Description

Technical Field

[0001] This invention relates to the field of router performance testing technology, and in particular to a router auxiliary testing device, a router load capacity testing system and method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Router capacity is one of the basic performance indicators of a router. It refers to the number of connections a router can handle simultaneously, including the number of devices connected to the router at the same time and the number of sessions the router can handle simultaneously. The number of connections depends on the router's hardware and software design and its processing power.

[0004] Router load testing is divided into LAN port and Wi-Fi load testing. The existing technical solution is to manually connect the router using auxiliary testing devices such as laptops, mobile phones, and PCs, and use professional software such as network performance testing tools (Iperf or IxChariot) to perform data transmission testing.

[0005] However, due to the large number of client devices, manually connecting the router using auxiliary testing devices such as laptops, mobile phones, and PCs is insufficient to support the testing. Furthermore, manually connecting and switching between different clients is quite complex. For example, each Wi-Fi client requires entering its username and password individually to connect. Setting up a high-concurrency Wi-Fi 6 testing environment is also difficult due to the large number of clients involved. In addition, the network performance testing tools (Iperf or IxChariot) currently used for load testing require operating system support. Summary of the Invention

[0006] To address the aforementioned issues, this invention proposes a router auxiliary testing device, a router load capacity testing system, and a method. The device integrates multiple wireless and Ethernet modules, with each module acting as a network client connected to the router. It automatically controls the connection method and number of each client according to requirements, eliminating the need for manual connection of each client and automatically adjusting the load capacity. This makes it suitable for various router load capacity tests.

It selects the connection method, controls the on / off state of the Ethernet module according to the set number of LAN modules, and configures the username and password of the wireless module according to the number of WIFI modules, thereby connecting the corresponding number of Ethernet modules and wireless modules.

[0014] As an alternative implementation method, the connection method includes sequential connection and concurrent connection;

[0016] The sequential connection process includes: controlling the Ethernet module and the wireless module to connect to the router under test in sequence. After connecting a module, the connection is checked at set intervals. If the connection is successful, a test is performed. If the connection fails, the system is controlled to reconnect. If the number of reconnections exceeds a set threshold, the test is stopped.

[0017] As an optional implementation, the Ping test includes: obtaining the IP address of the currently connected Ethernet module or wireless module, performing a Ping packet test, and outputting the minimum latency, maximum latency, average latency, and packet loss rate for each Ping to each IP.

[0018] As an optional implementation, the data streaming test includes: the Ethernet module and the wireless module receiving streaming data sent by the router under test, and returning the test results to the host computer through the router under test.

[0019] As an optional implementation, the load balancing test includes:

[0020] Under the current settings of LAN and WIFI bandwidth, conduct data flow tests and record the current throughput of each IP.

[0021] After the test time is reached, a certain number of Ethernet and wireless modules are disconnected, and the data flow test is performed again to record the current throughput of each IP.

[0022] The test is repeated a set number of times to determine whether the load balancing of the router under test meets the test standards.

[0023] Secondly, the present invention provides a testing method for a router auxiliary testing device, employing the router auxiliary testing device described in the first aspect, comprising:

[0024] Based on the set number of LAN ports, number of WIFI ports, WIFI username and password, and connection method, the system controls the connection between the Ethernet module and the wireless module and the router under test, thereby controlling the number of LAN ports and WIFI ports connected to the router under test.

[0025] After confirming that the Ethernet module and wireless module have successfully connected, perform Ping test, data flow test and load balancing test on the router under test.

[0026] Thirdly, the present invention provides a router load capacity testing system, comprising: a host computer, a router under test, and the router auxiliary testing device described in the first aspect;

[0045] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0046] Example 1

[0047] This embodiment provides a router auxiliary testing device, including:

[0048] Several Ethernet modules, each connected to the router under test;

[0049] Several wireless modules, each connected to the router under test;

[0050] The processor controls the number of LAN and WIFI connections to the router under test by controlling the connection between the Ethernet and wireless modules and the router under test. After successful connection, it performs Ping, data flow and load balancing tests on the router under test.

[0051] The following is combined Figure 1 The router auxiliary testing device is described in detail.

[0052] In this embodiment, the processor (MCU) is connected to the Ethernet module (ETH module) through the IO control module to control the number of routers under test. During load balancing testing, since the number of loads is changing, the IO control module can automatically control the connection and disconnection between the Ethernet module and the router under test, eliminating the need to manually plug and unplug the network cable.

[0053] In this embodiment, the processor connects to the wireless module (wifi module) via a 485 bus module and controls the connection and disconnection between the wifi module and the router under test via AT commands, thereby controlling the number of wifi clients accessing the router under test.

[0054] As an alternative implementation, the processor uses an STM32F103, which has 5 UART ports and can control a 485 bus module and multiple I / O control modules.

