Discussion
Assertion (A): Partitioning must be demonstrated where functions of differing criticality share one network.
Reason (R): A fault in one function could otherwise corrupt or starve another.
Select the correct answer from the options below.
Answer: A
Correct answer: Both A and R are true, and R is the correct explanation of A
Both are true and the second is the whole reason partitioning must be shown. Where a flight-critical function and a lower-criticality one share a medium, a fault in the latter could flood the network and delay the former, or corrupt data it depends on.
On AFDX the demonstration rests on traffic policing at the switches: a babbling end system has its excess frames discarded at the first switch, so the fault is contained where it arises. Without such a mechanism the shared medium could not be certified at all.
