Method and apparatus for path switching

摘要

The present invention discloses a path switching method and apparatus in a network comprising at least a first path and a second path. For an incoming traffic flow, it is determined that any of tunnels on the first path of all levels into which the incoming traffic flow is multiplexed is of a failure status. The incoming traffic flow is then forwarded via the second path. Herein, for the first path, one or more traffic flows are multiplexed into a tunnel, and one or more higher level tunnels are multiplexed into a lower level tunnel.

主权项

1. A path switching method in a network comprising at least a first path and a second path, the method comprising:
forwarding, by a path switching apparatus, an incoming traffic flow via the first path, wherein for the first path, one or more traffic flows are multiplexed into a tunnel, and one or more higher level tunnels are multiplexed into a lower level tunnel; for the incoming traffic flow, determining, by the path switching apparatus, that out of a plurality of tunnels on the first path of all levels into which the incoming traffic flow is multiplexed, any one of the plurality of tunnels is of a failure status; and forwarding, by the path switching apparatus, the incoming traffic flow via the second path instead of the first path based on the determination.
