Abstract
Patent of the present invention is related to a kind of new multisegment computer time synchronization realizing method, this method in multisegment by respectively selecting a time synchronized master computer, a Time Synchronization Network is set up between the multisegment multiple stage computers chosen, and set the super master computer that wherein one is multiple stage computers synchronizing network, to realize the time synchronized of multiple stage computers, and then all computers in selected time synchronized host computer synchronization to the affiliated network segment in each network segment, to realize the time synchronized of all computers of multisegment.This method uses intercomputer lock in time, the problem of effectively solving time synchronized in a network segment or multiple network segments.
Description
Technical field
Patent of the present invention is related to computer network communication field.
Background technology
In the world of computer, the time is important in the extreme, such as this scientific research activity of rocket launching, to the time
Uniformity and accuracy requirement are just high in the extreme, are the time according to this computer of A, also according to B this computer when
Between, NTP is for solving this problem, NTP（Network Time Protocol, NTP）It is for making
A kind of agreement of each computer time synchronization in network.Its purposes is that computer is time-synchronized to UTC Universal Time Coordinated
UTC, its precision is up to 0.1ms in LAN, and its local precision most of on the internet can reach 1-50ms.
NTP will provide correct time, must just there is correct time source, and that can use the GMT, answer
Case is negative.Because the GMT is the time measurement system based on earth rotation, but the earth it is daily from
It is that some are irregular to turn, and slow acceleration, and therefore, the GMT is no longer made as the standard time
With.The new standard time, is the universal time UTC given the correct time by atomic clock（Universal Time Coordinated, generation
Boundary's universal time coordinated）.So the time source that NTP obtains UTC can be atomic clock, observatory, satellite, can also be from Internet
Obtain.
But in many application environments, computer system need not accurately time, it is more also without internet environment
Be the collaboration applications in one or more network segments, only desire to can have a kind of method can be by the meter in one or more network segments
Calculation machine time synchronized is consistent time point, and time during ensureing that multiple stage computers cooperative system is applied is consistent.
Patent of invention content
Patent of the present invention is related to a kind of new multisegment computer time synchronization realizing method, and this method in multisegment by respectively selecting
A time synchronized master computer is selected, a Time Synchronization Network is set up between the multisegment multiple stage computers chosen, and set
Wherein one be multiple stage computers synchronizing network super master computer, to realize the time synchronized of multiple stage computers, and each network segment
In then all computers in selected time synchronized host computer synchronization to the affiliated network segment, to realize all calculating of multisegment
The time synchronized of machine.This method uses intercomputer lock in time, effectively solves the time in a network segment or multiple network segments same
The problem of step.
