一种高效的 IP 定位方法

摘要

在中大型网络管理中，IP 定位是最多用到的网络管理功能。为提高 IP 定位的发现效率，提出了一种高效的 IP 定位方法：该方法基于 SNMP 协议，并结合哈希查找技术，通过对相关网络设备 ARP 及MAC 地址表的一系列计算，实现快速精确的 IP 定位。通过实验表明，该方法相比人工定位及全网搜索的 IP定位方法，执行效率更高，定位更精确。%IP location is the most frequen tly used function in the management of large network. In order to improve the discovery efficiency of IP location, this paper presents an efficient method of IP location. Based on the SNMP protocol and the technology of hash search, the method can achieve fast and precise IP location through calculation of ARP and MAC address table of the related network devices. The experimental result indicates that the method is more efficient and precise than the methods of artificial IP location and global search of IP location method.
