校园网双出口接入的实现与改造

随着网络技术的不断发展,Internet上的资源得到了不断丰富,但目前我国高校对此的利用率却不高。众所周知,我国CERNET与公众网的互连存在着带宽瓶颈问题,它们之间互访速度却很慢,这束缚了一些高校网络应用水平的提高。本文以我校实现校园网双出口接入Internet为实例,介绍如何采用双出口措施实现校内用户快速访问外部资源,校外访问者快速访问我校网站的策略与方法。本方法不仅解决了加快与公网互连速度问题,而且能够实现链路冗余和解决内网安全等问题。

Reform and Implementation of Double-Export-Links Campus Network

With the development of network technology, the resources provided by internet are being enriched constantly.Whereas, in our country, university＇ s utilization ratio of resources on internet is low currently. It is well known that there is a bottleneck between public network and CERNET, which causes the very slow velocity to access each other and limites the enhancement of network application＇ s level in some universities. Through example of double-export-links campus network in our college,this paper introduced how to access outer resources for inner users or to access our college＇ s webserver for outer guests at a high speed by using double-export-links. This method not only solved the problem of speeding the velocity of conneetion between campus network and public network but also realized the chain circuit redundancy and inner network＇ s safety.
