2 I NTRODUCTION This chapter describe s the features of the DES-1024D and some background informati on about Ethernet/ Fast Ethernet s witching tec hnology. Fast Ethernet Technology Ethernet, along with its speedier coun terpart Fast Ethernet, is the most popular netw orking standa rd in use today. 100BaseT Fast Et hernet is an extension of the 10B[...]

3 Switching Technology Switching is a cost-effective way of i ncreasing the total network capacity available to users on a L AN. If an Et hernet netw ork begins t o display symptom s of congestio n, low thr oughput, sl ow response t imes, and high rate s of collision, installing a switch to a network can preserve much or all of the existing network[...]

4 Switching L AN technolo gy is a marked im provement ove r the pre vious generation of netw ork hubs and bridges, w hich were characteri zed by higher latencies. Rout ers have also been used to se gment local area netw orks, but the cost of a router, the setup and maint enance re quired, ma ke routers relatively impractical. Today switches are an [...]
