Detailed Description

Features and exemplary embodiments of various aspects of the present invention will be described in detail below, and in order to make objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

There are many types of communication devices, such as a programmable telephone exchange, a router, an exchange, a wireless base station, etc.

Communication equipment typically includes one or more subracks, each subrack having one or more board card modules. The management software module for a communication device is often referred to as a device management subsystem, which is an important subsystem of the overall communication device software.

The device management subsystem can establish a software mapping of the hardware resources and provide the software mapping to interface to other software modules. The other software module can utilize the interface to acquire the resource information of the communication equipment and utilize the resource information to complete the interoperation function with the hardware.

The software mapping module can complete software mapping of the connection relation between the board cards. The connection relationship of the board cards on the board cards of the communication equipment can be various. Many times, the integrated circuit boards are not changed, and only after different connection modes between the integrated circuit boards are changed, the integrated circuit boards can become different integrated circuit boards. This mapping may be used by hardware drivers and other software modules to accomplish the various communication functions.

For example, when a system needs to configure an interconnection interface of a board, another board needs to be interconnected from the software mapping module, and corresponding configuration is completed, so as to ensure normal communication between the boards.

For the board hardware, another important task of software mapping is to map all external connection interfaces, including interfaces inside the system and interfaces outside the system, and to map the user name and user index of the interface with the hardware index.

In the related art, software mapping modules of hardware resources in an equipment management subsystem on communication equipment are all distributed in different board drive modules, and the software mapping of the hardware resources is realized only for one hardware board or a series of hardware boards with small hardware difference. Therefore, the connection relation between the boards is basically not realized clearly and independently, and is basically solidified in the codes of the board hardware. There is a code correspondence for each connection. The mapping of the hardware external connection interface to the board card is generally distributed in the hardware driver related to the interface. The connection relationships among the board cards are all solidified in the operation program of the board cards, so that the expandability and maintainability of the board cards are poor, and meanwhile, the transportability and the adaptability of the board cards are poor.

Therefore, embodiments of the present invention provide a method, an apparatus, a device, and a storage medium for determining a connection relationship, which can improve expandability and maintainability of a configuration board in a communication device.

For convenience of understanding the embodiment of the present invention, a method for determining a connection relationship provided in the embodiment of the present invention is first described in detail.

When the second board card is the first board card, the first board slot interface may be a pre-configured interface, and is not configured on the first board card. Under the condition that the first board slot interface is not connected with other board slots and the second board slot interface is not connected with other board slots, the first board slot interface is determined to be the board slot interface of the first board card, and the connection relation between the first board slot interface on the first board card and other board cards is established.

In some embodiments, there are a plurality of board slot interfaces of the first board card, and each of the board slot interfaces can establish a connection relationship. The connection relationship between the first board slot interface and the second board slot interface is established, and the third board slot interface of the first board card can be obtained again to establish the connection relationship between the third board slot interface and the second board slot interface.

And when the connection information of the third board slot interface does not comprise the connection relation between the third board slot interface and the third board card, establishing the connection relation between the third board slot interface and the second board slot interface.

In some embodiments, different cards are interconnected by a card-slot interface. The card slot interface is generally composed of a plurality of connectors. The same board card slot interface is physically represented as a container port and a receiving port. The ingress may generally lack several connectors. Each connector will contain several hardware board external interfaces.
