $6; num_packet++; } } END { print(Done); } Now type the following command in the terminal to filter the trace file: gawk file=[awk file name].awk [trace file name].tr The filtered file would be like this: Now weve to give a plot for which our graph is to be ploted. (i.e: weve to tell about the x and y coordinates) So we create a simple file in which we tell about these parameters. set title VoIP over UDP Latency! set grid set ylabel s set xlabel time plot latency w linespoints title voip throughput Now type gnuplot in the terminal to enter into gnuplot mode. Here type the command: load [x-y parameters file] (inner double quotes inclusive) And type exit to exit gnuplot Formation of VOIP Traffic over the Network: VoIP (Voice over IP) is simply the transmission of voice traffic over IP-based networks. The Internet Protocol (IP) was originally designed for data networking.   It is also referred to as IP  Telephony  or Internet Telephony. Simulating VOIP in NS2: VoIP is basically just UDP packets encapsulating RTP packets with the voice data inside, all you should need to do to simulate a VoIP stream is set the correct packet size and frequency that the packets are sent out and that would simulate a stream. In NS2 we will implement VOIP over UDP and SCTP protocols. We will implement VOIP using a simple two-node topology. For this we will do the following steps: create two .tcl files simulate VOIP traffic handle the trace files to draw graphs for latency and throughput for evaluation between the two protocols Simulation of VoIP over the network using UDP: Creating the tcl file:- First create a tcl file for Voip simulation over UDP protocol. Given below is the source code for our file voip_udp.tcl # start new simulation set ns [new Simulator] # setup tracing/nam set tr [open voip.tr w] set nf [open voip.nam w] $ns trace-all $tr $ns namtrace-all $nf # finish function, close all trace files and open up nam proc finish {} { global ns nf tr $ns flush-trace close $nf close $tr exec nam voip.nam exit 0 } ### creating nodes set node0 [$ns node] $node0 label Voice 1 $node0 color red set node1 [$ns node] $node1 label Voice 2 $node1 color blue # creating duplex-link $ns duplex-link $node0 $node1 256Kb 50ms DropTail $ns duplex-link-op $node0 $node1 orient right # setup colors $ns color 1 Yellow $ns color 2 Green ## 2-way VoIP connection #Create a UDP agent and attach it to node0 set udp0 [new Agent/UDP] $ns attach-agent $node0 $udp0 # set udp0 flowid to 1 $udp0 set fid_ 1 # Create a CBR traffic source and attach it to udp0 set cbr0 [new Application/Traffic/CBR] $cbr0 set packetSize_ 128 $cbr0 set interval_ 0.020 # set traffic class to 1 $cbr0 set class_ 1 $cbr0 attach-agent $udp0 # Create a Null sink to receive UDP set sinknode1 [new Agent/LossMonitor] $ns attach-agent $node1 $sinknode1 # Connect the UDP traffic source to Null sink $ns connect $udp0 $sinknode1 set udp1 [new Agent/UDP] $ns attach-agent $node1 $udp1 $udp1 set fid_ 2 set cbr1 [new Application/Traffic/CBR] $cbr1 set packetSize_ 128 $cbr1 set interval_ 0.020 $cbr1 set class_ 2 $cbr1 attach-agent $udp1 set sinknode0 [new Agent/LossMonitor] $ns attach-agent $node0 $sinknode0 $ns connect $udp1 $sinknode0 # end of voice simulation setup # start up traffic $ns at 0.1 $cbr0 start $ns at 0.1 $cbr1 start $ns at 10.0 $cbr0 stop $ns at 10.0 $cbr1 stop $ns at 10.5 finish # run the simulation $ns run Simulate VOIP traffic: Now type the following command in the terminal to view simulation of VOIP over UDP: ns voip_udp.tcl The output is: Performance of SCTP: Now we draw the graphs with gnuplot using above mentioned steps. The performance is evaluated on the basis of latency, throughput and capacity. The capacity can be evaluated with the help of latency and throughput. Latency: Throughput: Simulation of VoIP over the network using SCTP: Creating the tcl file:- First create a tcl file for Voip simulation over UDP protocol. Given below is the source code for our file voip_sctp.tcl # start new simulation set ns [new Simulator] # setup tracing/nam set tr [open voip.tr w] set nf [open voip.nam w] $ns trace-all $tr $ns namtrace-all $nf # finish function, close all trace files and open up nam proc finish {} { global ns nf tr $ns flush-trace close $nf close $tr exec nam voip.nam exit 0 } ### creating nodes set n0 [$ns node] $n0 label Voice 1 $n0 color red set n1 [$ns node] $n1 label Voice 2 $n1 color blue # creating duplex-link $ns duplex-link $n0 $n1 256Kb 50ms DropTail $ns duplex-link-op $n0 $n1 orient right # setup colors $ns color 1 Yellow $ns color 2 Green ## 2-way VoIP connection #Create a UDP agent and attach it to n0 set sctp0 [new Agent/SCTP] $ns attach-agent $n0 $sctp0 $sctp0 set fid_ 1 set cbr0 [new Application/Traffic/CBR] $cbr0 set packetSize_ 128 $cbr0 set interval_ 0.020 # set traffic class to 1 $cbr0 set class_ 1 $cbr0 attach-agent $sctp0 # Create a Null sink to receive Data set sinknode1 [new