METHOD AND NODE DEVICE FOR REALIZING THE NETWORK TOPOLOGY DISCOVERY

摘要

Method for realizing the network topology discovery, which relates to the field of internet technique, includes: receiving the network topology inqui ring command from the previous node, the network topology inquiring command includes the address information of the specified node; feeding back the net work topology information of this node to the specified node, the network to pology information of this node includes the connection information between this node and the previous node. The invention also discloses a node device. With the technique scheme provided by this invention, it can obtain the con nection information between the nodes in the network topology information, n amely the connection state of point-to-point.
