In recent past, to rectify certain limitations of bus-based “Shared-Clock” (SC) architectures we have developed two new SC protocols based on star topology. In both bus and star-based designs, the Controller Area Network (CAN) protocol was used for network communications. Previously we have demonstrated that both new protocols in their individual capacities have the potential for addressing issues relating to Time-Triggered Cooperative (TTC) scheduling, Time Triggered bus-based CAN networks and the Single Point of Failure (SPF) hypothesis in star networks. In this paper, we present a mechanism for integrating the properties of both protocols in one. We present an amalgamation of protocols that result in a new protocol which addresses all the above stated issues on a single platform.
