Delay-Tolerant Networking TCP Convergence-Layer Protocol Version 4
RFC 9174, “Delay-Tolerant Networking TCP Convergence-Layer Protocol Version 4”, is a Proposed Standard document published in January 2022 by B. Sipos, M. Demmer, J. Ott, S. Perreault. The canonical text is published by the RFC Editor.
Abstract
This document describes a TCP convergence layer (TCPCL) for Delay-Tolerant Networking (DTN). This version of the TCPCL protocol resolves implementation issues in the earlier TCPCL version 3 as defined in RFC 7242 and provides updates to the Bundle Protocol (BP) contents, encodings, and convergence-layer requirements in BP version 7 (BPv7). Specifically, TCPCLv4 uses BPv7 bundles encoded by the Concise Binary Object Representation (CBOR) as its service data unit being transported and provides a reliable transport of such bundles. This TCPCL version also includes security and extensibility mechanisms.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
