What is SDN Controller?

An SDN controller is used to control network devices such as switches. You can add an external SDN controller to the Cloud and use the controller to control external switches and other network devices. By adding an SDN controller, you can take over SDN networks of hardware switches to reduce network latencies and improve VXLAN network performances.
  • Before you can add an SDN controller to the Cloud, plan for management networks in advance, and complete the basic configurations of the SDN controller.
  • Currently, the Cloud supports only H3C VCFC SDN controllers.
    Note: If you use VCFC to configure hardware SDN, configure the mapping between VLAN and VXLAN on VCFC in advance.
