Detailed description of the invention
Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The main solution technical scheme of the embodiment of the present invention is: a kind of can the privately owned order of self-defined SATA transmission association
View, carrying out the product for any employing SATA interface provides privately owned communication interface, can be reduced by this kind of mode and be made at present
Publicly-owned order on the basis of " privately owned communication interface " difficulty of developing, and the probability of miscarriage of justice of privately owned order communication from former
Reduce to 0 in reason, improve the accuracy of protocol communication.
, easily there is logical data and the erroneous judgement of privately owned order in existing communication protocol mode, to reduce this erroneous judgement,
Need in first terminal, increase some a little complicated controls and judgment mechanisms, therefore can increase certain maintenance cost.
Based on the problems referred to above, the present invention provides a kind of message communication method.
With reference to the schematic flow sheet that Fig. 1, Fig. 1 are message communication method first embodiment of the present invention.
The present embodiment proposes a kind of message communication method, and described message communication method includes:
Step S10, first terminal is when receiving the command message that the second terminal sends, at the message of described command message
Command token mark is extracted in Tou；
Step S20, described first terminal determines the type of the described command token mark of extraction；
In the present embodiment, first terminal is when receiving the command message that the second terminal sends, first at described order report
The heading of literary composition extracts command token mark, then the described command token mark extracted is analyzed, to determine
Stating the type of command token mark, the type of the command property field in identifying specifically according to described command token is carried out really
Fixed, when the type of command property field is privately owned command property field, it may be determined that described command token is designated privately owned order
Token identifications.
Step S30, the type that described command token identifies be privately owned command token mark time, described first terminal based on
Described privately owned command token mark obtains reply data；
Step S40, described first terminal generates response message according to the described reply data extracted, with by described response report
Literary composition feeds back to described second terminal.
Further, described first terminal based on described privately owned command token mark first preset look-up table extract should
Before the step of answer evidence, described message communication method also includes:
Described first terminal determines current state；
When described current state is idle condition, performs described first terminal and obtain based on described privately owned command token mark
Take the step of reply data；
When described current state is busy state, described first terminal waits message to described second terminal feedback, and
When described current state switches to idle condition from busy state, perform described first terminal based on described privately owned command token
Mark obtains the step of reply data.
In the present embodiment, when the type that described command token identifies is privately owned command token mark, described first eventually
End further determines that the order that described privately owned command token mark is corresponding, wherein, the life that described privately owned command token mark is corresponding
Order has write order or read command etc., in the present embodiment, when the order that described privately owned command token mark is corresponding is read command,
Described first terminal first combines current state, if described first terminal is currently at idle condition, can respond described at once
The privately owned order of two terminals, then obtain reply data according to described read command, in the present embodiment, preferably exist according to described read command
First presets acquisition reply data in look-up table, and the described reply data obtained is added the heading to described response message
In, the response message being added with described reply data to be fed back to described second terminal；If described first terminal is currently at
Busy state, it is impossible to respond the privately owned order of described second terminal at once, then can preset to obtain in look-up table first waiting number
According to, and described wait pending data to add to the heading waiting message by extract, with by be added with the pending data such as described etc.
Treat that message feeds back to described second terminal, and when described current state switches to idle condition from busy state, just based on institute
State privately owned command token mark and preset look-up table acquisition reply data first, and should according to the described reply data generation obtained
Answer message, described response message to be fed back to described second terminal.
For being best understood from this enforcement, it is exemplified below: with reference to Fig. 2, the i.e. main frame of the second terminal sends Register FIS Host
To Device i.e. includes privately owned command token to first terminal i.e. equipment end, described Register FIS Host to Device
The command message of mark, now, described equipment end analyzes described Register FIS Host to Device, described analyzing
When the order of privately owned command token mark correspondence is read command, determine current status information further, if current state
Information is idle, and the most described equipment end presets acquisition reply data look-up table from first, in described reply data i.e. Fig. 2
Data FIS (Data Frame Information Structures, Frame Information Structure, i.e. reply data), and answer described
Answer is according to adding to described command message to feed back to described main frame.After feeding back successfully, described first terminal extracts
The status data of Register FIS Device to Host is to described second terminal, to represent sign off.
