              Framework of Compute First Networking (CFN)
                    draft-li-rtgwg-cfn-framework-00

Abstract

   Compute First Networking (CFN) leverages both computing and
   networking status to help determine the optimal edge among multiple
   edge sites with different geographic locations to serve a specific
   edge computing request. Requests for the same service can be
   determined and dispatched to different edges based on service
   requirements, network and computing resource conditions and other
   factors to achieve better load balancing and system efficiency. The
   request needs to be dispatched to the selected edge in real time and
   the subsequent packets from the same flow should be served by the
   same edge for flow affinity. This document describes a framework of
   CFN to achieve the desired features.

1. Introduction

   Compute First Networking (CFN) scenarios and requirements document
   [CFN-req] shows the usage scenarios that require an edge to be
   dynamically selected from multiple edge sites with different
   geographic locations to serve an edge computing request based on
   computing resource consumption and network status in real time. For
   instance, edge site in residential area receives low request volume
