Non-Critical Applications

Non-Critical Applications
OK, but what about non-critical applications? The problem with considering the non-
critical definition of success is that if you have a network that can’t carry mission critical
traffic, then it may be on the ragged edge of being acceptable for non-mission critical
traffic – depending on how non-important the “non-critical” voice is. When operating
with payload near the available bandwidth, a slight increase in shared payload, or a slight
decrease in public bandwidth will easily increase the dropped packets from an occasional
syllable, to whole sentences. This could significantly inhibit the ability to receive even
mildly important voice traffic.
Using the Internet
Zetron never recommends putting mission critical voice over the internet (the worst
of all public networks) because once on the internet there is no way to ensure necessary
bandwidth, and there are no provisions in the internet infrastructure to prioritize voice
packets over other traffic. There may be special tunneling devices (or services such as
VPN) that improve it, but no device or service can absolutely guarantee loss-less delivery
over the internet. However, the internet may work just fine for non-critical voice,
especially casual monitor-only audio.
