The ability for a node to specify a unicast forwarding path, other than the normal shortest path, that a particular packet will traverse, benefits a number of network functions, for example:

               Source Packet Routing in Networking (SPRING)                    Problem Statement and Requirements


   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";    therefore, it is not limited to the originator of the packet (i.e.,    the node imposing the explicit route may be the ingress node of an    operator's network).

   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 for this document.
