technical field

The invention relates to the technical field of mobile communication, in particular to a performance test flow control technology of a mobile data service platform.

Background technique

With the continuous advancement of mobile communication technology, various mobile data services develop rapidly, the performance index of the mobile data service platform increases rapidly, and the payload of the mobile data service also increases accordingly. The mobile communication system includes a variety of mobile data service platforms, such as Multimedia Message Service Center (MMSC), Multimedia Message Gateway (Multimedia Message ServiceGateWay, MMS GW), Wireless Application Protocol Gateway (Wireless Application ProtocolGateWay, WAP GW), general download business platform, etc. Multimedia messages are commonly referred to as MMS, MMSC is commonly referred to as MMS center, and MMS GW is commonly referred to as MMS gateway. The payload of the multimedia message service is a multimedia message body, the payload of the WAP service is a WAP page, and the payload of the general download service is downloaded files, such as music files and game files.

When performing performance tests on various mobile data service platforms, the test tool simulates the external network elements of the mobile data service platform under test, and generates simulated traffic to pressurize the mobile data service platform under test, so as to detect the performance of the mobile data service platform under test Processing performance. Taking the performance test of the multimedia message center as an example, as shown in Figure 1, the test tool simulates the multimedia message sender, strictly speaking, the WAP GW to which the multimedia message sender belongs, and the multimedia message receiver, strictly speaking, the The WAP GW to which the multimedia message receiving end belongs detects the processing performance of the multimedia message center. The specific business process is that when the multimedia message sender sends a multimedia message, the multimedia message is first sent to the multimedia message center, and then forwarded by the multimedia message center to the multimedia message receiver. In this business process, the test tool performs protocol and business process simulation, statistical analysis of test results, etc., and can detect the performance of the multimedia message center according to the test results. In order to ensure the authority of the test, the test tools are usually based on the dedicated test tool hardware platform and the underlying software system, and carry out secondary development and implementation of the business state machine to ensure correct protocol simulation and business process simulation, so as to obtain accurate test results .

S＝1000*100*8/1024/1024≈800Mbps[1]

It can be seen that with the multiplication of multimedia message center performance indicators, the information volume of each multimedia message will increase significantly, and the processing performance of test tools will also increase accordingly. The bus bandwidth throughput rate of test tools is required to be above 1Gbps.

Detailed ways

The inventor found that the main reason for the rapid growth of the performance index of the mobile data service platform is that the information volume of the payload in various mobile data services increases rapidly, and the data transmission rate increases rapidly. Based on this, the embodiment of the present invention provides a mobile data service The platform performance test flow control scheme can reduce the requirements on the processing performance and bus bandwidth throughput of test tools, and on the basis of controlling the investment cost of mobile data service platform performance testing, the processing performance and bus bandwidth throughput of test tools can meet The performance index of the rapidly growing mobile data service platform under test.

In the mobile data service platform performance test system, the test results of the tested mobile data service platform are based on the forwarding capability of the mobile data service platform to the test message carrying the payload within a unit time, and other related test messages generated based on the business process. Such as reply or report, etc., its information volume is almost negligible relative to the information volume of the test message carrying the payload. Based on the authority of the test, other related test messages cannot be changed based on the requirements of protocol simulation and business process simulation. What can be changed is only the information amount of the payload in the test message carrying the payload. Based on the above analysis, the embodiment of the present invention firstly provides a mobile data service platform performance testing system and method, as shown in FIG. Flow control server 203, also referred to as proxy server (Proxy Server) in the embodiment of the present invention, wherein:

The test tool 201 generates a set number of test messages carrying payloads per unit time. For the convenience of distinguishing, the test messages are referred to as the first test message, and the payload in the first test message is referred to as the first payload. The test tool 201 sends each first test message to the simulation flow control server 203, and the number can be set arbitrarily;

