Description

System and method to control / manage each port independently in communication board having several communication ports

The present invention relates to an operating system and method of a communication port using the SDLC protocol. The present invention relates in particular to a system and method for controlling any port independently of the other when using multiple communication ports on one communication board at the same time.

Communication board products are becoming more versatile to provide more than one communication port on one board or to use more than one protocol.

Therefore, even in an environment in which one process controls multiple ports on a board, multiple ports must be independently activated without any interference or influence between the ports and independently disabled (port reset) if necessary.

However, as shown in FIG. 1, since a data structure managed or controlled by a user command in a data link layer of a communication board is related to a board, it is impossible to control and manage each port at a user level.

For example, when resetting port # 0 of three ports simultaneously running as shown in FIG. 1, since there is no data structure for controlling or managing by port, the entire communication board is inevitably reset.

Therefore, there is a problem that port # 1 and port # 2 that were in use are also reset.

Therefore, in order to solve the above problems, the present invention adds a control and management data structure for each port in the data link layer of the communication protocol in an environment in which multiple physical communication ports are provided in one communication board. Accordingly, an object of the present invention is to provide a system and method for independently controlling / managing each port in a communication board having multiple communication ports so that each communication port can be independently controlled or managed.

One embodiment of a system for controlling / managing each port independently in a communication board having multiple communication ports according to the present invention for achieving the above object is a user process (Process), kernel driver (Kernel Driver) In the communication board that exchanges data with the system bus and the system bus,

A data structure related to information and parameters of the board;

Data structures for control / management of the ports; And

It comprises the port processing module.

In the present invention, it is preferable that a control / management data structure for the port is allocated for each port.

In order to achieve the above object, a preferred embodiment of the method for controlling / managing each port independently in a communication board having a plurality of communication ports according to the present invention,

Transmitting a command to a kernel driver by a user;

Transferring a user command from the kernel driver's IOCTL instruction processing routine to a communication board;

Analyzing a user command transmitted from a data link layer (SDLC) of a communication board, changing a content of a control / management data structure for a corresponding port, and processing the command for the corresponding port;

Informing a kernel drive of a result of processing a user command; And

The kernel drive passes the result to the user process.

In the present invention, in the step of the data link layer of the communication board processing a command for the corresponding port, if the user command is active (All), all data of the corresponding port indicated by the control / management data structure of the corresponding communication port It is desirable to activate the port by initializing the structure and registering it in the control / management table,

In the step of processing a command for a corresponding port by the data link layer of the communication board, if a user command is inactive (DeActive), all data structures of the corresponding port indicated by the control / management data structure of the corresponding communication port are initialized. It is recommended to deactivate the registered information of the port in the control / management table.

Referring to the configuration of the present invention with reference to Figure 2, when one communication board provides multiple communication ports to control and manage each communication port independently control block (data structure) to be independently controlled and managed This is necessary.

Therefore, in the data link layer (SDLC) running on the communication board, a control or management data structure for each communication port is provided to open a path for processing control commands for each communication port coming down from the user. Its main processor analyzes user commands and selects a data structure for control or management of that port, enabling all data structures on that port to be activated or deactivated (port resets) independently of other ports. .

To this end, as shown in FIG. 2, a control / management data structure (P1 to P3) for each port and its processing module were added.

Referring to Fig. 2, the operation of the present invention starts with a user command selected according to a user's needs in an environment in which one communication board provides several communication ports.

The situation for these users

-To activate only one communication port among multiple communication ports

-To deactivate only one communication port among several communication ports

-There are times when you want to restart only the corresponding port due to the failure of a specific communication port.

The processing sequence of the operation is as follows.

The user passes the command to the central driver.

→ User commands are passed from the central driver's IOCTL command processing routine to the communication board.

→ The data link layer of the communication board analyzes the transmitted user command, changes the contents of the control / management data structure for the port, and processes the command for the port.

At this time, if the user command is activated, the data link layer initializes all data structures of the corresponding port indicated by the control / management data structure of the corresponding communication port and registers the control / management table to activate the port.

If the user command is inactive, the data link layer initializes all data structures of the corresponding port indicated by the control / management data structure of the corresponding communication port and removes the registration information for that port from the control / management table.

The data link layer informs the central driver of the result of processing a user command, and the central driver passes the result to the user process.

According to the present invention operating as described above, in an environment in which one communication board provides several communication ports, each communication port is independently controlled and managed by a user command, thereby affecting the other communication ports in use at the same time. By disappearing, you can use all the performance of the improved communication board, improving your work efficiency and reducing your costs.
