PBR结合NQA技术在多ISP接入校园网的设计与仿真

Design and Simulation of PBR Combined with NQA Technology in Multi-ISP Access to Campus Networks

随着学校的发展,校园网的规模逐渐扩大、应用类型逐渐增多,其可靠性和高效性也越来越受到教职工和学生的关注和重视。为了提升校园网的可靠性和灵活性,提出了在多ISP接入场景下采用基于策略路由(Policy-Based Routing,PBR)的负载均衡和基于网络质量分析(Network Quality Analyzer,NQA)出口动态备份等技术的优化改造方案。通过ENSP模拟软件验证了该方案的可行性,并在提升访问互联网的速度、出口线路故障的自适应切换方面的具有优势。

With the development of the school,the scale of campus networks is gradually expanding and the types of applications are gradually increasing.Its reliability and efficiency are also more and more concerned by the staff and students.In order to improve the reliability and flexibility of the campus network,an optimization and modification scheme using Policy Based Routing(PBR)load balancing and Network Quality Analyzer(NQA)export dynamic backup technology in multiple ISP access scenarios has been proposed.The feasibility of this scheme was verified through ENSP simulation software,and it has advantages in improving the speed of accessing the internet and adaptive switching for exit line faults.
