The SDN controllers cluster is called to determine the type of message of the initial message data, and according to the message class
Type determines module to be controlled；
Module to be controlled described in the SDN controllers clustered control is called, based on the initial message data generation flow table.
Further, following steps are realized when the network optimization program is executed by processor：
When detecting virtual machine with external network communication, the SDN controllers clustered control hardware switch pair is called
The virtual machine is handled.
Further, following steps are realized when the network optimization program is executed by processor：
When performing the call operation of the SDN controllers cluster, the call operation day of the SDN controllers cluster is recorded
Will, and the current state of the call operation daily record is registered as wait state；
After the call operation runs succeeded, the current state of the call operation daily record is registered as success status,
And after the call operation performs time-out, the current state of the call operation daily record is registered as timeout mode；
By the call operation daily record that current state is success status, and the call operation day that current state is timeout mode
Will write operation log database.
Further, following steps are realized when the network optimization program is executed by processor：
Call operation of the current state as success status is read from the operation log database using interval preset time
Daily record；
According to current state for success status call operation daily record by Neutron databases in the OpenStack
Data are synchronized in the database of the SDN controllers cluster.
In the OpenStack data of Neutron databases be synchronized to the SDN controllers cluster database it
Afterwards, the call operation daily record that current state is success status is deleted from the operation log database.
