Abstract

The embodiment of the invention discloses a task transferring method and a controller, and is applied to a controller trunking system. The method comprises the steps of calculating an attenuation coefficient of each task on controller by the controller when the task is transferred to other controllers in a controller trunking, wherein the attenuation coefficient of the task is in negative correlation with the quantity of information needed to be transferred by the task transferring and the information transferring duration; determining, by the controller, a task to be transferred and a target controller to which the task to be transferred is transferred according to the attenuation coefficient; transferring the task to be transferred to the target controller by the controller. By adopting the task transferring method and the controller provided by the embodiment of the invention, the task distribution in the controller trunking system is more balanced, and the whole performance of an SDN (Software Defined Network) is improved.

Description

technical field [0001] The present application relates to the field of information technology, in particular to a method and controller for task migration. Background technique [0002] After the network in the traditional information technology (English: Information Technology, IT) architecture is deployed and launched according to business needs, if the business needs change, it is very cumbersome to re-modify the configuration on the corresponding network devices (routers, switches, firewalls). matter. In the rapidly changing business environment of the Internet / mobile Internet, the high stability and high performance of the network are not enough to meet business needs, and flexibility and agility are more critical. What software-defined network (English: Software Defined Network, SDN) does is to separate the control rights on the network devices, managed by a centralized controller, without relying on the underlying network devices (routers, switches, firewalls), shiel...
