What is VoIP Jitter: Exploring Definitions
What is VoIP Jitter: Exploring Definitions

Let’s start with a simple VoIP jitter definition!

VoIP jitter refers to the variation in the delay of received voice packets in a Voice over Internet Protocol (VoIP) communication system. In simpler terms, it represents the irregular timing or spacing between audio packets as they traverse the network from the sender to the receiver.

In a VoIP call, voice data is broken down into small packets and transmitted over the Internet. Jitter occurs when these packets experience varying levels of delay or arrive out of sequence at the destination. This variability in packet arrival times can lead to disruptions in the audio quality of the call, resulting in jitter-related issues such as choppy or distorted voice.

Jitter can be particularly problematic in real-time communication applications like VoIP, where maintaining a consistent and low-latency connection is crucial for a natural and fluid conversation.

Demystifying Jitter in VoIP: VoIP Jitter Causes
Demystifying Jitter in VoIP: VoIP Jitter Causes

Voice over Internet Protocol (VoIP) is a technology that allows voice communication and multimedia sessions over the Internet. Instead of traditional analog telephone lines, VoIP converts voice signals into digital data and transmits it over the Internet in the form of packets.

Jitter is the variation in the arrival time of voice packets during their journey across the Internet. These packets, containing audio data, are transmitted in real-time from the sender to the receiver. Jitter disrupts the regularity of packet arrival, leading to an inconsistent flow of voice data and, consequently, a degraded call quality.

Understanding the causes of VoIP jitter is crucial for effective troubleshooting and mitigation. Several factors contribute to the occurrence of jitter in VoIP communications:

1. Network Congestion Causing VoIP Jitter

How is VoIP Jitter Measured: Tracking the Packets
How is VoIP Jitter Measured: Tracking the Packets

VoIP jitter is typically measured using typical jitter measurements, which are expressed in milliseconds (ms). Jitter measurement involves assessing the variation in the delay of received voice packets over a specific period of time. The goal is to quantify how much the packet arrival times deviate from the expected or average delay.

1. Packet Timestamps:

VoIP devices, such as phones or softphones, attach timestamps to each voice packet at the time of transmission. These timestamps provide information about when the packet was sent.

2. Packet Arrival at the Destination:

When the voice packets reach their destination (e.g., another phone or VoIP gateway), the receiving device records the time of packet arrival.

3. Calculation of Interarrival Times:

The difference between the timestamp of a received packet and the timestamp of the previous packet is calculated. This difference represents the interarrival time.

4. Jitter Calculation:

Jitter is then calculated as the variance or average deviation of these interarrival times over a specific time interval.

Mathematically, jitter (J) is often expressed using the formula:

what is VoIP jitter

Jitter is presented in milliseconds (ms), representing the average or maximum deviation in arrival times.

5. Monitoring Tools:

Network performance monitoring tools, designed for VoIP systems, often provide real-time and historical jitter measurements. These tools may present jitter values on graphical interfaces, making it easier for administrators to monitor and identify potential issues.

6. Quality of Service (QoS) Metrics:

Jitter is one of the key metrics used in Quality of Service (QoS) assessments for VoIP. Network administrators use QoS parameters, particularly, QoS for VoIP and jitter, to ensure a satisfactory user experience.

Measuring jitter is crucial for maintaining VoIP call quality. By regularly monitoring jitter levels, network administrators can identify potential issues, troubleshoot problems, and implement optimizations to ensure a smooth and reliable VoIP communication experience.

what is VoIP jitter

We’ll dive into this a little more later on in the article but, when you’re measuring VoIP jitter, it’s important to understand how much jitter can affect VoIP performance. In VoIP communications, acceptable levels of jitter are generally defined by industry standards and best practices. However, what is considered "acceptable" can vary depending on the specific requirements of the application and the tolerance levels of the users.

As a general guideline:

1. Acceptable Jitter:

  • For most VoIP applications, an acceptable jitter level is typically around 30 milliseconds or lower. This ensures that the variation in packet arrival times is minimal, resulting in good call quality.
  • In situations where VoIP is used for casual conversations or non-critical communication, slightly higher jitter levels (up to 50 milliseconds) may still be acceptable without significantly affecting the user experience.

2. High Jitter:

  • High levels of jitter can start to degrade the quality of VoIP calls. Jitter above 50 milliseconds may lead to noticeable disruptions, including choppy or distorted audio.
  • In professional or business environments, where communication clarity is crucial, a jitter level exceeding 50 milliseconds is generally considered high and may require attention.

It's important to note that these are general guidelines, and the specific requirements for acceptable jitter can vary based on the nature of the VoIP application, the sensitivity of the users, and the overall network conditions.

Step 4. Monitor VoIP Quality using MOS Score
Step 4. Monitor VoIP Quality using MOS Score

Besides monitoring and identifying VoIP jitter itself, another way to proactively identify network issues affecting VoIP applications is to measure VoIP Quality. VoIP Quality refers to the clarity, reliability, and overall performance of voice calls made over a VoIP system.

Obkio’s Network Monitoring tool continuously monitors VoIP quality using a standardized rating system called MOS (Mean Opinion Score), which rates the quality of a voice call on a scale of 1 to 5. MOS scores are calculated based on subjective ratings from human listeners who rate the call quality based on factors such as clarity, background noise, and echo.

Since many people are not very familiar with the MOS Score and the interpretation of MOS in VoIP Quality, Obkio redesigned the MOS Score graph to create the VoIP Quality graph. Obkio’s MOS VoIP Quality graph categorizes, for every minute, the MOS Call Quality as

  • Best
  • High
  • Medium
  • Low
  • or Poor

  • Delay Compensation: The delay introduced by the jitter buffer allows for compensation in case of packet arrival variations. This helps maintain the proper pacing of audio playback, reducing the impact of jitter on call quality.
  • Buffer Size Adjustment: Jitter buffers can have adjustable sizes to accommodate different network conditions. A larger buffer may be suitable for networks with higher jitter, providing more room for compensation.
  • Dynamic Management: Some advanced VoIP systems implement dynamic jitter buffer management. This allows the buffer to adapt its size based on real-time network conditions, ensuring optimal performance.

what is VoIP jitter

Considerations for Jitter Buffers:

  1. Trade-off Between Delay and Quality: While jitter buffers enhance call quality by mitigating the impact of jitter, they introduce a slight delay in the transmission of audio. Striking the right balance between delay and quality is crucial.
  2. Configurability: VoIP systems often allow administrators to configure jitter buffer settings, including size and management strategies. Understanding the network environment helps in optimizing these configurations.
  3. Effectiveness in Variable Conditions: The effectiveness of jitter buffers may vary based on the severity and consistency of jitter. In highly variable network conditions, jitter buffers play a more critical role in maintaining call quality.

VoIP jitter buffers act as guardians of call quality, providing a mechanism to handle variations in packet arrival times. By intelligently managing delays and reordering packets, these buffers contribute significantly to a smoother and more reliable VoIP communication experience.
