Opis

The Internet has evolved from an academic network for data applications such as le transfer and net news, to a global general-purpose network used for a variety of different applications electronic mail, voice over IP, television, peer-to-peer le sharing, video streaming and many more. The heterogeneity of applications results in rather different application requirements in terms of bandwidth, delay, loss, etc. Ideally, the underlying network supports Quality-of-Service parameters such that - plications can request the desired services from the network and do not need to take actions by themselves to achieve the desired communication quality. Initially, the Internet was not designed to support Quality of Service, and only in the last decade have appropriate mechanisms been developed. Those mechanisms operate mainly on theInternetProtocol(IP) level, butalso network-speci cmechanisms e. g., targeted to particular wired/wireless access network technologies are required. The goal of the European 6th Framework Programme (FP6) Integrated Project End-to-end Quality of Service Support over Heterogeneous Networks (EuQoS) was to develop, implement and evaluate concepts and mechanisms to support QoS end-to-end, meaning that QoS mechanisms in end systems, access networks, inter- main links and within domains must be supported. The EuQoS project developed an impressiveset ofinnovativesolutionsandnovelscienti cideastosupportend-to-end QoS on the Internet. New mechanisms and concepts were designed and implemented in a European-wide distributed testbed. In addition to the rather technical design and implementation work, the project also developed training material introducing basic QoS mechanisms and techniques."

Recenzje

From the reviews:

"This book is a collection of papers that deal with various aspects of QoS protocols. This is a very technically sophisticated presentation for the technically sophisticated reader. The book begins with a series of four chapters that discuss QoS basics, including requirements, architectures, measurements, traffic engineering, and signaling models. ... This book is a fascinating read for the technically minded." (Charles K. Davis, ACM Computing Reviews, December, 2009)

The book presents mechanisms, protocols, and system architectures to achieve end-to-end Quality-of-Service (QoS) over heterogeneous wired/wireless networks in the Internet. Particular focus is on measurement techniques, traffic engineering mechanisms and protocols, signalling protocols as well as transport protocol extensions to support fairness and QoS. It shows how those mechanisms and protocols can be combined into a comprehensive end-to-end QoS architecture to support QoS in the Internet over heterogeneous wired/wireless access networks. Finally, techniques for evaluation of QoS mechanisms such as simulation and emulation are presented.

The book is aimed at graduate and post-graduate students in Computer Science or Electrical Engineering with focus in data communications and networking as well as for professionals working in this area.
