Crate rat_congestion 

RAT Congestion Control Library

A high-performance, platform-optimized congestion control library implementing BBR and CUBIC algorithms with intelligent switching capabilities.

This library is designed as a pure computational engine that processes network data provided by the caller, without collecting any system data itself.

Features

• Pure Computation: No system data collection, all data provided by caller
• BBR Algorithm: Google’s Bottleneck Bandwidth and Round-trip propagation time algorithm
• CUBIC Algorithm: High-performance CUBIC congestion control with optimizations
• Intelligent Switching: Dynamic algorithm selection based on network conditions
• Platform Optimizations: Automatic platform detection and SIMD optimizations
• Zero-Copy Design: Minimal allocations and efficient batch processing
• Unified Entry Point: Single API for all platforms, auto-configured

Quick Start

use rat_congestion::{CongestionController, PacketEvent};
use std::time::Duration;

// Create a controller with automatic platform optimization
// Note: In real usage, you need to provide NetworkMetrics and MetricsWindow implementations
// let mut controller = CongestionController::new(metrics, metrics_window);

Advanced Usage

use rat_congestion::{CongestionController, ControllerConfig};

// Create with custom configuration
let config = ControllerConfig::builder()
    .initial_algorithm("bbr")
    .auto_switching(true)
    .build();

// Note: In real usage, you need to provide NetworkMetrics and MetricsWindow implementations
// let mut controller = CongestionController::with_config(config, metrics, metrics_window);
