Software-defined network simulation system and method based on openstack

Abstract

The invention provides an OpenStack based software defined network simulation system. The system comprises a virtual machine creating module, a simulation network setting module and a test module, wherein the virtual machine creating module creates multiple virtual machines according to requirements, the simulation network setting module arranges at least one software defined network controller and at least one software defined network switch in the created virtual machines according to requirements so as to establish a corresponding network topology network, and the test module tests whether the arranged software defined network controller and software defined network switch satisfy requirements according to the established network topology structure. The system uses the test module to test whether the arranged software defined network controller and software defined network switch satisfy requirements, so that the needed controller and switch can be developed according to requirements, the setting flexibility of the software defined network is improved, and the design cost is reduced. The invention also provides a software defined network simulation method.

Description

technical field [0001] The present invention relates to software-defined network technology, in particular to an OpenStack-based software-defined network simulation system and method. Background technique [0002] At present, in the traditional software-defined network (Software Defined Network, SDN) architecture based on OpenStack deployment, a dedicated SDN controller is deployed as the Plugin of the Neutron component of OpenStack that provides basic functions of network management. When the OpenStack cloud computing platform will When network configuration, management and other operation commands are sent to the SDN controller, the controller will calculate the forwarding path according to the operation command, convert the forwarding path into OpenFlow flow table information, and send it to the SDN switch [0003] However, in the process of designing the SDN network using the above deployment method, when the customer's design requirements for the SDN network change repe...

Problems solved by technology

[0003] However, in the process of designing the SDN network using the above deployment method, when the customer's design requirements for the SDN network change repeatedly, the SDN network that has been set up needs to be modified repeatedly, resulting in low flexibility for deploying the SDN network. , resulting in a relative increase in design cost
