Abstract:
In an ATM network, a method of regulating telecommunications traffic that is classified in two or more classes of connections by service rates in which class cell buffers are sampled for transmission downstream comprising steps of:counting cyclic time in units of cell transfer period, the cyclic time being expressed in a k-bit word and the counting cycle of length 2.sup.k cell periods being longer than the sampling interval of any class;initializing class accumulators by sampling intervals for the classes, each sampling interval being expressed as an m-bit word, m being larger than k, the most-significant k bits of 854 m bits representing an integer multiple of a cell period and the remaining (m-k) bits representing a fraction of a cell period;declaring a class eligible for service when the value of the most-significant k bits of its accumulator equals the cyclic timeadding class' sampling interval to the content of the class accumulator when a class is declared eligible for service; andperforming the above steps in parallel for all classes so that each class may be declared eligible for service independently from other classes.
