Abstract: A network node that includes a memory to store a multicast forwarding table that contains entries that govern how multicast traffic is to be forwarded from a multicast virtual local area network (MVLAN) associated with the network node, to receiver VLANs associated with the network node, where each entry includes a multicast group, that is associated with a group of ports on the multicast VLAN via which the multicast traffic is received, and information associated with the receiver VLANs to which the received multicast traffic is to be sent. The network node also includes a processor to receive multicast traffic associated with a particular multicast group, via a particular port on the multicast VLAN; perform, using the multicast forwarding table, a look up operation, based on the particular multicast group, to determine to which of the receiver VLANs the multicast traffic is to be sent; and transmit the multicast traffic, associated with the particular multicast group, to user devices, via the receiver VLANs, based on a determination that the entry, associated with the particular multicast group, includes information associated with the receiver VLANs.

Abstract translation: 一种网络节点，包括存储器，用于存储组播转发表，所述组播转发表包含控制如何将组播流量从与所述网络节点相关联的组播虚拟局域网（MVLAN）转发到与所述网络节点相关联的接收者VLAN的条目， 其中每个条目包括多播组，其与接收到组播流量的组播VLAN上的一组端口相关联，以及与要接收的组播流量将被发送到的接收者VLAN相关联的信息。 网络节点还包括经由多播VLAN上的特定端口接收与特定多播组相关联的多播流量的处理器; 使用组播转发表执行基于特定组播组的查找操作，确定要向其发送组播流量的哪个接收者VLAN; 并且基于与所述特定多播组相关联的条目包括与所述接收者VLAN相关联的信息的确定，经由所述接收者VLAN将与所述特定多播组相关联的所述多播流量发送到用户设备。
