Najboljši routi na optiki

Najboljši routi na optiki

DejaVu ::

Kateri operater optičnih storitev v SLO ima najboljše route po Evropi? Imam možnost naročila SiOL (že imam), T-2 in Amis. Izbral bi tistega, ki ima najboljše route, torej posledično najnižje povprečne latence do držav kot so Nemčija, Nizozemska, VB, itd... To mi je bolj pomembno kot pa tistih nekaj mb/s hitrosti gor/dol.

Btw, vem da je pred leti imel SiOL na dinamičnih IPjih, dodeljenih iz ranga 109.x.x.x za nekje 10ms boljše routinge do UK kot na statičnih IPjih. Tako sem na dinamičnem IPju ranga 109. imel zgolj dobrih 30ms pinga do serverjev v UK, kar je res zavidljivo dober rezultat.

Glede na to:

http://www.cogentco.com/en/network/look...

ima T-2 za skoraj 10ms boljše pinge...

še amis poseka siol za cca 5ms...

Zgodovina sprememb…

DejaVu ::

Ok preverjeno. Zdaj imam optiko Siol in T-2. Do UK ima T-2 skoraj 10ms nižje latence. Če koga zanima še kakšna primerjava, naj vpraša, ker bom kmalu Siol odjavil.

Druga zanimivost je ta, da mi speedtest.net pravi, da imam kar 44mbps uploada (linija 20/20 T-2). NDT arnes pove da imam rahlo nad 20mbps uploada. Rad bi še preveril na kakšnem hitrem FTP strežniku kaj je dejansko res...

techfreak :) ::

speedtest.net občasno laže, tako da se ne zanašaj na njega. Arnesov je načeloma veliko bolj natančen, za kakšen dejanski test pa lahko preneseš npr. Ubuntu ISO ali kaj podobnega preko torrenta in boš videl kakšna je hitrost.

Drugače pa ja, tudi hardware (ta Milan optični pretvornik) od T-2 zgleda bistveno bolj profesionalno kot tisto plastično sranje od Siola. Do vstopne točke pri T-2 imam < 1ms pinga, kar je res fenomenalno. Poleg tega imam kar tri externe IPje - enga statičnega in dva dinamična. Siol tega niti približno ne ponuja.

Mislim, da bom kar odjavil Siol in obdržal T-2 (mogoče kdaj v prihodnje posegel po 100/100, glede na to, da stane le 51 EUR na mesec).
