Detailed Description

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

The embodiment of the invention provides a network resource reporting method based on a classification serial number, which comprises the following steps:

after receiving the EMS resource change message, the northbound interface respectively delivers the EMS resource change message to each message manager for processing;

and the message manager respectively delivers the processed messages to the adapted message queues according to the sequence of the classified serial numbers.

Preferably, after receiving the EMS resource change message, the northbound interface delivers the EMS resource change message to each message manager for processing, which specifically includes the following steps:

setting a message manager retriever, and inquiring which message managers subscribe the received EM S resource change message through the message manager retriever;

Preferably, each message manager sets a classification serial number for the delivered message, classifies the message, and performs processing on the message as it is or adds the message into a task queue corresponding to the message according to a classification result, which specifically includes the following steps:

Preferably, for a message which does not need to access the database and does not need to block processing, the message is put into another separate task queue to be processed, and the method specifically comprises the following steps:

Preferably, the message manager delivers the processed messages to the adapted message queue according to the sequence of the sorted serial numbers, specifically including the following steps:

Referring to fig. 1, the following describes specific implementation steps of this embodiment with reference to the drawings of the specification.

Step 1, a north interface defines a message manager for each supported north standard;

step 2, after receiving the resource change message from the EMS, the northbound interface delivers the message to each message manager subscribing the message in turn; which message managers the message is subscribed to is maintained by the message manager retriever.

Taking three types of standards such as Common Object Request Broker Architecture (CORBA), multiple-Technology O technologies Systems Interface (MTOSI), and RESTConf, which are supported by the northbound Interface, the northbound Interface defines three message managers to handle message adaptation of the three types of standards respectively. And the northbound interface receives the original message of the EMS for resource change, searches the message managers subscribing the message in the message manager retriever, and delivers the original message to the three message managers if the three message managers subscribe the message.

The following steps 3 to 5 are all the operation flows in a certain message manager, and the operation flows of all the message managers are consistent.

Step 3, the message manager distributes a classification serial number for the delivered message, and the classification serial number is unique under the message manager;

and 4, classifying the delivered messages by a message classifier in the message manager. As shown in fig. 2, the evaluation criteria for the classification are:

(1) whether blocking processing is required;

the original message requiring the blocking process has the highest priority, is processed immediately in the current flow, is not classified into other categories, and is not set up into a task queue. The processing of such messages usually depends on the current snapshot data of the EMS, and needs to interact with the EMS many times to obtain a complete message, and the main thread is blocked in the processing process.

(2) Whether access to the database is required;

the original message that needs to access the database would be placed in a separate task queue. When the message manager processes the messages, the connection of the message manager to the database is kept, and time consumption and instability caused by frequently executing opening/closing of the database connection are avoided.

(3) Whether the data can be placed in the back end for concurrent processing;

raw messages that do not require blocking processing, nor manipulation of the database, are placed in a separate task queue. The message manager sets a thread pool, takes the original message from the task queue, and processes the adaptation of the message in a concurrent manner.

And 5, uniformly delivering the messages processed in the step 4 to the adapted message queue by the message manager. Each message manager has only one adapted message queue.

As shown in fig. 3, because EMS primitive messages are processed concurrently in the message manager, it is necessary to ensure that the order of message delivery into the adapted message queue is consistent with the timing of the primitive messages. The guaranteed time sequence is realized by the classification serial number. The message manager obtains the classification serial number of the message which is matched and is to be delivered, and compares the classification serial number with the classification serial number of the latest message in the matched message queue, and the classification serial number is divided into the following three conditions:

(1) the classification serial number of the current message is larger than that of the message closest to the queue, and the classification serial numbers of the current message and the queue are not adjacent. This indicates that there are still messages that are older than the current message that do not complete the adaptation, so the current message needs to continue waiting until the next delivery cycle.

(2) The classification serial number of the current message is larger than that of the message which is the latest in the queue, and the classification serial numbers of the current message and the queue are adjacent. This indicates that the original message before the current message has been adapted and delivered to the queue, so that the current message can be delivered to the queue.

(3) The classification flow number of the current message is less than the classification flow number of the most recent message in the queue. When the condition is abnormal, a detailed log needs to be recorded, and the current message is inserted into the corresponding position of the queue according to the size of the classification serial number.

After the message manager delivers the processed messages to the adapted message queue uniformly, the messages in the adapted message queue are delivered to the NMS in sequence.

The embodiment of the invention also provides a network resource reporting system based on the classification serial number, which comprises a northbound interface and a message manager, wherein each type of northbound standard supported by the northbound interface corresponds to one message manager respectively;

Preferably, the system further comprises a message manager retriever for: inquiring which message managers subscribe EMS resource change messages received by a northbound interface;

Preferably, the message manager sets a classification serial number for the delivered message, classifies the message, and performs processing on the message as it is or adds the message into a task queue corresponding to the message according to a classification result, and specifically includes the following steps:

Preferably, the message manager puts the message which does not need to access the database and does not need to block processing into another separate task queue to be processed, and specifically includes the following steps:

Preferably, the message manager delivers the processed messages to the adapted message queue according to the sequence of the classification serial numbers, specifically including the following steps:
