Fairness criterion for allocating resources ininput queued switches
D. Liu, Nirwan Ansari, E.S.H. Hou · Electronics Letters · 2001
A new fairness criterion, queue proportional fairness (QPF), is proposed. It employs the cell loss ratio as the fairness metric to improve the utilisation of switch resources. QPF provides a fairness criterion for allocating bandwidth by considering the current buffer occupancy for best effort traffic in an input queued switch.
