![]() ![]() In the following Speed Test performed in, the total connection speed (100Mbps) provided by AT&T reduced to about 80%, which is not bad.Īccording to Speedtest from Ookla, the result of this test is an accurate measurement of HTTP throughput between the web server and the client. The concept of “Internet Connection Speed” is often used by marketers or sales representatives and is used by default to mean throughput, which is the actual rate of packet delivery over a specific medium. To get the 1000Mbps speed, the ISP will likely install powerful network devices, optical cabling, and open up a wider bandwidth connection. Internet Speed is a general term, that refers to the amount of data transferred per second through a specific connection.Ī good example is AT&T’s Internet Fiber connection offers. But in real life, you’ll be affected by other factors and will end up getting the throughput. When you buy an Internet connection at a certain speed, you are theoretically getting a specific bandwidth connection. Throughput is often confused with bandwidth and in worst cases with Internet Speed. In common practices, the actual throughput should be at least 50% (or more) of the total bandwidth. When adding up all these factors, the bandwidth turns into a throughput. The concept relates to perfect and theoretical conditions.īut in real life, it is affected by countless factors, such as: It is like the size of the pipe or the highway, two lanes, three lanes, 50 lanes, etc. How is Bandwidth different than Throughput?īandwidth is the Total Capacity of a system to send data to another over a single media. Throughput shows its results as an average and uses “data units per time” metrics such as bits per second “bps” or packets per second “pps.”Īlthough the concept of throughput is similar to bandwidth, they are not the same. When referring to communications, network throughput is the rate of message delivery over a single channel. In other words, it is the exact amount of data passing through the media from point A to point B in a determined amount of time. Throughput is the actual capacity of a system to send data to another, counting additional factors. ![]() Concerning all these factors, the highway’s throughput was 1000 cars per hour. There are tolls, rush hour, roads under maintenance, accidents, and many more factors that affect how a car moves from point A to point B.Ĭhina’s highway probably had the best bandwidth in the world but the poorest throughput at that time. In optimal conditions, cars would use all lanes and move at average speed. The highway’s bandwidth was at its full capacity (before the toll and the holiday) and was able to handle millions of cars per hour. So why does this story relates to throughput? Imagine that the highway is a network connection and each car is a bit of data. Do you think a 50-lane highway is the fastest? Apparently not… ![]() Thousands of drivers trapped for hours in an endless hair-pulling journey back home.įifty lanes merged into twenty lanes after a newly constructed toll, and it was also the end of an important National Holiday in China. It happened near a toll station in a 50-lane highway. On October 6, 2015, close to Beijing, China, thousands of cars were stuck in one of the biggest traffic jams in history. ![]()
