This book poses solutions to questions related to quality of service (QoS) issues within heterogeneous network environments. The book includes a series of algorithms and protocols to help solve potential QoS problems, and information on QoS mapping in terms of service-level specifics. Case studies and operative examples illustrate the main points of the book. Coverage includes end-to-end QoS, QoS architecture, and QoS internetworking and mapping. The book is for graduate students and researchers, as well as system designers, developers, and engineers. Marchese teaches in the Department of Communications, Computer and System Science at the University of Genoa, Italy. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)

The importance of quality of service (QoS) has risen with the recent evolution of telecommunication networks, which are characterised by a great heterogeneity. While many applications require a specific level of assurance from the network; communication networks are characterized by different service providers, transmission means and implementer solutions such as asynchronous transfer mode (ATM), Internet protocol version 4 (IPv4), IPv6 and MPLS.

Providing comprehensive coverage of QoS issues within heterogeneous network environments, “QoS Over Heterogeneous Networks” looks to find solutions to questions such as does QoS fit within heterogeneous networks and what is the impact on performance if information traverses different network portions that implement specific QoS schemes.

 Includes:

  • A series of algorithms and protocols to help solve potential QoS problems.
  • State of the art case studies and operative examples to illustrate points made.
  • Information on QoS mapping in terms of service-level specification (SLS) and an in-depth discussion of related issues
  • Chapters end-to-end (E2E) QoS, QoS architecture, QoS over heterogeneous networks and QoS internetworking and mapping.

An ideal book for graduate students, researchers and lecturers. System designers, developers and engineers will also find “QoS Over Heterogeneous Networks” a valuable reference.