Agent/LossMonitor] $ns attach-agent $n1 $sinknode1 set sctp1 [new Agent/SCTP] $ns attach-agent $n1 $sctp1 $sctp1 set fid_ 2 set cbr1 [new Application/Traffic/CBR] $cbr1 set packetSize_ 128 $cbr1 set interval_ 0.020 $cbr1 set class_ 2 $cbr1 attach-agent $sctp1 set sinknode0 [new Agent/LossMonitor] $ns attach-agent $n0 $sinknode0 $ns connect $sctp0 $sctp1 $ns at 0.1 $cbr0 start $ns at 0.1 $cbr1 start # stop up traffic $ns at 10.0 $cbr0 stop $ns at 10.0 $cbr1 stop # finish simulation $ns at 10.5 finish # run the simulation $ns run Simulate VOIP traffic: Now type the following command in the terminal to view simulation of VOIP over UDP: ns voip_sctp.tcl The output is: Performance of SCTP: Now we draw the graphs with gnuplot using above mentioned steps. The performance is evaluated on the basis of latency, throughput and capacity. The capacity can be evaluated with the help of latency and throughput. Latency: Throughput: Difference between SCTP and UDP: SCTP: SCTP Stands for Stream Control Transmission Protocol. It is a Transport Layer protocol. It is a connection-oriented protocol similar to TCP, but provides facilities such as multi-streaming and multi-homing for better performance and redundancy. It is used in Unix-like operating systems. UDP: UDP stands for User Datagram Protocol. It is a minimal message-oriented transport layer protocol. It enables two hosts to connect and send short messages to one another. Unlike Transmission Control Protocol (TCP), it does not guarantee that data is received or that it is received in the order in which it was sent. Comparison between SCTP and UDP: Message Orientation: In SCTP, message boundaries are preserved. If an application sends a 100-byte message, the peer application will receive all 100 bytes in a single read: no more, no less. UDP provides a message-oriented service, but without SCTPs reliability. Un-Ordered Service: In addition to ordered message service (and parallel ordered service discussed above), SCTP offers the reliable delivery of messages with no order constraints. UDP provides unordered service, but again without SCTPs reliability. Unordered reliable delivery will be useful for many applications, in particular disk over LAN services (iSCSI, RDMA, etc.) where the application already provides ordering. Stronger checksum: SCTP uses a 32-bit end-to-end checksum proven to be mathematically stronger than the 16-bit ones-complement sum used by UDP. SCTPs better checksum provides stronger verification that a message passes end-to-end without bit errors going undetected. These were some of the differences between SCTP and UDP. A tabulated contrast between the two protocols is given below: Services/Features SCTP UDP Connection-oriented yes no Full duplex yes yes Reliable data transfer yes no Partial-reliable data transfer optional no Ordered data delivery yes no Unordered data delivery yes yes Flow control yes no Congestion control yes no ECN capable yes no Selective ACKs yes no Preservation of message boundaries yes yes Path MTU discovery yes no Application PDU fragmentation yes no Application PDU bundling yes no Multistreaming yes no Multihoming yes no Protection against SYN flooding attacks yes n/a Allows half-closed connections no n/a Reachability check yes no Psuedo-header for checksum no (uses vtags) yes Time wait state for vtags n/a SCTP vs. UDP Latency: From the graphs of latency we conclude that latency is slightly higher in UDP. In real practice, latency in UDP is much higher than in SCTP. Practically, the latency in UDP is about 15% more than SCTP. Throughput: From the graphs of throughput we see that UDP shows a constant but less throughput while SCTP shows continuous fluctuations in its graph. But overall SCTP has a higher throughput than UDP. In real practice, throughput in SCTP is about 15% more than in UDP. Capacity: By observing the graphs of throughput, we conclude the SCTP can support more capacity than UDP. UDP will loose its performance at higher data rates. Conclusion: From the above statistics, we conclude that SCTP is better than UDP in terms of latency, throughput and capacity. Therefore there is no doubt in the fact that that SCTP is going to be the future of VOIP and many other network technologies. But since this technology is under the process of evolution so it may take some time for it to replace the older technologies like UDP and TCP etc. Refrences: http://yonghoon.livejournal.com/4799.html http://www.isoc.org/briefings/017/index.shtml http://www.google.com/dictionary?source=dict-chrome-exsl=entl=enq=sctp http://www.google.com/dictionary?langpair=en|enq=udphl=enaq=f http://mailman.isi.edu/pipermail/ns-users/2006-August/056723.html http://books.google.com.pk/books?id=bF3L7g1u_mQCpg=PA189lpg=PA189dq=udp+vs+sctp+latency+throughputsource=blots=zdb5JeCsMfsig=PPt8c4nvtcrIJcXr5eKBIe_GbkQhl=enei=XhIgTYCeLs-z8QO8_KS8BQsa=Xoi=book_resultct=resultresnum=2ved=0CB4Q6AEwAQ#v=onepageqf=true

