1.  Introduction

   This document reminds the existence of the "Segment Routing (SR) MPLS
   dataplane with IPv6 control-plane".  This solution is mature from a
   standardization, productization and commercial deployment viewpoint.
   Other proposed source routing solutions with MPLS-like label lookup
   or mapping ids should list all their data-plane and control-plane
   differences with respect to this mature solution and should justify
   these differences with genuine benefits not available in the mature
   solution described in this document and others referenced here that
   are published by the SPRING and MPLS WGs.

2.  Context

   This is an existing solution.

   o  Mature IETF standardization

   o  Mature productization

   o  Commercially deployed

   The IETF standardization references are:

   o  Architecture:

      *  Segment Routing [RFC8402]

   o  Data-plane:

      *  Homogenous MPLS deployment:

      *  Hopping over IP-only parts of network:
         [I-D.ietf-mpls-sr-over-ip]

   o  Control-plane:
