基于多运营商的校企校园无线网络共享实践

Practice of campus wireless network sharing between school and enterprise based on multi-operators

在校园网基础上,引入运营商代拨接入服务,是目前解决校园网出口带宽、用户流量资费等供需矛盾的重要手段。当前与运营商真正开展此类服务合作的学校大多集中在高职院校,且往往涉及到线缆的重新铺设,校园网自建自营高校还较少涉足。以校园网自建自营的高校为研究背景,提出将校园无线网络作为改造切入点,以与运营商共享无线物理链路的方式,将运营商引入高校合作的新运营策略。从管理、技术、用户身份认证和网络安全四个方面提出了多运营商共享的校园无线网络改造思路,研究了实现原理和改造后的无线网拓扑结构。以南开大学为例,进行了合作运营策略及相关部署实施的详细介绍,为其他高校校园网引入多运营商进行合作提供了可行的技术路线和可参考的改造方案。

On the basis of campus network,it is an important means to solve the problems related to bandwidth,charge and other contradictions between supply and demand in campus network by introducing operators for dialing-in access service at present.Most of the schools that are really engaged in such cooperation are higher vocational colleges currently,moreover,it is often related to rerouting of cables and there are few universities with independent construction and self-operation.Taking the campus network self-built and self-operated universities as the research background,this paper proposes a new strategy that takes campus wireless network as the starting point for the transformation and introduces operators into university cooperation by sharing wireless physical links with the operators.Based on the four aspects of management,technology,user authentication and network security,this paper puts forward the transformation ideas and studied the realization principle and the wireless network topology after construction.The detailed introduction of cooperative operation strategy and relevant reforming technologies is carried out by taking Nankai university as the example.It provides certain lessons and reference other university to introduce multiple operators to cooperate.
