With the development of internet financial science and technology, the rapid growth of internet users promotes the vigorous development of internet economy. In particular, in the data transmission process between large financial application networks, the rationality of traffic distribution between an upstream network system and a downstream network system plays a direct key role in user experience.

It will be appreciated by those skilled in the art that the structure shown in fig. 1 is merely a block diagram of a portion of the structure associated with the present inventive arrangements and is not limiting of the application environment in which the present inventive arrangements are applied, and that a particular application environment may include more or less components than those shown, or may combine some components, or have a different arrangement of components.
In one embodiment, as shown in fig. 2, a flow distribution method is provided, and the method is applied to the intermediate device in fig. 1 for illustration, and includes the following steps:
s201, receiving a service request sent by an upstream network system.
Wherein the upstream network system represents a party relatively close to the user or client in the network, and is configured to receive the service request from the user or client and transmit it to the downstream network system for processing, such as an internet banking system of a bank or an investment transaction application. The downstream network system represents a party relatively far from a user or a client in the network, and is used for receiving the service request transmitted by the upstream network system, and performing corresponding processing and response, such as a core banking system, a payment system, an air control system and the like of a bank. The service request means a request for the upstream network system to instruct the upstream network system to perform a specific service operation or acquire related information, and the service request includes parameters and instructions.
The method is characterized in that an online banking example is used for describing, a user logs in a bank account by using an upstream network system, logs in the bank account, inquires balance, transfer accounts and the like, then requests for transfer accounts, inquires accounts and the like through the upstream system, and then waits for a response of the bank. The user interaction with the platform is performed through an upstream network system (such as a front end server), the upstream network system receives the user request and transmits the request to a downstream network system (such as a core banking system, a payment system, an air control system and the like), and the downstream network system verifies the user account and transaction availability in real time and returns the result to the upstream system so as to provide transfer feedback for the user. Taking a transaction platform in the financial field as an example, the user uses an internet banking or investment transaction application to conduct transactions with a financial institution. The request of the user is sent to the downstream network system (such as an accounting system, a wind control system, a settlement system and the like) through the upstream network system (such as a front end server), the downstream network system performs verification, authorization, processing and settlement according to the transaction request of the user, generates a corresponding result, sends the related result back to the upstream network system, and finally returns to the user. In the embodiment of the application, the upstream network system can firstly establish communication connection with the intermediate equipment through the network protocol, then send the service request to the intermediate equipment, and the intermediate equipment can receive the service request sent by the upstream network system.
S202, determining a target area corresponding to the service request according to the flow ratio of all areas where the downstream network system corresponding to the upstream network system is located based on a preset allocation rule.
Wherein, the allocation rule represents a policy for allocating network traffic, and the preset allocation rule comprises a random allocation rule or a statistical allocation rule. The random allocation rule indicates a rule for randomly allocating the service request in a certain manner. For example, when a service request is received, the intermediate device may perform a formula calculation for the service request to obtain a calculation result. If the downstream network system comprises two areas, the service request can be allocated to the first area when the calculation result meets the first condition; and when the calculation result meets the second condition, allocating the service request into a second area. If the downstream network system comprises three areas, the service request can be allocated to the first area when the calculation result meets the first condition; when the calculation result meets a second condition, dividing the service request into a second area; and when the calculation result meets a third condition, allocating the service request into a third area, and so on. For a certain service request, according to the calculation result, the service request may be allocated to any area in all areas where the downstream network system is located, so that the allocation rule is randomly allocated.
The statistical allocation rule indicates an allocation rule that the number of service requests needs to be counted in the allocation process. For example, when receiving service requests, counting the number of the service requests, if the downstream network system includes two areas, the service requests with the number of the service requests smaller than a first preset value can be distributed to the first area, and the service requests with the number of the service requests between the first preset value and a second preset value can be distributed to the second area; if the downstream network system comprises three areas, service requests with the number of service requests smaller than a first preset value can be distributed to the first area, and service requests with the number of service requests between the first preset value and a second preset value can be distributed to the second area; and distributing the service requests with the number of the service requests between the second preset value and the third preset value to the second area, and the like. The target area is the area that receives the service request. The traffic proportion of all areas represents the ratio of traffic load capacity of all areas, and the ratio of the number of servers of all areas can be taken as the traffic proportion of all areas. For example, if the ratio of the number of servers in the area a to the number of servers in the area B is 4:1, the flow ratio of the area a to the area B is 4:1.
