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.

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.

Data Transmission Method and Apparatus and Network Element

A method for data transmission includes receiving a packet, determining a first member link in a first group of member links based on a first decision manner. If the first member link is unavailable, the method includes determining a second member link in a second group of member links based on a second decision manner, where all member links in the second group of member links are available and the first group of member links includes the second group of member links and an unavailable member link. The method includes sending the packet through the second member link.
