Example one
Fig. 1 is a schematic application environment diagram of a pressure testing method for an on-demand distribution system according to an embodiment of the present invention.
Referring to fig. 1, an application environment of the on-demand distribution system pressure testing method includes an on-demand distribution system pressure testing apparatus 10, a client 2, an on-demand distribution system 3, and an on-demand service node 4. The on-demand distribution system pressure testing device 10 is in communication connection with the client 2 and the on-demand distribution system 3, the client 2 is also in communication connection with the on-demand distribution system 3 and the on-demand service node 4, and the on-demand distribution system 3 is also in communication connection with the on-demand service node 4.
The pressure testing device 10 of the on-demand distribution system performs pressure testing on the on-demand distribution system 3 through the client 2 to obtain a pressure testing index of the on-demand distribution system 3.
The client 2 is used to provide on-demand services (e.g. video-on-demand services) to individual users. In this embodiment, the client 2 may be a personal cloud disk, such as a guest-playing cloud. The number of the clients 2 is multiple. The number of the clients 2 can be set according to the test requirements. For example, in one embodiment, the number of clients 2 may be one hundred thousand.
The on-demand distribution system 3 is used for deploying the pressure measurement file to the on-demand service node 4 according to the scheduling request of the client 2.
The on-demand service node 4 is used to provide on-demand data (e.g., video data). The client 2 obtains the on-demand data from the on-demand service node 4. The number of the on-demand service nodes 4 is also multiple.
Example two
Fig. 2 is a flowchart of a pressure testing method for an on-demand distribution system according to an embodiment of the present invention.
Referring to fig. 2, the pressure testing method for the on-demand distribution system specifically includes the following steps:
step 201, the pressure testing device 10 of the on-demand distribution system issues a pressure policy to the client 2, where the pressure policy includes a pressure measurement file and a pressure measurement frequency.
In this embodiment, the stress test for the on-demand distribution system 3 includes a single file stress test, a fixed file list stress test, and a dynamic update file list stress test.
If the unicast distribution system 3 is subjected to a single file pressure test, the pressure test file is a single file.
If the fixed file list pressure test is performed on the multicast distribution system 3, the pressure test file is a file in the fixed file list. For example, a file can be randomly selected from a fixed file list as a compression test file; alternatively, one file may be selected from the fixed file list in a predetermined order as the compression file.
If the pressure test of the dynamic update file list is performed on the multicast distribution system 3, the pressure test file is a file in the dynamic file list. For example, the dynamic file list may be updated according to a preset frequency (e.g., once per hour), and a file is randomly selected from the dynamic file list as a pressure measurement file; or selecting one file from the dynamic file list as a pressure measurement file according to a preset sequence.
The pressure test frequency is a frequency at which the on-demand distribution system 3 is pressure tested. The frequency of pressure measurements may be set as desired, for example, every 20 seconds, every minute, every 10 minutes.
Step 202, the client 2 sends a scheduling request for the pressure measurement file to the on-demand distribution system 3 according to the pressure measurement frequency.
If the single file pressure test is performed on the on-demand distribution system 3, the client 2 sends a scheduling request for a single file to the on-demand distribution system 3 according to the pressure test frequency. For example, client 2 sends a scheduling request to the on-demand distribution system 3 every 20s, each time requesting the same file.
If the on-demand distribution system 3 is subjected to the pressure test of the fixed file list, the client 2 sends a scheduling request to the on-demand distribution system 3 according to the pressure test frequency, and requests one file in the fixed list each time. For example, the client 2 sends a scheduling request to the on-demand distribution system 3 every 20s, each time requesting a randomly chosen file from the fixed list.
If the on-demand distribution system 3 is subjected to a pressure test for dynamically updating the file list, the client 2 sends a scheduling request to the on-demand distribution system 3 according to the pressure test frequency, and requests one file in the dynamic file list each time. For example, the client 2 sends a scheduling request to the on-demand distribution system 3 every 20s, each time requesting a randomly selected file from the dynamic file list.
Step 203, the on-demand distribution system 3 deploys the pressure measurement file to the on-demand service node 4 according to the scheduling request, and returns the on-demand service node 4 deployed with the pressure measurement file to the client 2.
The on-demand distribution system 3 counts the scheduling request times of the pressure measurement files, obtains the heat of the pressure measurement files according to the scheduling request times of the pressure measurement files, and determines the file deployment number of the pressure measurement files according to the heat of the pressure measurement files.
