Are there any reliable methods of calculating the current bitrate of an internet connection? -


I have experimented with a technique in which a web page is requested which you bit-rate based on bytes Use to calculate The time has passed, you can definitely average many data points, but is this like the exact bit-rate estimate?

Is there any professional or less harmful technique available? (Or is it just one of the magical mysteries of the Internet?)

How exactly is it dependent Does the speed information which you are interested in. You should be aware of many things:

  1. Speed ​​testing can be removed by caching
  2. CDN servers that catch a request
  3. DNS caching

requesting my suggestion to test a reasonable amount of unique sites [inside a qualified margin of error]

Many of them Test and take the average speed, this is the customer you can expect. The maximum is a projected maximum that the customer can receive. The minimum customer who can guarantee is 0 MBs.
