SD-WAN is quickly becoming a popular choice for businesses of all sizes. What exactly is SD-WAN? What can you do to make the most of it? In this blog post, we will explain SD-WAN in 7 easy steps. We’ll cover everything from what SD-WAN is, to how it works and why you should consider using it. So, if you’re looking for a comprehensive guide to SD-WAN, look no further!
About SD-WAN
SD-WAN stands for software-defined wide area network. In simple terms, it is a way to connect multiple locations using the internet instead of traditional leased lines. It is used to connect branch offices to data centers, cloud resources, and each other. The SD-WAN creates a VPN or virtual private network over the internet. VPNs are typically used to connect remote users to a private network, but they can also be used to connect multiple locations. SD-WAN offers many benefits over traditional WANs, including increased bandwidth, reduced costs, and improved performance. Businesses use SD-WANs for a variety of applications, such as voice-over IP (VoIP), video conferencing, and data backup.
How A SD-WAN function?
SD-WAN uses a technique called tunneling to create secure, reliable connections over the internet. Tunneling involves encapsulating data in a packet and sending it through an intermediary network (the tunnel). The destination computer decapsulates the packet and reads the data. Tunneling is an efficient way to send data because it doesn’t require a dedicated connection between the two computers. This makes it possible to use lower-cost internet connections instead of more expensive leased lines. SD-WAN also uses Quality of Service (QoS) to prioritize traffic and ensure that critical applications always have enough bandwidth. QoS automatically routes traffic over the best path based on latency, jitter, and packet loss.
Why should you use SD-WAN?
There are many reasons why you should consider using SD-WAN for your business:
Increased Bandwidth
SD-WAN can bond multiple internet connections together to increase bandwidth. This is important for businesses that rely on cloud-based applications or need to transfer large files between locations.
Reduced Costs
SD-WAN can reduce your WAN costs by using lower-cost internet connections instead of more expensive leased lines. In addition, SD-WAN devices are typically less expensive than traditional routers.
Improved Performance
SD-WAN uses Quality of Service (QoS) to prioritize traffic and ensure that critical applications always have enough bandwidth. This can improve application performance and make your network more responsive. These features help ensure that critical applications always have enough bandwidth and are not impacted by latency or jitter.
Simplified Management
SD-WAN devices are easy to deploy and manage, even for large networks. Most SD-WAN vendors offer centralized management tools that make it easy to add, remove, and configure devices. This simplifies your network management and reduces the need for specialized staff.
In conclusion, SD-WAN is a great choice for businesses of all sizes. It offers increased bandwidth, reduced costs, and improved performance. If you’re looking for a comprehensive guide to SD-WAN, look no further! Thanks for reading.
