使用PVLAN设计有利于信息化教学的校园网

很多校园网因规划设计不合理而导致其对信息化教学的服务程度不高，校园网应不仅仅只提供简单的上网功能，更需要把各种信息化功能的服务器高速无缝地融合到校园网中，为此提出在交换机上使用PVLAN（Private VLAN）技术。根据校园功能区不同划分校园网，使用PVLAN中的Community、Isolated VLAN特点来进一步细化VLAN划分和数据的流控，借助Promiscuous端口模式的特性，灵活接入各种服务器，给师生的教学、学习、办公、实训提供快捷、安全和全方位的信息化服务。

Using PVLAN to Design Campus Network for Informatization Teaching

Many campus network service in the informatization teaching level is not good due to the unrational design of campus network. It is need that campus network not only provides the function to access internet, but also integrates all kinds of information servers quickly and seamlessly. This paper proposes a PVLAN （Private VLAN） technology on the switch to divide campus network based on different functional areas in the campus. Using Community, Isolated VLAN features in PVLAN, the VLAN partition and data flow control are further refined. With the characteristics of Promiscuous port mode, various servers are flexible accessed to provide fast, safe range of information service for teaching, learning, working, training of teachers and students.
