Abstract: The Fibre Channel standard was created by the American National Standard for Information Systems (ANSI) X3T11 task group to define a serial I/O channel for interconnecting a number of heterogeneous peripheral devices to computer systems as well as interconnecting the computer systems themselves through optical fiber and copper media at gigabit speeds (i.e., one billion hits per second). Multiple protocols such as SCSI (Small Computer Serial Interface), IP (Internet Protocol), HIPPI, ATM (Asynchronous Transfer Mode) among others can concurrently utilize the same media when mapped over Fibre Channel. A Fibre Channel Fabric is an entity which transmits Fibre Channel frames between connected Node Ports. The Fibre Channel fabric routes the frames based on the destination address as well as other information embedded in the Fibre Channel frame header. Node Ports are attached to the Fibre Channel Fabric through links.

Abstract: Methods, apparatus and systems are provided for assigning Fibre Channel Domain identifiers with an iSNS Server, a Fibre Channel over Ethernet device interconnection apparatus controller (FIAC), and a Fibre Channel over Ethernet device interconnection apparatus (FIA). A Request Domain Identifier iSNS protocol message is sent from a FCoE device interconnection apparatus controller (FIAC) to a iSNS Server. A Fibre Channel Initialization Protocol (FIP) Fabric Login (FLOGI) frame is received from a Fibre Channel over Ethernet (FCoE) device by a FCoE device interconnection apparatus (FIA). The FIAC assigns a new Fibre Channel address identifier using the Domain Identifier assigned from the Request Domain Identifier response. At the FIAC, a FIP link service accept (LS_ACC) response is transmitted to the FIP FLOGI comprising the newly assigned Fibre Channel address identifier at the FIAC. At the FIA, the FIP LS_ACC is forwarded to the FCoE device that transmitted the FIP FLOGI frame.

Abstract: Methods, apparatus and systems are provided for forwarding Fibre Channel over Ethernet (FCoE) frames over a TRILL network by a FCoE device interconnection apparatus (FIA). A FCoE frame is received from a FCoE device at the FIA. The frame includes at least destination Ethernet MAC address and source Ethernet MAC address fields. The destination Ethernet MAC address of the incoming frame is replaced with the MAC address of the remote FCoE device as determined by the Fibre Channel destination address identifier in the received FCoE frame. The source Ethernet MAC address of the incoming frame is replaced. The frame is encapsulated in a TRILL header. The frame is forwarded to an egress FCoE device interconnection apparatus (FIA). The frame is then decapsulated into a FCoE frame, which is forwarded to an attached FCoE device with the original destination and source Ethernet MAC addresses.

Abstract: Methods, apparatus and systems are provided for forwarding Fibre Channel over Ethernet (FCoE) frames over a Shortest Path Bridged network with a FCoE device interconnection apparatus (FIA). A FCoE frame is received from a FCoE device, the frame including at least destination Ethernet MAC address and source Ethernet MAC address fields. The destination Ethernet MAC address of the incoming frame is replaced with the MAC address of the remote FCoE device as determined by the Fibre Channel destination address identifier in the received FCoE frame. The source Ethernet MAC address of the incoming frame is replaced. The frame is encapsulated in a MAC header. The frame is forwarded to an egress FCoE device interconnection apparatus (FIA). Thereafter, the outer MAC header of the received frame is decapsulated into a FCoE frame. The decapsulated frame is forwarded to an attached FCoE device with the original destination and source Ethernet MAC addresses.

Abstract: Methods, apparatus and systems are provided for creating virtual links between Fibre Channel over Ethernet (FCoE) nodes. FIP Discovery Advertisement frames are received from multiple FCoE device interconnection apparatus (FIA). The FIP Discovery Advertisement frames comprises source Ethernet MAC addresses, a destination Ethernet MAC address of All-ENode-MACs, Fabric FIP descriptor, and a Priority FIP descriptor. A list is stored of one or more of the source Ethernet MAC address, FIP Priority descriptor, and FIP Fabric descriptor for each unique FIP Discovery Advertisement frame received as indicated by the Fabric descriptor. The Name Server is queried for each source Ethernet MAC address in said storage. For all FCoE devices that match in more that one Name Server, connect to those FCoE devices using the highest priority Ethernet MAC address from matching list items.

Abstract: Methods, apparatus and systems are provided for processing Fibre Channel Fabric Login frames by a FCoE device interconnection apparatus (FIA) and a FCoE device interconnection apparatus controller (FIAC). A Fabric Login (FLOGI) Fibre Channel frame is encapsulated into a Fibre Channel over Ethernet (FCoE) FIP FLOGI frame at a Fibre Channel device interconnection apparatus (FIA). The encapsulated frame is transmitted from the FIA to a FCoE device interconnection apparatus controller (FIAC). A FIP link service accept (LS_ACC) frame is transmitted by the FIAC to the FIA, and the FIP LS_ACC frame is received by the FIA. The FIP frame is decapsulated into a Fibre Channel LS_ACC frame at the FIA. The Fibre Channel LS_ACC frame is transmitted back to the said Fibre Channel device.

Abstract: Methods, apparatus and systems are provided for forwarding Fibre Channel Initialization Protocol (FIP) and Fibre Channel over Ethernet (FCoE) frames by a FCoE device interconnection apparatus (FIA) and a Fibre Channel over Ethernet device interconnection apparatus controller (FIAC). In one aspect of the invention, a command is sent from a FIAC to the FIA to set the frame processing apparatus to identify received FIP frames, which are forwarded with the original destination and source Ethernet Media Access Control (MAC) addresses. A command is sent from the FIAC to the FIA to identify received FCoE frames to replace the source and destination Ethernet MAC addresses. When a FCoE frame is received by the FIA, the source and destination Ethernet MAC addresses are replaced, such as where the destination Ethernet MAC address of the received matched FCoE frame is replaced by the MAC address assigned to the desired end port. The FCoE frame is forwarded to a destination FCoE device.
