Finding Ways To Keep Up With Networks

SD-WAN 2017: Learning About Its Uses and Benefits 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. 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. Almost all modern applications require low latency such as VoIP calling, streaming media, videoconferencing and virtualized desktops and applications. Aside from low latency, there is an increasing need for bandwidth requirements most especially for high-definition (HD) applications. There is a high occurrence of difficult and expensive WAN capability expansion due to difficulties related to network troubleshooting and management. 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. 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. By doing so SLA or service level agreements are met by application’s performance.
Lessons Learned from Years with Providers
The different features of SD-WANs are resilience, quality of service (QoS) and security with simplified troubleshooting and administration, as well as flexible deployment. A resilient SD-WAN must reduce network downtime, automatically switching over to working links with real-time outages detection. 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.