The simulated traffic control server 203 generates a second test message after replacing the first payload in each first test message with a second payload, and sends the generated second test messages to the mobile data service platform 202 under test, The information volume of the second payload is greater than the information volume of the first payload, and both the first payload and the second payload can be called a message body, and together with the message header, they form a test message carrying a payload;

The mobile data service platform 202 under test receives each second test message, generates a third test message carrying the second payload according to the second test message, and forwards it back to the simulation flow control server 203;

The simulated flow control server 203 replaces the second payload in each third test message forwarded by the mobile data service platform 202 under test with the first payload and generates a fourth test message, and uses each generated fourth test message The message is returned to the testing tool 201;

The test tool 201 generates test results by counting the number of fourth test messages received per unit time, and analyzes the performance of the tested mobile data service platform 202 according to the test results.

Wherein, the difference between the information volume of the second payload and the first payload may be a set information volume difference; or, the ratio of the information volume of the second payload to the first payload may be a set scaling factor, And the scale factor is greater than 1.

In this test process, other relevant test messages generated based on the business process are transparently transmitted by the simulated traffic control server 203 .

Figure 2 is an example of a simulated flow control server. When the number of test messages carrying payloads sent by the test tool is large, in order to improve the processing performance of the test tool and the throughput of the bus bandwidth, in the test system Configure multiple simulation flow control servers for parallel processing, and each simulation flow control server is responsible for processing a certain number of test messages. The simulated flow control server adopted in the embodiment of the present invention is a common server in the prior art, and its hardware, such as CPU, internal memory, high-speed gigabit network card, etc., can be freely customized in terms of performance configuration and quantity. The price of the hardware board is greatly reduced.

Based on the mobile data service platform performance test system in Figure 2, the mobile data service platform performance test method is described in detail. The test tool 201 simulates the sending end 2011 and the receiving end 2012 through a state machine control mode, specifically including:

First, the test tool 201 simulates the uplink business process of the sending end 2011 sending a test message, and the sending end 2011 generates a set number of first test messages per unit time, and sends each test message to the simulation flow control server 203, and the simulation flow After the control server 203 processes each first test message, it generates a second test message and sends it to the mobile data service platform 202 under test; in this process, the first test message sent by the sending end 2011 to the simulation traffic control server 203 includes The message header related to the protocol carried and the first payload with a small amount of information; the simulation flow control server 203 replaces the first payload in each first test message with a second payload that meets the test requirements, specifically The replacement method adds a set amount of information to the first payload, such as 100Kbytes, or multiplies the amount of information of the first payload by a set scale factor, such as a scale factor of 100, etc., and then replaces the message body and carries the second The second test message of the payload includes a second payload with a larger amount of information and the same message header as the first test message;

The mobile data service platform 202 under test generates a third test message according to the received second test messages, and then the mobile data service platform 202 under test triggers the downlink business process of receiving the test message at the receiving end 2012, and carries the second payload of the second test message. The three test messages are forwarded back to the simulation flow control server 203, and the simulation flow control server 203 generates the fourth test message after processing each third test message and returns to the receiver 2012 simulated by the test tool 201; in this process, the simulation flow control server 203 Replace the second payload with a large amount of information in each third test message with the first payload with a small amount of information, and the method of replacing the second payload with the first payload is the same as that in the uplink service flow The method corresponds to the specific replacement method by subtracting the set information amount from the second payload, such as 100Kbytes, or dividing the information amount of the second payload by the set scaling factor, such as the scaling factor is 100, etc.;

Finally, the test tool 201 generates a test result by counting the number of fourth test messages received per unit time, and analyzes the performance of the mobile data service platform 202 under test according to the test result.

