摘要： Multicast packets that are received on a port of a network device and forwarded to multiple output ports are stored in memory and respective primary control entries which define them are converted to secondary control entries defining multiple unicast packets before a scheduling algorithm is applied. The packets are reconstituted after the application of the scheduling algorithm has been applied to the control entries. For VPLS packets that are received on a single port and replicated multiple times on one or more output ports, a replication database may be used in conjunction with a replication engine to convert the control entry for a received packet into multiple control entries defining unicast packets for each of the destination ports before the scheduling algorithm is applied. This method is applicable to the replication of packets onto a Virtual Private LAN.

摘要： According to one general aspect, an apparatus may include a plurality of ports, a port forwarding processor, and a queue controller. In some embodiments, the plurality of ports may be configured to receive and forward packets within a communications network. In various embodiments, the port forwarding processor may be configured to determine a destination port associated with a received packet. In one embodiment, the queue controller may be configured to define at least one emulated local area network (ELAN) via a respective service member set that identifies which ports are members of the service member set, determine whether or not the destination port is a permitted member of the service member set, and, if the destination port associated with the received packet is not a permitted member of the service member set, flood the received packet to the permitted members of the service member set.
