Problem statement: Multimedia Conferencing System (MCS) is a server-based video conferencing system. One of the most critical limit ations faced by this approach is the scalability is sue. In the MCS, the outgoing bandwidth of the server is shared among all concurrent clients. Thus, the mor e clients there are, the lesser the bandwidth each cl ient can have. The performance of this approach therefore deteriorates rapidly as the number of sim ultaneous clients increases. In addition, a pure se rver- based solution is expensive. Approach: In this research, the server-based infrastructure is modified into a peer-to-peer video conferencing system while preser ving the same functionality and features of the existing MCS. This modification can be achieved using a hybrid content distribution model, which is a combination of fluid and chunk content distribution models to distribute parts of the video stream fai rly among participants. The hybrid content distribution model offers a better way of handling heterogeneou s networks because it can distinguish between a fast peer and a slow peer, dealing with each one accordi ng to its capabilities. Results: In our proposed system, the function server will n ot be used for video distribution. Instead, it will only be used for mon itoring and controlling the peers to reduce the bur den on the servers. Experimental results conducted in the nation advanced IPv6 center as a real environment a nd live conferencing. Conclusion: This will lead to overcome the problem of scalabil ity and a bandwidth bottleneck on the main server and achieve good way to distribute video chunks. |
