IPPM,

I have read the documents and have several questions to the authors for clarification.

  1.  The document says that the measurement results can be used for traffic steering. AFAIK, LAG uses hashing for load balancing. Are you suggesting the new methods/algorithms for traffic distribution? Is there any existing or planed work for this?
  2.  This seems a proposal to use L3 protocols for L2 measurements. Is the L2 feature visible and manageable to the L3 entity?
  3.  Can you list the performance metrics that are measured and of interest to the LAG case for readers to better understand the motivation?
Thanks!

Best,
Haoyu

Subject: [ippm] Request for reviews of OWAMP/TWAMP/STAMP on LAG

Hi IPPM,
During the IPPM session at IETF 116 the authors of  draft-ietf-ippm-otwamp-on-lag and draft-ietf-ippm-stamp-on-lag expressed that they believe the documents are ready for WGLC.
However, since these documents were adopted quite recently we’d like to ask the WG to take some time to read them and provide feedback.

In response to this mail, please indicate whether you’ve read the document along with any feedback you might have.

Note that this is not an official working group last call.

The documents can be found here:
