基于IPv4的路由信息协议软件实现

Software Implement of Route Information Protocol Based on IPV4

为了解决人工配置路由表比较复杂的问题,对路由信息协议(RIP)进行了比较彻底的分析,包括其工作原理、报文格式和主要实现机制,为了以软件的形式验证其动态路由功能,对其某些机制进行了简化和重新设计,同时结合其报文格式和实际需求对路由表的结构也进行了重新架构,实现完成后将其移植到软件路由器上对其正确性进行了检验,得到了预想的结果,这同时也提供了对其他的动态路由协议进行软件实现的基础。

In order to dispose the problem of the configuration of route table artificially more complicated, thorough the analysis of route information protocol（RIP）, including the general principals, message format and main mechanisms, in order to verify its dynamic route function in the form of software ,some mechanisms are simplified and redesigned. At the same time redesigns the structure of the route table according with its message format and actual demand. At last transplants it to the software router and examines its exactness after realized it, and gets the anticipated result, offerring the foundation on the software implement of other dynamic route protocols.
