摘　　要：深入分析了传统虚电路和数据报的主要优缺点,根据因特网的应用和发展要求网络层提供可靠的数据传输,实现动态路由和有效地支持网络安全,提出了一种网络层数据传输的新方式,称为可定向路径链。从数据传输的可靠性、动态路由和网络安全三方面探讨了可定向路径链的特性。研究表明:可定向路径链是一种动态虚电路,既有传统虚电路和数据报的优点,又克服了二者的不足,还能有效地支持网络安全,如杜绝IP源地址仿造和实现网络追踪。After analyzing merits and faults of traditional virtual circuit and datagram to meet the future demands of rehale network layer data transmission of network application and development, a new mode of network layer data transmission called orientable path chain was put forward. Oricntable path chain was studied in reliable connection-oriented service, network security quahty and network survivability. The study shows that oriemable path chain is a new type of virtual circuit, it not only has advantades of traditional virtual circuit and datagram but also overcomes their disadvantages, and it can efficiently support network security such as avoiding IP source address forgery and supporting network traceback.
