Abstract

The present invention discloses a flow monitor for a switch based on software and hardware cooperation. The method comprises: employing Verilog HDL (Hardware Description Language) to edit RTL codes for modulation design and employing the C language edition software to configure a testing platform work mode and a data generation mode based on a programmable device and a software platform. The hardware module includes a collection module configured to calculate the frame data volume of each port according to the throughput rate, a reading control module configured to read frame data and frame information from a memory, a data detection module configured to detect the correction of the frame data, and an extraction and calculation module configured to calculate the delay information of each frame of frame delay. The flow monitor of software and hardware cooperation verification for a switch can realize data collection monitoring according to the related configuration of the software to realize the delay statistics and upload the monitoring data to the software for processing so as to realize the calculation of the throughput rate and upload the throughput rate to the software for statistics. The flow monitor of software and hardware cooperation verification for a switch can conveniently perform verification and performance assessment of the switch and the devices similar to the switch.

Description

technical field [0001] The invention belongs to the communication field and is applied to switch testing, in particular to a switch flow monitor based on programmable logic. Background technique [0002] As the basis of modern large-scale network systems, switches play a very important role in the field of information exchange and high-speed data transmission, especially the research and design of FC high-speed data transmission switches based on optical fiber communication has become a research hotspot in recent years, so high-speed switches Verification and testing of the function and performance of switches has also become an important direction of switch research. [0003] Most of the current high-speed switch verification methods are based on logic analyzers and software platforms for functional and performance verification. However, because logic analyzers are very expensive, the verification cost is high, which is not affordable for ordinary designers. Software verif...
