A NETWORK TOPOLOGY INFORMATION COLLECTING METHOD

摘要

The invention discloses a network topology information collecting method. Firstly, the topology information collecting equipment sends the topology information collecting requiring messages to the respectively adjacent nodes from the local nodes, the requiring messages include the fields for limiting the messages' transmitting times. The topology information collecting equipment repeatly performs the following operation: the nodes which receive the requiring messages return the responsing messages to the topology information collecting equipment; and the equipment judges whether the messages' transmitting times reach the threshold, if "yes", then the operation ends; if "no", the nodes which receive the requiring messages transmit the requiring messages to respectively all the adjacent nodes. Thus the invention realizes the network topology information collecting.
