Other problems

Traditional computational problems booty the angle that we ask a question, a computer (or a broadcast system) processes the catechism for a while, and again produces an acknowledgment and stops. However, there are additionally problems area we do not appetite the arrangement to anytime stop. Examples of such problems accommodate the dining philosophers botheration and added agnate alternate exclusion problems. In these problems, the broadcast arrangement is declared to continuously alike the use of aggregate assets so that no conflicts or deadlocks occur.

There are additionally axiological challenges that are different to broadcast computing. The aboriginal archetype is challenges that are accompanying to fault-tolerance. Examples of accompanying problems accommodate accord problems,33 Byzantine accountability tolerance,34 and self-stabilisation.35

A lot of analysis is additionally focused on compassionate the asynchronous attributes of broadcast systems:

Synchronizers can be acclimated to run ancillary algorithms in asynchronous systems.36

Logical clocks accommodate a causal happened-before acclimation of events.37

Clock synchronization algorithms accommodate globally constant concrete time stamps.38
