Re: [hops] Fwd: measurement platforms and their capabilities (previously was HOPS bar bof notes)

[Joachim Fabini <[e-mail]>]

Hi Mirja, all

we can contribute some methodological findings and advances in one-way
delay measurements.

Background: Today's networks have evolved to complex, stateful systems
(at layers below IP). It's time to question the stateless copper wire
model, the main abstraction on which our algorithms, applications, and
measurements rely. We can improve measurement methodologies to better
capture the behavior of networks and to find out where the limits of
measurements are.

Concerning the hops charter: from an end-to-end perspective it's very
hard to differentiate if systematic impairments have been caused by a)
network operation and coding at lower layers and b) middlebox actions
(unless these middleboxes modify network, transport- or application
header values). In other words, it is difficult to draw a line between
network scheduling, policing and middlebox behavior that directly
affects the extensibility of the Internet. Aggregation and interaction
of subsequent links in a path complicate matters even more.
The main point is that accurate delay measurements can detect (some?)
network elements on the path that maintain state. And these are
potential/ideal candidates for substantially touching other layers, too.

If there is interest in hops I can present some slides at the next
meeting @ IETF94 (online or offline, depending on travel/time budget).
My feeling is that the findings can support some of the ongoing projects
(RIPE, Monroe).
