However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to a switching method for a source return link, which is applied to an electronic device, such as each node server in a Content Delivery Network (CDN), or a client. The switching method of the back source link is shown in fig. 1, and comprises the following steps:
step 101: and acquiring the communication quality information of the current back source link.
Specifically, when the data in the memory of the electronic device cannot meet the needs of the visitor, the electronic device needs to obtain the needed data in a source returning manner. And the electronic equipment monitors the communication quality of the current link in the process of returning to the source.
In a specific implementation, the communication quality information of the current return-to-source link may include at least one of the first indication information, the second indication information, and communication index data of the current return-to-source link. The communication index data may be any one or any combination of a download rate, a packet loss rate, and a response time of the link.
In a specific implementation, each back source link is provided with a mark for indicating whether the back source link is a healthy link or an unhealthy link. When the electronic equipment requests data from a source station, all source returning links corresponding to the source station are determined, and one source returning link is selected from the source returning links marked as healthy links to serve as the current source returning link.
Step 102: and determining a switching strategy of the back source link according to the communication quality information of the current back source link.
Specifically, the switching policy is to continue using the current back-source link or to switch from the current back-source link to another back-source link.
In a specific implementation, when the communication quality information of the current back-to-source link indicates that the communication quality of the current back-to-source link is poor, the electronic device determines that the handover policy is to be switched from the current back-to-source link to another back-to-source link, and when the communication quality information of the current back-to-source link indicates that the communication quality of the current back-to-source link is good, determines that the handover policy is to continue using the current back-to-source link.
In a specific implementation, the communication quality information of the current return-to-source link is communication index data of the current return-to-source link. The electronic equipment judges whether the communication index data of the current return link meets the preset requirement; if so, determining that the switching strategy is to continue using the current back-source link, otherwise, determining that the switching strategy is to switch from the current back-source link to other back-source links.
In another specific implementation, the communication quality information of the current back-to-source link is first indication information and communication index data of the current back-to-source link, where the first indication information indicates whether the source station returns response data. The electronic equipment judges whether the first indication information indicates that the source station does not return response data; if the first indication information indicates that the source station does not return response data, determining that the switching strategy is switched from the current back-to-source link to other back-to-source links; if the first indication information indicates that the source station returns response data is determined, judging whether the communication index data of the current return link meets the preset requirement; and if the communication index data of the current back-source link does not meet the preset requirement, determining that the switching strategy is to continue using the current back-source link, otherwise, determining that the switching strategy is to switch from the current back-source link to other back-source links.
In another specific implementation, the communication quality information of the current back-to-source link is second indication information and communication index data of the current back-to-source link, where the second indication information is used to indicate whether response data returned by the source station is an error status code. The electronic equipment judges whether the second indication information indicates that the response data returned by the source station is an error state code; if the second indication information indicates that the response data returned by the source station is the error state code, determining that the switching strategy is to be switched from the current source returning link to other source returning links; if the second indication information indicates that the response data returned by the source station is not the error state code, judging whether the communication index data of the current source returning link meets the preset requirement; and if the communication index data of the current back-source link does not meet the preset requirement, determining that the switching strategy is to continue using the current back-source link, otherwise, determining that the switching strategy is to switch from the current back-source link to other back-source links.
It should be noted that, as can be understood by those skilled in the art, the current communication quality information of the return-to-source link may also be information reflecting the communication quality of the return-to-source link, which is not listed here, and in practical applications, any one or more information reflecting the communication quality of the return-to-source link may be selected as the communication quality information according to needs.
Step 103: and switching the current back-source link after determining that the switching strategy is to switch from the current back-source link to other back-source links.
In a specific implementation, after switching a current back-to-source link, the electronic device determines the number of times of switching the current back-to-source link. And the electronic equipment judges whether to mark the current back source link according to the switching times of the current back source link. Specifically, if the number of times of switching the current return-to-source link is high, which indicates that the communication quality of the current return-to-source link cannot meet the requirement for a long time, the electronic device may mark the current return-to-source link to avoid selecting the return-to-source link again.
