Abstract:
We detail the implementation of a network rate scheduler based on
both a packet-based implementation of the generalized processor
sharing (GPS) and a strict priority policies. This credit based
scheduler called Priority Switching Scheduler (PSS), inherits from
the standard Strict Priority Scheduler (SP) but dynamically changes
the priority of one or several queues. Usual scheduling
architectures often combine rate schedulers with SP to implement
DiffServ service classes. Furthermore, usual implementations of rate
scheduler schemes (such as WRR, DRR, ...) do not allow to efficiently
guarantee the capacity dedicated to both AF and DF DiffServ classes
as they mostly provide soft bounds. This means excessive margin is
used to ensure the capacity requested and this impacts the number of
additional users that could be accepted in the network. PSS allows a
more predictable output rate per traffic class and is a one fit all
scheme allowing to enable both SP and rate scheduling policies within
a single algorithm.

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
