摘要： A method, system and controlling bridge (CB) for acquiring port extension (PE) topology information, and a method and system for processing an upstream port, wherein, the method for acquiring the port extension (PE) topology information includes: a CB receiving a link layer discovery protocol (LLDP) message sent by the PE, and perceiving an attachment of the PE; the CB receiving Extended Port Create message sent by the PE, and instantiating corresponding instantiated ports inside the CB. By adopting the above-mentioned technical scheme, the topology information of the PE connected to the CB can be obtained and a channel for forwarding data can be established, effectively.

摘要： The disclosure provides a method and system for implementing a resilient network interface and interconnection. The method includes: aggregating one or multiple aggregation ports on one or multiple nodes into one DLAG; and implementing a distributed resilient network interface by the DLAG. Through the disclosure, the problem that the existing ring network and other protection technologies cannot ensure normal transmission of traffic in an arbitrary network is solved, thereby effectively ensuring normal operation of a service in the network and improving the reliability of the network interface and the utilization rate of the link.

摘要： Disclosed are a multicast data forwarding method and device supporting a virtual terminal. The method includes: a bridge forwarding module receiving multicast data sent by an end station and determining output ports; when a certain output port is the same with the input port of the multicast data and the input port has enabled reflective relay function, not carrying Ingress extended channel identifier (Ingress_E-CID) in the forwarded message information or the value of the Ingress_E-CID being zero. By modifying the source port filtering mechanism, the present invention enables a Port Extender (PE) supporting the virtual terminal technology to transmit and receive data normally while multicasting.
