Quality of Service is a valuable working resource for telecommunication engineers charged with solving the problem of how to handle the exploding volume of traffic on their companies' networks. The authors explore the roots of the current network traffic control crisis & they provide a realistic assessment of the gamut of standard, new, & emerging QoS/CoS technologies. They consider all crucial, design, cost, & support issues surrounding QoS deployment for all types of networks, including intranets & multimedia networks. & they provide a rational framework for finding the most cost-effective QoS/CoS solutions. This book also focuses on IP & MPLS technologies & routing protocols. Internet architecture & problems in an IP networks are illustrated when different internet protocols are used. Evaluation of QoS guarantee parameters such as delay, jitter & throughput are described with state of art study results mainly for real time applications in IP & MPLS networks. Key technical issues covered include queuing disciplines, traffic shaping, & admission control techniques, MPLS TE implementation & working, Frame Relay & ATM technologies, Integrated Services Architecture & RSVP.
