FREMONT, CA: Software Defined Large Area Network (SD-WAN) market has many key trends increasing its demand. The most significant factor was the transfer of various applications to the Cloud. The work-from-home shift created by COVID-19 is increasing the trend. It means that network and IT administrators must search for more effective methods to manage their networking resources, particularly connectivity, virtual private networks (VPNs), and security. They can no longer depend on legacy circuits, boxes, and edge devices. The IT administrators must utilize cloud-based platforms for their networking tools and functions.
Maintaining sites or branches with several methods to connect to the Internet is another trend attracting the companies. With the implementation of 5G, using applications through the Internet will become more widespread. It is highlighted by several researchers who predict work-from-home trends will continue even after the end of the pandemic. On corporate networks, this will have a significant impact.
A parallel network structure is created by networking through the Cloud with several different endpoints that need to access applications, whether from corporate headquarters, a branch location, the employee's home, or an IoT computer. Unlike Multi-Protocol Label Switching (MPLS) or other legacy networks, SD-WAN is the most effective way to use different connections and transport to bring individuals (and devices) to their applications. SD-WAN allows multiple network access points to act as a single, seamlessly and securely streamlined networking activity.
Connectivity and the Cloud will guarantee continuity of business, SD-WAN is, therefore, a reasonable alternative. It refers to the branch office routing, addresses security problems, VPN, and built-in encryption. It even provides improved cloud app performance and WAN optimization. Many SD-WAN suppliers have also begun to accept residential Internet and cable suppliers as partners to package a lightweight SD-WAN solution with broadband links to boost the user experience for streaming videos or online games. SD-WAN is not only for home-based corporate employees, but it can also even support public sector employees such as those in health care and education.
With the rapid expansion of the pandemic, telehealth and COVID-19 testing services have increased. With SD-WAN, patients at home can consult with physicians, nurses, and caregivers on broadband or other communication types with optimized and consistent efficiency.
