A recent trend in distributed computer-controlled systems (DCCS) is to interconnect the distributed elements by means of a multi-point broadcast network. As the network bus is shared between a number of network nodes, there is an access contention, which must be solved by the medium access control (MAC) protocol. Usually, DCCS impose real-time constraints. In essence, by real-time constraints we mean that traffic must be sent and received within a bounded interval, otherwise a timing fault is said to occur. This motivates the use of communication networks with MAC protocols that guarantee bounded access and response times to message requests. In this paper we analyse how the network access and queuing delays imposed by the P-NET's MAC mechanism can be evaluated in order to guarantee the real-time behaviour of the supported DCCS.
