Abstract
Centralized network control plane in SDN brings scalability and reliability problem to the network, therefore, the research of multi-controller is appeared. For improving the communication efficiency between the controller and the network device, this paper proposes a loose management strategy to dynamically adjust the frequency of interaction between controllers and network devices. Based on the above idea, firstly, this paper designed the scheme and algorithm of multi-controller loose management. Secondly, this paper quantitatively analyzed the advantages of multi-controller loose management algorithm by mathematically modeling the virtual network deployment success ratio and the management revenue between controllers and network devices. Finally, experiment results show that the multi-controller loose management idea can improve the communication efficiency between the controller and the network device and the controller management efficiency. Simulation results also show that mathematical model accurately predict the performance of loose management algorithm.

Introduction
Software Defined Network (SDN) as a new network architecture [], realizes the centralized, dynamic, and programmable control of the entire network by the virtualization and the separation of application layer, control layer, and data layer.
Like other centralized systems, centralized control in SDN also causes problems of scalability and reliability. Therefore, it is necessary to establish a logical centralized control platform to management the entire network.
In the multi-controller structure of SDN, the controller may not know the status of the network device resources, so a heavy-load network device will probably repeatedly refuse requests from controllers. For improving the communication efficiency between the controller and the network device, this paper proposes a loose management strategy to dynamically adjust the frequency of interaction between controllers and network devices. We consider Virtual Networks (VNs) deployment in SDN as an example. When the number of VNs not deployed by a network device reaches a threshold, the controller will temporarily stop the communication with the network device. After a period of time, the communication between the controller and the network device is resumed. It will improve the management and communication efficiency between controllers and network devices. That is the first contribution of this paper. The second contribution of paper is mathematically modeling of the Virtual Network (VN) deployment success ratio, and the communication benefits between controllers and network devices. Both of the model and simulation results confirm the advantages of loose management.
The remainder of the paper is organized as follows. Section concludes the paper.
Related Work
Currently, the implementation for SDN []. Therefore, many scholars have attracted to the research of multi-controller. Multi-controller in SDN can be classified from four viewpoints.
  1. (1)
    Whole network view controller and local network view controller. The former controllers have a complete information about the entire networks, e.g., HyperFlow [].
  2. (2)
    Multi-management controller and no multi-management controller. The former means that a single network device may be managed by more than one controller, e.g., Devolved [].
  3. (3)
    Single-level controller and multi-level controller. The latter controllers have a root controller as management operations coordinator of local controllers, e.g., Kandoo [].
  4. (4)
    Static management controller and dynamic management controller. Their difference is whether or not the management relationship between network devices and controllers will change the controller with time on. In other words, a network device probably has different controllers in different situations. The typical examples of the former are Onix [].
Based on the multi-controller multi-management, this paper proposes the loose management idea to improve communication efficiency between devices and controllers. There are some researches of improving communication efficiency between devices and controllers, e.g., the literature [].
Scheme and Algorithm of Loose Management for Multi-controller
Control plane and data plane are physically separated in SDN network architecture, which makes centralized configuration and management of the network possible. Based on this, we propose a loose management scheme on network device for multi-controller multi-management, as shown in Fig..

Fig. 1.
Multi-controller multi-management
We assume that required resources of deploying a VN is Picture 2 . Here, the resource is a generic concept and can be referred to memory, bandwidth, CPU, etc., or the composite of various resource types, which depends on users applications. We assume that the life cycle of a VN is Picture 3 , the amount of resources in a network device is Testbeds and Research Infrastructures for the Development of Networks and Communities - image 4 , the average time between two adjacent request of deploying a VN is Testbeds and Research Infrastructures for the Development of Networks and Communities - image 5 , the VN deployment requests arrive according to a Poisson process. When Testbeds and Research Infrastructures for the Development of Networks and Communities - image 6 the amount of resources in a network device is adequate to deploy VN. When Testbeds and Research Infrastructures for the Development of Networks and Communities - image 7 , the amount of resources in a network device is insufficient to deploy VN. The later will cause that the network device is not able to participate in the deployment of VNs, and refuses requests from controllers, which wastes communication and management overheads (including receiving, handling, and replying the request, maintaining the communication state) in both controllers and network devices. Meanwhile, the success ratio of VN deployment is low since more requests are refused.
