Benefits of Using SD-WAN for Better VoIP Performance

Businesses are always looking for cutting-edge solutions that can take their voice communication systems to the next level in the digital communications landscape. VoIP (Voice over Internet Protocol is an important element for many businesses, allowing them to make free calls around the world using an internet connection. Within such technology, voice communication is now included. However, it has obvious downsides and challenges in VoIP performance due to the density of network end-user software. This is where Software-Defined Wide Area Network (SD-WAN) technology comes in, as it provides a better way to improve VoIP performance. In this blog, we will explore how SD-WAN solves these problems, delve into some technical details, provide successful use cases, and recommend bringing SD-WAN on board with P J Networks pipelines to improve your communications.

An Insight into VoIP Challenges: Latency and Jitter

Voice over Internet Protocol converts voice signals into digital data packets that can travel on the internet. Although this technology provides a large number of benefits, it is extremely dependent on network parameters. Latency and jitter can often be behind poor VoIP call quality:

• Latency: This is the time between when a voice packet is sent and when it is received. Conversations overlap when there are noticeable delays (high latency).
• Jitter: This is where the voice packets are received at the other end at uneven times. They can make your audio sound choppy and impair comprehension of the conversation.

These two most common challenges are often the result of network congestion, packet loss, or misrouting, which all get amplified over traditional WAN architectures.

How SD-WAN Improves VoIP Performance

SD-WAN leverages software-defined networking to replace traditional WAN links with an application-aware network for dynamic and flexible connectivity. SD-WAN improves VoIP performance by reducing latency and jitter through the following methods:

1. Optimized Traffic Routing: The use of intelligent path control in SD-WAN ensures that traffic takes the route creating the best performance. SD-WAN can use network performance metrics, like latency and packet loss which it continuously collects, to automatically pick the best path for VoIP traffic. This reduces waiting time, making the communication smoother.
2. Voice over IP (VoIP) Traffic Prioritization: SD-WAN can give VoIP traffic higher priority than other data types using application-aware routing capabilities. This allows a user communicating via a smartphone on a 4G network to have voice traffic prioritized over data.
3. Bandwidth Aggregation: With multiple internet connections, SD-WAN helps in utilizing them all. These connections are concatenated by SD-WAN, ensuring sufficient bandwidth for VoIP apps, thus reducing the likelihood of latency and jitter.
4. Troubleshooting: Through troubleshooting approaches like Forward Error Correction (FEC), lost packets can be reconstructed by SD-WAN, safeguarding the integrity and improving the quality of VoIP voice streams.
5. Latency and Jitter Management: SD-WAN systems use powerful algorithms to identify and fix latency and jitter issues proactively, delivering seamless VoIP call quality under any network circumstances.

Technical Insights – SD-WAN

Unlike other WAN solutions, SD-WAN offers the ability to unify different transport technologies such as MPLS, LTE, and Broadband internet into one holistic network. Here is a detailed view of its technical properties:

• Centralized Control: SD-WAN establishes centralized control that allows businesses to develop policies and maintain security measures, aiding network management in data integrity and compliance.
• Real-time Visibility and Analytics: SD-WAN tracks the network constantly and displays analytics, enabling businesses to make informed decisions quickly.
• Zero-Touch Deployment: SD-WAN provides zero-touch provisioning, speeding up deployment and allowing it to be easily scalable, a significant benefit for large companies with various locations.

Enterprise Success Stories Utilizing SD-WAN

Many companies have leveraged SD-WAN to revolutionize their communication ecosystem. A few success stories exemplifying its impact include:

• Enterprise X: Suffering from many connectivity issues and high latency during VoIP calls, they implemented SD-WAN. This resulted in higher call quality and a 30% reduction in network disruption, boosting employee productivity.
• Retail Chain Y: With over 100 locations, Retail Chain Y faced inconsistent voice communication. They adopted SD-WAN, resulting in a single network where VoIP took precedence, and saw a 25% increase in customer satisfaction due to clearer staff communication.
• Financial Firm Z: A financial firm required a reliable and secure network for client communications. SD-WAN provided encrypted lines and optimal call performance, enabling compliance with industry norms and increasing client trust.
