摘　　要：针对IPv6与IPv4协议不完全兼容,为了保证TCP包在IPv4/IPv6网络互通时的传输正确性,通过对TCP滑动窗口机制的分析,设计了一套新的会话控制列表结构来记录TCP包在进行转换时候序号发生的变化,并且在转换网关处理程序中加入对该表的控制,保证了转换中的数据包序号的正确性,同时也解决了重传包的检测和处理问题.In view of the partial compatibility of IPv6 and IPv4 protocol, how to ensure TCP packet transmission accuracy in the process of IPv4/IPv6 network intercommunication is something that merits our special attention. Based on the analysis of the mechanism of TCP slide window, a new set of table structures for session control is designed to record the serial number changes in the process of TCP packet conversion. Besides, in the processing program conversion gateway is embedded control of the said table, which enables the correctness of serial number of the data packets. Problems concerning the detection and handling of the re-communication data packets are also solved neatly.
