Abstract

Embedded devices, such as home routers and single-board computers, are becoming more powerful and affordable. Many of the existing Linux-based network measurement tools can also be run on these devices through cross-compilation. These features provide more incentive for network administrators and researchers to employ them as network measurement probes. Large-scale measurement projects, such as BISMark and RIPE, have already deployed more than hundreds of these devices to measure the Internet from the edge. Our previous work shows that these embedded devices have much lower packet send-Time accuracy compared to commodity PC. The lower accuracy limits their ability to acquire sound measurement results in high-speed networks. In this poster, we present an automated testbed to system-atically benchmark the performance of four popular embed-ded devices (Raspberry Pi I & II, ECS LIVA, and TP-LINK Travel Router) and determine the network types that they can accurately measure. We employ OMware, a kernel-space module, to measure their performance in the testbed. The results can be visualized through a web interface, thus en-abling users to compare various devices easily.
