The core of the invention is to provide an NTB communication method to relatively ensure the accuracy and reliability of data communication. Another core of the present invention is to provide an NTB communication apparatus, device and storage medium.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a flowchart of an NTB communication method according to an embodiment of the present invention. Referring to fig. 1, the NTB communication method includes the following specific steps:
step S10: and receiving a communication request sent by a request end.
The communication request includes port information of a target NTB port in the request terminal.
It should be noted that the execution main body of the method should be a response end for responding to the communication request of the request end, and in the method, the request end and the response end are both installed with an NTB card, so that both the request end and the response end have corresponding NTB ports. The communication request transmitted to the response end contains the port information of the target NTB port in the request end, so that the response end further judges the data communication qualification of the target NTB port of the request end. In addition, the port information of the target NTB port in the method should uniquely characterize the NTB port identity of the target NTB port, so as to ensure the overall accuracy of NTB communication.
Step S11: it is judged whether the communication request is a transmission request, and if so, step S12 is executed.
Step S12: it is determined whether the port information of the target NTB port has been recorded in advance, and if so, step S13 is executed.
Step S13: data communication is conducted with the target NTB port through the local NTB port.
It should be noted that, when the communication request is a transmission request, that is, when the request end initiates a data interaction request to the response end, the response end determines whether the port information of the target NTB port is locally recorded, so as to define whether the target NTB port of the request end has a communication qualification with the local NTB port, that is, only by recording the port information of the target NTB port of the request end to the response end in advance, the response end can perform data communication with the target NTB port of the request end through the local NTB port, thereby avoiding a situation that any NTB port of the request end can perform data communication with the local NTB port of the response end, and improving overall controllability of data communication of the NTB ports between different devices.
The NTB communication method provided by the invention firstly receives a communication request which is sent by a request end and contains target NTB port information in the request end, judges whether the communication request is a transmission request, further judges whether the port information of the target NTB port is recorded locally in advance if the communication request is the transmission request, and further performs data communication with the target NTB port through the local NTB port if the communication request is the transmission request. In the method, the transmission request transmitted by the request end contains the port information of the target NTB port of the request end, and the port information is further used as the basis for judging whether the request end has the communication qualification, and the data communication is carried out between the local NTB port and the target NTB port only when the port information of the target NTB port is locally recorded in advance, so that the limitation on the data communication of the NTB port between the devices is realized, and the accuracy and the reliability of the data communication are relatively ensured.
Fig. 2 is a flowchart of an NTB communication method according to an embodiment of the present invention. Referring to fig. 2, the NTB communication method includes the following specific steps:
step S20: and receiving a communication request sent by a request end.
Step S21: it is determined whether the communication request is a transmission request, and if so, step S22 is performed, otherwise, step S23 is performed.
Step S22: it is determined whether the port information of the target NTB port has been recorded in advance, and if so, step S24 is executed.
Step S23: it is determined whether the communication request is a registration request, and if so, step S25 is performed.
Step S24: data communication is conducted with the target NTB port through the local NTB port.
Step S25: and recording the port information of the target NTB port.
It should be noted that, the key point of the present embodiment is that when the transmission request of the request end is specifically a registration request, that is, when the request end requests the data communication right of the target NTB port from the response end, the response end records the port information of the target NTB port to the local, so as to ensure that when the request end transmits a transmission request containing the port information of the target NTB port, the request end can normally respond to the transmission request of the request end, and perform data communication with the target NTB port of the request end through the local NTB port, thereby further ensuring accuracy and reliability of data communication. In addition, in this embodiment, the recording of the port information of the target NTB port may specifically be to record the port information of the target NTB port in a data structure or a log preset in the response end, which is not limited specifically herein.

The embodiment saves the storage space of the response end to a certain extent.
In addition, as a preferred embodiment, after recording the port information of the target NTB port, the method further includes:
and sending response information containing the port information of the local NTB port to the request end so as to record the local NTB port to the request end.
In the embodiment, after the response end records the port information of the target NTB port of the request end to the local, the response end sends the response information to the request end, wherein the response information includes the port information of the local NTB port of the response end, so as to inform the request end of successful registration, and after the request end records the local NTB port of the response end, the NTB port used by the response end can be verified in subsequent NTB data communication with the response end, thereby further ensuring the accuracy and reliability of data communication.
In addition, as a preferred implementation, the communication request includes port information of a plurality of target NTB ports in the request end;
correspondingly, the data communication with the target NTB port through the local NTB port comprises the following steps:
and carrying out data communication in a parallel mode through the local NTB port and the target NTB port.
