The invention provides an FPGA (Field Programmable Gate Array)-based method for generating RFC 2544 testing data streams. The FPGA-based method for generating the RFC 2544 testing data streams at least comprises setting testing configuration information through users; generating into a testing request sequence according to the testing configuration information; enabling every testing request to be generated into a testing data packet correspondingly and the testing request sequence to generate the testing data streams correspondingly. The invention also provides an FPGA-based device for generating the RFC 2544 testing data streams. The FPGA-based device for generating the RFC 2544 testing data streams comprises a plurality of groups of testing request generation modules and a testing data stream generation module; the testing request generation modules are used for generating into a plurality of groups of testing request sequences; the testing data stream generation module which is connected with the plurality of groups of testing request generation modules is used for obtaining the plurality of groups of testing data streams which are generated through the plurality of groups of testing request sequences and outputting. The method and device can generate the RFC 2544 testing data streams which satisfy requirements according to testing requirements such as user setting length, speed, abruptness and testing duration and based on the FPGA.
Description
technical field [0001] The invention relates to the testing field of data equipment, in particular to a method and device for generating RFC2544 test data streams based on FPGA. Background technique [0002] The RFC2544 protocol is an international standard proposed by the RFC organization for evaluating network interconnection devices (firewall, IDS, Switch, etc.). It mainly stipulates in detail the specific test methods and the submission form of the performance evaluation parameters defined in RFC1242. RFC2544 stipulates many parameters for testing different network devices, mainly including the four most important parameters: Throughput, Lost Rate, Latency, and Back-to-Back. Among them, the throughput rate reflects the maximum data flow that the device under test can handle (without losing data packets); the packet loss rate reflects the ability of the device under test to withstand a specific load; the delay reflects the speed at which the device under test processes d...
