The CCC research unit divides into three project areas with a total of nine projects. See the project's homepage for a full overview of the organization and objectives of CCC. The research group Connected and Mobile Systems of the IBR is responsible for the subproject A2, the Communication and Interaction Platform, of CCC, the research group Distributed Systems for the subproject A3 on resource efficient dynamic agreement and replication, and the Algorithms group for subproject B1 which covers Conflict Resolution and Optimization.

Project A2: Communication and Interaction Platform

Project A2, Communication and Interaction Platform, covers the interaction of the architectural components through networks. While CCC starts with platforms using local, closed networks with single owners, A2 will move the platform challenge up to the next level of open networks. This means that the interfaces as well as the underlying networking platforms and protocols between the different components must be flexible and dynamic. Platform guarantees cannot be given at the level of single components, but only in the form of platform services provided by a distributed resource control layer. A generic and abstract access to the networking platform and its services is needed where resource demands as well as constraints are adhered to. A2 will address the general communication architecture, which shall be able to ensure safety, availability and security properties in the system. This will require instantiation configuration of the networking infrastructure to ensure contract properties, e. g. instantiation of concurrent multi-path routing mechanisms to ensure high availability communication.

Project A3: Resource efficient dynamic agreement and replication

The A3 subproject addresses a specific and refined question, namely how a set of CCC-controlled domains can be jointly reconfigured and how applications that are dispersed over multiple CCC-domains can be coordinated to establish an extended level of fault-tolerance. Thereby, faults are not limited to crashes but depending on the scenario range from hardware induced malfunctioning (e.g. bit flips) up to the extreme intentional and coordinated malicious behavior. In short such effects can be subsumed by Byzantine faults and are addressed by Byzantine fault-tolerance.
