Abstract

Multimedia data has special requirements that are hard to be met on mobile hosts due to potentially low bandwidth and disruption due to host mobility. Such limited communication capabilities of mobile hosts can be offset by the simultaneous use of multiple link layer technologies. MMTP is a member of a suite of protocols that share the novel characteristic of aggregating bandwidth from multiple link-layer channels. The use of multiple channels to transport user data provides five key benefits: (1) a fatter pipe,(2) a fast feedback path, (3) the retransmission of selected lost messages, without delaying the playout of the data stream, (4) less sensitivity to minor bandwidth fluctuations on any one individual channel, and (5) smooth vertical handoffs for active data streams.
