Description
Technical field
The present invention relates to field of data communication, more particularly to a kind of transregional data communications method and system further include one kind
Data age control device and method for synchronizing time.
Background technology
With the sustainable development of IT industry, more affairs are included into IT system and are handled in enterprise, each inside IT system
There are more and more communications between a server to connect.Since the processing of each application is all that time-effectiveness controls, hair
As soon as the instruction gone out fails to be handled in predefined time range, data originating end will be considered that the data have failed.
But since data need to flow through multiple processing links, when performance fault occur in wherein one or more links, will cause between application
The timeliness for being transmitted the communication packet of processing has failed, and can still need to using the thing processed, and the final data that generate differ
Cause or production development accident.
Such as：Bank ATM initiates a transaction of withdrawing the money, if since host is busy, this data processing request is in master
Overlong time in machine processing waiting list, alreadys exceed the business processing term of validity, and ATM is because time-out has been abandoned waiting for, specifically
Transaction data ought to be discarded.But according to currently used data age treatment mechanism, this transaction data is finally still by host
It manages and carries out button account, this withdrawal data are still handled in each intermediate links, are judged as in ATM machine by ATM until returning
This withdrawal data have timed, out and discard.In addition, ATM also needs to automatically initiate the positive request of a punching again, to allow host
The button account update completed before retracting.So currently used data age treatment mechanism waste efficient resource.
In addition, also by taking ATM withdraws the money as an example, after the positive transaction of ATM withdrawals is sent out, withdrawal data lag, which reaches, because of various reasons leads
Machine, and before positive transaction data of withdrawing the money reaches host, ATM is because wait for time-out to have issued the positive request of withdrawal punching, due to each
The treatment mechanism of node is different, and correction data request is rushed in withdrawal to reach host earlier than positive transaction of withdrawing the money, then this punching of withdrawing the money
Correction data request meeting processing failure (because can not find the positive transaction record of this withdrawal on host), the withdrawal then reached is just merchandised
But account is carried out by host and is had updated, the positive transaction of punching is there will be no in this withdrawal, causes to cause account mistake.
Existing data age control function, is typically limited to only internal system, it is impossible to which cross-system operation needs outer
The supports such as portion's clock synchronization.This data control mode, in the data handling procedure across time zone or each intermediate-node services
During the Time Inconsistency of device, it is difficult to ensure the timeliness of data.Therefore, it is necessary to a kind of new data age control device and do
Method in the data handling procedure of various scenes, can carry out self-correcting, ensure the energy saving correct invalid report of identification of each communication link

The data of effect property will be abandoned.It is a sample calculation as follows：
Timestamp in stream compression time=local zone time+time zone conversion+time difference-data
If the stream compression time is more than the data effective period in data, then it is assumed that this data are invalid datas；It is false
If the stream compression time is less than the data effective period in data, then it is assumed that this data are valid data.
Step 405：The data for meeting timeliness requirement are handled by data processing equipment 1；
Step 406：After the processing of data processing equipment 1, the data of return data originating end 8 are needed, it will be again by the first data
Timeliness control device 2 carries out timeliness processing, inserts temporal information；
Step 407：First data sending device, 4 transmission data；
Step 408：Second data sink 7 receives data；
Step 409：Second data age processing unit 5 carries out timeliness judgement to receiving data, does not meet timeliness
The data of property will be abandoned.It is a sample calculation as follows：
Timestamp in stream compression time=local zone time+time zone conversion+time difference-data
If the stream compression time is more than the data effective period in data, then it is assumed that this data are invalid datas；It is false
If the stream compression time is less than the data effective period in data, then it is assumed that this data are valid data.
Step 410：Data that data originating end 8 receives that treated, for the functions such as specifically showing.
This embodiment reduces the resource consumption that server handles invalid data, and server is reduced because handling invalid number
According to the inconsistent risk of the data brought.ATM retransmits the positive request of punching after a data effective period is waited for, even if withdrawal request
Host is reached after specific impulse just request, withdrawal request message is as be decidedly superior to effective period and abandoned by host, account
It will not be updated, across time zone or each node server time irreversibility, in the case of discrepant, ensure that application system
Robustness, ensure that the validity of data.

The temporal information for the communicating pair that handshake elements obtain；
Timeliness control unit, including timestamp processing module and timeliness judgment module, the timestamp processing module is used for needing
The data to be sent add in timestamp information；Wherein, the timestamp information includes the server time acquiring unit
The information obtained with the time-out information acquiring unit；The time that the timeliness judgment module is used in the data according to acquisition believes
The temporal information recorded in breath and temporal information storage unit carries out timeliness judgement to the data of acquisition；
It further includes：Temporal information synchronization unit
The temporal information synchronization unit is sent to other back end for tissue message, reacquire communicating pair when
Between information, carry out automatic synchronization and correction to the temporal information of communicating pair, and by the time information renovation of acquisition to it is described when
Between information memory cell；
Time-zone information where the timestamp information includes transmission data end, local sending time, data effective periods.
6. a kind of method for synchronizing time, which is characterized in that this method is based on the data age control device described in claim 5
It carries out, the method for synchronizing time includes：
Configuration file is read by the time-out information acquiring unit, completes the initialization behaviour of the data age control device
Make；
Initial handshake unit carries out shaking hands for application layer with communication counterpart, the time letter needed described in both sides during exchanging operation
Breath, and the temporal information of acquisition is written to temporal information storage unit；
Temporal information synchronization unit periodically starts, and is exchanged with communication counterpart, reacquires the temporal information of communicating pair, right
The temporal information of communicating pair carries out automatic synchronization and correction, and the time information renovation of acquisition is stored to the temporal information
Unit.
7. method as claimed in claim 6, which is characterized in that the initial handshake unit carries out application layer with communication counterpart
The step of shaking hands includes：
The side that communicates initiates handshake request to communication counterpart；
The communication counterpart returns to response to one side of the communication；
The response sending application that one root of the communication is returned according to communication counterpart is referred to as to the communication counterpart；
Local time information is sent to one side of the communication by the communication counterpart；
One side of the communication registers the temporal information of the communication counterpart, and local time information is sent to the communication pair
Side；
The temporal information of the communication counterpart registration one side of the communication.
