|
|
>The purpose of this document is to suggest a way to manage outbound
|
|
traffic on an ADSL (or cable modem) connection to the Internet. The problem
|
|
is that many ADSL lines are limited in the neighborhood of 128kbps for upstream
|
|
data transfer. Aggravating this problem is the packet queue in the ADSL modem
|
|
which can take 2 to 3 seconds to empty when full. Together this means that when
|
|
the upstream bandwidth is fully saturated it can take up to 3 seconds for
|
|
any other packets to get out to the Internet. This can cripple interactive
|
|
applications such as telnet and multi-player games.</P
