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.