Patterns for College Writing Essay

  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   I spent the night before contemplating how I was going to get out of school on Thursday.   There was a social studies test I didn’t study for and I just could not bare another day of dodge ball.   On the morning of September 11, 2001 I woke up â€Å"sick†.   I pleaded with my mother, and took a fake trip to the bathroom because I was going to â€Å"vomit†.   Finally, I was allowed to stay home.   At 6:00 am,   I was ordered to go back to sleep and I did.   I looked forward to my day alone as I lingered between sleeping and waking pondering how I was going to fill my day with – snacks, computer games, and loud music. September 11, 2001 began as a childhood scheme and it ended with me growing up.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   I dozed much of the morning and awoke to the sound of my brother’s radio alarm going off.   It was Thursday and he shouldn’t be home.   I pouted as I slowly got out of bed to see if I was truly alone.   I walked down the hall and stopped briefly at the bathroom and then into my brother’s room.   He was gone, and the alarm had been set wrong.   The people on the radio droned on and on.   I wandered around the room hoping to find a magazine that I let brat borrow weeks ago. As I was on my knees peaking under the bed the words on the radio became clear.   I heard the word â€Å"terrorists† and the fragments of statements like â€Å"hundreds died this morning when†.   Then, I could only hear my heart beat in my ears.  Ã‚   I got to my feet and for the first time since being a child, I felt real panic. The sort of panic you feel when you are four and you have wandered away from your parents.   Once I caught my breath I made my way to the family room, frantically searching for the remote.   I turned on the television to MSNBC and the first image I saw was a man jumping from a broken window of one of the twin towers.   I was baffled and this would be the image that would haunt my dreams, my waking memories, and what it meant to be an American.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   I heard the details over and over again.   The errorists had hijacked three planes and deliberately crashed them into the Pentagon and the Twin Towers.   The video clips played again and again on the news.   The smoke filled horizons around the crumbling buildings.   Paper was flying everywhere and the sound of heart broken people wailing in the background filled the screen.   I stared and there were moments where I thought it might be a movie and all I had to do was change the channel.   The phone must of rang a dozen times before I answered it   It was my mother on the other end, asking me again and again if I was ok.  Ã‚   She told me she would be home soon.   I waited, though I did not know for what, and watched.   The Towers were now in flames as the reporters spoke in what seem like whispers.   Their words almost silenced but the sound of a city slowly dying.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   I remember hearing the back door open and close, and my mother sitting down next to me.   It was the first time since I was a child that she held my hand and I let her.   Stunned, we sat together as the news reported that at 8:40 am the terrorists crashed planes into the World Trade Center.   It was hard to comprehend.   My mother cried and I cried too except on the inside.   I watched her body shake as she twisted her ring around and around her finger.   My mother, who could out talk just about everyone we knew, was speechless.   It was then that I understood – she was scared too.   I hugged my mother and told her everything would be all right.   I told her we would be safe and that we had each other.   I made us coffee and we spent much of the afternoon talking about what happened, what could happen, and what we would do.   What we spoke about most was â€Å"why†.   Why did the terrorists hate Americ a?   Why did people kill other people for no apparent reason?   Comforting my   mother in the ways she had comforted me for so many years, came unexpectedly to me.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Over the next few months we followed the story as did the world.   I can remember President Bush attempting to comfort the United States and telling us America would be going to war for reasons that weren’t clear to me then and certainly aren’t clear to me now.   Suddenly video games and staying home from school just weren’t important anymore.   Dodge ball did not seem so bad.   Instead of hiding from my parents I sought them out, wanting to discuss my day and theirs together.   I do not believe what does not kill us makes us stronger.   However, I think that what does not kill us makes truly value what we have in life and to realize how much our family and friends mean to us.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   My family and I became very active in volunteer activities especially with the Red Cross.   We donated bottled water, clothing, blankets, and food.   Our community held local charity events to raise money for the victims of September 11 including those firemen and police officers who gave their lives in the fires of 9/11.   It was the first time I or my family had ever become involved in activities that did not directly benefits ourselves.   The sense of community and patriotism that was built in the months following the terrorists attacks still exists with me today.   We now volunteer regularly as a family for a number of charities.   Through the destruction of the Twin Towers, I finally understood my place and role in society.   Not as a bystander but an active and willing participant.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   On September 11, 2001 many people lost their lives and I gained my independence from childhood fantasies.   Before that Thursday in September, I never thought about life and death.   I never considered the consequences of war and the denial of freedoms.   Now that I am older, I realize that September 11, 2001 was not just pivotal point for me but America itself.   Not since Pearl Harbor had the United States been unexpectedly attacked on it’s own land.  Ã‚   Just as families pulled together so did the United States as a whole.  Ã‚   We cried together and we healed together.  Ã‚   To actually witness the attacks was life changing but to be part of the healing process was life affirming.

