SD-WAN 2017: Learning About Its Uses and Benefits 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. Companies are able to replace expensive private WAN connection technologies like MPLS and use low-cost internet access with SD-WAN. 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. Almost all modern applications require low latency such as 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. 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. 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 is to make sure that service level agreements or SLAs are met by applications’ performance.
The Ultimate Guide to Networks
When it comes to SD-WAN features, it include flexible deployment, resilience, quality of service (QoS) and security with simplified troubleshooting and administration. 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.
