Abstract
A novel fabric switch is provided. The switch includes a tunnel management apparatus that maintains a local inter-switch tunnel and an inter-fabric tunnel. The local inter-switch tunnel facilitates communication to a switch in a local fabric switch. The inter-fabric tunnel facilitates communication to a remote fabric switch. The switch further includes a packet header management apparatus that decapsulates a packet received from the local inter-switch tunnel and encapsulates the packet with a new tunnel header for transmission over the inter-fabric tunnel.
