Rust implementation of a daemon for DTN7 Bundle Protocol draft https://tools.ietf.org/html/draft-ietf-dtn-bpbis-26
Plus:
- Minimal TCP Convergence Layer Protocol https://tools.ietf.org/html/draft-ietf-dtn-mtcpcl-01
- A simple HTTP Convergence Layer
- Convenient command line tools to interact with the daemon
- A simple web interface for status information about
dtnd - A web-socket interface for application agents
The actual BP7 implementation can be found here: https://github.com/dtn7/bp7-rs
Additional dtn related stuff and some client code can be found here: https://github.com/dtn7/bp7-plus-rs
A similar golang implementation can be found here: https://github.com/dtn7/dtn7-go
Currently a very basic service discovery, MTCP & HTTP CLs, flooding/epidemic/sink-routing and rest/ws command interfaces are implemented. Both addressing schemes, dtn as well as ipn are supported. Furthermore, some CLI tools are provided to easily integrate dtn7 into shell scripts.
Beware, the API is not always idiomatic rust and lacks documentation and tests at the moment.
I consider this code to be work-in-progress and not finished yet. Also the rest and web-socket interface is totally undocumented and unfinished at the moment :)
Installation from source using cargo:
cargo install dtn7
$ dtnd -h
dtn7-rs 0.11.0
Lars Baumgaertner <baumgaertner@cs.tu-darmstadt.de>
A simple Bundle Protocol 7 Daemon for Delay Tolerant Networking
USAGE:
dtnd [FLAGS] [OPTIONS]
FLAGS:
-d, --debug Set log level to debug
-h, --help Prints help information
-4, --ipv4 Use IPv4
-6, --ipv6 Use IPv6
-U, --unsafe-httpd Allow httpd RPC calls from anyhwere
-V, --version Prints version information
OPTIONS:
-C, --cla <CLA[:local_port]>... Add convergency layer agent: dummy, mtcp, http
-c, --config <FILE> Sets a custom config file
-D, --db <STORE> Set bundle store: mem, sled
-e, --endpoint <ENDPOINT>... Registers an application agent for a node local endpoint (e.g. 'incoming' listens
on 'dtn://node1/incoming')
-i, --interval <humantime> Sets service discovery interval (0 = deactive, 2s = 2 seconds, 3m = 3 minutes,
etc.)
-j, --janitor <humantime> Sets janitor interval (0 = deactive, 2s = 2 seconds, 3m = 3 minutes, etc.)
-n, --nodeid <NODEID> Sets local node name (e.g. 'dtn://node1')
-p, --peer-timeout <humantime> Sets timeout to remove peer (default = 20s)
-r, --routing <ROUTING> Set routing algorithm: epidemic, flooding, sink
-s, --static-peer <PEER>... Adds a static peer (e.g. mtcp://192.168.2.1:2342/node2)
-w, --web-port <PORT> Sets web interface port (default = 3000)
-W, --workdir <PATH> Sets the working directory (e.g. '/tmp/node1', default '.')
Example usage for node1 with epidemic routing, mtcp convergence layer and the default endpoint 'incoming':
$ dtnd -n node1 -r epidemic -C mtcp -e incoming
The same but with ipn addressing scheme and a default endpoint at 23.42:
$ dtnd -n 23 -r epidemic -C mtcp -e 42
Configuration can also happen via a config file.
For an example take a look at examples/dtn7.toml.example.

-x, --hex hex output
-6, --ipv6 Use IPv6
-V, --version Prints version information
-v, --verbose verbose output
OPTIONS:
-b, --bundle-id <BID> Download any bundle by ID
-e, --endpoint <ENDPOINT> Specify local endpoint, e.g. '/incoming', or a group endpoint 'dtn://helpers/incoming'
-o, --output <FILE> Write bundle payload to file instead of stdout
-p, --port <PORT> Local web port (default = 3000)
Sending bundles:
$ dtnsend -h
dtnsend 0.11.0
Lars Baumgaertner <baumgaertner@cs.tu-darmstadt.de>
A simple Bundle Protocol 7 Send Utility for Delay Tolerant Networking
USAGE:
dtnsend [FLAGS] [OPTIONS] --receiver <RECEIVER> [infile]
FLAGS:
-D, --dry-run Don't actually send packet, just dump the encoded one.
-h, --help Prints help information
-6, --ipv6 Use IPv6
-V, --version Prints version information

Automatic triggering of external binaries for incoming bundles:
$ dtntrigger -h
dtntrigger 0.11.0
Lars Baumgaertner <baumgaertner@cs.tu-darmstadt.de>
A simple Bundle Protocol 7 Incoming Trigger Utility for Delay Tolerant Networking
USAGE:
dtntrigger [FLAGS] [OPTIONS] --command <CMD>
FLAGS:
-h, --help Prints help information
-6, --ipv6 Use IPv6
-V, --version Prints version information
-v, --verbose verbose output
OPTIONS:
-c, --command <CMD> Command to execute for incoming bundles, param1 = source, param2 = payload file
-e, --endpoint <ENDPOINT> Specify local endpoint, e.g. '/incoming', or a group endpoint 'dtn://helpers/incoming'
-p, --port <PORT> Local web port (default = 3000)
A simple DTN echo service can be found under examples/dtnecho.rs.
This service automatically registers its endpoint and listens for any incoming bundles on the local /echo endpoint or for ipn addresses on service number 7.
Each bundle is sent back to its source with the same payload and lifetime, no delivery report is requested.