In like manner, when the order that described privately owned command token mark is corresponding is write order, described first terminal is the most first tied
Close current state, if described first terminal is currently at busy state, it is impossible to respond the privately owned order of described second terminal at once,
Then can preset in look-up table the pending datas such as extraction first, and the pending data such as described be added to waiting in message and feed back to second
Terminal, until described first terminal is currently at idle condition, then carries in described first preset table according to described read command
Take reply data, and reply data is added to feed back to described second terminal in response message, for described second terminal
Send and wait to write data in described first terminal, to complete the operation of write order.In like manner, after data write successfully, described
One terminal sends Register FIS Device to Host extremely described second terminal, to represent sign off.
In the present embodiment, in order to improve the accuracy of message communication, with reference to Fig. 3, described step S30 includes:
Step S31, when the type that described command token identifies is privately owned command token mark, described first terminal is by institute
The privately owned command token mark stating privately owned command token mark and prestore is compared；
Step S32, when mating there being the privately owned command token prestored mark to identify with described privately owned command token, described the
One terminal obtains the reply data that described privately owned command token mark is corresponding.
In the present embodiment, when the type that described command token identifies is privately owned command token mark, described first eventually
Hold by extract described privately owned command token mark with described first preset the privately owned command token prestored in look-up table identify into
Row comparison, only presets described first and has the privately owned command token mark prestored and the described privately owned command commands extracted in look-up table
During board mark coupling, described first terminal is just preset look-up table based on described privately owned command token mark first and is obtained answer number
According to, if described first preset look-up table does not prestore privately owned command token mark with described privately owned command token identify mate
Time, the most described first terminal is thought that described privately owned command token mark is illegal, is not obtained reply data.May be appreciated
It is that described first terminal and described second terminal message communication to be carried out, both sides need to prestore identical look-up table, therefore send out
First of first terminal described in bright presets look-up table, and to preset look-up table with the second of described second terminal identical, and second presets and look into
Looking for table to describe in detail in embodiments below, therefore, described second presets look-up table and described first presets look-up table as shown in Figure 4,
It is to say, the privately owned command token that described second terminal obtains in presetting search second identifies and sends to described first eventually
During end, described first terminal needs first to judge that first presets look-up table and the most also prestore described privately owned command token mark, if
Prestore described privately owned command token mark, just perform follow-up operation.At the present embodiment, being equivalent to described first terminal increases
One judgment mechanism, need to realize Effective judgement in each level of SATA, as LINKER layer needs to identify that SCSI-FIS is (privately owned
Command token identifies) it is legal FIS type, otherwise can be mistakenly considered Unrecognized FIS types (privately owned
Command token identifies), can realize owing to this judgment mechanism only need to increase part control decision logic at each layer of agreement, so
Will not substantially increase cost.
In this embodiment, when the type that described command token identifies is privately owned command token mark, described first terminal
Described privately owned command token mark is preset the privately owned command token mark prestored in look-up table with described first compare, only
Described privately owned command token mark preset with described first the privately owned command token prestored in look-up table identify mate time, described
First terminal is just preset look-up table based on described privately owned command token mark described first and is obtained reply data, it is therefore prevented that receive
To illegal privately owned command token identify time, also feed back reply data, improve reply data feedback accuracy.
The present embodiment propose protocol communication method, first terminal receive second terminal send command message time,
In the heading of described command message, first extract command token mark, it is then determined that the described command token mark extracted
Type, when the type that described command token identifies is privately owned command token mark, obtains based on described privately owned command token mark
Take reply data, finally generate response message according to the described reply data obtained, described so that described response message is fed back to
Second terminal rather than get second terminal send command message time, if being resolved to identifier first data field
And during identifying code, be considered as that this command message carries is all privately owned order, if be not resolved to mark first data field
When knowing symbol and identifying code, it is believed that what this command message carried is all logical data, thus the response message of feedback is caused to have from machine
By mistake, the present invention extracts command token mark in the heading of described command message, and carries out described command token mark
Resolve, to determine the type that command token identify, final feedback corresponding response message, it is to avoid privately owned order and logical data
Erroneous judgement, thus improve the accuracy of message communication.
