Embodiment
Following embodiment refer to the attached drawing.As much as possible, identical is used in accompanying drawing and following specification
Reference indicates same or similar element.Although the aspect of the disclosure can be described, modification, change, Yi Jiqi
It is achieved in that possible.For example, replacement, addition or modification can be made to the element shown in accompanying drawing, and can lead to
Cross and be replaced, resequence or add the stage to disclosed method to change approach described herein.Therefore, below
Embodiment be nonrestrictive, and on the contrary, appropriate scope is defined by the following claims.Example can adopt
Take the form of hardware implementation mode or complete software implementation or the implementation of integration software and hardware aspect.Therefore,
What following embodiment was not considered in a limiting sense.
Mixing OT allows to be decided in its sole discretion from complete OT graceful degradations to less complicated/desired concurrent shape by developer
Formula.The strategy allows incrementally to improve as implementation becomes more complicated.These improvement can by user, business or
Technology priority driven.Mixing OT can be realized by the content editing procedures for allowing cooperation to use.
A kind of existing concurrency policies are " lockings/editor/unblock ".The strategy is easily achieved, but causes the concurrent of difference
Property.For example, to be likely to remain in locking too long by a user, and prevent other users, though other users wish with logic that
This independent mode edits the different piece of shared state or document.
Second of concurrency policies is " renewal/editor/submission ".When user works in different zones, the strategy has good
Good concurrency performance, but need to carry out three-dimensional merging in the case where other users are made that any change.If other are used
Quick change is made at family, then the strategy being capable of real-time lock.In real-time lock, user is because always there is incoming change to wait
It is merged and can never submits change.
Finally, even if when the editor of user affects one another, OT concurrency policies also have fine-grained (fine-
Grained) concurrency and good performance, but it is probably difficult to realize.Existing application transform it is particularly difficult, and
And usually require fully achieving for all types of editors.
It is worth noting that, in the different piece of content editing procedures and document in itself, different types of editor may
Need the concurrency of different stage：1) there is the editor of complete OT supports and quick, fine-grained concurrency (for example, creating, deleting
Remove and mobile object；Edit text)；2) be difficult or impossible to determine for OT systems the change made of user but
It is the known editor that change is had occurred that in specific region (for example, the inline object that is defined by third party of editor；Edit OT
The up to the present unknown object of system)；3) document is made thoroughly change but need not to OT systems expose be what or
Editor where (for example, change Color scheme, theme, page-size, template or slide master)；And 4) OT systems are not known
Whether some contents in road are modified and can not distinguish the modified volume of what content by being checked document
Volume.These editors are fully opaque for system.
For pure OT methods, significant obstacle is presented in all editors in addition to the editor of the first kind.Relatively it is difficult to
Many in the editor of the type of processing actually need not be completely concurrent, or is permitted in the editor of more reluctant type
More with being orthogonal (or almost such) on other, more fine-grained editing essence.For operating and its changing by well
Type (1) editor of understanding, mixed method use complete OT.It is desirable with such user mutual as much as possible
's.The mixing OT methods in view of these targets are provided in terms of the disclosure.
Edited for type (2), the opaque expression of change is encapsulated as opaque operation by the aspect of mixing OT methods.Begin
Operation metadata and data can be sent to server by hair client, without in the identical time.Other client kimonos
Business device can rapidly receive metadata, and alternatively locking (lock-out) other users so that they can not make further
Change (for example, utilizing the progress bar on impacted region).Then other users receive data when data are made available by.
Once receive all data, then finally being capable of intactly application operating, and discharge locking.If understand that data never change
(for example, because originating user disconnects in advance) must be can use, then cancels operation (via OT revocation mechanisms) and discharges locking.
In certain aspects, the opaque expression (for example, binary system blob (binary large object)) of change can be created.
