Re: [ippm] AD review: draft-ietf-ippm-storetraceroutes-03



Lars,

I haven't seen any reply to these comments yet.

Sorry, I seem to have missed this mail, otherwise I'd asked about it before closing the WGLC.


Section 5.2., paragraph 0:
> 5.2.  Information Elements

  Does it make sense to have default values for the information elements
  at all? I mean, the data captured by the information model is the
  result of a particular traceroute measurement, which will have been
  taken with a fully specified set of parameters. So the defaults will
  never be actually used, no?

I'd personally prefer sensible defaults for values over "undefined" or "NaN" when creating a new instance of a measurement. That way, I don't have to remember that my code should change the values. YMMV, but I don't think it hurts to have them.


Section 3., paragraph 3:
>    in the path).  Upon receiving a probe, the first hop host decreases
>    the TTL value by one.

Nit: Routers can decrease the TTL by more than one.

Is this a big issue or can we fix this in IESG-LC?

Henk
