Hi WG,

The version 04 of TQF mechasnim mainly includes the following updates:

1. Supplement PIFO based timeslot scheduling.
2. Simplify the timeslot mapping relationship to reduce maintenance and advertisement costs.
3. Clarify the forwarding states related with ideal position mantained on the network entry, and the relevant processing based on actual position.
4. Fix the latency equation per-hop and E2E.
5. Supplement in-time scheduling mode.
6. Update the evaluation table.
7. Supplement  security considerations.

We appreciated your any comments and suggestions.

Regards,
PSF (on behalf of co-authors)

Abstract:
 
   IP/MPLS networks use packet switching (with the feature store-and-
   forward) and are based on statistical multiplexing.  Statistical
   multiplexing is essentially a variant of time division multiplexing,
   which refers to the asynchronous and dynamic allocation of link
   timeslot resources.  In this case, the service flow does not occupy a
   fixed timeslot, and the length of the timeslot is not fixed, but
   depends on the size of the packet.  Statistical multiplexing has
   certain challenges and complexity in meeting deterministic QoS, and
   its delay performance is dependent on the used queueing mechanism.
   This document further describes a generic time division multiplexing
   scheme in IP/MPLS networks, which we call timeslot queueing and
   forwarding (TQF) mechanism.  It aims to bring timeslot resources to
   layer-3, to make it easier for the control plane to calculate the
   delay performance based on the timeslot resources, and also make it
   easier for the data plane to create more flexible timeslot mapping.
   The functions of TQF can better meet large scaling requirements.
