Requirements of computing and network joint optimization and scheduling
               draft-fu-coinrg-joint-optimization-req-00

Abstract

   With the development of edge computing, there is a trend that
   computing is widely deployed in network rather than at other end of
   network, and provides services at nearer location.  With the deep
   integration of network, traditional optimization and scheduling
   within network domain is not enough, the endpoint of the path matters
   a lot.  So the relationship between computing and network are new and
   important topics to be studied.  This document focus on the
   requirements of computing and network joint optimization and
   scheduling based on the newly arising service requirements.

1.  Overview

   For traditional services without strict service requirements, the
   best-effort network can meet the requirements with traditional path
   optimization, which only consider the network condition.  With new
   services arising, such as cloud AR/VR, cloud gaming, V2X, new and
   strict requirements towards network, also towards the service
   endpoint are proposed to meet the service requirements.  So the
   computing and network joint optimization and scheduling are proposed
   to guarantee the service performance.

   The computing and network joint optimization means that there is not
   only the path optimization in network, but also the endpoint joint
   optimization; also the two will affect each other.  Based on the
   joint optimization, the service scheduling can be performed
   considering the network condition and also the endpoint condition,
   with the "optimal path+ optimal endpoint" policy.  What's more, the
   computing and network resources joint reservation is required for
   services with strict performance requirements.
