Introduction cont.
• The NTP Pool Project, a self-voluntary organization, is founded by Adrian von Bidder.
• The main goal of the NTP Pool Project is to provide the free service of the time synchronization.
• The union of the assistances from the different sources equips the NTP Pool Project to become a successful project.

Conclusion
• The NTP Pool Project is a well-designed network system based on the distributed framework to avoid the network traffic.
• After installation of the NTP software, we need to check the NTP setting to avoid the selection of the NTP server too far away.