And if the dispatching request times of the pressure measurement file are more, the heat degree of the pressure measurement file is high. Otherwise, if the scheduling request frequency of the pressure measurement file is less, the heat of the pressure measurement file is low. For example, a pressure measurement file with the scheduling request number greater than or equal to 10000 in a preset time (e.g., 10 minutes) may be defined as a high-heat pressure measurement file, a pressure measurement file with the scheduling request number less than 10000 and greater than or equal to 1000 in the preset time may be defined as a medium-heat pressure measurement file, and a pressure measurement file with the scheduling request number less than 1000 in the preset time may be defined as a low-heat pressure measurement file.
In this embodiment, each scheduling request corresponds to one regional operator. Each on-demand service node also corresponds to a regional carrier. On-demand distribution system 3 also determines the regional operator distribution of the pressure files based on their heat.
A regional operator is a particular network operator for a particular geographic region. The regions may include six geographical regions "east China", "North China", "south China", "northeast", "northwest" and "southwest". The operators can comprise three network operators of 'telecom', 'Unicom' and 'mobile'. Thus, the regional operators may include 18 regional operators, including eastern China telecom, eastern China Union, eastern China Mobile, southern China telecom, southern China Union, southern China Mobile … … southwest China telecom, southwest China Union, and southwest China Mobile.
After receiving the on-demand service node 4 that deploys the pressure measurement file and is returned by the on-demand distribution system 3, the client 2 may send a data request for the pressure measurement file to the on-demand service node 4 (i.e., the on-demand service node 4 that deploys the pressure measurement file), and receive playable data (e.g., video data) of the pressure measurement file and is returned by the on-demand service node 4.
Step 204, the on-demand distribution system pressure testing device 10 obtains a pressure testing index of the on-demand distribution system 3.
The pressure measurement index of the on-demand distribution system 3 refers to the performance index of the on-demand distribution system 3 executing the deployment of the pressure measurement file to the on-demand service node 4 according to the scheduling request and returning the on-demand service node 4 deployed with the pressure measurement file to the client 2.
In this embodiment, the pressure measurement indexes include a file distribution speed, a file deployment number, and a scheduling response time.
The file distribution speed is the speed from when a scheduling request is received from the on-demand distribution system 3 to when the pressure measurement file is deployed to the on-demand service node 4. The file distribution speed may be an average file distribution speed of the on-demand distribution system 3 over a certain time.
The number of file deployment copies is the number of copies of the requested pressure measurement file that the on-demand distribution system 3 deploys to the on-demand service node 4.
The schedule response time is the time from when the schedule request is received from on-demand distribution system 3 to when on-demand service node 4 deploying the pressure measurement file is returned to client 2.
On-demand distribution system 3 may directly record the pressure measurement indicator, such as a log file recorded at on-demand distribution system 3.
Or, the on-demand distribution system 3 may record file deployment information of the pressure measurement file, and the pressure test device 10 of the on-demand distribution system acquires the file deployment information and acquires the pressure measurement index according to the file deployment information. For example, the on-demand distribution system 3 records each on-demand service node 4 that deploys the pressure measurement file, and the on-demand distribution system pressure test device 10 counts the number of file deployments of the pressure measurement file according to each on-demand service node 4 that deploys the pressure measurement file. For another example, on-demand distribution system 3 records the time when on-demand distribution system 3 receives the scheduling request and the time until on-demand service node 4 that deploys the pressure measurement file returns to client 2, and on-demand distribution system pressure testing apparatus 10 calculates the scheduling response time according to the time when on-demand distribution system 3 receives the scheduling request and the time until on-demand service node 4 that deploys the pressure measurement file returns to client 2.
The on-demand distribution system pressure testing device 10 may send a pressure measurement data request to the on-demand distribution system 3, requesting the pressure measurement index or the file deployment information. And after receiving the pressure measurement data request, the on-demand distribution system 3 returns the pressure measurement indexes or the file deployment information to the pressure testing device 10 of the on-demand distribution system. Or, the on-demand distribution system 3 may actively send the pressure measurement index or the file deployment information to the on-demand distribution system pressure testing device 10 according to a preset period, and the on-demand distribution system pressure testing device 10 receives the pressure measurement index or the file deployment information periodically sent by the on-demand distribution system 3.
Step 205, the on-demand distribution system pressure testing device 10 determines whether the on-demand distribution system 3 meets the system requirements according to the pressure measurement index.
