Requirements for Solutions that Support MPLS Network Actions (MNAs)

This document specifies requirements for the development of MPLS Network Actions (MNAs) that affect the forwarding or other processing of MPLS packets. These requirements are informed by a number of proposals for additions to the MPLS information in the labeled packet to allow such actions to be performed, either by a transit or terminating Label Switching Router (i.e., the Label Edge Router - LER).
