Enabling Cooperation between ISPs and P2P Systems toward IPTV Service Delivery

The wide adoption of the P2P networks for the deployment of IPTV services at large scale seems very fascinating. However, it has started exposing the other side of canvas that is not acceptable for the provisioning of QoS for P2P applications. It is even more frustrating for the ISPs due to inefficient utilization of network resources. In this paper, we investigate the conflicting objectives of P2P applications & ISPs and we propose a framework enabling better interaction among entities involved in the IPTV service delivery mechanism. This interaction is facilitated by a topology-aware overlay network organization driven by the ISPs that is used to organize the participating peers within the network. The proposed ISPs-driven overlay organization facilitates the multi-attribute based sender peers selection mechanism and thus ensures the efficient utilization of available resources in ISPs domain and guarantees better QoS for the P2P applications. The framework is evaluated using the networks simulations to conform its viability. The obtained results show a noticeable improvement in the received QoS for the P2P applications and enable the efficient utilization of the available network resources to benefit the ISPs.
