Fwd: SLA packet loss base

[정치영 <lionair () samsung com>]

Some people replied me about my questions. thanks for reply.
However, what I want to know ultimately is something like technical proof or standard or experimentation information
they can logically support SLA values in provider's IP network.  
For example, regarding packet loss, I found information it is based on voip service tolerance (al least below 1% packet 
loss).
but some provider announce they can guarantee 0.3% packet loss.  Where does 0.3% come from ?
Can anyone give me an answer about this question ?  In fact I am going to make some guideline of network quality of my 
network.

Best regards,
Chiyoung

Title  : SLA packet loss base

Hi all,

I wonder where we can find the base of packet loss rate of Global famous provider.
For example, the packet loss value of Sprint and NTT-Verio is same 0.3 % at their SLA.