In these aspects, this opaque operation can be applied, but regardless of the virtual condition of the impacted part of document.For example, such as
Fruit is opaque to operate the state that have modified the inline object defined by third party, then operation will require that object exists and is in pre-
Phase position, it is not required that the object is in particular state.This allows to carry out two opaque operations to the same section of document,
Opaque to represent come simple and unadorned to change by each other by simply replacing.
Opaque operation is similar to renewal/editor/submission model, because three-dimensional, which merges, always utilizes incoming state
To replace current state.State through replacement is not necessarily lost, but is resumed if desired, and the state through replacement can retain
In revision history.This causes developer from for the complete OT of difficult object implementatio8, and the concurrency through degradation only limits
In the opaque section of document.
In in terms of the disclosure, type (3) can be directed to and (4) edit and use binary synchronous (binary-sync)
Operation.Whole document can be scanned first against change, and any caused operation is sent to server.In this scene
In, it still there may be the uncomprehending change of OT systems.When making incremental improvements to OT implementations, or work as and transform OT
Into during existing application, this is particularly likely to.In order to rightly replicate these opaque changes, the aspect of mixing OT methods will be whole
Document representation regards opaque blob as.Because the blob can not be typically changed by other operations, and because with it is other not
The Merge Scenarios that transparent operation is used together risks the risk for the excessive content (being probably whole document) for replacing user job, institute
Otherwise the change that other existing operations can not represent must only be represented with blob, and it must be service that it, which operates context,
Version known to device and other users.In order to send and be operated using such, the more special method of use, referred to herein as
" binary synchronous " operates.
In aspect, binary synchronous can be handled, either in operation stream or on wing passage.In order to
For the sake of simplicity, it is pending once there was only a binary synchronous.Wish to submit while another binary synchronous is pending
The client of binary synchronous may being serviced device refusal.On the contrary, its opaque blob can be added to by such client
Revision history is as the state through replacement.Client can not submit binary synchronous, unless the client proves its change is
The binary synchronous completed based on server most recent.
When receiving the request for submitting binary synchronous, server conditionally receives binary synchronous first, at it
The other binary synchronous of locking are attempted when receiving from the data for submitting client.As optimization, server can be opened alternatively
Begin to stream to data into the other clients for it is expected to receive binary synchronous.If server fails that data (example is correctly received
Such as, due to network failure), then server stops binary synchronous and discharges the locking attempted other binary synchronous.Once
Server has all data, and the server just completes binary synchronous, and signals other clients and carry out again
It is synchronous.
Other clients can be by obtaining opaque blob to carry out re-synchronization from server first.Due to transmitting not
Time required for transparent blob, other operations may be applied to the document status of client.Receive client according to
Opaque blob initializes to the backstage copy of document status, and is applied to newer operation.Because using these behaviour
Work may take various time quantums, and client repeatedly checks the operation without application, and is applied to backstage document, until
The backstage document is in server finally known state.
Now, opaque change is only difference is between backstage copy and the active copy being edited by
And any change that user makes recently but not yet being serviced device receives.Client is received now by the operation of user's most recent
Backstage document is copied to from active document.Finally, be only difference is between active document and backstage document be intended to by
Change send or replace, hiding, opaque, receives client exchange active document and backstage document.In the process knot
At beam, all users are editing the documentation release wherein changed and otherwise hidden to OT systems.
Fig. 1 is the block diagram for the system for collaborative editing for showing the aspect according to the disclosure.As shown in figure 1, system 100
Including the first user calculating equipment 102 that can be operated by the first user U1, and server computing device 104.User calculates
Equipment 102 and server computing device 104 are communicated by network.User calculating equipment 102 includes content editor 106.
In the example depicted in fig. 1, content file 110a can be sent to the first user calculating equipment from server computing device 104
102。
System 100 can also include the second user computing device 108 for being connected to server computing device 104, and it can
Operated by second user U2.Second user computing device 108 and server computing device 104 are communicated by network.Second
User calculating equipment 108 includes content editor 110.In the example depicted in fig. 1, can be by content file 110b from server
Computing device 104 is sent to second user computing device 102.
