editReading this article (with some previous knowledge of real time systems) I think the article should benefit from explaining
- why is the algorithm difficult to implement in hardware? What about software?
- what is meant by representing "deadlines in different ranges"?
- how can a deadline (which has the quantity of physical time) be rounded to bytes?
- what exactly is meant by insdustrial real-time systems? As opposed to what?
I myself is not capable of answering these questions. (That's why I read the article.)

There is a lot of missing informations : The necessary and sufficient conditions for instance, the maths behind, eventually also the proof of why EDF is optimal. Or references to those things. —Preceding unsigned comment added by 84.74.72.105 (talk) 17:21, 14 January 2008 (UTC)

Time can be rounded, because every system has its own time representation, so it is only a question of the granularity of the clock of the system. --Koempy (talk) 15:00, 11 February 2008 (UTC)
- A link to a paper on "schedulability test" was added plus a note on the hazard of "deadline interchange" when shared resources are used. There is an entry on a paper dealing with "deadline scheduling with reneging" when heavy traffic occurs. EDF is equivalent to Least-Time-to-Go. Thus an additional link was added.

Example
editThe example is too terse. What is meant by the "period" column in the table, for instance? zazpot (talk) 02:50, 22 April 2010 (UTC)
