本文基于高性能路由器,对影响集成IS-IS协议路由稳定性的问题进行了深入研究,通过对协议包处理流程的优化有效地减少了不稳定链路上LSP的产生,高效地处理了最大LSP顺序号的问题,通过理论分析得出了LSP交互的优化方案,利用基于未确认的LSP检测机制研究了减少LSP重传问题。 In this paper, based on the high-performance routers, the problems that affect the routing stability of the integrated IS-IS protocol are studied in detail. By optimizing the protocol packet processing flow, the generation of LSPs on the unstable links is effectively reduced and the maximum LSP Order number problem, through the theoretical analysis of the LSP interaction optimization program, the use of unacknowledged LSP detection mechanism to reduce the LSP retransmission problem.
