专用网路由方法的改进及抗毁策略

Improved Routing Algorithm and Rerouting Strategy for Private Networks

饱和路由方法是Ｅｕｒｏｃｏｍ推荐的一种路由方法．由于其高可靠性，在分组交换网中得到广泛应用．但是，其固有弱点在于泛洪式广泛信息往往不可避免地带来网络中过多的信息冗余，从而导致网络性能下降．本文在保证网络可靠性的前提下，提出了直达路由与抗毁相结合的策略．理论分析与计算机仿真表明，此策略可以明显地改善网络性能，同时不影响其鲁棒性．

The Flooding Routing Algorithm (FRA) is recommended by Eurocom.Due to its robustness,FRA has now been widely applied to packet switching networks.However,the inherent drawback of FRA is that the flooding broadcasting characters may inevitably cause excessive network traffic redundancy with degraded network performance.This paper develops a so called Direct Routing Algorithm coupled with a Rerouting Strategy.Theoretical analysis and computer simulations show that the proposed scheme can substantially improve the network performance while maintaining robustness.
