PREDICTABILITY OF MESSAGE TRANSFER IN CSMA-NETWORKS
J. KAISER, Mohammad Ali Livani, W. JIA · 2000
This paper proposes an approach to realise a bus arbitration scheme which supports the coexistence of messages with different real-time requirements. It provides pre-planned time slots for HRTMs. For SRTMs, dynamic EDF-scheduling is applied. SRTMs and even non real-time messages (NRTM) can be sent any time and the scheme guarantees that they will not interfere with HRTMs. To enforce the reservations and the scheduling decisions, we devised a dynamic priority scheme presented in this paper.
