I have a radio station customer who is utilizing one of those streaming services to bring their broadcast station online. We've received a complaint of a half dozen or so 1-second drops in connectivity over the Internet to this streaming service in the six or so months they've been a customer. I consider that pretty amazing service delivery. However, the customer does not. I suspect this is a layer 8 issue, but what have your experiences been in these kinds of situations, and what technical remedies would be available? I don't know what sub-second failover systems exist, but I'm sure they're not cost-effective if they do.
If you've lost one second, 6 times in six months, that is like *six* nines for the year; already 10 times better than most commercial services (it's about 6.5 nines, actually: https://www.bmc.com/blogs/service-availability-calculation-metrics/ That's already, likely, *much* better than they're paying for. Pushing to seven nines will cost about ten times what they're paying now. This is what we used to call a "Sales problem", in my IT work; the problem is not that the service is bad, the problem is that the customer doesn't have reasonable expectation, because it's not been explained to them what service levels are, and how much it costs to add each "nine" at the end of that measure. I know this won't help, but I hope this helps. :-) Your problem is worse, because if your outage is only 1 second, you have to guarantee that any duplicate presented streams are in sync to no less than 9/10 of that, 100ms or less. Can you just turn the buffering up a second? Cheers, -- jra Cheers, -- jra -- Jay R.
