Abstract:

   This document specifies the framework and operational procedure for
   deterministic networking that guarantees maximum and minimum end-to-
   end latency bounds to flows.  The solution has non-periodic,
   asynchronous, flow-level, non-work conserving, on-time, and rate-
   based functional characteristics, according to the taxonomy suggested
   by [I-D.ietf-detnet-dataplane-taxonomy].

   The packets are stored in the queue in ascending order of the ideal
   service start time, called Eligible Time (ET), and the ideal service
   completion time, called Finish Time (FT).  The queued packets were
   forwarded after ET, in ascending ordering of FT, in a non-work
   conserving manner.  The ET and FT are calculated at the entrance node
   according to the packet size and rate of the flow.  All subsequent
   core nodes are stateless and asynchronously update ET and FT based on
   metadata received via packet headers.  This mechanism is called non-
   work conserving stateless fair queuing (N-SCORE), which guarantees
   both E2E latency upper and lower bounds, thus E2E jitter bound.
