 5G End-to-end Network Slice Mapping from the view of Transport Network
                draft-geng-teas-network-slice-mapping-00

Abstract

   Network Slicing is one of the core featrures in 5G.  End-to-end
   network slicing consists of 3 major types of network segments: Access
   Network (AN), Mobile Core Network (CN) and Transport Network (TN).
   This draft describes the procedure of mapping relationship between 5G
   end-to-end network slice into and transport network slice defined in
   IETF.  This draft also intends to expose some gaps in the existing
   network management plane and data plane to support inter-domain
   network slice mapping.  Further work may require cooperation between
   IETF and 3GPP (or other standard organizations).  The definition of
   data model, signaling protocol extension and new encapsulation is out
   of the scope of this draft.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

1.  Introduction

   Driven by the new applications of 5G, the concept of network slicing
   is defined to provide a logical network with specific network
   capabilities and network characteristics.  Network slice contains a
   set of network functions and the required resources(e.g.