It should be appreciated that both the first user U1 and second user U2 can edit identical document using content editor
Separation version.In this case, the first user U1 is editing documentation release 110a, and second user U2 edits text
Shelves version 110b.Documentation release 110a and 110b are the versions of identical document.User just edits document in Collaborative environment, wherein
The change made by two users should all be updated to the key plate sheet of document.
System 100 represents to be cooperated with shared state with the user of client software (for example, content editor) interaction
Interactive general topology, wherein the change to state travels to via central server (for example, server 104) and utilizes other visitors
The other users (can be any amount of further user) of family end software, but many other methods are (for example, end-to-end friendship
It is mutually) possible.In certain aspects, content editor (for example, content editor 106 and 110) is with cooperation operable
The application run in the user calculating equipment of ground content of edit file.In addition, in certain aspects, content editor and server
Computing device 104 interacts.In some instances, content editor can be it is operable with based on by remote computing device (for example,
Server computing device 104) or the content of another computing device supply generate the browser application of collaborative editing.According to showing
Example, extension are mounted the plug-in unit or adapter for being used as browser application (that is, content editor 106) on the user computing device,
Or it is embedded in browser application.
In this example, content editor is collaborative document editing machine (for example, the Microsoft from Redmond, Washington is public
The WORD document editors of department), or spreadsheet editors are (for example, also from MicrosoftElectronics
Table edit device).It is public that similar non-limiting example content editor can include the Microsoft from Redmond, Washington
DepartmentPresentation Graphics program.
Fig. 2 is for will change the detailed frame of an example of the system 200 that another document is traveled to from a document
Figure.System 200 can be included with multiple client (for example, mobile client 210, the first client 215 and the second client
220) server 205 that end communicates.Server 205 can safeguard basic file, for example, exemplary basis PowerPoint files
225.Basic PowerPoint files 225 can be such file：Mobile client 210, the first client 215, Yi Ji
Each in two clients 220 is being cooperated and is providing editor to server 205 thereon.The attended operation of server 205
History 230.Operation history 230 can include sending each behaviour for basic PowerPoint files 225 and server 205
Make the record changed.Server 205 can also safeguard the list of the note 2 35 for basic PowerPoint files 225.
In exemplary operations in system 200, mobile client 210 can provide to basic PowerPoint files 225
Text editing.In in terms of the disclosure, such text editing can be supported using complete OT to handle.Client 220 can
With for the use of the opaque mixing OT methods for representing to be provided as opaque operation of change are encapsulated to basis
PowerPoint files 225 provide change, and the change is delivered to server 205.Client 215 can be to basic PowerPoint
File 225, which provides, includes that the change of the two can be changed via the opaque operation of binary synchronous transmission and image.
User calculating equipment 102, server computing device 104, server 205, mobile client 210, the first client
215 and second client 220 be illustrating for a large amount of computing systems, including but not limited to desk side computer system, wired
With wireless computing system, mobile computing system (for example, mobile phone, net book, flat or template computer, notebook meter
Calculation machine and laptop computer), handheld device, multicomputer system, based on microprocessor or programmable consumer electronics
Product, microcomputer and mainframe computer.
In addition, aspects described herein and function can be grasped in distributed system (for example, computing system based on cloud)
Make, wherein application function, memory, data storage and search and various processing functions pass through distributed computing network (example
Such as, internet or Intranet) it is operating remotely to each other.According on one side, via airborne computing device display or via with
One or more computing devices associated remote display units shows various types of user interfaces and information.It is for example, each
The user interface and information of type are shown on wall surface and interaction, and various types of user interfaces and information projection arrive
On wall surface.With for put into practice aspect a large amount of computing systems carry out interact including：Thump input, touch-screen input, language
Sound or other audio inputs, gesture input (wherein associated computing device equipped with for capture and explain user gesture with
For detection (for example, camera) function for the function of controlling computing device) etc..
