Quality of Service: IP, ATM, DiffServ, and MPLS

Quality of Service (QoS) may well be one of themost confusing and elusive topics in datanetworking today. QoS is a broadly-used termthat refers to the performance attributes of anend-to-end connection. The particular elementsof a QoS definition depend on the informationbeing transported. For example, QoS for voicedefines limits on specific parameters such asdelay, signal loss, noise, and echo. ......
