Software-defined networking (SDN) is a network technology designed to make a network agile and easy to manage. SDN implies several kinds of technology intended to build a network as flexible as the modern data center's virtualized server and storage infrastructure. The feature provides you the ability to manage networks using VXLAN technology across OnApp cloud compute resources. Accordingly, you receive a tool to build a level-two network infrastructure with OnApp on top of the existing IP (a level-three) network.
To create an SDN network, take the following steps:
Install and configure the ODL controller.
Create an SDN manager.
Add SDN Manager's connection options, used to connect SDN nodes.
Add SDN nodes to the created SDN Manager.
A schematic of OnApp running SDN is shown below.
