A message delivery method and system based on message queue

Abstract

The invention discloses a message delivery method and system based on a message queue. The method includes: Step 1, the message agent of the source server receives the message data packet sent by the source application program; Step 2, after receiving the message data packet, judging Whether the number of messages in the message queue has reached the predetermined upper limit; Step 3, if the number of messages in the message queue does not reach the upper limit, then the message agent stores the received message data packet in the message queue, and Determine whether the target server for message delivery is connected to the source server, if connected, directly deliver the message data packet to the target application program of the target server, if not connected or the number of messages stored in the message queue has reached the upper limit, then enter the step 4. Step 4: Search for other servers with the same message delivery function to establish a connection with it, and send the message data packet to an intermediate server according to the preset selection rules, and the intermediate server forwards the message data packet.

Description

technical field [0001] The invention relates to a message delivery method and system, in particular to a message queue-based message delivery method and system. Background technique [0002] Messages are mainly used for information exchange between network devices (especially servers). Asynchronous message transmission is widely used in communication systems because it can reduce the system coupling between the message sending end and the message receiving end, and the message sending end and the message receiving end do not need to be online at the same time. [0003] Message passing is an asynchronous communication method, specifically, the direct and reliable message passing between multiple applications running on the same or different machines. Applications communicate with other applications by sending packets of data called messages. [0004] figure 1 It is a schematic diagram of message passing between two application programs in the prior art. like figure 1 As ...

[0006] However, the number of messages stored by each message agent has a certain limit. When the messages stored by the message agent reach its upper limit, a large number of messages are waiting to be processed, which will easily cause slow processing of the agent service and increase the processing pressure of the hardware server. Risk of server downtime and message loss
