Abstract
A method of coherently provisioning one or more paths through a transport network is disclosed. In other words, none of the traffic paths are provisioned unless all of the traffic paths can be provisioned. All of the nodes in one or more transport networks are listed that must be configured to provision all of the proposed traffic paths, and all of the nodes are checked, one after another, to ensure that each node can, in fact, provide all of the resources needed to establish all of the proposed traffic paths before any of the traffic paths are actually provisioned. As each node is visited, the set-up message directs each node to reserve, but not actually provision, the resources to be provided by that node for all of the proposed traffic paths. When all of the nodes have been visited, the set-up message re-visits each node and directs each node to actually provision the resources that had been previously reserved.
