Abstract
A connection oriented communications network has a plurality of nodes including a plurality of edge nodes. The network is arranged to define a primary tunnel connecting a primary one of the edge nodes to another edge node and a secondary tunnel connecting a secondary one of the edge nodes to another edge node. The network is arranged to enable switching of traffic from the primary tunnel to the secondary tunnel in the event of detection of a failure in the primary tunnel.
Claims11
A connection oriented communications network comprising:
- a plurality of nodes including a plurality of edge nodes, the network configured to:
- define a primary tunnel communicatively connecting together a primary pair of the edge nodes;
- define a secondary tunnel communicatively connecting together a secondary pair of the edge nodes that is different from the primary pair of the edge nodes;
- and
- control customer equipment, via an instruction sent by a first ingress node or a second ingress node to the customer equipment, to switch traffic from the primary tunnel to the secondary tunnel responsive to detecting a failure affecting the primary tunnel.
A node for a connection oriented network having a plurality of edge nodes, the node configured to:
- identify a primary tunnel communicatively connecting a primary pair of edge nodes;
- identify a secondary tunnel communicatively connecting a secondary pair of the edge nodes that are different from the primary pair of edge nodes;
- and
- control customer equipment, via an instruction sent by a first ingress node or a second ingress node to the customer equipment, to switch traffic from the primary tunnel to the secondary tunnel responsive to detecting a failure affecting the primary tunnel.
