Problems solved by technology

[0003] Among them, the passive network monitoring technology detects errors by tracking normal traffic, but because the current data packets cannot trigger certain errors, there is a problem of low coverage; the active network testing technology diagnoses errors by injecting probes into the network, but due to The generation of probes requires a large number of servers, so there is a problem of high overhead
[0004] To sum up, the current network testing methods have problems of low coverage and high overhead in the process of troubleshooting runtime rule errors on the programmable data plane

Embodiment Construction

[0056] It should be understood that the specific embodiments described here are only used to explain the present disclosure, not to limit the present disclosure.

[0057] In traditional networks, due to issues such as complex design and hardware process limitations, it often takes several years to add new functions or new network protocols to switching chips, making it difficult for network equipment to meet the development requirements of rapid new protocols and network protocols. Aiming at the challenge of slow evolution of network equipment, the team led by Professor Nick MckWeon of Stanford University proposed a protocol-independent programmable data plane architecture. Based on the reconfigurable matching action table, the architecture builds a protocol-independent data packet processing pipeline through programmable control logic, and can quickly add new network functions to the switching chip. Through the programmable data plane architecture, equipment manufacturers or ...

Abstract

The invention provides a network test method and system, a storage medium and electronic equipment, and the method comprises the steps: obtaining a target binary decision diagram matched with a flow table rule and a P4 program; generating and updating a probe according to the target binary decision diagram, the topology and the rule updating event; forwarding the probe, and writing an action corresponding to the flow table rule into the probe; and when the probe returns to the server, checking the probe to obtain a detection result of a rule error in the operation process. According to the network test method and system, the storage medium and the electronic equipment provided by the embodiment of the invention, the binary decision diagram can be used for representing the P4 program and the flow table rule, so that the low overhead of network resources is realized, and the full coverage of the flow table rule can be realized.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a network testing method, system, storage medium and electronic equipment. Background technique [0002] Currently, network testing methods for troubleshooting runtime rule errors on the programmable data plane usually include passive network monitoring technology and active network testing technology. [0003] Among them, the passive network monitoring technology detects errors by tracking normal traffic, but because the current data packets cannot trigger certain errors, there is a problem of low coverage; the active network testing technology diagnoses errors by injecting probes into the network, but due to The generation of probes requires a large number of servers, so there is a problem of high overhead. [0004] To sum up, the current network testing methods have the problems of low coverage and high overhead in the process of troubleshooting runtime rule errors on th...
