NTP
Network Time Protocol
NTP is known as Network Time Protocol, and is an Internet
protocol used to synchronize the clocks of computers/domain to specify time. It
applies both on protocol and client-server programs.
The NTP client sends a time-request to the NTP server, then the client measures
the link delay and adjust its local clock to match the clock at the server's
end.
Primary NTP Server: Primary NTP servers are synchronized to a reference clock that is directly traceable to UTC (Coordinated Universal Time).These servers then distribute this time data to NTP secondary servers and NTP clients down stream.
Advantages
- During billing services we are able to know the time accurately to provide the clear-cut charges free from any wrong billing.
- Tracking security breaches and incidents which could affect a large number of devices and applications can be nearly impossible if timestamps in logs are inaccurate. Time is often the critical factor for logging any security event or incident over a network.
- Financial services like transactions need highly accurate time reference.
- It helps the critical travel and transportation system.
- Stock market communications and transactions require careful synchronization of time.
- Email and network communications can be tough if timestamps are incorrect.