Fig. 3 shows the aspect that multiple operations are applied according to the aspect of the disclosure.Basic file (version 1) can include text
This phrase " foo ".User A and user's B both can be with the collaborative editing basic files.User A can be attempted in basic file
Text " bar " is inserted at index position 3.Similarly, user B can attempt to insert text " quux " at index position 3.By with
The editor that family A is carried out can cause documentation release 2 to include text " foobar ".The editor carried out by user B can cause document
Version 3 includes text " fooquux ".Therefore, OT systems need to use documentation release comprising conversion, are rightly included with creating
The documentation release 4 of text editing twice.Documentation release 4 should include final text results " foobarquux ".In some respects
In, as a result can also be " fooquuxbar ", " foo " or simply null character string.Each result in these results is still
Uniformity property can so be met.The draughtsman of conversion can determine which result is desired.
Application set forth α '=IT (α, β) comprising conversion (IT).This is the first user action α and second user action β
Comprising conversion.In other words, α ' is with having the operation of same effect to the document application α for having applied β.This is followed unanimously
Property property, it is stated that：If α '=IT (α, β) and β '=I Τ (β, α), then alpha+beta '=β+α '.
Fig. 4 shows the application of transition period convergence property.Each change operation can impliedly with the operation application
In document status be associated.IT can produce the new operation with same effect, but new operation can from it is different
Document status is associated.In other words, β '2=β '1+α=Ι Τ (β1, α1), to cause new context to include α effect, and make
It is identical to obtain the context of user action in IT.Wherein, subscript here has explicitly indicated that (operation is applied to context
Document status).Document context is omitted from other equatioies in order to mark, and can be pushed off.
The change that cooperation is substantially simultaneously simultaneously propagated user and made to the document of another user using being related to, and instead
It is as the same.If you can reduce the size of the cooperation message sent by network, cooperation use can be particularly suited for real-time
Carry out.Merge with sending whole document and then performing three-dimensional on the client on the contrary, sending individually change operation (at this
Position insertion character, insertion lantern slide, mobile shape etc.) can be favourable.
Individually change operation can be sent by network, to apply them to the document of other users in opposite side.
Then may no longer be position 3 in opposite side, this is due to another if necessary to insert character in ad-hoc location (for example, position 3)
User keys in some contents before change operates, and causes to be inserted in and carried out at position 12.In another example, a use
Family can attempt to enter shape edlin, and the shape is deleted in the document of other users.Operation conversion is used to turn
These operations are changed, to cause these operations to be properly applied to the document of long-distance user.
In aspect, in each document for operating and being intended to apply to, the operation can have implicit context.Conversion will
The logical file that the operation is applied to is changed to other documents of user from source document.How to write conversion is probably difficult ask
Topic, because each operation allows for being changed for each other operations in pairs.Accordingly, it may be desirable to substantial amounts of front end
Effort, to ensure all presence in these conversions and correctly run and meet all properties or document.
The aspect of the disclosure does not realize complete OT systems, and obtains OT benefit.This can be by being defined to change
To cause some operations (for example, text based change operation) that there is very high performance to realize for a user.
Then more difficult change operation can be handled using lower-performance system.The aspect of the disclosure can create
The batch object to be sent by network, this represents more complicated change operation.Although the benefit of small network packet can
It can lose, but changing operation can exclude from transition matrix and be sent as opaque object.In other words, mixing OT will
Abundant object mixes with conversion and opaque object.In order to avoid the conflict between the change of two users, can use real
Shi Genggai exist notice come alert two users they will being at war with property editor.Alternately, when user tends to be different
The fact that edit these objects can be used for avoiding conflicting.
