Abstract: | Introducing the concept of /spl alpha/-fairness, which allows for a bounded fairness compromise, so that no source is allocated less than a fraction /spl alpha/ of its fair share, this letter studies tradeoffs between efficiency (utilization, throughput or revenue) and fairness in a general telecommunications network with relation to any fairness criterion. We formulate a linear program that finds the optimal bandwidth allocation by maximizing efficiency subject to /spl alpha/-fairness constraints. This leads to what we call an efficiency-fairness curve, which shows the benefit in efficiency as a function of the extent to which fairness is compromised. |
