Patent ID: 8457119

Claim:
A method of operating a communications network, comprising: providing a plurality of redundant links between a first network node and a second network node; associating a first identifier with a first one of the plurality of redundant links and a second identifier with a second one of the plurality of redundant links, the first and second identifiers being associated with a regulatory constraint, the regulatory constraint comprising at least a portion of a public law enforceable by a governmental body; and routing traffic that is marked with the first identifier to the first one of the plurality of redundant links and traffic that is marked with the second identifier to the second one of the plurality of redundant links so that operation of the communications network is in compliance with the regulatory constraint; wherein the communications network is a multiprotocol label switching protocol network, wherein the traffic comprises packet traffic, and wherein the first identifier is a first multiprotocol label switching network label and the second identifier is a second multiprotocol label switching network label; wherein the first one of the plurality of redundant links is associated with a first inter-exchange carrier and the second one of the plurality of redundant links is associated with a second inter-exchange carrier and the first inter-exchange carrier and the second inter-exchange carrier are active simultaneously to carry the traffic between the first network node and the second network node; and wherein the multiprotocol label switching protocol used in the communications network is independent of packet transport protocols used by the first and second inter-exchange carriers, respectively.