It may be determined whether the scheduling response time is less than or equal to a preset time, and if the scheduling response time is less than or equal to the preset time, the on-demand distribution system 3 meets the system requirements. Otherwise, if the scheduling response time is longer than the preset time, the on-demand distribution system 3 does not meet the system requirements.
Or, it may be determined whether the number of file deployment copies is greater than or equal to a preset number of deployment copies, and if the number of file deployment copies is greater than or equal to the preset number of deployment copies, the on-demand distribution system 3 meets the system requirements. Otherwise, if the number of file deployment copies is smaller than the preset number of deployment copies, the on-demand distribution system 3 does not meet the system requirements. And the preset number of deployment copies is determined according to the heat of the pressure measurement file.
Particularly, it may be determined whether the number of file deployment copies of the pressure measurement file in the preset regional operator is greater than or equal to a preset number of deployment copies, and if the number of file deployment copies of the pressure measurement file in the preset regional operator is greater than or equal to the preset number of deployment copies, the on-demand distribution system 3 meets the system requirements. Otherwise, if the number of file deployment copies of the pressure measurement file in the preset regional operator is smaller than the preset number of deployment copies, the on-demand distribution system 3 does not meet the system requirements. And determining the preset deployment number according to the popularity of the pressure measurement file in the preset operator. The judgment of the number of file deployment copies of the pressure-measured file in the preset regional operator is to determine whether the on-demand distribution system 3 has the regional operator hotspot judgment capability, and whether the file deployment can be performed according to the regional operator popularity of the pressure-measured file. Only if the on-demand distribution system 3 deploys a sufficient number of files in the regional operator corresponding to the pressure-measured file, the corresponding scheduling request can be satisfied.
Or, it may be determined whether the file distribution speed is greater than or equal to a preset speed, and if the file distribution speed is greater than or equal to the preset speed, the on-demand distribution system 3 meets the system requirement. Otherwise, if the file distribution speed is lower than the preset speed, the on-demand distribution system 3 does not meet the system requirement.
In order to improve the accuracy of pressure measurement, in this embodiment, determining whether the on-demand distribution system 3 meets the system requirement according to the pressure measurement indicator may include:
(1) for single file pressure measurement, judging whether the file distribution speed is less than or equal to a preset time, if so, enabling the on-demand distribution system 3 to meet the system requirement; otherwise, if the file distribution speed is greater than the preset time, the on-demand distribution system 3 does not meet the system requirements. When a single file is compressed, all clients 2 compress the same file. If the request of the same file falls on a specific on-demand service node, the load of the on-demand service node is high, and other on-demand service nodes without requests are idle. If the scheduling response time of the on-demand distribution system 3 to the single file is longer than the preset time, it indicates that the on-demand distribution system 3 cannot optimize the hot spot processing, and the problem of single-point overheating exists, so that the system requirements are not met.
(2) For the fixed file array pressure measurement, judging whether the file deployment number is greater than or equal to a preset deployment number, if so, enabling the on-demand distribution system 3 to meet the system requirement; otherwise, if the number of file deployment copies is smaller than the preset number of deployment copies, the on-demand distribution system 3 does not meet the system requirements. For example, a pressure measurement file with the scheduling request number greater than or equal to 10000 within a preset time (e.g., 10 minutes) is defined as a high-heat pressure measurement file, and if the file deployment number of the high-heat pressure measurement file is less than or equal to 10000, the on-demand distribution system 3 does not meet the system requirement. Fixed file column pressure measurement scenarios the throughput capability of the on-demand distribution system 3 is primarily measured without new files added.
(3) For the dynamic update file array pressure measurement, judging whether the file distribution speed is greater than or equal to a preset speed, if so, the on-demand distribution system 3 meets the system requirement; otherwise, if the file distribution speed is lower than the preset speed, the on-demand distribution system 3 does not meet the system requirement. The dynamic updating of the file array pressure measurement scene is more suitable for the actual service use of the on-demand distribution system 3, and the file distribution speed is the most important pressure measurement index. Therefore, it can be determined whether the file distribution speed is less than or equal to the preset speed during dynamic update file array pressure measurement, and if the file distribution speed is less than or equal to the preset speed, it indicates that the on-demand distribution system 3 cannot timely deploy the pressure measurement file, so that the system requirements are not met.
