New scheduling mechanisms for achieving fairness criteria (MCR plus equal share, maximum of MCR or Max-Min share)

The ATM Forum specifies several fairness criteria, thus the scheduling mechanisms should allocate enough bandwidth to each connection to achieve one of such fairness criteria. However, two fairness criteria (MCR plus equal share, maximum of MCR or Max-Min share) cannot be achieved by conventional scheduling mechanisms. In this letter, we have developed new scheduling mechanisms that achieve these fairness criteria. We also present simulation results to show that our mechanisms can allocate bandwidth fairly.
