A review of SD-branch and its progression from SD-WAN
Jennifer English | April 03, 2019
The goal of software-defined branch is to merge network functions and management into a single platform, but the branch architecture still lacks maturity, despite some early deployments. Changes in the networking industry can take years, if not decades. Distributed enterprises have consistently searched for the coveted thin branch, which reduces the branch hardware footprint, for example. Software-defined WAN and software-defined branch can initiate this consolidation, but a few hurdles block the way. One such barrier: existing branch network equipment. With SD-WAN, enterprises can capitalize on their existing WAN connectivity. SD-WAN creates a virtual overlay over the infrastructure and enables enterprises to configure policies that specify which traffic should travel over which path.
As SD-WAN continues to mature, enterprises seek additional capabilities, like security for traffic that goes to and from cloud environments or network analytics that provide granular network data.
