The protocol data simulation in the present embodiment includes:
and S1, capturing the original protocol data set from the network by using a pre-constructed packet capturing tool according to the protocol data acquisition request.
The invention mainly aims to simulate protocol data, in particular to simulate millions of protocol data, so as to conveniently use the simulated protocol data to carry out performance test, gateway test and the like.
Preferably, the protocol data acquisition request may be an instruction, for example, a click key related to the protocol data acquisition request is pre-designed in a graphical interface, and a user only needs to click the click key related to the protocol data acquisition request to generate the instruction of the protocol data acquisition request.
The packet capturing tool is a tool for sending a request to a network server and acquiring a result of the request. The invention can use the packet capturing tools such as wireshark, glidder, Httpwatch and the like to achieve the purpose of capturing and obtaining the original protocol data set from the network.
In particular, the original protocol data set may be an original gateway address of the user. Further, the original protocol data set is stored in a pcap file storage format, the pcap file storage format includes a file header, a data header and data content, wherein the file header, the data header and the data content all occupy a certain number of bytes, for example, the file header occupies 1-8 bytes, and the data header occupies 9-16 bytes.
And S2, according to a preset quintuple judgment method, carrying out data division on the original protocol data set to obtain a standard protocol data set.
In detail, the data partitioning includes: cleaning the original protocol data set, carrying out proportion configuration on the cleaned original protocol data set according to a preset protocol type proportion to obtain a primary protocol data set, judging whether quintuple of primary protocol data in the primary protocol data set is the same according to the quintuple judging method, placing the same primary protocol data in a preset same data stream, and summarizing the data stream to obtain a standard protocol data set.
Furthermore, the cleaning is to filter the uplink and downlink data in the original protocol data and retain the quintuple information of the original protocol data, so that the protocol data can be more truly met. The quintuple information includes: the source IP address, source port, destination IP address, destination port, and transport layer protocol five sets of information, such as: 192.168.1.110000 TCP 121.14.88.7680 is protocol data only including quintuple information, and a terminal with a source IP address of 192.168.1.1 is connected with a terminal with a destination IP address of 121.14.88.76 and a destination port of 80 by using a TCP protocol through a source port 10000.
In detail, the implementation steps of the proportional configuration are shown in fig. 2, and include the following steps:
and S21, extracting all protocol types from the protocol type proportion to obtain a required protocol type set, wherein the required protocol type set is in the cleaned original protocol data set.
And S22, removing the protocol type data different from the required protocol type set to obtain a required protocol data set.

In detail, the character string conversion includes: and carrying out binary conversion on the conversion protocol data set, and carrying out character string conversion on the conversion protocol data set subjected to the binary conversion according to a pre-constructed character string conversion code to obtain an analog protocol data set.
Preferably, the protocol data is presented in decimal form, such as 192.168.1.110000, but because the protocol data involved in the present invention is huge in size, reaching the millions, it is preferable to convert the protocol data in decimal form into protocol data in hexadecimal form, i.e. to make the said binary conversion.
Preferably, the protocol data are all in integer data format (int), and the pre-constructed character string conversion code of the invention is run to convert the data format stored in integer (int) in the standard protocol data set into character string format (string), so that the storage pressure of data storage can be reduced, because the byte number of the character string is smaller than the byte number of the integer.

Preferably, the performance test includes, but is not limited to, a gateway test, a user traffic test, a server and other background performance tests.
The byte group conversion operation is to convert the encryption protocol data set into a byte network transmission form, so that data interaction of backstage such as a server is facilitated. The packaging is to uniformly package a plurality of groups of encryption protocol tuples, so that faster data receiving of backstage such as a server is accelerated.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.

cleaning the original protocol data set, and carrying out proportion configuration on the cleaned original protocol data set according to a protocol type proportion configured in advance to obtain a primary protocol data set;
and judging whether quintuple information among each primary protocol data in the primary protocol data set is the same or not according to the quintuple judging method, placing the same primary protocol data in the preset same data stream, and summarizing the data stream to obtain a standard protocol data set.
5. The method of protocol data simulation of claim 4, wherein the scaling configuration comprises:
extracting all protocol types from the protocol type proportion to obtain a required protocol type set;
removing protocol type data different from the required protocol type set from the cleaned original protocol data set to obtain a required protocol data set;
and dividing the protocol type proportion of the required protocol data set according to the protocol type proportion, and completing the proportion configuration to obtain a primary protocol data set.
6. The method of protocol data emulation according to claim 4, wherein the five-tuple information comprises: source IP address, source port, destination IP address, destination port, and transport layer protocol.
7. The method of protocol data emulation according to claim 1, wherein the string conversion comprises:
carrying out binary conversion on the conversion protocol data set;
and according to a pre-constructed character string conversion code, performing character string conversion on the conversion protocol data set which completes the binary conversion to obtain the simulation protocol data set.
8. An apparatus for protocol data emulation, comprising:
at least one processor; and the number of the first and second groups,
a memory communicatively coupled to the at least one processor; wherein the content of the first and second substances,
the memory stores instructions executable by the at least one processor to enable the at least one processor to perform a method of protocol data simulation as claimed in any one of claims 1 to 7.
9. A computer-readable storage medium, in which a computer program is stored which, when being executed by a processor, carries out the method of protocol data simulation according to one of claims 1 to 7.
