Abstract

Over the years, in attempts to overcome client-server based limitations, a variety of Peer-to-Peer (P2P) technologies have been developed. This feature can contribute to robustness and scalability. However, it introduces network-oblivious traffic because of network-unaware peer selection. As P2P users have increased, so does the damage this problem causes. To solve this problem, various P2P model based on collaboration between ISP and P2P users have been recently suggested and then reduced network-oblivious traffic by removing biased peer selection. However, previous schemes have mainly focused on reducing traffic, which does improve network performance. In order to support effective real-time IPTV services, it should be required to not only reduce network-oblivious traffic, but it should also improve user performance such as delay and jitter because IPTV is an application sensitive to delay and jitter. In fact, the reduction of network-oblivious traffic improves user performance but it cannot always guarantee optimum performance experienced by real-time streaming service users. In this paper, we propose an ISP-driven managed P2P framework and peer selection mechanism for real-time IPTV user. For the evaluation, we use a QualNet 4.0 simulator and show proposed mechanism provides the performance effectively. Ultimately, we confirmed that ISPs should reflect the delay information of organized P2P network as well as the link traffic between each peer for effective real-time IPTV services.
