Hi, Pavan,

Thank you for the update.

Could you explain a bit the motivation of this update? Since now it is SHOULD not MUST; so with a good reason, the ingress/egress can choose to ignore such label modify received from the other end, by not tuning the new wavelength, will it be any issue? Any additional texts needed to handle it?

  I will send more detailed review comments probably after this IETF.

Regards,
Xian

WG, Hi!
Latest Update:
A new version was published recently. The following are the diffs -

     *   Section 6.2 - Change MUST->SHOULD

        *   “In such a scenario, if the ingress client receives a changed label via the LABEL object in a RESV modify, it SHOULD retune the laser at the ingress to the new wavelength. Similarly if the egress client receives a changed label via UPSTREAM_LABEL/LABEL_SET in a PATH modify, it SHOULD retune the laser at the egress to the new wavelength.”

     *   Added Zafar Ali to the list of contributors
Open Issues:
None.
Next Steps:
Request further review from the WG (authors believe that the draft is ready to progress to the next stage)

Regards,
-Pavan
