Htpnet: a New Transport Protocol for High-speed Networks

The quantum increase in transmission speed of optical bre networks has created a bottleneck in transport protocol processing at host systems In this paper we present a new transport protocol system HTPNET that is designed to overcome this protocol processing bottleneck HTPNET is based on a highly parallel architecture and is designed to exploit the evolving char acteristics of high speed networks HTPNET uses an out of band signalling system based upon transmitter paced periodic exchanges of state information between end systems This mechanism exhibits several attractive properties which have been demonstrated to perform e ciently in a high speed envi ronment with high bandwidth delay product A prototype implementation of HTPNET has been constructed from a network of T transputers The results obtained from this implementation are presented these demonstrate the advantages of exploiting a parallel architecture for protocol processing E mail chants spectrum cs unsw oz au iango spectrum cs unsw oz au