Seven Personal Qualities Found in a Good Leader

How often have you heard the comment, â€Å"He or she is a born leader?† There are certain characteristics found in some people that seem to naturally put them in a position where they're looked up to as a leader. Whether in fact a person is born a leader or develops skills and abilities to become a leader is open for debate. There are some clear characteristics that are found in good leaders. These qualities can be developed or may be naturally part of their personality. Let us explore them further. 1. A good leader has an exemplary character. It is of utmost importance that a leader is trustworthy to lead others. A leader needs to be trusted and be known to live their life with honestly and integrity. A good leader â€Å"walks the talk† and in doing so earns the right to have responsibility for others. True authority is born from respect for the good character and trustworthiness of the person who leads. 2. A good leader is enthusiastic about their work or cause and also about their role as leader. People will respond more openly to a person of passion and dedication. Leaders need to be able to be a source of inspiration, and be a motivator towards the required action or cause. Although the responsibilities and roles of a leader may be different, the leader needs to be seen to be part of the team working towards the goal. This kind of leader will not be afraid to roll up their sleeves and get dirty. 3. A good leader is confident. In order to lead and set direction a leader needs to appear confident as a person and in the leadership role. Such a person inspires confidence in others and draws out the trust and best efforts of the team to complete the task well. A leader who conveys confidence towards the proposed objective inspires the best effort from team members. 4. A leader also needs to function in an orderly and purposeful manner in situations of uncertainty. People look to the leader during times of uncertainty and unfamiliarity and find reassurance and security when the leader portrays confidence and a positive demeanor. 5. Good leaders are tolerant of ambiguity and remain calm, composed and steadfast to the main purpose. Storms, emotions, and crises come and go and a good leader takes these as part of the journey and keeps a cool head. 6. A good leader, as well as keeping the main goal in focus, is able to think analytically. Not only does a good leader view a situation as a whole, but is able to break it down into sub parts for closer inspection. While keeping the goal in view, a good leader can break it down into manageable steps and make progress towards it. 7. A good leader is committed to excellence. Second best does not lead to success. The good leader not only maintains high standards, but also is proactive in raising the bar in order to achieve excellence in all areas. These seven personal characteristics are foundational to good leadership. Some characteristics may be more naturally present in the personality of a leader. However, each of these characteristics can also be developed and strengthened. A good leader whether they naturally possess these qualities or not, will be diligent to consistently develop and strengthen them in their leadership role.

