Testing the New Queue

The easiest way to test your new setup is to saturate the upstream with

low-priority traffic. This depends how you have your priorities set up. For

the sake of example, let's say you've placed telnet traffic and ping traffic

at a higher priority (lower fwmark) than other high ports (that are used for

FTP transfers, etc). If you initiate an FTP upload to saturate upstream

bandwidth, you should only notice your ping times to the gateway (on the

other side of the DSL line) increasing by a small amount compared to what it

would increase to with no priority queuing. Ping times under 100ms are

typical depending on how you've got things set up. Ping times greater than

one or two seconds probably mean that things aren't working right.

OK It Works!! Now What?

Now that you've successfully started to manage your bandwidth, you should

start thinking of ways to use it. After all, you're probably paying for it!
