Quality of Service White Papers
On Detecting Service Violations and Bandwidth Theft in QoS Network Domains
Overview The authors design and evaluate a simple and scalable system to verify Quality of Service (QoS) in a differentiated services domain. The system uses a distributed edge-to-edge monitoring approach with measurement agents collecting information about delays, losses and throughput, and reporting to a Service Level Agreement Monitor (SLAM). The SLAM detects potential service violations, bandwidth theft, denial of service attacks, and flags the need to re-dimension the network domain or limit its users. Measurements may be performed entirely edge-to-edge, or the core routers may participate in logging packet drop information. The authors compare the core-assisted and edge-to-edge schemes, and extend network tomography-based loss inference mechanisms to cope with different drop precedence in a QoS network.
