摘　　要：TOP运输层协议是OSI(国际标准化组织)标准协议的子集.它选择适当的参数和选项以满足技术与办公自动化应用的需要.本文指出了TOP运输层协议选择中存在的问题和解决方法,讨论了几个在UNIX系统上实现TOP的重要问题:采用连接上下文切换技术来控制运输连接的并发性;使用集成化操作技术管理协议占用的资源;选择依赖于重发时钟的滑动窗口策略来提高网络吞吐量.最后,给出了协议调试及运行情况监测的方法.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
