Abstract: A multiprotocol label switching (MPLS) node sends an output packet including control information and payload data. The MPLS node is configured to: receive an input packet including the payload data, from a first pseudo-wire segment; modify an encapsulation format of the payload data of the input packet to generate the output packet; and send the output packet to a second pseudo-wire segment. The MPLS node can also be configured to support the opposite operating direction, that is an MPLS, node may be configured to receive an input packet including the payload data from a second pseudo-wire segment; modify an encapsulation format of the payload data of the input packet to generate an output packet; and send the output packet to a first pseudo-wire segment.