If user makes specified modification, document is not influenceed on this change remainder be it is uncertain, then
Mixing OT aspect uses binary synchronous.For example, change document subject matter can cause to influence many objects in whole document
Thorough change.It is determined that each change of generation can be proved to be poor efficiency in a document.Therefore, can be only for
Change with associated change operation operates to generate OT.The change behaviour that other more complicated changes can not be associated
Make.The other part of change can be sightless for OT systems.
The change of these " invisible " can be sent to by server with slower rhythm.In certain aspects, can be first
First preserve document.It is then possible to whole document is sent to by another user by network.Because this process spends the time, institute
The dependence for the fact be present：The change included in the document is sightless for OT systems.Simultaneously, it is seen that
Change has been a part for OT systems, because previously generating operation for visible change.
When the document reaches opposite side, the document may be upgraded to the version beyond the document comprising invisible change
This.For example, change document may generate in version 25, once but at change document arrival other users, the user may
It has been upgraded to version 60.This may cause tens in the current document of user to operate not in incoming change document
In.Therefore, it is necessary to by being positioned as close to current revision to change document application OT operation change documents.
In order to which operation is applied into document, document can be opened on backstage.Once document reaches the shape residing for active user
State, only content not in the document of backstage in the document of active user be exactly user just done it is whatsoever interior
Hold, particularly not yet create the change of any operation for which.In certain aspects, user can be with the of short duration period
It is blocked so that the change of these most recents is copied into backstage document.Then it can not pay attention in user or user does not note substantially
Switch document in the case of meaning.And in present (otherwise it is sightless for OT systems) these changes all will be for
Second or the 3rd user show.
In some aspects of the disclosure, multiple users can attempt to carry out binary synchronous simultaneously.If for example, first
The first binary synchronous for including theme change is made to server, then the server will be refused to include the of page layout change
The binary synchronous of two users.This collision can be mitigated by rule and status indicator.For example, when the first binary system is same
When step is in transmission, such notice can be shown for each user：Instruction user before the second thorough change is made
It should wait untill completing the first binary synchronous.In alternative aspect, rule can in place with certain rhythm regularly
Send binary synchronous.In addition, include when that can detect that user have changed document and document be present for OT systems
During certain possibility of sightless change, binary synchronous can be triggered.Include being used for global change for example, user uses
The drop-down menu of function may be used as trigger so that binary synchronous can by relatively early triggering rather than later triggering, with
Make when making change and another user see before change between time minimize.
In in terms of the disclosure, the first change flow from user to server is established.In certain aspects, service
Device can represent the every other user being operated to identical document.In certain aspects, the flow can be not related to
The end-to-end process of server.
First user can make change to document.Then these changes can be sent to service via first pass
Device.Then, other users and system are received and must be implemented in document more by what server was made by other users
Change.When these operations pass through each other, they must be changed, or in the case of opaque operation, an operation will be excellent
Prior to another operation.In such a case, it is possible to the OT operations for representing opaque state change are realized, and conversion causes simply
Ground abandons a state or another state.
In the case of opaque object, it is thus necessary to determine that whether user, which has been completed, is made specific change.For example, with
Family can indicate that to the change that special object is carried out be complete to system.The instruction can be clearly referring to based on system convention
Show (for example, preserving documentation release) or the instruction through deduction.The non-limiting example of instruction through deduction can include working as user
When typically carrying out thump with specific frequency and stopping suddenly.Another non-limiting example can be when user is such asEdition Contains software in change lantern slide when.Once make the instruction, system can start by
Change travels to server.
Then the expression of change can be collected.For example, the modified partial sequenceization of document can be arrived disk.It is alternative
Ground, change object, some of which shape (such as picture or video or sound or intelligent artistic character/image) can be determined in shape rank
It will be saved as changing object.
Next, system can determine actually whether be made that change.Using some opaque objects, it is known that with
Family is there and user clicks on everywhere, but may be unaware that and actually whether be made that substantive change.The process
It can be used for preventing from sending unnecessary packet by network.Compare for example, binary system can be made using previous state.
