At its core, SD-WAN technology is software that is designed to simplify network management. By providing a centralized platform, it allows organizations to more easily manage their networks. This platform is then used to configure, deploy, and maintain the network's settings and security protocols. This makes it easier for IT departments to maintain all the appropriate settings and security protocols across multiple locations in a single place.
At a basic level, SD-WAN technology uses virtualization to create multiple virtual networks over different physical transmission media such as fiber optic cables, copper cables, wireless connections, or any combination of these. By using virtualization, SD-WAN can take advantage of existing bandwidth and add capacity as needed. This allows for greater scalability, ensuring that all connected locations can adequately function while offering increased performance and speed.
The virtual networks created with SD-WAN can be segmented into different priority zones, or 'quality of service' (QoS) levels. Qualified personnel can then prioritize certain channels or applications to ensure that the most important tasks, such as real-time videoconferencing or VoIP calls, get the highest priority. This is especially useful for companies dealing with sensitive data, as it helps ensure that their critical assets are always available and secure.
When it comes to security, SD-WAN technology offers several advantages. It is able to detect and prevent malicious activity on the network by implementing security protocols and policies. Additionally, SD-WAN solutions typically feature encryption technology, ensuring that all data is securely encrypted during transmission. This prevents snooping and other forms of unauthorized access, making it ideal for organizations that need to safeguard their sensitive information.
In terms of cost savings, SD-WAN technology is a great option for businesses looking to reduce their WAN expenses. Because multiple virtual networks can be created over existing infrastructure, costs associated with deploying a wholly new network can be avoided. This also eliminates the need for additional hardware and wiring, resulting in reduced capital expenditure and operating costs.
Finally, SD-WAN technology is highly reliable. It is designed to automatically detect and restore connections when outages occur. This means that business continuity can be maintained, even in the event of a major disaster or outage, as SD-WAN solutions can quickly restore connections within minutes.
These are just some of the ways in which SD-WAN technology can help improve your organization's network infrastructure. As the technology continues to evolve and become more sophisticated, businesses can expect to receive even more benefits from it. Whether you are looking for improved security, cost savings, scalability, or reliability, SD-WAN solutions are a great choice for organizations of all sizes.
