Embodiment
The design point of the present invention is：During by recorded message by data network transmission, into data network
Timestamp, and the default maximum delay of setting makes message when being transferred to message reception device, meeting
It could export, be led so as to avoid message and be transmitted in the case where being not unrestricted in the case of output time
The uncertain problem of transmission time of cause, message must postpone default this duration of maximum delay, convenient follow-up
Operation and expand the application of data network.
Each embodiment of the invention is described further below in conjunction with the accompanying drawings.
A kind of file transmitting method is present embodiments provided, Fig. 1 is refer to, including：
S101, generation message；
When S102, recorded message enter data network, the timestamp of inlet clock；Wherein, inlet clock with
Outlet clock is synchronous；
S103, timestamp is sent to message reception device together with message by data network.
In S101, the message of packet transmission device generation, not necessarily packet transmission device is generated in itself,
Can also be sent to packet transmission device after other devices are generated；Packet transmission device is that message passes through number
The starting point sent according to network, message enters data network in packet transmission device this point.
In S102, because packet transmission device sends message by data network, and packet transmission device
The starting point of data network again, send when, record message into data network when, inlet clock when
Between stab, and the timestamp is corresponding with the message.The place for entering data network in message sets an entrance
Clock, the inlet clock is used for the time that real-time recorded message enters data network.
The registration accuracy of inlet clock can be very high, that is, be accurate to the moment that message enters data network, that is, remember
Time under record at that time；Precision is higher, and the fluctuation of passing time is just smaller.For the shape of clock in this implementation
Formula, in other words principle do not limit, either mechanical clock, or electronic clock, quartz clock, atomic clock etc.,
All it is feasible.
Due to needing recorded message dispensing device to send the time of message, and message reception device receives message
Time, then, the time of inlet clock and outlet clock should be synchronous；Synchronization is meant that, or is entered
Mouthful clock be with the time of outlet clock it is consistent, or inlet clock time and outlet clock time it
Between conversion relation be to determine.For example, the areas of time zone Shi Dong eight where Beijing, the time zone where Tokyo is
Eastern 9th area, then, just there is the time difference of a hour between Pekinese's time and the time in Tokyo；Therefore, if
Packet transmission device is in Beijing, and message reception device is in Tokyo, then the timestamp of record just should
A hour is subtracted plus the time of a hour, or outlet clock, can thus make both synchronous.
The method of synchronization of inlet clock and outlet clock, can have a variety of；In general, the synchronization side of clock
Formula is divided into two major classes, first, synchronized between outlet clock and inlet clock, i.e., with outlet clock/enter
On the basis of mouth clock, make inlet clock/outlet clock consistent therewith；So synchronous result is two clocks
Absolute time might not be accurate, but the realization of the present embodiment is not influenceed；Second, be outlet clock and
Inlet clock is synchronized with reference clock, i.e., on the basis of the clock of a third-party standard, use
Mouth clock and inlet clock are synchronous with the reference clock, accordingly, between outlet clock and inlet clock
Just it is synchronized.Specifically, synchronous mode can include：GPS (Global Positioning System,
Global positioning system), NTP (Network Time Protocol, NTP), the Chinese Big Dipper defends
Star navigation system, atomic clock, IEEE1588 (the precision interval clock synchronous protocol marks of network measure and control system
It is accurate) etc. any synchronous mode.
In S103, now packet transmission device has obtained timestamp corresponding with message；During for this
Between stab and can be learnt by message reception device, accordingly, it would be desirable to which the timestamp and message are passed through into data network together
Network is sent.Why to send together, be in order to avoid message and timestamp are connect while reaching message
Receiving apparatus, so as to be made troubles to comparison.But, in a general case, even if when corresponding with message
Between stamp with message be not at the same time arrival message reception device, for the present embodiment realization there will not be it is too big
Influence.
Optionally, have recorded message into data network timestamp after, the timestamp is just inserted into report
Wen Zhong, so ensures that message and corresponding timestamp can be while reach message reception device.Tool
Body, multiple positions that the timestamp may be inserted into message, such as header, header and effectively in
Between appearance, or message afterbody.
