VORRICHTUNG UND VERFAHREN ZUR REGULIERUNG DES ZELLFLUSSES AM ENDE EINES ATM SYSTEMS

An end system cell flow regulator includes a congestion state determiner (208), a data source (202), a cell scheduler (206), and a leaky bucket monitor (204). The congestion state determiner typically decides congestion state based on feedback information and a timer. The data source typically further includes a cell generator, a cell buffer, a cell flow switch and a cell buffer state determiner. The cell scheduler further includes a DCR, Dynamic Cell Rate, determiner and a cell rate determiner, wherein the cell scheduler decides the next cell time for transmission based on the cell buffer state, congestion state and leaky bucket state. The cell rate determiner determines if the cell rate is set to DOR or PCR, Peak Cell Rate, based on the leaky bucket and cell buffer states. The DCR determiner establishes the DCR rate based on congestion state and cell buffer state.
