A majority of real-time systems facesdemands for changes during their lifetime: environment and controlledprocesses undergo different operational modes and reliability requirements,process improvements necessitate modification of parts of the real-time systemsitself, equipment is repaired or upgraded. Totally pre-designed systems, as iscurrently prevalent, cannot address such changes in an effective way.
This project proposes a âself-evolvingsystemsâ approach to handle such changes. The approach is based on twobasic principles: evolutionary nature and separation between servicesand server. Services broadcast admission requests to servers, and assignthemselves to servers with positive reply. Service requests include processing,networking, and reliability demands. A server is added by connecting to thenetwork, listening, and accepting services. Should a server node be removed orfail, its services reassign themselves. In an initialization phase, aguaranteed core of services can be configured, allowing for a tradeoffbetween determinism and flexibility. As servers and services interact forassignment via service demands and local server admission, the system can be heterogeneous.
The system evolves and parts of the system and processes can be replaced or modified.