Message adds timestamp this data in original content, it is thus typically necessary to message again
Encapsulation；Resealing here, includes but is not limited to：Recalculate message length content, recalculate report
CRC (Cyclic Redundancy Code, CRC) check byte of text etc..Again to message
After being Resealed, it is possible to be smoothly sent to the message after encapsulation and be sent to by data network
Message reception device, is then handled message by message reception device.
A kind of message method of reseptance is present embodiments provided, Fig. 2 is refer to, including：
S201, the timestamp for receiving by data network inlet clock when message and message enter data network；
S202, according to timestamp and default maximum delay, determine the output time of message；
If the time point of S203, outlet clock is less than output time, message is cached, outlet clock
It is synchronous with inlet clock.
In S201, it is the message sent naturally by data network to receive message；What message was sent
What the time was not to determine, the time spent in and time of arrival be not to determine that this is due to data network
Network itself does not have the transmission time of a determination.And timestamp be exactly message enter data network when, entrance
The time of clock.
Optionally, timestamp and message are sent by data network together, i.e., timestamp and message be simultaneously
Reach message output device；Why to send together, be in order to avoid message and timestamp are not simultaneously
Message reception device is reached, so as to be made troubles to comparison.But, in a general case, though with report
The corresponding timestamp of text is not to reach message reception device at the same time with message, for the realization of the present embodiment
Do not have too much influence.
In S202, the corresponding timestamp of message received is removed, maximum delay and outlet clock is also preset
Time point.The time point of outlet clock is it is well understood that be exactly the time suggested by outlet clock.During outlet
Clock is similar with inlet clock, and its precision can be very high, and precision is higher, and the time of message transmission is more accurate,
More message can be made to be exported with expected time delay；To the form of clock in the present embodiment, principle does not have in other words
Limit, either mechanical clock, or electronic clock, quartz clock, atomic clock etc., is all feasible.
According to timestamp corresponding with message and default maximum delay, the output time of message is determined；And report
The output time of text includes：Output time is more than or equal to timestamp and default maximum delay sum.Output time
Refer to a time point, message be allowed to more than or equal to timestamp and default maximum time sum this
One time point was output, and was also allowed to be output more than timestamp and the time point of default maximum time sum；
Although output time is a time point, but is not meant to that message is bound to export at this moment, true
On, output time is the earliest time point that message allows to be output, and optimal time point, it is ensured that report
From being sent to, output can pass through one section of regular time to text and this regular time is also short as far as possible, protect
Efficiency is demonstrate,proved.
Default maximum delay has been also discussed above.Because the time that message is transmitted in a data network is not fixed,
Therefore, a fixed default maximum delay is set in the present embodiment to it, during by this default maximum
Prolong so that message is fixed from time of the output between this is sent to, be exactly default maximum delay.Preset most
Long time delay is exactly a kind of time that is default, making message delay fixation duration.As a rule, although data network
Its transmission time of the message transmitted in network is not fixed, but the general maximum for having a transmission time, i.e.,
Maximum delay time；And in normal transmitting procedure, message is passed not over this maximum delay time
The defeated time is smaller than this maximum delay time.The maximum delay time is usually experimental data, i.e.,
Determined by multiple repairing weld, from packet transmission device to message reception device, under normal circumstances, message
That value that time delay maximum is no more than.Default maximum delay in the present embodiment, typically just refers to this
Maximum delay time, this can ensure, the time that message is transmitted in a data network is default most not over this
Long time delay, therefore, just can by message from be sent to output this period be fixed up, reduction do not produce even
Fluctuation, makes the transmission of message more stablize.Certainly, default maximum delay can also according to demand be tuned up and turned down,
As long as it is in rational scope.
In S203, when being less than output time at the time point of outlet clock, message is cached.Need
Bright, the time point of outlet clock, not just message reach the time of message reception device at that moment,
What it referred to is exactly the time suggested on outlet clock；Because the time suggested by outlet clock is to exist always
In passage, therefore, when the time point of outlet clock is less than output time, it should which the progress continued for is compared
It is right.If the time point of outlet clock is less than output time, then when reaching output at the time point of outlet clock
During quarter, it is possible to outgoing message；If the time point of outlet clock is more than output time, it is possible to directly export
Message.In other words, when being less than output time at the time point of outlet clock, output time is exactly the true of message
The real time outwards exported；When being more than output time at the time point of outlet clock, it is possible to which directly output is reported
Text.
