Hi Brendan,

Thanks for the pointer! Unfortunately, not all devices that can perform traceroutes are suitable for my issue; I can only use those that also allow me to inspect their routing table so I can compare the chosen control plane path with the actual data plane path. In addition, the richer a device's routing table the better---there is not much to measure with only a default route :)

Best regards,

Lars

Hi Lars,

You should check out https://ring.nlnog.net/ by contributing resources yourself you also get access to a wide array of machines from all across the world you can use to turn traceroutes and pings.

Some wrappers have already been made to run commands against multiple machines at the same time (https://ring.nlnog.net/toolbox/), you'll have SSH access to run any commands you want and there is an API to find the probes if you want to automate it all.

I encourage anyone and everyone to join. The more networks the better!

    Hi everyone,

    In the next couple of months, I want to compare data plane and
    control
    plane measurements on a larger scale. In particular, I'm looking for
    (publicly accessible) devices that receive BGP feeds and can
    perform a
    bunch of automated (paris) traceroutes. I currently do not have an
    exact
    probing rate or target set in mind; however, I'm sure that manually
    entering IP addresses as targets for usual Looking glasses won't
    cut it.
    Does anyone know less-restricted (maybe even automatable?) Looking
    Glasses (or similar devices) or is willing to provide access to one?

    BTW: I though about picking Atlas probes from ASes that feed BGP
    Collector Projects (e.g. RIPE RIS or RouteViews). Unfortunately, the
    respective probes are often really far apart from the feeding
    routers;
    thus, their individual perspectives are likely misaligned :(

    Best regards,

    Lars
