For various purposes, ISP (Internet service provider) set different packet forwarding priorities for different packet types, which has wide influence on the application performance, the results of measurement tools and the networking troubleshooting process. However, such information is usually not available to end-users. This paper proposes an end-to-end measurement method to infer the forwarding priorities of different packet types based on their measured loss rate difference. Using this method, a configured router within an ISP is discovered in the PlanetLab experiment. The inference result has been confirmed by the related network operator.
