Detailed ways

Below in conjunction with specific embodiment the present invention is described in further detail:

A managed object is an abstract entity used to represent a specific network resource for the purpose of network management and can be accessed by several systems through an open interface. It is an instance of the managed object class defined in the management information model, for example: "represents office direction object to Beijing", "single board object representing a board with 1 rack and 3 slots", etc.

The property of the managed object is a quantity that describes a certain property of the managed object, such as: "office name of the office object", "frame number and slot number of the board object", etc.

Managed object operations are operations that can be performed on managed objects, such as "delete office route" and "delete board". Generally speaking, the operation of the managed object is the same for all instances of the managed object class, and the parameters required by the operation are also the same, but the parameter values of the operation are different.

The maintenance and measurement operation is an operation on the managed object. From the perspective of the characteristics of the maintenance and measurement operation, the process of most maintenance and measurement operations is relatively uniform and fixed, that is, the maintenance and measurement module (request side) sends the request to The managed object (response side), and receives the response given by the managed object according to the request. There are three most typical maintenance and measurement operation procedures:

1. One request one response mode

This method is the most commonly used method. In this method, the object of the operation of dimensional measurement is single and fixed. The maintenance and measurement module sends a request to a managed object, and the managed object responds to the request.

2. One request and multiple responses

In this way, there is one managed object for the operation of the maintenance test, but there are multiple managed objects responding to the request, which are sent back in frames.

3. Multiple requests and multiple responses

This method means that there are multiple managed objects for a maintenance and measurement operation, and the maintenance and measurement module will distribute command frames according to the managed objects, and then centrally collect and process the responses of each managed object.

For these three typical maintenance and measurement operation processes, the content of the sending request is the format and content of the sending frame, as well as the destination of the sending, which are the information that must be collected for the maintenance and testing operation. These three maintenance and measurement operation processes can be described, and each operation process can be decomposed into two most basic processing operations except task logic: one is frame sending processing, and the other is frame receiving processing. The process of sending frames is that the maintenance module generates a sending frame according to each parameter of the managed object operation, and then sends it to the managed object of the host for execution; the process of receiving frames is that the maintenance module receives the operation of a managed object from the host Return the frame, and give the execution result according to the content of the returned frame.

In order to be able to realize the general processing of maintenance and measurement operation, the steps of the present invention are as follows:

Step 1. Model the object of the maintenance and measurement operation (i.e. the managed object), abstract each attribute of the object into the attribute of the managed object, and abstract the operations of the object and the parameters of the operation into the operation of the managed object. In this way, for each A managed object has a unique set of management methods, that is, to manage all attributes and operations of each managed object.

Taking the board object as an example to model, 1) the attributes of the board object include the board number and board type; 2) the operation of the board can include adding, modifying, deleting, and resetting, and the operating parameters of the newly added operation Including the board number and board type, the operation parameter of the modify operation is the board type, and the operation parameter of the delete operation and reset operation is the board number.

The present invention manages the single board object, only needs to manage its two attributes and four operations, in the object model of the present invention, each object class (such as single board, chassis, etc., is an object class) has A unique object class number. For example, the object class number of a board is 1; attributes also have numbers, and the numbering method is a unified number within the object class. For example, attribute 1 of a board is the board number, and attribute 2 is the board type; operations also have Numbering, the numbering method is also a unified numbering within the object class. For example, operation 1 of a single board is to add, and operation 2 is to modify; the operation parameters of each operation are also numbered. For example, in operation 1 of a single board (add operation), the operation parameter is single Attribute 1 and attribute 2 of the board class, so that an object is managed.

The operation after object modeling is very vivid, and it is an operation for a certain object. For example, after modeling, there are several clear operations for the maintenance and testing of a single board: add, modify, delete, and reset. If there is no object modeling process, the maintenance and testing of the board may be scattered four operations: adding a board, modifying a board, deleting a board, and resetting a board. The maintenance and testing personnel have no way of knowing what can be done on a board. operate.

According to the description of the typical process of the maintenance and inspection operation above, reset is a typical maintenance and inspection operation of the board object. The user enters the board number of the board to be reset, and a reset request is sent to the board object. After receiving the request, the board object performs a reset operation, and returns a result frame to the user after the reset is successful, indicating that the reset is successful.

Step 2, define unified transmission frame generation and description rules and reception frame description and interpretation rules; use the above rules to describe each The sending frame processing method and receiving frame processing method corresponding to the maintenance and measurement operation of the managed object; the maintenance and measurement module finds the corresponding description according to the required maintenance and measurement operation, and then performs operations according to the description, so that the general processing of the maintenance and measurement operation can be completed.

