Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a communication method according to an embodiment of the present disclosure.
The communication method provided by the embodiment of the application is applied to a first storage controller, and can include the following steps:
step S101: and acquiring a real-time communication link between the storage controller and the second storage controller.
In practical applications, the first storage controller may first acquire a real-time communication link between itself and the second storage controller, where the second storage controller is also a controller that communicates with the first storage controller, and since the acquired real-time communication link is a currently available communication link, the second storage controller is capable of acquiring a currently available communication link. In a specific application scenario, the real-time communication link and the like can be counted by the bottom-layer driver of the first storage controller.
Step S102: judging whether the transmission performance of the real-time communication link meets a preset transmission requirement or not; if the transmission performance of the real-time communication link meets the preset transmission requirement, executing step S103; if the transmission performance of the real-time communication link does not reach the preset transmission requirement, step S104 is executed.
Step S103: and according to the principle of selecting a communication link with high transmission performance, selecting a target communication link meeting the preset transmission requirement from the real-time communication links, and communicating with the second storage controller based on the target communication link.
Step S104: and sending prompt information for representing the establishment of the communication link.
In practical application, in the prior art, when the number of real-time communication links is large, the first storage controller may randomly select a target communication link from the real-time communication links, so that the transmission performance of the selected target communication link is poor, and the target communication link needs to be continuously selected again, thereby increasing the routing consumption, so that in order to reduce the routing consumption, the first storage controller can judge whether the transmission performance of the real-time communication link meets the preset transmission requirement after acquiring the real-time communication link between the first storage controller and the second storage controller; if the transmission performance of the real-time communication link meets the preset transmission requirement, a target communication link meeting the preset transmission requirement can be selected from the real-time communication links according to the principle that the communication link with high transmission performance is selected firstly, so that the transmission performance of the selected target communication link can meet the preset transmission requirement only by one-time selection, and then the target communication link is communicated with a second storage controller; if the transmission performance of the real-time communication link does not reach the preset transmission requirement, at this time, if the communication is performed according to the existing real-time communication link, the preset transmission requirement is difficult to meet, the communication efficiency between the storage devices is affected, and the preset transmission requirement cannot be met no matter how the first storage device performs the routing, so that prompt information for representing the establishment of the communication link can be sent at this time to prompt a user to establish a new communication link.
It should be noted that the preset transmission requirement may be a transmission requirement that needs to be met in the information transmission process of this time, or may also be a transmission requirement that needs to be met in each information transmission process, and the like, and the present application is not specifically limited herein. In addition, the number of target communication links meeting the preset transmission requirement may be determined according to actual needs, for example, the number of target communication links may be as small as possible.
The communication method is applied to a first storage controller, and a real-time communication link between the first storage controller and a second storage controller is obtained; judging whether the transmission performance of the real-time communication link meets a preset transmission requirement or not; and if the transmission performance of the real-time communication link meets the preset transmission requirement, selecting a target communication link meeting the preset transmission requirement from the real-time communication link according to the principle of firstly selecting a communication link with high transmission performance, and communicating with the second storage controller based on the target communication link. In the application, the first storage controller acquires the real-time communication link, and after the transmission performance of the real-time communication link is judged to meet the preset transmission requirement, the target communication link meeting the preset transmission requirement is selected from the real-time communication link according to the principle that the communication link with high transmission performance is selected firstly, and finally, the communication is carried out with the second storage controller based on the target communication link, so that the transmission performance can be ensured only by selecting once, and the selection consumption of the storage controllers can be reduced.
The communication method provided by the embodiment of the application is applied to a first storage controller, and in order to accelerate the efficiency of judging whether the transmission performance of a real-time communication link meets the preset transmission requirement, the process can be judged by means of a score, namely, the process of judging whether the transmission performance of the real-time communication link meets the preset transmission requirement can be specifically as follows: determining a real-time performance score of the real-time communication link based on the corresponding relation between the preset transmission performance and the performance score and the transmission performance of the real-time communication link; acquiring a preset performance score corresponding to a preset transmission requirement; judging whether the real-time performance score is smaller than a preset performance score or not; if the real-time performance score is larger than or equal to the preset performance score, judging that the transmission performance of the real-time communication link meets the preset transmission requirement; and if the real-time performance score is smaller than the preset performance score, judging that the transmission performance of the real-time communication link does not meet the preset transmission requirement.
For convenience of understanding, taking the real-time communication link as an example that the real-time communication link includes a first communication link, a second communication link and a third communication link, and the performance score of the first communication link is 30, the performance score of the second communication link is 8, the performance score of the third communication link is 6, and the preset performance score is 16, the real-time performance score of the real-time communication link is greater than the preset performance score, and the transmission performance of the real-time communication link meets the preset transmission requirement; if the real-time communication link only includes the second communication link and the third communication link, the transmission performance of the real-time communication link cannot meet the preset transmission requirement.

That is, in practical application, when the number of a certain type of communication link is large and the number of activated communication links is limited, a target communication link needs to be selected according to the principle that the number of each selected type of communication link is not greater than the maximum activated number of the type of communication link, assuming that the maximum activated number of the certain type of communication link is 3 and 4 such communication links are needed to meet the preset transmission requirement, at this time, only 3 such communication links can be used as the target communication link, and 4 such communication links cannot be used as the target communication link.
The communication method provided by the embodiment of the application is applied to a first storage controller, and in the process of selecting a target communication link meeting a preset transmission requirement from a real-time communication link according to a principle of selecting a communication link with high transmission performance first, the target communication link meeting the preset transmission requirement can be selected from the real-time communication link according to a principle of selecting a communication link with high transmission performance first and a polling principle.
That is, in practical application, when the number of a certain type of communication links is large, in order to ensure the coverage balance of the communication links, a target communication link may be selected according to a polling principle, and if there are 3 certain types of communication links, a second communication link of the certain type is selected when the target communication link is selected last time, and then a third communication link of the certain type may be selected when the target communication link is selected this time.
The communication method provided by the embodiment of the application is applied to a first storage controller, and because a communication link is influenced by external factors, such as weather, line hardening and the like, a communication link fault condition may occur, and at this time, if a faulty target communication link is still used for communication, a preset transmission requirement cannot be met, so that after the target communication link is communicated with a second storage controller, whether the target communication link is faulty or not can be judged; and if the target communication link fails, deleting the target communication link from the real-time communication link, and returning to the step of judging whether the transmission performance of the real-time communication link meets the preset transmission requirement.
