[0049] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

[0050] The term "including" and its variations used herein are open inclusions, i.e., "including but not limited to". The term "based on" means "based at least in part on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description.

[0051] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0052] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0053] Normally, the application system is deployed on the server as a complete computer program, and the computer program is run on the server to realize the business processing of the received user access traffic. If the departure system needs to be upgraded, the complete computer program needs to be upgraded. During this process, the operation of the application system has to be interrupted until each functional module of the computer program is upgraded. Only then can it be re-run to obtain the upgraded application system. For application systems with timeliness or large access traffic, it will affect the user experience and the efficiency of business processing.

[0054] In order to solve the above problems, this application proposes a departure system upgrade method, which is applied to a server where the departure system is deployed. Figure 1 , an example diagram of the business partition deployment of the server provided in an embodiment of the present application.

[0055] The server is deployed with a partition group corresponding to each preset area determined by the departure system according to the preset area division rules, and each partition group contains at least two business partitions, which can perform departure business processing on the user access traffic corresponding to the preset area. Figure 1 A1, A2, B1, B2...F1, F2 are business partitions, and each business partition can process user access traffic. Among them, business partitions B1 and B2 belong to two business partitions corresponding to the same preset area, that is, they belong to the same partition group and can perform the same processing function on user access traffic.

[0056] Optionally, multiple microservices can be deployed on each business partition. Microservices (or microservice architecture) is a cloud-native architecture approach that includes many loosely coupled and independently deployable small components or services in a single application. Microservices work together to complete the corresponding processing functions. For example, the departure system in the Asian region needs to implement other services while implementing basic departure services. In this way, multiple microservices can be deployed on the business partition corresponding to the Asian region, so that the business partition in the Asian region can be separated from the departure business functions of other regions.

[0057] In the embodiment of the present application, service partitions are deployed according to different processing objects, and at least two service partitions with the same processing objects are grouped as a partition. It is understandable that the departure rules of airports in each region are different. For example, the departure rules and departure rule file formats in Asia and America are different. If the same departure system is used, there may be problems such as format compatibility. Therefore, in the embodiment of the present application, the server deploys service partitions corresponding to different regions to implement departure services, and obtains a partition group corresponding to each region. Figure 1 The flight departure system needs to handle departure requests from multiple regions such as Asia and America. Business partitions A1 and A2 can be deployed for Asia. Business partitions A1 and A2 only handle user access traffic from Asia. Business partitions B1 and B2 can be deployed for America. Business partitions B1 and B2 only handle user access traffic from America, and so on. I will not go into details here.

[0058] Furthermore, when the server receives an upgrade request for the outbound system to the target version, the upgrade process for each partition group can refer to Figure 2 , a flow chart of a method for implementing a departure system upgrade provided in an embodiment of the present application, the specific steps may include the following contents.

[0059] It should be noted that the upgrade request received by the server can be the upgrade request sent by the operation and maintenance personnel through the front end and the corresponding configuration file update, start and stop background service, manual test service and other instructions, or it can be the server automatically monitoring the existence of an upgrade data packet in the departure system, which serves as a signal that there is an upgrade demand. The server responds to the signal and executes the departure system upgrade method below.

[0060] Step S110, determining the type of user access traffic processed by each service partition in the partition group.

[0061] Step S120: classify each service partition according to the type of user access traffic processed by each service partition to obtain a first partition and a second partition.

[0062] Reference Figure 3 , an application example diagram of a server for deploying a flight departure system provided in an embodiment of the present application, the server will receive user access traffic sent by the front end, external system, etc. The departure system in the server distributes the user access traffic to each business partition based on the area and airport to which each user access traffic belongs.

