                  Requirement of Computing in network
                    draft-liu-coinrg-requirement-01

Abstract

   New technology such as IOT, edge computing,etc. propose the
   requirement of computing in network, so convergence of network and
   computing has become a trend.  This document points out the
   requirements of computing in network according to the development of
   new Industry, including the performance, function and management
   requirements.

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.  Overview

   Intelligence in the whole industry has a huge demand for computing,
   which put forwards immense challenges to cloud computing and network.
   Network Architecture is undergoing a transformation towards cloud and
   service, providing rapid response and flexible deployment for
   different industries.  The perfomance, function and management
   requirements of network's development need to be considered.

2.  Requirements of Network

   Computing in the network has some requirements of performance,
   function and management, to ensure the operation of future business
   and user experience.

2.1.  Performance requirement

2.1.1.  Precision

   Precision of the network refers to the deterministic of latency,
   packet loss rate and computing resource.

   The traditional network's best-effort forwarding mode can no longer
   meet the demand of such services for network latency.  The
   deterministic latency brings forward a new measure latitude for
