According to the software and hardware collaborative implementation-based switch verification test method and device, the software configuration flexibility and a hardware design high-speed characteristic are combined; software generates configuration information comprising data package sizes, destination port addresses and data package sending time intervals under different flow models; hardware generates data flows required by a switch test according to the configuration information generated by the software; the hardware performs statistics on the number of packages and the data volume of data packages which are sent to and received from the switch and performs correction detection and time delay statistics on the received data packages; the software achieves a functional verification and a throughput and time delay performance test of the measured switch according to various detection statistics results uploaded by the hardware. Compared with the existing verification testing scheme, the software and hardware collaborative implementation-based switch verification test method and device have the advantages of being low in cost, simple in achievement, flexible in configuration, full in functional verification and accurate in testing result.

Description

technical field [0001] The invention belongs to the field of communication networks, and in particular relates to a method and a device for verifying and testing switches realized by software and hardware cooperation. Background technique [0002] At present, the Internet has become an important interactive medium in life, and an intelligent switching network with high bandwidth, high reliability, and economical ease of use has become an inevitable trend. As the foundation of modern large-scale network systems, switches play a very important role in the field of information exchange and high-speed data transmission. The performance of switches determines the performance and stability of the network. It is necessary to continuously improve the performance of switches. Throughput and time delay are the two most important performance indicators of switches. The so-called throughput (Throughput) refers to the maximum amount of data that the switch under test can forward without...

Problems solved by technology

Among them, professional testing equipment is very expensive, the price is tens of thousands to hundreds of thousands of dollars, and the testing cost is high.

Patent "Throughput Performance Test Processing Engine Embedded in Ethernet Switch Chip and Its Implementation Method", this solution occupies the hardware resources of Ethernet switch chip and increases the cost of the chip; the test processing engine is embedded in the chip, which has poor flexibility , only applicable to Ethernet; using switches to generate data packets cannot implement various traffic models, and the generated test data flow is relatively single, which cannot simulate various possible real network environments; only mentions throughput performance testing, and cannot test time delay and other key performance indicators

[0007] To sum up, the software-based functional verification platform cannot accurately simulate the network environment, the accuracy of the verification results is not high, and performance testing cannot be performed

Professional test equipment for performance testing of switches is expensive and lacks sufficient flexibility
