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. 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.Ĭoncerning all these factors, the highway’s throughput was 1000 cars per hour. In optimal conditions, cars would use all lanes and move at average speed.īut in real life highways are busy. 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. Imagine that the highway is a network connection and each car is a bit of data. So why does this story relates to throughput? 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.ĭo you think a 50-lane highway is the fastest? Apparently not… 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.
