Research Reviews on Network-based Congestion Control

Congestion control has been considered as a principal technology for efficient end-to-end traffic transmission. Previous studies on congestion control are mainly focused on the control of the transmission rate or window size at the host. However, such host-based congestion controls have difficulties on short time-scale variable network conditions and increased host complexity. To address this problem, network-based congestion controls that utilize network information have been considered which determine and control the congestion using the network information. In this paper, we review the network-based congestion control methods.
