Problems solved by technology

However, the disadvantage of this technology is that when the user sets the quality of service target and obtains a reasonable distributed workflow configuration through automatic configuration, he cannot immediately make a timely adjustment to the distributed workflow system, and cannot make the system Dynamically adjust to meet the required configuration requirements

Embodiment Construction

[0027] Such as figure 1 As shown, the present invention includes three core components, namely: a workflow service deployment controller, a workflow service container and a workflow service unit. These components are all running under the Jini network, and the components communicate and complete the entire automatic configuration process mainly through the multicast notification protocol, multicast registration protocol, unicast registration protocol and workflow service dynamic deployment protocol.

[0028] The workflow service deployment controller: it is the control end of the system, it uses the multicast notification protocol to declare its own existence, and uses the workflow service dynamic deployment protocol to complete the service deployment and control of the entire system; among them, in order to realize the workflow service The dynamic deployment of units requires a workflow service dynamic deployment configuration file to describe the workflow service unit inform...

Abstract

The system including workflow service deployment controller, workflow service container and workflow service unit are operated under Jini network. Communications are realized and automatic configuration procedure is completed through protocols of multicast announcement, multicast log in, and unicast log in, workflow service dynamic deployment. Workflow service dynamic deployment controller or workflow service container finds opposite party, and workflow service container logs in controller through multicast announcement protocol, multicast log in protocol, and unicast log in protocol. Through workflow service dynamic deployment protocol, the controller communicates to the workflow service container so as to realize controlling workflow service dynamic deployment and service life. Taking full advantage of mechanisms such as dynamic addon, dynamic lookup and dynamic finding, the system realizes service life control and dynamic deployment of service unit in distributed workflow system.

Description

technical field [0001] The invention relates to a system in the field of computer technology, in particular to a workflow service automatic configuration system based on Jini technology. Background technique [0002] Jini is a Java-based distributed computing technology, which can be used to easily build a scalable and stable distributed computing environment. Workflow service is composed of many workflow service units; workflow service unit refers to the Jini service that uses Jini technology to realize the workflow engine interface, workflow monitoring interface, and workflow statistics interface in the workflow system. At present, the distribution of workflow management system can be divided into three levels: 1. The distribution of workflow system structure. The so-called distribution of workflow management system architecture means that the workflow management system is regarded as a group of mutual 2. Distributed execution of the workflow machine, the workflow machine...
