DIONASYS: Declarative and Interoperable Overlay Networks, Applications to Systems of Systems
| Responsable du projet | Etienne Rivière |
| Résumé |
An increasing number of different kinds of resources, including
everyday objects, are interconnected to each other. Some analysts
estimate that around 50 billions of devices should be
interconnected at the horizon of 2020. This paves the way for new
large-scale systems, and requires the need for novel architectures
and design principles to support such a scale. Further, these
resources may be very different at both the hardware and software
layer, in terms of both functional and non-functional properties.
This will lead to system of systems that federate highly
heterogeneous distributed systems as already illustrated, for
instance, by environmental and earth observation systems. Designing
such large, interconnected and heterogeneous systems is a daunting
task. A possible way to overcome the complexity of contemporary
distributed systems is to leverage overlay networks and their
higher level of abstraction. The virtualization of the underlying
network resources allows providing a range of reusable network
services. Many types of overlay networks have been proposed and
developed in the previous years for a variety of networked systems,
applications and services. However, the design and development of
overlays remains a complex task, especially when dynamic
adaptation, large-scale interoperability and composition are
required. Adding interoperability, adaptation and composition
capabilities often require huge and complex re-engineering of
existing overlay implementations. In the context of overlay
networks, it also requires appropriate abstractions and runtime
support for allowing different type of overlays and structures to
be linked, cooperate and provide adaptive interoperable end-to-end
services in a dynamic fashion. In this project, we propose to raise the level of abstraction provided to designers of overlays and systems-of-systems. To this end, we are using a generative language approach to overlay design and composition. We will provide the corresponding new programming models, abstractions and tools. Our aim will be reached via the use of a high-level domain- specific language, declaring what should be achieved for the structure and functions of overlays, rather than by defining low-level nodes interactions. The proposed approach will be supported by a dedicated runtime implemented in a distributed systems development and deployment framework. The project follows a prototype-driven approach. It will feature a large-scale demonstrator linking heterogeneous overlays —networked systems and sensor networks—in an integrated manner, with support for adaptive and malleable end-to-end services and functionalities. |
