SD-WAN 2017: Learning About Its Uses and Benefits to Businesses

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. The concept applied in SD-WAN is the same with the implementation of software-defined networking to virtualization technology for the improving 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. The modern applications that require low latency include VoIP calling, streaming media, videoconferencing and virtualized desktops and applications. There is also an increased need for bandwidth requirements, especially for high-definition (HD) applications aside from low latency. Because of the difficulties associated with network troubleshooting and management, this can result in expensive and difficult WAN capability expansion.

SD-WAN products are specially designed to address network problems through enhancement and replacement of conventional branch routers with virtualization appliances, manage application-level policies and provides network overlay and allowing low-cost consumer-grade internet links acting like a dedicated circuit. Branch personnel deal with setup processes easier and simpler. SD-WAN products are composed of virtual or physical appliances usually placed in small and remote branch offices, larger offices, corporate business data centers and 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. This helps in ensuring that the performance of applications are able to meet service level agreements or SLA.
Questions About Networks You Must Know the Answers To

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 can be achieved by prioritizing bandwidth and increasing application level awareness as well as selection of dynamic path, application sending to faster links and splitting application into two paths for higher and faster performance.
