Abstract
An optimal multiplexing method is disclosed which allows buffers to be two packets in depth. For a plurality of buffers, with each buffer associated with a packetized data stream, packets are received at respective buffer input rates. The buffers are serviced at a service rate at least equal to a sum of the buffer input rates. For each buffer, once a full packet has been received therein, a time interval until that buffer is expected to reach its buffer depth is determined. The buffer having the least time interval is then serviced first, such that overflow of the buffers is avoided.