Causes of World War I Germany Essay - 1602 Words

World War I was a war between the allies, which included Russia, France, Serbia, and Great Britain, against the central powers of Europe; Germany and Austria. When war broke out between Austria and Serbia in 1914, the alliance system drew the other European countries into the war; consequently the rest of the world was brought into the conflict. In the early twentieth century, Germany was witnessing a prospering economy alongside an increased sense of national pride. With the growing economy, Germany began to make progress in the Arms Race and in the development of their navy. Under the control of William II, Germany made a series of unlawful decisions that added to the animosity between European superpowers. With the introduction of†¦show more content†¦As stated by Suzanne Karpilovsky, â€Å"The standing armies of France and Germany doubled in size between 1870 and 1914.† (Karpilovsky, Fogel and Kobelt). In this way, Germany’s rapidly growing military expendi ture made other European countries feel insecure about their safety. Great Britain had its own insecurities regarding Germany; in particular Great Britain’s â€Å"Balance of Power† policy was being disrupted as Germany’s military strength was making Germany the most powerful country in Europe. This led to increased feelings of tension between Germany and other European powers; as Henry Kissinger stated, â€Å"Germany became the strongest and as such proved disquieting to its neighbors.† (Kissinger 169). This is why Germany’s immense progression in the arms race during the early 20th century can be seen as a factor in causing World War I. During the early 20th century, Germany was well on its way to being one of the most powerful nations in the world.

The First Act Of Hamlet By William Shakespeare - 1447 Words

Hamlet Throughout the first act of Hamlet, by William Shakespeare, clothing imagery is used to illustrate the common theme of â€Å"is versus seems.† The clothing references made with Laertes, son of Polonius, Gertrude, the queen of Denmark, and Hamlet, the protagonist of the play, come to either reflect the character’s true feelings, or highlight the differences between what the character feels and what emotion they display. Before leaving to France, Polonius, counselor to the king, advises his son Laertes to buy fine, impressive clothing because clothing often represents the man who is wearing them and by donning impressive clothing, it makes the wearer seem more impressive than he may actually be. Additionally, the same shoes that Gertrude wears whenâ€Å"lovingly† following Hamlet Sr., the former king of Denmark, are worn again to her wedding with Claudius. The shoes highlight Gertrude’s true feelings toward Hamlet Sr. because by wearing them with both Haml et Sr. and Claudius, she displays her insensitivity towards Hamlet Sr. and her blunt acceptance his death. In contrast to Laertes and Gertrude, Hamlet wears black clothes to mourn his father’s death, not just because he should seem like he is upset, as is suggested by Gertrude, but rather because Hamlet actually is, wholeheartedly, mourning over the loss of his father. While many characters in the play mourned for the late King Hamlet superficially, Hamlet truly feels upset and his clothing reflect this sadness.

Tough Choices No Way Out - 910 Words

In Angels in America many characters hide who they are and others flaunt it freely. Kushner uses characters that are ashamed of themselves, and characters that are shunned by society to display that once you are labeled as different you have tough choices to make. In Angels in America characters are accepted,through hiding themselves,or are shunned,for displaying their true natures, but the effects of both behaviours on the these character mentalities are the same. Joe is ashamed of his sexuality. He suffers internally and despite putting on a facade, fails to live a happy life. His internal struggles are manifested in his most vulnerable moments, for example, when arguing with his wife.

Roy continues to hide who he is,out of fear, and in the process he eliminates his chances of fighting off death.In conjunction, he sees the world as something that is working against him. When he says, â€Å" I see the universe,Joe, as a kind of sandstorm in outer space with winds of mega-hurricane velocity, but instead of grains of sand it’s shards and splinters of glass†(1:2,13), Roy is expressing his feelings that who he really is would not be accepted by â€Å"the universe† and therefore he must pretend to be someone else. He is scared the storm will consume him, wear and cut at him, just for being what he is. Roy is afraid; he is ruled by fear and his life revolves around gaining power over his situation in order to quell his fear.