When message has just reached message reception device, it is clear that now time point of outlet clock, in other words
The time of outlet clock prompting and the difference of timestamp, are exactly the time that message is transmitted in a data network.Above
It is known that this time is not fixed, it often floats, therefore, and the present embodiment has
The concept of default maximum delay；If just right always if the time point of outlet clock is less than output time always
The message is cached.And during caching, the time point of outlet clock can become closer to output time,
And when being equal to output time at the time point of outlet clock, it is possible to export the message.
Further, since timestamp is the time of inlet clock, therefore, outlet clock should be same with inlet clock
Step；Synchronization is meant that either inlet clock is consistent or inlet clock with the time of outlet clock
Time and outlet clock time between conversion relation be to determine.
The method of synchronization between outlet clock and inlet clock, can have a variety of；In general, clock is same
Step mode is divided into two major classes, first, being to be synchronized between outlet clock and inlet clock, i.e., when to export
On the basis of clock/inlet clock, make inlet clock/outlet clock consistent therewith；So synchronous result is two
The absolute time of clock might not be accurate, but the realization of the present embodiment is not influenceed, as long as both it
Between time synchronized；Second, being that outlet clock and inlet clock are synchronized with reference clock, i.e.,
On the basis of the clock of a third-party standard, make outlet clock and inlet clock same with the reference clock
Step, accordingly, is also just synchronized accordingly between outlet clock and inlet clock.Specifically, synchronous side
Formula can include：GPS, NTP, Chinese Beidou satellite navigation system, atomic clock, IEEE1588 etc. are any
Synchronous mode.
In outgoing message, if timestamp is packaged in message, need to move the timestamp in message
Remove, then message is Resealed and exported again.Reseal including but not limited to：Recalculate message
Lengthy content, the CRC check byte for recalculating message etc..
The message of output can be output to required place, so as to realize required function；In the present embodiment,
It is consistent from output elapsed time is sent to that message, which can be made, in other words, as long as sending message
When, to have the message of sequential set sequencing, that ensure that message output when, its be also according to
What default sequential was exported.For same message reception device, when sending, two are set
Sequential between message, after the transmission by data network, even if the message first sent is received afterwards, also can
But do not meet the requirement of output time because the message sent afterwards is arrived first and be buffered, allow for what is first sent
Message still can guarantee that and first be exported；And the message for having sequential is sent to different messages by packet transmission device
Reception device is also the same, and sequential when equally ensure that sequential when message is sent with reception is consistent, from
And make user's operation easier and reliable.
A kind of message processing method is present embodiments provided, Fig. 3 is refer to, including：
S301, generation message；
When S302, recorded message enter data network, the timestamp of inlet clock；Wherein, inlet clock with
Outlet clock is synchronous；
Timestamp is sent to message by data network together with message and receives dress by S303, packet transmission device
Put；
S304, pass through data network and receive message and timestamp；
S305, the output time for determining according to timestamp and default maximum delay message；
If the time point of S306, outlet clock is less than output time, message is cached, outlet clock
It is synchronous with inlet clock.
In S301, the message of packet transmission device generation, not necessarily packet transmission device is generated in itself,
Can also be sent to packet transmission device after other devices are generated；Packet transmission device is that message passes through number
The starting point sent according to network, message enters data network in packet transmission device this point.
In S302, because packet transmission device sends message by data network, and packet transmission device
The starting point of data network again, send when, record message into data network when, inlet clock when
Between stab, and the timestamp is corresponding with the message.The place for entering data network in message sets an entrance
Clock, the inlet clock is used for the time that real-time recorded message enters data network.
The registration accuracy of inlet clock can be very high, that is, be accurate to the moment that message enters data network, that is, remember

Time, then, the time of inlet clock and outlet clock should be synchronous；Synchronization is meant that, or is entered
Mouthful clock be with the time of outlet clock it is consistent, or inlet clock time and outlet clock time it
Between conversion relation be to determine.For example, the areas of time zone Shi Dong eight where Beijing, the time zone where Tokyo is
Eastern 9th area, then, just there is the time difference of a hour between Pekinese's time and the time in Tokyo；Therefore, if
Packet transmission device is in Beijing, and message reception device is in Tokyo, then the timestamp of record just should
A hour is subtracted plus the time of a hour, or outlet clock, can thus make both synchronous.
