民航华东DDN网实时路由跟踪的功能实现

Realization of Real-time routing tracking in East China Civil Aviation DDN Network

实时跟踪可以说是路由跟踪的一种不可忽视的实用程序,其主要的目的就是为了能够对于IP数据报访问目标进行确认而使用的一种路径。Tracert命令则是使用IP生存时间(TTL)字段以及ICMP错误消息去低从一个主机到网络上其他主机的路由进行确认。实时路由跟踪功能是民航华东DDN网新型网络管理系统的一个颇具特点的功能模块,它基于完整的用户资料以及网络拓扑,通过递归式访问相关路由器并提取相关虚电路信息,最终将一条具体业务的实时路由完整展现,为相关业务的故障定位提供了极大的便利。

Real-time tracking can be said to be a useful program for routing tracking. Its main purpose is to be able to confirm the IP Datagram access target using the path. Tracert command is to use the IP lifetime （TTL） field and the ICMP error message to low from a host to the network The routing of other hosts is confirmed. Real-time routing tracking is a characteristic function module of the new network management system of DDN network in East China. It is based on complete user data and network topology, and accesses related routers recursively. The virtual circuit information is extracted, and the real-time routing of a specific service is presented in the end, which provides great convenience for fault location of related services.
