4. Ethernet networks a switch is an effective way of eliminating problems of uplinking Fa st Ethernet hubs beyond the two repeater limit A switch can be used to split parts of the netw ork into different collision domains making it possible to expand your Fast Ethernet network be yond the 205 meter network diameter limit The switch supports both traditional 1 OMbps Ethern et and 100Mbps Fast Ethernet which is also ideal for bridging between the existing 10Mbps net works and the new 100Mbps networks 2 LAN Switching technology is a marked improvement over the previous generation of network br idges which were criticized by their higher latencies Routers have also been used to segment lo cal area networks But the router is typically expensive difficult to setup and maintenance inte nsive which makes it relatively impractical for the network Switch on the other hand is less ex pensive easier to setup and practically maintenance free which make it an ideal solution to tod ay s local area network congestion problems Features This high performance Switch was designed for a network environment where traffic and the nu mber of users increase continuously The Switch with their small desktop size was specifically design for small to middle workgroup s It provides immediate access to a rapidly growing network through a wide range of user reliab le functions The Switch is ideal for shared bandwidth 10Mbps or 100Mbps workgroups wi

8. rformance Fast Eth ernet solutions in the years to come 100Mbps Fast Ethernet is a new standard specified by the IEEE 802 3 LAN committee It is an extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100M bps while maintaining the CSMA CD Ethernet protocol Since the Switch is compatible with all 10Mbps Ethernet environments it provides a straightforward upgrade and takes advantage of th e existing investment in hardware software and personnel training Switching Technology Another approach to pushing beyond the limits of Ethernet technology is the development of swi tching technology A switch bridges and transmits Ethernet packets at the MAC address level of the Ethernet protocol among connected Ethernet or Fast Ethernet LAN segments Switching is a cost effective way of increasing the total network capacity available to users on a local area network A switch increases capacity and decreases network loading by dividing a loc al area network into different segments Each segment has its own bandwidth and it does not co mpete with others for network transmission capacity A switch acts as a high speed selective bridge between the individual segments The switch for wards traffic from origin segment to destination segment without interfering with any other seg ments By doing this the total network capacity is multiplied while still maintaining the same n etwork cabling and adapter cards For Fast
