US Patent 7821928 Method for multiplexing different bit rate sources

This invention relates to the multiplexing of multiple sources in a multiplexer. A special arrangement is used for calculating an efficient peak capacity value that guarantees good performance for an outgoing link. The invention uses a method with two phases. The first phase precalculates the capacity of the outgoing link with different numbers of incoming links having equal packet size, and forms a table from the results of the precalculation. In the second phase, the peak capacity needed for the outgoing link is calculated using the precalculated tables.
