An Overview of SD-WAN Load Balancing for WAN Connections

Abstract

Enterprises are revolving around different business strategies and new technologies to be ahead in the game. It may be cloud or SaaS, mobility, BYOD, network security, or unified communications. The existing and new entrepreneurs are in search and in need of the best and latest tech. Among which, the cloud is most eminent. It has gifted certain presents to the clan of businessmen- easy data transfer among intra-geographical locations, ease of storage, etc. Along with these advantages of the cloud, its security plays an equally important role. Here enters SD-WAN, which renders: Granular Security, Agile Network, Better Speed, Low Operating Cost, Higher UX, etc. Software-Defined Wide Area Network is an approach, which distributes the traffic that uses (software-defined networking) SDN technology across WANs to find out the best possible route for traffic flow among different geographical stations. Technically, it can be defined as SD-WAN is a technology that optimizes the operations over WANs with cloud-based management and automation. Load balancing is a traditional networking technique commonly used within data centers, while Software Defined WAN is a newer technology that can use load-balancing capabilities for WAN connections. This research article gives the overview of SD-WAN and load balancing in SD-WAN.
