Abstract:

   Computing-Aware Traffic Steering (CATS) optimizes traffic forwarding
   by considering both computing and networking metrics.  While existing
   framework and metric definition drafts provide theoretical models
   (e.g., L1/L2 normalized metrics), they face significant challenges in
   achieving direct operational execution in real-world deployments.
   Normalization methods vary across providers, and aggregated unitless
   scores often lose critical operational information, making it
   difficult for routers to make precise traffic-steering decisions.

   This document fills this gap by providing an executable operational
   approach.  It defines a set of Computing Service Metrics and their
   operations under the CATS framework.  Instead of transmitting low-
   level raw hardware metrics, service sites dynamically evaluate and
   report service-oriented metrics (e.g., Global Available Slots) to the
   control plane.  The document clarifies how such service-oriented
   metrics can be derived from basic resource information, service
   reference information, and local policy.  It also specifies how the
   CATS Path Selector (C-PS) combines the Computing Service
   Table (derived from C-SMA reports) with the Network Service Table to
   make joint traffic-steering decisions.  Finally, the document defines
   update control mechanisms for large-scale deployments.  This enables
   efficient and precise traffic-steering policies without negating the
   value of existing normalized metrics.
