Re: Measuring PoP to PoP latency--tools to use?
I will try not to violate my NDA here but there is a company that is nearly finished beta testing a service (hardware based) that is designed to measure latency, delay, jitter and packet loss. The initial product is meant specifically for the core but there is an edge product in development as well. I can't tell you anything more without getting myself into trouble.