In the pressure test method for the on-demand distribution system of the second embodiment, the pressure test device 10 of the on-demand distribution system issues a pressure strategy to the client 2; the client 2 sends a scheduling request for the pressure measurement file to the on-demand distribution system 3 according to the pressure measurement frequency; the on-demand distribution system 3 deploys the pressure measurement file to an on-demand service node 4 according to the scheduling request, and returns the on-demand service node 4 deployed with the pressure measurement file to the client 2; the pressure testing device 10 of the on-demand distribution system obtains a pressure testing index of the on-demand distribution system 3; and the pressure testing device 10 of the on-demand distribution system judges whether the on-demand distribution system 3 meets the system requirements or not according to the pressure testing index. The second pressure testing method for the on-demand distribution system in the embodiment can be used for simulating an on-demand request by using the client and carrying out pressure testing on the on-demand distribution system.
EXAMPLE III
Fig. 3 is a flowchart of a pressure testing method for an on-demand distribution system according to an embodiment of the present invention. The pressure testing method of the on-demand distribution system is applied to the pressure testing device 10 of the on-demand distribution system.
Referring to fig. 3, the pressure testing method for the on-demand distribution system specifically includes the following steps:
step 301, issuing a pressure policy to the client 2, where the pressure policy includes a pressure measurement file and a pressure measurement frequency, so that the client 2 sends a scheduling request for the pressure measurement file to the on-demand distribution system 3 according to the pressure measurement frequency, the on-demand distribution system 3 deploys the pressure measurement file to the on-demand service node 4 according to the scheduling request, and the on-demand service node 4 deploying the pressure measurement file returns to the client 2.
In this embodiment, the stress test for the on-demand distribution system 3 includes a single file stress test, a fixed file list stress test, and a dynamic update file list stress test.
If the unicast distribution system 3 is subjected to a single file pressure test, the pressure test file is a single file.
If the fixed file list pressure test is performed on the multicast distribution system 3, the pressure test file is a file in the fixed file list. For example, a file can be randomly selected from a fixed file list as a compression test file; alternatively, one file may be selected from the fixed file list in a predetermined order as the compression file.
If the pressure test of the dynamic update file list is performed on the multicast distribution system 3, the pressure test file is a file in the dynamic file list. For example, the dynamic file list may be updated according to a preset frequency (e.g., once per hour), and a file is randomly selected from the dynamic file list as a pressure measurement file; or selecting one file from the dynamic file list as a pressure measurement file according to a preset sequence.
The pressure test frequency is a frequency at which the on-demand distribution system 3 is pressure tested. The frequency of pressure measurements may be set as desired, for example, every 20 seconds, every minute, every 10 minutes.
And the client 2 sends a scheduling request for the pressure measurement file to the on-demand distribution system 3 according to the pressure measurement frequency.
If the single file pressure test is performed on the on-demand distribution system 3, the client 2 sends a scheduling request for a single file to the on-demand distribution system 3 according to the pressure test frequency. For example, client 2 sends a scheduling request to the on-demand distribution system 3 every 20s, each time requesting the same file.
If the on-demand distribution system 3 is subjected to the pressure test of the fixed file list, the client 2 sends a scheduling request to the on-demand distribution system 3 according to the pressure test frequency, and requests one file in the fixed list each time. For example, the client 2 sends a scheduling request to the on-demand distribution system 3 every 20s, each time requesting a randomly chosen file from the fixed list.
If the on-demand distribution system 3 is subjected to a pressure test for dynamically updating the file list, the client 2 sends a scheduling request to the on-demand distribution system 3 according to the pressure test frequency, and requests one file in the dynamic file list each time. For example, the client 2 sends a scheduling request to the on-demand distribution system 3 every 20s, each time requesting a randomly selected file from the dynamic file list.
And the on-demand distribution system 3 deploys the pressure measurement file to the on-demand service node 4 according to the scheduling request, and returns the on-demand service node 4 deployed with the pressure measurement file to the client 2.
The on-demand distribution system 3 counts the scheduling request times of the pressure measurement files, obtains the heat of the pressure measurement files according to the scheduling request times of the pressure measurement files, and determines the file deployment number of the pressure measurement files according to the heat of the pressure measurement files.
And if the dispatching request times of the pressure measurement file are more, the heat degree of the pressure measurement file is high. Otherwise, if the scheduling request frequency of the pressure measurement file is less, the heat of the pressure measurement file is low. For example, a pressure measurement file with the scheduling request number greater than or equal to 10000 in a preset time (e.g., 10 minutes) may be defined as a high-heat pressure measurement file, a pressure measurement file with the scheduling request number less than 10000 and greater than or equal to 1000 in the preset time may be defined as a medium-heat pressure measurement file, and a pressure measurement file with the scheduling request number less than 1000 in the preset time may be defined as a low-heat pressure measurement file.
