Abstract

The fair distribution of bandwidth to different connections is an important issue in high-speed networks. This is especially true in low-priority services where the bandwidth available for the low priority connections may be small and may vary rapidly. An example is the Available Bit Rate (ABR) service in Asynchronous Transfer Mode networks. This study uses the ABR service to explore a scheme that achieves better fairness in bandwidth allocations. Traditional schemes fail to achieve desired bandwidth allocations, which are generally based on connection weights. In this paper, a new scheme called Active Fairness is proposed which substantially improves fairness in bandwidth allocations. Contrary to one set of weights used in traditional schemes, Active Fairness maintains two sets of weights at each link.
