教育城域网组网方案的确定是教育城域网建设的关键环节,当前存在着多种解决方案,如直接租用裸光纤、直接租用电路、使用以太网接入和使用MPLSVPN接入等,但这些方案并不能很好地运用到西部的教育城域网建设中去。本文根据中国西部地区经济发展水平和电信基础设施的实际情况,提出了一种基于MSTP的教育城域网组网方案,该方案的基本思想是在MSTP技术的帮助下,利用现有的SDH网络把各个学校连接起来,所有的路由交换都由教育信息中心统一完成,接入学校只需提供交换机即可。最后,本文描述了该方案在新疆巴州教育城域网组网中的具体应用及实施效果。
Education metropolitan area network solution is to determine the construction of education MAN key link, there are currently a variety of solutions, such as directly rent bare fiber, direct leased circuits, the use of Ethernet access and use MPLSVPN access, but These programs are not well applied to the construction of education metropolitan area in the west. Based on the economic development level in western China and the actual situation of telecom infrastructure, this paper proposes a networking scheme based on MSTP for education metropolitan area network. The basic idea of this scheme is to use the existing SDH network with the help of MSTP technology Connect all schools, all routing exchanges are completed by the Education Information Center, access to schools only need to provide switches. Finally, this article describes the specific application and implementation effect of the program in the education metropolitan area network of Pakistani state in Xinjiang.
