摘　　要：大多数校园网早期使用传统的三层架构模式部署,易于实现快速组网。但随着终端数量不断增多,校园网带宽发生了爆发性的增长,校园网的QoS保障也面临新的挑战,高校师生不断增长,多业务用网需求无法得到满足。本文采用一种扁平化架构设计校园网,并通过IPFIX协议精准识别流量后进行处理,可有效降低网络拥塞。基于CoA灵活策略处理,可实现校园网与运营商网络的有机整合。考虑网络安全管控因素,在网络边界部署代拨设备实现网络隔离,并支持校园网建立高并发宽带通道连接运营商核心网,实现校园网与多运营商网络的有机融合。Most of the early campus networks use the traditional three-tier architecture mode deployment,which is easy to achieve rapid networking.However,with the increasing number of terminals and the explosive growth of the bandwidth of the campus network,the QoS guarantee of the campus network is also facing new challenges.With the continuous growth of college teachers and students,the demand for multi service network cannot be met.In this paper,a flat architecture is used to design the campus network,and the traffic is accurately identified by IPFIX protocol,which can effectively reduce network congestion.Based on the flexible strategy processing of CoA,the organic integration of campus network and operator network can be realized.Considering the factors of network security management and control,the network isolation is realized by deploying the proxy equipment at the network boundary,and the high concurrent broadband channel is supported in the campus network to connect the core network of the operator,so as to realize the organic integration of the campus network and the multi operator network.
