摘要: 合适的路由选择和设计不仅可以优化网络效能,还可以在一定程度上提高网络的安全性和可靠性。本文依据实体网络拓扑,利用OPNET搭建仿真环境,对动态路由协议中的RIP、OSPF和EIGRP三种协议的性能进行仿真对比分析。仿真结果表明,EIGRP在路由收敛时间以及网络队列时延上均具有较大性能优势,但由于EIGRP为思科设备私有协议,使得该协议的进一步推广受到考验;RIP受其算法限制,比较适合小型网络;OSPF协议由于其对各类规模网络均有不错的支持,所以其应用范围最广。网络路由协议的选择和设计要根据网络的实际情况具体问题具体分析,而在实际大型的网络中,静态和动态路由协议通常会被同时采用,以确保网络综合效能的最大化。

Abstract: The appropriate route selection and design not only can optimize network performance, but also can improve the safety and reliability of the network to a certain extent. This paper, based on physical network topology, uses OPNET simulation environment to simulate and comparatively analyzes the performance of dynamic routing protocols RIP, OSPF and EIGRP. Simulation results show that, on the routing convergence time and network queue delay, EIGRP has bigger perfor-mance advantages, however, because EIGRP is Cisco’s proprietary protocol device, the further promotion of it is challenged; RIP algorithm, subject to restrictions, is more suitable for small networks; OSPF protocol has good support for networks of all sizes, and it has the most extensive range of applications. Selection and design of network routing protocol should be based on the actual situation, but in the actual large-scale networks, static and dynamic routing protocol will usually be adopted at the same time, to ensure the maximum effectiveness of the integrated net-work.
