Description

Use the rtpq command to configure to apply Realtime Transport Protocol (RTP)

 

Priority Queuing.

 

Use the undo rtpq command to remove the application.

 

The application of a FR class configured with RTPQ to a PVC results in the creation

 

of a strict priority queue on the PVC. Packets in the port range specified by RTPQ

 

of the destination UDP port will enter RTPQ. When congestion occurs in the virtual

 

circuit, the packets in the queue will be absolutely sent with preference without

 

exceeding the configured bandwidth. When congestion does not occur in the

 

virtual circuit, the RTP packets in the specified port range can occupy the available

 

bandwidth on the virtual circuit. Generally, the UDP port range used by VoIP can

 

be configured as from 16384 to 32767.

Examples

# Configure RTP priority queue on the FR class named test1 with a bandwidth of

 

20 kbps.

[Sysname] fr class test1

Parameters

becn: Adjusts the packets with the BECN flag.

 

percentage: Adjustment percentage, ranging from 1 to 30 percent. The default

 

value is 25 percent.

 

interface-congestion: Traffic shaping according to the number of the packets in

 

the outbound queue.

 

number: Number of packets in the queue, ranging from 1 to 40.

Description

Use the traffic-shaping adaptation command to enable the adaptive traffic

shaping function of FR.

Use the undo traffic-shaping adaptation command to disable this function.

By default, traffic-shaping adaptation is enabled, and the ratio of each adaptation is set to 25.
