A Novel Dynamic Overlay Routing Mechanism Based on Real-Time Probing Measurements

Recent studies on overlay networks have shown that non-default paths can provide dramatically large performance benefits compared to default ones. In the present paper, we propose a dynamic overlay routing mechanism which chooses paths based on a composite metric determined by actively probed delay and jitter information in a real-time fashion. The effectiveness of this mechanism is examined under overlay emulation environment, which is supported by the performance data collected from a real enterprise overlay network.