Further, in order to improve the motility of message communication, based on first embodiment, message communication side of the present invention is proposed
Second embodiment of method, in the present embodiment, with reference to Fig. 5, described message communication method also includes:
Step S50, when receiving command message communication instruction, the second terminal determines described command message communication instruction pair
The command type answered；
In the present embodiment, step is included before described step S50:
When 1, receiving the privately owned command property field of input in default application programming interfaces, described second terminal root
Privately owned command token mark is generated according to described privately owned command property field；
2, the described privately owned command token mark that described second terminal storage generates.
It should be appreciated that at present all effective FIS-TYPE (i.e. command token mark), such as Fig. 4 in SATA protocol
In 27h (H2D-FIS), be current SATA protocol sends all of order before a FIS type all must sending, we
Case SCSI-FIS function to be added is completely and H2D-FIS is completely the same, i.e. plays and sends " the command token mark " ordered.
Why wanting a newly added SCSI-FIS to be able to differentiation is that H2D-FIS (i.e. distinguishes the mark whether SATA protocol defines
Quasi-order), knowable to accompanying drawing 4, A6, B8, BF etc. are the values retained, and this kind of numeral therefore can be used to represent, and SCSI-FIS is i.e.
Can.Because the function of SCSI FIS is the most consistent with H2D FIS, so SCSI FIS structure is the most the same with H2D FIS, such as figure
Shown in 6, so can the existing logical structure of multiplexing to greatest extent, without increasing new structure, therefore, message communication
Cost also will not increase.
In the present embodiment, when default application programming interfaces receive the privately owned command property field of input, institute
State the second terminal described privately owned command property field to be added to the token identifications template preset, described default application program
Interface is API (Application Programming Interface, application programming interface), say, that the present invention
Described in privately owned command token mark actually the privately owned command property field that user inputs is added to the token mark preset
Knowing generation in template, described token identifications template, with reference to Fig. 6, finally can generate a privately owned command token mark, then deposit
The described privately owned command token mark that storage generates, in like manner, the described privately owned command token mark that described second terminal preferably will generate
Know storage to preset in look-up table to described second.It should be noted that in first terminal also privately owned by input
During command property field add to preset token identifications template in, with generate privately owned command token mark, and, be equally by
The described privately owned command token mark storage generated is preset in look-up table to described first, say, that will realize the second terminal
And the communication between first terminal, needing to appoint between the second terminal and first terminal, follow-up direct basis is reserved in advance
Look-up table communicates.
In the present embodiment, the embodiment of described step S50 includes:
When receiving command message communication instruction, described second terminal is according to the life in described command message communication instruction
Property value is made to determine the command type that described command message communication instruction is corresponding；
Or, when receiving command message communication instruction, described second terminal is according to described command message communication instruction
In control bit determine the command type that described command message communication instruction is corresponding.
It is to say, the command type that described command message communication instruction in the present embodiment is corresponding, it it is the second terminal root
Command property value or control bit according to input are determined, i.e. in order to send self-defining in the application layer of second terminal
Privately owned order, needs the api interface of the second terminal to provide the access rights of FIS Type, and this mode can be (the most i.e.
The directly assignment operation to FIS Type) or indirectly (represented it is self-defining command type by control bit), according to described
Control bit in command property value in command message communication instruction, or described command message communication instruction i.e. can determine that described
The command type that command message communication instruction is corresponding.Such as, the command property value in protocol communication instruction is 27h, it is known that current
Described command type is privately owned order, or represents publicly-owned order at control bit for " 1 ", represents privately owned life at control bit for " 0 "
Order, then described second terminal i.e. can determine that, according to the control bit of input, the order class that described command message communication instruction is corresponding
Type.
Step S60, when described command type is privately owned order, it is corresponding that described second terminal obtains described privately owned order
Privately owned command token identifies, and the described privately owned command token obtained mark is added in the heading of command message；
Step S70, the command message being added with described privately owned command token mark is sent to first by described second terminal
In terminal, in the heading of described command message, extract privately owned command token for described first terminal and identify, and according to
The reply data generation response message that described privately owned command token mark is corresponding, is added with the response report of reply data with feedback
Literary composition.
