Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
FIG. 1 illustrates a schematic diagram of an implementation environment to which the present application relates, according to an example embodiment. It should be noted that this implementation environment is only an example adapted to the invention and should not be taken as providing any limitation to the scope of use of the invention.
As shown in fig. 1, the implementation environment includes a network access platform 110, an active gateway 120, a standby gateway 130, and a backend server 140.
The network access platform 110 is a system that implements functions such as unified access to multiple networks, forwarding of requests of an external network, and support of automatic load balancing. After various applications access the network access platform 110, the network access platform 110 may provide services to the various applications in a domain name manner, and the network access platform 110 supports network access of various operators.
The background server 140 is a server that receives external data and provides actual business services to the outside. The network addresses used by the active gateway 120 and the standby gateway 130 are recorded in the background server 140, and communication with the active gateway 120 and the standby gateway 130 is performed based on the network addresses.
The primary gateway 120 and the standby gateway 130 are gateway servers, which may be physical servers or virtual servers. In one embodiment, the active gateway 120 and the standby gateway 130 are virtual servers and are deployed on different physical servers, respectively.
The active gateway 120 and the standby gateway 130 both communicate with the background server 140, and the active gateway 120 needs to log in the network access platform when operating. Typically, the external information is sent to the active gateway 120 through the network access platform 110 and forwarded by the active gateway 120 to the background server 140, and vice versa. When the active gateway 120 cannot operate normally due to various reasons such as failure, maintenance, and device update, the standby gateway 130 replaces the active gateway 120 to access the network access platform 110. It should be noted that the accounts used by the active gateway 120 or the standby gateway 130 when accessing the network access platform 110 are the same account, and the network access platform 110 does not allow the two gateways to log on online at the same time by using the same account, so that the standby gateway 130 does not establish a connection with the network access platform 110 when the active gateway 120 operates normally. It should be understood that although only one standby gateway 130 is shown in fig. 1, in other embodiments, there may be two or more standby gateways 130. In addition, the primary gateway 120 and the standby gateway 130 may convert the description of the service roles in which the gateway servers are located when performing the switching, and do not indicate that there is a sequential relationship between the gateway servers. For example, the active gateway 120 may be referred to as a standby gateway 130 after switching to the role of the standby gateway service.
Fig. 2 is a flowchart illustrating a gateway switching method based on a network access platform according to an exemplary embodiment, which may be specifically executed by the standby gateway 130 in the implementation environment shown in fig. 1.
In an exemplary embodiment, as shown in fig. 2, the gateway handover method based on the network access platform at least includes the following steps:
The main gateway and the standby gateway are roles that the gateway server can play, the main gateway refers to a current gateway which provides gateway service, and the standby gateway refers to a redundant gateway which does not provide gateway service and can take over the continuous service of the current gateway. The main gateway and the standby gateway can be mutually converted. And the standby gateway takes over the main gateway to continue service when the main gateway can not normally serve.
The network access platform is a system for realizing the functions of multi-network unified access, external network request forwarding, automatic load balancing support and the like. After the gateway is accessed to the network access platform, the gateway service can be provided for the external request according to the data service provided by the network access platform.
It should be noted that, in this embodiment, the network access platform only allows one gateway to access one login account, so that the gateway accessing the network access platform is referred to as an active gateway, and the access state of the gateway accessing the network access platform is an active state. Correspondingly, at least one gateway which is not accessed to the network access platform is called a standby gateway, and the access state of the gateways which are not accessed to the network access platform is a standby state. The primary gateway may periodically send a status packet to the standby gateway, where the status packet may include information such as a gateway address and a status packet sending time, so as to report a service status to the standby gateway.
It should be noted that, the unique service network address is a virtual network address, and the active gateway or the standby gateway needs to perform access of the gateway access platform through the unique service network address to request the network access platform to acquire data service.
As described above, the first status packet sent by the primary gateway contains the service status of the primary gateway, so that the standby gateway can know whether the primary gateway operates normally, i.e., whether the primary gateway provides gateway service for the outside, according to the first status packet sent by the primary gateway. If the main gateway is abnormal in operation, the standby gateway needs to replace the main gateway to acquire data service from the network access platform, so that a state modification message needs to be sent to the main gateway.
The main gateway switches the self access state from the main state to the standby state according to the indication of the state modification message, and releases the unique service network address for accessing the network access platform, so that the standby gateway accesses the network access platform according to the released unique service network address, and further replaces the abnormal main gateway to continue to acquire data service from the network access platform.
When the main gateway switches the access state from the main state to the standby state, the main gateway stops local gateway service to disconnect the connection with the network access platform, so that other standby gateways use the unique service network address to access the network platform, and the limitation that the network access platform only allows one gateway of the same login account number to acquire data service is realized.
The standby gateway acquires the unique service network address released by the main gateway, and logs in the network access platform by using the account same as the account used by the main gateway according to the unique service network address so as to acquire the data service from the network access platform.
