摘要： A method may include receiving, at a network interface of a first network element, an Internet Group Management Protocol (IGMP) message from a second network element. The method may also include updating first multicast group data associated with the network interface based on the received IGMP message, the first multicast group data including one or more entries setting forth a multicast group and one or more other network elements which are members of the multicast group. The method may additionally include determining whether the second network element is the sole member of its multicast group based on the IGMP message and the first multicast group data. The method may further include forwarding the IGMP message to a switching element of the first network element in response to determining that the second network element is the sole member of its multicast group, the switching element communicatively coupled to the network interface.

摘要： A network element coupled to a communication network is described. The network element includes multiple switching units. The switching units may be configured to independently implement a Spanning Tree Protocol (xSTP) processing in a completely distributed manner including each of the switching units independently calculating an external spanning tree for the network element in the communication network. The network element may act as a single bridge to other network elements in a bridging domain of the communication network.

摘要： A switch includes a processor coupled to a memory, one or more forwarding tables residing within the memory, and one or more ports. The ports are associated with a plurality of virtual local area networks and a plurality of bridge domains. Each of the bridge domains is associated with one of the forwarding tables, and each of the forwarding tables is associated with one of the bridge domains. The processor is configured to assign a first tag to a received packet, assign a second tag to the received packet, look up the destination address of the received packet in one of the forwarding tables, and selectively flood the ports of the active bridge domain with a copy of the received packet. The active bridge domain includes one of the plurality of bridge domains. The active bridge domain is associated with the ingress port of the received packet.

摘要： In one embodiment, a method for telecommunications includes steps of receiving a first packet through a first port, and determining whether the first packet arrived over a protected path. If the first packet arrived over a protected path, the method also includes the steps of hashing a source address of the first packet, adding a first entry into a forwarding table, and adding a second entry into the forwarding table. The protected path is coupled to at least the first port and a second port. The first entry includes the result of hashing the packet, and an identification of the first port. The second entry includes the result of hashing the packet, and an identification of the second port.
