I want to judge media protocol

I want to judge media protocol Flash video,Windows media over HTTP,Real media over HTTP and Quicktime over HTTP.

 

And I want to rate limit.

 

 

example...

 

 

if { protocol equals "Flash video" } {

 

rateclass rate_limit_flash

 

} elseif { protocol equals "Windows media over HTTP" } {

 

rateclass rate_limit_windows

 

} elseif { protocol equals "Real media over HTTP" } {

 

rateclass rate_limit_real

 

} elseif { protocol equals "Quicktime over HTTP" } {

 

rateclass rate_limit_quick

 

}

 

 

How can I do this?

 

Please...

    With Flash video (RTMP), you won't be able to use the HTTP events (since you can't use an HTTP profile on this traffic). I would collect and search the TCP payload for 'rtmp', then apply your rateclass.

     

     

    There is a lot of garbage that comes across before you ever see the RTMP connection string, so you'll want to make sure you have a big enough collection buffer (maybe 300?).