The method of synchronization of inlet clock and outlet clock, can have a variety of；In general, the synchronization side of clock
Formula is divided into two major classes, first, synchronized between outlet clock and inlet clock, i.e., with outlet clock/enter
On the basis of mouth clock, make inlet clock/outlet clock consistent therewith；So synchronous result is two clocks

Inlet clock is synchronized with reference clock, i.e., on the basis of the clock of a third-party standard, use
Mouth clock and inlet clock are synchronous with the reference clock, accordingly, between outlet clock and inlet clock
Just it is synchronized.Specifically, synchronous mode can include：GPS, NTP, Chinese Beidou satellite navigation system,
Any synchronous mode of atomic clock, IEEE1588 etc..
In S303, now packet transmission device has obtained timestamp corresponding with message；During for this

CRC check byte of text etc..After being Resealed again to message, it is possible to smoothly by after encapsulation
Message is sent to is sent to message reception device by data network, and then message is entered by message reception device
Row processing.
In S304, it is the message sent naturally by data network to receive message；What message was sent
What the time was not to determine, the time spent in and time of arrival be not to determine that this is due to data network

When, to have the message of sequential set sequencing, that ensure that message output when, its be also according to
What default sequential was exported.For same message reception device, when sending, two are set
Sequential between message, after the transmission by data network, even if the message first sent is received afterwards, also can
But do not meet the requirement of output time because the message sent afterwards is arrived first and be buffered, allow for what is first sent
Message still can guarantee that and first be exported；And the message for having sequential is sent to different messages by packet transmission device
Reception device is also the same, and sequential when equally ensure that sequential when message is sent with reception is consistent, from
And make user's operation easier and reliable.
A kind of packet transmission device is present embodiments provided, Fig. 4 is refer to, including：
Message generation module 101, for generating message；
Time logging modle 102, when recorded message enters data network, the timestamp of inlet clock；Wherein,
Inlet clock is synchronous with outlet clock；
Message sending module 103, message reception device is sent to by timestamp together with message by data network.
The message that message generation module 101 is generated, not necessarily packet transmission device is generated in itself,
Can be sent to packet transmission device after other devices are generated；Message sending module 103 is that message passes through
The starting point that data network is sent, message enters data network in packet transmission device this point.
Because message sending module 103 sends message by data network, and message sending module 103
It is the starting point of data network again, when sending, time logging modle 102, which needs to record message, enters data
During network, the timestamp of inlet clock, and the timestamp is corresponding with the message.Enter data network in message
Network place set an inlet clock, the inlet clock be used for real-time recorded message enter data network when
Between.
The registration accuracy of inlet clock can be very high, that is, be accurate to the moment that message enters data network, that is, remember
Time under record at that time；Precision is higher, and the fluctuation of passing time is just smaller.For the shape of clock in this implementation
Formula, in other words principle do not limit, either mechanical clock, or electronic clock, quartz clock, atomic clock etc.,
All it is feasible.
Due to needing recorded message sending module 103 to send the time of message, and message reception device is received
The time of message, then, the time of inlet clock and outlet clock should be synchronous；It is synchronous to be meant that, or
Person's inlet clock be with the time of outlet clock it is consistent, or inlet clock time and outlet clock when
Between between conversion relation be to determine.For example, where the areas of time zone Shi Dong eight where Beijing, Tokyo when
The areas of area Shi Dong nine, then, just there is the time difference of a hour between Pekinese's time and the time in Tokyo；Therefore,
If packet transmission device is in Beijing, and message reception device is in Tokyo, then the timestamp of record just should
A hour should be subtracted plus a hour, or the time of outlet clock, and can thus make both synchronous.
