Distributed Elevator System

Introduction

This project implements a distributed system utilizing a peer-to-peer network architecture, designed for the "Real-time programming" course at the Norwegian University of Science and Technology (NTNU). It facilitates the operation of multiple elevator instances within an elevator lab environment, ensuring a seamless and efficient elevator control system.

Getting Started

Prerequisites

  • Ensure that Rust is installed on your system. If Rust is not installed, follow the installation instructions on the official Rust website.
  • Amd64 architecture to run linux executables

Running the Project

To launch an elevator instance, open a terminal and execute the following command:

cargo run

For increased verbosity and detailed logging, use:

RUST_LOG=trace,network_rust=off cargo run

The same command can be initiated on multiple computers to initiate multiple elevators working in tandem within the peer-to-peer network.

Configuration

For the distributed system to function correctly, it is essential that all elevator instances share the same network configuration. Place the following settings within the config.toml file:

[network]
msg_port = 19735
peer_port = 19738

The elevator server can be initiated by running the following command at one of the computers in the real-time lab:

elevatorserver

The hardware module must know which port to use for hardware API calls, and this defaults to 15657. Place this in the config.toml file:

[hardware]
n_floors = 4
driver_address = "localhost"
driver_port = 15657

Use n_floors = 4 at the real-time lab.