Throughout the uplink and downlink business processes, the dedicated test tools still carry out protocol and business process simulation, statistical analysis of test results, etc., to ensure the accuracy and authority of the test results. Between mobile data service platforms 202, when sending a test message to the mobile data service platform 202 under test, the first test message bearing the first payload is replaced with the second test message bearing the second payload; 201 When returning the test message, replace the third test message carrying the second payload with the fourth test message carrying the first payload. Using this method reduces the consumption of processing resources and bus bandwidth by the hardware processing board, greatly reduces the requirements for the test performance and bus bandwidth throughput of the hardware processing board, and reduces the test cost; at the same time, the test process also meets the requirements Test the performance indicators of the mobile data service platform to ensure the accuracy of the test.

Adopting the solution provided by the embodiment of the present invention can greatly reduce the requirements on the processing performance of the test tool and the throughput rate of the bus bandwidth on the basis of satisfying the performance index of the mobile data service platform to be tested, thereby reducing the test cost and effectively ensuring the accuracy of the test work.

As shown in Figure 7, it is a schematic diagram of the test message interaction based on the WAP1.x protocol browsing service in the WAP service, wherein the WAP browser is a WAP1.x browser, and the WAP1.x browser requests the WEB server to browse a WAP page, which corresponds to a The testing process, specifically includes:

S701, the test tool simulates the WAP1.x browser to generate a wireless session protocol (Wireless Session Protocol, WSP) browsing request message WSP GET Request, and sends it to the WAP GW via the server 1, requesting to browse the WAP page;

S702, after the WAP GW receives the WSP GET Request, it generates a Hypertext Transfer Protocol (HyperText Transfer Protocol, HTTP) browsing request message HTTP GET Request, and sends it to the WEB server via the server 2;

S703, after the WEB server receives the HTTP GET Request, the WAP page to be sent to the WAP1.x browser, that is, the first payload is encapsulated in the hypertext transfer protocol browsing response message HTTPGET Response, and the HTTP GET Response is the first test message, the HTTP GETResponse is first sent to server 2, and server 2 generates a new HTTP GET Response after replacing the first payload in the HTTP GET Response with the second payload, and the new HTTP GET Response is the second test message , Server 2 sends the new HTTPGET Response to the WAP GW under test;

S704. After receiving the HTTP GET Response, the tested WAP GW generates a wireless session protocol response message WSP GET Response, the WSP GET Response encapsulates the second payload extracted from the HTTP GET Response, and the WSP GET Response is the third test message , the WSP GETResponse is first sent to server 1, and server 1 replaces the second payload in the WSP GET Response with the first payload and generates a new WSP GET Response. The new WSPGET Response is the generated fourth test message, server 1 returns the new WSP GET Response to the WAP1.x browser;

After the WAP1.x browser receives the WSP GET Response, the test tool believes that the tested WAPGW successfully forwards the first payload.

In this test process, the simulated flow control server replaces the payload of HTTP GET Response and WSP GETResponse, and does not process other test messages but transparently transmits them.

S801, the test tool simulates the WAP2.0 browser to generate a hypertext transfer protocol browsing request message HTTP GET Request, and sends it to the WAP GW via the server 1, requesting to browse the WAP page;

S802. After receiving the HTTP GET Request, the WAP GW forwards the HTTP GET Request to the WEB server via server 2;

S803, after the WEB server receives the HTTP GET Request, the WAP page to be sent to the WAP2.0 browser, that is, the first payload is encapsulated in the hypertext transfer protocol browsing response message HTTPGET Response, and the HTTP GET Response is the first test message, the HTTP GETResponse is first sent to server 2, and server 2 generates a new HTTP GET Response after replacing the first payload in the HTTP GET Response with the second payload, and the new HTTP GET Response is the second test message , Server 2 sends the new HTTPGET Response to the WAP GW under test;

S804. After receiving the HTTP GET Response, the tested WAP GW directly forwards it. The HTTP GET Response carries the second payload, which is the third test message. The HTTP GET Response is first sent to server 1, and server 1 sends the HTTP GET Response A new HTTP GET Response is generated after replacing the second payload in the first payload, and the new HTTP GETResponse is the generated fourth test message, and server 1 returns the new HTTP GET Response to the WAP2.0 browser ;

After the WAP2.0 browser receives the HTTP GET Response, the test tool believes that the tested WAPGW successfully forwards the first payload.

