Abstract
A distributed Fiber Channel over Ethernet (FCoE) Forwarder (FCF) and a distributed Fibre Channel Switch are described. The Distributed FCF is realized by instantiating respective connections between at least one Controlling FCF and a plurality of FCoE Data-Plane Forwarder (FDF) devices and between individual FDF devices. The Distributed FC Switch is realized by instantiating respective connections between at least one Controlling Switch and a plurality of FC Data-Plane Forwarder (FCDF) devices and between individual FCDF devices.
Claims20
An apparatus, comprising:
- a Controlling Fibre Channel Switch;
- and
- a plurality of Fibre Channel Data-Plane Forwarder (FCDF) devices in communication with the Controlling Fibre Channel Switch,
- wherein the Controlling Fibre Channel Switch and the plurality of FCDF devices are represented by a single domain identifier.

A method comprising:
- establishing a distributed fibre channel (FC) switch by instantiating respective connections between at least one Controlling Fibre Channel Switch and a plurality of Fibre Channel Data-Plane Forwarder (FCDF) devices in communication with the Controlling Fibre Channel Switch;
- receiving a FC frame addressed to the at least one Controlling Fibre Channel Switch or one of the FCDF devices of the distributed FC switch;
- and
- based on a destination address identifier (D_ID) in the FC frame, forwarding the FC frame to one of a Fibre Channel fabric, to a host that is accessible to the Controlling Fibre Channel Switch or to one of the FCDF devices.
