Getting Down To Basics with Vendors

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 SD-WAN concept is somehow similar with the virtualization technology software-defined networking implementation, 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. 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. There is also an increased need for bandwidth requirements, especially for high-definition (HD) applications aside from low latency. The difficulties related to network troubleshooting and management can result in difficult and expensive 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. 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 SD-WAN a centralized controller is used to be able to prioritize traffic and set policies, taking into account the policies and availability of network bandwidth to route traffic. This helps in ensuring that the performance of applications are able to meet service level agreements or SLA.

The different SD-WAN features include flexible deployment, quality of service (QoS), resilience 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 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.
