The necessity to keep acceptable service quality levels in IP networks is undeniable
nowadays, particularly with the improvement of the next generation networks. This promotes …

The traffic management of IP networks faces increasing challenges, due to the occurrence of
sudden and deep traffic variations in the network, which can be mainly attributed to the large …

Network and service performance measurements are essential in IF (Internet Protocol)
networks, eg, for network management, network monitoring, and service quality assurance …

IP Networks for both ISPs and final users. Active measurement represents an efficient mean
of evaluation and an alternative to the important infrastructure investment needed for …

This paper presents a simple prototype implementation of a performance monitoring system
for IP networks that applies both active and passive methods. The method is based on an …

With the constantly growing usage of the Internet, the need for deployment of value-added IP
services has recently yielded a dramatic investigation effort in the field of IP traffic …

The growing diversity of services in the Internet is motivating research to improve
measurability of traffic and Internet performance. This paper surveys current projects and …

Synthetic or active measurements are often used to characterize IP performance; however, it
is rare to find them used to resolve problems in an operational setting. We show that the …

Measurements and simulations are the main tools for studying the performance of IP
networks. Furthermore, active measurement techniques are becoming an integral part of …

This paper applies a new methodology for analyzing and interpreting IP metrics collected by
active measurement to loss traces aggregated on the Internet. This new approach is based …
