I'll take the opportunity to plug some old friends at the RIPE Test Traffic project. They are measuring and analysing unidirectional latencies and routing vectors using GPS as a precision timesource. Daniel Karrenberg shed some statistical light on their raw data at RIPE-38. http://www.ripe.net/test-traffic/ for more information. Joshua On Wed, 22 Aug 2001, Larry Diffey wrote:
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.
