[0052] Before introducing the test method for file transmission stability based on traffic restoration file provided by the present application, the background content involved in the present application is introduced first.

[0053] The test method, device and computer readable storage medium for file transmission stability based on traffic restoration file provided by the present application can be applied to a processing device, for processing sample traffic files to improve the diversity of test cases, so that the file transmission stability of the file transmission link can be tested more accurately.

[0054] The test method for file transmission stability based on traffic restoration file mentioned in the present application can be a test device for file transmission stability based on traffic restoration file, or a server, a physical host or a user equipment (User Equipment, UE) and other different types of processing devices integrated with the test device for file transmission stability based on traffic restoration file. Among them, the test device for file transmission stability based on traffic restoration file can be realized by hardware or software, and the UE can be a terminal device such as a smart phone, a tablet computer, a notebook computer, a desktop computer or a personal digital assistant (Personal Digital Assistant, PDA), and the processing device can be set by device cluster.

[0055] It should be understood that for the processing device herein, the device form can be adjusted according to the needs of the tester or the working environment in actual application, and in addition, it can also be adjusted according to the device involved in the file transmission link which needs to test the file transmission stability, and the specific device form can be flexibly adapted according to the actual situation.

[0056] Next, the test method for file transmission stability based on traffic restoration file provided by the present application is introduced.

[0057] First, refer to Figure 1 , Figure 1A flowchart of a test method for file transmission stability based on traffic restoration files is shown. The test method for file transmission stability based on traffic restoration files provided by the present application can specifically include the following steps S101 to S103:

[0058] In step S101, a sample traffic file is obtained. The traffic file format refers to the file format obtained by converting a file into traffic during file transmission.

[0059] It can be understood that the sample traffic file obtained here is obtained in the initial stage and is used to test the file transmission stability of the target file transmission link. In a general sense, the file transmission stability is the stability of the process of transmitting the converted traffic file from the sender to the receiver in the link.

[0060] For the sample traffic file, it can be an actual traffic file captured from the target file transmission link in real time, an actual traffic file captured from the target file transmission link in a historical time period, an actual traffic file captured from other transmission links, or a manually configured traffic file. The configuration approach is obviously flexible and does not need to be particularly limited.

[0061] For the sample traffic file, the traffic file format obtained by converting a file into traffic during file transmission is obviously the file format that can be used in the actual file transmission link. It is generally a common traffic file format, and of course, it does not exclude that a specific new traffic file format will be specially configured in some application environment.

[0062] As a practical implementation, the traffic file format of the sample traffic file can be PCAP traffic file format, which is a commonly used datagram storage file format in file transmission links. This file format can save the message content and has its fixed storage format.

[0063] In step S102, the sample traffic file is converted from the corresponding initial file transmission protocol into a target traffic file of a different file transmission protocol.

[0064] It can be understood that after studying the related test schemes in the prior art, it is found that when using a purchased network tester for testing, manual configuration is needed to simulate the file transmission protocol adapted to the tester, and the corresponding network configuration also needs to be selected. The protocol is often single and expensive, and the operation is complex. These will all lead to limited test accuracy in actual application, and it is difficult to determine the real and comprehensive situation of the file transmission stability of the target file transmission link.

[0065] Therefore, the application is directly configured in the test tool, after obtaining the sample traffic file, the traffic file conversion of different file transfer protocols is directly performed on the sample traffic file in an automatic manner, so that the diversity of the traffic file (test case) for testing is conveniently and significantly expanded, and thus the inconvenience that the existing technology needs to replace a new file transfer protocol for each round of testing when testing different file transfer protocols is eliminated.

[0066] In this way, the effect of automatically generating network transmission traffic of various protocols by inputting a sample traffic file is realized.

[0067] Among them, as another practical implementation manner, the different file transfer protocols specifically include any combination of FTP protocol, HTTP protocol, HTTP / 2 protocol, SMTP protocol, POP3 protocol, IMAP protocol, IPV4 protocol, and IPV6 protocol and the like.

