Features

• High performance and memory safety through Rust
• Support for OpenFlow 1.0 and 1.3
• Asynchronous operation with Tokio
• Built-in example controllers
• Command-line interface for quick testing
• Mininet integration for network emulation

Quick Start

As a Command-Line Tool

1. Install Rust and Cargo:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

2. Install Tenjin:

cargo install tenjin_sdn

3. Run the example controller:

tenjin run

As a Library

1. Add Tenjin to your project:

cargo add tenjin_sdn

2. Add Tokio for async support:

cargo add tokio

3. Use in your code:

use tenjin_sdn::{example, openflow::ofp13::ControllerFrame13};

#[tokio::main]
async fn main() {
    let controller = example::Controller13::new();
    controller.listener("127.0.0.1:6633");
}

4. if you would like to create your own Controller, you need to install etherparse.

cargo add etherparse
