Network test system, method and device for constructing test network

Abstract

The present invention provides a network test system, a method for constructing a test network and a device thereof. The network test system includes a plurality of network devices, and the plurality of network devices form a topological network; each network device is equipped with a NS-3 network simulator; the network The device is configured with a device node, and the device node is simulated and established for the network device running NS-3 network simulator; the application layer, transport layer and network layer are configured in the device node, and the application layer, transport layer and network layer are network devices running NS-3 The network simulator is simulated and constructed; the underlying link layer and physical layer control connection between the device node and the network device not only satisfies the powerful features of using the NS‑3 network simulator in network protocol processing, but also reduces the development work of the network protocol. It also reduces the workload of secondary development of all components on the NS-3 network simulator, and also solves the problem that the underlying hardware performance indicators cannot be tested using the NS-3 network simulator.

Description

technical field [0001] The invention relates to the technical field of network testing, in particular to a network testing system, a method and a device for constructing a testing network. Background technique [0002] NS-3 network simulator is a mainstream open source network simulator in the world, which can simulate various types and scales of network structures in the physical world. In the virtual network simulated by NS-3, the nodes and channels in the network topology are abstracted into various C++ classes. The connection operations of nodes and channels are abstracted as associations between different C++ objects. Through this abstraction, various types of network topologies can be simulated in the NS-3 program, such as point-to-point and bus networks, wireless LAN and LTE in wireless networks, etc. [0003] NS-3 network simulator is mainly used in the test phase to simulate the test network environment. Before the simulation test, it is necessary to modify the c...

AI Technical Summary

Problems solved by technology

For projects with fewer nodes, which can actually build a physical network environment, unnecessary workload is generated

Moreover, such as testing software running resource occupancy, physical layer interface performance, signal interference in wireless network transmission, etc. do not belong to the scope of NS-3 capabilities
