PALACIOS, Raúl H. et al. Congestion control mechanism for data transfers in multiple Multicast. RISTI [online]. 2018, n.30, pp.62-77. ISSN 1646-9895.  https://doi.org/10.17013/risti.30.62-77.

Currently, it is common to share a lot of information between systems and congestion control mechanisms are essential to avoid saturation in data networks. Although different mechanisms have been proposed, current research follows a focus on this area of science. In this paper, we propose a window-based congestion control mechanism for data transfers in multiple multicast scenarios. The main purpose of the proposed algorithm is to avoid packet loss maintaining a balance in the sending rate of senders. In addition, the algorithm continually analyzes the state of the saturation of the switch and of the receiver nodes considering the storage technology used. Analysis and experiments show that a considerably high network bandwidth is achieved, retransmission of lost packets is avoided as much as possible, even though there is additional network traffic in the test system.
