Abstract:

   Computing-Aware Traffic Steering (CATS) is a traffic engineering
   approach that optimizes the steering of traffic to a service instance
   by considering the dynamic state of computing and network resources.
   To enable such decisions, CATS components exchange metrics that
   describe resource conditions affecting service instance selection.
   This document focuses on compute and communication metrics for CATS
   and defines a hierarchical abstraction of these metrics to improve
   interoperability, scalability, and operational simplicity.  It does
   not aim to standardize raw infrastructure (Level 0) metrics; instead,
   it specifies higher-level representations that can be derived from
   raw measurements using aggregation and normalization functions.
