Software-defined wide area networks (SDWAN) have rapidly gained popularity in recent years as organizations look for faster and more cost-effective ways to connect their branch offices and remote workers. One of the key factors in SDWAN performance is the throughput and jitter of the network. In this article, we will explore the fundamental concepts of throughput and jitter in SDWAN and their impact on user experience. We will also discuss best practices for measuring, monitoring, and optimizing throughput and minimizing jitter in SDWAN networks.

Understanding the Basics of Throughput and Jitter in SDWAN

Throughput is the amount of data that can be transmitted over a network in a given time frame. It is typically measured in bits per second (bps) and is a critical factor in determining the speed and efficiency of an SDWAN network. Jitter is the variation in packet arrival time at the receiving end of the network. It is measured in milliseconds and is caused by delays in network traffic that can affect the quality of voice and video transmissions, leading to disruptive user experiences.

It is important to note that while high throughput is desirable, it can also lead to increased jitter. This is because a network with high throughput may become congested, causing packets to be delayed and arrive at the receiving end at different times. To mitigate this, SDWAN solutions often use Quality of Service (QoS) techniques to prioritize certain types of traffic, such as voice and video, over others. By doing so, SDWAN can ensure that critical applications receive the necessary bandwidth and minimize the impact of jitter on user experience.

The Role of Throughput and Jitter in SDWAN Performance

Throughput and jitter have a direct impact on the performance of SDWAN networks. Low throughput can cause slow application response times, sluggish data transfer, and poor user experience. High jitter can cause problems such as choppy audio and video, lost packets, and out-of-sync transmissions. Therefore, it is crucial to monitor and optimize both throughput and jitter in SDWAN networks to ensure high performance.

One way to optimize throughput and jitter in SDWAN networks is to use Quality of Service (QoS) policies. QoS policies prioritize network traffic based on its importance, ensuring that critical applications receive the necessary bandwidth and low latency. This can help to reduce jitter and improve throughput, resulting in better overall network performance. Additionally, SDWAN solutions often include built-in monitoring and analytics tools that can help identify and troubleshoot issues related to throughput and jitter in real-time.

How to Measure Throughput and Jitter in SDWAN Networks

Measuring throughput and jitter in SDWAN networks can be challenging due to the complexity of network architectures and traffic patterns. The most common tools used to measure throughput and jitter in SDWAN networks include network performance monitoring (NPM) and application performance monitoring (APM) solutions. These tools provide administrators with real-time visibility into network health and performance and help identify problem areas that require attention.

When measuring throughput in SDWAN networks, it is important to consider the impact of network congestion and packet loss. These factors can significantly affect the accuracy of throughput measurements and may require additional testing to obtain accurate results. Additionally, it is important to ensure that the testing methodology used is consistent across all network devices and locations to ensure accurate and reliable results.

Jitter, on the other hand, is a measure of the variation in packet delay and can be caused by a variety of factors, including network congestion, packet loss, and network latency. To accurately measure jitter in SDWAN networks, it is important to use specialized tools that can capture and analyze packet delay and variation. These tools can provide administrators with valuable insights into network performance and help identify areas for improvement.

The Impact of Throughput and Jitter on User Experience in SDWAN

The user experience is a critical factor in SDWAN deployment. Low throughput and high jitter can lead to disruptions in voice and video transmissions, reducing user productivity and engagement. These disruptions can impact the overall efficiency of the organization and can cause frustration among employees. Therefore, it is essential to prioritize user experience when optimizing throughput and minimizing jitter in SDWAN networks.

One way to improve user experience in SDWAN is to implement Quality of Service (QoS) policies. QoS policies prioritize certain types of traffic, such as voice and video, over other types of traffic, such as email and web browsing. This ensures that critical applications receive the necessary bandwidth and are not impacted by other less important traffic. By implementing QoS policies, organizations can improve the user experience and ensure that their SDWAN networks are optimized for their specific needs.

Best Practices for Optimizing Throughput and Minimizing Jitter in SDWAN

There are several best practices that organizations can follow to optimize throughput and minimize jitter in SDWAN networks. Proper network design, efficient routing, and effective load balancing are some of the critical steps that administrators can take to improve overall network performance. Additionally, using Quality of Service (QoS) policies and implementing end-to-end encryption can help ensure efficient usage of network resources and protect data privacy.

Another important best practice for optimizing throughput and minimizing jitter in SDWAN is to regularly monitor network performance and identify any potential bottlenecks or issues. This can be done through the use of network monitoring tools and analytics, which can provide valuable insights into network traffic patterns and performance metrics.

Finally, it is important to ensure that all network devices and software are kept up-to-date with the latest security patches and updates. This can help prevent vulnerabilities and ensure that the network is protected against potential security threats and attacks.
