| 摘 要： | 该文对当前网络层拓扑发现方法进行了介绍,并针对基于SNMP的发现方法的不足之处提出改进。对网络层路由器进行广度优先搜索。利用SNMP获取路由器上路由MIB变量的值,进行综合分析,找出路由器与路由器、路由器与子网之间的连接关系;同时,利用多线程对各子网进行扫描,找出子网中所有的在线设备。改进方法提高了拓扑发现的高效性和快速性。

| Abstract: | In the first part of this thesis, we introduce the current network layer topology discovery methods, and improvement that achieve high efficiency and speed based on SNMP According to breadth-first-search traversal algorithm, we conclude the connection between router and router, router and subnet by getting the value of route MIB variables of routers. In the meantime, we use multi-thread to scan all subnets to get the information of alI active devices. |
