Document Type and Number:
WIPO Patent Application WO/2018/090852
Kind Code:
A1
Abstract:
A link state packet transmission method and a routing node, applied to a tree topology structure, the tree topology structure comprising a leaf routing node, an intermediate routing node and a root routing node. The method comprises: the intermediate routing node receiving a link state packet sent by a sub-routing node of the intermediate routing node; the intermediate routing node sending the link state packet to the root routing node, and the root routing node being used for gathering the received link state packets to obtain a link state packet set; the intermediate routing node receiving the link state packet set sent by the root routing node; and the intermediate routing node sending, to the sub-routing node of the intermediate routing node, the link state packet set. By using the method of the embodiments of the present invention, the number of link state packets in a network can be reduced, thereby avoiding a broadcast storm.
