说明：  本文在阐述网络发展的现状和趋势的基础上，着重分析了两种内 部网关路由选择协议砒P和OSPF协议的实现机制和性能特点。对P 协议是基于距离矢量算法的。OSPF协议是基于链路状态算法的。本 文的工作重点是对上述两种协议分别从类型，封装，路径特征，邻居 发现和支持，路由选择数据的分发，对变化的响应，路由表计算，健 壮性／可靠性以及安全性等方面进行了对比分析，并对它们存在的安 全漏洞进行了初步的分析说明。根据以上的分析，通过On忸T软件， 本文设计了一个10km×10km规模大小的网络仿真模型，配置了相应 的流量和IP地址，并选取了路由协议网络收敛性，协议开销，网络 延时以及链路修复四个仿真性能参数进行仿真，最后通过对仿真结果 的分析得出以下结论：对P协议适合于网络规模较小、拓扑结构比较 简单、性能要求不严格和易用性要求较高的环境，而OSPF则适合于 网络规模大、拓扑结构复杂和性能要求高的环境，因此要根据网络特 点合理的选择路由协议。
(This paper described the status and trends of network development on the basis of analyzes of two Ministry gateway routing select the protocol arsenic P and OSPF protocol implementation mechanism and performance characteristics. P The protocol is based on the distance vector algorithm. The OSPF protocol is based on link-state algorithms. This The text s focus is on these two agreements, respectively, from the type of package, the path characteristics, neighbors Discovery and route choice of data distribution, changes in response, the routing table calculation, and health Zhuang/reliability, and security aspects of a comparative analysis, and they are safety The full loopholes in the preliminary analysis shows. According to the above analysis, On to blush T software Designed a 10km x 10km scale the size of the network simulation model, configuration, corresponding Traffic and IP address, and select the routing protocol convergence, protocol overhead, network Delay and link repa)
