Fair bandwidth share using flow number estimation

In this paper, we propose a novel active queue management mechanism, called Flow Number Estimation (FNE), which is able to achieve network fair bandwidth share and tolerate burst traffic. FNE manages the length of FIFO queue effectively and guarantees a reasonable queuing delay for every flow. The feature of traffic regulated by FNE is similar to that by the per-flow fair queuing mechanisms. FNE can support a large amount of flows using hashing function sorting. However, FNE is much simpler than the per-flow fair queuing mechanisms and it can be easily implemented. Through the detail simulations, FNE is proven to provide the fairness.