Mudslinging free essay sample

Effects of Negative Political Ad Campaigns MKT 650 – Dr. Kunz Jeremy Pflug Merriam-Webster Dictionary defines a â€Å"mudslinger† as one that uses offensive epithets and invective especially against a political opponent. (Merriam-Webster, 2010) Mudslinging has many sources that all stake claim to being its origin. William Safire states that the word derived from some Ancient Latin advice, â€Å"Fortiter calumniari, aliquia adhaerebit,† which is translated into â€Å"Throw plenty of dirt and some of it will be sure to stick,† as seen in the â€Å"The Barber of Seville† in 1775. Safire, 1993) Negative advertisement political campaigns began in the United States all the way back to the time of our founding fathers. In the election of 1800 between John Adams and Thomas Jefferson, Adams was accused of being a monarchist who wanted to move the country to a monarchy under Britain and France, which at the time of the election was a very sensitive subject co nsidering the Revolutionary War was still fresh in the minds of Americans. Thomas Jefferson was accused of being a misogynist and of having an affair with a black slave; which later turned out to be true. Mark, 2007) Thomas Jefferson eventually won this election over John Adams and Aaron Burr (who became the Vice President to Jefferson after the each has the same amount of Electoral Votes and the House of Representatives chose Jefferson as the President of the United States. ) Negative political advertisements began on the television during the 1964 election, pitting President Lyndon B. Johnson and the Republican Senator Barry M. Goldwater. This advertisement only lasted 60 seconds and was only aired one time but its effectiveness set a precedent for many years to come. The â€Å"Daisy Ad† was widely criticized for being over the top and extreme. This 60-second spot featured a little girl picking petals off of a daisy in a field and counting out of sequence just before a voiceover begins a countdown, then follows that by a very strategic image of a nuclear explosion. President Lyndon B. Johnson followed this imagery with these words, These are the stakes – to make a world in which all of Gods children can live, or to go into the dark. We must either love each other, or we must die. (Jones, 2007) This set forth the beginning of advertisements whose sole purpose was to damage an opponent’s view in the public eye. Mark Zuckerberg, states that â€Å"In the last hundred years†¦ the way to advertise was to get into the mass media and push your content†¦Ã¢â‚¬  (Holzner, 2009) and candidates have been doing so for many years and with the advancements of technology, candidates can reach people in a one on one setting without every actually meeting that person. Tony Schwartz stated that political parties used to be the means of communication from the candidate to the people. Political would go on campaign trails and bring news of why their candidate was what was best for the United States of America. These days of the past are over and the new political parties are in the forms of ABC, NBC and CBS. (Kaid, 1993) In 2009, The Fox News Channel was the number one rated cable news network for 86 consecutive months and I believe this streak is still intact today. (Guthrie, 2009) Americans rely on television news stations as their main source of information along with the internet. It is almost unheard of a television channel not having their own website that updates the same information that they reveal in their programs and then update then instantly to their viewers. This relay of information brings many new challenges for political leaders and their campaign directors as they seek out inventive ways to attractive consumers†¦ aka the people of the United States. Mudslinging has many effects and yet the underlying question is whether or not these campaign advertisements are doing any real justice for the political campaign trail or are they just damaging both candidates What is the true impact that a negative advertisement has on a campaign? Does it truly impact the people of the United States and pander to the emotions of each individual person or do these malicious attacks on one another take away from the true meaning of the campaign and turn people away from the voting because they do not know which person is of the lesser evil†¦ One hypothesis is called the Stimulation Hypothesis and it suggests that people will turn out to vote once they experience some sort of difficulty or unfavorable change that will affect their way of living. Southwell, 1988) This negative attention draws people to the polls in order and creates a larger number of registered voters than in the previous election. Negative advertisement political campaigns have become a â€Å"guilty pleasure† of Americans. (Martin, 2004) It is like watching a video of a horrific event such as a car accident or an engulfing tornado whose destruction hurts many people however no m atter how destructing the nature of event is our society cannot pry ourselves away from watching the event. These negative advertisements have the affect of a sit-com and the people cannot wait to see what is next. The thought process behind the stimulation process is that negative advertising is equal or more informative than positive advertising. This information in turn acquires more interest. These interested voters are likely to vote and finally this will increase turn out in response to exposure to this negative advertising. Zaller, 1992) This hypothesis was analyzed in the 1996 elections and based on an article Goldstein and Freedman, they argued that there is good reason to expect vigorous campaign attacks to stimulate voters: by engaging voters, by raising interest, and by communicating the notion that something important is at stake in the outcome of an election, negative ads (whether they are contrast ads or pure negative spots) should be more likely to stimulate than depress voter turnout. 