We chose to make detailed measurements from two monitors at SLAC.
The Dell Poweredge 2650 bare metal pinger.slac.stanford.edu server running Red Hat Linux 2.6.32-504.8.1.el6.i686
Code Block pi@pinger-raspberry ~ $ uname -a Linux pinger-raspberry.slac.stanford.edu 3.18.11+ #781 PREEMPT Tue Apr 21 18:02:18 BST 2015 armv6l GNU/Linux
The Raspberry Pi pinger-raspberry.slac
..stanford.edu an armv61 running Gnu Linux (see above).
Code Block 103cottrell@pinger:~$uname -a Linux pinger 2.6.32-504.8.1.el6.i686 #1 SMP Fri Dec 19 12:14:17 EST 2014 i686 i686 i386 GNU/Linux
Both were in the same building at SLAC, i.e. roughly at latitude 37.4190 N, longitude 122.2085 W.
The measurements were made between pinger.slac.stanford.edu and pinger-raspberry.slac.stanford.edu and from both pinger.slac.stanford.edu and pinger-raspberry.slac.stanford.edu to targets at varying distances and hence varying minimum RTTs from SLAC.
Analysis
Looking for significant differences in the measurements of the more important metrics (minimum, average, median and jitter of RTT and loss) that impact applications such as throughput, voice over IP, streaming video, haptics.
