Embodiment Construction
[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0026] figure 1 A flow chart showing a synchronous communication method according to a first embodiment of the present invention, the method includes the following steps:
[0027] Step S101, setting multiple synchronization channels between the source device and the target device;
[0028] Step S102, the source device selects the first synchronization channel from multiple synchronization channels, and uses the first one as the current synchronization channel to send the message Msg(Message) to be synchronized to the target device;
[0029] Step S103, when it is detected that the first synchronization channel is abnormal, the source device selects the second synchronization channel from unused synchronization channels, and uses the second synchronization channel to send a message to be synchronized to the target device;
[0030] St...

The invention provides a synchronous communication method for a distributed system, which comprises the following steps: setting a plurality of synchronous channels between source equipment and target equipment; selecting a first synchronous channel from the synchronous channels and using the first synchronous channel to send an awaiting synchronous message to the target equipment by the source equipment; if the first synchronous channel is detected to be abnormal, selecting a second synchronous channel from unused synchronous channels and using the second synchronous channel to send the awaiting synchronous message to the target equipment by the source equipment; and receiving the awaiting synchronous message by the target equipment. The invention also provides a synchronous communication device for the distributed system, which comprises a setting module, a sending module, a switching module and a receiving module. The invention improves the fault-tolerant rate and the reliability of synchronous communication and solves the problem that the success rate of the synchronous communication of a synchronous communication method is lower when an abnormal condition happens in related technologies so as to cause lower fault-tolerant rate and reliability.
Description
technical field [0001] The present invention relates to the communication field, in particular, to a method and device for synchronous communication in a distributed system. Background technique [0002] In a distributed system, in order to enhance reliability, synchronous communication between multiple CPUs (Central Processing Units, central processing units) usually adopts the method of receiving responses, that is, after the target device receives the message sent by the source device, it will return a The ACK (Acknowledge, confirmation) message tells the source device that it has received the message, and the source device will send the message regularly and repeatedly before receiving the ACK message. [0003] The related technology provides a synchronous communication method for distributed systems. In this method, when the sending process of the message or the sending channel is abnormal, and the source device has not received the ACK message from the target device, t...
