The network god is about to speak<br /><br />shaping of packets is usually handled by some robust appliance, like a Juniper module. This also usually takes place at the router, a hundred thousand dollar type of router. <br /><br />In most cases when playing video games at home you would want to adjust your router to handle you gaming app. As stated Doom doesn&#039;t use much space packet wise but this wont prevent the packet from going through unless your ISP is gay. When a packet doesn&#039;t reach the minimal allowed size to get bagged and tagged it gets filled with fluff aka 0&#039;s. Then it is sent. Since home users aren&#039;t network technicians and they don&#039;t tend to understand the concept of syn, syn ack statements or in some case bandwidth and MB vs Mb, retail routers play this roll. Simply add your game box to the DMZ for full throughput of data, if your not comfortable with this you can port forward a range and let udp packets fly around in it for you game box.
