Abstract:
1. A method comprising: selecting a traffic path from one or more traffic paths with each traffic path having traffic path parameter information and the selected traffic path being based on the associated traffic path parameter information; selecting a first transport trail from one or more transport trails with each transport trail comprising at least one of a temporary virtual circuit and a permanent virtual circuit and having associated transport trail parameter information comprising one or more of a transport trail bandwidth, a transport trail reservation threshold, and a transport trail administrative cost, the first selected transport trail being based on the associated transport trail parameter information; assigning the selected traffic path to the first selected transport trail if the first selected transport trail is determined to be suitable for assignment; preempting the assignment of the selected traffic path to the first selected transport trail in response to a change in at least one of the transport trail bandwidth parameter, the transport trail reservation threshold parameter, and the transport trail administrative cost parameter associated with the first selected transport trail; selecting a second transport trail from the one or more transport trails and the second selected transport trail being based on associated transport trail parameter information; and assigning the selected traffic path to the second selected transport trail if the second selected transport trail is determined to be suitable for assignment; wherein the traffic path parameter information comprises one or more of a traffic path bandwidth, an over-subscription factor, a placement priority or a holding priority.
