Quality of Service is a fast growing area of technology, being driven by the growth of real-time applications such as voice over IP. This book is perfect for the technical professionals who are looking for information building blocks of Quality of Service and who need to grasp critical concepts such as the DiffServ and IntServ models and the use of MPLS to support the next generation of VPNs. Network architects, network engineers, and network designers will use the authoritative guide to understand the different emerging technologies that can be used to archive Quality of Service, and to decide how to incorporate them into their networks and meet the needs of their particular network environment. Quality of Service in IP Networks presents a great deal of technical detail, as well as provides a clear understanding of the architectural issues surrounding delivering QoS in an IP network, and its positions in the emerging technologies within a framework of solutions.
