That doesn't answer my question (I know the abbreviation RTT). Therefore I'm trying again:

I'm just wondering what the RTT *exactly* means. Where are the exact measuring points located?

=> How are the RTT values exactly calculated? Which values are actually used for?

=> What about the processing time between the inbound leg and the outbound leg (transcoding, ...)?


Thanks
