A computing resource virtualization method for a networked test system

Abstract

The invention relates to a calculation resource virtualization method of a networked test system. The method comprises the following steps of step1) using an LXC to realize container virtualization of an apparatus calculating resource; step2) constructing a container network connection model and realizing interconnection among containers; and step3) distributing container network bandwidths. By using the method, under the condition that a network test task is not interfered and destroyed, the idle calculating resource of the apparatus is opened to a system layer so that the apparatus is participated in data processing and operation of the system layer and localization pretreatment of test data. Through a mode of reasonably configuring LXC kernel characteristic, stand-alone LXC container virtualization of an ARM architecture is realized. By using the method of the invention, on aspects of system resource utilization rate increase, master control computer calculating pressure alleviation and network transmission data volume reduction, high feasibility and rationality are possessed; and an actual application demand can be well satisfied.

Description

technical field [0001] The invention belongs to the technical field of networked testing, and in particular relates to a computing resource virtualization method of a networked testing system. Background technique [0002] With the expansion of network technology, the application of network in the field of automatic testing is more and more extensive. Compared with the test bus, the network, with its advantages of openness, compatibility and flexibility, will have better instrument interchangeability, TPS portability and information when constructing an automatic test system. Interoperability; Furthermore, with the improvement of centralized management of test resources, scheduling mechanism and distributed test process, the efficiency of test information transmission and the ability of parallel testing will be greatly improved, thereby achieving higher resource utilization and test efficiency. Therefore, networking will become an important application direction in the fiel...

Problems solved by technology

[0003] At present, although the networked test technology and corresponding specifications have gradually matured, in practical applications, due to the lack of a mature network-based test system architecture and corresponding tools, the network is still used as a test bus, and its advantages are difficult to play. And its disadvantages are even magnified

For example, the 100M / 1000M Ethernet commonly used in network testing, compared with the mainstream test bus PXI or PXIe, its bus bandwidth is obviously insufficient; moreover, the uncertainty of network delay reduces the real-time performance of the test system, making the network test The application effect of the system is greatly reduced; in addition, the intelligence of network test equipment, communication capabilities between devices, and device synchronization and trigger functions are difficult to play a role, information transmission bottlenecks, and test efficiency is difficult to improve

[0004] Networked test instruments are usually intelligent instruments developed using embedded system technology. The instruments themselves have computing and storage capabilities, but these intelligent instruments are only used as peripherals of the main control computer of the networked test system, and the system does not utilize its computing resources. , resulting in a large waste of instrument resources
