Abstract
We describe the design of PSON, an overlay network, which improves the predictability of end-to-end communication latency on the Internet. Predictable Service Overlay Networks (PSON) monitor the paths between overlay nodes and continuously estimates an upper bound on communication latency to provide a soft synchrony guarantee to application. Through network measurements on PlanetLab nodes we observe that the upper bound estimation provides long durations of synchrony and rapidly adjusts the bound in response to an asynchronous event. Upper bound estimation is enhanced by the use of routing and overlay configuration to provide stable routes while reducing overhead. We describe the architecture, design and interface for the PSON and discuss various issues related to its performance.
