Rust implementation of a daemon for DTN7 Bundle Protocol draft https://tools.ietf.org/html/draft-ietf-dtn-bpbis-23
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 similar golang implementation can be found here: https://github.com/dtn7/dtn7-go
The actual BP7 implementation can be found here: https://github.com/dtn7/bp7-rs
Currently a very basic service discovery, MTCP & HTTP CLs, flooding/epidemic/sink-routing and a rest command interface are implemented. Both addressing schemes, *dtn* as well as *ipn* are supported.
**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 interface is totally undocumented and unfinished at the moment:)
## Installation
```
cargo install dtn7
```
## Usage
### Daemon
```
$ dtnd -h
dtn7-rs 0.6.0
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
-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
-e, --endpoint <ENDPOINT>... Registers an application agent for a node local endpoint (e.g. 'incoming' listens
on 'dtn://node1/incoming')
-i, --interval <MS> Sets service discovery interval (0 = deactive)
-j, --janitor <MS> Sets janitor interval (0 = deactive)
-n, --nodeid <NODEID> Sets local node name (e.g. 'dtn://node1')
-p, --peer-timeout <SECONDS> Sets timeout to remove peer
-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)
```
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`.
### Helpers
Querying information from `dtnd`:
```
$ dtnquery -h
dtnquery 0.6.0
Lars Baumgaertner <baumgaertner@cs.tu-darmstadt.de>
A simple Bundle Protocol 7 Query Utility for Delay Tolerant Networking
USAGE:
dtnquery [OPTIONS] [SUBCOMMAND]
FLAGS:
-h, --help Prints help information
-V, --version Prints version information
OPTIONS:
-p, --port <PORT> Local web port (default = 3000)
SUBCOMMANDS:
bundles list bundles in node
eids list registered endpoint IDs
help Prints this message or the help of the given subcommand(s)
info General dtnd info
nodeid Local node id
peers list known peers
store list bundles status in store
```
Receiving bundles:
```
$ dtnrecv -h
dtnrecv 0.4.0
Lars Baumgaertner <baumgaertner@cs.tu-darmstadt.de>
A simple Bundle Protocol 7 Receive Utility for Delay Tolerant Networking
USAGE:
dtnrecv [FLAGS] [OPTIONS] --endpoint <ENDPOINT>
FLAGS:
-h, --help Prints help information
-V, --version Prints version information
-v, --verbose verbose output
OPTIONS:
-e, --endpoint <ENDPOINT> Specify local endpoint, e.g. '/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 0.6.0
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
-V, --version Prints version information
-v, --verbose verbose output
OPTIONS:
-p, --port <PORT> Local web port (default = 3000)
-r, --receiver <RECEIVER> Receiver EID (e.g. 'dtn://node2/incoming')
-s, --sender <SENDER> Sets sender name (e.g. 'dtn://node1')
ARGS:
<infile> File to send, if omitted data is read from stdin till EOF
