SIMULTATION OF GIGABIT ETHERNET AND MEASURING ITS PERFORMANCE AGAINST FAST ETHERNET

Abstract

The accelerating growth of LAN traffic is pushing network administrators to look for even higher-speed backbone network technology, which can be compatible with existing Ethernet installation. Gigabit Ethernet is one such higher speed network technology. . Gigabit Ethernet uses the same frame format, and functions as its 10Mbps and 100Mbps precursors. It offers1000Mbps bandwidth and uses the same CSMA/CD protocol. This works evaluates the performance of Gigabit Ethernet and also presents a comparative study of Gigabit Ethernet against Fast Ethernet. It is shown that half-duplex Gigabit Ethernet achieves over 70% throughput with a 100% offered load. It is also shown that as packet size increases, the performance of Gigabit Ethernet Exceeds the performance of Fast Ethernet. 7