In a specific implementation, each back source link is provided with a mark for indicating whether the back source link is a healthy link or an unhealthy link. When the electronic equipment is switched back to the source link, the current back to source link is switched to other back to source links marked as healthy links. For example, the back-source link between the electronic device and the source station includes link a, link B, and link C. When the electronic equipment returns to the source, the link A is determined to be a healthy link, and data is downloaded through the link A. In the downloading process, the communication quality of the link A is suddenly reduced, the electronic equipment firstly judges whether the link B is marked as an unhealthy link, if the link B is marked as the unhealthy link, the link B is directly switched to the link C, and if the link B is not marked as the unhealthy link, the link B is directly switched to the link B.
It should be noted that, as can be understood by those skilled in the art, after the electronic device completes one back-source request, the back-source link used in the back-source request may be scored or graded according to the communication quality information of the back-source link used in the back-source request.
It is worth mentioning that the electronic device scores or ranks the back source links, so that when the electronic device returns the source next time, a link with the best communication quality can be selected as the current back source link according to the score or rank of each back source link, thereby further improving the back source efficiency.
The above description is only for illustrative purposes and does not limit the technical aspects of the present invention.
Compared with the prior art, the switching method of the source return link provided in the embodiment monitors the communication quality of the current source return link, and switches to other source return links in time when the communication quality of the current source return link is poor, so that the influence of network fluctuation on the current source return connection can be effectively prevented, the problem that the source return efficiency is low or the source return fails due to the fact that the current source return link is continuously used when the communication quality of the source return link is poor by the electronic device is avoided, the flexibility and timeliness of switching of the source return link are improved, and the source return efficiency of the electronic device is improved. In addition, the electronic equipment automatically determines whether the current source returning link needs to be switched, interaction with a dispatching center is not needed, dependency of the electronic equipment on the dispatching center is reduced, source returning delay and source station response time are reduced, and user experience is improved.
The second embodiment of the invention relates to a switching method of a return link, which is applied to electronic equipment. This embodiment is a further refinement of the first embodiment, and specifically describes a specific execution procedure of step 102 when the communication quality information of the current back-to-source link includes the first instruction information, the second instruction information, and the communication index data of the current back-to-source link. As shown in fig. 2, in this embodiment, the method for switching the back-source link includes the following steps:
step 201: and acquiring the first indication information, the second indication information and the communication index data of the current back source link.
Step 202: and judging whether the first indication information indicates that the source station does not return response data.
Specifically, in the case where a problem occurs in the function of the source station or the connection of the source return link fails, the source station cannot respond to the source return request of the electronic device. If the electronic device receives the response data of the source station within the first preset time of sending the request to the source, the first indication information indicates that the source station returns the response data, step 203 is executed, and if the response data of the source station is not received and the first indication information indicates that the source station does not return the response data, step 207 is executed.
Step 203: and judging whether the second indication information indicates that the response data returned by the source station is an error state code.
Specifically, after receiving the response data from the source station, the electronic device determines whether the response data is an error status code, and determines the second indication information according to the determination result. If the second indication information indicates that the response data returned by the source station is not an error status code, step 204 is executed, and if the second indication information indicates that the response data returned by the source station is an error status code, step 207 is executed. For example, if the response data of the source station is 5XX (503, 504, etc. indicate a status code of the response exception), the second indication information indicates that the response data returned by the source station is an error status code, and the electronic device determines that the switching policy is to switch from the current back-to-source link to another back-to-source link.
Step 204: and judging whether the communication index data of the current return source link meets the preset requirement.
Specifically, the preset requirement may be that each communication index in the communication index data of the current back-to-source link is greater than a preset threshold. If the electronic device determines that the communication index data of the current return link meets the preset requirement, step 205 is executed, otherwise, step 207 is executed.
In a specific implementation, in order to monitor the communication quality of the return link in real time, the electronic device may obtain the communication index data of the current return link for multiple times. For example, the electronic device calculates the communication quality of the return link within the period time with the time T as the period, and in the current time period T1, when the communication index data of the current return link reaches the threshold, the communication index data of the current return link is recalculated in the next time period T2, if the communication index data reaches the threshold, the switching is not performed, otherwise, the switching is performed to other return links, and the process is repeated until the end.