[0068] In addition, in addition to improving the diversity of the sample by converting the file transfer protocol, the application can also improve the diversity of the sample in other ways in actual application.

[0069] For example, the application can also modify the form of the file itself to simulate the impact on network traffic that may be caused in the file transfer link.

[0070] As another practical implementation manner, the processing of the target traffic file can specifically include:

[0071] Converting the sample traffic file from the corresponding initial file transfer protocol to a first traffic file of different file transfer protocols;

[0072] Performing environment simulation processing on the first traffic file to obtain a second traffic file as a target traffic file, and the environment simulation processing refers to the simulation processing of the network environment of the file processing of the input traffic file.

[0073] It can be understood that the processing of processing the initial sample traffic file into the first traffic file can refer to the description in the foregoing content, which will not be repeated here.

[0074] After obtaining the first traffic file converted by the protocol, the environment simulation processing specially configured by the application can be performed to introduce the impact of different application environments on network traffic.

[0075] It can be understood that the influence of the environment on the network traffic can not only involve the special file processing of the specific environment on the network traffic, but also involve the possible or random file processing of the specific environment on the network traffic, which corresponds to the complex scenarios that can theoretically exist in practical applications.

[0076] Therefore, in the case of improving the diversity of the sample through the conversion of the file transfer protocol, the diversity of the sample can be further improved by simulating the influence of the environment on the network traffic.

[0077] Further, in the environment simulation process, as another practical implementation manner, the file processing in the environment simulation process can specifically include at least one of the processing of delay, repetition, discard, fragmentation, overlap, segmentation, out-of-order, and packet loss.

[0078] It can be found that the processing involved herein is mostly the modification of the location of the file content, such as the processing of repetition, fragmentation, overlap, and out-of-order (content is not missing or distorted), and a small part is the missing of the file content, such as the processing of discard and packet loss, and the modification of the file transfer timing, such as the processing of delay, which modifies the network traffic (traffic file) in different aspects in a complex and changeable manner. Therefore, in addition to the file transfer protocol, the environment that can theoretically be involved can be freely combined, thereby more significantly improving the diversity of the sample.

[0079] Step S103, based on the target traffic file, testing the file transfer stability of the target file transfer link.

[0080] After obtaining the target traffic file with the diversity configured in the application, specific test work can be carried out to test the difference between the actual file obtained after the target file transfer link transmits the target traffic file and the file that should theoretically be obtained, so as to evaluate or quantify the file transfer stability of the target file transfer link.

[0081] Specifically, as another practical implementation manner, the testing process herein can specifically include the following contents:

[0082] restoring the target traffic file into a first target file;

[0083] transferring the target traffic file through the target file transfer link, and listening to a second target file restored by the target file transfer link;

[0084] determining the file transfer stability of the target file transfer link according to the comparison result of the first target file and the second target file.

[0085] It is easy to understand that the first target file is a file that should be obtained in theory after the target traffic file passes through the target file transmission link. The first target file can be measured once or multiple times by using a relevant restoration algorithm, so that the finally determined file is the first target file that should be obtained in theory.

[0086] On the other hand, the second target file is obtained by listening to the target traffic file after the target traffic file is transmitted to the target file transmission link. It should be understood that the second target file can be obtained by restoring the traffic file received by the receiver in the target file transmission link, or can be obtained by restoring the traffic file received by the receiver in the target file transmission link. More simply, the second target file can be obtained by a test tool or by the receiver in the target file transmission link. The difference lies in whether the file restoration processing is performed by the receiver.

[0087] After obtaining the first target file that should be obtained in theory and the second target file that is actually obtained after transmission, the two files can be compared. The difference between the two can be quantified by the comparison result. Obviously, if there is no difference, it means that the file transmission stability of the target file transmission link is better and consistent with the theory. Otherwise, it means that there is a problem with the file transmission stability of the target file transmission link. An abnormal prompt or alarm prompt can be output to promote the arrangement of related maintenance and update to improve the file transmission stability.

