Abstract
A method for performing congestion control in a communication system. The method includes transmitting a request message to a node using a first packet with a highest priority and receiving a response message corresponding to the request message using the first packet and at least one of a plurality of second packets, estimating a one-way delay of the first packet according to a round trip time for the first packet, converting one of the one-way delay of the first packet and the one-way delay of at least one of the plurality of second packets into a quality of service (QoS) level using a predetermined upper delay bound for a corresponding packet, and converting the converted QoS level into an effective congestion level representing a congestion degree in a network and performing congestion control using the effective congestion level.
