Abstract:
   The ability for a node to specify a forwarding path, other than the
   normal shortest path, that a particular packet will traverse,
   benefits a number of network functions.  Source-based routing
   mechanisms have previously been specified for network protocols, but
   have not seen widespread adoption.  In this context, the term
   'source' means 'the point at which the explicit route is imposed'.

   This document outlines various use cases, with their requirements,
   that need to be taken into account by the Source Packet Routing in
   Networking (SPRING) architecture for unicast traffic.  Multicast use-
   cases and requirements are out of scope of this document.
