Estimation Accuracy of IP QoS Measurements based on Active Traffic Probing⋅
نویسنده
چکیده
ISPs selling IP data transmission with negotiated QoS need to prove to their customers the compliance of actual transmission quality with the negotiated QoS from their contracts. For this it is necessary to monitor the quality of end-to-end connections. Whereas passive monitoring of all traffic is prohibitively expensive, active test traffic can be sent regularly between routers and/or end-systems to monitor the transmission quality. In this work we show how quality constraints for the background traffic can be derived from results of low-volume active the test probing which hold true with very high confidence.

Tuning Active Monitoring in Multi-service IP Networks
This paper explores the use of edge-to-edge active monitoring to control simultaneously multiple QoS parameters in multi-service IP networks, while reducing the effects of intrusion on real traffic. Considering a multi-class domain where traffic is controlled at network boundaries based on feedback from on-line measurements, the present work is centered on obtaining adequate per class in-band p...

State estimation in the energy management center of active distribution networks has attracted many attentions. Considering an increase in complexity and real-time management of active distribution networks and knowing the network information at each time instant are necessary. This article presents a two-step multi-area state estimation method in balanced active distribution networks. The prop...
متن کاملOn Active Measurements in QoS-Enabled IP Networks
Network monitoring applications are often used by service providers to monitor compliance with service level agreements (SLAs) made with customers and to trigger troubleshooting activities when service drops below guaranteed levels. These applications can also play a role in determining the amount of compensation service providers must give when service guarantees are not met. Many performance ...
متن کاملQueuing Delay Propagation Model (QDPM)-based Queuing Region Determination for Available Bandwidth Estimation of Multimedia QoS
Available bandwidth is an important factor that can be used to adapt the sending rate to network conditions, so that packet loss, caused by congestion, can be significantly reduced before error control mechanisms are employed. To this end, we propose an active probing-based queuing delay propagation model (QDPM)-based scheme for available bandwidth estimation. Common assumptions, including use ...
متن کاملCapacity measurement in small-scale heterogeneous best-effort IP networks
Current home networks are not well designed to support quality of service (QoS). Successfully employing current QoS solutions in heterogeneous environments, such as home networks, requires compatibility between the many possible solutions for the different network technologies. Often the solutions need support from all devices throughout the network. Additionally, it is often difficult to confi...
