Introduction
This is a study of the differences (if any) of the measurements from pinger.slac.stanford.edu (a single (raw hardware non-virtual) Linux host running the PingER Measurement Agent (MA) measuring the ping Round Trip Times (RTTs) to pingervm (AKA dhcp-nebula-124-66.slac.stanford.edu a Nebulr KVM Virtual Machine) and vice versa. Hencefiorth we refer to ping requests from pinger to pingervm as pinger to pingervm or pinger>pingervm and ping requests from pingervm to pinger as pinger to pingervm or pingervm>pinger. Both pinger and pingervm are located on the second floor of Building 50 (the computer center) at SLAC. The traceroutes between the two machines are seen here
