Course facts

  • Knowledge of the concepts and tools required for network automation (APIs such as REST, RESTCONF and NETCONF, but also tools needed in the programming environment)
  • Knowledge of the individual elements and their context
  • Stable foundations in Network Programmability and SDN

SDN offers new opportunities in network automation and is changing the way we run networks. The SDN Controller makes it easy to access the network using scripts and programs (Network Programmability). The course provides an easy to understand introduction to the new concepts. In addition to the concepts of SDN, interfaces such as REST and NETCONF, the YANG data model and other elements frequently used in connection with network automation are explained.
