A Process Membership Service for Active Safety Systems
Journal article, 2008

This paper describes a process membership protocol for distributed real-time systems that use both timetriggered and event-triggered message passing for communication between its processing nodes (ECUs). TTCAN and FlexRay are examples of communication networks that support such systems. The membership protocol supports redundancy management in architectures where distributed applications such as braking, stability control, and collision mitigation share a common set of processing nodes. We assume that each such application consists of several processes executing on different nodes and that each node executes processes belonging to different applications. The protocol allows a group of co-operating processes to establish a consistent view of each other’s operational status, i.e. whether they function correctly or not.
