The above and other features and advantages of the present invention will become more apparent to those skilled in the <

The present invention will be further described in detail below in conjunction with specific embodiments:

The managed object is an abstract entity used for network management purposes to represent a specific network resource 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: The object of the office to the office in Beijing, "the board object of the board that represents the slot of the 3 slots," and so on.

The managed object attribute is an amount that describes a certain property of the managed object, such as: "the office direction name of the office office object", "the frame number of the board object, and the slot number". The managed object operation is an operation that can be performed on the managed object, such as: "delete office direction", "delete board", and so on. In general, the operation of the managed object is the same for all instances of the managed object class, and the parameters required for the operation are the same, except that the parameter values of the operation are different.

The dimension measurement operation is an operation performed on the managed object. From the characteristics of the dimension measurement operation, the flow of most of the dimension measurement operations is relatively uniform and fixed, that is, the dimension measurement module (sending side) transmits the request to the The managed object (receiving side), and receives the response given by the managed object according to the request. The most typical dimensional operation procedures are three:

1, a request and a response method

This method is the most common way, in which the object of the dimensioning operation is single and fixed. The dimension measurement module delivers the request to a managed object, and the managed object responds to the request.

2, a request for multiple response methods

In this mode, the managed object of the dimensioning operation is one, but the managed object responds to the request by multiple, and is sent back in frames.

3, multiple request multiple response mode

This method refers to a plurality of managed objects of a dimension measurement operation, and the dimension measurement module performs command frame distribution according to the managed object, and then collectively collects responses of the respective managed objects.

For these three typical dimensional operation procedures, the content of the transmission request is the format and content of the transmission frame, and the destination of the transmission. These are the information that the measurement operation must collect. These three kinds of dimensional operation flow are descriptive. Each operation flow removal task logic can be decomposed into two basic processing operations: one is the frame processing and the other is the frame processing. The process of the frame sending process is that the dimension testing 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 to execute; the process of receiving the frame is that the dimension measuring module receives the host to operate on a managed object. The frame is returned, and the execution result is given according to the content of the returned frame. In order to enable the general processing of the dimensioning operation, according to the first embodiment of the present invention, the performing the dimensioning operation may include the following steps:

Step 1. Model the object of the dimensioning operation (ie, the managed object), abstract each attribute of the object into the attribute of the managed object, and abstract the parameters of the operations and operations of the object into managed objects, so that for each A managed object has a unique set of management methods that manage all the properties and operations of each managed object.

The board object is used as an example for modeling. 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 operation parameters of the new operation. The board parameters are the board type. The operation parameters of the modify operation are the board type. The operation parameters of the delete operation and the reset operation are the board numbers.

The present invention manages a single-board object, and only needs to manage its two attributes and four operations. In the object model of the present invention, each object class (for example, a single board, a chassis, etc., is an object class) A unique object class number, for example, the object class number of the board is 1; the attribute is also numbered, and the numbering mode is a uniform number in the object class. For example, attribute 1 of the board is the board number, and attribute 2 is the board type. The numbering and numbering methods are also uniformly numbered in the object class. For example, the operation 1 of the board is increased, and the operation 2 is modified. The operation parameters of each operation are also numbered, for example, the operation of the board 1 (increase operation), and the operation parameters are single. The attribute 1 and attribute 2 of the board class, so that an object of 4 bar is managed.

After the object is modeled, the operation is very visual. It is an operation for an object. For example, the modeling of a board after modeling has several clear operations: add, modify, delete, reset. If there is no object modeling process, the maintenance of the board may be the four operations of the board: adding a board, modifying a board, deleting a board, and resetting a board. The wireless tester has no way of knowing which one board can be used. operating.

According to the above description of the typical flow of the test operation, the reset is a typical operation of the board object. The user inputs the board number of the board to be reset, and a reset request is received. The board object is sent to the board object. After receiving the request, the board object performs a reset operation. After the reset is successful, a result frame is returned to the user to indicate that the reset is successful.