[0055] As an alternative implementation, the IO control module uses IO808, which can control the on / off state of eight Ethernet modules.

[0056] As an alternative implementation method, the 485 bus module can configure the parameters of each module simultaneously to achieve parameter uniformity.

[0057] In this embodiment, the Ethernet module is connected to the router under test via a network cable and a switch. In the data flow test and load balancing test, it is used to receive the flow data sent by the router under test and return the test results such as throughput, latency, and packet loss rate of this line.

[0058] In this embodiment, the wireless module connects to the router under test by entering a username and password. In the data flow test and load balancing test, it is used to receive the data flow sent by the router under test and return the test results such as throughput, latency, and packet loss rate of this line.

[0059] In this embodiment, the processor is also connected to the host computer via a serial port module. The host computer configures parameters such as the number of LAN devices, the number of Wi-Fi devices, the Wi-Fi username and password, and the connection method. The connection method is divided into one-to-one connection and concurrent connection. The host computer sends the number of LAN devices, the number of Wi-Fi devices, the Wi-Fi username and password, and the connection method to the processor via the serial port module, thereby controlling the connection between the Ethernet module and the wireless module and the router under test.

[0060] In this embodiment, the processor controls the Ethernet module's on / off state via the IO control module according to the set LAN load capacity, configures the Wi-Fi module's username and password via the 485 bus module according to the Wi-Fi load capacity, and selects the connection method after configuration.

[0061] like Figure 2 As shown, specifically:

[0062] (1) If concurrent connections are selected;

[0063] (1-1) After starting the test, a connection check is performed;

[0064] (1-2) Set the interval (e.g., 30s), and determine whether the connection is successful based on the set number of LAN loads, number of WIFI loads, and number of current connections. After successful connection, the host computer obtains the IP address currently connected to the router under test and sends relevant test data to it for testing.

[0065] (1-3) If the connection still fails after 3 attempts, disconnect all connections and retry the connection. If the connection fails after 3 attempts, it will indicate that the current load data is inconsistent with the device. In this case, the tester needs to reduce the load and retest.

[0066] (2) If you choose to connect one by one:

[0067] (2-1) After the test begins, the MCU controls the Ethernet module or the WiFi module to connect to the router under test in sequence.

[0068] (2-2) After connecting to a client, the host computer will check whether the connection is successful at set intervals (e.g., 10s). If the connection is not successful, the MCU will control the reconnection. If the reconnection fails 3 times, the test will stop and prompt that the current load data is inconsistent with the device. The tester needs to check whether the test environment is abnormal or reduce the load and retest.

[0069] In this embodiment, Ping test is also known as load capacity test. Ping test does not require a large amount of data. As long as the connection is normal and Ping can be completed, it is sufficient. The main test is the maximum number of clients that the router under test can support.

[0070] The testing steps include: obtaining the IP address of the currently connected Ethernet or wireless module; Ping testing uses 64-byte packets by default; and finally outputting the minimum latency, maximum latency, average latency, and packet loss rate for each ping to each IP address. Figure 3 As shown.

[0071] The host computer connects to the router under test and obtains the IP address of the current connection by reading the router's log information.

[0072] In this embodiment, the data flow test, also known as the load performance test, requires testing the router's maximum transmission throughput, latency, packet loss rate, etc.

[0073] The testing steps include: using the Ethernet module and wireless module as terminal services, and the host computer as the control terminal, performing a streaming test on the Ethernet module and wireless module using TCP.

[0074] like Figure 4As shown, the Ethernet module and wireless module receive the streaming data sent by the router under test (DUT) and return the test results to the host computer control terminal via the DUT. Finally, they return data such as throughput, latency, and packet loss rate. Figure 5 As shown.

[0075] In this embodiment, the load balancing test mainly tests whether the throughput of each client can remain in a state of balanced traffic distribution when the number of routers changes.

[0076] The testing steps include:

[0077] Under the current settings of LAN and WIFI bandwidth, conduct data flow tests and record the current throughput of each IP.

[0078] Once the test time is reached, the MCU controls the disconnection of a certain number of Ethernet and wireless modules, and the test is performed again, while recording the current throughput of each IP.

[0079] Repeat the process three times to determine whether the load balancing function of the router under test meets the test standards.

[0080] The router auxiliary testing device in this embodiment integrates multiple wireless modules and Ethernet modules, and automatically connects to the router under test. Each module is equivalent to a network client connected to the router. The connection between the wireless module and the router under test is controlled by the 485 bus module, and the connection between the IO control module and the router under test is controlled by the IO control module to control the on / off state of the Ethernet module's network cable.

[0084] After confirming that the Ethernet module and wireless module have successfully connected, perform Ping test, data flow test and load balancing test on the router under test.
