Abstract
A form of multicast, referred to as 'on-demand multicast,' provides a methodology that allows for 'on demand' multicasting of data. On-demand multicast allows clients to join or leave a transmission at any point. There is no transmission session start or end time—the session is continuously available, although data is not necessarily continuously transmitted. Data blocks missed by late-joining clients are retransmitted per amalgamated client requests through multiple transmission cycles until all clients that have joined the transmission session receive all content. Once a client has received all data blocks comprising the content for the session, the client may exit the ongoing session.
