Abstract:
1. A method for creating a permanent sub-network connection in a network of connected nodes, the method comprising: discovering neighbors of each node in the network of connected nodes and link status with a signaling and routing protocol; distributing routing topology information and optimal route determination with the signaling and routing protocol; defining a route including a working path for a permanent sub-network connection in the network of nodes from an ingress node to an egress node, wherein the route is defined explicitly, automatically through the signaling and routing protocol, and in combinations thereof; defining a time out period to be associated with the permanent sub-network connection and initiated in response to the detection of a failure in the permanent sub-network connection, the time out period defining a time over which the failure in the permanent sub-network connection is permitted to be corrected prior to a tear down of the permanent sub-network connection; provisioning the route; distributing a route description to each node along the route from the ingress node to the egress node; and configuring each node along the route in accordance with the route description to provide data traffic services from the ingress node to the egress node; wherein the permanent sub-network connection comprises a permanent grouping of one or more paths that pass through a node in the network which is set up and torn down with the signaling and routing protocol.
