Abstract

Abstract: In this paper, we study Distributed Admission Control (DAC) procedure for anycast flows with QoS requirements. We focus on algorithms that perform destination selection, which is critical in anycast. Several algorithms are proposed. These algorithms differ from each other in their dependence on system status information. We also address the issue of resource reservation and re-trial control in the DAC procedure. Performance data obtained by mathematical analysis and computer simulation show that in terms of admission probabilities, DAC systems that are based on local status information can perform closely to those that utilize global and dynamic status information. We note that the latter is much more expensive and difficult to realize.
