       Unified Source Routing Instruction using MPLS Label Stack
          draft-xu-mpls-unified-source-routing-instruction-01

Abstract

   MPLS-SPRING is an MPLS data plane-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.  MPLS-SPRING could be leveraged to
   realize a unified source routing mechanism across MPLS, IPv4 and IPv6
   data planes by using a unified source routing instruction set while
   preserving backward compatibility with MPLS-SPRING.
