We’ve started to hear a lot about SD-Branch as a natural successor to SD-WAN, which makes sense as the centrally-orchestrated model is attractive to many enterprises. However, just as we saw with SD-WAN, the term “SD-Branch” is being adopted by many different vendors and service providers to mean what they want, in the absence of any “official” definition.
What is SD-Branch anyway?
Based on most definitions, SD-Branch means delivering more IT infrastructure to branches under a programmable, centrally orchestrated model. Think of it as “SD-WAN plus” – just as you can create templates or profiles in an SD-WAN network, an entire branch template could be generated that defines how the LAN is configured, what wireless LANs are used, how they integrate with the WAN, and what additional compute-based services need to be deployed at the branch.
