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

SD-WAN or software-defined networking in a wide area network is defined as an approach to designing and deploying an enterprise WAN using software-defined networking to identify the most effective method to route 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. Companies are able to replace expensive private WAN connection technologies like MPLS and use low-cost internet access with SD-WAN.

With WAN or wide area networks, companies are enabled in extending their computer networks over large geographical distances to be able to connect to their remote branch offices and data centers, and 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. The modern applications that require low latency include VoIP calling, streaming media, videoconferencing and virtualized desktops and applications. In addition to that, there is also an increased need in 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. 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. This is to make sure that service level agreements or SLAs are met by applications’ performance.
How I Achieved Maximum Success with Companies

The different features of SD-WANs are resilience, quality of service (QoS) and security with simplified troubleshooting and administration, as well as flexible deployment. An SD-WAN that is resilient should reduce network downtime, automatically switch over to working links if outages happen. 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.
