摘　　要：给出基于核心交换机、出口路由器等设备,并采用静态路由、策略路由、地址转换、自动侦测、负载分担等技术的多互联网服务提供商网络出口接入方案,研究了如何避免网络瓶颈,优化网络服务质量.测试数据表明,服务器在做多出口发布后,数据包丢包率减小,平均延时减小,路由跳数减少,网络服务质量明显改善.园区网网络服务质量和健壮性也明显改善.Based on a core switch and WAN router, a multi-interface connection with intemet service providers was proposed, which used the technologies such as static routing, policy-based routing, network address translation, auto detect, and load balancing. How to avoid the network bottleneck and optimize the quality of network services was also research on. The results show that using the proposed method, packet drop ratio, average link delay, and route hop were reduced, and the servers＇ service quality was obviously improved. Meanwhile, the service quality and robustness of the internal network on campus were also significantly improved.
