Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Fig. 2 shows a flowchart of a distributed access service processing method provided in this embodiment, where the method includes:
s201, if a service request sent by an upper layer service is received through a service gateway, analyzing the load condition of each NEA in the current NEA service cluster of the network element adapter through the service gateway, and determining that the service process of the first NEA processes the service request.
The embodiment adopts the idea of soft load and processing stateless, and constructs the access service based on the soft load gateway and the stateless NEA. The access service is mainly composed of a southbound gateway, an NEA service cluster and a service gateway, as shown in fig. 2.
The service gateway is a communication service between an upper layer service and the NEA service cluster, and is responsible for handing downlink requests of the upper layer service calling the NEA to a specific NEA service process according to load balancing conditions, and then returning processing results to the service initiating the requests.
Specifically, after receiving a service request sent by an upper layer service, a service gateway in an access service analyzes the load condition of each NEA in a current network element adapter NEA service cluster, and determines that a suitable service process of a first NEA processes the service request.
The access service is a service between each service of the network management and the network element, and is mainly responsible for protocol conversion and forwarding of messages between the upper layer service of the network management and the network element, and for monitoring and maintaining the link state between the network element and the network management.
And S202, when the service request is processed by the service process of the first NEA and a command needs to be issued to a target network element, sending the command generated by the service process of the first NEA to the target network element through a southbound gateway.
For example, as shown in fig. 3, if the first NEA is NEA1 in fig. 3, the service process of NEA1 processes the service request, generates a command after the processing, and needs to issue the command to the corresponding target network element, the southbound gateway forwards the command to the target network element.
And S203, if the message generated by the target network element according to the command is received through the southbound gateway, analyzing the load condition of each NEA in the current NEA service cluster through the southbound gateway, and determining that the service process of the second NEA processes the message.
The southbound gateway is a soft load gateway realized by adopting a reverse proxy technology, and all network elements communicate with an access service through the southbound gateway which is a unique entrance.
The reverse proxy runs at the server side, and the reverse proxy server receives the client request, then requests resources from other back-end servers and returns the resources to the client. The soft load southbound gateway based on the reverse proxy technology is realized, and the access service is communicated with the network element through the southbound gateway.
The southbound gateway is responsible for shielding processing differences of all network element services, different network elements only need to send messages or requests to the southbound gateway, the southbound gateway is responsible for distribution and scheduling of subsequent processing, and the network elements do not need to care that own messages are processed by the service process. The southbound gateway adopts the soft load idea, and all network elements communicate with the OMC through the gateway, namely the unique entrance. When the network element sends a message to the OMC, the message is firstly sent to the gateway, after the gateway receives the message, the protocol conversion is carried out, and then the message is delivered to an NEA service process in the NEA service cluster for processing according to the load condition.
The NEA service cluster also issues commands through the network elements after the southbound gateway, when the commands need to be issued to the network elements, the NEA service cluster sends the commands to the southbound gateway through remote calling, the southbound gateway can issue the commands to specific network elements, after the processing of the network elements is completed, response results are returned to the southbound gateway, and the southbound gateway sends the results to the NEA service cluster.
And S204, when the message is processed by the service process of the second NEA and the processed data needs to be sent to the upper-layer service, sending the data processed by the service process of the second NEA to the upper-layer service through the service gateway.
The access service completes the communication between the OMC upper layer service and the network element through the coordination work of the southbound gateway, the NEA service cluster and the service gateway.
It should be noted that the gateway is the only entry for the access service to provide the service to the outside, and both the southbound gateway and the service gateway have only one process in the access service, so that only one IP address needs to be configured for the upper layer service and the network element, and the communication with the access service can be realized through the one IP address. The gateway is only responsible for message forwarding and protocol conversion, and the service processing is still completed by the NEA service cluster.
When a plurality of processes simultaneously carry out service processing, the processing efficiency can be effectively improved. And the network elements processed by each service process may be different, so that the problem of strong binding between the processing network elements and the service processes does not exist. When a process fails, the network element data is redistributed according to the current process condition and processed by other processes, thereby ensuring the stability of the system. And when the processing capacity can not meet the service requirement and needs to be expanded, only the NEA process in the service cluster needs to be added, and because the NEA service process processing is stateless, after the process is added, the service processing of the network element can be automatically and uniformly distributed to all current processes for processing, so that the horizontal expansion is easier.
