   Title:   BGP Classful Transport Planes

Abstract:

   This document specifies a mechanism referred to as "Intent Driven
   Service Mapping".  The mechanism uses BGP to express intent based
   association of overlay routes with underlay routes having specific
   Traffic Engineering (TE) characteristics satisfying a certain Service
   Level Agreement (SLA).  This is achieved 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.

   Additionally, 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.