[0088] Further, the file transmission stability determined by the present application can also be distinguished by the stability degree through the relevant quantification range, for example, four stability degrees of stable, relatively stable, relatively unstable and unstable, and for example, five stability degrees (quantified by scoring) of 0-30, 30-50, 50-70, 70-90 and 90-100. Obviously, the specific quantification mechanism can also be flexibly adjusted, and the quantification target is the comparison result of the two in a specific factor.

[0089] For the comparison processing of the two, that is, the specific factor for comparison mentioned in the previous paragraph, as another specific implementation manner, the specific value can be a value calculated by different characteristic value algorithms such as MD5 value, SHA1 value or SHA256 value.

[0090] Such a value, in a simple way, can be understood as a value obtained by extracting an information digest. Only a completely consistent file can calculate the same value under the algorithm. Therefore, if the MD, SHA1 value or SHA256 value of two traffic files is consistent, it can be considered that the two traffic files are the same, otherwise the two traffic files are not the same.

[0091] For the MD5 value, it can be understood as a value calculated by MD5 Message-Digest Algorithm, which is a cryptographic hash function, and can generate a 128-bit (16-byte) hash value;

[0092] For the SHA1 value, it is also a value calculated by a cryptographic hash function, which generates a 160-bit (20-byte) hash value called message digest, and the hash value is usually represented by 40 hexadecimal numbers;

[0093] For the SHA256 value, it also belongs to the SHA algorithm, which is an improved algorithm based on the cryptographic hash function involved in the SHA1 value. For any length of message, the calculated SHA256 value is a 256-bit hash value, which is equivalent to an array of 32 bytes in length, and is usually represented by a hexadecimal string of length 64.

[0094] Correspondingly, the comparison result of the first target file and the second target file mentioned in the above content can be the comparison result of the MD5 values calculated by the two, or can be the comparison result of the SHA1 values calculated by the two, or can be the comparison result of the SHA256 values calculated by the two, or can be the comparison result of the characteristic values calculated by the two under other characteristic value calculation algorithms.

[0095] In addition, it should be understood that the characteristic value calculation algorithm involved here can also use characteristic value calculation algorithms other than MD5, SHA1 and SHA256, or even self-developed characteristic value calculation algorithms, which can be configured as needed.

[0096] In order to further understand the above content, it can also be understood in combination with the content of a test tool configured in the specific application.

[0097] Referring to Figure 2 A functional schematic diagram of the test tool of the present application is shown, which shows the related functions that can be configured on the test terminal, the packet sending machine and the device side of the test tool (it should be understood that the actual functions are not limited to the scope shown in the figure) to achieve the test goal of file transmission stability of the file transmission link.

[0098] As a specific implementation of the test tool, it can include the following modules:

[0099] The PCAP conversion module can output a plurality of PCAP files containing the original file transmission protocol by inputting the original file

[0100] Network simulation module, can be through the PCAP file of the last step, according to the application example is simulated, such as fragmentation size 800, output converted PCAP file.

[0101] Traffic playback module, can be through the PCAP file of the last step, according to the application example is simulated, such as fragmentation size 800, output converted PCAP file.

[0102] Result check module, through the file calculated MD5 value, and the MD5 value of the original file is compared, output test result.

[0103] Among them, can see, for the processing of traffic file, corresponding to the above content involves the protocol conversion and environmental simulation processing, here the test tool is targeted to configure two modules to distinguish processing, so, in the processing is relatively independent, more targeted and convenient.

[0104] The specific content can continue to refer to the following content:

[0105] 1. For PCAP conversion module

[0106] Can be based on the original input file, through the PCAP conversion module output different protocol PCAP message according to test case.

[0107] Among them, can support FTP, HTTP, HTTP / 2, SMTP, POP3, IMAP, IPV4 or IPV6 and other file transfer protocol.

