Abstract

The invention discloses a routing convergence method and system. The method includes the steps that a network server collects network topology information of a corresponding network; a path with the fewest path hops is searched for on the basis of the network topology information and serves as a shortest path between each source node and the corresponding destination node, the shortest paths between the source nodes and the corresponding destination nodes are converted into a full-path routing list according to link information of network nodes of the networks, and the full-path routing list is sent to the network nodes of the corresponding networks so that the network nodes can carry out routing convergence by inquiring the full-path routing list. According to the routing convergence method and system, when routing convergence is needed, the network nodes do not need to calculate the paths, concentrated routing planning is carried out on the basis of the full-path routing list, the network convergence speed and network maintenance efficiency can be improved, network control capacity can be improved and transverse extension of a network structure is facilitated.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a route convergence method and system. Background technique [0002] OSPF (Open Shortest Path First) is deployed in the IDC (Internet Data Center, Internet Data Center). Usually, for fast convergence, all network nodes in the IDC are deployed in the same area (non-backbone area). Network nodes are directly interconnected through network broadcast links, and become OSPF neighbors through hello message handshake. In order to prevent OSPF protocol calculation performance loss, the OSPF network type is set to P2P (Peer to Peer, peer-to-peer computing) mode to prohibit OSPF DR election on the broadcast link. The cost of each link in the domain is the same value 10. [0003] OSPF adopts the distributed routing calculation method based on the link state. Network nodes running OSPF protocol broadcast their own link information and OSPF neighbor information in the domain. After ...