[0063] In an embodiment of the present application, it is assumed that there are three business partitions in a partition group, such as the verification zone, the general zone and the blank zone in the figure. In the figure, D1, DC, etc. are microservices deployed on the business partitions. The deployment of multiple microservices enables the business partitions to realize departure services. The traffic proportion of user access traffic allocated to one of the business partitions is zero, preparing for the subsequent uninterrupted upgrade of zero traffic. The remaining two partitions can allocate all received user access traffic in any proportion, but usually the business partition with a higher system version in the remaining two partitions is used as the main partition to handle a larger proportion of user access traffic, provide higher version services for most users, and improve user experience.

[0064] Therefore, the functional unit for allocating user access traffic in the server can monitor the traffic proportion of user access traffic allocated to each business partition in real time. Alternatively, the server can obtain the partition status table of the departure system, which stores information such as the system version, last upgrade time, and traffic proportion of user access traffic processed by each business partition after the last upgrade is completed; query the partition status table to determine the traffic proportion of user access traffic processed by at least two business partitions included in the currently upgraded partition group.

[0065] The embodiment of the present application takes into account that if the user access traffic is divided only according to the ratio, it is very likely that the abnormal processing of a departure business at an airport with a large user access traffic will cause chaos in the overall departure business of the airport. Because the embodiment of the present application uses the airport as the traffic division unit, the user access traffic is classified for upgrade, verification and normal business processing respectively. For example, airports with large traffic such as Baiyun Airport and Beijing Airport are listed as the first batch of preset airports, and the user access traffic of the first batch of preset airports is only processed by the upgraded and stable business partitions; some airports with small user access traffic are listed as the second batch of preset airports, and the user access traffic of the second batch of preset airports is used to verify the upgraded business partitions, reducing the impact on the airport departure business during the verification process. Among all the user access traffic in the area corresponding to the partition group, the proportion of user access traffic at the first batch of preset airports is much greater than the proportion of user access traffic at the second batch of preset airports.

[0066] Optionally, if the embodiment of the present application does not consider the verification of the upgraded departure system, it is only necessary to treat the user access traffic of all airports as the second type of user access traffic, that is, the business partition with a user access traffic proportion of 100% is the second partition.

[0067] After each upgrade, the server will record the partition information of each business partition, such as the traffic proportion of the processed user access traffic, the airport to which the user access traffic belongs, the current version information, the time when the update was completed, the partition identification, etc. This is convenient for operation and maintenance personnel to troubleshoot problems when there are problems in the upgrade or operation of the application system.

[0068] Optionally, when the server records the status of each business partition in real time, obtain the partition status table used to record the status of the business partition, and query the airport to which the user access traffic assigned to each business partition belongs when the last upgrade was completed, so as to determine the type of user access traffic handled by each business partition.

[0069] It is also possible to count the proportion of user access traffic processed by each business partition, and use the business partition with zero traffic proportion as the first partition for subsequent system upgrades. Since the user access traffic processed by the first partition is zero, the subsequent upgrade will not affect the normal processing of user access traffic by other partitions. Moreover, if the first partition encounters an operation error during the upgrade process, since each partition is independent of each other, it will not affect the normal operation of other partitions. Based on the above situation, upgrading the first partition can achieve upgrades without interrupting the application system.

[0070] While determining the first partition, it is also necessary to determine the second partition that processes the largest proportion of user access traffic in the partition group, so that after the subsequent upgrade is successful, the user access traffic of the second partition can be allocated to the upgraded partition.

[0071] Step S130, upgrading the system version of the first partition to the target version to obtain an upgraded first partition.

[0072] Step S140: distribute the second type of user access traffic processed by the second partition to the upgraded first partition that meets the preset conditions.

[0073] Reference Figure 4, a schematic diagram of the business partition upgrade process provided in an embodiment of the present application, taking a partition group including two business partitions A1 and A2 as an example, after the last upgrade was completed, partition A1 had the highest system version, and processed 100% of the user access traffic, that is, the first batch of preset airports, that is, all airports in the preset area, then in this upgrade, partition A2 with a traffic share of 0 is upgraded as the first partition. The system version of A2 is upgraded to the target version 1.3, which is the latest version. After the upgrade of the first partition A2 is completed, 100% of the user access traffic is diverted to A2, so that users can use the latest version of the application system. In an embodiment of the present application, "version" is a logical concept. Whenever the software service within a partition is updated, the "version" of the partition changes, and is refreshed as the update time changes. The larger the version value, the newer the update time.

