Priority based packet forwarding in the network communication through routers is common mechanism now a days. This can have a significant impact on the accuracy of network measurements, the performance of applications and the effectiveness of network troubleshooting procedures. But there is no protocol to provide routing for end-to-end approach for forwarding packets based on priority. In this paper, the authors present an inference tool (end-to-end) approach for priority based packet forwarding inferred from feedback of experience through routers. They evaluated their approach via statistical analysis. It enables users to discover such network policies through measurements of packet losses of different packet types.
