Bringing SDN to Reality

It is difficult to get one definition of SDN - interpretations vary. The purist would say it’s a separation of the data and control planes using a controller to communicate between the two. This was the original thesis of OpenFlow. Network virtualization, as driven by VMware/Nicira and Arista, has emerged as one of the most compelling applications of SDN technology across a broad set of customers. However, our roots in an open and programmatic set of interfaces run deep, to the very core of how EOS has been designed. Our suite of APIs allows applications to better integrate with and drive network infrastructure. Arista believes that SDN is about scaling the control and data plane with programmatic and open interfaces in a useful way – not about replacing existing network architectures and topologies.