The specific rule definition is given below, and continue to explain by taking the board reset operation as an example:

Sub-step 1. Use natural language to describe each measurement operation of the managed object. The description includes:

1) The managed object operation identifier is used to uniquely identify a type of maintenance and measurement operation: assuming that the unique identifier of the single-board object reset operation is defined as 1, it is not a query operation;

2) The unique identifier of the sending side of the operation: suppose the identifier is the number 2001;

3) The unique identifier of the receiving side of the operation: suppose the identifier is the number 3001;

4) The address of the processing method corresponding to the request side: Assume that it is a stored procedure named BoardResetRequestSend (board reset request sending processing) in the database, and the stored procedure has a parameter board ID;

5) Address of the processing method corresponding to the response side: it is assumed to be a stored procedure named BoardResetResultReceive (board reset result processing) in the database.

Sub-step 2, the sending frame structure and the returning frame structure are described in a natural language, and the content of the description is as follows:

1) Managed object operation identifier, which is used to uniquely identify a type of maintenance and measurement operation;

2) The type and length of each field in the frame;

3) Sending frame structure at the request side: if the managed object operation identifier is 1, the sending frame structure is a one-byte numerical type (for example, the attribute length of the single board number is a one-byte numerical type);

4) The response side returns the frame structure: if the managed object operation flag is 1, the returned frame structure is also a one-byte numeric value;

5) The description method of sending frame and receiving frame is the same, using the same set of rules.

Sub-step 3. The processing method on the request side is described in natural language, and the content of the description includes:

1) The request side generates a transmission frame.

Generate the following sending frame according to the input board ID in the address of the BoardResetRequestSend processing method:

Struct

{

BYTE iProcID;//Store the managed object operation ID 1

BYTE iBrdID;//store the board number specified by the user

}

Sub-step 4. The processing method on the response side is described in natural language, and the description includes:

1) For non-query operations, the returned content only includes the operation result code, and the response side interprets the meaning of each operation result code described in advance;

2) For query operations, the returned content is each attribute of the managed object, which can be explained according to the description of the managed object, and the query result of the managed object is given;

The operation result codes of non-query operations need to be defined in advance, for example, 0 indicates that the reset is successful, and 1 indicates that the reset fails.

Board reset is a non-query operation, and the returned content only includes the operation result code, for example:

Struct

{

BYTE by Result;

}

After describing the sending frame processing method and receiving frame processing method corresponding to the maintenance and measurement operation of each managed object in natural language according to the above rules, the specific process of using the method of the present invention to realize the single board reset operation can be given:

1), the user executes an operation whose operation identifier is 1 for the managed object;

2) The maintenance and measurement system searches all operations of the system described in natural language according to this unique identifier, and can obtain the unique identifier of the sending side as 2001, and finds the request side processing method BoardResetRequestSend according to this unique identifier;

3), the Board ResetRequestSend method generates a request side send frame, and sends it to the host for operation;

4), receive a response message, the unique identifier of the message is 1, it can be known that it is a response message of an operation whose operation identifier is 1 for the managed object;

5) The maintenance and measurement system searches all operations of the system described in natural language according to this unique identifier, and can obtain the unique identifier of the response side as 3001, and find the response side processing method BoardResetResultReceive according to this unique identifier;

6) The BoardResetResultReceive method performs response side processing, and the operation result code is 0. According to the definition of the operation result code, 0 means that the reset is successful, and the reset success is displayed to the user.

In order to realize the automatic maintenance of the network, for all the maintenance and inspection operations of the managed objects, timers can be registered in the system, and the values of operation parameters can be defined at the same time, and the maintenance and inspection operations can be triggered uniformly by the timers. Still taking the board reset and maintenance operation as an example, as long as the object class number, object operation number and operation attribute value are given (for the board reset operation, it is the board number), define an execution time of the operation (you can It can be a fixed time, or it can be a period, such as three o'clock in the morning every day), the timer is bound to a certain maintenance and testing operation (such as resetting the board), and the automatic maintenance and testing can be completed by triggering the timer Operation, that is, to realize the maintenance and inspection operation of resetting a certain board at regular intervals, for example, resetting a certain board at 3 o'clock in the morning every day.

The method provided by the present invention is used to carry out maintenance and measurement operations on the network. Through the method of object modeling and definition of maintenance and measurement operations, a unified process of maintenance and measurement operations is defined for the main characteristics of maintenance and measurement operations, and the same set of operation rules can be used to complete all maintenance and measurement operations. test operation. After the automatic maintenance and inspection is realized, the operator does not need to arrange special personnel to be responsible for the maintenance and inspection operation, which saves labor costs. At the same time, the automatic maintenance and inspection operation also greatly avoids the misoperation caused by manual operation.

Those skilled in the art do not depart from the essence and spirit of the present invention, there can be many variants to realize the present invention, the above description is only a preferred and feasible embodiment of the present invention, and it does not limit the scope of rights of the present invention.
