Abstract:
   This document specifies a mechanism, referred to as "Intent Driven
   Service Mapping", that uses BGP to express intent based association
   of overlay routes, with underlay routes having specific Traffic
   Engineering (TE) characteristics, that satisfy a certain Service
   Level Agreement (SLA).  The document achieves this by defining new
   constructs, to group underlay routes with sufficiently similar TE
   characteristics into identifiable classes (called, Transport
   Classes), that overlay routes use as an ordered set to resolve
   reachability (Resolution Schemes) towards service endpoints.  These
   constructs can be used, e.g., to realize the "IETF Network Slice"
   defined in TEAS Network Slices framework.

   This document specifies protocol procedures for BGP that enable
   dissemination of service mapping information in a network that may
   span multiple cooperating administrative domains.  These domains may
   be administered either by the same provider or by closely
   coordinating providers.  A new BGP address family that leverages RFC
   4364 procedures and follows RFC 8277 NLRI encoding, is defined to
   advertise underlay routes with its identified class.  This new
   address family is called "BGP Classful Transport", a.k.a., BGP CT.
