Dear IDR WG,We are pleased to announce that an updated version of the draft-yi-idr-bgp-fs-edge-service-metadata-05 has been submitted. This revision incorporates valuable feedback and suggestions from the 124th CATS WG discussions, including:
 1.CATS work background: Added detailed use cases and operational requirements for Computing-Aware Traffic Steering, providing clearer context for the proposed mechanisms.
 2. Metric references: Expanded content on L2 normalized metrics, aligning with CATS metric definitions to enhance technical consistency.
This draft addresses the CATS WG's focus on distributing compute metrics and steering traffic for improved service performance. We warmly welcome any suggestions, comments, or discussions to further refine the draft. Your insights are highly appreciated.Best regards,
Xinxin

Abstract:

   In edge computing and distributed cloud environments, a service may
   be deployed on multiple instances across one or more sites, referred
   to as edge service.  The edge service is typically associated with an
   ANYCAST IP address.  With the emergence of Computing-Aware Traffic
   Steering (CATS) requirements, there is a growing need to consider
   both network and computing metrics when making traffic steering
   decisions.  Traditional routing protocols lack the capability to
   convey compute-related information, necessitating extensions to
   existing protocols.

   This draft defines a mechanism to distribute service routes along
   with computing-related metadata using BGP FlowSpec.  The service
   metadata, including compute resource status and performance metrics,
   can be collected by a central controller, processed, and then
   distributed to ingress routers using BGP FlowSpec extensions.  This
   enables ingress routers to make path selections based not only on
   routing cost but also on the running environment and resource
   availability of edge services, thereby optimizing Quality of
   Experience (QoE).
