Equivalent bandwidth control for the mapping of quality of service in heterogeneous networks

There are several QoS technologies available for an Internet service provider to manage guaranteed performance services in a telecommunication network. The study of the possible interactions between the different QoS technologies is currently an open area of research often called, in the literature, QoS mapping. A QoS mapping problem arises when different encapsulation formats are employed to support a fixed QoS with different transport technologies (e.g., ATM, IP). We face this problem in terms of bandwidth management. We adopt a novel control scheme that does not need any closed-form formula for the performance metric and that is able to react to traffic changes.
