IP Multicast is a natural extension of the unicast model. Multicast is a powerful service because it allows a single source to reach a virtually unlimited number of receivers in a very efficient and scalable manner. This work is implemented based on the concept of light weight multicast services (LMS). It is an extension to IP multicast that provides scalable and reliable multicast transport services. LMS extends IP multicast with a set of simple and lightweight services that enhance router forwarding for reliable multi casting. LMS cleanly separates the transport and forwarding component of error control by keeping the former at the end points thus avoiding layer violations, and pushes the latter to the routers where it can be implemented more efficiently. In the existing system implementation of single source sending data to destination is considered. In this work implementation of multiple sources sending data to many destinations is considered in this paper remedies to the loss of retransmitted packets are provided.
