Systems and methods for point to multipoint communication in networks using hybrid network devices

摘要

An information handling system is provided. The information handling system includes an ingress network device receiving a multicast stream from a coupled source device and a first and a second egress network device. The first and second egress network devices each receive the multicast stream for coupled destination devices. The information handling system also includes a plurality of intermediate network devices by which the ingress network device is coupled to the first and second egress network devices to form a network and further includes a network controller. The network controller has a topology of the network in a memory and forms a multicast tree based on the topology as well as a link load level and a multicast replication capacity associated with links to the first and second egress network devices and to each of the plurality of intermediate network devices.

主权项

1. A network device comprising:
one or more processors; a network agent running on the one or more processors; a plurality of interfaces in communication with the one or more processors; and a memory, the memory storing instructions that, when executed by the one or more processors, cause a switch to perform a method comprising: sending a multicast replication capacity value to a network controller; receiving labels from the network controller, the labels corresponding to a label-switched multicast tree; and directing packets according to the label-switched multicast tree when sending packets on the plurality of interfaces; and replicating a multicast stream for transmission on at least two of the plurality of interfaces when the network device is designated as a replication point in the label-switched multicast tree.
