The present invention provides a method and device for elastically expanding the scale of an SDN controller cluster. The SDN controller cluster includes a supervisory controller and multiple member controllers, and the multiple member controllers are respectively connected to the supervisory controller. The method includes: supervisory control The controller receives the request information of joining the SDN controller cluster or the request information of exiting the SDN controller cluster sent by the member controller; the master controller changes the SDN control according to the request information of joining the SDN controller cluster or the request information of exiting the SDN controller cluster member controllers of the server cluster. According to the present invention, the member controllers in the SDN controller cluster are changed, so that the changed member controllers are sufficient to manage the currently managed switch devices, and the redundant member controllers in the SDN controller cluster perform other services, Realize the dynamic increase or decrease of the number of member controllers in the SDN controller cluster.
Description
technical field [0001] The invention relates to the field of network application technology, in particular to a method and device for elastically expanding the scale of an SDN controller cluster. Background technique [0002] SDN (Software-defined networking, software-defined network) is a network virtualization technology proposed by the Clean State program of Stanford University in the United States. The SDN protocol is used to separate the control plane of network equipment from the data plane. This architecture allows network administrators to re-plan the network with a central control method without changing the hardware equipment. It provides a new method for controlling network traffic and provides a good platform for core network and application innovation. [0003] In the prior art, when creating an SDN controller cluster, it is first necessary to define the number of controllers in the SDN controller cluster. For example, one controller can control 100 switches. N...
