摘要
名址分离协议可以有效解决当前网络的扩展性问题。首先分析了名址分离模型,介绍了名址分离通信流程,然后针对目前LISP网络内存在的问题提出了一种解决方法。该方法通过可靠泛洪算法,将分散在各个入口隧道路由器内部的离散的映射信息逐渐扩散到骨干网的每个节点,在骨干网内形成一致的映射数据库。入口隧道路由器根据本地映射数据库进行数据封装,可以解决因查询映射服务器失败导致网络不通,增强网络的可靠性。
LISP （Locator Identify Separation Protocol） could efficiently solve the scalability problem of current networks. Firstly, LISP model is analyzed, the communication process of LISP described, and then a solution to the problem in current LISP network is proposed. The proposed solution, based on the reliable flood algorithm, spreads the discrete mapping information which in every ITR （Ingress Tunnel Router）, into each node of the backbone network, thus forming a consistent mapping database in the backbone network. ITR based on the local mapping database,implements data encapsulation. This meth- od could solve the inactive problem of LISP network resulting from map-server failure, and thus enhance network reliability.
