Method of inter master-slave nodal state synchronization

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...

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.

[0018] The disadvantage of this method is that when the corresponding slave node communication changes from "abnormal" --> "normal", it is necessary to report all the latest status values ​​of all attributes of the node, some of which are already synchronized between the master and slave nodes. Therefore, this method leads to a lot of unnecessary message traffic; and the master node also needs to judge which of the status information reported by the slave node has already been processed and does not need to be processed again, so this method also increases the processing of the master node cost
