[lmap] Which performance metrics for LMAP?

[Benoit Claise <[e-mail]>]

Dear all,

Another clarifying question: I'm not too sure which performance metric 
types LMAP targets.
draft-linsner-lmap-use-cases-00 mentions:

    It is assumed that measurement
    tests run by OTT providers would only include the metrics associated
    with layer 3 and up


The different drafts use different terms: service, end user experience, 
quality of experience.
Does Quality of Experience imply performance metrics per application, 
per 5 tuple (IP addresses, ports, protocol), per DCSP?
Or do we want to stay at layer 3 performance metrics, typically IPPM 
type of metrics?
If the latter, then LMAP is about large scale deployment of IPPM, right?

While I fully understand the business needs for "and up" in "include the 
metrics associated with layer 3 and up", let's not boil the ocean.
Performance Metrics at Other Layer (PMOL 
<http://datatracker.ietf.org/wg/pmol/charter/>), a concluded WG, tried 
and it proved to be difficult.

Some more discussions, on the mailing list or during the BoF, on this 
topic would be appreciated.

Regards, Benoit
