Čemu služi nPerf, tko smo mi?

Ciljevi nPerfa
Cilj nPerfa je pomoći vam pri mjerenju kvalitete vaše Internet mreže

nPerf je osnovan u Lyonu, u Francuskoj ,zahvaljujući timu strastvenih stručnjaka telekomunikacija koji svakodnevno rade kako bi vam pružili kompletnu, pouzdanu, ergonomsku i učinkovitu podršku.

Ključni brojevi
Što je nPerf ? nPerf predstavlja više milijuna testova brzine i 1 milijardu mjerenja godišnje za kartografiju mobilne mreže. Mreža servera nPerfa se sastoji od 350 i više servera diljem svijeta sa ukupnom širinom pojasa i do 1 Tb/s.

Kako funkcioniraju nPerf testovi?

Mjerenje brzine
Mjerenje brzine interneta se odnosi na skidanju podataka sa više istovremeno povezanih mreža kako bi opteretili vezu nekoliko sekundi te dobili što preciznije podatke o mreži. Najveća vrijednost je u prosjeku 30% uzoraka koji su postigli najveću vrijednost ( 50% za rastuću stopu). Srednja vrijednost brzine se izračuna tako da se 5% uzroka najmanje i najveće veličine oduzmu.

Mjerenje latencije
Test latencije služi za mjerenje vremena koje potrebno kako bi određeni paket podataka došao do servera i vratio se na početni terminal. Izvodi se deset puta. Na kraju vidimo rezultat minimalne, srednje i jitter vrijednosti ( maksimalna varijacija vrijednosti).

TCP/HTTP načini
nPerf prvo izvodi TCP test, to je najučinkovitiji način jer direktno uspostavlja sockete bez prolaska kroz pretraživač. Kako bi koristili TCP način, morate biti u mogućnosti pristupita daljinskim uslugama s portovima 8080 i 8081. Ukoliko TCP način nije moguć (port 8080 i 8081 blokirani), test će se izvršiti u HTTPu. U tom slučaju soketi prolaze kroz pretraživač. Učinkovito za brzine do 100 Mb/s, no iznad toga ovaj način rada doseže svoj vrhunac.

Kako podržati projekt nPerfa?

Opskrbiti bazu zajedničkih podataka

Osobni podaci

Koje to informacije nPerf točno prikuplja?

nPerf aplikacija prikuplja jedino lokalizirane statističke podatke . Ti podaci nisu osobni. Oni nam pomažu pri kvalificiranju mreža raznih operatera. Prikupljeni podaci postaju vlasništvo nPerfa. Prikupljeni podaci su sljedeći : lokalizacija, informacije o mreži, tip i model terminala, verzija sistema, mjerenja izvršena tijekom realizacije testova.

Što radimo s podacima ?

Prikupljeni podaci služe za razna objavljivanja. One su generalno izložene na našoj Internet stranici pod rubrikom statistike. Ukoliko bi se neki od podataka koristili u komercijalne svrhe, oni će biti u potpunosti anonimni ( IP adresa maskirana ).

Kako kupiti nPerf bruto podatke ?

Vrlo jednostavno !
Želite detaljnije analizirati prikupljene podatke ? Mi vam možemo dostaviti bruto podatke, anonimne i za određeno geografsko područje.
