This document is almost ready for publication as an Informational RFC, with some nits.

Comments:

The document is well written, clear, and helpful to understand the IOAM framework. Sections 1-6 explain the different concepts and aspects of IOAM, section 7 provides some important considerations to be taken into account when deploying IOAM (perhaps the main section), section 8 provides some IOAM management recommendations, and finally section 10 provides an analysis of possible security threats and mitigations.

Nits:

- The draft's intended status is Informational. However, the Abstract mentions that the document provides a framework and discusses best current practices. Since the intended status is not BCP, I would suggest changing the sentence to something like "provides a framework and describes important IOAM deployment considerations,"

- Section 7 is introduced as "discussing aspects of IOAM." Although the section's scope is indeed very wide, I would suggest changing the text to something more descriptive and representative of the importance of this section, like "describes several concepts of IOAM, and provides considerations that need to be taken to account when implementing IOAM in a network domain."
