Framework for Binding Access Control to COPS Provisioning

This document outlines a framework for binding access control to COPS (Common Open Policy Service) provisioning, focusing on Quality of Service (QoS) management. It discusses various aspects like tunnel encapsulation, MPLS (Multiprotocol Label Switching), and classifiers for managing network traffic. The framework supports hierarchical classification and parallel session processing for efficient resource allocation across VoIP and streaming services. It provides insights into session handling, including in-profile and out-of-profile metrics, dropper mechanisms, and the integration of Hierarchical Classifiers for enhanced access management.
