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 (ATM) 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 the one set of weights used in traditional schemes, active fairness maintains two sets of weights at each link. The first set is the same as that used in traditional schemes, which represents the relative bandwidth allocation desired out of the available bandwidth at the link. If these weights are used directly in bandwidth allocation, the actual proportion of the bandwidth utilized by an individual connection can deviate substantially due to factors such as the number of links traversed by the connection, its round trip proportion delay, etc. In order to take into account these factors, another set of weights is derived at each link, which is used in bandwidth allocation. Simulations with VCs traversing different numbers of hops have shown marked improvement in fairness.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

Sai, Shankaramma Shivaprasad","doi":"10.1109/ATM.1999.786903","DOIUrl":"https://doi.org/10.1109/ATM.1999.786903","url":null,"abstract":"This paper studies the optimal service schedule of CBR traffic when the server rate is modelled according to a Markov process. The CBR traffic is mixed with traffic of another session (interfering traffic) which might be either CBR or VBR (variable bit rate) or both. The CBR traffic can suffer a maximum delay of T. The scheduler must decide which session must be scheduled for service based on future server rate, estimated from the currently available information. The objective of this paper is to find an optimal time t/sub s/<T for switching the service from interfering traffic to CBR traffic. This switching of the scheduler from one traffic to another traffic takes into account the stochastic variation of the server rate. Three cases of variation of the source rate are considered, namely: (1) when the server rate is a constant; (2) when the server rate jumps randomly between two values; and (3) when the variation of server rate follows a diffusion process. In all three cases, this paper shows that there exists an optimal switching time t/sub s/ after which the low-priority CBR traffic can be scheduled for service. The maximum delay and the cell loss rate are determined.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.