2002) A spinoff of the stimulation hypothesis is the Differential Effects which play off the emotions of the people of the United States. These differential effects are advertisements that affect the turnout if the advertisement addresses an issue of political concern to the voter. (Clinton amp; Lapinski, 2004) The differential effects like the mobilizations hypothesis occur when people are getting information from candidates that affect them. In 2008, Sen. Barack Obama played the people of the United States by encouraging â€Å"change† as this became the backbone of his campaign. The more that Sen. McCain negatively ran advertisements against the Sen. Obama the more imbedded these ideals of change became to the people of the U. S. The emotion that change was needed in order for not only ourselves to become successful but that the future of our children’s lives were at stake was the effect differential effect that Sen. Obama had over Sen. McCain. The Demobilization Hypothesis counters the stimulation hypothesis and argues that there is a relationship that exists between the negatively correlated trending variables of voter turnout and campaign negativity. Ansolabehere and Iyengar 1995) With the demobilization hypothesis, negative advertising is believed to have a destructive effect on the voting â€Å"Independents† since attack campaigns â€Å"heighten the partisan flavor of political discourse† and drive â€Å"the Independent voter from the active electorate† by breeding â€Å"distrust of the electoral process and pessimism about the value of an individual’s own voice. † (1995) During the 1988 Presidential Campaign, a Newsweek article said, â€Å"Voters are fed up and turned off by a hail of mudslinging. But it’s likely to get worse as both sides step up their attack-man ads. † (Garramone, 1990) The people of the United States based on this hypothesis want to see candidates for who they really are; their moral background, what their views on the issues really are, how they plan to achieve the goals and promises that they make and not how the candidate that they running against isn’t telling the truth about his plan or voting history. The negative advertisements are seemingly a he said/she said playground tiff and the voters are tired of wading through all the mudslinging to get down to the actual factual information. Research has show that the transfer of attitudes recursively (TAR) effects have shown that communicators often acquire the valence they ascribe to others, such that people who communicate positive attitudes about others acquire a positive valence whereas people who communicate negative attitudes about others acquire a negative valence. Carraro, 2009) These provide more evidence that people do not appreciate slander of another person. People want to hear the truth about the candidate themselves and not necessarily what that other candidate has done negatively. Another negative finding is that these political candidates are pandering to huge businesses and accepting campaign funding in order to have a say in the agenda of that candidate. In the 2008 elections, total spending on political advertising th is year by candidates and interest groups reached at least $2. billion, the highest amount ever in a presidential election year. About 2 billion of that money was allocated towards television advertisements. Many of us have seen political campaign advertisements that in the end an over voice states, â€Å"Paid for by†¦Ã¢â‚¬  Walter Shapiro of Time Magazine states, â€Å"Negative advertisement spots are pandering to large contributors†¦ â€Å"They† are largely responsible for public cynicism toward politics. That is why it may be wiser to target the attack ads themselves rather than the brutal cost pressures that make them necessary. (Mayer, 1996) Shapiro makes a very valuable assessment of the opinion that the public has towards negative advertisements because they understand where the money is coming from. The public views this as a political candidate is accepting money for a bill to be passed or an issue to be brought before the government that has a direct im pact of the company that gave the contribution. I believe that there is a direct effect on people based on their own personality. I feel that people will chose to hear what they want about a candidate and become educated about that persona and then make a decision. There is evidence that negative advertisements in these political campaigns provide boosts for the candidate that makes the claim about the other however there is too much evidence that can refute this claim and say that because of the negative ad, this candidate has not only hurt the candidate that they are running against but has also damaged their own character and integrity because they need this negativity to win over the people of the United States. Robert Collier said, â€Å"There is little difference in people, but that little difference makes a big difference. That little difference is attitude. The big difference is whether it is positive or negative. † With this quote, I believe the entire argument is for either side is summed up. They are both correct and the effects of the advertisements directly correlate to what type of person sees the advertisement. References Ansolabehere, Stephen, and Shanto Iyengar.
