Embodiment Construction

[0043] The embodiment of the present application provides a node configuration method, a controller, and nodes. The flooding process of service topology information between nodes is different from the flooding process of control topology information. Each node will only flood services from a specified interface. Topology information, without flooding service topology information to the adjacent nodes of all interfaces. The flooding path of service topology information is reduced, and the burden of network bandwidth is reduced.

[0044] It should be noted that the terms "first", "second" and "third" in the specification and claims of this application and the above drawings are used to distinguish similar objects, rather than to limit a specific order or sequence . It is to be understood that the above terms are interchangeable under appropriate circumstances such that the embodiments described herein can be practiced in sequences other than those described herein. Furthermore...

Abstract

The invention provides a node configuration method, a controller and a node. The flooding path of the service topology information is reduced, and the burden of the network bandwidth is reduced. The method comprises the steps that firstly, a controller determines a target network according to an original network, the original network is used for flooding control topology information, the target network is used for flooding service topology information, and flooding paths in the target network are fewer than those in the original network; next, the controller determines attributes of all interfaces of each node, where the attributes of the interfaces include a first attribute and a second attribute, the interface having the first attribute is used for flooding the traffic topology information, and the interface having the second attribute is not used for flooding the traffic topology information. And furthermore, the controller generates first configuration information according to the attributes of all the interfaces of each node and sends the first configuration information corresponding to each node to each node, and the first configuration information is used for indicating that each node configures the attributes of all the local interfaces.

Description

technical field [0001] The present application relates to the communication field, in particular to a node configuration method, a controller and a node. Background technique [0002] Open Shortest Path First (OSPF) is a link state-based interior gateway routing protocol. Link state refers to the parameters of a router interface or link. What is exchanged between routers is not a routing table, but a link-state advertisement (Link-State Advertisement, LSA). Each router has its own link state, called the local link state, and these local link states are propagated in the OSPF routing domain until all routers have a complete and identical link state database. [0003] The current flooding process of OSPF is: a node receives an LSA from an interface, and will propagate this LSA through all other interfaces of the node. This means that other nodes will receive the same LSA from many interfaces. This mechanism ensures the reliability of the network, but a large number of redu...
