Detailed Description
The invention is described in detail below with reference to the drawings and the specific embodiments. It is noted that the aspects described below in connection with the drawings and the specific embodiments are merely exemplary and should not be construed as limiting the scope of the invention in any way.
An embodiment of a dynamic configuration management method for a multi-network area gateway is disclosed herein, and fig. 1 is a flowchart illustrating an embodiment of a dynamic configuration management method for a multi-network area gateway according to the present invention. Referring to fig. 1, the following is a detailed description of each step of the dynamic configuration management method for the multi-network area gateway.
Step S1: and creating corresponding dynamic configuration caches for the gateways in each area in the central control area according to the gateway configuration information of each area.
In this embodiment, in order to implement centralized management and update of gateway dynamic configuration parameters of different areas, a central control area is set, a corresponding dynamic configuration buffer is created at each area gateway in the central control area according to gateway configuration information of each area, and then service clusters in each network area are accessed through the central control area, thereby implementing management of dynamic configuration of the multi-network area gateway. In this embodiment, in order to ensure that each area has a corresponding dynamic configuration buffer in the central control area, before starting the central control area to perform the listening task each time, each area needs to be traversed in a circulating manner, and whether to create a corresponding dynamic configuration buffer for each area is determined. If the fact that the corresponding dynamic configuration cache does not exist in a certain area is detected, the dynamic configuration cache of the area is created and initialized according to gateway configuration information of the area.
Step S2: and calculating the current dynamic configuration parameters of each region at regular time according to the preset timing calculation task.
In this embodiment, after the central control area opens up corresponding dynamic configuration caches for all regional gateways through the step S1, starting to start the monitoring port, and circularly traversing each area according to a preset timing calculation task (for example, once every 5 minutes) to calculate the current dynamic configuration parameters of each region.
Specifically, in this embodiment, in order to save the dynamic configuration parameters of each regional gateway, a configuration parameter structure is set according to the gateway configuration information of each regional gateway, so as to store the dynamic configuration parameters of each regional gateway. The gateway configuration information includes a gateway internal structure and processing logic, and a configuration parameter structure designed according to the gateway configuration information is as follows:
as can be seen from the above table, in this embodiment, the configuration parameter structure includes a primary key, a listener array, a server routing array, an upstream service terminal address, and a unique identification code. Because the gateway dynamic configuration cache under the plurality of areas exists in the central control area, the area name is adopted for unique identification in the embodiment.
When designing the data body of the configuration parameters, the data body of the configuration parameters is divided into 4 components, namely a Listener array (Listener List), a service Route array (Route List), an upstream service array (Cluster List) and a terminal address array (Endpoint List) of the upstream service according to the request processing flow (Listener service- > Route service- > upstream discovery service (upstream service- > service terminal)), by referring to the internal structure and processing logic of the gateway.
In this embodiment, the gateway internal structure includes a monitoring service module, a routing service module, and an upstream discovery service module, and the monitoring service module, the routing service module, and the upstream discovery service module are used to provide four data resources of a corresponding monitoring discovery service, a corresponding routing discovery service, and a corresponding upstream service discovery service, so as to form a data body of the configuration parameter. The monitoring service module is used for receiving the service request of the downstream service and forwarding the received service request to the routing service module for processing. The route service module is used for carrying out upstream service address matching on the received service request and forwarding the matched service request to the upstream discovery service module. And the upstream discovery service module forwards the received service request to the corresponding service terminal according to the upstream service address, so as to realize service calling across network areas.
Further, in this embodiment, the listening service module is configured with a plurality of listeners, each listener corresponds to a port, and the listening service module listens for connection requests of different downstream services through the ports configured by the listeners, and then establishes connection with the corresponding downstream service through the acquired connection request to acquire a service request of the corresponding downstream service. And when the monitoring service module receives the service request of the downstream service through the monitor, filtering the received service request according to a preset access control rule set. If the received service request accords with the access control rule, forwarding the received service request to the routing service module for continuous processing. If the received service request does not accord with the access control rule, intercepting the received service request, and returning error prompt information to the corresponding downstream service.
