Fig. 3 is the system block diagram according to the present invention for realizing distributed frame sync server group.As shown in figure 3, of the invention
A kind of system for realizing distributed frame sync server group, including,
Multiple frame synchronization servers 2, for the UDP information for carrying current time stamp to be sent to frame synchronization time service server 1 respectively,
The return information of receiving frame sync identification server 1 simultaneously records the timestamp for receiving return information, and determines frame synchronization service
The difference of time shaft between device 1 and frame synchronization time service server 3；
Frame synchronization time service server 1, the frame synchronization time service server for after receiving UDP information, when will receive UDP information
1 timestamp is added to behind UDP information and sends back frame synchronization server 2；
Client 3, receives the information of each frame synchronization server 2, and according to the difference of time shaft by the operation information of user
Time converts the time on framing synchronization time service server time axis.
In accordance with the invention it is possible to establish a central frame synchronization time service server 1, all frame synchronization servers 2 exist
The detection that the difference of respective system time is carried out with frame synchronization time service server 1 is required after starting.Frame synchronization server 2 is to frame
Sync identification server 1 sends the UDP information for carrying oneself current time stamp, and frame synchronization time service server 1 receives UDP letter
The timestamp of oneself when receiving information is attached to behind information at once after breath and sends back to the frame synchronization of this information source at once
Server 2.Frame synchronization server 2 records the current time after receiving the return information of frame synchronization time service server 1.Such as Fig. 2 institute
Show thus there are three timestamps: the system time T1 and T3 of frame synchronization server 2 oneself, frame synchronization time service server 1
Time t2.The time sequencing occurred according to information communication, it can be appreciated that T1 < t2 < T3, but now existing is two clothes
The time shaft of business device centainly has a T2 time to be corresponding to it so time frame sync server 2 occurs in t2, and T1 < T2 <
T3.So when looking for an interpolation T2 that can find frame synchronization server and frame synchronization time service server system between T1 and T3
Between time shaft deviation, and this deviation < T3-T1.It is T2 that in realization process, we, which generally take the median of T1 and T3,
That is T2=(T1+T3)/2, and the time difference between T1 and T3 is reduced by handling and replying relevant information as soon as possible.When
Time difference between T1 and T3 is enough small, when for example, 100ms, then the error of T2 and t2 can be in 50ms or so,
In the transmission error range that can be player's receiving.And since respective client is sent out under single frame synchronization server mode
Be sent to the network delay of frame synchronization server be all it is discrepant, what this error was existed in using single frame synchronization server
In client.
It is each after the difference (T2-t2) of time shaft of frame synchronization server 2 and frame synchronization time service server 1 has been determined
A frame synchronization server 2 can be converted framing synchronization time service when receiving and forwarding the operation information of distributed user
Time on 1 time shaft of server, and this error be it is constant, will not accumulate.This is just quite with all users one
The calibration and forwarding operated on platform frame synchronization server, only its time shaft is on the basis of frame synchronization time service server
Virtual time shaft.
Client only will receive the information of a frame synchronization server, Er Qiexin under the mode of single frame synchronization server
Breath is strictly temporally to sort, so client only needs the game synchronized by relevant information to calculate.And root
The information of multiple frame synchronization servers 2 can be received in the Client using multiple frame synchronization servers 2 according to the present invention,
And the time shaft of each frame synchronization server because the reason of respective error and Network Transmission Delays will lead to be sent to it is each
The player exercises information of client can not be stringent it is orderly.So client cannot directly handle these information, and should be first
Each information is cached and is sorted by the timestamp of carrying, and by all frame synchronization servers 2 buffering queue some
Relevant calculating is carried out again after all synchronizing informations before time are all complete.Calculating progress is by last always in this way
The frame synchronization server of a arrival drives.As shown in figure 3, the T1 information of frame synchronization server 1 just arrives to, frame synchronization service
Device 2 has had sent the information of T1 and T2 frame, while frame synchronization server 3 has been transmitted across the information of T1, T2 and T3 frame.
Those of ordinary skill in the art will appreciate that: the foregoing is only a preferred embodiment of the present invention, and does not have to
