Abstract
Packet switch operating methods and packet switches receive an Ethernet packet including a customer destination address and select one of a plurality of packet tunnel identifiers based on the customer destination address. The packet switch then modifies the received Ethernet packet by adding the selected packet tunnel identifier and forwards the modified packet to a packet tunnel associated with the selected packet tunnel identifier. Other methods and packet switches receive Ethernet packets including a same service virtual local area network identifier value from a first Ethernet network and forward one of the received Ethernet packets to a second Ethernet network via a first packet tunnel and forward another of the received Ethernet packets to a third Ethernet network via a second packet tunnel. Packet tunnel networks including Ethernet provider networks and edge bridges fully connected by packet tunnels having two endpoints.
