METHOD AND SYSTEM FOR UPDATING TOPOLOGY CHANGES OF A COMPUTER NETWORK

摘要

The invention concerns a method for detecting topology changes of a computer network, said method including mainly daily primary pollings and more frequent secondary pollings between two primary pollings. For each primary polling, the method consists in inspecting all the elements of the network and calculating the checksum for sensitive elements. For each secondary polling, it consists in inspecting only the sensitive elements and calculating a new checksum for each sensitive element. When the most recently calculated checksum differs from the one previously calculated, only data concerning the sensitive element concerned are updated in the topology database.
