Whats typical? and theoretical?

uncongested network, within network. Node to node.

Typical and normal SLA is under 60 ms round trip. For theoretical you would need the distance and serialization delay (which is based on speed and frame size).

60ms is what I was going for (and argued with). Thanks for backing me up 🙂

So did folks think longer or shorter? You can't get around propogation and switching delay and that whole you're not really sending at the speed of light thing.

Shorter of course. It was a customer. Don't get me started.

Heh, well if they're on a T1 or less (or IMA) serialization delay is going to play a decent chunk. I always laugh at "well it shouldn't matter how far!" Yes it does, a lot.

Just tested.

California to Connecticut 90-95ms, California to New York 45ms

That's a huge difference considering they are next to each other.

No its much bigger pipes than T1. Regardless, I know I was right I just needed a little nod of assurance from another party.

sure they are next door to eachother, but whats the path? Same networks all along the way? 1 single congested router will add that 45ms. Not a good thing, but it can and will happen.

Yep. And since I have used Verizon DSL, Charter Cable, and monitoring a SBC (AT&T) network for my uncle's company, in my experience, Verizon is slowest and AT&T is fastest accross the country and overseas. Each individual's milage definitely vary.
