The Design and Implementation of TOP Transport Protocol in UNIX Kernel

TOP is a subset of OSI protocols with option and parameter selection reflecting the needs of technique and office automation application.Problems in the transport layer of TOP and their solution are pointed out.Several critical issues for implementing TOP on UNIX are discussed with details.Connection context switching technique is developed to control transport connection concurrency.Integrated operation techni-que is developed to manipulate resources used by protocol.Sliding window strategy depending on the retransmit timer is used to enhance throughput of network.Debugging and monitoring methods are presented
