Kvalita linky 3

Mailen (12.9.2008 13:53:06)

Ahoj, může mi někdo v oboru znalý říci jestli mám dobrou linku nebo ne? Chtěl bych na ní provozovat 16MBbit/s.

16M by mělo jet v pohodě.

Anonym (12.9.2008 14:33:18)

16 Mbit/s nepojede,už teď má linka attainable rate downstream: 17788 kbps a ES: 412 při line rate 10240/639 kbps,takže na stabilní rychlost bych to viděl tak max. 12 Mbit/s.

bandita (12.9.2008 15:59:12)

Co tohle? Ted 6Mbit a jede neco pres 5Mbit. zatim spokojenost Downstream Upstream SNR Margin (dB): 11.4 25.8 Attenuation (dB): 37.5 30.0 Output Power (dBm): 18.5 13.8

Anonym (12.9.2008 20:48:48)

chybí tam attainable rate,bez tohohle údaje je to věštění z křišťálový koule.Obecně lze říct,že maximum na kterým linka poběží stabilně je někde kolem 2/3 attainable rate a SNR cca 12 dB a více.

bandita (12.9.2008 21:12:21)

Michal (21.9.2008 13:22:37)

Promiňte za blbý dotaz, ale kde seženu tyto údaje, podle kterých tady pár lidí dokáže poznat kvalitu linky? jde mi o to, že bych si chtěl pořídit 8Mbit i spevnou linkou, kterou zatím nemám. Tak jsem použil sousedovo tel. číslo pro ověření dotupnosti a vyhodilo mi to tohle: V síti O2 maximálně 6144/384 kbit/s. Jsem něco přes 2km od ústředny. Těch 6Mbit co mi to naměřilo, ale není rychlost, kterou mi potom vyhodí měřák rychlosti internetu, že? Dík moc za každou radu.

TTx (21.9.2008 17:32:49)

Přesně tuhle lajnu mám 6144/384 a tu máš výsledek na speedtestu ať máš představu kolik to jede realně. http://rychlost.cz/rh/20083788522-896d0ab429.html

TTx (21.9.2008 17:38:13)

Jako up je občas i kolem 630KB/s ale to je detail řešit nějaký drobný... http://i38.tinypic.com/23qx64k.jpg

On nějaký tarif 12M je? Není...

Nargon (12.9.2008 18:41:11)

Neni, ale kdyz si objedna sluzbu "až" 16Mbit, tak mu to pojede tech 12.

Roman_HK (12.9.2008 20:48:06)

12M je víc, než 8M => linka je "vhodná" na 16M.

Dobrý den. Chtěl bych se zeptat, jak tyto údaje zjišťujete? Přes 10.0.0.138? Když toto zadám do prohlížeče, nic se nenačítá. Děkuji

Sitta Mirek (21.9.2008 21:06:33)

Tohle měření rychlosti a dostupnosti na Lupa.cz mi nepříjde moc reálné. Já mám ADSL 2Mb a při ověření na moje tel.číslo tu hlásí dostupnou rychlost 2mb. A když tam dám tel.číslo tchýně která bydlí v patře pode mnou hlásí to dostupnost až 9Mb. Tak jsem blázen nebo co?