In the embodiment of the application, the intermediate device can obtain the number of servers in each area where the downstream network system is located in advance, then determine the flow ratio of all areas according to the number of servers in each area, and then set a random allocation rule or a statistical allocation rule according to the flow ratio of each area. After the intermediate device receives the service request sent by the upstream network system based on the steps, the target area for receiving the service request can be determined according to a preset random allocation rule or a statistical allocation rule.
S203, distributing the service request to the target area.
In the embodiment of the application, after the intermediate device determines the target area corresponding to the service request based on the steps, the service request can be transmitted to the target area through a correct network path according to the network topology structure and configuration of the target area.
In the above flow distribution method, the intermediate device receives the service request sent by the upstream network system, then determines a target area corresponding to the service request according to the flow ratio of all areas where the downstream network system corresponding to the upstream network system is located based on a preset distribution rule, and finally distributes the service request to the target area, where the preset distribution rule includes a random distribution rule or a statistical distribution rule. In the method, the distribution rule is determined according to the flow ratio of all areas where the downstream network system is located, and the flow ratio can reflect the flow load condition of each area in real time and truly, so that the service request can be reasonably distributed to each target area through the distribution rule, and further the balanced distribution of the flow is realized.
In an embodiment, there is further provided a step of obtaining a target area corresponding to the service request, where the preset allocation rule is a random allocation rule, as shown in fig. 3, and the step S202 of determining the target area corresponding to the service request according to the traffic proportion of all areas where the downstream network system corresponding to the upstream network system is located by using the preset allocation rule as the random allocation rule includes:
s301, determining a first preset parameter and a second preset parameter according to the flow ratio.
Wherein the first preset parameter and the second preset parameter represent two parameters for calculation when determining the random allocation rule.
In the embodiment of the application, after the intermediate device obtains the flow ratio of all the areas where the downstream network system is located based on the steps, the value range of the first preset parameter can be determined according to the values of the flow ratio front term and the flow ratio rear term, and the value of the second preset parameter can be determined according to the values of the flow ratio front term and the flow ratio rear term. For example, the values of the flow ratio front term and the flow ratio rear term may be summed, and the value range of the first preset parameter may be determined according to the summation result, or the value range of the first preset parameter may be determined according to the multiple of the summation result, and then a random number may be randomly generated in the value range of the first preset parameter, and the random number may be used as the first preset parameter. And the values of the flow ratio front term and the flow ratio rear term can be summed, and the summation result or the multiple of the summation result is taken as a second preset parameter. For another example, the values of the flow ratio front term and the flow ratio rear term may be calculated mathematically, the value range of the first preset parameter is determined according to the calculation result, then a random number is randomly generated in the value range of the first preset parameter, and the random number is used as the first preset parameter. And the values of the flow ratio front term and the flow ratio rear term can be calculated mathematically, and the calculated result or the multiple of the summation result is used as a second preset parameter. It can be understood that the first preset parameter and the second preset parameter are determined based on the principle that the ratio of the number of service requests allocated to each area is the flow ratio of each area.
S302, determining a target area corresponding to the service request according to the first preset parameter and the second preset parameter.
In the embodiment of the application, after the intermediate device obtains the first preset parameter and the second preset parameter based on the steps, the intermediate device can calculate the first preset parameter and the second preset parameter to obtain a calculation result. If the downstream network system comprises two areas, the service request can be allocated to the first area when the calculation result meets the first condition; and when the calculation result meets the second condition, allocating the service request into a second area. If the downstream network system comprises three areas, the service request can be allocated to the first area when the calculation result meets the first condition; when the calculation result meets a second condition, dividing the service request into a second area; and when the calculation result meets a third condition, allocating the service request into a third area.
