SD-WAN is a relatively new technology that is being adopted by many organizations in order to improve their WAN performance. SD-WAN offers a number of advantages over traditional WAN solutions, including improved performance, lower costs and easier deployment. One of the main benefits of SD-WAN is its ability to improve video performance. Video is one of the most demanding applications when it comes to network bandwidth. Network bandwidth is often the bottleneck for video performance. SD-WAN can help to alleviate this bottleneck by dynamically routing traffic over the best-performing path based on real-time conditions. This can result in a significant improvement in video quality and performance.
There are a number of factors that can impact video quality, including the encoding of the video, the bitrate of the video, and the resolution of the video. The quality of the video is impacted by the codec that is used to encode it. In general, newer codecs are more efficient and result in better video quality. While bitrate of the video impacts the video quality. A higher bitrate result in better video quality, however, it uses more bandwidth. In addition, the resolution of the video also impacts the video quality. A higher resolution results in better video quality but requires more bandwidth. In addition to that, Network conditions also have a significant impact on the video quality. If the network is congested, the video may be choppy or pixelated.
A single high-definition video call can easily consume as much as 4 Mbps of bandwidth. While considering most organizations have multiple video calls taking place at any given time, it’s easy to see how video can quickly tax a traditional WAN. However, with SD-WAN in place, an organization can support a large number of high-definition video calls without compromising its performance. SD-WAN can also help to reduce the number of dropped video calls. When traditional WAN solutions are overloaded, video calls are often the first to be dropped. This is because video requires a continuous stream of data to be transmitted properly. If the data stream is interrupted, the call will be dropped. SD-WAN can help to ensure that video calls are not dropped by dynamically routing traffic around problems on the network. This can greatly improve the reliability of video calls and make them more likely to succeed. SD-WAN can help to improve video quality if the network is congested by dynamically routing traffic over the best-performing path based on real-time conditions. This can result in a significant improvement in video quality and performance. Thus, SD-WAN offers a number of benefits that can help improve video performance, including:
1. Quality of Service (QoS)
SD-WAN can automatically prioritize video traffic, ensuring that it always has the bandwidth it needs. Moreover, by dedicating a certain amount of bandwidth to video, organizations can avoid the “buffer bloat” that can often occur when video shares a network with other traffic types.
2. WAN Optimization
Through SD-WAN, one can take advantage of WAN optimization features, such as compression and caching, which can further improve video performance. Video performance can be improved by optimizing the WAN through SD-WAN by compressing traffic, reducing latency, and improving throughput. Moreover, WAN optimization can be used to improve video quality by reducing jitter and packet loss. In addition, WAN optimization can also be used to improve video performance by caching video content. Moreover, by optimizing video traffic, organizations can free up bandwidth for other applications.
3. Traffic Shaping
SD-WAN can also help to ensure that video traffic is not impacted by other traffic types on the network. This can be accomplished by allocating a certain amount of bandwidth to video or by shaping traffic so that video always has priority. Moreover, video performance through SD-WAN can be further improved by using Quality of Service (QoS) to prioritize video traffic.
4. Improved Reliability and Performance
By dynamically routing traffic around problems on the network, SD-WAN can help to ensure that video calls are not dropped. This can greatly improve the reliability of video by making it more likely to succeed. By dynamically routing traffic over the best-performing path, SD-WAN can significantly improve video quality and performance.
5. Network Monitoring
SD-WAN can also provide visibility into video traffic, allowing the organizations to see which users are consuming the most bandwidth and identify any potential problems. This information can be used to fine-tune the video quality and ensure that users are getting the best possible experience.
6. Reduced Latency
One of the biggest benefits of SD-WAN is its ability to reduce latency. Reduced latency can help improve video quality by reducing the amount of time it takes for packets to travel from one location to another. Moreover, it can also help improve video performance by reducing the amount of time it takes for packets to be buffered.
7. Increased Bandwidth
SD-WAN can also help to improve video performance by increasing the amount of bandwidth available to video traffic. This can be done by bonding multiple WAN links together or by using a higher-speed WAN link. Moreover, by using SD-WAN, organizations can make more efficient use of their existing bandwidth by dynamically routing traffic around problems on the network.
8. Scalability
As video conferencing needs to grow, SD-WAN can be easily scaled to meet this demand. This can be done through SD-WAN by adding more WAN links or by upgrading to a higher-speed WAN link. In addition, SD-WAN can be used to connect multiple sites together, allowing organizations to easily expand their video conferencing infrastructure. Moreover, SD-WAN can be scaled to support more users by adding more SD-WAN devices to the network.
Conclusion
Hence, through SD-WAN, organizations and enterprises can improve video quality and performance by dynamically routing traffic, compressing traffic, and reducing latency, increasing bandwidth, and improving reliability. All of these factors can help to ensure that users have a better experience when using video applications. Moreover, SD-WAN can be easily scaled to support more users and more video traffic, making it an ideal solution for video conferencing.
