| Abstract | Multicasting is efficient way of transmitting data from a sender to a group of receivers. A single source or group of source nodes sends identical messages simultaneously to multiple destination nodes. A single rate of multicast transmission per session is likely to either overwhelm the slow receivers or starve the fast ones. Multirate multicast transmission is a proper way to figure out the unfair between the slowest one and the fast ones per session. The main advantage of a multirate scheme is that receivers with different needs can be served at a rate closer to their needs rather than having to match the speed of the slowest receiver. Among two types of approach to multirate data transmission, layered multicast version is preferred in this research work and in congestion control for layered multicast flows join consecutive upper layers and leave recent subscription layers. This research work focuses on a simple multilayer multicast congestion control in the heterogeneous network. The multirate congestion control proposed in this research study named PMCC (Proposed Multirate Congestion Control) modifies TFMCC (TCP-Friendly Multicast Congestion Control) that uses minimum acceptable receiver rate to flawless multicast traffic and achieves good fairness compared to unicast TCP (Transport Control Protocol) traffic, with combining layering scheme of Binary Counting Layers (BCLs) that uses additive increase join attempt mechanism to solve frequently join problem of layered multicast data communication network. Simulation results show that PMCC can fairly share network links to fundamental unicast TCP traffic while they have different bandwidth capacities, different link delays, and different queue lengths. When the number of hops in routing varies the fairness of PMCC remains varies between 0.8 and 1.4. |