By the method, in the process of switching the main and standby gateways, the service network address for providing the service is not changed, so that background service participation is not needed in the switching process, and the gateway switching operation is automatically completed under the condition that only one gateway is allowed to log in the network access platform for the same account, so that the switching process efficiency is improved, the service non-response time is shortened, and the gateway reliability is improved.
Fig. 3 is a flow diagram of details of step 220 of the corresponding embodiment of fig. 2. In an exemplary embodiment, as shown in FIG. 3, this step 220 includes at least the following steps:
in this embodiment, the active gateway and the standby gateway each have a corresponding priority. The primary gateway adds the priority to the first status packet and sends the first status packet to the standby gateway. And the standby gateway acquires the priority of the main gateway from the received first state message.
The priorities identify how prioritized the gateways are relative to each other. The range of values for the priority may depend on the particular implementation. In one embodiment, the priority ranges from 0 to 255. The available value range is 1 to 254, 0 represents that the corresponding gateway exits from the service, 255 represents that the physical address of the gateway is the same as the unique service network address, that is, the gateway is the default most preferred gateway. In this embodiment, after receiving the first state packet, the standby gateway first reads the priority information in the packet, and if the priority information is greater than 0, it indicates that the active gateway is still in a normal state, and the standby gateway does not start the active/standby switching process and continues to monitor the first state packet.
The standby gateway compares the obtained priority of the main gateway with the local priority of the standby gateway, and if the priority of the standby gateway is higher than the priority of the main gateway, the standby gateway indicates that the service capability of the standby gateway is better than that of the main gateway, for example, the hardware configuration is better, the processing capability is stronger, and the like, so that a state modification message can be sent to the main gateway to start the main-standby switching process.
In one embodiment, when comparing the priorities of the standby gateway and the active gateway, the active gateway priority will have a weighted value to avoid unnecessary active-standby switching. For example, if the priority of the active gateway is 100, the weighting weight is 20, and the weighting manner is addition, the active-standby switching will be performed only if the priority of the standby gateway is greater than 120. Or, if the priority of the active gateway is 100, the weighting coefficient is 103, and the weighting mode is multiplication, the active-standby switching will be performed only if the priority of the standby gateway is greater than 130. The particular manner of weighting and weighting values depend on the particular implementation.
By the method, the active-standby switching can be performed among the gateways according to the service capabilities of the gateways, so that the gateway with higher service capability can provide service preferentially, the gateway with weak service capability is prevented from serving as a main gateway under the condition of larger difference of the gateway capabilities, and the service efficiency is improved.
Fig. 4 is a flowchart of the details of step 220 of the corresponding embodiment of fig. 2. In an exemplary embodiment, as shown in FIG. 4, this step 220 includes at least the following steps:
In this embodiment, after receiving the first status packet sent by the active gateway, the standby gateway records the receiving time. In one embodiment, after the active gateway switches to the standby state, or after the standby gateway is first started, the switching completion time or the start completion time is recorded.
And 224, if the first state message sent by the main gateway is not received within the preset time length, sending a state modification message to the main gateway.
Wherein the standby gateway determines whether a predetermined time period is exceeded based on the recorded reception time. If the standby gateway does not receive the first state message after the recorded receiving time elapses, it may be determined that the primary gateway is in an abnormal state, and then a state modification message is sent to the primary gateway to perform the primary-standby switching. In one embodiment, the standby gateway starts a local timer after recording the time of receipt of the first status message. If the standby gateway fails to receive the first state packet sent by the primary gateway within the preset time length, that is, before the timeout of the timer, the standby gateway may determine that the primary gateway is in an abnormal state and cannot send the first state packet as it is, and further send a state modification packet to the primary gateway, so as to perform the subsequent primary/secondary switching steps.
In one embodiment, if the standby gateway receives the first status packet within a preset time period and the priority information included in the first status packet indicates that the active gateway is in the service state, the standby gateway resets the timer and continues to monitor the first status packet.
By the method, the standby gateway can identify that the main gateway has a fault, and automatically and timely switches the main gateway and the standby gateway, so that the gateway is prevented from being in a non-response state for a long time, and the reliability of the gateway is improved.
Fig. 5 is a flow chart of additional steps of the method of the corresponding embodiment of fig. 2. In an exemplary embodiment, as shown in fig. 5, the gateway handover method based on the network access platform at least includes the following steps:
When the standby gateway is switched from the standby state to the active state, the local priority information is updated at the same time.
Specifically, when the standby gateway is converted into the active gateway, the priority of the standby gateway is simultaneously increased. Accordingly, when the primary gateway is converted into the standby gateway, the priority of the primary gateway is simultaneously reduced. The magnitude of the increase or decrease to the priority may vary depending on the reason for making the state switch. For example, if the standby gateway switches to the active state because the active gateway is in the abnormal state, the priority raising range may be larger, whereas if the priority of the standby gateway is higher than that of the active gateway, or the active gateway actively exits the service, the priority raising range may be smaller, or not raised. Accordingly, if the active gateway is switched to the standby state due to a failure (e.g., a downtime, a hardware failure, etc.), the priority may be greatly reduced, and if the local priority is lower than that of the standby gateway, or the service is actively exited, the priority may be reduced or not reduced by a small degree.
