Hi guys,
I know that this could be considered a bit off the topic, I've just posted
this topic at VoIPSEC mailing list but I just thought this could be very
interesting for Asterisk community members so I'm posting it here too.
So the point is for traditional telephony we expect service availability of
99,999% and what about VoIP providers around the world what is currently
available?
I know that some operators are not owners of the infrastructure so this
becomes even harder to warranty the high level requirements that telephony
demands.
The best info and explanation I've found until now is: from bandwidth
at http://www.bandwidth.com/pdf/voip/bandwidth_voip_sla_062105.pdf
It would be interesting to discuss the recommend values needed and available
at SLA agreements:
Max Latency
Max Jitter
Max Packet Lost
Mean Time Between Failures
Mean Time To Repair
Mean Opinion Score at least 4 ?
Service Availability, this point as you probably are aware is very
important, what I just notice a few time a go is that the difference between
99,9% and 99,999% is big!
99,9% -> Max time for Outage during one month is 43,2 minutes ,
considering 30 days per month
99,999% -> Max time for Outage during one month is 0,432 minutes
If any of you around the world is aware of this values for VoIP SLAs I
would be thankful to exchange and discuss this info.
Thanks in advance.
Best regards,
Marco Mouta
