Mapping the quality of service over heterogeneous networks: a proposal about architectures and bandwidth allocation

The paper presents a general framework and some possible architecture to get a feasible QoS (quality of service) mapping among network portions that use different technologies to provide a fixed service level to the terminal users. In general, there is a strong need to have "communication" among portions implementing different QoS technologies: a proper architecture, functionalities and protocols should be defined. The current work, after stating the framework, tries to propose some architectural solutions and shows a preliminary performance investigation concerning mapping of a specific QoS parameter as bit loss among an ATM and an IP portion.
