Claim Text:
1. A method for sending Fibre Channel over Ethernet (FCoE) traffic over an overlay network, the method comprising: receiving a block of media access control (MAC) addresses for use in local fabric initialization protocol (FIP) operations at an overlay-capable virtual switch of a server; communicating with a central controller using the overlay-capable virtual switch; advertising to local FCoE initiators to route FCoE traffic to the server by asserting the overlay-capable virtual switch within the server as a Fibre Channel forwarder (FCF) for requesting FCoE initiators; receiving one or more modified FCoE frames from a converge network adapter (CNA) within the server after destination information in the one or more FCoE frames has been modified to cause the CNA to pass the one or more modified FCoE frames to the overlay-capable virtual switch instead of passing the one or more FCoE frames to a destination address indicated in the one or more FCoE frames; implementing a source virtual tunneling end point (VTEP) in an overlay network; encapsulating the one or more modified FCoE frames with an overlay header, wherein the overlay header comprises routing level information to deliver the one or more modified FCoE frames to a destination VTEP in the overlay network; and sending the one or more modified FCoE frames to the CNA for passing the one or more modified FCoE frames to the destination VTEP.