In this test process, the simulated flow control server replaces the payload of the two HTTP GET Response, and does not process other test messages but transparently transmits them.

In the process of performance testing of WAP GW, the simulated traffic control server only replaces the test message carrying the payload, and when sending the test message to the WAP GW under test, the first part of the test message with a small amount of information is replaced. A payload is replaced with a second payload with a large amount of information; when the test message is sent to the test tool, the second payload with a large amount of information in the test message is replaced with a first payload with a small amount of information ; while other test messages in the test process are not processed, only transparently transmitted.

In the following, the specific realization principle and method of performing payload replacement by the simulated flow control server on the test message carrying the payload in the embodiment of the present invention will be described in detail. In the embodiment of the present invention, the simulated flow control server adopts a realization method combining multiple concurrent main processes and multiple concurrent sub-threads, and its operation model is shown in FIG. 11 . The main process, called the TOP process, continuously listens to the new test process from the client, and derives a sub-thread for each test process, called the subThread thread, which is responsible for processing all the tests involved in each test process information. The client here is a test tool, and the destination is the mobile data service platform to be tested, and multiple TOP processes can be run simultaneously in a simulated traffic control server, which provides great flexibility for the deployment of TOP processes.

The implementation principle of the TOP process is introduced in detail below. As shown in Figure 12, the processing flow of the TOP process includes:

S1201～S1202, initialize the client-oriented socket Socket information, including IP address, port number Port, etc., and create Socket;

S1203, the TOP process continuously monitors the test message of the client on the designated listening port through the Socket, and judges whether a new test process is coming;

For example, in the MOMT business scenario in the multimedia message service, the new test process is considered to be coming when the MM1_Submit.Req message is monitored; in the WAP1.x service, the new test process is considered to be coming when the WSP GET Request message is heard;

S1204. If a new client test process arrives in the Socket, the test message of the test process arrives at the Socket;

S1205. Determine whether the test message is received correctly, if yes, execute S1206, if not, execute S1207;

S1206, generating a subThread thread for subsequent processing, the test message of the client is used as a parameter of the subThread function, and the parameter is represented by SrcSock;

S1207. Considering that blocking occurs, and return to execute S1205.

Due to the arrival of many concurrent test messages, multiple subThread threads are running simultaneously in the simulated flow control server.

The subThread thread is derived from the TOP process and is used to process the test message submitted by the client. The implementation principle of the subThread thread is introduced in detail below. As shown in Figure 13, the processing flow of the subThread thread includes:

S1301～S1304, use the parameter SrcSock corresponding to the test message to obtain the information of the client Socket, including IP address, port number Port, etc., and obtain the parameter information of creating the destination Socket, that is, DstSock through corresponding substitution conversion, and create DstSock to connect to destination;

S1305. Select different processing functions to replace the effective load according to the different test message carrying protocols to be processed, for example, use the HttpProxy function for the test message carried by the HTTP protocol; use the SmtpProxy function for the test message carried by the SMTP protocol ;Other agreements will not be repeated;

S1306～S1307, when carrying on the HTTP protocol, use two different sub-threads to process the bidirectional information flow of the same Socket, first derive a new sub-thread to execute the processing of the HttpProxy function, use SrcSock and DstSock as parameters, and then itself Also call the HttpProxy function for processing, using the reverse parameter order, that is, using DstSock and SrcSock as parameters; or,

S1308～S1309, when the SMTP protocol is carried, two different sub-threads are also used to process the bidirectional information flow of the same Socket. First, a new sub-thread is derived to perform the processing of the SmtpProxy function, using SrcSock and DstSock as parameters, and then It also calls the SmtpProxy function for processing, using the reverse parameter order, that is, using DstSock and SrcSock as parameters.

