SD-WAN or software-defined networking in a wide area network refers to the approach simplifying operation and management of a WAN by separating or decoupling the networking hardware from its control mechanism and designing and deploying an enterprise WAN using software-defined networking in order to determine the most effective method of routing traffic to remote locations. SD-WAN adopts the concept of the implementation of software-defined networking to virtualization technology in order to improve data center operation and management. SD-WAN allows companies to create high performing WANs with the use of low-cost internet access, and replacing expensive private WAN connection technologies like MPLS.
WANs or wide area networks enable companies in extending their computer networks over large geographical distances in order to connect to their remote branch offices and data centers, delivering applications and services required in performing business functions. With WAN legacy, companies face challenges in operation such as jitter, networking congestion, packet loss, and service outages when they attempt to extend their networks over greater distances and across multiple networks. Almost all modern applications require low latency such as VoIP calling, streaming media, videoconferencing and virtualized desktops and applications. Aside from low latency, there is an increasing need for bandwidth requirements most especially for high-definition (HD) applications. The difficulties related to network troubleshooting and management can result in difficult and expensive WAN capability expansion.
With SD-WAN products, network problems are addressed by enhancing and replacing traditional branch routers with virtualization appliances, controlling application-level policies, provision of network overlay and allowing low-cost consumer-grade internet links acting like a dedicated circuit. SD-WAN makes setup processes simpler for branch personnel. SD-WAN products are either physical or virtual appliance which is placed in corporate data centers, larger offices, small remote branch offices or cloud platforms. In order to prioritize traffic and set policies, a centralized controller is used, with SD-WAN taking into account availability of network bandwidth and policies to route traffic. By doing so SLA or service level agreements are met by application’s performance.
Doing Networks The Right Way
The different features of SD-WANs are resilience, quality of service (QoS) and security with simplified troubleshooting and administration, as well as flexible deployment. SD-WAN resiliency is determined by reducing network downtime, featuring real-time outages detection and automatic switching over to working links. Quality of service is determined by selection of dynamic path, application sending to faster links and splitting application into two paths for higher and faster performance.
