It may include following step as shown in figure 4, being the flow diagram of data transmission method for uplink provided in an embodiment of the present invention It is rapid:
S11, data source obtain data packet to be sent.
The data source for obtaining the data packet to be sent from the first process, first process be comprising mostly into Any of server of journey needs the process of synchrodata, such as when server is network game server, then first into Journey can be, but not limited to as faction's playing method process etc..
As shown in connection with fig. 3, process is the first process to server at the middle and upper levels, is had in the business module in upper layer procedures fast According to generation/loading interface and order generation/loading interface.Wherein, snapshot refers to the full dose data of business module at a time, Order refers to the incremental data that business module generates in a certain period of time.Data source can generate interface or order by snapshot Interface is generated to obtain the data in upper layer procedures in business module, for convenience, the embodiment of the present invention obtains employment single The data obtained in business module are referred to as data packet to be sent.
Specifically, it is illustrated so that business module common in network game server is faction's module as an example, faction's mould Block can provide the generation of snapshot and order and be loaded into interface, initial in scene process and faction's playing method process (upper layer procedures) respectively Change subscriber and data source.When network game server starting, the subscriber in scene process can be into faction's playing method process Faction's module (business module) in data source send data synchronization request, data source adjusts after receiving data synchronization request Interface is generated with the snapshot of faction's module to obtain the synchronous faction's data of the needs in faction's module.For example, working as online game When server starting starts to provide game services, can trigger subscriber in the scene process of each playing method to respective upper layer into Data source in journey sends data synchronization request, so that the data source of each upper layer procedures will be first by calling snapshot to generate interface Beginningization data are synchronized to subscriber, and initialization data is loaded into interface by snapshot again and is written in scene process by each subscriber Data buffer storage in.
On the other hand, when having newly-increased data in business module in upper layer procedures, it can be sent to data source and obtain newly-increased number According to instruction, data source can generate interface by order and obtain in newly-increased data namely the present invention after receiving the instruction Data packet to be sent.For example, the data of modification can be generated after faction's playing method process detection is instructed to data modification, i.e., newly-increased number According to then the data source into faction's playing method process sends the instruction for obtaining newly-increased data, and then data source can pass through order It generates interface and obtains data packet (newly-increased data) to be sent, the newly-increased data can be, but not limited to as the ranking list number in faction According to.
According to the sequence of first in, first out, it is slow that the version number for the data packet to be sent that will acquire is put into version number for S12, data source Deposit the tail of the queue of queue.
It specifically can be refering to what is shown in Fig. 5, version number's buffer queue in the present invention be used to store the data to be sent obtained The version number of packet, and version number's buffer queue maintains three transmission windows, including has confirmed that window, pre- transmission window and and wrap Send window, wherein have confirmed that the version number in window is to have sent and the version number of the data packet of the person's of being subscribed acknowledgement；Pre- hair Sending the version number in window is the version number for having sent but not being subscribed the data packet of person's acknowledgement；And wrap the version sent in window Number for may be to have sent but the version number of the data packet of subscribed person's acknowledgement, it is also possible to for etc. data packet to be sent version This number.It when determining that subscriber is in slow consumption status, and wraps to send and just has version number's presence in window, otherwise version number It can only fall into pre- transmission window, therefore the corresponding version number of tail of the queue of version number's buffer queue may drop into pre- transmission window In, it is also possible to it drops into and wraps in transmission window.For example, giving tail of the queue in Fig. 5 respectively falls in the pre- window and simultaneously of sending Packet sends the schematic diagram of window.Certainly, however, it is determined that the subscribed person of the version number gone out in version number's buffer queue receives and processes, Then in advance send window and and wrap send window in without version number, the tail of the queue in the case of this in version number's buffer queue is corresponding Version number, which drops into, to be had confirmed that in window.
Preferably, version number is that data source gets data packet to be sent from hyperplasia at version number is for characterizing every time The state of data packet to be sent.Subscriber receives after data packet can in real time or timing to data source sends acknowledgement data packet It is true can to know that the corresponding data packet of which version number has been subscribed person after the version number of data sources to acknowledgement for version number It receives, which is not subscribed person's acknowledgement.Specifically, after data source obtains data packet to be sent every time, match for the data packet to be sent A version number is set, which is that the last version number of data packet to be sent configuration obtained is adjacent with data source, in full It is 10 according to the version number that source is the last data packet to be sent configuration obtained, then data source is this data to be sent obtained The version number of packet configuration is 11, and so on.Data source carries version number after for data packet configuration version number to be sent Be sent to subscriber in data packet to be sent and according to the method provided by the invention, when subscriber from received in receiving queue and from After managing data packet, acknowledgement instruction can be sent to data source, the version number of the data packet of acknowledgement is carried in acknowledgement instruction, thus After data sources are indicated to acknowledgement, can be indicated according to acknowledgement in the version number that carries determine that the data packet sent is being ordered The processing status of reader side.