In the above embodiment, since the first preset parameter and the second preset parameter are determined based on the ratio of the number of service requests allocated to each area as the flow ratio of each area, and the allocation rule is quantized by mathematical calculation, the balanced allocation of the flows can be more accurately realized.
In one embodiment, there is further provided a step of acquiring the first preset parameter and the second preset parameter, as shown in fig. 4, the "determining the first preset parameter and the second preset parameter according to the flow ratio" in the step S301 includes:
s401, determining a first preset parameter according to the multiple of the sum of the proportional front term and the proportional rear term corresponding to the flow rate proportion.
In this embodiment of the present application, after obtaining the flow ratios of all the areas where the downstream network system is located by using the intermediate device based on the foregoing steps, the intermediate device may sum the proportion front term and the proportion rear term corresponding to the flow ratio to obtain a summation result, then determine a multiple of the summation result, and determine a value range of the first preset parameter according to the multiple of the summation result, so that the first preset parameter may be randomly generated in the value range of the first preset parameter. For example, if the flow ratio of the area a to the area B is 4:1, the value range of the first preset parameter may be 1 to 5, and the first preset parameter may be 1, 2, 3, 4, or 5. Optionally, the range of the first preset parameter may be 1 to 10, 1 to 15, and so on. For another example, if the flow ratio of the area a, the area B, and the area C is 1:2:3, the value range of the first preset parameter may be 1 to 6, and the first preset parameter may be 1, 2, 3, 4, or 5. Optionally, the range of the first preset parameter may be 1 to 12, 1 to 18, etc.
S402, determining a second preset parameter according to the sum of a proportion front term and a proportion rear term corresponding to the flow proportion.
In the embodiment of the application, after the intermediate device obtains the flow rate ratios of all the areas where the downstream network system is located based on the steps, the intermediate device can sum the proportional front term and the proportional rear term corresponding to the first preset parameter and the flow rate ratio to obtain a summation result, and the summation result is directly used as the second preset parameter. For example, if the flow ratio of the area a to the area B is 4:1, the second preset parameter is 5. For another example, if the flow ratio of the area a, the area B, and the area C is 1:2:3, the second preset parameter is 6.
In an embodiment, there is further provided a step of acquiring a target area corresponding to the service request, as shown in fig. 5, in the step S302, the step of determining the target area corresponding to the service request according to the first preset parameter and the second preset parameter includes:
s501, performing a residual operation on the first preset parameter and the second preset parameter to obtain a residual value.
In the embodiment of the application, after the intermediate device obtains the first preset parameter and the second preset parameter based on the steps, the intermediate device can perform remainder calculation on the first preset parameter according to the second preset parameter to obtain the remainder value. For example, if the flow ratio of the area a to the area B is 4:1, the first preset parameter is a random number 3 in 1 to 10, and the second preset parameter is 5, the first preset parameter is calculated according to the second preset parameter, which may be expressed as 5 to 3, and the remainder value is 3. If the flow ratio of the area A, the area B and the area C is 1:2:3, the first preset parameter is a random number 4 in 1 to 6, and the second preset parameter is 6, the first preset parameter is subjected to remainder according to the second preset parameter, and the remainder can be expressed as 4 to 6, so that the remainder value is 4.
S502, determining a target area corresponding to the service request according to the remainder value.
In the embodiment of the application, after the intermediate device calculates the remainder value corresponding to a certain service request based on the steps, the intermediate device can judge whether the remainder value meets the set condition, if yes, the service request is distributed to a certain area, and if not, the service request is distributed to other areas. Optionally, the target area corresponding to the service request can be determined according to the specific value of the remainder value.
In the above embodiment, the first preset parameter and the second preset parameter are calculated by a remainder, so that the service quantity is distributed proportionally, which is helpful to avoid the overload of some areas and the lower load of other areas, and improve the load balancing effect of the whole system.
