Evaluation of Bandwidth Broker Signaling

چکیده
The Differentiated Service (DiffServ) architecture for the Internet implements a scalable mechanism for quality-of-service (QoS) provisioning. Bandwidth brokers represent the instances of the architecture, that automate the provisioning of a DiffServ service between network domains. Although several bandwidth broker implementations (e.g. [Bri98]) have been proposed, the alternatives and trade-offs of the different viable approaches of inter-broker communication were not studied up to now. This paper presents the broker signaling trade-offs considered in the context of a DiffServ scenario used by the Swiss National Science Foundation project CATI [SBGP99], and it presents results gathered by simulations.

Architectures and performance evaluation of bandwidth brokers
DiffServ is the basis of contemporary QoS-enabled networks. Setting up DiffServ QoS requires extensive engineering effort in dimensioning and provisioning, especially for adjacent networks under different administrations linked in a “federated” hierarchy. The bandwidth broker is an entity that is responsible for the management of the resources and the QoS service operation in an automated way. ...
متن کاملProviding Differentiated Services to Mobile IP Users
To support Quality-of-Service (QoS) provisioning in highly dynamic mobile environments, we propose a signaling protocol allowing mobile users to contact a Differentiated Services bandwidth broker for QoS negotiation. The protocol can also be used for QoS negotiations between bandwidth brokers.
متن کاملClass of Service Concepts in Autonomous Systems
The bandwidth broker architectures introduced to manage diffserv still have scalability flaws in the mean of large volumes of end-to-end tunnels and workload they have to handle. In addition they only provide solutions of inter-domainmanagement and do not consider the characteristics of intra-domain-management. The new signaling approach for intra-domain-management presented in this paper utili...
متن کاملQoS Provisioning for Mobile IP Users
In wireless access networks bandwidth is a limited resource. Therefore, Mobile IP users will demand to receive QoS support. However, in a highly dynamic environment — as mobile environments — QoS provisioning is a difficult task. In this paper we propose a signaling protocol for mobile users to contact a bandwidth broker for negotiation QoS for a flow. This protocol can also be used for negotia...
متن کاملDesign and evaluation of a bandwidth broker that provides network quality of service for grid applications
The term computational Grid is used to describe a problem solving environment in which geographically and organizationally dispersed resources are integrated into a common infrastructure. Building computational Grids requires the existence of a resource management framework that provides a unique and secure interface to the reservation and allocation capabilities offered by the various local re...
