System and method for processing resource notification based on aggregation

Abstract

The invention discloses a processing system of a resource noticing and processing mechanism based on the coalition theory, which comprises: a notification process module, a resource management module, a client component and a resource callback interface; and the processing method comprises the following steps: A. when a resource is instantiated by the resource management module, every resource is encapsulated as a subject and appended into a subject container, simultaneously the registration is carried out to a notification agency; B. after a subscription requirement of the subscriber is received by the notification agency, subscription information is appended into the subscription queue corresponding to the subscription subject; C. after the resource management module modifies the state of the resource, the callback interface is triggered for encapsulating an event and later delivers the event to the notification agency, then the notification agency transmits the content of the event to all subscribers subscribing the subject; D. when the resource management module destroys the resource, the subject corresponding to the resource is deleted from the subject container and the registration is cancelled from the notification agency; and E. the steps of A-D are repeated, thus achieving the noticing and processing of the different resources. The invention completely realizes the WS-BrokeredNotification protocol and forms the fully independent notification agency.

Description

technical field [0001] The invention relates to a processing system and processing method of an extensible theme-based Web service notification mechanism conforming to the WS-Notification protocol. Background technique [0002] In the distributed computing system, the computing system is increasingly complex and large, and it is increasingly showing its characteristics of loose coupling, dynamics, and openness, all of which make the development, management and maintenance of the distributed system more complicated. Therefore, as developers and users, people need to use related communication technologies to reduce the complexity of the system. [0003] Asynchronous message interaction mode is very common in today's computer systems. Email, fax, voicemail, etc., are all forms of asynchronous message exchange based on the push model. The asynchronous message exchange mode enables users to get rid of the traditional message exchange mode of instant response, allowing the serve...

Problems solved by technology

[0018] It can be seen that all mainstream research institutions, including the Globus Alliance, have imperfect implementations of the Web service notification protocol, and have not provided a complete implementation of WS-BrokeredNotification