In the present embodiment, when described command type is privately owned order, described second terminal presets look-up table second
The privately owned command token of middle acquisition identifies, and the described privately owned command token obtained mark is added to the heading of command message
In, then the command message being added with described privately owned command token mark is sent to first terminal, for described first eventually
End extracts privately owned command token mark in the heading of described command message, and right according to described privately owned command token mark
The reply data answered generates response message, is added with the response message of reply data with feedback.
Owing to the definition of current SATA protocol has PIO, (Programming Input/Output Model, CPU perform I/O end
Mouthful instruction read-write data data exchange mode), DMA (Direct Memory Access, direct memory access), FPDMA
Transmission means such as (First Party Direct Memory Access, Party A's direct memory access), wherein PIO transmission is relatively
For DMA and FPDMA, efficiency to compare lowly, and the control of FPDMA transmission means is relative complex, is used under privately owned order communication
Meaning is also little, and the transmission means of FPDMA do not supported by some machine, so using more common DMA transfer mode here,
Therefore, in the present embodiment, the most described second terminal uses DMA transfer mode will to be added with described privately owned command token mark
Command message sends to first terminal, and in like manner, first terminal is also to use DMA transfer mode to feed back response message.
Further, in the present embodiment, described Device i.e. first terminal and Host that is second terminal can be self-defined
Scsi command.Such as in SCSI FIS, Command field 0X50 order represents Write Dma order (i.e. Host to Device
Write the order of data), 0x51 order represents Read Dma order (i.e. the reading data command of Device to host), or permissible
In turn (i.e. 0x50 represents that Read Dma, 0x51 represent write Dma), as long as Host and Device appoints the most permissible.
The message communication method that the present invention proposes, when receiving command message communication instruction, the second terminal determines first institute
State the command type that command message communication instruction is corresponding, when described command type is privately owned order, obtain privately owned command token
Mark, and the described privately owned command token obtained mark is added in the heading of command message, it is added with described the most at last
The command message of privately owned command token mark sends to first terminal, described privately owned based on being added with for described first terminal
The described command message of command token mark, feeds back corresponding response message rather than privately owned command token mark is added extremely
The data field of packet sends to first terminal, it is to avoid when first terminal resolves identifier and identifying code within a data area,
Logical data and the erroneous judgement of privately owned command token bag occur, the present invention improves the accuracy of protocol communication.
It is understood that this programme is equivalent to add in SATA protocol side the new FIS type of SCSI FIS, thus solve
Determine and use publicly-owned order to realize the defect of privately owned order transmission at present, make employing SATA protocol carry out Related product exploitation,
Development cost is reduced, and it is the most convenient to develop.Further, on the architecture basics not changing original SATA communications protocol, add
(Frame Information Structures, privately owned command token bag are herein referred as to add the exclusive FIS TYPE of a class
SCSI-FIS), (the second terminal to first is eventually for the transmission means of this kind of FIS TYPE and the current H2D FIS type of SATA protocol
The communication process of end) similar, it is notable that and this FIS is equivalent to Host and sends the token of order to Deice, the most all
Order transmit all initiated by this FIS, only the present invention is specific to SCSI FIS type, new owing to not increasing
Structure, therefore, the cost of communication reduces.
The present invention further provides a kind of message communication device.

During token identifications coupling, described acquiring unit 32 just presets look-up table acquisition based on described privately owned command token mark first should
Answer evidence, if described first presets the privately owned command token mark and described privately owned command token mark not prestored in look-up table
During coupling, the most described first terminal thinks that described privately owned command token mark is illegal, does not obtain reply data.It is appreciated that
, described first terminal and described second terminal message communication to be carried out, both sides need to prestore identical look-up table, therefore
First of first terminal described in invention presets look-up table, and to preset look-up table with the second of described second terminal identical, and second presets
Look-up table describes in detail in embodiments below, and therefore, described second presets look-up table and described first presets look-up table such as Fig. 4 institute
Show, say, that the privately owned command token that described feedback module 40 obtains in presetting search second identifies and sends to described
During first terminal, described first terminal needs first to judge that first presets look-up table and the most also prestore described privately owned command token mark
Knowing, if prestoring described privately owned command token mark, just performing follow-up operation.At the present embodiment, be equivalent to described first eventually
End increases a judgment mechanism, need to realize Effective judgement in each level of SATA, as LINKER layer needs to identify SCSI-
FIS (privately owned command token mark) is legal FIS type, otherwise can be mistakenly considered Unrecognized FIS types (i.e.
