A cause and effect concurrent detection method for large-scale cooperative environment

Abstract

The utility model belongs to the technical field of real-time collaborative group editing, in particular to a consequence concurrent checking method under the environment of extensive collaboration, which is characterized in comprising: a logic time stamp is defined and the logic time stamp belongs to the technical field of real-time collaborative group editing as the direct consequence ordering vector time stamp; the utility model discloses the method to solve the consequence concurrent checking problem during editing the real-time group based on the time stamp. The method comprises the following three steps: estimate whether a remote operation is consequently ready; find the historical operations concurrent with the current remote operation; and estimate the consequence concurrent relationship between two random historical operations. The utility model can be used for editing the real-time group with an arbitrary scale; the performance has no relation to the activity of the collaborative participator, the collaborative environment scale and the total number of the collaborative participators; so the utility model is particularly suitable for being used for editing the real-time group under the extensive collaborative environment with low concurrent level.

Description

technical field [0001] The invention belongs to the technical field of collaborative real-time group editing, and in particular relates to a method for detecting causal concurrency in real-time group editing activities in a large-scale environment. Background technique [0002] Single-user document editing system, including common text editors (such as Vi, Notepad), word processing tools (such as Microsoft Word, WordPerfect), graphics editors (such as Photoshop, MsPaint) and website design tools (such as Dreamweaver, Frontpage) , engineering drawing design tools (such as AutoCAD), etc., have been widely used in people's daily life. [0003] In recent years, with the rapid development of the Internet (Internet) and the trend of economic globalization, these single-user editing systems have been transplanted into a multi-user environment, allowing multiple users to simultaneously browse and edit a shared data object through a computer network, enabling it to It plays an impor...

[0014] 5. Unreliable collaborative environment: The unreliable we are talking about here includes the unreliability of the network environment and the unreliability of collaborative users

In addition, the above-mentioned methods, like the Sun-Cai method mentioned above, also have the possibility of accidentally hiding the conflict of the user's operation intention
