چکیده

This paper revisits basic message response time analysis of controller area network (CAN). We show that existing message response time analysis, as presented in [10], is optimistic. Assuming discrete scheduling, the problem can be resolved by applying worst-case response time analysis for fixed-priority non-preemptive scheduling (FPNS) as described in [4].

Calculating Controller Area Network (can) Message Response Times

Controller Area Network (CAN) is a well designed communications bus for sending and receiving short real-time control messages at speeds of up to 1Mbit/sec. One of the perceived drawbacks to CAN has been the inability to bound accurately the worst-case response time of a given message (i.e. the longest time between queueing the message and the message arriving at the destination processors). Th...

Response-Time Analysis of Mixed-Type Controller Area Network (CAN) Messages

The existing response-time analysis of Controller Area Network (CAN) can compute the response times of CAN messages that are queued for transmission periodically or sporadically. However, there are a few high level protocols for CAN such as CANopen and Hägglunds Controller Area Network (HCAN) that support the transmission of mixed messages as well. A mixed message can be queued for transmission...

Integrating Inaccessibility in Response Time Analysis of CAN Networks

Controller Area Network (CAN) is a fieldbus network suitable for small-scale Distributed Computer Controlled Systems, being appropriate for transferring short real-time messages. Nevertheless, it must be understood that the continuity of service is not fully guaranteed, since it may be disturbed by temporary periods of network inaccessibility [1]. In this paper, such temporary periods of networ...

Probabilistic Scheduling Guarantees under Error Bursts in Controller Area Network (CAN)

Dependable communication is becoming a critical factor due to the pervasive usage of networked embedded systems that increasingly interact with human lives in many real-time applications. However, these systems are often subject to faults that manifest as error bursts and affect the timing properties of the messages used in the communication. Controller Area Network (CAN) has gained wider accep...

Extending Response-Time Analysis for Mixed Messages with Offsets in Controller Area Network

The existing offset-aware response-time analysis of Controller Area Network (CAN) for mixed messages has certain practical limitations. It is based on the assumption that the jitter and deadline of a message are smaller or equal to the transmission period. However, practical systems may contain messages with release jitter greater than the period. Consequently, the deadlines specified for such ...
