ABSTRACT:
To simplify the service decision made in a queue based digital switch, a method and apparatus is introduced that makes service decisions based upon the history of incoming cells. The apparatus includes a minimum service rate circuit that monitors the rate of arriving cells. The minimum service rate circuit tests the arriving cells to determine if they are in conformance with the minimum service rate of a service contract. The minimum service rate circuit may use a continuous state leaky bucket algorithm as specified in the CCITT Recommendation I.371 document, dated 1992, to determine if a cell is in conformance with the minimum service rate of the service contract. When a cell arrives that conforms to the minimum service rate, the minimum service rate circuit notifies the server and the server serves the queue associated with the connection.
