Abstract:

   Motivated by the need to support multiple in-network services and
   functions in an MPLS network (a.k.a.  MPLS Network Actions or MNA),
   this document describes a generic and extensible method to
   encapsulate MNA instructions as well as possible ancillary data in an
   MPLS packet.  All the post-stack MNAs are encapsulated in a structure
   called Post-stack Action Header (PAH).  A PAH is composed of a common
   header plus a chain of extension headers with each serving as a
   container for an MNA.  The encapsulation method allows chaining
   multiple post-stack extension headers and provides the means to
   enable fast access to them as well as the original upper layer
   headers.  We confine this document to the solution of PAH encoding
   and leave the specification of PAH indicator to the overall MNA
   solution.  We show how PAH can be used to support several new MNAs as
   a generic post-stack mechanism.
