       Compute First Networking (CFN) Scenarios and Requirements
                      draft-geng-rtgwg-cfn-req-00

Abstract

   Service providers are exploring the edge computing to achieve better
   response times and transfer rate by moving the computing towards the
   edge of the network in scenarios like 5G MEC, virtualized central
   office, etc. Providing services by sharing computing resources from
   multiple edges is emerging. The service nodes from multiple edges
   normally have two key features, service equivalency and service
   dynamics. When the computing resources attached to a single edge site
   is overloaded, static service dispatch can possibly keep allocating
   the service request to it and cause inefficient utilization. The
   service request to edge computing needs to be dispatched to and
   served by the most suitable edge to improve user experience and
   system utilization by taking both the available computing resources
   and network conditions into account.  

   This draft describes scenarios and requirements of Compute First
   Networking (CFN) to make the computing and network resource to be
   considered in a collaborative way to achieve a more balanced network-
   based distributed service dispatching.

1.  Introduction

   Edge computing aims to provide better response times and transfer
   rate by moving the computing towards the edge of the network. Edge
   computing can be built on industrial PCs, embedded systems, gateways
   and others. They are put close to the end user. There is an emerging
   requirement that multiple edge sites (called edges too in this
   document) are deployed at different locations to provide the service.
