A Middleware Solution for the Support of QoS for Legacy Applications

The evolution of quality of service mechanisms in the Internet is prominent nowadays. The Integrated and Differentiated services, along with the evolving Bandwidth Broker concept complement each other to offer the required quality. One significant aspect towards this direction is the capability for users and applications to convey their QoS requests to the core network entities. This paper discusses a middleware architecture that seamlessly supports legacy nonQoS-aware applications to take advantage of the quality provisions. The proposed middleware can also leverage existing QoS-aware or newborn applications. It is destined to cooperate with the QoS management entities of the Aquila architecture in the access and core networks, even though it can also be used in conjunction with existing architectures.
