[MBONED] R: Draft mtg minutes

Lenny, just a couple of clarifications regarding my presentation, marked with [ATB].

draft-cociglio-mboned-multicast-pm-00
  A method for multicast performance monitoring
  Stig, why does it have to be self contained?
  Marshall, why not for instance use RTP if you happen
    to have an RTP stream, why not use the information.
  Someone asked some question on jabber

  Marshall, where do you put the timestamp? Are you
  doing just one bit?

[ATB] The bit (f.i. in DSCP field) is just used to mark the traffic to be monitored and determine when to take the timestamp. Timestamp itself
is not stored in the packet header but sent to an external system which performs the actual measurement.

  Marshall and user online comments on timestamps and
    synced clocks for delay
  Author: they have done it for packet loss. they are
    still looking into time stamps and checking jitter
    etc.
  Ilya Valashkin (sp?) online says trials needed for
    timestamps, it can be complicated.
  Toerless, says he wonders what is the best wg. He
    mentions IPPM. It has already been there though?
  Stig, we can in this wg say what measurements we need
    but maybe not how
  Iliya mentions MPOL?

[ATB] PMOL work is about performance metrics for other layers, IP performance metrics are discussed in IPPM WG.

  Marshall, this group could do requirements
  Stig, question about reordering and marking
  Author: not an issue
  Author: figured that IPPM best place...
  Vero: there is interest in IPPM, but chair decided
  not sufficient to take it on.

Thanks,
Alberto
