Schedulability Analysis of GMF-Modeled Messages over Controller Area Networks with Mixed-Queues

Conference/Workshop Paper

10th IEEE International Workshop on Factory Communication Systems
Abstract
The Controller Area Network (CAN) is widely
utilized in many industrial real-time applications. As a real-time
communication network, the predictability of timing behaviors
is very important. Therefore, many works have been proposed
regarding the schedulability analysis of CAN messages. Most
of the existing analysis approaches are based on a traditional
periodic message model. However, in some applications, the
transmission of a message may follow a certain pattern instead
of repeating the same transmission period by period. In these
cases, applying the existing analysis methods may lead to quite
pessimistic results. In order to tackle this problem, in this paper
we apply the Generalized Multi-Frame (GMF) task model on
CAN messages, where both priority-based and FIFO-based message
queues are taken into account. We present a corresponding
sufficient schedulability analysis. According to the experimental
evaluations, our analysis can provide tighter results compared to
the existing CAN message response time analysis in the context
of GMF-modeled messages.