Illegal privately owned command token identifies), control decision logic owing to this judgment mechanism only need to increase part at each layer of agreement
Realize, so cost will not substantially be increased.
In this embodiment, when the type that described command token identifies is privately owned command token mark, described first terminal
Described privately owned command token mark is preset the privately owned command token mark prestored in look-up table with described first compare, only
Described privately owned command token mark preset with described first the privately owned command token prestored in look-up table identify mate time, described
First terminal is just preset look-up table based on described privately owned command token mark described first and is obtained reply data, it is therefore prevented that receive
To illegal privately owned command token identify time, also feed back reply data, improve reply data feedback accuracy.
The present embodiment propose message communication device, first terminal receive second terminal send command message time,
In the heading of described command message, first extract command token mark, it is then determined that the described command token mark extracted
Type, when the type that described command token identifies is privately owned command token mark, obtains based on described privately owned command token mark
Take reply data, finally generate response message according to the described reply data obtained, described so that described response message is fed back to
Second terminal rather than get second terminal send command message time, if being resolved to identifier first data field
And during identifying code, be considered as that this command message carries is all privately owned order, if be not resolved to mark first data field
When knowing symbol and identifying code, it is believed that what this command message carried is all logical data, thus the response message of feedback is caused to have from machine
By mistake, the present invention extracts command token mark in the heading of described command message, and carries out described command token mark
Resolve, to determine the type that command token identify, final feedback corresponding response message, it is to avoid privately owned order and logical data
Erroneous judgement, thus improve the accuracy of message communication.
Further, in order to improve the motility of message communication, based on first embodiment, message communication of the present invention dress is proposed
The second embodiment put, in the present embodiment, with reference to Fig. 9, described message communication device includes:
Second determines module 50, for when receiving command message communication instruction, determines that described command message communication refers to
The command type that order is corresponding；
Processing module 60, for when described command type is privately owned order, obtains corresponding privately owned of described privately owned order
Command token identifies, and the described privately owned command token obtained mark is added in the heading of command message；
Sending module 70, for sending the command message being added with described privately owned command token mark to first terminal
In, in the heading of described command message, extract privately owned command token mark for described first terminal, and according to described
The reply data generation response message that privately owned command token mark is corresponding, is added with the response message of reply data with feedback.
In the present embodiment, described privately owned command token mark is generated by presetting module, and described presetting module includes generating
Module and memory module, wherein:
Described generation module, for receiving the privately owned command property field of input in default application programming interfaces
Time, generate privately owned command token mark according to described privately owned command property field；
Described memory module, for storing the described privately owned command token mark of generation.
It should be appreciated that at present all effective FIS-TYPE (i.e. command token mark), such as Fig. 4 in SATA protocol
In 27h (H2D-FIS), be current SATA protocol sends all of order before a FIS type all must sending, we
Case SCSI-FIS function to be added is completely and H2D-FIS is completely the same, i.e. plays and sends " the command token mark " ordered.
Why wanting a newly added SCSI-FIS to be able to differentiation is that H2D-FIS (i.e. distinguishes the mark whether SATA protocol defines
Quasi-order), knowable to accompanying drawing 4, A6, B8, BF etc. are the values retained, and this kind of numeral therefore can be used to represent, and SCSI-FIS is i.e.
Can.Because the function of SCSI FIS is the most consistent with H2D FIS, so SCSI FIS structure is the most the same with H2D FIS, such as figure
Shown in 6, so can the existing logical structure of multiplexing to greatest extent, without increasing new structure, therefore, message communication
Cost also will not increase.
In the present embodiment, when default application programming interfaces receive the privately owned command property field of input, institute
State generation module described privately owned command property field to be added to the token identifications template preset, described default application program
Interface is API (Application Programming Interface, application programming interface), say, that the present invention
Described in privately owned command token mark actually the privately owned command property field that user inputs is added to the token mark preset
Knowing generation in template, described token identifications template is with reference to Fig. 6, and final described generation module can generate a privately owned command token
Mark, the described privately owned command token mark that the storage of the most described memory module generates, in like manner, described memory module preferably will be raw
The described privately owned command token mark storage become is preset in look-up table to described second.It should be noted that first terminal
In also will input privately owned command property field time add to preset token identifications template in, to generate privately owned order
Token identifications, and, it is that the described privately owned command token generated mark storage is preset in look-up table, also to described first equally
That is, the communication between the second terminal and first terminal to be realized, need to appoint between the second terminal and first terminal,
The look-up table that follow-up direct basis is reserved in advance communicates.
