Abstract
A method and an apparatus for rapidly resuming, at times of failures, network traffic in a connection-oriented network by using an alternative route pre-computed and stored locally in nodes along an initial route without requiring signaling of upstream nodes or a master server.
Claims2
A network for forwarding packets from a source device to a destination device, said network including a plurality of network elements including nodes and connecting links, a master server for monitoring the network and establishing an initial route between the source device and the destination device, wherein at least one node comprises:
- a processor to compute an alternative route for the initial route;
- a storage space to store the initial route and the alternative route;
- a mechanism to detect failure in a downstream network element in the initial route;
- and
- a forwarder to automatically forward a packet to the next node.
