Maximum Latency for ISPs?

fluor2 asks: "My ISP is providing me 8mbit ADSL, and my speed is in fact 8mbit (downstream). However, we all know that there is no relation between transfer rate and latency, eg, a high transfer rate and high latency will kill your FPS games. A packet that travels through the sky and up to a satellite is bound to give high latency. Using pathping, I discovered that my ISP provides me with a latency of 22ms before my sent packets are sent out of my ISP's backbone (6 hops). I have a friend that also tried the same, and he got only 10ms before he was out of his ISP's network. I know 22ms is decent, but I still think that it's far too high if one uses IP-phones and similar. What kind of latency can we accept for a normal 8mbit ADSL connection, and isn't it about time that we get more focus on this subject?"

"Normal" 8Mb?

I've got 512/128kb and consider it to be luxury. Perth, West Oz.

That's good..

I get 15ms to my ADSL modem, and I used to get 33ms. You are getting pretty good pings if it's still in your ISP, except about 40ms in your ISP.

I don't see whats wrong with what you are getting, maybe you are whining just a little bit too much about what you are getting.

Heck, I'd like 8mbps down on my ADSL. I'm stuck with 1.53mbps/640kbps.

Oh well. There is nothing wrong with what you get..

Latency to where?

Latency-to-edge-of-network has got to be the most broken benchmark I've ever seen. If your network passes its traffic off to a different network within the same city, while my network takes it halfway around the world and passes it directly to the destination machine's network, my packets are going to be staying within my network for a long time... but they'll probably reach their destination sooner than yours.

If you're going to measure how long it takes for your packets to get somewhere, make sure you also measure where your packets are getting to.
