METHOD FOR CONTENT CHANGE NOTIFICATION IN A CLOUD STORAGE SYSTEM, A CORRESPONDING CLOUD BROKER AND CLOUD AGENT

摘要

A method for notification of content changes across different applications that share same content in a cloud storage system comprises: registering at a cloud IO broker applications that require content change notification; informing a cloud IO agent about content for which applications registered with the cloud IO broker for content change notification; monitoring content changes in the cloud storage system and upon each change of a content item: sending a first content change notification from the cloud IO agent to each cloud IO broker that requested content change notification for that content item; identifying at the cloud IO broker applications registered for content change notification for that content item; and multicasting a second content change notification from the cloud IO broker to all applications registered for content change notification for that content item.
