The team removed all non-IP protocols on theABC’s Net II LAN. It was determined that the mixing of various protocols on the LAN turned out to be a major cause of network congestion. Switching to all IP protocol substantially reduced network congestion and decreased latency but unfortunately was very difficult to install. The system had issues with legacy applications and data sources that were not IP compatible. Substantial work had to be done to convert the seapplications and data sources to IP, and, in some cases, new software had to be installed to convert these applications.
Figure 2 illustrates a schematic view of ABC’s Net II. Note that in actuality there are more than three stores connected to the frame relay network,that there are two Cisco 7204 routers, and that there are more applications, applications servers,desktop machines, and phones than depicted in the diagram.
