چکیده

Keeping in mind the present network management research trends, it can be safely stated that in the near future enterprise networks and ISPs will need a network management entity to dynamically manage QoS networks. DiffServ is one of the emerging networks that introduces bandwidth broker as its logical resource, network and policy management module. Due to the complex and huge functionality provided by bandwidth broker, it has very large number of semi explored research areas. This survey is an effort to briefly discuss some of the developments in the ongoing process of defining and implementing a functional bandwidth broker.

Providing End-to-End guaranteed Quality of Service over the Internet: A survey on Bandwidth Broker Architecture for Differentiated Services Network

The ongoing effort by the Internet Engineering Task Force (IETF) in recent years has resulted in two technologies for support of Quality of Services (QoS) in the Internet. They are Integrated Services Network and Differentiated Services Network, commonly known as int-serv and diffserv. The scalability issue is considered as the major differentiator in the performance of these two technologies a...

On Scalable Design of Bandwidth Brokers

In this paper we study the scalability issue in the design of a centralized bandwidth broker model for dynamic control and management of QoS provisioning. We propose and develop a path-oriented, quota-based dynamic bandwidth allocation mechanism for efficient admission control operations under the centralized bandwidth broker model. We demonstrate that this dynamic bandwidth allocation mechanis...

An Admission Control and Deployment Optimization Algorithm for an Implemented Distributed Bandwidth Broker in a Simulation Environment

This paper describes and tests a distributed bandwidth broker that has been implemented in NS simulator. It focuses on the admission control algorithm, its advantages and drawbacks. Also, the bandwidth broker is tested, managing the IP Premium service and we compare 2 different implementations of the service. Finally it approaches the problem of the optimal location of a bandwidth broker in a b...

A host selection model for a distributed bandwidth broker

This paper deals with a distributed bandwidth broker that we try to evaluate and therefore propose a model that will improve its operation in a backbone network. Such a distributed bandwidth broker has been implemented and tested in NS simulator. Its operation is affected very much by the network condition and the responding time is proportional to the delay of packets in the network. Therefore...
