Abstract:
In one embodiment, a local content hub device in a network receives content for distribution to a plurality of nodes in the network. The content is sent to the local content hub via a wide area network (WAN) using bit index explicit replication (BIER) messaging. The local content hub device caches the content and multicasts the cached content to the plurality of nodes in the network. The local content device determines that at least one of the plurality of nodes in the network did not receive the multicast content. The local content device retransmits the content to at least one of the plurality of nodes in the network that did not receive the multicast content.