The method of synchronization of inlet clock and outlet clock, can have a variety of；In general, the synchronization side of clock
Formula is divided into two major classes, first, synchronized between outlet clock and inlet clock, i.e., with outlet clock/enter
On the basis of mouth clock, make inlet clock/outlet clock consistent therewith；So synchronous result is two clocks
Absolute time might not be accurate, but the realization of the present embodiment is not influenceed；Second, be outlet clock and
Inlet clock is synchronized with reference clock, i.e., on the basis of the clock of a third-party standard, use
Mouth clock and inlet clock are synchronous with the reference clock, accordingly, between outlet clock and inlet clock
Just it is synchronized.Specifically, synchronous mode can include：GPS, NTP, Chinese Beidou satellite navigation system,
Any synchronous mode of atomic clock, IEEE1588 etc..
Now time logging modle 102 has obtained timestamp corresponding with message；For this timestamp
It can be learnt by message reception device, accordingly, it would be desirable to which the timestamp and message are sent out by data network together
Send.Why to send together, be in order to avoid message and timestamp are not while reaching message receives dress
Put, so as to be made troubles to comparison.But, in a general case, even if timestamp corresponding with message
It is not to reach message reception device at the same time with message, the realization for the present embodiment there will not be too big shadow
Ring.
Optionally, in addition to the first package module 1031, for have recorded message into data network when
Between stab after, just the timestamp is inserted into message, message is so ensured that and the corresponding time
Stamp can reach message reception device simultaneously.Specifically, multiple positions that the timestamp may be inserted into message,
As between header, header and effective content, or message afterbody.
Message adds timestamp this data in original content, it is thus typically necessary to message again
Encapsulation；Resealing here, includes but is not limited to：Recalculate message length content, recalculate report
CRC check byte of text etc..After being Resealed again to message, it is possible to smoothly by after encapsulation
Message is sent to is sent to message reception device by data network, and then message is entered by message reception device
Row processing.
A kind of message reception device is present embodiments provided, Fig. 5 is refer to, including：
Message receiving module 201, enters during for receiving message and message into data network by data network
The timestamp of mouth clock；
Time determining module 202, for according to timestamp and default maximum delay, when determining the output of message
Carve；
Packet buffer module 203, if the time point for outlet clock is less than output time, is carried out to message
Caching, outlet clock and inlet clock are synchronous.
Message receiving module 201 receives the message sent naturally by data network；Message is sent
Time be not to determine, the time spent in and time of arrival be not to determine that this is due to data
Network itself does not have the transmission time of a determination.And timestamp be exactly message enter data network when, enter
The time of mouth clock.
Optionally, timestamp and message are sent by data network together, i.e., timestamp and message be simultaneously
Reach message receiving module 201；Why to send together, be in order to avoid message and timestamp are not same
When reach message receiving module 201, so as to be made troubles to comparison.But, in a general case, even if
Timestamp corresponding with message is not to reach message receiving module 201 at the same time with message, for the present embodiment
Realization there will not be too much influence.
The corresponding timestamp of message received is removed, the time point of maximum delay and outlet clock is also preset.
The time point of outlet clock is it is well understood that be exactly the time suggested by outlet clock.When outlet clock is with entrance
Clock is similar, and its precision can be very high, and precision is higher, and the time of message transmission is more accurate, more can make report
Text is exported with expected time delay；To the form of clock in the present embodiment, principle is not limited in other words, no
Pipe is mechanical clock, or electronic clock, quartz clock, and atomic clock etc., is all feasible.
According to timestamp corresponding with message and default maximum delay, the output time of message is determined；And report
The output time of text includes：Output time is more than or equal to timestamp and default maximum delay sum.Output time
Refer to a time point, message be allowed to more than or equal to timestamp and default maximum time sum this
One time point was output, and was also allowed to be output more than timestamp and the time point of default maximum time sum；
Although output time is a time point, but is not meant to that message is bound to export at this moment, true
On, output time is the earliest time point that message allows to be output, and optimal time point, it is ensured that report
From being sent to, output can pass through one section of regular time to text and this regular time is also short as far as possible, protect
Efficiency is demonstrate,proved.
