TTCAN over mixed CAN/switched Ethernet architecture

Embedded systems have specific real-time requirements that led to the development of dedicated communication protocols. Such systems often face increasing communication needs and the integration of switched Ethernet architecture. But moving from existing dedicated field-buses architectures to new Ethernet based architectures is not always easily feasible, due to industrial constraints. In this paper, we propose a solution for integrating existing data busses (such as CAN, which is an important standard in automotive context) on a global architecture that respects increasing bandwidth requirements. We consider a time triggered CAN application and propose CAN/Ethernet bridging strategies that respect the time-triggered real time behaviour of CAN End System when communicating through a switched Ethernet network that can also be shared by (non CAN) applications
