SUIP - Simple Unified Internet Protocol

Experimental internet protocol with its own markup format, server, and browser.

Overview

SUIP (Simple Unified Internet Protocol) is a minimalist data transfer protocol that combines the best approaches of modern protocols without the legacy baggage of HTTP.

Main Components:

• SUIP Server - TCP server implementing SUIP protocol in C
• SUIP Browser - GUI browser (client that understands SUIP) in .NET/Avalonia

Quick Start

1. Run the server

cd suip-server
cmake -S . -B build
cmake --build build
./build/suip-server

The server will start on port 2802 and serve files from ./www

2. Run the browser

dotnet run --project ./suip-browser/SuipBrowser/SuipBrowser.csproj

3. Open the demo site

In the browser's address bar, enter:

suip://localhost/index.xml
