我院校园网总体性能不错,但自从学院内网中所有子网实现互联互访之后,网络中断的故障时有发生,有时甚至引起全网瘫痪。“不能上网”即网络中断的俗称,一直都是我院校园网维护中常见故障,本文从中选取几类典型加以研究,并从技术及管理角度探讨我院校园网络的性能提升的初步解决办法。 Our campus network overall performance is good, but since all the subnets in the school network to achieve interoperability, network interruption of the fault occurred from time to time, and sometimes even caused the entire network to be paralyzed. “Can not go online” is commonly known as network interruption, which has always been a common failure in the maintenance of campus network of our college. This article selects a few typical examples to be studied, and discusses the initial solution to the performance improvement of campus network in our college from the perspective of technology and management.
