Internet-based method for building event-driven mechanism programming model

Abstract

The invention discloses an Internet-based method for building an event-driven mechanism programming model and belongs to the field of Internet application and development. The method comprises: firstly, enabling computing nodes to receive and transmit a request; secondly, establishing a direct and equipotent interactive protocol among the computing nodes and establishing message-based event listening mechanisms at the computing nodes; thirdly, establishing a dynamic cluster among nodes having common needs and transmitting data by using a data multicast mechanism in the dynamic cluster; fourthly, monitoring nodes in the dynamic cluster, and transmitting data of an event occurrence node to other nodes through the data multicast mechanism; and finally, establishing an event-driven programmingmodel according to the type of data transmitted. On the premise of avoiding network cost increase, the method increases network computing resources; and meanwhile, a event-driven mechanism in the programming model allows a network user to acquire concerned event information timely and automatically. Therefore, network service is effective, convenient and humanized.

Description

technical field [0001] The invention relates to a method for establishing a programming model based on an Internet event-driven mechanism, and belongs to the field of Internet application development. The main technologies included are distributed computing, Internet communication, remote event-driven model, multicast technology, and remote message mechanism. Background technique [0002] Event-driven mechanism has been widely used in ordinary programs and distributed programming. As a programming model, event-driven provides a registration method to assist the system to monitor potential events; and immediately use the notification mechanism to make the system that cares about the event respond to the event in a timely manner after the event occurs. Without the support of this mechanism, the programming workload of developers will be greatly increased, and the system efficiency will also decrease. However, such an event-driven mechanism does not exist in the current Inter...

AI Technical Summary

Problems solved by technology

In Internet applications based on static resources, there are no more events to track except for limited events such as data release, update, and deletion

[0007] Third, early and current Internet servers have limited computing resources

[0008] Fourth, there is no constant network connection in the early and current Internet

However, HTTP, a common communication protocol on the Internet, requires each connection to have a limited life cycle, so as to ensure that the limited connection resources of the server can be used to cope with the access requests of potential clients.

In the absence of a persistent network connection, the implementation of the remote event mechanism is limited on network resources

Even if a potential event occurs, limited network resources prevent the event notification mechanism from running in a timely manner

[0009] Fifth, no proper multicast mechanism existed in the early and current Internet

[0010] Sixth, the pure thin client mode prevents the client from participating in Internet computing

However, since the client cannot participate in Internet computing, and neither the client nor the server nor the client can generate collaborative computing, the event-driven mechanism cannot be established in the early and current Internet.
