Subject: Review of draft-ietf-xrblock-rtcp-xr-jb-12

I have reviewed this document as part of the security directorate's
ongoing effort to review all IETF documents being processed by the IESG.
These comments were written primarily for the benefit of the security
area directors. Document editors and WG chairs should treat these
comments just like any other last call comments.

This internet-draft specifies a RTP Control Protocol (RTCP) Extended Report
(XR) Block for data on jitter buffer configuration and performance.

The security considerations section does exist and states that the new block
data does not introduce any additional security concerns than those stated
in the base XR spec, RFC 3611.  I believe this to be an accurate assertion.

General comments:

I found the draft slightly hard to read, as the terminology and abbreviations
used are not expanded.  For example, the abstract has "RTP", but never expands
the abbreviation.

[Qin]; RTP is abbreviation of  "A Transport Protocol for Real-Time Applications" and defined
In the basic RTP protocol specification [RFC3550], it is the basic atom we are used 
in the context of this draft and can not be decomposed.For other term and abbreviation,
I will check and fix that, thanks.
