This document describes a revised protocol for the TCP-based convergence layer for Delay-Tolerant Networking (DTN). The protocol revision is based on implementation issues in the original [RFC7242] and updates to the Bundle Protocol contents, encodings, and convergence layer requirements in [I-D.ietf-dtn-bpbis]. The majority of this specification is unchanged from TCPCL version 3.