Furthermore data source further includes at data other than comprising version number into the data packet to be sent that subscriber sends Reason indicates and required data, such as at the data for including in the corresponding data packet to be sent of a ranking list list in faction Reason be designated as generate ranking list list instruction and corresponding data make a living into ranking list list needed for data, such as each object for appreciation Family identifies and for parameter value needed for measuring ranking；For another example, a faction, corresponding data to be sent are added in a player The data processing for including in packet is designated as that faction's instruction is added and required data are the mark of player to be added and are intended to be added The mark of faction.
S13, data source work as the number determined to fall into and wrap in version number's buffer queue and send the version number in window It is that a packaging data packet is sent to subscriber by the packet combining to be sent of respective numbers when amount reaches packaging threshold value.
Specifically, send in advance window with and wrap that send window adjacent, and it is pre- send window appear in and wrap transmission window it Before, as shown in connection with fig. 5, first there is pre- transmission window, when the quantity for determining version number in pre- transmission window reaches pre- transmission window When the size of mouth, then when data source obtains data packet to be sent from business module again, the version number of the data packet to be sent is fallen Enter and wrap to send in window.For example, if the size for sending window in version number's buffer queue in advance is 50, working as data with reference to Fig. 5 When source determines that the quantity of the version number 11~60 fallen into pre- transmission window reaches 50, that is, show that current subscriber is in unrestrained and disappears Take state, increases in order to avoid synchrodata is delayed, it is after data source subsequent time gets data packet to be sent, this is pending Send the version number 61 of data packet to drop into and wrap send window in, with reference to shown in Fig. 6 a, until and wrap send window in version number Quantity when reaching packaging threshold value, according to the sequence that version number is ascending, by the version number for meeting packaging threshold value it is corresponding to Packet combining is sent into a packaging data packet, the packaging data packet is then sent to subscriber, i.e., by the hair of data source It send the data in queue to send pointer to be directed toward in the corresponding data packet to be sent of version number 61, with reference to shown in Fig. 6 b, wait drop into And when wrapping the quantity of version number sent in window and reaching packaging threshold value, packaging is carried out by method provided by the invention, and will spelling It wraps obtained packaging data packet and is sent to subscriber.Such as when packaging threshold value is 10, sent in window when dropping into and wrapping Version number is 61~70, that is, falls into and the quantity for wrapping version number in transmission window reaches 10, then version number 61~70 is corresponding Then the packaging data packet is sent to subscriber at a packaging data packet by packet combining to be sent, at this time and wrap transmission Version number 61~70 in window can be characterized as having sent but the version number of the data packet of not subscribed person's acknowledgement, and version number 71 the version number of data packet to be sent such as can be characterized as.So, with packaging sending method send packaging data packet to When subscriber, subscriber need to only read a packaging data packet from receiving queue can be by the data of packaging threshold value corresponding number Packet disposably read out, in the prior art do not use packaging data packet, every time from receiving queue only reading one data Packet is compared, and read access time and the occupied resource of multiple read data packet are reduced, can be by the time of these savings and resource Data packet is handled, it is possible thereby to accelerate the speed that subscriber handles data packet.For example, also being carried out so that packaging threshold value is 10 as an example Illustrate, when data source sends the packaging data packet obtained by 10 packet combinings to be sent into the receiving queue of subscriber Afterwards, subscriber can disposably read the packaging data packet from receiving queue, i.e., disposably read 10 data packets, and nothing 10 times, which need to be executed, could read 10 data packets, and therefore deducing that reduces 9 read data packets occupied time and money Source improves the speed that subscriber handles data packet so that time and resource that subscriber is saved using these handle data packet, So that subscriber comparatively fast terminates unrestrained consumption status.
In addition, when reaching packaging threshold value, data source using and will meet by the way of wrapping packaging threshold value version number it is corresponding Data packet to be sent be combined into a packet and sent, subscriber can be allowed once to receive batch of data packet and uniformly locate Reason, the data of subscriber can be increased considerably by sending packaging data packet really by packaging mode by test discovery data source Packet consuming capacity, in the case where process CPU usage reaches 80% where subscriber, data source is with 10 data packets to be sent It is merged into a packaging data packet to send, be sent relative to not packaging, the consumption rate of subscriber is increased to 5 times or so, specifically It can be with reference to shown in Fig. 6 c.It can be concluded that, packaging data packet is sent to by subscriber using packaging sending method from Fig. 6 c, so that Subscriber has more time and resource processing data packet, to accelerate data processing speed, terminates unrestrained consumption processing shape ahead of time State, while the delay that synchronization process generates is reduced using packaging sending method.
Preferably, the packaging threshold value can be adjusted according to the consumption processing status of subscriber.
