Communication method, device, electronic equipment and storage medium based on distributed system

Abstract

The embodiment of the invention discloses a communication method, device, electronic equipment and storage medium based on a distributed system. The distributed system includes at least two hosts, and each host has multiple nodes. The method includes: any current node in the distributed system receives topology messages broadcast by other nodes; wherein, the topology message includes at least the service to be sent The message topic of the message and the message topic of the subscribed business message; the current node determines at least one target node from other nodes according to the topology message; wherein, the message topic of the business message to be sent by the target node is the same as that of the business message subscribed by the current node The message topic is the same, and / or the message topic of the business message subscribed by the target node is the same as the message topic of the business message to be sent by the current node; based on the message topic, the current node sends a business message to each target node and / or receives from each target node business news. Communication costs can be reduced and communication risks avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to a communication method, device, electronic device, and storage medium based on a distributed system. Background technique [0002] A distributed system is a system composed of a group of computer nodes that communicate through a network and coordinate their work to complete a common task. [0003] In existing communication methods based on distributed systems, if one end node initiates a connection to another end node, the node that initiates the connection needs to know the IP address and port number of the connected node. Generally, the IP addresses and port numbers of each node are stored in a local configuration file, or in a centralized server. Specifically, if one end node initiates a connection to the other end node, the node initiating the connection can look up the IP address and port number of the connected node in the local configu...

AI Technical Summary

Problems solved by technology

If the IP address and port number of each node are stored in a local configuration file, the maintenance cost of the configuration file is relatively high, and synchronization is difficult; if the IP address and port number of each node are stored in a centralized server, There is a single point of failure in this way, and the risk is greater