Furthermore it is possible to open generated state, and the various parts of the state generated can be compared with previous state
Compared with.
The operation that these changes can be encapsulated as in OT systems.The operation can be used for state being changed to up to another with working as
The identifier of the position comprising change is together during side.Operation can also include conversion, if for determining to change
Object then be deleted and perform action or for conflict change priority.Operation can also include timestamp and believe
Breath solves to conflict for help., can be based on the preferential of the author of corresponding conflict change in some aspects of the disclosure
Level rank solves to conflict.
Encapsulated operation is sent to by server and other users by network.With encapsulated operation traverses network
And pass through server and potential intermediate node, and other clients (user) are reached, server can perform some conversions.
Then encapsulated operation can be applied at another client., can will be through using client OT control algolithms
The operation conversion of encapsulation is for ready for applied to document.In certain aspects, encapsulated operation may be due in these conversions
In one conversion in lose and be dropped.In another aspect, the position that encapsulated operation is intended to apply to may be
It is deleted, any operation can not be carried out in this case, and encapsulated operation is dropped.However, the position can letter
It is singly mobile, and conversion can be applied to ensure that encapsulated operation is applied to correct position.Furthermore if two users
Change identical object is attempted, then one in change operation can be dropped.
Once encapsulated operation is ready to be applied to correct object's position, then the object can be by unserializing.Change
Yan Zhi, object become real object from its state through serializing.In certain aspects, this may relate to open warp on backstage
The Obj State of serializing, and be copied into the correct position of existing PowerPoint.If object is image, can make
Realize that size and location adjusts with insertion image API.Once realizing change, object can be apparent in the document of user.
If there is another pair as that can delete or replace previous object in the opening position.
, can be simply according at it if another user attempts editor and is modified the same object that operation is replaced
The object is deleted below.In some aspects of the disclosure, user can be warned incoming destructive volume for object to be present
Volume.This can provide a user chance, either preserve the copy of the object or refuse the incoming change and its is modified
Object as new version resend to it is other everyone.
In in terms of the disclosure, it may be determined that need binary synchronous being sent to server.For example, actually user
It can click on to start binary synchronous.Enter for example, being modified to the animation in content editing procedures and can trigger transmission two
System is synchronous, because assume that multiple users while may not enter edlin to animation compared with making text change.
Therefore, if user opens animation pane, instruction can be presented to user several times before the pane is opened may not
The notice of such change is supported in real time.Lockage button can be clicked on instruction user, or user can wait and count next time
The synchronization drawn.In certain aspects, each user opens animation pane, and lockage button can be indicated (for example, (red using color
Color)), until binary synchronous is sent.
Alternately, binary synchronous can be sent based on system timer.There may be between binary synchronous
The predefined minimum time passed through, to avoid too fast sending synchronization.Predefined maximum time interval can also be used,
Binary synchronous will be sent after the predefined maximum time interval, irrespective of whether it is same to receive binary system as needs
The instruction of step.Such time interval can be opened when user opens document and is actually interacted with the document opened
Begin.In addition, if user receives binary synchronous, then before user interacts with document again, time interval may
It will not start again at.
In the case where due to damage user document correctly can not be opened, urgent binary synchronous can be used, its
In client in hot water will be complained to server.Server can be sent out by requiring the client of all connections to the user
Sending, which can allow user directly to open document and attempting, recovers the binary synchronous of its state to be responded.
Fig. 5 illustrate in greater detail in mixing OT systems such as how client control algolithm 500 in terms of realize team
Row.Operation can receive server operation queue 505 as the part for receiving circulation 510 from server.Determining to send
After binary synchronous, control algolithm can more new incoming and the queue of outflow operation.Control algolithm can keep tracking each
What version operation is applied to, and these operate whether need it is to be converted.Once user stops editor's document and queue is complete
Portion empties, and customer documentation will be in synchronous and consistent.In other words, server receive and store the binary synchronous so that its
The operation for reaching correct rank is not limited to the operation that particular clients are seen.The property of binary synchronous state can be known as
Clean.Therefore, serializing is carried out to the state in client ensures that its user without any unidentified generation grasps
After work, the clean of document, the version of server approval can be sent.
