Abstract: A system and method for providing an application of an Ethernet/MPLS half bridge to provide Ethernet multiplexing functions (EMF) in SONET network elements (NEs). In one embodiment, a virtual private network includes a core network. The core network includes a SONET over shared label switching network. A plurality of Virtual Local Access Networks (VLANs) are each coupled to a Multiservice Provisioning Platform (MSPP) of the core network. Each VLAN communicates traffic with a corresponding MSPP utilizing Ethernet over a plurality of Ethernet interfaces. The MSPP interfaces the VLANs with the core network based, in part, on the plurality of Ethernet interfaces.
