This document focuses on the experience of running INT in a geographically distributed testbed spanning three sites and deployed on top of the production NREN networks. Testing is performed by adding an INT header to each packet in medium-capacity UDP flows between the sites. The added INT header contains packet-specific flow and time quantities that are analysed at the destination. The document details the design choices taken, the operational challenges faced and the initial results, which demonstrate the potential for high precision monitoring through the use of INT.
