Title : Marking behaviour of PCN-nodes
Author(s) : P. Eardley
Filename : draft-ietf-pcn-marking-behaviour-02.txt
Pages : 20
Date : 2009-03-05
This document standardises the two marking behaviours of PCN-nodes:
threshold marking and excess traffic marking. Threshold marking
marks all PCN-packets if the PCN traffic rate is greater than a
configured rate ("PCN-threshold-rate"). Excess traffic marking marks
a proportion of PCN-packets, such that the amount marked equals the
traffic rate in excess of a configured rate ("PCN-excess-rate").
Setting the configured rates below the physical link rates enables
PCN-nodes to provide information to support admission control and
flow termination in order to protect the quality of service of
established inelastic flows.
