Multicasting is the process of sending the information to multiple destinations. This technology is highly efficient for delivering the large scale multimedia content where the end receivers have identical needs and similar set of system components. But in reality, the end users have heterogeneous set of requirements for different service levels as well as different service components. The ability to provide differentiated services to user with widely varying requirements is difficult and becoming increasingly important. ISP's are looking forward to find solution for providing Differentiated Services above the existing shared network infrastructure.
