BIBLIOGRAPHY Abstract
Provides an architectural framework for support of Quality of Service (QoS) in packet networks. Central to the architectural framework is a set of generic network mechanisms (or QoS building blocks) for controlling the network service response to a service request, which can be specific to a network element, or for signalling between network elements, or for controlling and administering traffic across a network.
