[BC] Starguides: Going Away

[Dana Puopolo]

QOS routers are available for 49 bucks these days. Using an ISP like Directway
(satellite) universally would insure that the delay is constant between all
stations. Staying within one company's infrastructure also eliminates the use
of peering points, which is usually where packets get lost. 

There are ways of making IP audio transfer work well and reliably. You simply
have to know the limitations and follow the rules.

"could" is the key word in there, depending on network conditions, various
backbones and routing paths, there is really no way to precisely, 100% of the
time, sync all client sites as you can when you have a known constant like a
dedicated transponder on a satellite with X amount of delay end to end.

The other issue would be reliability, IP networks for remotes - sure.  Using
public, non QOS enabled networks, for an STL or for live long form program
delivery, you'd have to be nuts or just like playing with fire.

Using UDP, the delay could be under a second. Besides, most radio networks
run
a minimum 7 second delay (and I know some that run as much as a minute
delay),
and compensate by setting their network clocks fast.
