Abstract

We propose a time synchronization model on the Internet using kalman filtering to provide the stability to time synchronization. To verify the new stable time synchronization model, we introduce the characteristics of the Internet transmission delays and present the comparison results with SNTP(Simple Network Time Protocol) time offset model. SNTP has been widely used as a time synchronization method on the Internet. While SNTP provides a very simple usage, SNTP may not provide the stable services, since SNTP does not consider the several essential error factors of the Internet. In order to overcome the instability of SNTP, we analyze the process of time estimation of SNTP and the premise. To verify and apply the proposed model, we present the measurement results and analysis.
