Evaluation of a Policy-Based QoS Management Architecture over an IPv6 DiffServ testbed

In this paper we present the implementation of a bandwidth broker architecture for the centralized management of the QoS in native IPv6 DiffServ networks in a multi-domain environment. The bandwidth broker has been programmed in JAVA and uses COPS-PR as an infra-domain communication protocol and SIBBSv6 as an inter-domain communication protocol. The latter protocol is also presented. SIBBSv6 is a variation of the SIBBS inter-domain communication protocol with some new features such as the IPv6 support. The evaluation of the proposed architecture has been tested by implementing a real IPv6 DiffServ testbed composed of three domains. Each of these domains is managed by the developed bandwidth broker named BBv6. The results of these tests and the corresponding conclusions are also presented.
