Abstract: Methods and systems are described to store and forward multicast traffic. The method includes receiving a request to add a first node to a membership tree including a first plurality of nodes associated with a multicast group, identifying a second node in the first plurality of nodes, communicating a node identifier that identifies the first node over a network to the second node where the node identifier is stored at the second node to add the first node to the membership tree where the node identifier is stored in the membership tree to enable the second node to forward multicast traffic to the first node, and where the first and second nodes are separated from each other by at least one other node of the first plurality of node. The first node can be associated with a multicast member that has been added to the multicast group. Other embodiments are disclosed.

Abstract: Methods and apparatus for processing data using sequential dependencies are disclosed herein. An example method includes modifying a first number of values in a sequence of a data set to generate a modified sequence such that each difference between each successive pair of values is within a threshold. A satisfiability metric is determined for the modified sequence based on a relationship between a number of modifications to the values in the sequence and a size of the sequence.

Abstract: A method of receiving content includes joining an in-progress multicast stream to receive a first portion of a content. The method further includes sending a request to a peer for a catch-up portion of the content, the request including a deadline for delivery of the content, and receiving the catch-up portion of the content from the peer prior to the deadline.