It should be understood that the priority level does not continuously rise or continuously fall, so as to avoid that other gateway servers cannot rob the primary gateway due to too high priority level, or that the gateway servers cannot participate in the handover process due to too low priority level.
It should be understood that although the execution order of the steps is shown in fig. 5, this is only an example and should not be construed as limiting the execution order of the steps in the method proposed by the present application. Where appropriate, the steps of the methods presented herein may be performed in any suitable order.
By the method, the priority of the gateway can be dynamically adjusted according to the specific state and the running condition of each gateway server, and then the main and standby gateways can be switched according to the actual working state of each gateway server, so that the reliability of the scheme is improved.
Fig. 6 is a flow chart of additional steps of the method of the corresponding embodiment of fig. 2. In an exemplary embodiment, as shown in fig. 6, the gateway handover method based on the network access platform at least includes the following steps:
and step 250, acquiring the priority information of other gateways except the main gateway.
In this embodiment, the active gateway has at least two standby gateways. Under the condition that the main gateway fails or actively exits the service and the like, at least two standby gateways send state modification messages to all other gateways, and the state modification messages contain priority information of the corresponding standby gateways. Therefore, in a short time, a plurality of active gateways may exist at the same time. When receiving the state modification message sent by other standby gateways, the standby gateway acquires the priority information in the state modification message and compares the priority information with the local priority.
And step 260, when the priority information indicates that the priority of the standby gateway is the highest, executing the steps of acquiring the unique service network address released by the main gateway and accessing the network access platform according to the unique service network address.
If the priority in the received state modification message is greater than the local priority, the standby gateway will stop the switching process and switch back to the standby state, and monitor the first state message sent by the main gateway. If the priorities in all the received state modification messages are smaller than the local priority, the priority of the standby gateway is the highest of all the standby gateways, the standby gateway acquires the unique service network address released by the main gateway, and the account information used by the main gateway is used for logging in a network access platform.
In one embodiment, all gateways will detect local priority information at startup. If the local priority information indicates that the gateway is the owner of the corresponding real network address of the unique service network address, namely the real network address of the gateway is the same as the unique service network address, the gateway is converted into the main gateway, and other gateways convert the gateway into the standby gateway.
In this embodiment, when there are multiple standby gateways, the priority information of all the standby gateways is obtained and compared, so that the standby gateway with the highest priority is switched to the primary gateway, and the standby gateway with the highest service capability can be ensured to be the primary gateway during switching, thereby ensuring the service efficiency and improving the reliability of the gateway.
Fig. 7 is a flowchart illustrating a gateway switching method based on a network access platform, which may be specifically executed by the active gateway 120 in the implementation environment shown in fig. 1.
In an exemplary embodiment, as shown in fig. 7, the method for switching a gateway based on a network access platform at least includes the following steps:
As mentioned above, the active gateway may periodically send the first status packet to the standby gateway. The standby gateway can acquire whether the main gateway operates normally according to the first state message sent by the main gateway. If the main gateway is abnormal in operation, the standby gateway needs to replace the main gateway to acquire data service from the network access platform, so that a state modification message needs to be sent to the main gateway.
Therefore, when the primary gateway operates abnormally, the primary gateway receives the state modification message sent by the standby gateway.
as described above, the primary gateway or the standby gateway needs to perform access of the gateway access platform through the unique service network address to request the network access platform to acquire data service. Therefore, when the primary gateway operates abnormally and receives the state modification message, the unique service network address needs to be released, so that the standby gateway accesses the network access platform according to the unique service network address, and further takes over the abnormal primary gateway to continue providing gateway service for the outside.
And the main gateway stops the local gateway service in the process of switching to the standby state, so that the standby gateway can log in the network access platform by using the account information same as that of the main gateway. Specifically, the primary gateway may first find whether a gateway process exists. If so, the gateway process is stopped directly.
It should be understood first that the target gateway refers to a standby gateway that switches the access state to the active state, i.e. a new active gateway. Similar to the standby gateway, after the primary gateway is switched to the standby state, the primary gateway monitors a state message sent by the primary gateway and starts a local timer to detect whether the standby gateway is in a normal service state.
In one embodiment, the server of the main gateway is restarted due to a downtime or a network connection failure, and in fact, after the main gateway is restarted, whether the main gateway which is in service exists or not is detected, and if the main gateway exists, the main gateway directly enters a standby state.
In this embodiment, the active gateway responds to the state modification packet of the standby gateway, releases the unique service network address and stops acquiring the data service, and starts monitoring a new state packet sent by the active gateway.
By the method, in the process of switching the main and standby gateways, the service network address for providing the service is not changed, so that background service participation is not needed in the switching process, and the gateway switching operation is automatically completed under the condition that only one gateway is allowed to log in the network access platform for the same account, so that the switching process efficiency is improved, the service non-response time is shortened, and the gateway reliability is improved.

The updating module 440 is configured to switch the access state of the standby gateway from the standby state to the active state, and update the priority information locally stored in the standby gateway.
