Module multipath_quic 

QUIC Multipath Support

This module implements multipath QUIC connections, allowing a single connection to use multiple network paths simultaneously for improved reliability, throughput, and seamless network transitions.

Features

• Multiple Paths: Manage multiple network paths for a single connection
• Path Quality Monitoring: Track latency, bandwidth, and packet loss per path
• Traffic Distribution: Distribute traffic across paths based on quality and strategy
• Path Migration: Seamlessly migrate between paths when quality changes
• Load Balancing: Balance load across available paths for optimal throughput
• Redundancy: Send critical data on multiple paths for reliability

Path Selection Strategies

• Round Robin: Distribute traffic evenly across all paths
• Quality Based: Prefer paths with better quality metrics
• Lowest Latency: Always use the path with lowest latency
• Highest Bandwidth: Always use the path with highest bandwidth
• Redundant: Send data on all paths for maximum reliability

Example

use ipfrs_network::multipath_quic::{MultipathQuicManager, MultipathConfig, PathSelectionStrategy};

// Create multipath manager with quality-based strategy
let config = MultipathConfig {
    max_paths: 4,
    strategy: PathSelectionStrategy::QualityBased,
    enable_redundancy: false,
    ..Default::default()
};

let mut manager = MultipathQuicManager::new(config);

// Paths will be automatically detected and managed
// Traffic will be distributed based on the configured strategy
