FPGA (field programmable gate array) based software-hardware coordinated network test system and method

Abstract

The invention discloses an FPGA (field programmable gate array) based software-hardware coordinated network test system and an FPGA based software-hardware coordinated network test method, which relate to the field of network test. The method comprises the following steps: configuring a configuration information register for network test ports P1 and P2 corresponding to an FPGA test device, generating data frames according to configuration information and sending the data frames, counting the number of the data frames sent within a unit time and the total number of the sent data frames; and carrying out check and classification on the received data frames by the network test ports P1 and P2, caching the data frames and counting the number of the data frames received within a unit time and the total number of the received data frames, converting the formats of the received data frames and storing the converted data frames, and analyzing various sent and received statistical information so as to realize the analysis and diagnosis on the forwarding performance of network equipment. The system and method disclosed by the invention are low in cost, can meet the test requirements on the development and production of network equipment, and can improve the test efficiency.

Description

technical field [0001] The invention relates to the field of network testing, in particular to an FPGA-based software and hardware cooperative network testing system and method. Background technique [0002] Network testers play an extremely important role in the development, production, and network construction of network equipment. The commonly used test methods for diagnosing, testing network equipment, and building networks are basically divided into two categories. The first category It adopts the 10 / 100 / 1000Mbit / s network port of the existing PC (Personal Computer) plus some commonly used application software, such as EtherPeek and Sniffer software in the network protocol analysis software. At the same time, the received data packets are analyzed. This method can be used to test and diagnose whether the network equipment or the network can forward the data packets. However, because the use of this method is limited by PCs and application software, The network port of ...

[0002] Network testers play an extremely important role in the development, production, and network construction of network equipment. The commonly used test methods for diagnosing, testing network equipment, and building networks are basically divided into two categories. The first category It adopts the 10 / 100 / 1000Mbit / s network port of the existing PC (Personal Computer) plus some commonly used application software, such as EtherPeek and Sniffer software in the network protocol analysis software. At the same time, the received data packets are analyzed. This method can be used to test and diagnose whether the network equipment or the network can forward the data packets. However, because the use of this method is limited by PCs and application software, The network port of the PC cannot send data packets at a linear speed (that is, according to the full flow rate) of 100 / 1000Mbit / s, and can only reach a flow rate of more than a dozen megabytes, so that the forwarding performance test, such as the throughput test, etc. The machine does not have a 10Gbit / s network port, so it is impossible to test the equipment with a 10Gbit / s network port, and the test method using a PC generally requires two PCs to perform the test of the two ports. It brings inconvenience; the second type of test method is to adopt a special tester, commonly used testers produced by companies such as Spirent (Spirent), Ixia (Yijia), can provide the required test requirements, but this type Test equipment is very expensive. For most companies, they can only have a small amount of this type of test equipment, but it is far from meeting the application requirements for the development and production of network equipment.

Since there is no test equipment with low cost and can meet the test requirements at the same time, the development and production efficiency of network equipment is low
