The 4th NICT Conference on Research Activities(Nov 30, 2005)
Tsukasa Iwama(Senior Researcher) presented the following results of our
research on The 4th NICT Conference on Research Activities.
The 4th NICT
Conference on Research Activities(Nov 30, 2005), at My Dome Osaka in
Japan
"Research and Development of the Trusted Time Stamping
Techniques"
Development of A Hardware SNTP Server(Apr 22, 2005)
■Summary
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
Demonstration servers can be accessed with the following IP
addresses;
sntp1.nict.go.jp IPv4:133.243.237.141
IPv6:2001:e38:2020::123
sntp2.nict.go.jp IPv4:133.243.237.142
IPv6:2001:e38:2020::124
※These servers use Japan Standard Time as their
clock source.

■Note
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.
