[RSSAC Caucus] [Non-DoD Source] Re: FOR REVIEW: Requirements for Measurements of the Local Perspective on the Root Server System

[Renard, Kenneth D CTR USARMY DEVCOM ARL (USA)]

Hi, Paul.  Thanks for the feedback.

The reasoning behind these latency measurements is to have some context for interpreting latency to root server instances.  For example, a slow "last mile" link would likely have effects on both root server and open resolver latencies.  The work party decided on using popular open resolvers as a reference latency target since they are a well-deployed service and have similar processing times (non-recursive DB lookup).  The exact math for such an analysis is not described in this document, but the reasoning is laid out at the end of section 2.1, under item #4 in the list of "measurements of interest".

If you think that additional text is required, I would be glad to propose something and work with you to address this.

Thanks!

-Ken

    Greetings again. I was not active in the work party, but I have done some review passes on the document late in the process. I still have a deep concern about the part in the middle where timings of some sort from open public resolvers are made. I put a comment in this near-final document, but have not seen any significant discussion. If RSSAC wants to do these probes, it would be really good if their use was explained in the document.
