METHOD AND APPARATUS FOR ADAPTIVE BUFFER MANAGEMENT IN COMMUNICATION SYSTEMS

摘要

PURPOSE: An adaptive method of managing a buffer of a communication system and device thereof are provided to compare previously determine queue length critical value and a queue length value of a monitored buffer in every measuring point and control a queue length critical value according to the compared result. CONSTITUTION: A controller(605) determines a logical area including a current queue length among logical areas. If the current queue length is included in a first queue length corresponding to a first logical area exceeding the upper critical value, the controller detects a congestion state of a network. The controller readjusts the first queue length. A transmitter(620) transmits a network mixing state signal expressing the mixing state of the detected network to an upper network node.
