Application Layer Multicast Technology Implementation And Performance Analysis

The traditional IP multicast architecture was proposed for these communication models. However, more than a decade after its initial proposal, deployment of IP multicast has been limited due to a variety of technical and market reasons. Under this condition, IP multicast architecture can't satisfy customers and their application. Researchers in the recent past have proposed application layer multicast as an alternate technique for provide multicast services. The basic idea of application layer multicast is to implement the multicasting functionality at the application layer independent of the support of multicasting functionality in network layer. That means, application layer multicast takes advantages of network resources available at the edge of Internet instead of the core of Internet.The paper introduces some things about IP multicast and Application layer multicast. It also says something about the performance analysis and the methods. Firstly, we analyzed the current development of application layer multicastThe advantage of the Application multicast is not deployed on the router but also on the edge of Internet —Application Layer. So the topology of application layer multicast is dynamic. The paper advances on the stabile status to construct a network topology by the performance of application layer. It has the important significance to settle the network load and server load on the development of multicast.