In the embodiment, the access service is composed of the southbound gateway, the NEA service cluster and the service gateway, the message is forwarded between the southbound gateway and the network element, the service gateway executes the communication between the upper layer service and the NEA service cluster, and determines the appropriate NEA for processing according to the load condition of each NEA, so that on one hand, the complexity of manual operation is reduced, on the other hand, the utilization rate of server resources is improved, the uneven busy and idle is avoided, and the probability of problem occurrence under the high load condition is reduced.
Further, on the basis of the above method embodiment, each NEA in the southbound gateway and the NEA service cluster is connected to a distributed cache;
and the southbound gateway and each NEA read data from the distributed cache and store the generated data into the distributed cache.
The distributed cache adopts a distributed lock to ensure atomicity in the data use process.
Specifically, the NEA service cluster is mainly responsible for processing messages reported by the network elements, processing downlink services, and monitoring network element states. The embodiment adopts the idea of separating state data from service processing, modifies the original NEA processing process and realizes the distributed management of the network element. The state Data refers to Stateful Data, is a Stateful object, can store Data, and is non-thread-safe.
In this embodiment, a redis distributed cache is used to store state data separately, and the state data is stripped from an NEA service process, when a service is processed, a network element state does not need to be concerned, and a service processing process can indiscriminately process a received request. As shown in fig. 4, when the state data is related to the service processing process, the state data is obtained from the distributed cache, and is used and updated according to the service condition, and the specific service processing flow is changed accordingly. When processing the uplink message, the NEA service process acquires the state information from the cache according to the specific situation of the request after receiving the uplink message request, updates the cache after the processing is completed, and sends the message to the upper layer service. And (4) downlink request processing, wherein after the NEA service process receives the downlink request, the state information of the corresponding network element is acquired from the cache, the request is subjected to object assembly and conversion, and then a southbound gateway is called to issue a command.
In the embodiment, the service processing and the state data are separated, the state data are separated from the service process, the distributed cache is adopted for storing separately, the atomicity in the data use process is ensured by adopting the distributed lock, a plurality of network elements can be managed in a plurality of processes, and therefore the distributed management of the network elements is realized.
Further, on the basis of the above embodiment of the method, the method further comprises:
s205, in the process of monitoring the link state of each network element through the access service, when a heartbeat cycle starts, each service process in the NEA service cluster acquires network element link data needing heartbeat from the distributed buffer, initiates heartbeat to the corresponding network element according to the acquired network element link data, and updates the network element link data of the heartbeat according to the condition of the heartbeat.
Specifically, in the process of monitoring the link state of the network element, when a heartbeat cycle starts, a service process obtains network element link data that needs heartbeat from a redis distributed cache, and the network element is evenly distributed to each process for processing only. And the service process initiates heartbeat to the network elements according to the acquired network element data, and updates the network element link data of the heartbeat according to the condition of the heartbeat, thereby ensuring the accuracy of the network element link data.
Further, on the basis of the above method embodiment, the service request includes a synchronous request and an asynchronous request;
when the service request is a synchronization request, the first NEA and the second NEA are the same.
In particular, the processing of the service gateway includes synchronous requests and asynchronous requests. When the request is synchronized, the service gateway will wait all the time, and the NEA service will not return the response result of the request until it responds. When asynchronous request occurs, the service gateway ends the call after submitting the request to the NEA service, and returns the response of operation completion to the request service. But the service gateway needs to record the source and the identification of the request, when the NEA business process is processed, the service gateway is called back, the processing result of the request is sent to the service gateway, at this time, the service gateway finds the source of the request according to the request identification in the response, then the response is sent to the current request initiating service, and the whole asynchronous request flow is finished.
The method provided by the embodiment is also suitable for communication processing between the OMC and the base station, and is suitable for most of inter-system communication processing scenes.
Compared with the prior art, when the embodiment manages the network elements, all the network element OM management stations have the same IP configuration, and the configuration is simple; when the access service processes the network element message, the automatic load is allocated to different NEA for processing according to the NEA load, which is beneficial to resource utilization; when one NEA fails, the business processing of the access service is not influenced, and the stability is high; and during capacity expansion, horizontal expansion is automatically carried out without manual intervention.
