Re: Long haul latency calculation?

I was wondering if there is a benchmark for long-haul circuit latency... For example if I had a T1 circuit with 2900 miles between the two end-points (and assuming the provider is best case scenario) can I do something like (miles*latencyfactor) = 5 ms for 2900 miles?

Speed of light is apprxoximately 2.998e+8 m/s (or 299,800,000 m/s), which is approximately 186,287 miles/sec. 2900 mi / 186,287 mi/s = 0.01557s = 15.57ms. This is the absolute minimum latency you can possibly get over that distance. Switching performance and congestion will make your actual latency somewhat larger. -- David
