Interoperability of End to End Quality of Service (QoS) Management across Heterogeneous Platforms in System of Systems

Interconnectivity, interoperability, evolution and emergent behavior are some of the key characteristics of system of systems (SOS). Providing end to end quality of service (QoS) for an SOS is a major challenge today because of issues with connectivity, the independent evolution of component systems and their heterogeneity. Heterogeneity of systems is common because of the independent evolution paths and development cycles of the systems. In this paper, we describe an interoperable end to end QoS management solution including concepts, architecture, prototype, and experimental results. Our solution not only provides QoS at systems level, but also ensuring end-to-end QoS across heterogeneous systems at the SOS level. To validate our solution, we analyzed and compared architecture alternatives and developed prototype and experiments employing multiple and varied data dissemination technologies.
