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. Abstract 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. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-dtn-tcpclv4/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-dtn-tcpclv4/ballot/ No IPR declarations have been submitted directly on this I-D.
