Abstract:

   Geographically distributed compute-intensive services require
   coordinated selection of execution sites and wide-area traffic paths.
   Placement changes slowly because service relocation may involve model
   loading, state migration, or execution-environment reconfiguration,
   while traffic splitting can be changed more frequently.

   This document evolves the CATPTS framework by defining a timescale-
   aware control architecture for source-compute-destination services.
   A slow-timescale placement function uses abstracted multipath and
   failure information to select a compute site.  A fast-timescale
   traffic function then refines the input and output traffic
   allocations across candidate paths while holding placement fixed.

   The framework also introduces scenario-based service-loss estimation
   and an optional Conditional Value at Risk (CVaR) policy for limiting
   tail loss caused by compute-site or network-link failures.  This
   document specifies architectural principles, information
   requirements, workflows, and operational considerations; it does not
   specify protocol extensions or a mandatory optimization algorithm.