In this embodiment, after receiving the service request forwarded by the monitoring service module, the routing service module performs search matching according to a preset routing rule, so as to perform upstream service address matching. If the received service request finds a matched routing rule, the matching of the upstream service address is performed according to the matched routing rule, and the matched service request is forwarded to the upstream discovery service module. If the received service request cannot find the matched routing rule, the corresponding service request is not forwarded, and error prompt information is returned to downstream service.
In this embodiment, after receiving the service request forwarded by the routing service module, the upstream discovery service module forwards the received service request to a service terminal in the service terminal list of the upstream service in a load balancing manner. If no service terminal exists in the upstream service, the corresponding service request is not forwarded, and error prompt information is returned to the downstream service.
Therefore, the embodiment designs the data body of the configuration parameters through the gateway internal structure and the processing logic, so as to store the dynamic configuration parameters of each area. In addition, in this embodiment, the dynamic configuration buffer of each region is essentially a memory snapshot, and as the data body changes, the dynamic configuration buffer may change and update at any time. Therefore, a UUID (unique identification code generated based on the current time, counter, and hardware identification (MAC address)) is also required to identify a dynamic configuration cache snapshot of a regional gateway over a period of time.
Step S3: judging whether the local dynamic configuration parameters of the corresponding regional gateway change according to the previous dynamic configuration parameters stored in the dynamic configuration caches of each region; if yes, writing the calculated current dynamic configuration parameters into a dynamic configuration buffer of the corresponding area; if not, continuing to calculate the current dynamic configuration parameters of each region at regular time according to the preset regular time calculation task.
In this embodiment, after the current dynamic configuration parameter is obtained through the calculation in the step S2, the current calculation result is further compared with the previous dynamic configuration parameter stored in the dynamic cache of the corresponding area, so as to determine whether to send the variation. If the current dynamic configuration parameters change, the calculated current dynamic configuration parameters are written into the dynamic configuration buffer of the corresponding area. If the current dynamic configuration parameters of the areas are not changed, the current dynamic configuration parameters of the areas are calculated according to the preset timing calculation task timing.
Step S4: monitoring whether each regional gateway sends a subscription inquiry request; if yes, pushing the calculated current dynamic configuration parameters to the corresponding regional gateway; if not, continuing to monitor whether each regional gateway transmits a subscription inquiry request.
In this embodiment, after the current dynamic configuration parameters obtained by calculation are written into the dynamic configuration buffers of the corresponding areas through the step S3, polling begins to monitor whether the subscription query request sent by the gateway on each area port. And if so, pushing the current dynamic configuration parameters to the corresponding regional gateway for updating. If not, the current dynamic configuration parameters of each area are calculated continuously according to the preset timing calculation task timing.
Specifically, in this embodiment, after the gateway of each area is started, an update gateway configuration buffer is created to store and manage local dynamic configuration parameters of the gateway of each area. The update gateway configuration buffer is connected with the corresponding dynamic configuration buffer in the central control area, and sends a subscription inquiry request to the central control area in a gRPC (global procedure for packet radio service) streaming subscription mode, so that local dynamic configuration parameters are updated.
gRPC is a high-performance and general open source RPC framework issued by Google, is developed based on the bottom HTTP/2 protocol standard and the protocol layer Protobuf serialization protocol, and provides a method for configuring and managing network equipment in support of multiple programming languages. Because the communication is an open source framework, two parties of communication can carry out secondary development, so the communication between the client and the server can be more focused on the content of a service layer, and the attention of the underlying communication realized by the gRPC framework is reduced. The flow of the gRPC request is as follows:
the first step: and writing a definition proto protocol file to respectively generate a client stub and a server skeleton.
And a second step of: the client (gRPC Stub) invokes the A method, initiating the RPC call.
