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.
