Jitter is defined as a variation in the delay of received packets. At the sending side, packets are sent in a continuous stream with the packets spaced evenly apart. D If the jitter is so large that it causes packets to be received out of the range of this buffer, the out-of-range packets are discarded and dropouts are heard in the audio.
Due to network congestion, improper queuing, or configuration errors, this steady stream can become lumpy, or the delay between each packet can vary instead of remaining constant.
Steps to Resolve:
- Purpose: Throughput essentially is your average network performance including during peak usage. We will do this through a ping test. We want to understand if your packet loss is being caused by network congestion due to overloaded network hardware. One way to evaluate this without Enterprise IT software is to run a ping test on your network to determine if you have high latency (measured in ms) due to network congestion.
- To do this we'll go to http://ping-test.net/ and select Auto-select server and accurate.
- Press Start PING TEST and let the test run. (Note: I recommend running this test after normal business hours.)
- From the closest region server, we want to look at the average, median, min. and max ping values in ms. Follow next steps based on your ping test results.
- 0-75ms average ping:
- standard expected range. Please continue to step 5 to troubleshoot.
- 76ms-150ms average ping
- acceptable range but may experience some packet loss. Please continue to step 5 to troubleshoot.
- 151-300ms average ping
- You will experience call quality issues and your networking hardware likely is the cause of your packet loss. We recommend continuing to the next step but you may want to consult your IT professional for network hardware suggestions
- 300ms+ average ping
- You may experience call drops and the packet loss messages you see likely stem from poor networking hardware. You should continue to step 5 but should improve your network hardware quality.
- 0-75ms average ping:
- Contact Your ISP mentioning that your Jitter and/or Latency is exceedingly high. They should provide some troubleshooting steps.
- Purchase adequate networking hardware to support your internet usage.
