Overview
Project Title	First-Hop / Last-Hop Applications for DTN
Approval	Draft
Document Number
Charter	6.09 Delay Tolerant Networking Working Group
Document Type	Blue
Description of Document	Applications supporting conversion between BP network communications and link-layer communication with a spacecraft. For example, if a spacecraft is nominally DTN-enabled but is not responding to network commands, the 'last-hop' application would ingest bundles sent to it by some controller and cause link-layer frames to be emitted to the target S/C (presumably to perform link-layer commanding). A similar application could consume RF and package it into bundles for transmission via the network. This capability is described in IOAG Service Catalog 2
