Design and Simulation on Campus Redundant Network Architecture in Complex Network Environment

提出一种园区冗余网络架构方案。该方案针对园区网的组网特性,整合各种网络结构的优势和不同网络协议之间的相互兼容性,重点对核心层交换机配备和出口路由规划等问题进行分析与研究,并借助Packet Tracker仿真平台,设计和搭建一个具有冗余容错、负载均衡特性的双核心多出口园区网络拓扑。仿真结果表明,该网络架构能够较好实现设备冗余、链路冗余、网关冗余和路由冗余,从而为园区网的平稳运行提供稳固保障。

Proposes a scheme of campus redundant network architecture.According to the networking characteristics of campus network,the scheme designs and builds a dual-core and multi-export campus network topology with redundancy,fault tolerance and load balance by integrating the advantages of various network structures and the compatibility of different network protocols,focusing on the research and analysis of the problems such as core layer switch configuration and exit routing planning,with the help of Packet Tracker network simulation plat⁃form.The simulation results show that the network architecture can realize equipment redundancy,link redundancy,gateway redundancy and route redundancy well,thereby providing a firm guarantee for the smooth operation of the campus network.
