====== RTPClassifier Element Documentation ======

===== NAME =====

**RTPClassifier** -- Click element;
splits packets pertaining to an RTP flow from other BE traffic.

===== SYNOPSIS =====

RTPClassifier

**Ports**: 1 input, 2 outputs\\ 
**Processing**: Push\\ 
**Drivers**: linuxmodule\\ 
**Package**: unibo_qos\\ 

===== DESCRIPTION =====

Flows are classified as RTP if 6 following packets containing the
same SSRC field are received before TIMEOUT seconds.
If not, flow is not classified. Once a flow is classified, it can 
be cancelled if no more packets (with the same SSRC value) are 
received for TIMEOUTRTP seconds.
(TIMEOUT = 2 seconds, TIMEOUTRTP = 30 seconds).
RTP packets get out from output port 0, others from output port 1.
RTPClassifier[0]-> RTP traffic
RTPClassifier[1]-> non-RTP traffic *


===== EXAMPLES =====

elementclass class_RTP {
     $ssrc, $dscp |
     get::GetSSRC($ssrc);
     rtp::RTPClassifier;
     set::SetIPDSCP($dscp);
     input->get[0]->rtp;
     get[1]->[1]output;
     rtp[0]->set->[0]output;
     rtp[1]->[1]output;
     }
In the above example, RTPClassifier is used in combination with the [[GetSSRC]] and [[SetIPDSCP]] elements
to hook an RTP flow and mark its packets' DSCP field.
