        Review of Network Slicing Research in Diverse Standards
          draft-wang-nfvrg-network-slice-diverse-standards-00

Abstract

   As one of the significant technology in 5G, there are diverse
   industry communities and standard organizations dedicated in a
   research of Network Slicing, such as IETF, 3GPP, GSMA, ETSI, etc..
   These organizations and communities not only standardize network
   slicing architecture, management, requirements and so on, but also
   individually focus on specifying network slicing in their own ways,
   offering diverse specifications of it.  Aiming at research on a
   overall review of network slicing standard, this document discuss
   diverse standards in various organizations and communities,
   furthermore, analyzing the emphasis and difference between them.

1.  Introduction

   With the rapid development of 5G technology research and successful
   emergence of 5G market, network slicing is becoming one of
   significant technologies of 5G.  The mechanism of network slicing is
   that divide common physical network infrastructure into diverse
   isolated virtual network resources to meet the high level demands
   from different vertical industry.  With network slicing, providers
   are able to offer customized service to users in terms of bandwidth,
   latency, security and so on.  Network slicing mechanism enables 5G to
   integrate diverse network resources and multi-domain technologies, to
   meet various demands from vertical industry, offering the best-effort
   network service.  For instance, to achieve both determined latency
   and security requirements from some industry services, network
   slicing is likely to apply TSN[tsn] and blockchain technologies to
   satisfy the requirement.  Meanwhile, network resources such as high
   bandwidth and dedicated network tunnel can be supplied here to meet
   the demands as well which are all integrate in this network slice.

   As the key feature of 5G, the concept of network slicing is discussed
