摘　　要：随着我国教育信息化的大力发展,对网络的应用和要求越来越高,原先的网络无论在速度上,还是服务质量上都已经无法满足广大师生的要求了。对于高校校园网的改造已经迫在眉睫。以实际项目为背景,简述两种校园网多出口解决方案。提出了一种新的模型,即在现有校园网的基础上,通过使用GRE隧道技术,实现校园网的多出口、多服务的要求。用户既可采用原有方式通过教育网接入Internet,也可采用电信等其他网络,高速接入Internet。文中方案采用在客户端路由的方式,可以根据用户要求,灵活选择教育网出口或者其他ISP提供的网络,并实现灵活计费,满足不同用户的要求。目前此方案已经在某高校进行试验,结果证明了它能有效地提高网速。此方案不仅可用于校园网,也可用于企业或者小区的改造。With the development of education informationization along our country, the need of the network has increased. Both of the speed and the quality of original network have been unable to meet the demands of teachers and students in campus. The change of campus＇ network is needed. Based on the actual project, summarized two kinds of multi-export network solution. And proposed a new model, that is, based on the existing campus network and realize the requirements of more exports,multi-service by the use of GRE tunnels technology. Users can use the original way that is through education network to visit Internet or use other networks server to visit internet. This model used the way of route on client which is flexible the user to chooses the way they wanted to visit internet and easy to billing and satisfied the requirement of different user. At present, this plan has already taken experiment in a university and the result proven that it can enhance the network speed effectively. This plan not only can use in the campus network, hut also can use in the enterprise and so on.
