Discussion
Arrange these steps by which a frame crosses an avionics Ethernet network:
1. The end system queues the frame on its virtual link
2. The bandwidth allocation gap is observed before transmission
3. The frame is switched towards its destinations
4. Redundant copies arrive over both networks
5. The receiving end system discards the duplicate
Select the correct sequence.
Answer: B
Two independent networks carry every frame, and the receiver keeps the first copy to arrive. Redundancy management at the end system is what turns two ordinary networks into one reliable path. The first copy to arrive wins.