In one embodiment, there is further provided a step of obtaining a target area corresponding to the service request, where "determining the target area corresponding to the service request according to the remainder value" in step S502 includes: when the remainder value is a target value, the region corresponding to the target value is used as a target region corresponding to the service request according to the corresponding relation between the value and the region.
The target value indicates a value corresponding to a case where the remainder value satisfies a predetermined condition, for example, the remainder value is greater than 0, and the target value may be 1 or 3 or the like, which is greater than 0. The corresponding relation between the values and the areas indicates that the values meeting a certain condition have a one-to-one correspondence with the areas, and the corresponding relation between the values and the areas is determined according to the flow ratio.
In the embodiment of the application, after the intermediate device obtains the remainder value based on the steps, the intermediate device can judge whether the remainder value meets the preset condition, and further determine the target area under the condition that the remainder value meets or does not meet the preset condition, if the downstream network system comprises two areas, the service request can be allocated to the first area when the remainder value meets the first condition; and when the remainder value meets a second condition, allocating the service request into a second area. For example, the service request is assigned to region B when the remainder value is 0, and the service request is assigned to region a when the remainder value is not 0. Specifically, for a certain service request, the flow ratio of the area a to the area B is 4:1, if the first preset parameter is a random number 3 in 1 to 10, and the first preset parameter is 5, the first preset parameter is subjected to remainder according to the second preset parameter, which can be expressed as 5 to 3, and the remainder value is 3, so that the remainder value is not 0, and the service request is distributed to the area B. If the first preset parameter is a random number 5 in 1 to 10, and the first preset parameter is 5, the first preset parameter is subjected to remainder according to the second preset parameter, which can be expressed as 5 to 5, so that a remainder value is 0, and the service request is distributed to the area A. If the downstream network system comprises three areas, the service request can be allocated to the first area when the remainder value meets the first condition; when the remainder value meets a second condition, dividing the service request into a second area; and when the remainder value meets a third condition, allocating the service request into a third area. For example, for a certain service request, the flow ratio of the area a, the area B and the area C is 1:2:3, the range of the first preset parameter may be any one value of the random numbers 1,2,3,4,5 and 6 in 1 to 6, the first preset parameter is subjected to the remainder according to the second preset parameter, which may be represented as any one value of 1,2,3,4,5 and 6, the remainder is calculated to 6, the remainder value may be 1,2,3,4,5,0, when the remainder value is 0, the service request is allocated to the area a, when the remainder value is 1 or 2, the service request is allocated to the area B, and when the remainder value is any one value of 3,4 and 5, the service request is allocated to the area C. Alternatively, the service request is assigned to region a when the remainder value is 3, to region B when the remainder value is 4 or 0, and to region C when any one of the remainder values 1,2, 5. It can be understood that the proportion of the number of service requests finally allocated to each area is the flow proportion of each area and is also the proportion of the number of servers of each area. Further, the second preset parameter may be stored in a database or a dis, so as to be convenient and flexible to adjust according to the flow ratio.
In the above embodiment, the service number is further distributed in proportion by judging the condition that the residual value meets, which is helpful to avoid the condition that some areas are overloaded and other areas are loaded lower, so as to improve the load balancing effect of the whole system.
In an embodiment, a step of obtaining a target area corresponding to a service request is further provided, where the preset allocation rule is a statistical allocation rule, as shown in fig. 6, in the step S202, the determining, according to the traffic proportion of all areas where the downstream network system corresponding to the upstream network system is located, the target area corresponding to the service request includes:
s601, determining the expected request quantity corresponding to each area according to the flow rate proportion of all areas.
The statistical allocation rule indicates an allocation rule that the number of the service requests needs to be counted in the allocation process.
In the embodiment of the application, after the intermediate device obtains the service request based on the steps, the corresponding expected request quantity can be determined according to the proportion front item and the proportion rear item of the flow proportion. For example, if the flow ratio of the area a to the area B is 4:1, the expected number of requests corresponding to the area a may be 4, and the expected number of requests corresponding to the area B may be 1. For another example, if the traffic ratio of the area a, the area B, and the area C is 1:2:3, the expected request number corresponding to the area a may be 1, the expected request number corresponding to the area B may be 2, and the expected request number corresponding to the area C may be 3.