Default maximum delay has been also discussed above.Because the time that message is transmitted in a data network is not fixed,
Therefore, a fixed default maximum delay is set in the present embodiment to it, during by this default maximum
Prolong so that message is fixed from time of the output between this is sent to, be exactly default maximum delay.Preset most
Long time delay is exactly a kind of time that is default, making message delay fixation duration.As a rule, although data network
Its transmission time of the message transmitted in network is not fixed, but the general maximum for having a transmission time, i.e.,
Maximum delay time；And in normal transmitting procedure, message is passed not over this maximum delay time
The defeated time is smaller than this maximum delay time.The maximum delay time is usually experimental data, i.e.,
Determined by multiple repairing weld, from packet transmission device to message reception device, under normal circumstances, message
That value that time delay maximum is no more than.Default maximum delay in the present embodiment, typically just refers to this
Maximum delay time, this can ensure, the time that message is transmitted in a data network is default most not over this
Long time delay, therefore, just can by message from be sent to output this period be fixed up, reduction do not produce even
Fluctuation, makes the transmission of message more stablize.Certainly, default maximum delay can also according to demand be tuned up and turned down,
As long as it is in rational scope.
Because timestamp is the time of inlet clock, therefore, outlet clock should be synchronous with inlet clock；Together
Step is meant that either inlet clock and the time of outlet clock are consistent or inlet clock time
What the conversion relation between the time of outlet clock was to determine.
The method of synchronization between outlet clock and inlet clock, can have a variety of；In general, clock is same
Step mode is divided into two major classes, first, being to be synchronized between outlet clock and inlet clock, i.e., when to export
On the basis of clock/inlet clock, make inlet clock/outlet clock consistent therewith；So synchronous result is two
The absolute time of clock might not be accurate, but the realization of the present embodiment is not influenceed, as long as both it
Between time synchronized；Second, being that outlet clock and inlet clock are synchronized with reference clock, i.e.,
On the basis of the clock of a third-party standard, make outlet clock and inlet clock same with the reference clock
Step, accordingly, is also just synchronized accordingly between outlet clock and inlet clock.Specifically, synchronous side
Formula can include：GPS, NTP, Chinese Beidou satellite navigation system, atomic clock, IEEE1588 etc. are any
Synchronous mode.
When being less than output time at the time point of outlet clock, packet buffer module 203 is just delayed to message
Deposit.It should be noted that the time point of outlet clock, not just message reach message receiving module 201
Time at that moment, what it referred to is exactly the time suggested on outlet clock；By being carried for outlet clock
The time shown is always in passage, therefore, when the time point of outlet clock is less than output time, it should
What is continued for is compared.Optionally, in addition to message output module 204, for when outlet clock
Between point be less than output time, then when reaching output time at the time point of outlet clock, it is possible to output report
Text；It is more than output time when the time point of outlet clock, it is possible to direct outgoing message.In other words, going out
When the time point of mouth clock is less than output time, output time is exactly the true time outwards exported of message；
When being more than output time at the time point of outlet clock, it is possible to direct outgoing message.
When message has just reached message receiving module 201, it is clear that now time point of outlet clock, or
Person explains the time of clock prompting and the difference of timestamp, is exactly the time that message is transmitted in a data network.
Above it is known that this time is not fixed, it often floats, therefore, the present embodiment
There is the concept of default maximum delay；If the time point of outlet clock always be less than output time if, just by
Packet buffer module 203 is cached to the message always.And during caching, the time point of outlet clock
Output time can be become closer to, and when being equal to output time at the time point of outlet clock, it is possible to by reporting
Literary output module 204 exports the message.
Optionally, message output module 204 also includes the second package module 2041, if being envelope for timestamp
Fill in messages, then need to remove the timestamp in message, then message is Resealed again defeated
Go out.Reseal including but not limited to：Recalculate message length content, recalculate the CRC schools of message
Test byte etc..
The message of output can be output to required place, so as to realize required function；In the present embodiment,
It is consistent from output elapsed time is sent to that message, which can be made, in other words, as long as sending message
When, to have the message of sequential set sequencing, that ensure that message output when, its be also according to
What default sequential was exported.For same message reception device, when sending, two are set

Message still can guarantee that and first be exported；And the message for having sequential is sent to different messages by packet transmission device
Reception device is also the same, and sequential when equally ensure that sequential when message is sent with reception is consistent, from
And make user's operation easier and reliable.
