Abstract

The present invention provides a traffic forwarding method and device, wherein the method includes: establishing a second tunnel when the first tunnel enters a blocking state, wherein, during the process of establishing the second tunnel, forwarding information of the first tunnel Update to the forwarding information of the second tunnel; forward the traffic according to the updated forwarding information in the second tunnel; through the present invention, it solves the problem that the upstream and downstream devices need to be upgraded to support the updated protocol function or field in the related technology to complete the tunnel It improves the efficiency of traffic forwarding in the tunnel.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a flow forwarding method and device. Background technique [0002] Multi-Protocol Label Switching Traffic Engineering (MPLS Traffic Engineering, referred to as MPLS-TE) tunnel is calculated by user-specified or constrained shortest path first algorithm (Constrained Shortest Path First, referred to as CSPF) to generate a specific path, and through the resource reservation protocol (Resource Reservation Protocol, RSVP for short) protocol reserves bandwidth resources and allocates labels, and establishes a tunnel based on label switching to forward traffic. The MPLS-TE tunnel, TE tunnel, te_tunnel, and tunnel mentioned in the present invention are TE tunnels established through the RSVP protocol. [0003] The current TE tunnel protection method is aimed at the status protection of the interfaces or router nodes passing through the tunnel part or complete path, and notifies the up...
