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

The invention discloses a method and a device for verifying and testing a switch based on the cooperative realization of software and hardware, and belongs to the field of communication networks. The invention combines the flexibility of software configuration with the high-speed characteristics of hardware design. First, the software generates the configuration information of the data packet size, destination port address and data packet sending time interval under different traffic models; the hardware generates the configuration information according to the configuration information generated by the software. Data flow required for switch testing; statistics on the number of packets and data volume of data packets sent to and received from the switch by hardware, as well as correctness detection and time delay statistics on received data packets; by software through hardware Upload the statistical results of each detection to complete the functional verification of the switch under test, and test the throughput and delay performance. Compared with the existing verification test scheme, the switch verification test method and device have the advantages of low cost, simple implementation, flexible configuration, sufficient function verification and accurate test results.
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...
