Internet-Draft draft-ietf-detnet-nscore-00.txt is now available. It is a work

Title: On-time Forwarding with Non-work Conserving Stateless Core Fair Queuing
Authors: Yeoncheol Ryoo

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 [draft-ietf-detnet-dataplane-taxonomy-03].
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 between ET and 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 compute ET and FT based on metadata received via
packet headers. This mechanism is called non-work-preserving
stateless fair queuing, which guarantees both E2E latency upper and
lower bounds.
