Reviewer: Wesley Eddy
Review result: Ready with Issues

This document has been reviewed as part of the transport area review team's
ongoing effort to review key IETF documents. These comments were written
primarily for the transport area directors, but are copied to the document's
authors and WG to allow them to address any issues raised and also to the IETF
discussion list for information.

When done at the time of IETF Last Call, the authors should consider this
review as part of the last-call comments they receive. Please always CC
tsv-art@ietf.org if you reply to or forward this review.

I reviewed this in conjunction with the set of related WG documents on
NETCONF/RESTCONF subscriptions and event notifications.   I have comments that
will be sent on other documents in the set, some of which may influence this
once, since they are closely related.

Figure 3 shows a DSCP value of 10, but it isn't clear what the number base is
supposed to be, and this should be specified for this protocol, since many
examples can be found in other material of DSCP values indicated in binary,
decimal, or hexadecimal.

In section 4, the first bullet discusses taking a "priority" and copying it
into a "weighting" field.  Since priority and weight can be different, though
are closely related, this seems a bit confusing.  I think the intention here
for HTTP2 effects that are trying to be achieved should be discussed more so
that it is clear to implementers and users what more specific effects this
should have.
