  7. Abstract:


  8. IP multicasting, content distribution networks (CDN) and recently P2P streaming systems are the main scalable methods that have been researched. IP multicasting has not been activated in service provider networks due to some fundamental deployment problems and CDNs require the deployment of a large number of servers throughout the Internet. Pure P2P architecture is a more challenging approach for constant quality and continuous video streaming due to the churn nature and limited resource of the Internet peers. Therefore, we design a hybrid architecture for large-scale video streaming applications that combine an infrastructure of CDNs with the P2P network. Unlike previous work, in this architecture the constructed meshes under each CDN server connect gradually together and form a single mesh. We call this architecture connected mesh and compare it with unconnected mesh. We also propose some techniques to improve the pure mesh-based P2P that is used in P2P part of this architecture. Finally, we do performance analysis using the OMNeT++ simulator. The result shows that the proposed architecture, the connected mesh architecture has significant enhancement in end-to-end delay and distortion with higher but tolerable startup delay.
