Abstracr-This paper designs a detection system to measure QoS in differentiated services networks.The system detects a number of bandwidth theft and denial of service attacks.We use a distl"ibuted monitoring approach, \\lith measurement agents collecting information about the traffic characteristics at aU the nodes of a DS domain, and reporting to a central management station that performs analysis to detect possible SLA violations, bandwidth theft or denial attacks.We are implementing and testing the system on a differentiated services testbed to evaluate if we can effectively detect such attacks.OUI' system can be useful in developing mechanisms for response and damage control in QoS enabled networks.
