The network test platform based on the cloud infrastructure supports network tests needing to be accessed to actual equipment or actual network links, and compared with a scheme that network simulation software such as Cisco Packet tracker and GNS3 is only used for building a network environment, the network test platform based on the cloud infrastructure is richer in network equipment and network links, can meet various network test requirements, and is not limited by the number of types of simulation equipment.
In one possible implementation, the operation of the network test includes starting and executing the network test, pausing and resuming the network test, and ending the network test.
It should be noted that, the starting of the network test may refer to that the resource orchestrator starts to obtain, according to the configuration of the network test of the test user, the test resource required for performing the target network test from the test resource pool and provide the test resource to the test user, so as to set up a network environment for performing the target network test; the executing the network test may refer to acquiring a test file uploaded or modified by the test user, and running a test program in the test file to implement the execution of the network test.

The following describes a cloud infrastructure-based network testing method provided in an embodiment of the present application, where the method may be applied to a cloud infrastructure-based network testing platform as described above, and the method may include:
A. the resource orchestrator 2 obtains configuration parameters of a test user on a target network test, where the configuration parameters include configuration parameters of a test node and configuration parameters of a test network, checks the correctness of the configuration parameters, generates a configuration table of the target network test if the check result is correct, and stores the configuration table in the user resource and test resource management module 31.
For example, fig. 2 shows a schematic structural diagram of a possible target network test, a test user a and a test user b may interact with an interactive portal in a network test platform based on a cloud data center through respective physical servers, specifically, the test user a or b may configure the target network test through a visual test operation module in the interactive portal, set the name of the target network test as "NDN network test", set the test type as "network test", set the test purpose and the point as description words related to the test, set 3 test nodes according to the target network topology, set a system mirror image as "Ubuntu mirror image" for each test node, set the number of CPU cores as "2", set the disk capacity as "40G", the memory capacity as "8G", set the network segment as "data center network segment", select the network segment as "172.16.0.0", set the bandwidth of each link of the network topology as "10Mbps", the packet loss ratio as "20%", the time delay as "50ms", set the type of the test data to be acquired as "test node, set the bandwidth of each link of the network node as" 10Mbps ", and set the network delay ratio of the network test node, so that the user b may create the network test environment including the network test and the user resource configuration.
B. Under the condition that the test user starts the target network test, the resource orchestrator 2 acquires a configuration table of the target network test from the user resource and test resource management module 31, acquires a test resource slice corresponding to each test node of the target network test from the test resource pool 1 according to configuration parameters in the configuration table, and installs an operating system for each test node;
the visual test operation module 32 displays a graphical operation interface and a command line operation interface of the operation system of the test node, so that a test user can operate the target network test according to a preset test plan, and specifically, the test user can run a test program in a mode of uploading and modifying a test file in the operation interface of any test node;
under the condition that the test user pauses the target network test, the user resource and test resource management module 31 modifies the test state of the target network test into pause; when the test user finishes the target network test, the resource orchestrator 2 releases the test resource corresponding to the target network test and returns the test resource to the test resource pool 1, and the user resource and test resource management module 31 modifies the test state of the target network test to be finished.
By way of example, fig. 3 is a schematic diagram illustrating a process of performing a network test by a possible test user, and in conjunction with fig. 2, the test user interacts with the network test platform through an interactive portal to implement configuration and control of the network test, observation and derivation of test data, where the control of the network test may include starting and executing, pausing and continuing, and ending of the network test; in addition, the process of acquiring the test resource slice from the test resource pool by the resource orchestrator may include that the interactive portal generates a corresponding test resource calling instruction according to the configuration condition of the test user on the network test, and the resource orchestrator sends the calling instruction to the test resource pool, receives a corresponding response, and provides the response to the cloud management platform under the condition of acquiring the test resource calling instruction, so that the cloud management platform can provide the corresponding test resource slice to the test user through the interactive portal.
It should be noted that, when the test user suspends the target network test, although the user resource and test resource management module 31 modifies the test state of the target network test to suspend, the resource orchestrator 2 does not release the test resource corresponding to the target network test, that is, the target network test in the suspended state still occupies the original test resource.
In addition, test resources and links corresponding to different test users and different test requirements are completely isolated from each other and do not influence each other, so that efficient, reliable and safe operation of each network test and credibility of test results are guaranteed.
C.
