The IESG has received a request from the Delay/Disruption Tolerant Networking
WG (dtn) to consider the following document: - 'Delay-Tolerant Networking TCP
Convergence Layer Protocol Version 4'
  <draft-ietf-dtn-tcpclv4-15.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 2019-11-06. 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.


   This document describes a revised protocol for the TCP-based
   convergence layer (TCPCL) for Delay-Tolerant Networking (DTN).  The
   protocol revision is based on implementation issues in the original
   TCPCL Version 3 of RFC7242 and updates to the Bundle Protocol
   contents, encodings, and convergence layer requirements in Bundle
   Protocol Version 7.  Specifically, the TCPCLv4 uses CBOR-encoded BPv7
   bundles as its service data unit being transported and provides a
   reliable transport of such bundles.  Several new IANA registries are
   defined for TCPCLv4 which define some behaviors inherited from
   TCPCLv3 but with updated encodings and/or semantics.