And a third step of: object serialization compression (IDL) is performed on the request information using Protocol Buffer.
Fourth step: after receiving the request, the service end (gRPC Server) decodes the request body, processes the service logic and returns.
Fifth step: object serialization compression (IDL) is performed on the response result using Protocol Buffer.
Sixth step: the client receives the server response and decodes the request body. Callback the called A method, waking up the client call waiting for response (blocking) and returning the response result.
In this embodiment, when pushing the current dynamic configuration parameters to the regional gateway, the central control area needs to determine whether the subscription query request requires full pushing. And if so, pushing the data resources to the corresponding regional gateway by adopting a full-volume pushing mode. If not, adopting an incremental pushing mode to push the data resources to the corresponding regional gateway.
In addition, in this embodiment, when data pushing is performed, data resources of a corresponding type are required to be pushed according to subscription query request types sent by different regional gateways. The subscription query request types comprise a full-quantity independent gRPC flow subscription request, an incremental independent gRPC flow subscription request, a full-quantity aggregate ADS gRPC flow subscription request and an incremental aggregate ADS gRPC flow, and the central control area pushes corresponding data resources to the corresponding regional gateway according to different subscription query request types.
Specifically, in this embodiment, according to the designed configuration parameter structure, the types of data resources subscribed to the query are mainly classified into five types as follows, including: listening Discovery Service (LDS), route Discovery Service (RDS), upstream service discovery service (CDS), discovery service (EDS) of upstream service terminals, and Aggregated Discovery Service (ADS).
As can be seen from the above table, in this embodiment, the subscription query form of each regional gateway is mainly:
1. a full independent gpdc flow for each resource type, for example: full configuration of LDS, RDS, or CDS.
2. Incremental independent gRPC flows for each resource type, such as: incremental configuration of LDS, RDS, or CDS.
3. Aggregate ADS gRPC flows for all resource types, including LDS, RDS, CDS, and aggregate configuration for EDS.
4. Incremental aggregation ADS gRPC streams for all resource types, including LDS, RDS, CDS, and incremental configuration of EDS.
In addition, since the data resources of the ADS type (aggregate discovery service) aggregate LDS, RDS, CDS and the full configuration of EDS, according to the request processing flow (listener service- > route service- > upstream discovery service (upstream service- > service terminal)), in order to prevent uncertainty of arrival timing of the configuration of different data resource types from causing intermittent functional abnormality of the gateway, this embodiment sets a standardized ADS data resource update sequence rule for the ADS type data type:
1. if there is a CDS configuration update, the CDS update must always be pushed first.
2. The EDS configuration must be updated after the corresponding cluster CDS update, if any.
3. The LDS configuration must be updated after the corresponding CDS/EDS update, if any.
4. If the RDS configuration is updated, updating the LDS configuration; at the same time, RDS updates associated with newly added listeners must be completed at the end.
5. And finally, deleting the outdated CDS cluster and the related EDS service terminal.
In this embodiment, after each regional gateway sends a subscription query request to the central control area according to a timed subscription query task (for example, executed once every 5 minutes) to obtain the current dynamic configuration, the obtained current dynamic configuration parameter is compared with the update gateway configuration cache, so as to determine whether to update the local dynamic configuration parameter. And if the received dynamic configuration parameters are compared with the update gateway configuration cache and then change is found, updating the local dynamic configuration parameters. If no change is found after the received dynamic configuration parameters are compared with the updated gateway configuration cache, continuing to send a next round of subscription inquiry request.
In addition, in this embodiment, before updating the dynamic configuration parameters, it is further determined whether the acquired data resource type is an ADS aggregate data type. If yes, writing CDS data, EDS data, LDS data and RDS data into an update gateway configuration buffer in turn according to an ADS data resource update sequence rule, completing real-time effectiveness, and deleting outdated CDS clusters and related EDS service terminals. If not, the configuration data is written into the update gateway configuration buffer memory according to the corresponding data type, and the real-time effectiveness is completed.