In this embodiment, each scheduling request corresponds to one regional operator. Each on-demand service node also corresponds to a regional carrier. On-demand distribution system 3 also determines the regional operator distribution of the pressure files based on their heat.
A regional operator is a particular network operator for a particular geographic region. The regions may include six geographical regions "east China", "North China", "south China", "northeast", "northwest" and "southwest". The operators can comprise three network operators of 'telecom', 'Unicom' and 'mobile'. Thus, the regional operators may include 18 regional operators, including eastern China telecom, eastern China Union, eastern China Mobile, southern China telecom, southern China Union, southern China Mobile … … southwest China telecom, southwest China Union, and southwest China Mobile.
After receiving the on-demand service node 4 that deploys the pressure measurement file and is returned by the on-demand distribution system 3, the client 2 may send a data request for the pressure measurement file to the on-demand service node 4 (i.e., the on-demand service node 4 that deploys the pressure measurement file), and receive playable data (e.g., video data) of the pressure measurement file and is returned by the on-demand service node 4.
Step 302, obtaining the pressure measurement index of the on-demand distribution system 3.
The pressure measurement index of the on-demand distribution system 3 refers to the performance index of the on-demand distribution system 3 executing the deployment of the pressure measurement file to the on-demand service node 4 according to the scheduling request and returning the on-demand service node 4 deployed with the pressure measurement file to the client 2.
In this embodiment, the pressure measurement indexes include a file distribution speed, a file deployment number, and a scheduling response time.
The file distribution speed is the speed from when a scheduling request is received from the on-demand distribution system 3 to when the pressure measurement file is deployed to the on-demand service node 4. The file distribution speed may be an average file distribution speed of the on-demand distribution system 3 over a certain time.
The number of file deployment copies is the number of copies of the requested pressure measurement file that the on-demand distribution system 3 deploys to the on-demand service node 4.
The schedule response time is the time from when the schedule request is received from on-demand distribution system 3 to when on-demand service node 4 deploying the pressure measurement file is returned to client 2.
On-demand distribution system 3 may directly record the pressure measurement indicator, such as a log file recorded at on-demand distribution system 3.
Or, the on-demand distribution system 3 may record file deployment information of the pressure measurement file, and the pressure test device 10 of the on-demand distribution system acquires the file deployment information and acquires the pressure measurement index according to the file deployment information. For example, the on-demand distribution system 3 records each on-demand service node 4 that deploys the pressure measurement file, and the on-demand distribution system pressure test device 10 counts the number of file deployments of the pressure measurement file according to each on-demand service node 4 that deploys the pressure measurement file. For another example, on-demand distribution system 3 records the time when on-demand distribution system 3 receives the scheduling request and the time until on-demand service node 4 that deploys the pressure measurement file returns to client 2, and on-demand distribution system pressure testing apparatus 10 calculates the scheduling response time according to the time when on-demand distribution system 3 receives the scheduling request and the time until on-demand service node 4 that deploys the pressure measurement file returns to client 2.
The on-demand distribution system pressure testing device 10 may send a pressure measurement data request to the on-demand distribution system 3, requesting the pressure measurement index or the file deployment information. And after receiving the pressure measurement data request, the on-demand distribution system 3 returns the pressure measurement indexes or the file deployment information to the pressure testing device 10 of the on-demand distribution system. Or, the on-demand distribution system 3 may actively send the pressure measurement index or the file deployment information to the on-demand distribution system pressure testing device 10 according to a preset period, and the on-demand distribution system pressure testing device 10 receives the pressure measurement index or the file deployment information periodically sent by the on-demand distribution system 3.
And 303, judging whether the on-demand distribution system 3 meets the system requirements or not according to the pressure measurement indexes.
It may be determined whether the scheduling response time is less than or equal to a preset time, and if the scheduling response time is less than or equal to the preset time, the on-demand distribution system 3 meets the system requirements. Otherwise, if the scheduling response time is longer than the preset time, the on-demand distribution system 3 does not meet the system requirements.
Or, it may be determined whether the number of file deployment copies is greater than or equal to a preset number of deployment copies, and if the number of file deployment copies is greater than or equal to the preset number of deployment copies, the on-demand distribution system 3 meets the system requirements. Otherwise, if the number of file deployment copies is smaller than the preset number of deployment copies, the on-demand distribution system 3 does not meet the system requirements. And the preset number of deployment copies is determined according to the heat of the pressure measurement file.
