Peer-assisted network operator-friendly P2P traffic control technique

In the existing network operator-friendly traffic control techniques, the network operator provides network information as a guidance to the peers so that the P2P traffic flows as it intends, thus, realizing unilateral interaction from the network operator to the peers. In this paper, we propose bilateral cooperation between the network operator and the peers, in short BiCo. In BiCo, both parties participate in the P2P traffic control actively to improve a network efficiency while solving the identified limitations of existing work. In a nutshell, we divide measurement work into two parts, letting the peers collect finegrained traffic information and enabling the network operator to grasp macroscopic information in order to issue useful guidances (including allowable traffic volume missing in the existing work). Our simulation results show that BiCo improves the network efficiency by distributing the traffic evenly over intra-domain links and by trying to fully utilize inter-domain links with given constraints while showing similar download completion time compared to the existing unilateral interaction.
