| Q: | When playing an "Internet game" such as Unreal Tournament, there is a need for a low "ping"(lower the better) What exactly is a "ping" and how can I find out which ISP offers the lowest "ping"? | |||||||||||||||||
| A: |
Loosely speaking, the ping is similar to a sonar ping on a submarine. The Ping is sent out, it bounces off the other object, the reflection bounces back and the amount of time it takes for the round trip tells you how "far" away the other object is.
Because the internet is not just one big computer, your ping time will be different to every different computer on the Internet. While you may be "close" to a computer that is 1000 miles away - because you and the other computer are on the same backbone, the computer across the street might be at the other end of the Internet, because the route that messages take crosses through 4 backbones to get to the final destination.
If you are using a dialup connection, the first hop will take about 160 ms (1000 ths of a second) -
the path between your modem and the ISPs modem should be the slowest part of the entire trip. Everthing beyond the first hop should
be over very high speed connections and shouldn't add more than 10 or 20 ms per hop. If you spot a place where the times have a big
jump, you've identified the source of the slowness. The most important places in the traceroute are to
count the number of times the company name changes. If it changes 3 or 4 times before getting to the
destination, then the ISP has inadequate peering.
