Additional Description

Abstract

It has been twenty years since Ethernet emerged as network technology. During these years the processing speeds of the attached hosts has increased by several orders of magnitude. The initial 10Mbps Ethernet can be easily saturated by one high performance desktop workstation. With considerable number of high performance desktop workstation [sic] even Fast Ethernet which offers a bandwidth of 100Mbps is showing signs of congestion. Hence the need for much faster networks.

As higher bandwidths become available the minimum packet size to be transmitted over the physical medium also increases. Networks with high rate of small packets are slowed down, as they have to pad each packet to bring it up to the minimum size Ethernet can transmit. By eliminating the requirement of the minimum packet size to be twice the propogation delay the effective throughput of the network consisting of small packets can be improved. The presented protocol eliminates minimum packet size requirement and thus reduces the need of padding for small packets. This in effect increases the effective throughput for small packets. The protocol behaves same way the standard Ethernet would behave for packets, which are larger than round trip delay. By permitting transmission of many small packets simultaneously we increase the effective throughput and reduce the delays associated. The binary exponential back off algorithm used in standard Ethernet is modified to reduce delays and to eliminate the capture effect of the algorithm. Equal priority is given to all stations, backlogged or not.

The mentioned protocol is simulated to observe the influence of the various packet sizes on the network. Simulation results show that by implementing the protocol higher effective throughput can achieved [sic] on networks with a large percentage of small packets. The results are very similar to that of a standard Ethernet for larger packets. In all cases the presented protocol performed no worse than the standard Ethernet.
