NTP is almost as old as the Internet itself. It is designed and developed by Dr David Mills of the University of Delaware, in continuous operation since 1985 and constantly updated. NTP is a protocol for the Internet, the computer allows the network to synchronize the clock.
In the modern global economy synchronization of time is essential for the implementation of rapid response activities such as booking an airline ticket bid on eBay. If the clocks are not synchronizedHowever, if you find a place in the air after he bought on eBay and administrators are not able to discover, whose bid was the last.
Atomic Clock Instructions
NTP synchronizes network on the Internet or WAN / LAN (LAN / WAN), it is time synchronized to a reliable clock. This source can be like a computer clock atomic clock or a clock at a time or an absolute time.
Network Time Protocol - NTP server to tell, and the network time synchronization
MostNetwork administrators can more completely by an external source, mainly because of human resources for the network simply an atomic clock NTP server or special radio-based time (usually in the national laboratories, physics) or GPS.
The universal time scale called UTC (Coordinated Universal Time) to a global network coordinated at the same time, developed support functions such asSeconds - added to compensate for slowing the rotation of the Earth
The NTP algorithm (a complex sequence of instructions) to keep time in sync with the ongoing investigation into the origin and moves in accordance with time on his own clock to the network and each device has to change, if that.
NTP timestamp for the time of the day, some deputies. Linearly with time and date each time is always greater than the previous one. NTP timestampin two formats, but the second relay January 1, 1900) in some period of time (known then as a general contractor, 00:00 to NTP algorithm the amount of the stamp of time, forward or backward, the system or network Destination hours.
Analysis of the NTP timestamp value, including the frequency of errors and stability. The NTP is always considered that the quality of both the reference clock and themselves.
The Program (NTP services daemon on UNIXWindows is running in the background). NTP receives information from both packets (a block of data), but is not prepared to say that setting the time, more storage, more tests and a series of protocol specifications have to believe. Only if the answer to the server to respond to these tests are not the NTP information. This is usually about five minutes (five good samples) until a NTP server as the source of the synchronization is successful.
Microsoft, the installed version of NTPoperating systems Windows 2000, it is recommended that physical resources, such as the time reference is used as Internet sources can not be verified.
Authentication ensures that everyone has the date and time is the time reference by analyzing a set of keys that are sent with the weather data provided. NTP, encryption, Message Digest (MD5) confirmed the key is not encrypted, analysis, and the source of the time, know-Controla reliable set of keys.
The best solution is to use the NTP server technicians and certified reference materials when the transmission network and GPS to the radio (also known as Doctors Without Borders in the UK or the U.S. WWVB known).
NTP judges the distance to each network device from the source of the time and place them in layers. to end this level of movement of groundwater and to ensure their accuracy. 0 reference clocks are stratum instruments such as the direct linkWorkplace. 1. Layer 0-level device connected computer, while the layer 2 on a computer.
NTP NTP.org download supported and updated. The latest version v 4 is a simplified version of NTP (SNTP), fewer features and tools and applications (and is also available in earlier versions of Windows) is used when the time precision is not important.
