In {[}I-D.taylor-cl-edge-behaviour{]}, flow termination is required if excess-traffic-marked packets were observed and the end of one measurement period MUST be the beginning of the next one, independently of current flow conditions. According to this termination, PCN-flows in some ingress-egress (IE) pairs may be terminated during measurement period of other IE pairs unless round- trip times (RTT) of all the IE pairs are the same. We illustrate that this can lead to over-termination. Our simulation confirms that accuracy of termination is improved when no PCN-flows in some IE pairs are terminated during measurement period of other IE pairs.}, }
