Research and Algorithm of End-to-End Time Synchronization for Real-time Systems over Internet

An ETSA(End-to-end Time Synchronization Algorithm) is presented for end-to-end real-time control systems over Internet.Using a new time synchronization principle,the proposed ETSA achieves high clock synchronized accuracy through TCP/IP protocol,and it can be implemented simply and easily.Theoretical analysis and experiments through Internet validate the usefulness and effectiveness of the presented algorithm.
