    abstract =  {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.},
