基于SNMP协议的网络拓扑发现算法设计与实现

Design and implementation of campus network topology discovery system based on SNMP

网络拓扑发现是网络管理的基础,对网络的故障检测与定位、性能分析具有重要意义。本文提出了一种基于简单网络管理协议(SNMP)获得路由器、交换机MIB库中的相关数据后,并根据ARP协议、生成树协议推导出网络拓扑结构的算法。依据该算法思想,在本校校园网环境中,使用JAVA+PHP+SQL SERVER实现了基于WEB的网络拓扑搜索功能,可以快速的、准确的发现网络中设备以及设备间的连接关系,逐步实现校园网网络管理透明化。

Network topology discovery is the basis of network management, and it has important significance for fault detection and location and performance analysis. the paper studies and analyzes the basic theory of topology discovery and technology based on simple network management protocol（SNMP） and based on ARP protocol, generation tree protocol. Based on the idea of the algorithm, in the campus network environment,Java＋ Php ＋ SQL Server realized web based network topology search function, can quickly and accurately find connection between equipment and equipment in the network, the progressive realization of the campus network management transparency.
