OSNT: Open Source Network Tester

Abstract : Despite network monitoring and testing being critical for computer networks, current solutions are both extremely expensive and inflexible. Into this lacuna we launch the Open Source Network Tester (OSNT), a fully open-source traffic generator and capture system. Our prototype implementation on the NetFPGA-10G supports 4×10Gbps traffic generation across all packet sizes and traffic capture is supported up to 2×10Gbps with na¨ıvena¨ıve host software. Our system implementation provides methods for scaling and coordinating multiple generator/capture systems and supports 6.25ns timestamp resolution with clock drift and phase coordination maintained by a GPS input. Additionally, our approach has demonstrated lower-cost than comparable commercial systems while achieving comparable levels of precision and accuracy; all within an open-source framework extensible with new features to support new applications, while permitting validation and review of the implementation.
