Abstract

The invention provides a route processing method and device. The method comprises the steps of receiving route notification information sent by a border node of a second area, wherein the route notification information carries route information of the second area; according to the route information of the second area, generating link state advertisement (LSA) information, wherein the LSA information comprises area attributes, link states and IP prefixes of network nodes of the second area; according to the link states of the network nodes of the second area, determining a downstream network node of a tunnel egress node; and according to the IP prefixes of the network nodes of the second area, determining an IP prefix of the downstream network node, generating a route with a destination address as the IP prefix of the downstream network node, and setting an outbound interface of the route as an identifier of a TE tunnel. Through adoption of the method, a tunnel ingress node can introduce the TE tunnel to the route, so as to enable the TE tunnel to involve in route computation to realize an automatic route release function of the TE tunnel.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a route processing method and device. Background technique [0002] Network congestion is the main problem that affects the performance of the backbone network. The cause of congestion may be insufficient network resources, or local congestion caused by unbalanced load of network resources. TE (Traffic Engineering, traffic engineering) can be used to solve the congestion caused by unbalanced load. question. TE monitors network traffic and network node loads in real time, and dynamically adjusts traffic management parameters, routing parameters, and resource constraint parameters, etc., to migrate the network operating status to an ideal state, optimize the use of network resources, and avoid congestion caused by unbalanced loads. [0003] MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching) TE technology combines MPLS technology and TE techn...