Particularly, it may be determined whether the number of file deployment copies of the pressure measurement file in the preset regional operator is greater than or equal to a preset number of deployment copies, and if the number of file deployment copies of the pressure measurement file in the preset regional operator is greater than or equal to the preset number of deployment copies, the on-demand distribution system 3 meets the system requirements. Otherwise, if the number of file deployment copies of the pressure measurement file in the preset regional operator is smaller than the preset number of deployment copies, the on-demand distribution system 3 does not meet the system requirements. And determining the preset deployment number according to the popularity of the pressure measurement file in the preset operator. The judgment of the number of file deployment copies of the pressure-measured file in the preset regional operator is to determine whether the on-demand distribution system 3 has the regional operator hotspot judgment capability, and whether the file deployment can be performed according to the regional operator popularity of the pressure-measured file. Only if the on-demand distribution system 3 deploys a sufficient number of files in the regional operator corresponding to the pressure-measured file, the corresponding scheduling request can be satisfied.
Or, it may be determined whether the file distribution speed is greater than or equal to a preset speed, and if the file distribution speed is greater than or equal to the preset speed, the on-demand distribution system 3 meets the system requirement. Otherwise, if the file distribution speed is lower than the preset speed, the on-demand distribution system 3 does not meet the system requirement.
In order to improve the accuracy of pressure measurement, in this embodiment, determining whether the on-demand distribution system 3 meets the system requirement according to the pressure measurement indicator may include:
(1) for single file pressure measurement, judging whether the file distribution speed is less than or equal to a preset time, if so, enabling the on-demand distribution system 3 to meet the system requirement; otherwise, if the file distribution speed is greater than the preset time, the on-demand distribution system 3 does not meet the system requirements. When a single file is compressed, all clients 2 compress the same file. If the request of the same file falls on a specific on-demand service node, the load of the on-demand service node is high, and other on-demand service nodes without requests are idle. If the scheduling response time of the on-demand distribution system 3 to the single file is longer than the preset time, it indicates that the on-demand distribution system 3 cannot optimize the hot spot processing, and the problem of single-point overheating exists, so that the system requirements are not met.
(2) For the fixed file array pressure measurement, judging whether the file deployment number is greater than or equal to a preset deployment number, if so, enabling the on-demand distribution system 3 to meet the system requirement; otherwise, if the number of file deployment copies is smaller than the preset number of deployment copies, the on-demand distribution system 3 does not meet the system requirements. For example, a pressure measurement file with the scheduling request number greater than or equal to 10000 within a preset time (e.g., 10 minutes) is defined as a high-heat pressure measurement file, and if the file deployment number of the high-heat pressure measurement file is less than or equal to 10000, the on-demand distribution system 3 does not meet the system requirement. Fixed file column pressure measurement scenarios the throughput capability of the on-demand distribution system 3 is primarily measured without new files added.
(3) For the dynamic update file array pressure measurement, judging whether the file distribution speed is greater than or equal to a preset speed, if so, the on-demand distribution system 3 meets the system requirement; otherwise, if the file distribution speed is lower than the preset speed, the on-demand distribution system 3 does not meet the system requirement. The dynamic updating of the file array pressure measurement scene is more suitable for the actual service use of the on-demand distribution system 3, and the file distribution speed is the most important pressure measurement index. Therefore, it can be determined whether the file distribution speed is less than or equal to the preset speed during dynamic update file array pressure measurement, and if the file distribution speed is less than or equal to the preset speed, it indicates that the on-demand distribution system 3 cannot timely deploy the pressure measurement file, so that the system requirements are not met.
The pressure testing method for the on-demand distribution system of the third embodiment is applied to the pressure testing device 10 for the on-demand distribution system, and the method includes: issuing a pressure strategy to a client 2, enabling the client 2 to send a scheduling request for the pressure measurement file to the on-demand distribution system 3 according to the pressure measurement frequency, enabling the on-demand distribution system 3 to deploy the pressure measurement file to an on-demand service node 4 according to the scheduling request, and returning the on-demand service node 4 where the pressure measurement file is deployed to the client 2; acquiring a pressure measurement index of the on-demand distribution system 3; and judging whether the on-demand distribution system 3 meets the system requirements or not according to the pressure measurement indexes. The pressure test method for the on-demand distribution system in the third embodiment can simulate an on-demand request by using the client to perform a pressure test on the on-demand distribution system.
