Reducing the variability of the data rates of high-rate data streams in order to communicate such streams over a low-rate channel of fixed capacity

摘要

Techniques whereby a transmitter/receiver pair are cooperatively arranged to buffer incoming data to both the transmitter and the receiver. The transmitter and receiver of the pair are coupled, generically, by pre-existing channel which has a known, fixed capacity. The transmitter/receiver pair exploits whatever delay is permissible, as determined by end-users of the data, for the data stream or streams that are using the channel for the purpose of accommodating periods of excessive instantaneous aggregate data transfer demands. The matched transmitter/receiver pair thereby permits (i) the transmission of a variable rate stream over a channel with capacity less than the peak rate of the stream, or (ii) the multiplexing of variable and/or fixed rate data streams.
