In order to better understand above-described embodiment, be described for the embody rule scene of a clustered node controller monitoring method below.
In SDN controller cluster, there are 1 master node control and 10 slave node controllers.Master node control receives the registration of these 10 slave node controllers, and is sorted from 1 to 10 by these 10 slave node controllers according to the time order and function of registration.
Afterwards, master node control and the 1st slave node controller are set up logic and are connected and control the 1st slave node controller and the 2nd slave node controller and set up logic and be connected and control the 2nd slave node controller and set up logic with the 3rd slave node controller and be connected ... by that analogy, be connected until control the 9th slave node controller sets up logic with the 10th slave node controller, last master node control is set up logic with the 10th slave node controller and is connected, and forms ring topology.
Afterwards, set up heartbeat between master node control with the 1st slave node controller to be connected and to control to set up between the 1st slave node controller with the 2nd slave node controller heartbeat and be connected and control to set up heartbeat between the 2nd slave node controller with the 3rd slave node controller and be connected ... by that analogy, until control the 9th slave node controller and set up heartbeat between the 10th slave node controller and be connected, set up heartbeat between last master node control with the n-th slave node controller to be connected, define closed annular circuit physically.
