Abstract

The embodiment of the invention discloses a dynamic cloud storage SDN controller configuration method and a dynamic cloud storage SDN controller configuration device based on overall optimization. Themethod comprises the steps of building a first generation of particle swarms by using each controller in an SDN as a particle, determining the fitness of each particle in the first generation of particle swarms, and using the first generation of particle swarms to serve as a current iteration particle swarm; computing a local optimal solution of each particle and an overall optimal solution in the current iteration particle swarm; determining a distribution node corresponding to each controller; evolving the speed and position of each particle in the current iteration particle swarm; updatingthe fitness of each particle in the current iteration particle swarm; returning to execute the operation of computing the local optimal solution of each particle and an overall optimal solution in the current iteration particle swarm until an iteration end condition is met; and configuring each controller in the SDN by using the overall optimal solution determined when iteration ends. Therefore,the SDN controller is reasonably deployed under the condition of meeting a rated task load constraint of the controller, and thus the overall delay in the network becomes minimal.

Description

technical field [0001] Embodiments of the present invention relate to network communication technologies, and in particular to a global optimization-based dynamic cloud storage SDN controller configuration method and device. Background technique [0002] With the continuous development of new applications, the continuous growth of network and storage devices, and the application of the Internet of Things, the amount of communication data is growing faster and faster, and data calculations are becoming more and more complex. Traditional network structures and service models are difficult to meet business needs. Flexibility needs. [0003] SDN (Software Defined Network, Software Defined Network) is a new type of network innovation architecture. Its core is to build a network system that separates the forwarding plane and the control plane. The whole structure is divided into three layers: application layer, data processing control layer and basic Device layer. SDN can debug ...
