Abstract
A method and apparatus manage a buffer of a lower network node in a communication system. A current queue length of the buffer is monitored in every measurement time. A logical region in which the current queue length is included is determined, among a plurality of logical regions included in the buffer. Each of the logical regions corresponds to a queue length determined by using an upper threshold and a lower threshold of a total queue length of the buffer. A congestion state of a network is detected, and a first queue length is readjusted when the current queue length is included in the first queue length which corresponds to a first logical region that exceeds the upper threshold. And a network congestion state signal that represents the detected congestion state of the network is transmitted to the upper network node.
