Understanding the nature of traffic in high-speed communication systems is essential for achieving QoS in these networks. A first step towards this goal is understanding how basic QoS mechanisms work and affects the network predictability before we introduce more complex mechanisms such as admission control. In this paper we analyse the effect of a DiffServ inspired QoS concept applied to virtu...

In this paper the initial ideas about managing quality of service in Differentiated Services networks with help of Bandwidth Brokers have been presented. The results of simulations of how a possible signalling traffic would affect the behaviour of other data streams have been included.

A Web service is a software interface that describes a collection of operations that can be accessed over the network through standardized messaging. Effective performance and quality measures of Web services on Web service electronic marketplaces should include both technical and business aspects and consider Web services as business services delivered through multiple channels. In this resear...

This document is a preliminary specification of the IPv6 Quality of Service (QoS) tests that will be carried out by the various partners in 6NET. We describe the QoS testbed infrastructures of the various partners and the tests that will be performed. The majority of the tests will be concerned with the provision of Differentiated Services both within the partner networks and between partner ne...

Preventing unintended pregnancies and preserving sexual and reproductive health are of fundamental importance for both public and individual health and well being. Control of fertility is complex (with parenting, education, youth culture, social conditions, and economic circumstances all playing a part), and the provision of effective contraceptive services are obviously important. The task of ...
