Definitions
- a TDMA round the nodes A, B, C, D can send a message, for example an arbitration message NA1, NA2, NA3, NA4, in the C slots assigned to them.
- a TDMA round is followed by another TDMA round, in which the nodes A, B, C, D can transmit further messages.
- a bus guardian BGU is understood to mean a mechanism which, independently of a network node A, B, C, D which carries out a data transmission, monitors the correct execution of this data transmission.
- the task and purpose of a bus guardian BGU is to prevent the (temporal) transmission behavior of other network nodes A, B, C, D from being disturbed when an error occurs in one of the network nodes A, B, C, D.
- the Bus Guardian BGU can thus be used to limit the error in the transmission of messages between network nodes A, B, C, D. With the help of the Bus Guardian BGU, the "Babbling Idiot Failure" mentioned at the beginning can be avoided.
- each network node that takes part in the arbitration already has a C slot entered in the "Membership Vector", which can be used to reserve one or more NC slots. It can but it should also be desirable that non-critical nodes, to which no C slot is assigned, are allowed to send in an NC slot.
