Abstract: A method of inverse multiplexing and demultiplexing multiple ATM communication channels. This process is intended to maximize the use of bandwidth on all channels when the bandwidth conditions on each channel are fluctuating dynamically with time. In extreme cases, this method is intended to work even when one or more channels cease to operate. The multiplexing part of this method seeks to maximize the bandwidth along all communication links as well as maintaining a record of the bandwidth fluctuations along the channels. The demultiplexing part of this method seeks to accurately reconstruct the ATM cell stream that was inverse multiplexed across the multiple communication links by ordering the cells in the same order as they were sent. Two processes are presented by which this is done.
