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. Many companies experiences challenges in operation such as packet loss, jitter, networking congestion and service outages when they 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. In addition to that, there is also an increased need in bandwidth requirements most especially for high-definition (HD) applications. Because of the difficulties associated with network troubleshooting and management, this can result in expensive and difficult 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. When it comes to SD-WAN products, they can be virtual appliances or physical appliances, placed in small and remote branch offices, corporate data centers, larger offices 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 is to make sure that service level agreements or SLAs are met by applications’ performance.
Lessons Learned from Years with Providers
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. In order to gauge the quality of service, bandwidth should be prioritized, and there should be increased application level awareness through dynamic path selection, application sending to faster links and splitting application into two paths for higher and faster performance.
