A new design of bandwidth shaper with an intra-protocol fairness

In order to allocate proper network bandwidth in an organization, a bandwidth shaper is generally deployed. It helps ensure that the most significant applications have enough bandwidth shares, and users fairly share the bandwidth. However, with the existing of multi-session download accelerator software (such as IDM, Flashget), some users can cheat the bandwidth share even after using the bandwidth shaper. This problem is known as an intra-protocol fairness problem. So, in this paper, we have proposed to improve the bandwidth shaper by two new mechanisms, namely P2P detection and intra-protocol fairness management. Prototyped software has also been implemented and evaluated. Our experimental results on a test-bed have demonstrated the effectiveness of our design to improve the bandwidth shaper.
