Module quality_predictor 

Connection Quality Predictor

This module provides connection quality prediction based on historical performance data. It tracks metrics like latency, bandwidth, reliability, and uptime to predict future connection quality and enable proactive switching to better connections.

Features

• Historical metric tracking per peer
• Quality scoring based on multiple factors (latency, bandwidth, reliability, uptime)
• Exponential moving average for smooth predictions
• Configurable weights for different metrics
• Proactive connection recommendations
• Automatic degradation detection

Example

use ipfrs_network::quality_predictor::{QualityPredictor, QualityPredictorConfig};
use libp2p::PeerId;

let config = QualityPredictorConfig::default();
let predictor = QualityPredictor::new(config)?;

let peer = PeerId::random();

// Record metrics
predictor.record_latency(peer, 50);
predictor.record_bandwidth(peer, 1_000_000);
predictor.record_success(peer);

// Get quality prediction
if let Some(quality) = predictor.predict_quality(&peer) {
    println!("Predicted quality: {}", quality.overall_score);
}

// Check if connection should be switched
if predictor.should_switch_connection(&peer) {
    println!("Consider switching to a better peer");
}
