动态显示网络系统的拓扑图是网络管理系统的基本功能,目前常见的拓扑搜索算法大部分都是基于网络层的,不能对链路层的动态网络拓扑进行搜索且不能发现和管理虚拟网。提出了一种利用SNMP协议、ICMP协议和ARP协议三种协议相结合的网络拓扑搜索算法,发现ATM网络的链路层网络拓扑和提取ATM虚拟网的配置信息。最后,以哈工大通信所的某一子网(ATM虚拟局域网)为例,对此算法进行了验证。
Dynamically displaying the topology of the network system is the basic function of the network management system. Currently, most of the common topology search algorithms are based on the network layer, and can not search the dynamic network topology of the link layer and can not discover and manage the virtual network. A network topology search algorithm using SNMP, ICMP and ARP protocols is proposed to discover the link layer network topology of ATM network and to extract the configuration information of ATM virtual network. Finally, a certain sub-network (ATM Virtual Local Area Network) of HIT is used as an example to verify this algorithm.
