吉林省教育学院互联网接入CERNET的出口带宽较窄,访问公众网的速度很慢,在访问CERNET免费地址以外的资源时,要支付高昂的费用。采用基于策略路由的校园网多出口方案可以解决上述问题。策略路由是路由器的一项扩展功能,根据源地址及目的地址选择路由走向进行策略路由配置,通过增加网络出口,大大提高了内外网络互访的速度,降低了网络费用。
Jilin Provincial Institute of Education Internet Access CERNET has a narrow bandwidth for export and slow access to the public network, which pays high fees when accessing resources beyond CERNET’s free address. The use of policy-based routing campus network multi-export program can solve the above problems. Policy routing is an extension function of the router. According to the source address and the destination address, route routing is selected for policy routing configuration. By increasing the network exit, policy routing greatly increases the speed of mutual visits between the inside and outside networks and reduces the network cost.
