1.  Introduction

   This draft provides a contol plane support for SRoU(Segment Routing
   over UDP).

   Discussion of this work is encouraged to happen on GitHub repository
   which contains the draft: https://github.com/zartbot/draft-quic-sr
   (https://github.com/zartbot/draft-quic-sr)

1.1.  Specification of Requirements

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in BCP
   14 [RFC2119] [RFC8174] when, and only when, they appear in all
   capitals, as shown here.

1.2.  Motivation

   SRoU support udp transport session over internet, but it lack of
   reachability detection and routing control, existing routing protocol
   like BGP-EVPN did not provide Dynamic NAT traversal capability.
