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 for layer-3 in an IP/MPLS networks, called timeslot queueing
   and forwarding (TQF) mechanism.  TQF is an enhancement based on TSN
   TAS and allows the data plane to create a flexible timeslot mapping
   scheme based on available timeslot resources.  It defines a cyclic
   period consisting of multiple timeslots where a flow is assigned to
   be transmited within one or more dedicated timeslots.  The objective
   of TQF is to better handle large scaling requirements.
