Abstract

In a distributed network, the clock synchronization accuracy is an important factor that affects the real-time performance of the network. In order to meet the requirements of high-precision of network clock synchronization, this paper conducts the research to the Precision Time Protocols (PTP), and elaborates the principle of the high-precision synchronization. A simulation was done for distributed video surveillance star network.The simulation results verified the correctness of the algorithm, at the same time, combined with the PTP, the simulation results were analyzed, a conclusion that path symmetry is a statistical concept was gotten and the star network time synchronization offset range was also obtained.
