Description

Technical Field

The embodiment of the application relates to the technical field of computers, in particular to a network testing method and device, a storage medium and electronic equipment.

Background

Network function and performance testing is the ability to evaluate and verify the performance and function of a network device, application, or system under different conditions. Such testing typically involves simulating real network environments and traffic to determine the performance of the system under high load, high traffic, or different network conditions. With the development of modern network technology, especially in the fields of large-scale data centers, virtual network function deployment and network security, network complexity is rising and emerging technologies are continuously emerging, so that solutions for testing network functions and performances are more and more complex, and the necessity of testing is also increasing.

The common network test system schemes mainly comprise the following three types:

(1) Network testing is performed using various commercial network testing equipment provided by companies and suppliers, such as network analyzers, load generators, performance monitoring tools, and the like; commercial network test equipment is generally high in price, depends on technical support and maintenance of suppliers and is poor in flexibility;

(2) The software tool on the host machine such as tcpreplay, hping, scapy, tcpping is used for directly performing tasks such as simple network traffic generation, performance test and delay measurement in a mode of generating and simulating network traffic on the host machine, but the mode cannot be used for testing a complex network environment;

(3) Network performance and functionality are assessed using network simulators (e.g., GNS3, cisco VIRL) or emulators (e.g., NS-3) to simulate and test network topologies and scenarios in virtual environments, but testing is done in a virtual manner, failing to completely simulate the complex environment in a real network.

In short, the existing network test mode generally has fixed functions and test modes, and cannot flexibly instruct the test scheme according to different test requirements.

Aiming at the problems of the prior art that the traditional test scheme cannot adapt to changeable test scenes and the test flexibility is poor when the network test is carried out, no effective solution is proposed at present.
