The Arrival of SDN 2.0: SmartNIC Performance, COTS Server Efficiency and Open Networking
The era of SDN 2.0 has arrived, with strong emphasis on efficient scaling of server-based networking and moving the brains of networking closer to virtual machines (VMs) and virtual network functions (VNFs) now, and containers in the near future. The importance of open networking – aka hardware and software disaggregation and vendor independence – persists. The era of SDN 1.0 was a period of learning and bringing disaggregation and vendor independence to data center network switches. The largest and most advanced data center operators also innovated and deployed server-based networking.
