XTP versus TCP/IP in a UNIX/Streams environment

Abstract

Discusses whether XTP is a good replacement for TCP. The two are compared based on standard data transfers between UNIX systems using a Streams environment. The authors first modified the KRM implementation of XTP to port it to the Streams. Performance comparisons with TCP showed no significant differences. They modified XTP's acknowledgement strategy to reduce the number of control packets meant to acknowledge received data. It yielded an average 15% speedup. Beyond the protocol comparison, the authors also intend to analyze Streams environment support for communication system implementation.<>