In the present embodiment, described second determines that module 50, when receiving command message communication instruction, determines described life
The embodiment making the command type of message communication instruction correspondence includes:
When receiving command message communication instruction, described second terminal is according to the life in described command message communication instruction
Property value is made to determine the command type that described command message communication instruction is corresponding；
Or, when receiving command message communication instruction, described second terminal is according to described command message communication instruction
In control bit determine the command type that described command message communication instruction is corresponding.
It is to say, the command type that described command message communication instruction in the present embodiment is corresponding, it it is the second terminal root
Command property value or control bit according to input are determined, i.e. in order to send self-defining in the application layer of second terminal
Privately owned order, needs the api interface of the second terminal to provide the access rights of FIS Type, and this mode can be (the most i.e.
The directly assignment operation to FIS Type) or indirectly (represented it is self-defining command type by control bit), according to described
Control bit in command property value in command message communication instruction, or described command message communication instruction i.e. can determine that described
The command type that command message communication instruction is corresponding.Such as, the command property value in protocol communication instruction is 27h, it is known that current
Described command type is privately owned order, or represents publicly-owned order at control bit for " 1 ", represents privately owned life at control bit for " 0 "
Order, then described second determines that module 50 i.e. can determine that, according to the control bit of input, the life that described command message communication instruction is corresponding
Make type.
In the present embodiment, when described second determines that module 50 determines that described command type is privately owned order, described
Processing module 60 is preset second and is obtained privately owned command token mark in look-up table, and the described privately owned command token mark that will obtain
Knowing in the heading adding command message to, the most described sending module 70 will be added with the life of described privately owned command token mark
Make message send to first terminal, in the heading of described command message, extract privately owned order for described first terminal
Token identifications, and generate response message according to the reply data that described privately owned command token mark is corresponding, being added with feedback should
The response message of answer evidence.
Owing to the definition of current SATA protocol has PIO, (Programming Input/Output Model, CPU perform I/O end
Mouthful instruction read-write data data exchange mode), DMA (Direct Memory Access, direct memory access), FPDMA
Transmission means such as (First Party Direct Memory Access, Party A's direct memory access), wherein PIO transmission is relatively
For DMA and FPDMA, efficiency to compare lowly, and the control of FPDMA transmission means is relative complex, is used under privately owned order communication
Meaning is also little, and the transmission means of FPDMA do not supported by some machine, so using more common DMA transfer mode here,
Therefore, in the present embodiment, preferred described sending module 70 DMA transfer mode will be added with described privately owned command token mark
Command message sends to first terminal, and in like manner, first terminal is also to use DMA transfer mode to feed back response message.
Further, in the present embodiment, described Device i.e. first terminal and Host that is second terminal can be self-defined
Scsi command.Such as in SCSI FIS, Command field 0X50 order represents Write Dma order (i.e. Host to Device
Write the order of data), 0x51 order represents Read Dma order (i.e. the reading data command of Device to host), or permissible
In turn (i.e. 0x50 represents that Read Dma, 0x51 represent write Dma), as long as Host and Device appoints the most permissible.
The message communication device that the present embodiment proposes, when receiving command message communication instruction, the second terminal determines elder generation
The command type that described command message communication instruction is corresponding, when described command type is privately owned order, obtains privately owned command commands
Board identifies, and the described privately owned command token obtained mark is added in the heading of command message, is added with institute the most at last
The command message stating privately owned command token mark sends to first terminal, for described first terminal based on being added with described private
There is the described command message that command token identifies, feed back corresponding response message rather than privately owned command token mark is added
Send to first terminal to the data field of packet, it is to avoid first terminal resolves identifier and identifying code within a data area
Time, logical data and the erroneous judgement of privately owned command token bag occur, the present invention improves the accuracy of protocol communication.
It is understood that this programme is equivalent to add in SATA protocol side the new FIS type of SCSI FIS, thus solve
