In order to meet stringent performance requirements, system administrators must effectively
detect undesirable performance behaviours, identify potential root causes, and take …

Several new architectures have been developed for supporting multimedia applications
such as digital video and audio. However, quality-of-service (QoS) routing is an important …

Increased popularity and wealth-creation potential of conventional mobile phones, smart
phones and tablet computers resulted in the unprecedented penetration of wired and …

In a packet network, the terms bandwidth and throughput often characterize the amount of
data that the network can transfer per unit of time. Bandwidth estimation is of interest to users …

This paper presents pathChirp, a new active probing tool for estimating the available
bandwidth on a communication network path. Based on the concept of “self-induced …

Available bandwidth estimation is useful for route selection in overlay networks, QoS
verification, and traffic engineering. Recent years have seen a surge in interest in available …

The packet pair mechanism has been shown to be a reliable method to measure the
bottleneck link capacity on a network path, but its use for measuring available bandwidth is …

The available bandwidth (avail-bw) in a network path is of major importance in congestion
control, streaming applications, quality-of-service verification, server selection, and overlay …

The available bandwidth (avail-bw) in a network path is of major importance in congestion
control, streaming applications, QoS verification, server selection, and overlay networks. We …

TCP congestion control has been designed to ensure Internet stability along with fair and
efficient allocation of the network bandwidth. During the last decade, many congestion …
