摘要
为了达到优化校园网的目的,通过OPNET仿真方法,从网络拓扑结构到资源合理配置两方面进行优化设计。对多级网络和三级网络环境下网络的系统时延、服务器响应速度和吞吐量进行仿真。结果表明,控制交换级数可以有效降低系统时延,提高网络性能。建议中小型网络采用"核心交换-汇聚交换-节点交换"的三级交换拓扑结构。
The optimization design for both the network topology and the rational allocation of resources was carried out by OPNET simulation for the purpose of the campus network optimization.The system time-delay of network,the response rate and the throughput capacity of the server were simulated under the conditions of multi-stage network and three-stage network.The simulation result shows that the control of switching stages can efficiently reduce the system time-delay and improve the performance of the network.It is recommended that the small and middle networks adopt the three-stage topological structure of ＂core switching-aggregation switching-nodal switching＂.
