Towards Trustworthy Network Measurements

End-to-end network measurement tools are gaining increasing importance in many Internet services. These tools were designed, however, without prior security consideration which renders their extracted network estimates questionable, given the current adversarial Internet. In this paper, we highlight the major security vulnerabilities of existing end-to-end measurement tools and we sketch possible avenues to counter these threats by leveraging functionality from the OpenFlow protocol. More specifically, we show that the security of bottleneck bandwidth estimation and RTT latency measurements in network coordinate systems can be strengthened when the network deploys a number of OpenFlow-operated switches.
