A framework for differential frame-based matching algorithms in input-queued switches
Andrea G. Bianco, Paolo Giaccone, Emilio Leonardi, F. Neri · 2005
We propose a novel framework to solve the problem of scheduling packets in high-speed input-queued switches with frame-based control. Our approach is based on the application of game theory concepts. We define a flexible scheduling policy, named SSB (slot sell and buy): the existence of a unique Nash equilibrium for the policy is proved, together with properties of convergence of these equilibria. These findings allows us to state that our SSB scheduling policy achieves 100% throughput both in isolated input-queued switches arid in networks of input-queued switches. Simulation results are used to further validate the approach and to show its flexibility in dealing with differentiated QoS guarantees.
