Policy Approach for End-to-End QoS
Overview
The paper provides an overview of the requirements for QoS policies, the alternate policy architectures that can be deployed in a network, the different protocols that can be used to exchange policy information, and the exchange of policy information among different administrative domains.
One of the key issues in deployment of QoS is determining the set of applications or users, which are allowed to have a preferential access to network resources. The administrative criteria for regulating access to resources constitute the QoS policies. A policy could determine which of the reservation requests in the network be honored during the processing of a signaling protocol such as RSVP, or it could determine the class of applications or users which are to be placed in a specific DiffServ class of service>
In this paper, we look at the issues that arise in the definition, deployment and management of policies related to QoS in an IP network. The paper provides an overview of the requirements for QoS policies, the alternate policy architectures that can be deployed in a network, the different protocols that can be used to exchange policy information, and the exchange of policy information among different administrative domains. We provide a coverage of the current issues being examined in IETF and other standard bodies, as well as issues explored in policy related research ongoing at different universities and research labs.
