What makes an Avionics bus: The important factors of avionics
buses include; Deterministic behavior, Fault tolerance, and Redundancy.
Most avionics buses are serial in nature. A serial bus using only a few
sets of wires keeps the point to point wiring and weight down to a
minimum.
MIL-STD-1553 (rev B) is the best known military example, having
been developed in the 1970s.
The trend seems to be moving to Fiber buses,
MIL-STD-1773 being the fiber version of 1553.
Switched fabric networks
are used to provide Fault tolerance....
