AB  - Internet deploy new applications, such as voice over IP, video conference, video streaming, audio streaming, mission-critical financial data, employ the User Datagram Protocol (UDP) and have different requirements on the bandwidth from those of existing applications using Transmission Control Protocol (TCP). TCP-friendliness and multimedia-friendliness "contradict" with each other. The possible approaches to address these problems are to enhance the Internet with resource reservation, admission control and adopt source adaptation schemes such that the sending rate of an application is adjusted according to the current network condition. The source adaptation scheme, better preferred has 2 drawbacks i.e., it is more moderately responsive to transient changes in congestion, including a slower response to an abrupt change in the available bandwidth and the requirement of multimedia applications cannot be satisfied by equation-based source adaptation when a large number of flows share a link. The proposed system, develops a framework which extends the concepts of fairness, TCP-friendliness and TCP-compatibility, by designing TCP and UDP friendly source adaptation schemes and develop a less conservative framework to provide bandwidth differentiation service without any change to the router of the existing Internet. The proposed scheme is extended towards the handling of multiple bottleneck links available in the real time networks. In addition, the scheme combines with TCP slow-start, timeout to provide a relatively differentiated bandwidth service in the existing Internet, without any change to the router. The newly developed source adaptation scheme is improved to work with multiple priority classes.
