Content distribution node selection algorithm on hybrid architecture of P4P and CDN
Fuke Shen · Journal of Computer Applications · 2009
Both Content Distributed Network (CDN) based and P2P based architectures have been proposed to distribute data. However,each kind of architecture has its own limitations. By taking advantage of Proactive network Provider Participation for P2P (P4P) which allowed more effective traffic control between applications and network providers,a new hybrid architecture which integrated CDN and P2P based content distribution system was designed,and a content distribution node selection algorithm was given in full details. The algorithm selected the appropriate edge node using network information got from P4P,then contributed its capacity and bandwidth services to other nodes in order to reduce the number of edge prosy servers,increasing the system capacity,while reducing the load of network. Taking into account the circumstances of the underlying network,cost of link and time were tested. The simulation results show that the algorithm reduces the network cost and improves the performance of peers-assisted CDN.
