Extensible Provisioning Protocol (EPP) Transport over QUIC

This document specifies how the Extensible Provisioning Protocol (EPP) is mapped onto the QUIC transport . QUIC is a network protocol that is based on UDP and incorporates native encryption support using TLS . Though based on UDP, QUIC provides connection semantics like other stateful protocols. This document discusses how EPP implementations can work with this and other features of QUIC while preserving the core EPP semantics. EPP sessions use a single QUIC stream for all command and response exchanges throughout the session lifecycle. Unlike stateless transaction protocols that permit per-command independent streams, EPP is a stateful protocol with inherent sequential command dependencies defined in .
