This document extends STUN [RFC5389] to make it possible to correlate STUN responses to specific requests when retransmits occur. This assists the client in determining path characteristics like round- trip time (RTT) and fractional packet loss.

Measurement of Round-Trip Time and Fractional Loss Using Session Traversal Utilities for NAT (STUN)
A host with multiple interfaces needs to choose the best interface for communication. Oftentimes, this decision is based on a static configuration and does not consider the path characteristics, which may affect the user experience.
This document describes a mechanism for an endpoint to measure the path characteristics fractional loss and RTT using Session Traversal Utilities for NAT (STUN) messages.
