Description
Technical Field
The invention relates to the field of computers, in particular to a network performance testing method and device based on multi-system multiplexing network card design.
Background
With the continuous increase of data to be processed, the form of server equipment changes rapidly, and in order to meet the larger calculation requirements under the condition of a limited computer room, a server design with a bias calculation appears at present, that is, under a complete machine system with power supply and heat dissipation of a server, not only one calculation and a storage system used by the calculation but also 2 or more independent calculation systems are integrated. The design is different from a two-way or four-way server, each CPU independently corresponds to one system, a plurality of systems under the same whole machine are mutually independent, different services are processed, and the on-off state of each system is not influenced. In the whole system, under the condition that the heat dissipation is exerted to the limit, the processing speed of the server can be greatly improved. Meanwhile, for users with low computing requirements, more processing service types and low correlation among the processing service types, different services can be deployed on a plurality of systems, and the purchasing cost of the server can be saved for the client. For a server enterprise, the profit of the whole integrated system is high, the integration level of the functions of the main board is high, the assembly and the maintenance are more convenient, and the profit of the enterprise is a better development direction.
Because the integration level of the whole machine system with the design is very high, besides the heat dissipation system and the power supply system are provided by the whole machine, more services are built on the mainboard in a shared mode, such as a server management control module (BMC), a mainboard logic CPLD service and the like. In addition, the network device may be a system in which a plurality of systems are multiplexed. Under the condition of the design, network card equipment with higher bandwidth, such as a 50G/100G network card, can be selected, and when the network card is multiplexed, the network bandwidth is evenly distributed to a plurality of systems, so that cost saving can be realized, and each independently operated system can be ensured to share higher network bandwidth. However, for test verification, the bandwidth in actual use may fall below an acceptable range due to non-time-sharing multiplexing of the network bandwidth and the network card device with a larger bandwidth due to its own reasons and system design. Therefore, in the test validation phase, the bandwidth of the network device must be tested. The design of common multiplexing makes the network bandwidth test unable to reach the nominal value under an independent system, and in order to ensure the availability of the customer deployment service, the network card performance must reach the following standards, namely: the single system bandwidth value does not result in the data being less than the lowest expected value of the total bandwidth and the lowest expected value of the single system bandwidth allocated to the system, and when the whole machine runs, the network bandwidth of the whole machine system is not less than the lowest expected value of the total bandwidth of the used network card equipment. The conventional test method used by the current test team cannot realize monitoring, checking and testing of the network bandwidth test under the design, so that the performance monitoring of the network part under the design is very difficult.

The figures are not necessarily to scale; certain features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention. As one of ordinary skill in the art will appreciate, various features illustrated and described with reference to any one of the figures may be combined with features illustrated in one or more other figures to produce embodiments that are not explicitly illustrated or described. The combination of features shown provides a representative embodiment for a typical application. However, various combinations and modifications of the features consistent with the teachings of the present invention may be desired for certain specific applications or implementations.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
Based on the above purpose, an embodiment of the present invention provides a network performance testing method based on a multi-system multiplexing network card design, as shown in fig. 1, including the following steps:
step S101: one subsystem of a multi-subsystem server is designated as a control end, and an instruction is sent to all the subsystems through the control end to open ports, wherein the ports correspond to ports opened by a network sending end one by one;
step S102: each subsystem simultaneously receives network data from the network sending end to carry out bandwidth test and sends a bandwidth data value tested in each monitoring duration to the control end in real time, so that the control end compares the bandwidth data value with a bandwidth expected value of a single subsystem;
step S103: and the control end adds the bandwidth data values of all the subsystems tested in each monitoring time length, and compares the obtained total bandwidth data value with the total bandwidth expected value of the whole server.
In some embodiments, the method further comprises: before executing the network performance test, the network sending end starts a bandwidth sending service, and all subsystems of the server carry out time synchronization. The whole machine of the network sending end starts the bandwidth sending service, so that the subsystem(s) of the sending end are in a state of constantly and stably outputting data blocks. The whole machine of the sending end only realizes the function of sending data blocks and does not have other work. In one embodiment, as shown in fig. 2, the multiple subsystems of the server (i.e., the receiving end) first synchronize time through a network time protocol server (NTP server). After synchronization is completed, acquiring system time from a plurality of subsystems and comparing the acquired time, if synchronization fails (the time of each subsystem is different), performing time synchronization operation again until synchronization is completed; if the synchronization is successful (the time of each subsystem is the same), one subsystem is designated as a control end in a plurality of subsystems of the receiving end server, and meanwhile, the subsystem also realizes the monitoring and alarm output functions.
In some embodiments, the method initiates a network performance test using iperf or netperf. The sending and receiving module of the network bandwidth is realized based on iperf or netperf software under Linux, and the software can continuously and stably output extremely many data blocks which fully occupy the network bandwidth at the bandwidth output end so as to fully run the bandwidth on a network card link.