Example four
Fig. 4 is a structural diagram of a preferred embodiment of a pressure testing device of an on-demand distribution system according to an embodiment of the present invention. As shown in fig. 4, the on-demand distribution system pressure testing apparatus 10 may include: issuing unit 401, acquiring unit 402, and determining unit 403.
The issuing unit 401 is configured to issue a pressure policy to the client 2 by the pressure testing device 10 of the on-demand distribution system, where the pressure policy includes a pressure measurement file and a pressure measurement frequency, so that the client 2 sends a scheduling request for the pressure measurement file to the on-demand distribution system 3 according to the pressure measurement frequency, the on-demand distribution system 3 deploys the pressure measurement file to the on-demand service node 4 according to the scheduling request, and the on-demand service node 4 deploying the pressure measurement file is returned to the client 2.
In this embodiment, the stress test for the on-demand distribution system 3 includes a single file stress test, a fixed file list stress test, and a dynamic update file list stress test.
If the unicast distribution system 3 is subjected to a single file pressure test, the pressure test file is a single file.
If the fixed file list pressure test is performed on the multicast distribution system 3, the pressure test file is a file in the fixed file list. For example, a file can be randomly selected from a fixed file list as a compression test file; alternatively, one file may be selected from the fixed file list in a predetermined order as the compression file.
If the pressure test of the dynamic update file list is performed on the multicast distribution system 3, the pressure test file is a file in the dynamic file list. For example, the dynamic file list may be updated according to a preset frequency (e.g., once per hour), and a file is randomly selected from the dynamic file list as a pressure measurement file; or selecting one file from the dynamic file list as a pressure measurement file according to a preset sequence.
The pressure test frequency is a frequency at which the on-demand distribution system 3 is pressure tested. The frequency of pressure measurements may be set as desired, for example, every 20 seconds, every minute, every 10 minutes.
And the client 2 sends a scheduling request for the pressure measurement file to the on-demand distribution system 3 according to the pressure measurement frequency.
If the single file pressure test is performed on the on-demand distribution system 3, the client 2 sends a scheduling request for a single file to the on-demand distribution system 3 according to the pressure test frequency. For example, client 2 sends a scheduling request to the on-demand distribution system 3 every 20s, each time requesting the same file.
If the on-demand distribution system 3 is subjected to the pressure test of the fixed file list, the client 2 sends a scheduling request to the on-demand distribution system 3 according to the pressure test frequency, and requests one file in the fixed list each time. For example, the client 2 sends a scheduling request to the on-demand distribution system 3 every 20s, each time requesting a randomly chosen file from the fixed list.
If the on-demand distribution system 3 is subjected to a pressure test for dynamically updating the file list, the client 2 sends a scheduling request to the on-demand distribution system 3 according to the pressure test frequency, and requests one file in the dynamic file list each time. For example, the client 2 sends a scheduling request to the on-demand distribution system 3 every 20s, each time requesting a randomly selected file from the dynamic file list.
And the on-demand distribution system 3 deploys the pressure measurement file to the on-demand service node 4 according to the scheduling request, and returns the on-demand service node 4 deployed with the pressure measurement file to the client 2.
The on-demand distribution system 3 counts the scheduling request times of the pressure measurement files, obtains the heat of the pressure measurement files according to the scheduling request times of the pressure measurement files, and determines the file deployment number of the pressure measurement files according to the heat of the pressure measurement files.
And if the scheduling request times are more, the hot degree of the pressure file is high. Otherwise, if the number of times of scheduling requests is small, the hot degree of the compression-testing file is low. For example, a pressure measurement file with the scheduling request number greater than or equal to 10000 in a preset time (e.g., 10 minutes) may be defined as a high-heat pressure measurement file, a pressure measurement file with the scheduling request number less than 10000 and greater than or equal to 1000 in the preset time may be defined as a medium-heat pressure measurement file, and a pressure measurement file with the scheduling request number less than 1000 in the preset time may be defined as a low-heat pressure measurement file.
In this embodiment, each scheduling request corresponds to one regional operator. Each on-demand service node also corresponds to a regional carrier. On-demand distribution system 3 also determines the regional operator distribution of the pressure files based on their heat.
A regional operator is a particular network operator for a particular geographic region. The regions may include six geographical regions "east China", "North China", "south China", "northeast", "northwest" and "southwest". The operators can comprise three network operators of 'telecom', 'Unicom' and 'mobile'. Thus, the regional operators may include 18 regional operators, including eastern China telecom, eastern China Union, eastern China Mobile, southern China telecom, southern China Union, southern China Mobile … … southwest China telecom, southwest China Union, and southwest China Mobile.
