Abstract
Packet switch operating methods and packet switches receive an Ethernet packet from an Ethernet provider network and create a plurality of duplicates of the received Ethernet packet. The methods and switches then modify the duplicates by assign a same service instance identifier and a different packet tunnel identifier to each of the duplicates and then forward the modified duplicates to packet tunnels associated with the packet tunnel identifiers. Other methods and packet switches receive an Ethernet packet including a service instance identifier from a packet tunnel and prevent the received Ethernet packet from being forwarded to another packet tunnel associated with the service instance identifier. Packet tunnel networks including Ethernet provider networks and edge bridges fully connected by packet tunnels. The edge bridges are configured to prevent packets received from one of the tunnels from being forwarded to other tunnels.
