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.

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

An Ethernet switching and forwarding method, and at least one Ethernet forwarding mode of standard Ethernet forwarding, multiplex Ethernet forwarding, layer-3 routing and forwarding, across-VLAN multicast forwarding plane, point-to-point VLAN forwarding, or point-to-point double VLAN forwarding. The method includes: an Ethernet message entering a user side port or a network side port; processing, by the port, the message to provide the message with a VLAN tag allocated uniformly by the port; determining, by the port, a forwarding mode for the message and sending the message to a corresponding forwarding plane; determining, by the forwarding plane, an egress port of the message and processing the specific Ethernet control message in accordance with a control message capturing policy table; and forwarding the message to the egress port and encapsulating the message in accordance with an attribute table of the egress port.

Ethernet switching and forwarding method, system and apparatus

A method, a system and an access device for implementing error correction are disclosed. The method includes upon receiving a data stream, identifying, by an access device, the data stream on which a forward error correction (FEC) needs to be performed and performing FEC coding on the data stream, and then sending out an FEC data stream generated by FEC coding together with a raw data stream, or sending out directly a data stream on which the FEC does not need to be performed. The system includes a data source for sending out a data stream and an access device for receiving the data stream from the data source, identifying the data stream on which a FEC needs to be performed, performing FEC coding on the data stream, and then sending out an FEC data stream generated by FEC coding together with a raw data stream, or sending out directly a data stream on which the FEC does not need to be performed. The bandwidth can be saved when the FEC is performed in data stream transmission, and it can be adapted to conditions of different access lines according to the invention.

Method, system, and access device for implementing error correction

The present invention relates to a method for accessing integrated services by an access network, including: establishing at least one Multi-Protocol Label Switching (MPLS) Label Switch Path (LSP) in a broadband access network; MPLS encapsulating at a broadband access node a service to be transmitted, and transmitting the encapsulated service in the broadband access network via the LSP. As MPLS is a technology for providing multi-layered connection, in the embodiments of the present invention, MPLS is utilized as the means for networking of broadband access network and private line passing through the core network, so that the problem faced by the broadband access network serving as the bearer network of integrated services can be solved, the integrated services of video, voice, data and private line (including IP private line, and traditional private lines of ATM (Asynchronous Transfer Mode), TDM (Time Division Multiplexing) and FR (Frame Relay)) can be carried over the broadband access network at a lower cost.
