Fair bandwidth share using flow number estimation

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 a 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 number 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 detailed simulations, FNE is proven to provide fairness.