In some embodiments, the designating a subsystem of a multi-system server as a control end, and sending an instruction to all the subsystems through the control end to open a port, where the port corresponds to a port opened by the network sending end one to one includes: and the control end sends an instruction for opening the port to all the subsystems and also sends an instruction for specifying the total testing time length, the length of each monitoring time length, the size of a received data block and the thread number of each subsystem bandwidth test. The control end sends a command to the receiving end server complete machine, and the realization function is as follows: and opening a receiving port of the network bandwidth test opened by the sending end, wherein the opened multiple ports correspond to the ports opened by the sending end one by one, and the corresponding mode can be a unique fixed IP (Internet protocol) used for the sending port. In addition, the command to open a port will include a specification of the total test duration, the length of each monitor duration (time space), the size of the received data block (where the data block size is specified to ensure the stability of the total bandwidth using the same size data block), and the number of threads tested per subsystem bandwidth. In one embodiment according to the invention, more than 1 thread number is used, with the aim that for bandwidths above 1Gbit/s, normally one thread cannot reach the desired bandwidth value, as in the following command example:
#iperf-c 10.11.12.13-i 2-w 512k-t 86400-P 8
represents: data is received from the 10.11.12.13 interface, the length of each time space is 2 seconds, the size of each received data block is 512k, the total test time is 86400s, and each test uses 8 threads for testing. Then, the test result is stored, the result in each subsystem is independently stored, and the result is sent to the control end, so that data processing and monitoring are realized. Because the last line of each test result is the bandwidth data of the last time space, that is, the total bandwidth data of all threads in one time space, it is only necessary to monitor the last line of data of all subsystems of the server after each time space is finished, and perform data processing on the last line of data.
In some embodiments, the method further comprises: and in response to the bandwidth expectation value of the whole server not being reached, displaying the alarm word on a screen of the server and recording the logs of all the subsystems. In some embodiments, the method further comprises: and in response to reaching the bandwidth expectation value of the single subsystem and reaching the total bandwidth expectation value of the whole server, continuing to monitor the bandwidth data value in the next monitoring time period.
In an embodiment of the present invention, as shown in fig. 2, a method for implementing bandwidth detection, data analysis and alarm of a single system is as follows: after each time space is finished, capturing the last line (namely the bandwidth data of the previous time space) under each subsystem, extracting the bandwidth data in the line through the shell language of the Linux system, comparing the bandwidth data with the expected bandwidth value of the single system, and displaying a WARNING typeface on a screen and capturing all logs in the subsystem for recording when the expected bandwidth value of the single system is not reached; and if the bandwidth expected value of the single system is reached, continuously monitoring the next time space, and entering the next step of bandwidth detection, data analysis and alarm of the whole system. The method for realizing bandwidth detection, data analysis and alarm of the whole system comprises the following steps: after each time space is finished, capturing the last line (namely the bandwidth data of the previous time space) under each subsystem, extracting the bandwidth data in the line through the shell language of a Linux system, adding the bandwidth data extracted in all the single subsystems in the time space, comparing the obtained total bandwidth data value with the bandwidth expected value of the whole system, and displaying WARNING characters on a screen and capturing all logs in all the systems for recording when the bandwidth expected value of the system is not reached; and if the bandwidth expected value of the whole system is reached, continuing to monitor the next time space.
Where technically feasible, the technical features listed above for the different embodiments may be combined with each other or changed, added, omitted, etc. to form further embodiments within the scope of the invention.
It can be seen from the foregoing embodiments that the network performance testing method and apparatus based on the design of the multi-system multiplexing network card according to the embodiments of the present invention can effectively test the performance of the network bandwidth of a single system in the overall design of the multi-system multiplexing network card, integrate the test conditions of the overall system, and obtain the conclusion whether the design requirement between the network card itself and the motherboard design can be met, so that the deviation and delay caused by the test method can be minimized for both the single system and the overall system, and the design requirement whether the network device itself meets the design requirement can be more accurately reflected, thereby laying a foundation for the improvement of the subsequent design and the realization of the discussion requirement by the customer.
The bandwidth conclusion obtained by using the method provided by the invention is data which is accepted and referred by the manufacturers of network card equipment in the industry. For the network card device itself, since the network card device is related to, for example, a frequency division multiplexing network card device, but the test performance condition of a single card needs to be tested, at this time, a test script needs to be synchronously operated under a plurality of systems, and the performance of a single component can be stably and accurately embodied only by the test result. The invention can realize the synchronous and simultaneous test of a plurality of systems, can reduce the deviation and delay caused by the test method to the maximum extent for a single system or a whole system, and more accurately reflects whether the network equipment per se meets the design requirements.

each subsystem simultaneously receives network data from the network sending end to carry out bandwidth test and sends a bandwidth data value tested in each monitoring duration to the control end in real time, so that the control end compares the bandwidth data value with a bandwidth expected value of a single subsystem;
and the control end adds the bandwidth data values of all the subsystems tested in each monitoring time length, and compares the obtained total bandwidth data value with the total bandwidth expected value of the whole server.
In some embodiments, the steps further comprise: before executing the network performance test, the network sending end starts a bandwidth sending service, and all subsystems of the server carry out time synchronization.
