Hi all,

I have been selected as the Operational Directorate reviewer for this draft.

Summary:
I think this draft is ready for publication after the nits fixed.

Comments: 
This draft uses IPsec tunnel mode to improve confidentiality by hiding inner packet identifiable information, packet size and packet timing. The document is well-written and readable.

Major Issues:
None
 
Minor Issues:
None

Query:
Section 4.  Configuration of AGGFRAG Tunnels for IP-TFS 
This section defines the configurations of three parameters: Bandwidth, packet size, and congestion control. It also says "No standardized configuration method is required."  As I see WG is working on YANG and MIB drafts related to this draft. I am wondering if these drafts can be referenced in this section as examples of the configuration and operation method?

Nits：
- Expand on first use: ESP,CC

2.2.3.1.  Optional Extra Padding
OLD：
While use of padding to avoid fragmentation does not impact
   interoperability, used inappropriately it can reduce the effective
   throughput of a tunnel.

Appendix C C.1.  Comparing Overhead
OLD
For comparing overhead the overhead of ESP for both normal and
   AGGFRAG tunnel packets must be calculated,
