Connectivity 2017: Let’s Learn About SD-WAN

SD-WAN stands for software-defined networking in a wide area network, which is an approach that simplifies the operation and management of a WAN by separating the networking hardware from its control mechanism. SD-WAN adopts the concept of the implementation of software-defined networking to virtualization technology in order to improve data center operation and management. With SD-WAN, businesses build a higher performance WANs utilizing low-cost internet access and replacement of expensive private WAN connection technologies like MPLS.

With WAN (wide area networks), businesses or companies are able to extend their computer networks over large geographical distances to be able to connect to their remote branch offices and data centers, and to be able to deliver applications and services required in performing their business functions. When businesses try to extend their networks over greater distances and across multiple networks, they often face challenges in operation such as packet loss, jitter, networking congestion and service outages. VoIP calling, streaming media, videoconferencing and virtualized desktops and applications require low latency. 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 the design of SD-WAN products, network problems are addressed by enhancing and replacing traditional branch routers with virtualization appliances, controlling application-level policies, offering network overlay and enabling low-cost consumer-grade internet links acting like a dedicated circuit. With SD-WAN, branch personnel are able to easily and simply setup processes. 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. A a centralized controller is utilized in order to prioritize traffic and set policies, taking into account the availability of network bandwidth and policies to route traffic. By doing so SLA or service level agreements are met by application’s performance.
Short Course on Vendors – Covering The Basics

When it comes to SD-WAN features, it include flexible deployment, resilience, quality of service (QoS) and security with simplified troubleshooting and administration. 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.
