> Hmmmm. Someone told me once that real-time means on a > time scale such that no measurable time elapses between event > occurrences and their recognition. There are technically 2 different types of real-time. Hard real-time means that all processing required is always performed before the next buffer arrives. Soft (or statistical) real-time means that on the average processing finishes before the next buffer arrives, but additional memory will be needed to ensure that data is not lost. So there is no absolute cap on the time-scale for RT delays, it depends on the rate of the data being processed. <snip> > Admittedly, in a networking context, real time is being > measured over shorter and shorter time intervals. But the > Area being proposed is not really about networking, is it? I hope it is. As I mentioned in my first email on this subject. separation of the processing from the networking results in suboptimality of the combination.
