Embodiment 1

[0029] Such as figure 1 As shown, a method for testing the reliability of an SDN controller provided in this embodiment includes the following steps:

[0030] S1: Steps to build a basic test environment, including the following steps:

[0031] S11: Create multiple virtual hosts in physical host A, install a virtualization management system, add a virtual network card to the virtual host, and communicate between the virtual host and the physical host through the trunk network;

[0032] S12: adding the virtual host to other data centers managed by the central controller;

[0033] S13: Create SDN switches with different forwarding modes in each data center;

[0034] S14: The SDN controller associates the above data center;

[0035] S2: Steps of SDN reliability testing; specifically include the following steps:

[0036] S21: the SDN controller creates an SDN network and a router;

[0037] S22: The virtual hosts communicate through the SDN network and the router, and test the ...

Embodiment 2

[0042] This embodiment provides a reliability testing device for an SDN controller, including:

[0043] Build a basic test environment module, create multiple virtual hosts in physical host A, install a virtualization management system, add a virtual network card to the virtual host, and communicate between the virtual host and the physical host through the trunk network; add the virtual host to the central controller Manage other data centers; create SDN switches with different forwarding modes in each data center; SDN controllers associate with the above data centers;

[0044] SDN reliability test module, SDN controller creates SDN network and router; communicates between virtual hosts through SDN network and router, tests network communication pressure between virtual hosts; checks memory usage and CPU usage of SDN controller; outputs Memory and CPU usage of the SDN controller;

[0045] When the memory usage and CPU usage are both less than 50%, double the number of virtua...

Abstract

The invention relates to a reliability test method and device for an SDN controller. The method comprises the following steps: S1, building a basic test environment, and specifically comprises the following steps: S11, building a plurality of virtual hosts in a physical host A, and S12, adding the virtual hosts to other data centers managed by a central controller; S13, creating SDN switches withdifferent forwarding modes in each data center; S14, the SDN controller is associated with the data center; S2, testing the reliability of the SDN; the method specifically comprises the following steps: S21, an SDN controller creates an SDN network and a router; S22, the virtual hosts communicate with each other through an SDN network and a router, and the network communication pressure between the virtual hosts is tested; and checking the memory usage rate and the CPU usage rate of the SDN controller.

Description

technical field [0001] The invention belongs to the technical field of testing, and in particular relates to a reliability testing method and device for an SDN controller. Background technique [0002] SDN is a software-defined network, which can virtualize the network and realize the separation of data forwarding and control. After the separation of control and forwarding, it is more conducive to the centralized control of the network, so that the control layer can obtain the global information of network resources, and carry out global resources according to business needs. Alignment and optimization. It can be seen that the performance and reliability bottleneck of SDN technology lies in the SDN controller. Therefore, the reliability test of the SDN controller is very necessary. [0003] SDN is a new type of network architecture with advantages such as flexibility, intelligence, automation, programmability, resource pooling, and service awareness. And these advantages a...
