摘要：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. The solution proposed to solve the above problem is to provide individualized service to each receiver and also it focuses on constructing and maintaining an efficient overlay multicast tree structure. The tree maintenance process is governed by two schemes called as timely reconfiguration and less frequent tree maintenance by state change observation of network. In this paper new scalable architecture is constructed and analyzed based on the above strategies
