Båndbredde test

Båndbredde test (meter) is a network service used to meter a speed of an internet connection by sending a one or more files of known size over a network to a distant computer (for eksempel, your own computer), measures the time required for the files to successfully download at the destination, and thereby obtains a theoretical figure for the data speed between two or more points, usually in kilobits per second (Kbps) or megabits per second (Mbps).

Bandwidth test results vary greatly, even from moment to moment, and occasionally produce absurd or improbable figures. Factors that affect test results include: Internet traffic (speed generally decreases as volume increases) Variable propagation delays (can artificially inflate or degrade the result) Noise on data lines (has a real detrimental effect) The size(s) of file(s) anvendes til test af antallet af filer, der bruges til test efterspørgslen belastning på test-serveren ved testen Måles og/eller tordenvejr aktivitet Båndbredde eller overførsel af data, er mængden af data der kan transporteres fra et sted til et andet i en given periode (normalt en anden).

Båndbredde er normalt udtrykkes i bits per sekund (bps); moderne netværk har typisk hastigheder målt i millioner af bits per sekund (megabit per sekund, eller Mbps) eller milliarder af bits per sekund (gigabits per sekund, eller Gbps). Bandwidth is not the only factor that affects network performance: There is also packet loss, latency and jitter, all of which degrade network throughput and make a link perform like one with lower bandwidth. A network path usually consists of a succession of links, each with its own bandwidth, so the end-to-end bandwidth is limited to the bandwidth of the lowest speed link (the bottleneck).

Effective bandwidth is the highest reliable transmission rate a path can provideis measured with a bandwidth test. Denne sats kan bestemmes ved flere gange at måle den tid, der kræves for en bestemt fil til at forlade sin oprindelse og kunne hente til sit bestemmelsessted.
