The IESG has received a request from the Computing-Aware Traffic Steering WG
(cats) to consider the following document: - 'Computing-Aware Traffic
Steering (CATS) Problem Statement, Use Cases,
   and Requirements'
  <draft-ietf-cats-usecases-requirements-10.txt> as Informational RFC

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-call@ietf.org mailing lists by 2025-12-17. Exceptionally, comments may
be sent to iesg@ietf.org instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.

Abstract


   Distributed computing is a computing pattern that service providers
   can follow and use to achieve better service response time and
   optimized energy consumption.  In such a distributed computing
   environment, compute intensive and delay sensitive services can be
   improved by utilizing computing resources hosted in various computing
   facilities.  Ideally, compute services are balanced across servers
   and network resources to enable higher throughput and lower response
   time.  To achieve this, the choice of server and network resources
   should consider metrics that are oriented towards compute
   capabilities and resources instead of simply dispatching the service
   requests in a static way or optimizing solely on connectivity
   metrics.  The process of selecting servers or service instance
   locations, and of directing traffic to them on chosen network
   resources is called "Computing-Aware Traffic Steering" (CATS).

   This document provides the problem statement and the typical
   scenarios for CATS, which shows the necessity of considering more
   factors when steering traffic to the appropriate computing resource
   to better meet the customer's expectations.