[0074] In summary, the departure system to be upgraded in the present application is deployed with a partition group corresponding to each area, each partition group includes at least two business partitions, and the business partition can process the user access traffic for departure business, so that the upgrade of each departure area business will not affect each other. When upgrading the departure system, first classify each business partition in the partition group, and upgrade the business partition with zero user access traffic as the first partition, without affecting the normal operation of other business partitions with user access traffic processing needs. After the upgrade of the first partition is completed, the user access traffic of the airport is allocated to the upgraded first partition, and the upgraded departure system is used to process the user access traffic. The upgrade task of the departure system is completed without interrupting the processing of the user access traffic by the departure system, and the upgrade is carried out by dividing the business groups by region. Compared with the overall upgrade of the departure system, the upgrade efficiency of the departure system can be improved.

[0075] Next, other possible implementations of the above departure system upgrade method are described.

[0076] In an embodiment of the present application, allocating user access traffic to the upgraded first partition also requires a prerequisite, that is, the upgraded first partition meets the preset conditions, which may include: no upgrade errors occur during the upgrade process, the upgraded first partition can handle user access traffic normally, and other conditions, which can be set according to the needs of the operation and maintenance personnel.

[0077] Optionally, the embodiment of the present application takes the preset condition that the upgraded first partition can handle user access traffic normally, so it is necessary to pre-introduce a small amount of user access traffic to detect whether the upgraded first partition can handle it normally, so as to determine whether to use the upgraded first partition as the main partition and allocate the user access traffic with the largest traffic proportion.

[0078] by Figure 4As shown, when the partition group where the upgraded first partition A2 is located has only two business partitions, the user access traffic with a preset traffic proportion can be allocated to the upgraded first partition; detect whether there is any abnormality in the processing of the user access traffic by the upgraded first partition within the preset time; when there is no abnormality in the processing of the user access traffic by the upgraded first partition within the preset time, it is determined that the upgraded first partition meets the preset conditions, and user access traffic is allocated to the upgraded first partition until the traffic proportion of the user access traffic processed by the upgraded first partition reaches the maximum traffic proportion.

[0079] From the user access traffic processed by A1, the user access traffic with a preset traffic percentage is extracted. The user access traffic with the preset traffic percentage is used to detect the processing capacity of A2. The preset traffic percentage can be as small as possible, such as 20%, to minimize the impact range when A2 has an operation error.

[0080] 20% of the user access traffic in A1 is allocated to the upgraded A2 for verification. Within the preset time, the upgraded A2 handles 20% of the user access traffic to see if there are any errors or abnormal processing results. If there are no abnormalities, it proves that the upgraded A2 can handle the user access traffic normally. The remaining 80% of the user access traffic is allocated to the upgraded A2, so that all users can experience the updated application system and improve the user experience.

[0081] In the case where the partition group contains three of the business partitions, the process of verifying and allocating user access traffic to the upgraded first partition may include: determining a third partition in the partition group, the third partition being a business partition that processes a third type of user access traffic, the third type being user access traffic of a second batch of preset airports used to verify the upgraded departure business processing capability; the sum of the user access traffic of the first batch of preset airports and the second batch of preset airports being all user access traffic within the preset area corresponding to the partition group; allocating the user access traffic processed by the third partition to the upgraded first partition; detecting whether there is any abnormality in the processing of user access traffic by the upgraded first partition within a preset time; and determining that the upgraded first partition meets the preset conditions and allocating the first type of user access traffic processed by the second partition to the upgraded first partition if there is no abnormality in the processing of user access traffic by the upgraded first partition within the preset time.

