基于三层交换VLAN的图书馆网络体系

Application of VLAN Based on Three-Layer Switching in Network System of Library

对VLAN间的通信和中心第三层交换机的原理及应用优势进行科学分析,着重从多层交换网络体系的构建、VLAN的合理规划、采用安全有效管理策略三个方面,对图书馆网络体系的构建进行探讨,进而提出基于中心第三层交换VLAN的图书馆大型网络体系规划。

The application advantages of VLAN （ Virtual Local Area Network） were elaborated,with analysis of the principles of communication and three-layer switching. The construction of network system for libraries was discussed, focusing on multiply layer switching, rational planning of VLAN and application of safe, effective management strategy. At last, the planning of scaled network system for library was proposed, based on VLAN with three-layer switching.
