Dear Authors,
I have couple comments to changes made in version 11 of the document:
* Introduction. A statement that e2e may "provide slow fault recovery" been added. Of course, if an operator to use slower fault detection and opt for service restoration rather than protection, then fault recovery will be slow. But if we to compare apples to apples, then I find this assumption unsubstantiated and hence don't see enough motivation for the proposed solution.
* Section 1.1 "Exactly how the failure is detected is out of scope for this document." I agree with this as long as you can demonstrate that egress failure can be detected and clearly identified specifically as egress failure in reasonable time.
Regards,
Greg
