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.

Abstract: In one embodiment, a device in a network sends a first multicast message to a plurality of destinations in the network. The first multicast message includes a first bitmap that identifies the destinations. The device receives one or more acknowledgements from a subset of the destinations. The device determines a retransmission bitmap that identifies those of the plurality of destinations that did not acknowledge the first multicast message, based on the received one or more acknowledgements. The device sends a retransmission multicast message to those of the plurality of destinations that did not acknowledge the first multicast message. The retransmission multicast message includes the retransmission bitmap.

Abstract: In one embodiment, a first node in a network receives one or more bitmaps from one or more child nodes of the first node according to a directed acyclic graph (DAG). Each of the one or more child nodes is associated with a corresponding unique bit position in the one or more bitmaps. The first node stores, in a forwarding table, the one or more bitmaps received from the one or more child nodes of the first node. The first node receives a message that includes a destination bitmap that identifies one or more destinations of the message via one or more set bits at bit positions associated with the one or more child nodes. The first node forwards the message towards the identified one or more destinations based on the destination bitmap and the one or more bitmaps stored in the forwarding table of the first node.

Abstract: An apparatus for facilitating reception of multiple representations of a video signal. In one embodiment, the apparatus includes a mechanism for receiving plural representations of the video signal corresponding to plural decimated versions of the video signal, associating pictures of the received plural representations of the video signal, and outputting pictures corresponding to information from associated pictures in accordance with a relative temporal order.

Abstract: A first sequence of pictures may be partitioned into plural representations, each of the plural representations may be encoded independently of each other with a common time base, a first portion of the plural encoded representations may be provided based on a first network condition, the first portion having a first bit-rate, and a second portion of the plural encoded representations may be provided having a second bit-rate different than the first bit-rate, wherein a switch from providing the first portion to providing the second portion is responsive to a second network condition different than the first network condition.
