Conflict Control Locking in Distributed Cooperative Graphics Editors
نویسندگان
چکیده
The communication latency presents a major challenge to achieving high responsiveness for Internet-based cooperative editing systems. In this paper, we propose conflict control locking (post-locking) schemes for conflict resolution in real-time object-based cooperative graphics editors. With these schemes, no locking request is needed before applying an editing operation to an object, instead, a lock will automatically be generated by the system i f a conflict occurs. Lock ownership assigning rules ure devised for the schemes. With a spec$c post-locking approach, algorithms and implementation techniques, such as, lock synchronisation detection, voting, and group intention realisation, are discussed in detail.

Optional Instant Locking in Distributed Collaborative Graphics Editing Systems
Real-time collaborative editing systems are distributed groupware systems that allow multiple users to edit the same document at the same t ime from multiple sites. A specific type of collaborative editing system is the object-based collaborative graphics editing system. f i a ditionally, locking has been used as the major concurrency control techniques in this type of system.

متن کاملA Multi-version Approach to Conflict Resolution in Distributed Groupware Systems
Groupware systems are a special class of distributed computing systems which support human-computer-human interaction. Real-time collaborative graphics editors allow a group of users to view and edit the same graphics document at the same time from geographically dispersed sites connected by communication networks. Resolving conflict access to shared objects is one of the core issues in the des...
متن کاملAn Integrated Post-Locking, Multi-Versioning, and Transformation Scheme for Consistency Maintenance in Real-Time Group Editors
Intention preservation is an important aspect of consistency maintenance in distributed group editors. In this paper, we first introduce a classification framework for various kinds of intentions, then propose an integrated post-locking, multiversioning, and transformation scheme (LOVOT) for intention preservation. With this scheme, individual users’ compatible intentions are preserved by opera...
متن کاملOptional and Responsive Fine-Grain Locking in Internet-Based Collaborative Systems
Locking is a standard technique in distributed computing and database systems used to ensure data integrity by prohibiting concurrent conflicting updates on shared data objects. Internet-based collaborative systems are a special class of distributed applications which support human-to-human interaction and collaboration over the Internet. In this paper, a novel optional and responsive fine-grai...

Computer-supported cooperative work environments change some of the underlying beliefs about solutions that have been built for distributed computing. Electronic mail and file transfers have worked efficiently and effectively by breaking the information to be transferred into packets and reassembling the packets at the destination. This is not a viable solution for handling shared real time dra...