[0082] Referring to the instructions corresponding to steps S110 and S120, the airports in the preset area are divided into two batches according to the scale of the airports and the purpose of the user access traffic. The user access traffic of the first batch of preset airports is processed by the high-version business partition, and the user access traffic of the second batch of preset airports is used to verify the processing capacity of the business partition that has just been upgraded. Among them, the proportion of user access traffic of the first batch of preset airports is much larger than that of the second batch of preset airports. For example, the user access traffic of the first batch of preset airports is 80% of all user access traffic in the preset area, and the remaining 20% ​​is the user access traffic of the second batch of preset airports.

[0083] Optional, see Figure 5 , an example diagram of an upgrade of a service partition provided in an embodiment of the present application, in which "one" in each table of a, b, c, and d in the figure represents the first partition, "two" represents the second partition, and "three" represents the third partition, and the second column is the version number corresponding to each partition. In order to verify whether the upgraded first partition can normally handle user access traffic, the embodiment of the present application deploys three service partitions in each partition group when deploying service partitions, including: a blank area, a common area, and a verification area. The first partition, the second partition, and the third partition are determined by identifying the traffic proportion of the user access traffic of each partition. Among them, the blank area is a service partition with a traffic proportion of zero, which is used for no-traffic upgrade and can be determined as the first partition; the verification area is a partition for verifying the processing capacity of user access traffic, which is used to process the user access traffic of the second batch of preset airports, and the traffic proportion is greater than zero and less than the maximum traffic proportion, which can be determined as the second partition; the common area is used to process the user access traffic of the first batch of preset airports, and the traffic proportion of the user access traffic is the service partition with the maximum traffic proportion, which can be used as the third partition.

[0084] First, upgrade the first partition to obtain the first partition with version 1.3, complete the upgrade, and obtain Table b. Further, verify the first partition with version 1.3. The server can use the traffic allocation tool to achieve "one-click switching" between the user access traffic of the second partition and the user access traffic of the first partition, complete the unified transfer of traffic within a fixed time, and uniformly allocate the user access traffic of the second partition to the upgraded first partition, and obtain Figure 5 It can be understood that "one, two, three" in Table c represent the traffic or traffic type corresponding to each partition, that is, "two" in Table c represents the business partition whose traffic type is the user access traffic of the second batch of preset airports.

[0085] If no exception occurs in the processing of user access traffic during the partition verification of version 1.3, the user access traffic of the third partition (or "ordinary zone") is converted to the partition of version 1.3 through "one-click conversion" of user access traffic, thereby realizing the version upgrade of the main partition.

[0086] It can be understood that the upgrade and verification of the partition is completed by switching the user access traffic. After the upgrade is completed, the second type of user access traffic used for verification is switched to the business partition with a newer version. If during the switching process, the second type of user access traffic is left in the blank area with the lowest version, refer to the steps below to switch the second type of user access traffic to a business partition with a higher update level compared to the blank area, so as to avoid the second type of user access traffic being unable to be processed by the updated system when there is no upgrade demand. Specifically, it includes: comparing the version update level of the current version corresponding to the second partition and the third partition, determining the business partition with a higher version update level and the business partition with a lower version update level in the second partition and the third partition; allocating the third type of user access traffic processed by the upgraded first partition to the business partition with a higher version update level.

[0087] As can be seen from the above, a preset time is required to verify the processing capacity of the first partition after the upgrade for user access traffic. In the embodiment of the present application, the preset time is the time period from this upgrade to the next upgrade. It can be seen from Table a that after the last upgrade, the partition of version 1.2 has always been a verification zone. Therefore, at the beginning of this upgrade, the verification time of the partition of version 1.2 meets the preset time. If there is no abnormality in the user access traffic of the partition of version 1.2, the user access traffic of the third partition is "switched with one key" with the user access traffic of the partition of version 1.2, so as to realize the upgrade of the main partition. In the next upgrade, the partition of version 1.3 is "switched with one key" with the user access traffic of the third partition at that time, so as to upgrade the main partition to version 1.3.

