Abstract:
Frames of customer traffic may be encapsulated by adding Mac-in-Mac (MiM) encapsulation fields for transportation of the frames over a portion of provider network. The MiM encapsulated traffic may be further encapsulated using VPLS by adding VPLS encapsulation fields for transportation of the frames over another portion of the provider network. The MiM encapsulations use provider network_MAC addresses which enables VPLS MAC learning to occur using provider network MAC address space. MiM tunnels are mapped to VPLS service instances which are assigned pseudowire tags for transportation over the VPLS portion of provider network. The MiM header is retained when the MiM encapsulated frames are transported over the VPLS portion of the provider network. As VPLS frames exit the core network, the VPLS encapsulation fields are removed to extract the original MiM encapsulated frames for further transportation over the MiM portion of the provider network.