An obtaining unit 402, configured to obtain a pressure measurement indicator of the on-demand distribution system 3.
In this embodiment, the pressure measurement indexes include a file distribution speed, a file deployment number, and a scheduling response time.
The file distribution speed is the speed from when a scheduling request is received from the on-demand distribution system 3 to when the pressure measurement file is deployed to the on-demand service node 4. The file distribution speed may be an average file distribution speed of the on-demand distribution system 3 over a certain time.
The number of file deployment copies is the number of copies of the requested pressure measurement file that the on-demand distribution system 3 deploys to the on-demand service node 4.
The schedule response time is the time from when the schedule request is received from on-demand distribution system 3 to when on-demand service node 4 deploying the pressure measurement file is returned to client 2.
On-demand distribution system 3 may directly record the pressure measurement indicator, such as a log file recorded at on-demand distribution system 3.
Or, the on-demand distribution system 3 may record file deployment information of the pressure measurement file, and the pressure test device 10 of the on-demand distribution system acquires the file deployment information and acquires the pressure measurement index according to the file deployment information. For example, the on-demand distribution system 3 records each on-demand service node 4 that deploys the pressure measurement file, and the on-demand distribution system pressure test device 10 counts the number of file deployments of the pressure measurement file according to each on-demand service node 4 that deploys the pressure measurement file. For another example, on-demand distribution system 3 records the time when on-demand distribution system 3 receives the scheduling request and the time until on-demand service node 4 that deploys the pressure measurement file returns to client 2, and on-demand distribution system pressure testing apparatus 10 calculates the scheduling response time according to the time when on-demand distribution system 3 receives the scheduling request and the time until on-demand service node 4 that deploys the pressure measurement file returns to client 2.
The on-demand distribution system pressure testing device 10 may send a pressure measurement data request to the on-demand distribution system 3, requesting the pressure measurement index or the file deployment information. And after receiving the pressure measurement data request, the on-demand distribution system 3 returns the pressure measurement indexes or the file deployment information to the pressure testing device 10 of the on-demand distribution system. Or, the on-demand distribution system 3 may actively send the pressure measurement index or the file deployment information to the on-demand distribution system pressure testing device 10 according to a preset period, and the on-demand distribution system pressure testing device 10 receives the pressure measurement index or the file deployment information periodically sent by the on-demand distribution system 3.

It may be determined whether the scheduling response time is less than or equal to a preset time, and if the scheduling response time is less than or equal to the preset time, the on-demand distribution system 3 meets the system requirements. Otherwise, if the scheduling response time is longer than the preset time, the on-demand distribution system 3 does not meet the system requirements.
Or, it may be determined whether the number of file deployment copies is greater than or equal to a preset number of deployment copies, and if the number of file deployment copies is greater than or equal to the preset number of deployment copies, the on-demand distribution system 3 meets the system requirements. Otherwise, if the number of file deployment copies is smaller than the preset number of deployment copies, the on-demand distribution system 3 does not meet the system requirements. And the preset number of deployment copies is determined according to the heat of the pressure measurement file.
Particularly, it may be determined whether the number of file deployment copies of the pressure measurement file in the preset regional operator is greater than or equal to a preset number of deployment copies, and if the number of file deployment copies of the pressure measurement file in the preset regional operator is greater than or equal to the preset number of deployment copies, the on-demand distribution system 3 meets the system requirements. Otherwise, if the number of file deployment copies of the pressure measurement file in the preset regional operator is smaller than the preset number of deployment copies, the on-demand distribution system 3 does not meet the system requirements. And determining the preset deployment number according to the popularity of the pressure measurement file in the preset operator. The judgment of the number of file deployment copies of the pressure-measured file in the preset regional operator is to determine whether the on-demand distribution system 3 has the regional operator hotspot judgment capability, and whether the file deployment can be performed according to the regional operator popularity of the pressure-measured file. Only if the on-demand distribution system 3 deploys a sufficient number of files in the regional operator corresponding to the pressure-measured file, the corresponding scheduling request can be satisfied.
Or, it may be determined whether the file distribution speed is greater than or equal to a preset speed, and if the file distribution speed is greater than or equal to the preset speed, the on-demand distribution system 3 meets the system requirement. Otherwise, if the file distribution speed is lower than the preset speed, the on-demand distribution system 3 does not meet the system requirement.
