A cluster communication system and method for improving message delivery performance

Abstract

The present invention relates to the technical field of network communication, and in particular to a cluster communication system and method for improving message delivery performance. The system includes a message publishing terminal, a message server cluster including multiple message servers, a message subscribing terminal and a distributed coordination service cluster; the present invention has a global scalable distributed design without single-point clustering; if one or more nodes at the message publishing end or subscribing end fail, other nodes in the same group can continue to send or receive messages without It will interrupt the processing flow of messages; adopt the index-based distributed file storage scheme, which effectively avoids the shortcomings of existing DB and file storage, and makes the reading and writing of messages more efficient; using the long-polling PULL message delivery method, in While ensuring the real-time nature of the message, the throughput is taken into account.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a cluster communication system and a method thereof for improving message delivery performance. Background technique [0002] In modern distributed systems, asynchronous message transmission between multiple nodes in the cluster usually relies on messaging systems. Different from the original point-to-point communication, the message system assumes the responsibility of data routing in the entire application system, and can effectively decouple each subsystem. [0003] A message system that follows the publish-subscribe model generally consists of three objects: a message publisher (Producer), a message server (Broker), and a message subscriber (Cosumer). The message publisher is responsible for generating messages and sending them to the message server. Messages can be divided into different categories according to topics. A message subscriber subscribes to one o...

Problems solved by technology

PULL mode means that the client actively pulls data from the server. This method has high throughput but low real-time performance.

Neither of these two delivery models can meet the application scenarios that have strict requirements on real-time and throughput

[0008] With the continuous expansion of cloud computing and the scale of the Internet, there are more and more business scenarios with high concurrency and massive message flow requirements. If the traditional message system is used, when faced with explosively increased access pressure, the traditional message system may There will be slow message processing, message loss, and even message server downtime.
