Bobby Vandalore, Sonia Fahmy, Raj Jain, Rohit Goyal, Mukul Goyal, "A Definition of General Weighted Fairness and its Support in Explicit Rate Switch Algorithms ," Proceedings of Sixth International Conference on Network Protocols 1998 (ICNP'98), Austin, Texas, October 13-16, 1998, pp. 22-30.

In this paper we give a general definition of weighted fairness and discuss how a pricing policy can be mapped to general weighted (GW) fairness. The GW fairness can be achieved by calculating the ExcessFairshare (weighted fairshare of the left over bandwidth) for each VC. We show how a switch algorithm can be modified to support the GW fairness by using the ExcessFairshare term. We use ERICA+ as an example switch algorithm and show how it can be modified to achieve the general fairness. Simulations results are presented to demonstrate that, the modified switch algorithm achieves GW fairness. An analytical proof for convergence of the modified ERICA+ algorithm is given in the appendix.
