The IESG has received a request from the IP Security Maintenance and
Extensions WG (ipsecme) to consider the following document: - 'IP-TFS:
Aggregation and Fragmentation Mode for ESP and its Use for IP
   Traffic Flow Security'
  <draft-ietf-ipsecme-iptfs-12.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-call@ietf.org mailing lists by 2022-05-18. Exceptionally, comments may
be sent to iesg@ietf.org instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.

Abstract


   This document describes a mechanism for aggregation and fragmentation
   of IP packets when they are being encapsulated in ESP payload.  This
   new payload type can be used for various purposes such as decreasing
   encapsulation overhead for small IP packets; however, the focus in
   this document is to enhance IPsec traffic flow security (IP-TFS) by
   adding Traffic Flow Confidentiality (TFC) to encrypted IP
   encapsulated traffic.  TFC is provided by obscuring the size and
   frequency of IP traffic using a fixed-sized, constant-send-rate IPsec
   tunnel.  The solution allows for congestion control as well as non-
   constant send-rate usage.
