校园网多出口服务体系设计分析

Analysis and designing of campus multi-export server system

伴随校园网络的快速发展,校园网络出现了两个瓶颈,一是校内用户数的快速增长造成校内可用公网IP地址的短缺,二是原有教科网出口带宽不能满足校内用户的需求.面对这样的问题,许多校园网都采用了接入多个ISP和NAT技术相结合或者升级原有链路带宽的方式来解决.本文结合本人的工程经验,介绍了校园网多出口服务体系的设计思路和方法.

With the rapid development of campus network, two bottlenecks appear. One is the shortage of available IP address because of the rapid growth of campus users. The other bottleneck is that the old CERNET bandwidth can＇t meet with the need of campus users. To solve these problems, some campus networks adopt the means of combine several ISP with NAT technology or increase the old link bandwidth. Based on the author＇s engineer practice, the designing idea and method of campus multi-export serve system is mainly discussed in this paper.
