20120014386 | Delegate Gateways and Proxy for Target Hosts in Large Layer 2 and Address Resolution with Duplicated Internet Protocol Addresses - An apparatus comprising a plurality of district boundary bridges (DBBs) in a plurality of second network districts configured to couple to a plurality of core bridges in a core network district and to a plurality of end-stations in the second network districts via a plurality of intermediate switches in the second network districts; wherein the core bridges and the DBBs are aware of a plurality of Media Access Control (MAC) addresses of the DBBs but are not aware of Internet Protocol (IP) addresses and MAC addresses of the end-stations, and wherein the IP addresses of the end-stations are mapped in a directory service (DS) in the core network district to the MAC addresses of the corresponding DBBs in the corresponding second network districts of the end-stations. | 01-19-2012 |
20120275301 | Port and Priority Based Flow Control Mechanism for Lossless Ethernet - An apparatus comprising an aggregation/core switch configure to couple to an edge switch and receive information about a plurality of end system facing ports of the edge switch, wherein the information about the end system facing ports is used to associate the end system facing ports with a plurality of corresponding queues at the aggregation/core switch. Also disclosed is a network component comprising a receiver configured to receive information about a plurality of end system facing ports of an edge switch, a processor configured to establish and associate the end system facing ports with a plurality of corresponding queues, and a transmitter configured to return information about the associated end system facing ports. | 11-01-2012 |
20120275339 | Method and System of Centralized Control and Management for Fiber Channel Over Ethernet Networks - A method implemented in an FCoE controller and manager (FCM) coupled to a first fiber channel over Ethernet (FCoE) data forwarder (FDF), the method comprising sending to the first FDF a first Controlling FDF Information (CFI) request that requests the name of the first FDF, receiving from the first FDF a first CFI acceptance comprising the name of the first FDF, receiving from the first the second CFI acceptance associated with a second FDF, wherein the first CFI acceptance and the second CFI acceptance allow the FCM to develop topology information for a FCoE network comprising the FCM, the first FDF, and the second FDF, creating a first base forwarding table for the first FDF, and creating a second base forwarding table for the second FDF, wherein the second base forwarding table is different than the first base forwarding table. | 11-01-2012 |
20120275467 | Method and System of Centralized Control and Management for Fiber Channel Over Ethernet Networks - A first fiber channel over Ethernet (FCoE) data forwarder (FDF), comprising a memory coupled to a processor, wherein the memory comprises instructions that cause the processor to receive a base forwarding table from an FCoE controller and manager (FCM), wherein the FDF comprise a plurality of ports, and wherein the first FDF uses the base forwarding table to determine which of the ports to send a first FCoE data frame comprising fiber channel (FC) data, receive a second FCoE data frame comprising a media access control (MAC) address, a port identifier, and FC data, and update the base forwarding table using the MAC address and the port identifier. | 11-01-2012 |
20120275787 | Method and System of Centralized Control and Management for Fiber Channel Over Ethernet Networks - A fiber channel over Ethernet (FCoE) network component, comprising a first FCoE data forwarder (FDF) configured to couple to a second FDF and to a third FDF, wherein the first FDF is configured to receive a FCoE frame from the second FDF and send the FCoE frame to the third FDF, wherein the frame comprises a destination address and a fiber channel (FC) payload, and wherein the first FDF does not change the destination address of the frame when the first FDF forwards the frame to the third FDF. | 11-01-2012 |
20130148663 | Method to Carry FCoE Frames Over A TRILL Based Network - An apparatus for forwarding an Fiber Channel over Ethernet (FCoE) data frame into an Ethernet network comprising a processor configured to receive a data frame on a input port, obtain a first destination address and a virtual local area network identifier (VID), determine whether the first destination address and the VID matches an entry within a forwarding table, construct a key when the first destination address and VID matches the entry and the data frame is a FCoE frame, and forward the data frame as an outgoing data frame via an output port when the key matches a rule that permits forwarding the data frame. | 06-13-2013 |
