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.
