Response time analysis for mixed messages in CAN supporting transmission abort requests

Abstract

Abstract-The existing response-time analysis for messages in Controller Area Network (CAN) with CAN controllers facilitating transmission abort requests in transmission buffers does not support mixed messages. The existing analysis assumes that a message is queued for transmission either periodically or sporadically. However, a message can also be queued both periodically and sporadically using a mixed transmission mode implemented by several high-level protocols for CAN used in the industry today. We extend the existing analysis for mixed messages in CAN which is generally applicable to any high-level protocol that uses periodic, sporadic and mixed transmission modes and supports transmission abort requests in CAN controllers.

Extending response-time analysis of mixed messages in CAN with controllers implementing non-abortable transmit buffers

“…We presented the work in progress on the extension of the existing analysis to support mixed messages in CAN network where CAN controllers do not support transmission abort requests in the transmit buffers. Once the analysis is fully developed, we will combine it with the analysis of mixed messages in CAN supporting transmission abort requests [17] in the longer version of this paper. We plan to implement the extended analysis in the existing industrial tool suite (Rubus-ICE) and conduct the industrial case study (discussed in Section 1.2).…”

“…In [16], Mubeen et al developed offset-set aware analysis for mixed messages in CAN. In [17], Mubeen et al extended the existing RTA for mixed messages in CAN with controllers supporting transmission abort requests in transmit buffers. However, none of the above RTA for mixed messages support non-abortable transmit buffers in CAN controllers.…”
