This project is to construct the model of WAN for a company on along the east coast. This company has offices in Atlanta, Philadelphia, New York and Boston. Headquarter of theoffice is located Washington D.C. which is the central network. As every office uses phone lines to connect to each other, so there is delay occur due to the unrelated traffic on the lines.
Due to the problem, this company need to determine how the background traffic is affecting the FTP traffic on the network.
So, this analysis is to compare the FTP performance on the network under two scenarios. First is network without background traffic and, second is the scenario with background traffic.
This WAN network contains 5 majors nodes which represent 5 location along the east coast. The network is connected by 10 Base-T.
Inside each node, it contains subnet LAN network and main router of each location, except in Washington D.C., which is headquarter, besides from LAN network and router, there is one main server located in the location as well
However, even though there are detail of subnet LAN network in each location, because this analysis is focus on WAN, so it is not necessary to consider detail in each location. Each office location will be considered as one node. So there are 5 nodes considered in this analysis.
Point to Point utilization Analysis
This first analysis focuses on the usage of network that compares 2 scenarios as mention earlier. The red graph show usage rate of network when there is no other back load in the network. And blue graph represent otherwise. The result shows a distinctive different between these 2 scenarios. With back load, average utilization rate goes up to almost 11 at the 25th minute. On the other hand, without back load, the utilization rate is relatively low. So, from this simulation, back load shows a distinctive affect on the overall WAN.
