Design and Performance Evaluation of a High Speed Transport Protocol

Abstract

Transport protocols that were designed for network today are not adequate for high speed networks of the future due to the increase in network bandwidth relative to the speeds of the processor components. As a result, 100 Mb/s-lGb/s high speed networks are now available but however at the top of transport layer, 10 Mb/s or even less is only achievable with current protocols. This increases the demand on new architectures and protocols to be designed and implemented. In this paper we suggest a model for the transport protocol and implement the idea of exchanging the complete state information between the transmitter and receiver periodically. This idea was introduced by AT&T. We implement two versions of the simulator, the first version implements the positive acknowledgment method, the second version implements the new idea. Both simulators implement the same proposed model for the transport protocol. The simulation results show that the new idea makes a big enhancement on the performance in the high speed environment.
