content, but mainly residential). Because of the nature of the users on our network, we are considered Heavy Inbound since most traffic will be going from content providers to users on our network. It’s really as simple as that, we do no calculation to figure
out our traffic ratio and update according to some arbitrary ratio number, because none of that matters. That field in PeeringDB is used as additional information for someone who may look at the ASN and try to determine what to expect in general if connecting
to them.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">It kinda depends on the application that's being used. For example, videogaming has a ratio somewhere around 1:2.5 since you're only transmitting metadata about the players environment across the wire. The actual
video is typically rendered at the end user's side. So it's not very bandwidth heavy.<span class="apple-converted-space"> </span><br>
<br>
Compare that with a videostream (watching a movie or TV series) and you're pumping the rendered video across the wire, so there's a very different ratio. Your return path traffic would pretty much consist of control stuff only (like pushing the pause button).<br>
<br>
Some networks are dedicated to serving one type of content, whereas others might have a blend of different kinds of content. Same story for an access network geared to business users which want to use emails and such, vs residential end users looking for the
evening's entertainment.<br>
