ETHERNET OVER MPLS CIRCUIT EMULATION SERVICE
A method and apparatus are provided for providing CES using both Ethernet and MPLS networks. TDM data is packetized and Ethernet encapsulated, and then MPLS encapsulated. Following insertion into an MPLS core network, the packet is routed to a destination MPLS router using MPLS routing. The MPLS encapsulation is then removed, and the resulting Ethernet frame inserted into a destination Ethernet network. The Ethernet frame is routed to a destination Ethernet port using Ethernet routing. The TDM data is extracted, and inserted into the appropriate TDM channel. The invention allows inexpensive Ethernet equipment to be used at the boundary with the TDM network, and a reliable MPLS network with its QoS functionality to be used for any long-haul part of the CES.
