Carrier Class = 5?
What makes a system “Carrier Class” (as in Telecoms Carrier)?? The answer is subjective of course but a few idle ideas popped into my head that I thought worth wasting a few lines for.
- 5 Nines Reliability, i.e. 99.999% uptime or 8.76 hours/year downtime (although hardware targetted at carriers usually quotes 6 Nines),
- 10^5 transactions/second on server infrastructure costing less than 10^5 dollars,
- 10^5 user capacity,
- 10 x 5 simultaneous calls per second,