It should be noted that, as can be understood by those skilled in the art, the electronic device may also acquire, at the initial stage of returning to the source, the communication index data of the current returning-to-source link at the first frequency, and if the communication index data of the current returning-to-source link acquired at the initial stage all meets the preset requirement, acquire, at the second frequency, the communication index data of the current returning-to-source link, where the second frequency is smaller than the first frequency. The present embodiment does not limit the number of times and the manner of acquiring the communication index data of the current return link by the electronic device.
Step 205: and determining the switching strategy as continuing to use the current back-source link.
Step 206: the current back-source link continues to be used. The flow is then ended.
Step 207: and determining that the switching strategy is to switch from the current back source link to other back source links.
Step 208: and switching to other back source links.
Specifically, the electronic device selects one back-source link marked as a healthy link from other back-source links, and switches from the current back-source link to the other back-source links marked as healthy links.
In a specific implementation, each return link between the electronic device and the source station supports breakpoint continuous transmission. The electronic device may continue to complete incomplete downloads at the data breakpoint after switching to other back-to-source links. For example, the source return link between the electronic device and the source station comprises a link A and a link B, the file size of the source return request of the electronic device is 3M, 1M is downloaded on the link A, at this time, the link A suddenly has a quality problem and is determined to be an unhealthy link, and the electronic device is switched from the link A to the link B, and the downloading is continued on the link B from the place of 1M.
It is worth mentioning that after switching to other source return links, the electronic device can continue to transmit at a breakpoint, thereby avoiding the waste of downloaded data before switching and effectively reducing the waste of source return bandwidth.
It should be noted that, in this embodiment, for clarity of illustration, the first indication information, the second indication information, and the communication index data of the current back-source link are obtained as previous steps from step 202 to step 204, and in practical applications, the electronic device may obtain the data in stages, that is, the electronic device may obtain the first indication information before performing step 202, obtain the second indication information after performing step 202 and before performing step 203, and obtain the communication index data after performing step 203 and before performing step 204, which does not limit the specific time when the electronic device obtains the information.
The switching method of the back source link is described below with reference to practical situations. Assume that a configured link of a certain frequency channel includes a primary source station and a secondary source station, a link corresponding to the primary source station includes a link a, a link B, and a link C, and a link corresponding to the secondary source station includes a link D and a link E. When a user accesses a Uniform Resource Locator (URL), if the resolved CDN node server does not cache the corresponding content, or the cached content is expired, the CDN node server returns to the source station to obtain the corresponding content. When the CDN node server returns to the source, the link A is selected as a source returning link, and a source returning request is sent to the main source station. If the main source station responds to the request, the CDN service node judges whether response data of the main source station are error state codes or not, if not, the CDN node server calculates the downloading rate of the link A within the appointed time, if the downloading rate of the link A within the appointed time is lower than a set threshold value, the link A is considered to be unhealthy, the link A is switched to the link B, whether the downloading rate of the link B is greater than the threshold value or not is judged, and if not, the link B is determined to be unhealthy, the link C is switched to. When the link A, the link B and the link C of the main source station are unhealthy, switching to the standby source station, and carrying out similar switching logic operation on the link D and the link E of the standby source station.
It should be noted that, when a certain channel or website is only provided with a main source station, the electronic device may switch between the source return links corresponding to the main source station, that is, between link a, link B, and link C, and when a certain channel or website is provided with a main source station and a standby source station, the electronic device may switch between the source return link corresponding to the main source station and the source return link corresponding to the standby source station.
The above description is only for illustrative purposes and does not limit the technical aspects of the present invention.
