Sample Applications for the CrossFire 8600 and the CrossFire 8605

The CrossFire 8600 and/or the CrossFire 8605 switch allows you to make incremental changes in your network to address both immediate and long-range performance challenges. For example, a Token-Ring LAN of 80 stations including 4 servers might experience performance problems as a result of increased traffic. As it is currently structured, the LAN looks like the one in Figure 8.

Figure 8. Typical LAN Segmentation

All of the stations are attached to access units located in a single wiring closet. You can install an switch in the same wiring closet and divide the LAN into 4 segments of 20 stations each. One access-unit port from each segment will be connected to a port on the switch via a patch cable. Finally, the four servers are removed from the access units to which they have been attached and their cables moved to four ports on the switch (as depicted in Figure 9).

Each group of 19 users attached to an access unit now shares a dedicated, 16 Mbps path to the server. Each server has a dedicated, 16 Mbps path upon which to service requests. The overall capacity of this solution is 64 Mbps; network capacity has increased fourfold.
