Multicast distribution over one or more addressable buses wherein a switch includes a remapping table for inputting address for one or more destinations

摘要

Disclosed herein is a method for multicasting data to a plurality of destinations over an addressable bus using a switch adapted to receive a stream of data cells from a data source. The switch is adapted to determine the appropriate recipients of the data using a stream identifier associated with the data cells, replicate the data for each destination, and send the replicated data to each destination. The data source need not be aware of the recipient of the data stream because the recipient is determined by the switch. The stream from the data source can be sent to a different set of recipients by associating the new recipients with the stream identifier. This method is useful for applications such as videoconferencing, in which groups of recipients of a particular data stream change often.