Step 2: Define a unified transmission frame generation and description rule and return frame description and interpretation rules; use the above rules to describe each language in a programming language (which may be in a natural language such as Extensible Markup Language XML or Structured Database Query Language SQL) The transmission frame processing method and the return frame processing method corresponding to the dimension object operation of the managed object; the dimension measurement module finds the corresponding description according to the required dimension measurement operation, and then operates according to the description, so that the general processing of the dimension measurement operation can be completed.

The following is a specific rule definition, and continues to explain the board reset operation as an example: Sub-step 1. Each dimension of the managed object is described in a natural language. The description includes:

1) The managed object operation identifier is used to uniquely identify a type of dimension measurement operation: Assume that the unique identifier of the board object reset operation is 1 and the non-query type operation;

2) The unique identifier of the transmitting side of the operation: Assume that the identifier is a number 2001;

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

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

5) The processing method address corresponding to the receiving side: Assume that there is a stored procedure in the database named BoardResetResultReceive (single board reset result processing).

Sub-step 2. The structure of the transmission frame and the structure of the return frame are described using a natural-like language. The descriptions are as follows:

1) The managed object operation identifier is used to uniquely identify a type of dimensional measurement operation;

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

3) Transmitting side transmission frame structure: If the managed object operation identifier is 1, the transmission frame structure is one The numeric type of the byte (for example, the attribute length of the board number is a one-byte numeric type);

4) Receive frame return frame structure: If the managed object operation identifier is 1, the return frame structure is also a one-byte numeric type;

5) The description of the send frame and the return frame is the same, using the same set of rules.

Sub-step 3. The sending-side processing method is described using a natural-like language. The descriptions include:

1) The process of generating a transmission frame by the transmitting side.

In the BoardResetRequestSend processing method address, generate a following sending frame according to the input board ID:

Struct

{

BYTE iProcID; / / store managed object operation ID 1

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

Sub-step 4. The receiving-side processing method is described using a natural-like language. The descriptions include:

1) For the non-query operation, the return content only includes the operation result code, and the receiving side interprets according to the meaning of each operation result code described in advance;

2) For the query class operation, the returned content is the attributes of the managed object, which can be interpreted according to the description of the managed object, and the query result of the managed object is given;

The operation result code of the non-query type operation needs to be defined in advance, for example, 0 means that the reset is successful, and 1 means the reset fails.

The board is reset to a non-query operation. The return content only includes the operation result code, for example:

Struct

{ BYTE by Result;

}

After describing the sending frame processing method and the returning frame processing method corresponding to each of the managed objects in the natural language, the specific process of implementing the board reset operation by the method of the present invention can be given, as shown in FIG. 1 , including The following steps:

Step 101: The user performs an operation of the managed object operation identifier being 1;

Step 102: The dimension testing system performs a query according to the unique identifier in all operations of the system described by the natural language, and obtains a unique identifier of the transmitting side as 2001, and finds a sending side processing method BoardResetRequestSend according to the unique identifier;

Step 103: The Board ResetRequestSend method generates a sending side sending frame, and sends the frame to the host for operation;

Step 104: Receive a response message, where the unique identifier of the message is 1, and it can be known that the operation message of the managed object operation identifier is 1.

Step 105: The system is queried according to the unique identifier in all operations of the system described by the natural language, and the unique identifier of the receiving side is obtained as 3001, and the receiving side processing method BoardResetResultReceive is found according to the unique identifier;

Step 106: The BoardResetResultReceive method performs receiving side processing, and obtains an operation result code of 0. According to the operation result code definition, 0 indicates 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 dimension measurement operations of the managed object, the timer can be registered in the system, and the value of the operation parameter is defined, and the timer is uniformly triggered by the timer. For example, the reset operation of the board is used as an example. As long as the object class number and the object operation number and the operation attribute value are given (for the board reset operation, it is the board number), define the execution time of the operation (may be For a fixed time, it can also be a period, for example, three in the morning, the timer is bound to a certain dimensioning operation (such as resetting the first board). After the timer is triggered, the automatic measurement operation can be completed. That is, the calibration of a board can be reset periodically. For example, resetting a board at 3 am every day.