Operation can advance to application queue 515 from server operation queue 505.Then operation can be applied to agency
(proxy) 520, agency 520 is a part for polling loop (polling loop) 525.Agency 520 can be using operation as benefit
Fourth function is supplied to application state manager, for example, PowerPoint OM 530.
Next, agency 520 can be using taking (GET) function to be provided to from PowerPoint OM530 to access
Server is for realization to the operation in basic file.Agency 520 can be communicated with previous agent 535.To first former generation
The comparison that difference between reason 535 and agency 520 is carried out helps in notifying that client control algolithm 500 is right about whether existing
The actual change that basic file is made.The process can be used for preventing from sending unnecessary packet by network.For example, can be with
Binary system comparison is carried out using previous state.Furthermore, it is possible to generated state is opened, and the state that will can be generated
Various parts compared with previous state.
If there is the actual change to be sent, then operation is moved to the operation queue 540 do not submitted.The operation do not submitted
Queue 540 can send a part for circulation 545.The operation queue 540 do not submitted, which can wait, to be received comes from pending submission
The submission of block 550 confirms.This provides the superior method for real-time lock, and wherein user can never submit change, because
It is merged always to there is incoming change to wait.When receiving confirmation, binary synchronous can be provided back to server.
As discussed above, when binary synchronous starts, its one kind that may be in both of which, explicit
(explicit) and passively.Under explicit mode, user clicks on button to start binary synchronous, and user then waits for
It is synchronous to pass through.In certain aspects, mode progress object (for example, bar) can be presented to user to prevent user from being done to document
Go out further change and allow outflow queue to be drained.During the time, it is understood that there may be the queue of the operation generated.One
Denier server provides response for pending operation, it is possible to sends any remaining operation.This produces the server for document
Version number.Then, state can be preserved and sent together., can be with locking user when queue is drained in the case of explicit.
Under passive situation, the chance point that outflow queue is drained can be directed to queue is monitored.For example, document is not edited in user
The of short duration period in, queue can be drained.If have passed through the too long of period when waiting chance point, system can be cut
Change to explicit mode.Here, when queue is drained and state is saved, using progress bar come locking user.
Once establish state, it is possible to which state is sent to server., can be with the shape in some aspects of the disclosure
State retains Liang Ge version numbers together.The OT versions that one version number can be saved with state are associated.This can represent to include
The version of the revision of the last receiving of the document.The second edition number can be the identifier of previous binary synchronous.Then can be with
Regard document status as binary synchronous plus the list applied to its operation.The two version numbers can be used for identifying its
Where state stream.Then, server can verify that binary synchronous is based on the most recent known to server
Binary synchronous.In certain aspects, server can be responsible for ensuring in stream once there was only a binary synchronous.
In certain aspects, when sending the message of request binary synchronous, if locking is in place and permits to be allowed,
Then binary synchronous data will start to send.If user is offline within the period, server can provide pre-determining
Period is used to return, and then release locking.In this case, binary synchronous will not pass through, because server
The partial data for binary synchronous can not be received.
After the license for starting binary synchronous is provided, server can also accelerate to transmit.In this case, service
Device can give notice to all other client, and alerting them may have binary synchronous to carry out, it is assumed that upload client
Actually try to complete to upload in end.Here, server can start to stream out binary synchronous, even if the server does not have also
Whole in data.The whole that another client will be prefetched in the binary synchronous data, and then once upload client
Successfully complete, server will just state the version as next binary synchronous version, and the version is broadcast to all
Client.
