       Unified Source Routing Instruction using MPLS Label Stack
          draft-xu-mpls-unified-source-routing-instruction-00

Abstract

   MPLS-SPRING is an MPLS-based source routing paradigm in which a
   sender of a packet is allowed to partially or completely specify the
   route the packet takes through the network by imposing stacked MPLS
   labels to the packet.  This MPLS -based source routing paradigm could
   actually be leveraged to realize a unified source routing instruction
   for both IPv4 and IPv6 underlays.

1.  Introduction

   MPLS-SPRING [I-D.ietf-spring-segment-routing-mpls] is a MPLS-based
   source routing paradigm in which a sender of a packet is allowed to
   partially or completely specify the route the packet takes through
   the network by imposing stacked MPLS labels to the packet.  This
   MPLS-based source routing paradigm could actually be leveraged to
   realize a unified source routing instruction for both IPv4 and IPv6
   underlays.  In other words, the source routing instruction
   information contained in IPv4 and IPv6 source routed packets could be
   uniformly encoded as an MPLS label stack.  As a result, there is no
   need any more to develop and implement transport-dependent source
   routing mechanisms for IPv4 and IPv6 respectively.

   The traditional IPv4 and IPv6 source routing mechanisms by use of
