Re: [ippm] FW: New Version Notification for draft-li-ippm-otwamp-on-lag-02.txt

Hi Jun,

Thanks for your comments.
I think the description is indeed confusing.
IMO, there is only one micro session create command sent to the reflector.
So that the reflector can behave for all the micro session tests.
And no need to build an association between the session and the member link.
Is that reasonable?

Best,
Tianran

Hi Tianran,

I have review the new version, LAG performance measurement is a important feature,I think this work is very meaningful. I support it and hope it can evolve forward.

In addition, I have a question below:

   "To support the micro TWAMP session, a new command, Request-TW-Micro-

   Session (TBD2), is defined in this document.  The Request-TW-Micro-

   Session command is based on the TWAMP Request-Session command, and

   uses the message format as described in Section 3.5 of TWAMP [RFC5357]. "

My question is: member links have the same source IP 、destination IP 、source port number, and destination port number, if use the message format as described in Section 3.5 of TWAMP[RFC5357]. How to distinguish member link session of LAG?

Hi WG,

We think this is an useful work on adapting OWAMP/TWAMP in LAG performance measurement.
We updated this draft based on the comments from the meeting discussion and mailing list.
Thanks for all the suggestions.
More reviews and comments are welcome.

Cheers,
Tianran

Name:        draft-li-ippm-otwamp-on-lag

Title:        One-way/Two-way Active Measurement Protocol Extensions for Performance Measurement on LAG

Abstract:
   This document defines extensions to One-way Active Measurement
   Protocol (OWAMP), and Two-way Active Measurement Protocol (TWAMP) to
   implement performance measurement on every member link of a Link
   Aggregation Group (LAG).  Knowing the measured metrics of each member
   link of a LAG enables operators to enforce the performance based
   traffic steering policy across the member links.
