Content Delivery Network (CDN) has become increasingly popular over the past decade with the expectation to provide a better performance and a more scalable, reliable and available content delivery. This can be achieved by delivering the content from caches which are located closer to the end-users than the original server. However, the performance of CDN system is affected by the collaboration among CDN servers. This paper proposes a collaborative caching among CDN servers known as provider oriented hierarchical cooperative content outsourcing (POHC). To highlight the advantages of this propose, a mathematic analytical model is given to compare with the non-cooperative pull-based content outsourcing (Non-CPB). OMNeT++ software is used for simulation in order to verify the result of the analytical model. The consequence from the analytical model matched well with the result from the simulative experiment in term of packet loss, better reliability and less bandwidth consumption versus the Non-CPB mode. After collecting relevant status of all CDN servers in online network, this paper uses DBSPT-Circular-PO algorithm to build POHC with root, which is the content provider.
