NANOG's video: SDN Controllers For Service Provider Network Automation - 2022 View

Software defined networking has promised the ability for network operators to create networks driven by intelligent applications interacting with network devices with open standard interfaces. Most realize this lofty goal of SDN has not been realized since its origination 10+ years ago. However, in the last several years there has been renewed interest driven by both operators and vendors in advancing SDN and Intent Based Networking architectures and controllers. The key to enabling multi-vendor SDN control are standards regarding software components, how the data they contain is exposed, and how service intent is expressed in the network. In this session we will briefly cover the history of SDN controllers and then discuss the current work in the industry to increase adoption of open multi-vendor SDN solutions .