Compared with the prior art, the switching method of the source return link provided in the embodiment monitors the communication quality of the current source return link, and switches to other source return links in time when the communication quality of the current source return link is poor, so that the influence of network fluctuation on the current source return connection can be effectively prevented, the problem that the source return efficiency is low or the source return fails due to the fact that the current source return link is continuously used when the communication quality of the source return link is poor by the electronic device is avoided, the flexibility and timeliness of switching of the source return link are improved, and the source return efficiency of the electronic device is improved. In addition, the electronic equipment automatically determines whether the current source returning link needs to be switched, interaction with a dispatching center is not needed, dependency of the electronic equipment on the dispatching center is reduced, source returning delay and source station response time are reduced, and user experience is improved. In addition, after the electronic equipment is switched to other source return links, the transmission can be continued at a breakpoint, the waste of downloaded data before switching is avoided, and the waste of source return bandwidth is effectively reduced.
The third embodiment of the present invention relates to a method for switching a back source link, which is a further improvement of the first embodiment, and the specific improvement is as follows: after the electronic device determines that the switching policy is to switch from the current back-source link to another back-source link, other related steps are added.
Specifically, as shown in fig. 3, the present embodiment includes steps 301 to 308, where steps 301 and 302 are substantially the same as steps 101 and 102 of the first embodiment, respectively, and are not repeated here. The following mainly introduces the differences:
step 301 and step 302 are performed.
Step 303: and judging whether the switching strategy is to be switched from the current back source link to other back source links.
Specifically, if the electronic device determines that the handover policy is to switch from the current back-source link to another back-source link, step 305 is performed, otherwise, step 304 is performed.
Step 304: and continuing to download data by using the current back source link. The flow is then ended.
Step 305: and determining the switching times of the current back source link.
Specifically, the electronic device counts the number of times of switching of each return link. In the process of returning to the source by using a certain back-source link, if the switching strategy is an event of switching from the current back-source link to other back-source links, adding 1 to the switching times corresponding to the back-source link.
Step 306: and judging whether the switching times of the current back source link is greater than a first preset value.
Specifically, if the number of times of switching the current back-source link is greater than the first preset value, step 307 is executed, otherwise, step 308 is executed, where the first preset value may be set according to an actual situation.
Step 307: the current back-source link is marked as an unhealthy link.
Specifically, if the switching times of the current back-source link is greater than a first preset value, it is indicated that the current back-source link is in an unstable state in the near future, and the electronic device marks the current back-source link as an unhealthy link, so that the electronic device can be prevented from using the back-source link in the near future and affecting back-source efficiency. For example, when the number of handovers reaches M times in N back-source requests made using back-source link a, back-source link a is marked as an unhealthy link. Wherein, N is the statistical period, and M is the first default, can set up according to actual conditions.
Step 308: and switching to other back source links.
It should be noted that, for clarity, in this embodiment, steps 305 to 307 are taken as steps before step 308, and in practical applications, steps 305 to 307 may also be taken as steps after step 308, and this embodiment does not limit the execution sequence of steps 305 to 307 and step 308.
Compared with the prior art, in the switching method of the source return link provided in the embodiment, after the number of times that the communication quality of the current source return link does not meet the requirement reaches the first preset value, the current source return link is marked as an unhealthy link, so that the electronic device is prevented from using the source return link in the near future, and the source return efficiency is further improved.
A fourth embodiment of the present invention relates to a method for switching a back source link, and the present embodiment is a further improvement of the first embodiment, and the specific improvement is as follows: in this embodiment, the selected back-source link is determined according to the current total number of back-source links. As shown in fig. 4, the method for switching back to the source link includes the following steps:
step 401: and determining the current total times of returning to the source.
Step 402: and judging whether the current total times of returning to the source is greater than a second preset value.
Specifically, the electronic device marks each of the back-source links to determine whether the back-source link is a healthy link or an unhealthy link. The electronic equipment counts the times of returning to the source through a counter, and the value of the counter is added with 1 each time of returning to the source. When the electronic equipment selects the back source link, the healthy back source link or the unhealthy back source link is selected for back source according to the current total times of back source. If the current total number of times of returning to the source is not greater than the second preset value, step 403 is executed, and if the current total number of times of returning to the source is greater than the second preset value, step 407 is executed. Wherein, the second preset value can be set according to the requirement.
