1. A method, comprising:

  • receiving a fibre channel frame at a first gateway connecting a first fibre channel network to an Internet Protocol (IP) network;

    identifying an incoming label associated with the fibre channel frame, the incoming label determined using fibre channel routing mechanisms;

    swapping the incoming label associated with the fibre channel frame with an outgoing label, the outgoing label determined by referencing an entry in a label information base associated with the first gateway;

    inserting additional labels into the fibre channel frame to establish a tunnel between the first gateway and a second gateway, the additional labels determined using Internet Protocol (IP) routing mechanisms and used to forward the fibre channel frame in the IP network to the second gateway, the second gateway connecting the IP network to a second fibre channel network;

    inserting a control word into the fibre channel frame, the control word used to reorder frames received out of order at the second gateway.
