[ NNSquad ] Re: "How to Patrol Your ISP"

[Rahul Tongia <tongia@cmu.edu>]

Sorry for joining (responding) late to the discussions.

I have been toying with the idea of such measurements for a while, and 
am in the process of proposing something like this to NSF, in fact.

I don't think that would conflict with the goals discussed here, and 
could overlap nicely.

From what I understand, CAIDA focuses on AS (BGP) level issues (KC or 
others, please correct me)?

We're talking about something vastly more distributed.

IMHO, creation of the tools is one thing, but designing a process and 
system is a lot more complicated:
1) What data will it collect - conversely, what data won't it collect?
2) Is this meant to be end-user voluntary? Why would they participate? 
What information would they be willing to share (or not)?
3) Privacy issues
4) What would we (anyone) be able to do with such data?
5) Who would have access to such data?
6) International and jurisdiction issues
7) Is this only for retail (consumer) connections?
8) Is the intent to only consider the last (ISP) hop, or also consider 
end-to-end issues, e.g., bottlenecks or gateway issues?  The latter are 
esp. key for international or remote users, who might actually do "fine" 
in the first few hops. There are many subtleties when we consider the 
flip of last mile as first mile (where content lies, which may be either 
at the edge or in some centralized server).
