Connecting complex enterprise networks from afar, a software-defined wide area network or SD-WAN is becoming the lifeline of most of the companies. Most enterprises have had enough complications involving their network, and so, most of them are converting to SDNs. SDN continues to make the networks faster, safer, user-friendly, and cost-efficient to build and operate. SD-WAN simplifies enterprise connectivity networks to branch offices and far away locations. It provides the required flexibility, centralized monitoring, centralized control, and reduces the costs on a wide area network (WAN).
The layout of a network that consists of hardware, software, communication protocols, connectivity, and mode of transmission is what is referred to as network architecture. There are different types of network topologies—star, bus or line, loop, and mesh network—which can be arranged in different ways as LAN, WAN, and metropolitan area network (MAN).
SD-WAN features a lot of abilities. It combines network links, pooling in all of the resources so that all of the applications and services are available in one location. SD-WAN can customize the bandwidth and connectivity to meet the specific needs of network services, users, or locations. It can configure each device without manual override and centrally manage and define policies and network traffic.
SD-WAN streamlines the workflow integrates third-party applications and extends WAN to multiple cloud services. Adopting SD-WAN has various operational and financial benefits. Enterprises that use SD-WAN can easily add or remove WAN connections. Using SD-WAN, a company can easily add or reduce the bandwidth. SD-WAN is much cheaper when compared to multiprotocol label switching (MPLS). It effectively pulls the full potential of the available network connections without the worries of maintaining backup links. SD-WAN encrypts WAN traffic and improves network security. As it uses high-performance connections that are secure, it eliminates penalties imposed by MPLS networks. Its ability to integrate with an existing MPLS network enables SD-WAN to adjust traffic flows to accommodate network conditions. SD-WANs improve customer satisfaction, boosting the overall performance of a company's corporate network. It is faster and more flexible, using software to relay traffic through different connections such as LTE, broadband, and MPLS and opts for the best one to transfer data effortlessly from one location to another. SD-WANs reduce jitters in data transfer and improve prioritizing traffic in an enterprise’s network.
SD-WAN will continue to evolve, providing users with better connectivity, allowing them to leave corporate LAN, and promises to revolutionize networking.
