Detailed Description
In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 1A and fig. 1B, in which fig. 1A is a schematic flowchart of a method for testing a network speed of a local area network according to an embodiment of the present invention. Fig. 1B is a schematic diagram of a connection relationship among a terminal, a router, and a speed measurement server to which the embodiment of the present invention is applied. The method of the embodiment can be executed by a speed measuring server, and can be applied to a scene that a user tests the network speed of the local area network, wherein the speed measuring server is a special web server and is mainly used for testing the network speed.
The method for testing the network speed of the local area network provided by the embodiment can comprise the following steps:
s110: and receiving an access request of a user for accessing the speed measuring server through the terminal browser, and returning a speed measuring interface to the terminal browser.
Illustratively, the terminal browser of the user accesses the speed measurement server through the router. When a user has a requirement for testing the network speed of the local area network, a convention address can be input in an address bar of a terminal browser to initiate an access request to a speed measuring server, the speed measuring server returns a speed measuring interface to the terminal browser after receiving the access request, the speed measuring interface is displayed on a current page window of the terminal browser, and the user can input different speed measuring instructions through the speed measuring interface according to actual requirements to test the network speed.
For example, the method for obtaining the speed measurement interface by the terminal browser in this embodiment may be similar to a method for obtaining a router setting interface when a router is set by a browser in common use, where an agreed address input in an address bar of the terminal browser may be a recognized address or a special address specified by a manufacturer, and the terminal browser may be a common browser such as an IE browser, a fire fox browser, or a google browser.
Preferably, the speed measurement instruction in this embodiment may include an upload speed measurement instruction and a download speed measurement instruction.
Preferably, when only one router to be tested needs to be tested, the terminal browser accesses the LAN port of the browser to be tested and is directly connected to the speed measurement server through the WAN port of the router to be tested.
Or as shown in fig. 1B, when a plurality of routers to be tested need to be tested (only one router is shown in the figure), the terminal browser accesses the speed measurement server through the router to be tested and the testing partner router connected in series with the router to be tested. For example, a terminal browser accesses a LAN port of a browser to be tested, a WAN port of the browser to be tested is connected to one LAN port of an accompanying router, and the accompanying router is connected to a speed measurement server through another LAN port, where the accompanying router is used to support testing of multiple routers to be tested.
S120: and receiving a speed measurement instruction which is input by a user through a speed measurement interface and simultaneously transmits a plurality of test files.
Illustratively, the speed measurement interface displayed by the terminal browser comprises an upload speed measurement button, a download speed measurement button and an input box, wherein a user inputs and transmits multiple copies of the same test file in the input box, for example, simultaneously transmits 7 copies of the same test file, and then clicks the upload speed measurement button or the download speed measurement button to send a speed measurement instruction to the speed measurement server.
It should be noted that, in the prior art, when a terminal browser transmits a file, it is usually a stream (a network connection) transmission, and at this time, the transmission rate from the terminal browser to the speed measurement server is limited, and the peak value of the transmission rate of the local area network cannot be tested. In this embodiment, multiple streams (multiple network connections) are used for transmission, and the peak value of the transmission rate of the local area network can be accurately tested by setting to transmit multiple copies (for example, 7 copies) of the same test file at the same time.
S130: and controlling a packet grabbing tool to grab the data packet when the test file is transmitted according to the speed measuring instruction.
For example, after receiving the speed measurement instruction, the speed measurement server triggers a transmission (uploading or downloading) action of transmitting the test file to start transmitting the test file, and sets a filtering condition for the packet capturing tool to control the packet capturing tool to capture the data packet when the test file is transmitted.
For example, the bale plucker may be a conventional open source bale plucker such as firebug, httpwatch, or fixdler. When uploading the test file, the uploading filtering conditions are set for the packet capturing tool, such as: the ip.dst ═ 192.168.15.54 and dtcp.dstport ═ 8000, which indicates that all packets are packets flowing to the speed measurement server (ip.dst ═ 192.168.15.54) and flowing to the test server speed measurement program (tcp.dstport ═ 8000). When downloading the speed measurement file, the download filtering conditions are set for the packet capturing tool, such as: the source of the data packet is the tachometer server, and the data packet is from the tachometer server tachometer program (tcp. src ═ 8000).
S140: and calculating the peak value and the mean value of the transmission rate of the local area network according to the speed measurement data per second obtained when the packet grabbing tool grabs the data packet.
For example, when 7 test files are transmitted simultaneously through 7 network connections, the packet capturing tool counts the transmission flow of each network connection within each second, adds the data corresponding to the 7 network connections to obtain the speed measurement data per second when the test files are transmitted, and calculates the peak transmission rate value and the average transmission rate value of the local area network according to the obtained speed measurement data per second after the test files to be transmitted are finished. The specific calculation method of the transmission rate peak value and the transmission rate mean value, which is provided in the second embodiment of the present invention, is an optional implementation manner, and is not described herein again.
