Application of an Ethernet/MPLS half bridge to provide emulated Ethernet LAN functions in SONET networks

摘要

A system and method for providing emulated Ethernet LAN functions in a SONET network are provided. In one embodiment, a virtual private network includes a core network. The core network includes a shared label switching over SONET network. A plurality of Virtual Local Access Networks (VLANs) are each coupled to a Multiservice Provision Platform (MSPP) of the SONET network. Each VLANs communicates traffic with a corresponding MSPP utilizing Ethernet. The MSPPs interface the VLANs with the SONET network.
