Development of A Hardware SNTP Server(Apr 22, 2005)


We have developed a high-precision and high-throughput hardware SNTP server using FPGA(field Programmable Gate Array).
We also started to provide time information with Internet reachablity to evaluate it.

SNTP server

SNTP version:  SNTP ver.4
Speed:  GbE wire-speed
Timestamp accuracy:  8 nanoseconds


Demonstration servers can be accessed with the following IP addresses;

sntp1.nict.go.jp IPv4: IPv6:2001:e38:2020::123
sntp2.nict.go.jp IPv4: IPv6:2001:e38:2020::124

※These servers use Japan Standard Time as their clock source.

This experiment aims to test the performance and function of the newly developed server.
The servers may be interrupted, make incorrect responses, or stop your access to the service at any time without notice.
