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"
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 version： SNTP ver.4
Speed： GbE wire-speed
Timestamp accuracy： 8 nanoseconds
Demonstration servers can be accessed with the following IP
sntp1.nict.go.jp IPv4:188.8.131.52 IPv6:2001:e38:2020::123
sntp2.nict.go.jp IPv4:184.108.40.206 IPv6:2001:e38:2020::124
※These servers use Japan Standard Time as their clock source.
