Method and apparatus for processing labeled flows in a communications access network |
摘要 |
A system and method is provided for managing access communications between the service edge of a communications service provider and a customer. Access communications are carried in the form of carrier-tagged flows, the communications traffic being appended with carrier tags having significance to handling of the traffic through access network elements. A building aggregation system is provided which couples to customer premise equipment and interfaces customer flows to carrier-tagged flows used in the access network. |

1. An apparatus comprising:
a layer 2 switch configured to receive a first carrier-tagged traffic flow from a service edge via a first multiprotocol label switching (MPLS) switched path, the first carrier-tagged traffic flow having a carrier tag, wherein the layer 2 switch is further configured to identify a second MPLS switched path based on a flow identifier included with the carrier tag of the first carrier-tagged traffic flow, wherein the flow identifier comprises a pseudo-wire tag or a virtual local area network (VLAN) tag, wherein the layer 2 switch is further configured to remove the flow identifier from the carrier tag of the first carrier-tagged traffic flow, and to switch the first carrier-tagged traffic flow, after assigning a new carrier tag without the flow identifier, to a building aggregation system configured to aggregate a plurality of services via the second path. |
