20 SDN for Merchant Silicon Landscape Windows Server: Power your business

21 What is Software Defined Networking? A software-defined networking (SDN) architecture defines how a networking and computing system can be built using a combination of open, software-based technologies and commodity networking hardware that separate the control layer and the data layer of the networking stack. Open Networking is the foundation for SDN (but is not SDN!) In the SDN architecture, the splitting of the control and data forwarding functions is referred to as disaggregation because these pieces can be sourced separately, rather than deployed as one integrated system. In turns: SDN focuses on network stack disaggregation 21

Therefore each Leaf Switch would require 16 Spine to Leaf connections