It should be noted that, as can be understood by those skilled in the art, in order to avoid that the electronic device always selects the source returning link marked as an unhealthy link as the current source returning link after the current source returning total number reaches the second preset value, the current source returning total number may be cleared when the current source returning total number exceeds the second preset value.
It should be noted that, in practical applications, as will be understood by those skilled in the art, each source return link may correspond to a counter, the counter starts counting when the source return link corresponding to the counter is marked as an unhealthy link, the electronic device increments the count value by 1 each time the electronic device returns the source, and sends a prompt message to a processor of the electronic device when the count value reaches a second preset value. And the processor of the electronic equipment selects the back source link when the back source link is next back source so as to detect the back source link again and determine the current communication quality of the back source link.
It is worth mentioning that when the total number of times of returning to the source reaches the second preset value, the returning source link marked as the unhealthy link is called again, so that the phenomenon that the returning source link marked as the unhealthy link cannot be used after the communication quality is recovered is avoided, and resource waste is caused.
Step 403: and selecting one back source link from the back source links marked as healthy links as the current back source link.
Step 404: and acquiring the communication quality information of the current back-to-source link, and determining a switching strategy according to the communication quality information of the current back-to-source link.
Step 405: and judging whether the switching strategy is to continue using the current back source link. If yes, go to step 406, otherwise, go to step 411.
Step 406: and continuing to download data by using the current back source link. The flow is then ended.
Specifically, steps 404 to 406 may refer to the description of the handover method for the back source link in the first embodiment, and will not be described in detail here.
Step 407: and selecting one back source link from the back source links marked as unhealthy links as the current back source link.
Step 408: and acquiring the communication quality information of the current back-to-source link, and determining a switching strategy according to the communication quality information of the current back-to-source link.
Step 409: and judging whether the switching strategy is to continue using the current back source link. If yes, go to step 410, otherwise, go to step 411.
Step 410: and marking the current back source link as a healthy link, and continuing to use the current back source link to download data. The flow is then ended.
Specifically, when the handover policy is to continue using the current back-source link, it is described that the communication quality information of the current back-source link indicates that the communication quality of the current back-source link is good, the electronic device marks the back-source link as a healthy link, and then the back-source link can be returned through the current back-source link, thereby avoiding resource waste.
Step 411: and switching to other back source links, and continuously downloading the data through the other back source links.
It should be noted that, as can be understood by those skilled in the art, in practical applications, the electronic device may mark the current back-source link as a healthy link after the communication quality information of the current back-source link indicates that the communication quality of the current back-source link is good, and mark the current back-source link as an unhealthy link after the communication quality information of the current back-source link indicates that the communication quality of the current back-source link is poor, and this embodiment does not limit a specific time when the electronic device changes the mark of the back-source link.
The switching method of the back source link is described below with reference to practical situations. Assume that link a between the electronic device and the source station has been marked as an unhealthy link and link B is marked as a healthy link. When the number of times of source return reaches G (G is a positive integer greater than 1), the electronic device retries source return through the link A. If the communication quality information of the link A indicates that the communication quality of the link A is good and no switching event occurs in the source returning process, the link A is marked as a healthy link after the source returning request is finished. If the communication quality information of the link A indicates that the communication quality of the link A is poor in the source returning process, the link A is switched to the link B, and the mark of the link A is not changed.
It is worth mentioning that when the total number of times of returning to the source reaches the second preset value, the returning source link marked as the unhealthy link is called again, so that the phenomenon that the returning source link marked as the unhealthy link cannot be used after the communication quality is recovered is avoided, and resource waste is caused.
Compared with the prior art, according to the switching method of the source returning link, the electronic device selects the source returning link marked as the healthy link as the current source returning link in the normal source returning request, so that the source returning efficiency is further improved, and when the total source returning times reach the second preset value, the source returning link marked as the unhealthy link is called again, so that the problem that the source returning link marked as the unhealthy link cannot be used after the communication quality is recovered is avoided, and the resource waste is caused.
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.
