PROTOCOL FOR MULTICAST COMMUNICATION

摘要

A data processing system method and software application program is provided for the efficient dissemination of information to multiple recipients over one or more communication channels in a communications network, for instance the multicast Internetwork. The method defines at least one primary data set for transmission over at least one primary communications channel in the network, where each primary data set includes data relating to at least one secondary data set associated therewith and provided for transmission over a secondary communications channel. The primary data set or sets are transmitted over primary communications channel(s) and at least one primary data set is modified in response to modifications to at least one secondary data set. The transmission step is repeated to provide potential recipient(s) of the primary data set or sets with an indication that at least one secondary data set has been modified independently of the recipient(s) receiving the modified secondary data set or sets.
