Systems and methods for pseudowire-in-pseudowire to transport pseudowire payload across packet switched networks

A pseudowire-in-pseudowire system configured to transport a pseudowire payload across packet switched networks, comprising:

• a first provider edge;
• a second provider edge interconnected to the first provider edge through a multi-protocol label switched network;
• a transport pseudowire configured between the first provider edge and the second provider edge over a tunnel label switched path;
• and
• one or more client pseudowires transported from the first provider edge to the second provider edge, wherein the one or more client pseudowires are transported over the transport pseudowire.

A pseudowire-in-pseudowire network configured to transport a pseudowire payload across packet switched networks, comprising:

• a plurality of terminating provider edges, wherein each of the plurality of terminating provider edges is connected to one of a plurality of multi-label protocol switched networks;
• a plurality of switching provider edges interconnecting the plurality of multi-label protocol switched networks;
• and
• one or more transport pseudowires comprising a layer two Internet Protocol transport pseudowire transported over a tunnel label switched path, wherein each of the one or more transport pseudowires is provisioned between one of:
• a first terminating provider edge of the plurality of terminating provider edges and a second terminating provider edge of the plurality of terminating provider edges;
• and
• a first switching provider edge of the plurality of switching provider edges and a second switching provider edge of the plurality of switching provider edges;
• wherein the one or more transport pseudowires comprise a multi-segment pseudowire;
• and
• wherein each of the one or more transport pseudowires is configured to transport one or more client pseudowires.
