Design and implementation of a Secure Bandwidth Broker Discovery Protocol

Abstract

Differentiated Services architecture definition lacks control level functionalities. One of the solutions proposed to fill this gap is Bandwidth Brokers (BB). Bandwidth Brokers are autonomous entities inside a network which is responsible for bandwidth management of the network along with other tasks. There is a lack of protocol for Bandwidth Brokers to discover other Bandwidth Brokers automatically. This study introduces a new Secure Bandwidth Broker Discovery Protocol (BBDP), which allows Bandwidth Brokers to automatically discover other Bandwidth Brokers. In this paper design principles, protocol details, working scenarios and implementation details of the BBDP protocol are presented. (C) 2011 Elsevier B.V. All rights reserved.
