    In-Bandwith and Out-Bandwith

    incoming bandwidth to a server: you upload files using FTP to a server, email received to the server, DNS queries, etc
    outgoing bandwidth froma a server: somebody download files from a server, somebody access your websites, email sent, etc.

    In-bandwidth is the data that is transferred to the server from another server/client and out-bandwidth is what is sent from your server to another server/client.

    Most servers used for hosting are sending a lot more bandwidth compared to what they receive because all visitors to the site are generating out-bandwidth (and some in-bandwidth but not much) and in-bandwidth is only generated when the webmasters upload files and so on to the server.

    Thank You

    Thanks all. The reason I'm asking is that I want to optimize the usage of these 2 type of bandwith.

    Managed just send me a link to my server bandwith usage: http://mrtg.managed.com/25b/65.75.143.254_fa0_19.html

    They projected by April 10th my server usage is about 1297GB which is about $648.49 in over usage fee. This is alot.

    By looking at the MRTG graph, I see too much In bandwith. Even though I don't allow people uploading and I don't do much uploading either. I also have out-going emails generate from the php script but not in-coming mails. Oh, and this server is hosting just a bulletin board where poeple do most the browsing. it's busy, around 400 online during day and 1400 during night. But that would make the out bandwith hight; So, how the in bandwith made up?

    Also, by looking at the MRTG graph, would anyone show me how to calculate the total bandwith in GB from billing date to billing date ? This would help me monitor the usage better.

    Thank you.

    incoming bandwidth is WAY too high for a forum, like 10 times over normal. I'd check your server with netstat or see detailed traffic logs since something is obviously not right here. I can't imagine VB config which would generate this many legitimate uploads...

    You should expect a decent amount of IN bandwidth (I'd say 10-15% of your OUT), but not that much... yikes.

    How much do they charge for overage?

    What's weird about yours webrats is your high IN traffic started rather suddenly, about a week ago. Until then, it seemed relatively normal.

    In both cases here, mine and webrats', the IN bandwith is way higher then Out and amusive.com said normal ?

    Hi webrats,
    are you mainly using this server for your http://forums.webrats.com/ or you host any other site?

    IN from the router's perspective is OUT from your server's.

    But the OUT from the router's perspective is IN from your server's, and really quite high unless you have a lot of people uploading things... For typical http traffic, I'd expect it to be 10-25% of your total traffic... as opposed to about 35-45% it seems like on yours.

    My point though is that your server's outgoing bandwidth (pages served, essentially) stayed relatively the same. It's connections and traffic going into your server that greatly increased... meaning more uploads, or something. Seems kind of odd.

    Thanks for the clearification amusive!

    I don't know who is the owner of this server and don't know how he does it. But looks like it very cost effective of using In bandwidth.

    If you are the owner, please let us know and help us to learn how to manage this too.

    That looks to be a "normal" ratio between IN/OUT

    First, install MRTG locally. It'd be interesting to see how the graphs compare (there's probably a howto on that here, somewhere).

    Second... I have no idea how you'd solve it. You'd need to find out what's causing it first, but I'm not entirely sure how to do that.

    Also, I'm just saying what I think is true based off my own experience. There may be some reason your forum uses so much server-bound traffic, but I really can't think of one.

    NO. NOT 500 in 500 out and NOT 1000 in 1000 out either. They count 1000GB total (in+out).
