Problems solved by technology

However, the current problem is that there is no uniform standard for the API interface provided by the SDN controller, so the upper-layer network management software needs to interact with the APIs of multiple SDN controllers, which brings difficulty in integration

Embodiment Construction

[0087] (1) Experimental method

[0088] The experimental verification of Policy-driven Software Defined Networking Method-PDSDN, a multi-tenant policy-driven software-defined network method for cloud data centers, is divided into two parts: functional verification and performance verification. The functional verification tests the effectiveness of the PDSDN system through some typical application scenarios , performance verification tests the performance of the PDSDN system in a multi-tenant concurrent operating environment.

[0089] (2) Function verification

[0090] The functional verification experiment is carried out through the Openstack cloud platform. In the neutron network management module of Openstack, external SDN controllers can be supported through plug-ins. In the implementation of the current Openstack Havana version, the supported SDN controllers include Floodlight, Ryu, etc. Because the PDSDN system is developed based on Floodlight, it can also be recognize...

Abstract

The invention belongs to the technical field of cloud computing and novel networks, and particularly provides a multi-tenant policy-driven type software-defined networking method for a cloud data center. The method includes the specific steps of tenant policy defining, user definition policy authority limiting, policy conflict solving and policy file parsing and executing. According to the method, a network is configured through policy defining, tenants can define virtual networks, virtual firewalls and the like of the tenants in a visual mode without writing programs or using a programming interface provided by a software-defined networking controller; management on a cloud computing platform and management on an SDN controller are unified; the networks are managed through policy parsing, so that higher efficiency can be achieved, computing resources, such as a CPU, of the software-defined networking controller are saved, and the time for processing requests of the tenants through the controller is shortened. On the premise that user friendliness is ensured, the performance can be close to the performance achieved when calling is conducted by a local API, and meanwhile the performance is quite better than the performance achieved when calling is conducted by an RESTAPI.

Description

technical field [0001] The invention belongs to the technical field of cloud computing and data center networks, and in particular relates to a multi-tenant policy-driven software-defined network method for cloud data centers. Background technique [0002] There are several problems in the current research on the application of software-defined network to cloud data center management. The main problems are that the management logic of administrators is complex and difficult to implement, the efficiency of SDN controller is not high, and tenants cannot define their own network policies. Referring to some public cloud platforms such as Amazon, most of them manage various resources of tenants in cloud computing through tenant-defined policies. Therefore, the starting point of the design of the present invention is that the cloud data center can also use a policy-driven approach to network management, and after expanding the original policy, it is easy to integrate different typ...
