Fault-Tolerant Real-Time Collaborative Editing Systems (1999-2000)
If a real-time collaborative editor is to be effectively used over the Internet, the system should tolerant the client and link failures, for the quality of the Internet are unpredictable. In this research we have developed a novel and efficient approach to supporting crash recovery in real-time collaborative editing systems. read more
Real-time and Fault-tolerant Distributed Systems (1996-1999)
If a real-time collaborative editor is to be effectively used over the Internet, the system should tolerant the client and link failures, for the quality of the Internet are unpredictable. In this research we have developed a novel and efficient approach to supporting crash recovery in real-time collaborative editing systems. read more
