Problems solved by technology

[0015] 1. Low communication efficiency: After the slave node reports a message, it must wait for the response message returned by the master node before reporting the next message. There is a time delay in this implementation method, which leads to a decrease in communication efficiency;
[0016] 2. The slave node needs a larger cache: when there are many messages from the slave node, it will inevitably lead to the need for a larger cache to save these messages that have been generated on the slave node but have not been sent, or have been sent but have not received a response.

Example Embodiment

[0061] The main content of the present invention is to provide a method for state synchronization between master and slave nodes, so as to realize state synchronization between master and slave nodes.

[0062] The core of the method of the present invention is:

[0063] 1: In the slave node, determine the unsynchronized status information between it and the master node.

[0064] Each time a state change occurs from the slave node, the state change message is reported to the master node, and then the state information that is not synchronized with the master node is determined according to the response message of the state change message returned by the master node.

[0065] 2: The master node obtains the unsynchronized status information from the slave node, and updates the status information of the master node according to the status information.

[0066] The slave node reports to the master node the determined status information that is not synchronized with the master node, and...

Abstract

This invention provides a kind of method for major-slave nodes status synchronization. It concludes: the asynchronous status information between slave nodes and master nodes is ensured; the master nodes take the said asynchronous status information from slave nodes. According to the said status information, the status information of master nodes is renewed. This invention is adequate for all the communication occasions based on status. It can also increase the system performance greatly.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for state synchronization between master and slave nodes. Background technique [0002] In the field of communication, communication of various information is required between master and slave nodes. There is a special case of communication information between master and slave nodes called status communication. The main characteristics of this type of communication are: the master node is not very concerned about the occasional loss of intermediate state information of the slave node during the communication process, the master node is concerned about the current latest state information of the slave node, that is, the state information between the current master and slave nodes Whether to synchronize. In the communication field, synchronization is a key factor to ensure communication quality, and master-slave synchronization is a widely used synchronization met...
