"Dyloc computes the round trip delay captured packets experience between the packet capture point (CP) to a host (the "passive ping") when both directions of a flow are available. For single direction flows, dlyloc computes delay variation observed for different segments." https://github.com/pollere/DlyLoc "DlyLoc is meant for network nerds who can get information from the code. There are comments to note where additional data collection could occur but DlyLoc has been kept fairly basic. No support is provided; this code is offered as an example or a basis for the interested. DlyLoc is a simplified and slightly modified version of TSDE which was used in some previous talks. This version has not been extensively tested. Some additional information and pictures of processed output (using TSDE) are at: http://pollere.net/netobserve.html and http://pollere.net/Pdfdocs/ListeningGoog.pdf " --=20 I tried to build a better future, a few times: https://wayforward.archive.org/?site=3Dhttps%3A%2F%2Fwww.icei.org Dave T=C3=A4ht CEO, TekLibre, LLC