[0088] However, if the preset time does not need to wait until the next upgrade, the user access traffic of the third partition and the user access traffic of the partition of version 1.3 can be "switched with one click" when the verification time reaches the preset time.

[0089] In summary, the embodiments of the present application can verify the user access traffic processing capability of the upgraded first partition by allocating user access traffic between partitions, thereby reducing the probability of system errors after the upgrade.

[0090] Optionally, the embodiment of the present application may also allocate and verify only based on the proportion of user access traffic without considering the impact of verification failure on airport business. For example, the traffic proportions of the first partition, the second partition, and the third partition are 0, 10%, and 90%, respectively. During verification, the traffic proportion of the first partition is 10%, the traffic proportion of the second partition is 0, and the traffic proportion of the third partition is 90%. When the "one-key switching" function is not available, 80% of the user access traffic can be retrieved from the 90% user access traffic and allocated to the first partition, so that the traffic proportion of the first partition reaches 90%, and the upgrade of the main partition is realized. In this case, there is still 10% of the user access traffic in the partition that is not the latest version. In order to improve the user experience of this part of users, 10% of the user access traffic can also be allocated to the upgraded first partition.

[0091] However, in order to ensure that the verification partition has user access traffic for verification during the next upgrade, 10% of the user access traffic needs to be separated from the upgraded first partition. At the same time, in order to improve the processing capability of this 10% of user access traffic, the version update levels of the current versions corresponding to the third partition and the second partition can be compared. In the third partition and the second partition, the business partitions with a higher version update level and the business partitions with a lower version update level can be determined; the remaining user access traffic of the third partition is allocated to the business partition with a higher version update level, so that the traffic proportion of the user access traffic processed by the business partition with a lower version update level is zero.

[0092] A partition with a higher version is determined between the second and third partitions to handle the remaining 10% of user access traffic, so as to improve the experience of these 10% of users on the departure system as much as possible. The user access traffic of the partition with a lower version is cleared to zero, so that in the next upgrade, there can be a first partition for zero-traffic upgrade among the three business partitions.

[0093] Under normal circumstances, the application system will continuously update its version and constantly change the traffic proportion of different business partitions. However, when there is an abnormality in the processing of user access traffic by the upgraded first partition, the upgraded first partition is repaired to obtain a repaired first partition; if there is an abnormality in the processing of user access traffic by the repaired first partition, the repaired first partition is rolled back to the initial version of the first partition, and the initial version is the system version before the first partition is upgraded.

[0094] Reference Figure 4Whether in the verification process or in the process where the 1.3 version of A2 has become the primary partition and processes 100% of the user access traffic, as long as A2 processes the user access traffic abnormally, A2 will be repaired first. If the repaired A2 processes the user access traffic no longer abnormally, the subsequent steps will be performed based on the repaired A2. If the repaired A2 still processes the user access traffic abnormally, the 1.3 version of A2 will be rolled back to the 1.1 version, with priority given to ensuring that there are no abnormalities in the processing of user access traffic, and then considering whether the partition version is the latest version.

[0095] Alternatively, when there is an abnormality in the processing of user access traffic by the upgraded first partition, the user access traffic currently processed by the upgraded first partition is allocated to the second partition or the business partition with the largest traffic proportion.

[0096] If the rollback still fails to resolve the abnormality in A2's processing of user access traffic, you can consider diverting the user access traffic to a partition without abnormalities. Alternatively, after discovering the abnormality, instead of repairing or rolling back, you can directly switch partitions to avoid abnormalities in the processing of user access traffic.

[0097] Optionally, the above-mentioned measures adopted for the upgraded first partition with abnormal traffic processing may also be applied to any other partitions to avoid abnormal processing of user access traffic by other partitions and improve user experience.
