【Abstract】 Using Dexter model as the standard, absorbing the advantages of Amsterdam and Trillis model, this paper extends the Distributed Multimedia Synchronization Model based on Petri nets to hypermedia synchronization, that is, Distributed Hypermedia Synchronization Model DHSPN. This model can deal with the three main problems (hyperlink, object synchronization and user interactions) relatively well in distributed hypermedia systems.更多还原
