Internet-Draft Minimal TCP Convergence-Layer Protocol April 2019
Abstract
This document describes a Minimal TCP (MTCP) "convergence-layer"
protocol for the Delay-Tolerant Networking (DTN) Bundle Protocol
(BP). MTCP uses Transmission Control Protocol (TCP) to transmit BP
"bundles" from one BP node to another node to which it is
topologically adjacent in the BP network. The services provided by
the MTCP convergence-layer protocol adapter utilize a standard TCP
connection for the purposes of bundle transmission.

1. Introduction
This document describes the Minimal TCP (MTCP) protocol, a Delay-
Tolerant Networking (DTN) Bundle Protocol (BP) [RFC5050]
"convergence layer" protocol that uses a standard TCP connection to
transmit bundles from one BP node to another node to which it is
topologically adjacent in the BP network.
Conformance to the MTCP convergence-layer protocol specification is
OPTIONAL for BP nodes.
Each BP node that conforms to the MTCP specification includes an
MTCP convergence-layer adapter (MCLA). Every MCLA engages in
communication via the Transmission Control Protocol [RFC0793].
Like any convergence-layer adapter, the MTCP CLA provides:

. A transmission service that sends an outbound bundle (from the
bundle protocol agent) to a peer CLA via the MTCP convergence
layer protocol.
. A reception service that delivers to the bundle protocol agent
an inbound bundle that was sent by a peer CLA via the MTCP
convergence layer protocol.
