摘要内容:

Real-time collaborative editing group of users to view and edit the same time from geographically dispersed sites connected by communication networks.Consistency maintenance in concurrent access of the key issues in designing these types of systems.This paper proposes a P2P-based locking schema for concurrency control in internet-based real-time collaborative editing systems.This schema can distribute locking services to all collaborative sites and quickly find out the locking service nodes of given shared objects. The characteristic of distributed locking services solves the hot spot problem in centralized locking schema, and the capability of locating locking service nodes resolves the broadcast communication problem in thelocking schemas. It also provid the basic locking function in collaborative editing systems and can be used in varied locking polices.