The two-way information flow of the same Socket is processed by two dedicated sub-threads, as shown in Figure 14. This design implementation method has exquisite design ideas, simple processing methods, and high reusability.

In the multimedia message service, the MO, MT and AO messages are carried on the HTTP protocol, and the FO and FT messages are carried on the SMTP protocol; in the WAP service, the WAP page is carried on the HTTP protocol; the protocols carried in other mobile data services There are also corresponding interface specifications. For each test message that the present invention relates to, the HttpProxy function carries out the effective load that is the replacement of the multimedia message body for the MM1_Submit.Req, MM1_Retrieve.Res and MM7_Deliver.Req messages, and the effective load for the HTTP GETResponse message is the replacement of the WAP page; the SmtpProxy function is for The MM4_Forward.Req message replaces the payload, that is, the multimedia message body, and does not perform any processing on other test messages involved in the test process, but only transparently transmits them.

The function for performing payload replacement in the test message is described in detail below, taking the HttpProxy function for the HTTP protocol and the SmtpProxy function for the SMTP protocol as examples.

As shown in Figure 15, it is a flow chart of the HttpProxy function, the parameters are SrcSock and DstSock, for the test message carried by the HTTP protocol, in the same Socket, for replacing the first payload with the second payload and the second payload Replacing the payload with the first payload is also applicable, but the order of calling parameters is different.

S1502. Determine whether the read byte length is empty, if not, execute S1503, and if yes, execute S1508;

S1503. According to the offset and value of "Content-Length" searched in the message header of the test message, determine the message type to which the test message belongs, such as MM1_Submit.req, so as to determine whether the first payload is carried, if yes , execute S1504, if not, execute S1507;

S1504, in the test message, determine its starting position by searching the starting position flag of the first payload, for example, the starting position of the multimedia message body can be found through the flag JFIF of the JPEG image;

S1505. Generate a second test message by replacing the first payload in the test message carrying the first payload with the second payload;

S1506. Return to the destination end through DstSock after performing payload replacement, and return to execute S1501;

S1507. Directly forward to the destination through DstSock without any processing, return to execute S1501;

S1508. Close the SrcSock and DstSock, and end the process.

As shown in Figure 16, it is a flow chart of the SmtpProxy function. For the test message carried by the SMTP protocol, the parameters are SrcSock and DstSock. In the same Socket, for replacing the first payload with the second payload and the second payload It is also applicable to replace the effective load with the first effective load, but the order of calling parameters is different. In this embodiment, the second effective load is replaced with the first effective load as an example for illustration. First call DstSock and then call SrcSock, which specifically includes the following steps:

S1601, receiving the test message of the destination, the reception of the test message is realized by sequentially reading a certain length of bytes from the DstSock into the cache;

S1602. Determine whether the read byte length is empty, if not, execute S1603, and if yes, execute S1609;

S1603. Determine whether the test message is a link establishment message according to the message header of the test message, if yes, execute S1608, and if not, execute S1604;

The SmtpProxy function checks whether there is link establishment identification information in the received test message, such as "220", "HELO", "250", "354", "MAIL FROM", "RCPT TO", "DATA", etc. , if it is, it is judged that the test message is the SMTP link building message;

S1604. The test message is a message carrying the actual business process. According to the message type "X-Mms-Message-Type" searched in the message header of the test message, the message type of the actual business process is judged by its value, such as MM4_Forward .Req, thereby determining whether the second payload is carried, if yes, execute S1605, if not, execute S1608;

S1605. Determine the starting position of the second payload by searching for a specific BASE64 code in the message body, such as the first few bytes of the BASE64 code of a specific picture;

S1606. Replace the second payload in the third test message with the first payload, and generate a fourth test message;

S1607. Return to the client through SrcSock after performing payload replacement, and return to execute S1601;
