Abstract: Congestion is necessary concern that can occur within the packet switched network. Here discussion on Congestion control gives the approach and appliances to control the problem of congestion and either avoid congestion from happening or eliminate the congestion once it has taken place. This paper summarizes the different category provided through the congestion control. Here It also discussed on how TCP utilize congestion and manages to improve congestion or avoid congestion in the network. In this paper we proposed that all the activity which we are managing by our proposed scheme is assure about the reliability aspects due to the connection oriented TCP services and the previous working of the “multicast congestion avoidance” (MCA) lower version protocol has been implemented as UDP connection-less services. Hence reliability will be increased significantly.
Keywords: Congesion Control; Congesion Control Algorithm, “Multicast Congestion Avoidance” (MCA).
