Network test system and construction method and device of test network

Abstract

The invention provides a network test system and a construction method and device of a test network, the network test system comprises a plurality of network devices, wherein the plurality of network devices form a topology network; an NS-3 network simulator is installed in each network device; the network equipment is configured with equipment nodes, and the equipment nodes are established for the network equipment to run an NS-3 network simulator in a simulation manner; an application layer, a transmission layer and a network layer are configured in the equipment nodes, and the application layer, the transmission layer and the network layer are all constructed by network equipment operation NS-3 network simulator simulation; and the equipment nodes are in control connection with the bottom link layer and the physical layer of the network equipment, so that the powerful functional characteristics of the NS-3 network simulator in network protocol processing are met, and the network protocol development work is reduced. The workload of secondary development of all components on the NS-3 network simulator is reduced, and meanwhile, the problem that performance indexes of underlying hardware cannot be tested by using the NS-3 network simulator is solved.

Description

Technical field [0001] The present invention relates to the field of network testing, and in particular, to a network test system, a construction method and apparatus for testing a network. Background technique [0002] NS-3 Network Simulator is an internationally mainstream open source network simulator that simulates various types and scale of network structures in the Physical World. In the virtual network of the NS-3 simulation, the nodes and channels in the network topology are abstract into a variety of C ++ classes. The connection operation of the node and channel is abstract into different C ++ objects association. 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 local area networks in wireless networks and LTE, etc. [0003] The NS-3 network simulator is mainly used to simulate the test network environment. Before the simulation test, the network of the network needs to b...

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
