This repository contains the source code for the controller logic that was used in the LCDN paper. The repo mainly offers the business logic for now. LCDN also has an implementation that directly works with hardware. However, the code quality is not in a state that we feel comfortable to publish it yet.
The Repo follows the structure of LCDN. Below the most important parts are listed.
-- LCDN
|-- core
|-- Network
|-- Network Calculus
|-- Routing
|-- manager.py
The core folder represent our efforts to refactor LCDN's business logic and include the hardware interface.
Network contains all functions and classes for building and managing the topology.
Network Calculus contains the implementation of the DNC framework
Routing offers the Routing Manager and all auxiliary functions.
maanger.py contains the main LCDN implementation
The file example.py in the root of the directory contains a simple example on how to use LCDN's business logic.
Track the progess of the core unification for LCDN.
- Move current Business Logic to new Interface (core)
- HTTP API for LCDN
- Hardware Interface Refactoring
- LLDP Module
- Raspberry Pi Middleware
- Switch Controller
If you have any questions regarding the state of LCDN or its functionality, feel free to contact per mail [email protected]
The Controller was primarily introduced in the paper: "LCDN: Providing Network Determinism with Low-Cost Switches". If you use LCDN, please cite our paper
