本文根据分组交换网的网络规程以及网络能适应恶劣环境的要求,提出了分布式路由建立虚电路的方案.由基本的最小权生成树算法,逐步拓展成为适合拓扑变化,适合业务量变化,适合于用户移动情况下的路由算法;讨论了该路由方案建立虚电路的网络规程,并用计算机模拟了分布式路由建立虚电路的过程,证明了该路由方案的有效性、可靠性和最佳性,最后通过实验验证了路由算法的可行性。
Based on the network protocol of packet switched network and the requirement that the network can adapt to harsh environment, this paper proposes a scheme of distributed routing to establish virtual circuit.From the basic minimum spanning tree algorithm, it gradually expands to be suitable for topological change, suitable for traffic changes, suitable The routing algorithm in the case of mobile users is discussed. The network protocol of establishing virtual circuits in this routing scheme is discussed. The process of establishing virtual circuits by distributed routing is simulated by computer. The effectiveness, reliability and optimality of this routing scheme are proved. Finally, the feasibility of routing algorithm is verified by experiments.
