QOS inbound limit question

    I decided to have a play around with QOS a few days ago. I did some speedtests and set the limits to 98% of my speedtest results to allow for a little fluctuation. (reasonable?)

    Today i was using utorrent and the router lost the connection, then immediately reconnected. When the torrents reached full speed they were about 50% higher than before and i realized that my provider must have increased my ADSL speeds unannounced... I logged into the modem and sure enough the link was now 3072/1024 instead of 2048/1024.

    But since I had limited download speeds from the values i got when testing the 2048 link, how did the router allow the torrents to reach the higher speeds beyond the limit i set? Or is the download limit ignored when all the class limit restrictions are set to 'none'?

    Well, from what I read here, half of the majority perfer to have web access when the line gets fully saturated, I guess it all depends on how the ISP handles there bandwidth I use adsl..

    Coming from a cable modem ISP background, that'd never work. I set mine at 90%.

    If you set the outgoing limit to almost 100% you leave no room left in the transmit buffer for QOS to work. That is why the wiki tells you that it MUST be set to a lower figure, as bribab007 points out. Usually 85-90% of the MINIMUM speed that you EVER get after measuring at different times of the day. For your ADSL, if you have 1024 up (I'm jealous) that might be typically 700k. ADSL speeds are rarely anywhere near the stated speed.

    OK, i'll cut it back to 90%. i hadn't seen that in the wiki.

    What i still don't understand is why was i able to get download speeds 50% higher than the limit i had set. Doesn't that mean the limiting is not working?

    Vezad, sorry not to have answered your question. Yes, this is the difference between 100% and NONE in the selection box. NONE allows that class to ignore the overall limit. If you want to know more about QOS, check out this thread: http://www.linksysinfo.org/forums/showthread.php?t=60304

    Sorry i missed that bit. You've put a considerable amount of effort into that and I thank you for your contribution to the tomato community. Well done, though to be honest i'm not all the way through it yet.

    Let me read up a bit more before i ask more questions that you've already answered. :)

    I yelled "ya para! ao ya para!" downstairs but the gf is ignoring me.

    Who's your provider btw? Maxnet bumped up the premier accounts last night which is what actually started this thread. I have mixed feelings about these BW increases, it seems nice but we still have insufficient international connections and i'm not too interested in domestic sites. At least my vpn and rdp stuff around town is a little snappier...

    I am in Thailand, and use TRUE internet who are doing a pretty decent job. We have 5 Mbps lines with 512k up at the moment, but 8Mbps is now being promoted by ISP's. Most of the servers people use here are actually located overseas, so international bandwidth is very important to us. At the moment, Thailand is lagging behind, and things are pretty (some say dreadfully) slow.

    I knew you were in thailand, or were before, that's why i was curious who you were using and mentioned the international BW issues. I was on a True cable internet connection last year but changed to maxnet (tt&t) adsl this year when i moved. I'm in Chiang Mai.

    The providers seem to be in a battle of who can offer the most for the lowest price without updating the infrastructure and international links to support it and it's becoming a bit of a joke. Maxnet is offering 4096/512 connections for 590 baht but warn users not to sign up if they use many international sites. even then, it was still basically fraud because the 4mb connection had identical speeds to the 3mb connections (around 305 KBps) tops, even when pushed to the limits with download managers. only the actual adsl link in the modem indicated a 4mb link.

    The premier connection works much better, and the uplink is 1024. I'm still longing for my connection speeds from the US but it's better than before.

    i think i've just hijacked my own thread....

    Ah CM ! I see.

    A con - well, that's nothing new. I can't think of anything in Thailand that isn't a con, maybe if I put my mind to it I could come up with something. I lived in Hang Dong, CM a few years ago. Nice place, I had a nice house. Not like Bangkok hovels. Come to think of it, the owner also stole my deposit.

    TRU is not so bad, considering. They have lot of their own lines. Anyone that relies on TOT/CAT is wasting their time. Many overseas web pages here open in 2.5-3 seconds. Linksysinfo takes 3 seconds. Try also http://touregypt.net which I use for a test.
