Abstract
Some applications that cannot operate over a non-reliable delivery service may operate sufficiently well over less than a completely guaranteed delivery service. Such an application may perform relatively well even if some transmitted data is not delivered, as long as the application has information regarding which receiving entities received what part of the data. In a point-to-multipoint system, data may be transmitted from a source node to a plurality of destination nodes using a plurality of multicast datagrams. Methods are presented herein for efficiently enabling the source node to determine for each of the plurality of destination nodes which multicast datagrams were successfully received. Also presented are methods for compressing data transmitted from the source node to the destination nodes, wherein a compression dictionary is transmitted from the source node to the destination node using multicast datagrams.
