Module tunneling

IPv6/IPv4 tunneling protocols IPv6/IPv4 Tunneling Implementation

This module provides comprehensive tunneling solutions for enabling IPv6 connectivity over IPv4 networks. It implements multiple tunneling protocols to ensure universal connectivity for the P2P Foundation networking stack.

Supported Protocols

• 6to4: Automatic tunneling of IPv6 traffic over IPv4 networks
• Teredo: NAT traversal for IPv6 connectivity through NAT devices
• 6in4: Configured tunneling for IPv6 over IPv4 with explicit endpoints
• DS-Lite: ISP-provided dual-stack lite tunneling
• ISATAP: Enterprise network tunneling for corporate environments
• MAP-E: ISP IPv4 sharing via encapsulation with mapping rules
• MAP-T: ISP IPv4/IPv6 translation with mapping rules

Architecture

The tunneling system uses a trait-based architecture that allows for:

• Protocol-agnostic tunnel management
• Automatic protocol selection based on network conditions
• Seamless integration with the transport layer
• Performance monitoring and failover capabilities
