Abstract

The embodiment of the present invention discloses an event notification method and a system for event notification. The system includes at least one cluster node, multiple network devices, and multiple event subscribers. The event subscribers include clients or servers; the cluster nodes and Multiple network devices are connected, each network device is connected to one or more event subscribers, and one or more event subscribers connected to the same network device subscribe to the same topic. After receiving the event to be notified, the master node of the cluster queries the correspondence between the subject of the event and the address of the network device according to the subject of the event to be notified, and obtains the address of the target network device corresponding to the subject of the event to be notified. The address of the device sends the event to be notified to the target network device; finally, the target network device multicasts the event to be notified to all event subscribers connected to itself. It reduces the amount of message transmission at the network layer and improves the efficiency of event notification.

Description

technical field [0001] The invention relates to the technical field of distributed systems, in particular to an event notification method and a system for event notification. Background technique [0002] A distributed system is a computer system consisting of multiple interconnected processing resources that cooperate to perform the same task under the control of the overall system, relying on centralized programs, data, or hardware. These resources may be geographically adjacent, or , geographically dispersed; users do not feel that these resources are distributed, as if they are a unified whole. [0003] In a distributed system, how to coordinate different services is one of the key issues. As a low-coupling service interaction method, the event notification mechanism has been widely used. The event notification mechanism includes three roles: event publisher, event subscriber and event proxy cluster. Among them, the event publisher is the event producer; the event proxy...
