The term Quality of Service, abbreviated QoS, refers to network resource control mechanisms. Quality of Service is the ability to provide different priority to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow. This book brings all of the elements of network quality of service (QoS) together in a single volume, saving the reader the time and expense of making multiple purchases. It introduces network QoS, explains the basics, describes the protocols, and discusses advanced topics, by the best and brightest experts in the field. It is a quick and efficient way to bring valuable content together from leading experts in the field while creating a one-stop-shopping opportunity for customers to receive the information they would otherwise need to round up from separate sources.
- Chapters contributed by recognized experts cover theory and practice of network quality of service (QoS), allowing the reader to develop a new level of knowledge and technical expertise.
- Presents methods of analysis and problem-solving techniques, enhancing the reader's grasp of the material and ability to implement practical solutions.
- Use of examples illustrate core QoS concepts for enhanced comprehension
