SNTP server and client system for home use

This paper proposes a compact time sharing system for home use applying the Simple Network Time Protocol. The compact SNTP server/client system for home appliances has been developed as an extension of an SNTP client application the authors previously proposed. The newly developed system can obtain the time from time detection sensors directly without upper layer NTP servers. For verification, the developed system operated on a real-time operating system, T-Kernel/Standard Extension, with a 32-bit RISC MPU, SH7727.