[0108] As an example, can generate http-get method PCAP file, the generation process can refer to the diagram content of Figure 3 、 4 Among them, Figure 3 、 4 Respectively, the scene diagram of generating PCAP file of the application.

[0109] 2. For network simulation module

[0110] Can be based on fragroute, tcprewrite and other tools, according to the PCAP message generated by PCAP conversion module, modify the PCAP message under various network environments.

[0111] As another example, can generate TCP segment and fragmentation length of 160 message, such as Figure 5 The diagram content, among them, Figure 5 For a kind of scene diagram of TCP segment message of the application.

[0112] As shown in Figure 5 , the length of the original message is changed to TCP segment of 160 data.

[0113] 3. For the traffic playback module

[0114] The traffic playback can be based on tcpreplay or trex, etc. tools, according to the PCAP samples output by the network simulation module.

[0115] Among them, the corresponding traffic can be listened to for the device under test, and the data transmission samples in the traffic are restored.

[0116] 4. For the result checking module

[0117] The file restored by the traffic playback module is checked by MD5 value, and compared with the MD5 value calculated by the original sample, to judge whether the file restoration is accurate.

[0118] And the following shows a complete example.

[0119] Precondition: there is a sample file test.zip

[0120] 1. The test terminal connects the packet sending device and the device under test (DUT) through the paramiko module of python;

[0121] 2. Generate messages based on FTP, HTTP_GET, HTTP_POST, SMTP, IMAP or POP3 protocols through the PCAP conversion module;

[0122] 3. Generate network simulation configuration files, including various combination scenarios, and generate corresponding PCAP files;

[0123] Among them, the supported configuration parameters are:

[0124] delay first|last|random

[0125] drop first|last|random<prob-%>

[0126] dup first|last|random<prob-%>

[0127] echo <string>...

[0128] ip_chaff dup|opt| <ttl>

[0129] ip frag <size>[old | new]

[0130] ip_opt lsrr | ssrr <ptr> <ip-addr>...

[0131] ip_ttl <ttl>

[0132] ip_tos <tos>

[0133] order random|reverse

[0134] print

[0135] tcp_chaff cksum|null|paws|rexmit|seq|syn| <ttl>

[0136] tcp_opt mss |wscale <size>

[0137] tcp_seg <size>[old | new]

[0138] According to the parameters, different configurations can be generated, corresponding to different environment simulation processing:

[0139] As can be configured:

[0140] delay first 10

[0141] tcp_seg 1024

[0142] That is, the traffic scenario is constructed: the first packet delay is 10ms, and the TCP segment is 1024 PCAP data flow, such as Figure 6 The contents of the diagram, wherein, Figure 6 is a scene diagram for constructing a traffic scenario of the present application.

[0143] 4. The test terminal connects the packet sender through the paramiko module, reads the PCAP list generated according to the network model, and plays back according to the queue. After playback, the test terminal connects the device under test to check the results.

[0144] Among them, the restored result according to the identified traffic can be compared with the MD5 value of the measured sample.

[0145] After executing the use case, the initial environment and log record can be restored.

[0146] 5. After executing all test cases, output the test report to complete the output of the overall test results.

[0147] In summary, for the above scheme content, for the test requirement of the file transmission stability of the target file transmission link, after obtaining the sample traffic file, the present application converts it from the corresponding initial file transmission protocol to the target traffic file of different file transmission protocols, so as to improve the diversity of test cases. When testing the file transmission stability of the target file transmission link based on the target traffic file, the file transmission stability of the file transmission link can be tested more accurately. Under this test mechanism, it is obvious that not only the test accuracy can be improved, but also the execution efficiency and requirement coverage can be effectively improved, the false positives and omissions in the manual execution process can be reduced, so that the file transmission link can be accurately maintained and updated in the first time, and the stability can be improved.

[0148] The above is the introduction of the file transmission stability test method based on traffic restoration file provided by the present application. In order to better implement the file transmission stability test method based on traffic restoration file provided by the present application, the present application also provides a file transmission stability test device based on traffic restoration file from the functional module angle.
