Checking the Accuracy of Siitperf

Abstract

Siitperf is the world’s first free software RFC 8219 compliant SIIT (Stateless IP/ICMP Translation, also called as Stateless NAT64) tester, which implements throughput, frame loss rate, latency and packet delay variation tests. In this paper, we show that the reliability of its results mainly depends on the accuracy of the timing of its frame sender algorithm. We also investigate the effect of Ethernet flow control on the measurement results. Siitperf is calibrated by the comparison of its results with that of a commercial network performance tester, when both of them are used for determining the throughput of the IPv4 routing of the Linux kernel.

A Comprehensive Survey on the Most Important IPv4aaS IPv6 Transition Technologies, their Implementations and Performance Analysis

“…The analysis and based on three different scenarios (IPv4, IPv6, and Moving toward benchmarking methodologies and tools, siitperf is "an RFC 8219 compliant SIIT (stateless NAT64) tester written in C++ using DPDK" [35]. The accuracy of siitperf is examined in [36], by structuring an error model and discussing what could influence the measurements and cause inaccuracy, observing the effect of Ethernet flow-control, concluding that calibrating siitperf is a necessity.…”