S602, determining the accumulated number of the currently received service requests, and taking the area corresponding to the accumulated number of the service requests as a target area according to the corresponding relation between the expected request number and the area.
Wherein the accumulated number is the number of accumulated received service requests in one cycle.
In the embodiment of the application, the intermediate device can determine the upper limit of the accumulated quantity according to the flow rate proportion, and the upper limit can be the sum of the front term proportion and the rear term proportion of the flow rate proportion. After the intermediate device determines the number of expected requests corresponding to each area based on the foregoing steps, the currently received service requests may be accumulated, and if the downstream network system includes two areas, the service requests whose number of service requests is smaller than the first preset value may be allocated to the first area, and the service requests whose number of service requests is between the first preset value and the second preset value may be allocated to the second area. For example, if the flow ratio of the area a to the area B is 4:1, in one cycle, the upper limit of the cumulative number is 5, based on the expected request number corresponding to the area a determined in the above step being 4, the expected request number corresponding to the area B may be 1, the service request with the cumulative number of the current service request being less than or equal to 4 may be allocated to the area a, the service request with the cumulative number of the previous service request being greater than or equal to 4 and less than or equal to 5 may be allocated to the area B, and then the cumulative number is cleared, and the cycle is ended. It will be appreciated that the first 4 service requests are allocated to zone B, the 5 th service request is allocated to zone a, the accumulated number is cleared, and the cycle is ended, with the next time the accumulation is continued again. Optionally, the service request when the accumulated number of the current service requests is 1 may be allocated to the area B, the service request with the accumulated number of the previous service requests greater than 1 and less than or equal to 5 may be allocated to the area a, and then the accumulated number is cleared, and the cycle is ended. It will be appreciated that the 1 st service request is allocated to zone B, the last 4 service requests are allocated to zone a, the accumulated number is cleared, and the cycle is ended, with the next iteration continuing to re-accumulate.
If the downstream network system comprises three areas, service requests with the number of service requests smaller than a first preset value can be distributed to the first area, and service requests with the number of service requests between the first preset value and a second preset value can be distributed to the second area; and distributing the service requests with the number of the service requests between the second preset value and the third preset value to the second area, and the like. The target area is the area that receives the service request. For example, if the flow ratio of the area a, the area B, and the area C is 1:2:3, in one cycle, the upper limit of the cumulative number is 6, the number of expected requests corresponding to the area a determined based on the above steps is 1, the number of expected requests corresponding to the area B may be 2, the number of expected requests corresponding to the area C may be 3, the service request with the cumulative number of current service requests being 1 or less may be allocated to the area a, the service request with the cumulative number of previous service requests being 1 or less and 3 or less may be allocated to the area B, the service request with the cumulative number of previous service requests being 3 or more and 6 or less may be allocated to the area C, and then the cumulative number is cleared, and the cycle is ended. It will be appreciated that the first 1 service request is allocated to zone a, the 2 nd to 3 rd service requests are allocated to zone B, the 4 th to 6 th service requests are allocated to zone C, the accumulated number is then cleared, and the cycle is ended, with the next iteration continuing to be repeated. Alternatively, the service request with the cumulative number of the current service requests less than or equal to 2 may be allocated to the area B, the service request with the cumulative number of the previous service requests greater than 2 and less than or equal to 5 may be allocated to the area C, the service request with the cumulative number of the previous service requests greater than 5 and less than or equal to 6 may be allocated to the area B, and then the cumulative number is cleared, and the cycle is ended. It will be appreciated that the first 2 service requests are allocated to zone B, the 3 rd to 5 th service requests are allocated to zone C, the 6 th service request is allocated to zone a, the accumulated number is cleared, and the cycle is ended, and the next time the accumulation is continued again.
In the above embodiment, the number of service requests is counted by determining, so that the service number is distributed proportionally, which is helpful to avoid the situation that some areas are overloaded and other areas are loaded lower, and the load balancing effect of the whole system is improved.
