Configuring the jitter buffer
Jitter, packet loss, and packet disorder occurs during the transmission of voice packets over IP networks. By using a series of adaptive algorithms, the jitter buffer stores the received IP packets for a period of time and sends the packets in evenly spaced intervals. The jitter buffer reduces packet delay and jitter, and improves the communication quality.
To configure the jitter buffer:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter voice view. | voice-setup | N/A |
3. Enter voice dial program view. | dial-program | N/A |
4. Create a POTS voice entity and enter POTS voice entity view. | entity entity-number pots | N/A |
5. Set the operating mode of the jitter buffer to adaptive. | jitter-buffer mode adaptive | Optional. By default, the adaptive mode is disabled and the jitter buffer does not buffer any voice packet. |
6. Set the operating parameters for the jitter buffer that operates in the adaptive mode. | jitter-buffer delay { initial milliseconds | maximum milliseconds } | Optional. By default, the initial buffering time is 30 milliseconds and the maximum buffering time is 160 milliseconds. |