The method of the embodiment can effectively test the network speed of network terminal products such as a CableModem router, a wireless router or a convergence set-top box with a router function in the local area network.
In summary, in the technical solution, the speed measurement server receives an access request from a user to access the speed measurement server through a terminal browser, returns a speed measurement interface to the terminal browser, receives a speed measurement instruction input by the user through the speed measurement interface and simultaneously transmits a plurality of copies of a test file, controls a packet capturing tool to capture a data packet during transmission of the test file according to the speed measurement instruction, and calculates a transmission rate peak value and a transmission rate average value of the local area network according to speed measurement data per second obtained when the packet capturing tool captures the data packet. The user can conveniently send the speed measurement instruction to the speed measurement server through the speed measurement interface on the terminal browser, the speed measurement operation is simple and convenient, the flow between the terminal browser and the speed measurement server is counted by the packet capturing of the speed measurement server, and the speed measurement accuracy is high.
Example two
Please refer to fig. 2, which is a flowchart illustrating a method for testing a network speed of a local area network according to a second embodiment of the present invention. The main difference between this embodiment and the first embodiment is that, on the basis of the first embodiment, the transmission rate peak value and the transmission rate average value are additionally transmitted to the terminal, so that the terminal displays the content of the transmission rate peak value and the transmission rate average value through a speed measurement interface on a browser of the terminal, and further, an optional implementation manner of S140 in the first embodiment is provided.
The method for testing the network speed of the local area network provided by the embodiment can comprise the following steps:
s210: and receiving an access request of a user for accessing the speed measuring server through the terminal browser, and returning a speed measuring interface to the terminal browser.
S220: and receiving a speed measurement instruction which is input by a user through a speed measurement interface and simultaneously transmits a plurality of test files.
S230: and controlling a packet grabbing tool to grab the data packet when the test file is transmitted according to the speed measuring instruction.
S240: and calculating the peak value and the mean value of the transmission rate of the local area network according to the speed measurement data per second obtained when the packet grabbing tool grabs the data packet.
Optionally, S240 may include the following two steps S241 and S242, where:
s241: and selecting the maximum value from all the per-second speed measurement data obtained when the packet grabbing tool grabs the message as the peak value of the transmission rate.
For example, 7 copies of the same test file are transmitted simultaneously, and 10 seconds are spent, 10 pieces of speed measurement data per second are obtained, and one data with the largest value is selected from the 10 pieces of data, namely the transmission rate peak value of the local area network.
S242: and counting all speed measurement data per second according to a preset statistical algorithm and the size of the test file to obtain a transmission rate mean value.
For example, for transmitting test files with different sizes, different methods are adopted to calculate the average value of the transmission rate of the local area network.
Preferably, the preset statistical algorithm may be:
if the size of the test file is smaller than the preset threshold value, calculating a first average value of all speed measurement data per second, filtering the speed measurement data per second of which the value is smaller than the first average value in all the speed measurement data per second, calculating a second average value of the rest speed measurement data per second, and taking the second average value as the transmission rate average value. For example, if the size of the test file is less than 100 megabits, the transmission time is shorter than 6 seconds, 6 data per second of velocity measurement data corresponding to each second are obtained, a first average value of the 6 data is calculated, the data of which the beginning and the end are smaller than the first average value in the 6 data are filtered out, for example, the first two seconds and the last second 3 data are filtered out, a second average value of the remaining 3 data is continuously calculated, and the second average value is used as the transmission rate average value of the local area network.
And if the size of the test file is not smaller than the preset threshold value, filtering the speed measurement data per second corresponding to the first 1 second and the last 1 second of transmission, calculating a third average value of the remaining speed measurement data per second, and taking the third average value as the transmission speed average value. For example, if the size of the test file is not less than 100 megabits, the transmission time is longer than 15 seconds, 15 data in total of speed measurement data per second are obtained, only 2 data corresponding to the first second and the last second need to be filtered out, the third average value of the remaining 13 data is calculated, and the third average value is used as the transmission rate average value of the local area network.
S250: and transmitting the transmission rate peak value and the transmission rate average value to the terminal so that the terminal displays the transmission rate peak value and the transmission rate average value through a speed measuring interface on a terminal browser.
Illustratively, after the speed measurement server calculates the average value of the transmission rate of the local area network, the speed measurement server transmits the calculation result to the terminal, and the calculation result is displayed on a speed measurement interface on a terminal browser.
In summary, in the technical solution, the speed measurement server receives an access request from a user to access the speed measurement server through a terminal browser, and returns a speed measurement interface to the terminal browser, receives a speed measurement instruction that the user transmits a plurality of copies of a test file while inputting through the speed measurement interface, controls a packet capturing tool to capture a data packet during transmission of the test file according to the speed measurement instruction, calculates a transmission rate peak value and a transmission rate average value of the local area network according to a preset statistical algorithm according to speed measurement data per second obtained when the packet capturing tool captures the data packet, and transmits a calculation result to the terminal to be displayed on the speed measurement interface.
