摘要:Congestion generally occurs when the amount of packets arriving at the router buffer exceeds the available resources. This causes several problems, such as, increase in the probability of high queuing delay in the buffer, and increase in the probability of losing packets of the buffer. Congestion control method is one of the key that keeps any network efficient and reliable for the users. Many researchers were proposed in the literature over theses years for the efficient control of congestion that occur in the network. The congestion is monitored and controlled at an early stage before the router overflows, using a set of parameters. These methods are formally referred to as Active Queue Management (AQM) methods, which were proposed to overcome the congestion. These methods depend on maintaining the router buffer dynamic. When the packets arrival increases, the amount of packets dropped increases to prevent the accumulation of packets and to maintain the stability of the buffer. This procedure is implemented by assigning a fixed value at which the aql should be maintained. Packet dropping begins before the buffer overflows in reference to the fixed value and the current value of aql. Although such methods perform well in steady buffer, they do not adapt well when aql changes over time. In this paper, In this paper an comprehensive survey is made on the AQM methods that are proposed and the values and short tumbles is existing.
