METHOD AND SYSTEM FOR ADAPTIVE RATE MANAGEMENT, FOR ADAPTIVE POINTER MANAGEMENT AND FOR FREQUENCY LOCKED ADAPTIVE POINTER MANAGEMENT

摘要

PROBLEM TO BE SOLVED: To provide an adaptive rate management method and system for adapting a receiver rate to a transmission rate in a packet switched network.

SOLUTION: The method comprising the steps of determining an error value of a sample rate, obtaining an updated accumulator value based on said error value Esat a decimated sample rate, and generating an appropriate rate command and changing said accumulator value at the decimated rate based on the updated accumulator value, may be adapted for either adaptive pointer management or bit stuffing. When applied to adaptive pointer management (APM), the method generates pointer adjustments for rate management. In a frequency locked APM preferred embodiment of the method and system, pointer adjustments in an interval are generated at a constant rate based on an average pointer adjustment value calculated in previous intervals.
