A Novel QoS Framework Based on Admission Control and Self-Adaptive Bandwidth Reconfiguration

Abstract


This paper proposes a novel end-to-end QoS framework, called Self-Adaptive bandwidth Reconfiguration QoS framework (SAR). SAR provides end-to-end QoS guarantees on a per-flow basis through admission control and end-to-end bandwidth reservation. In order to adapt to short and long time traffic load changing, SAR performs dynamic bandwidth reconfiguration. Due to a new organization of the network physical lines, SAR allows for a better utilization of the links’ capacity and a smaller number of rejected flows, increasing the network’s availability.

Keywords
