High Performance Transports: HTPNET, TCP/IP, XTP, TP++ and RTP
By Zahid Hossain, Ohio State University
Abstract
The high transmission speed of optical networks has resulted in shifting of communication bottlenecks from the transmission media to the host processing system, especially the transport protocol processing at the end systems. New protocols, such as XTP, HTPNET, RTP, have been proposed by researchers to meet the requirements of high speed networks. TCP/IP, which has been very successful as a transport protocol for the last twenty years, is also adapting itself in high-speed network.