Preferably, data source is after getting data packet to be sent, however, it is determined that drop into the version in pre- transmission window out Number amount is no more than the pre- size for sending window, that is, indicates that the pre- window that sends is discontented, then by data packet to be sent in the present invention The tail of the queue that version number is put into version number's buffer queue can be understood as the version number of the data packet to be sent dropping into pre- transmission Close to the version number of upper one data packet to be sent in window, while the data packet to be sent is transmitted directly to subscriber.For example, The version number of the data packet to be sent currently got is 57, and when determining that pre- transmission window is less than, then by the number to be sent The tail of the queue in pre- transmission window is dropped into according to the version number of packet, i.e., is filled into version number 57 in pre- transmission window and version number 56 At adjacent position, needle locating is sent to version number with reference to shown in Fig. 7 a, while by the data in the transmit queue of data source 57 corresponding data packets to be sent, and the data packet to be sent is transmitted directly to subscriber, with reference to shown in Fig. 7 b.
Specifically, data source is by packaging data when sending packaging data packet or data packet to be sent to subscriber Packet or data packet to be sent are sent in the receiving queue of subscriber.When data source sends packaging data packet to subscriber, spell Quantity information is carried in the packet header of bag data packet, which is used to indicate the number for the data packet that packaging data packet includes Amount.Wherein when obtaining packaging data packet, data source carries out packaging according to the agreement appointed with subscriber, and such subscriber exists After reading packaging data packet, processing of unpacking is carried out to packaging data packet according to scheduled agreement, and correctly read each data packet. Then subscriber correctly reads out required data further according to the format arranged with data source from data packet.
It should be noted that it is slow that data source can distinguish maintenance release number for each subscriber when subscriber's more than one Queue is deposited, the service identification and version number's buffer queue of subscriber can be set for executing different business in each subscriber Corresponding relationship, with distinguish data source be each subscriber maintenance version number's buffer queue, further according to each version number cache Quantity of the version number in each window selects the mode that data packet is sent to respective subscriber in queue.
S14, subscriber obtain the packaging data packet of data source transmission from receiving queue.
Subscriber's consumption data can be divided to two processes, and one is to receive data, i.e., data packet is obtained from receiving queue； The other is processing data, i.e. execution data modification logic.
When executing this step, have in scene process special module be responsible for notifying to have in subscriber's receiving queue it is newly-increased Data packet, thus subscriber can read the data packet of data source transmission from receiving queue, however subscriber also needs to handle The data packet read before handles the fast speed of data packet if current subscriber's cpu load is smaller, in receiving queue Increase a data packet newly, subscriber can read the newly-increased data packet and then be handled from receiving queue；If current subscription When person's cpu load is larger, after subscriber receives the notice of newly-increased data packet, may currently in process other packets or it mention For other services, at this moment subscriber can not obtain newly-increased data packet from receiving queue, handle current data to subscriber When the service load after packet or currently provided is less high, data are successively read from receiving queue further according to first in, first out principle Packet will lead to subscriber and send data packet in this case if subscriber does not use packaging mode to send data packet always Speed be significantly larger than the speed that subscriber handles data packet, cause subscriber to be in slow consumption processing status, if data source exists When determining that subscriber is in slow consumption status, packaging data packet is sent by the way of packaging, then subscription can be effectively relieved The slow consumption processing status of person, and quickening subscriber terminates the speed of slow consumption status.
The quantity information that S15, subscriber are carried in the packet header according to packaging data packet splits into the packaging data packet The data packet of respective numbers.
In this step, after subscriber reads packaging data packet from receiving queue, then need according to packaging data packet Packet header in the quantity information that carries, the packaging data packet is split into the data packet of respective numbers, such as when quantity information is When 10, then the packaging data packet is split into 10 data packets.
Where data packet after fractionation is written to subscriber by S16, subscriber in the data buffer storage of process.
The data packet received for being written in the data buffer storage of the second process by the subscriber, second process It can be to be in same clothes with the first process comprising the process for needing to rely on the data in other processes in multi-process server It is engaged in device, when the server is network game server, and the first process is faction's playing method process, then the second process can be The scene process of faction's playing method service is provided.
In this step, subscriber is according to the data processing instruction and required data execution in each data packet after fractionation After respective handling, the data for needing to be loaded into data buffer storage in scene process are loaded by snapshot shown in calling figure 3/order Interface is loaded into data buffer storage, and the scene process in Fig. 3 is the second process.If data are the number for initializing scene process According to then by calling snapshot loading interface that the data for initializing scene process are loaded into data buffer storage, if in data packet Data make a living into the relevant data of ranking list, then these data are on the one hand loaded into data by call instruction loading interface and delayed In depositing, ranking list list on the other hand is generated using these data and shows player.
If what subscriber read from receiving queue is single data packet, directly according to the data processing in the data packet Instruction and required data execute corresponding operation, can specifically refer to the above-mentioned treatment process to multiple data packets.
S17, subscriber send the instruction of data packet acknowledgement to data source.
In this step, when subscriber from receiving queue read data packet and after handle it, then can be to data source Send acknowledgement instruction.Specifically, subscriber then can send the data packet really to subscriber immediately with one data packet of every processing Instruction is received, the version number of the data packet is carried in acknowledgement instruction；On the other hand, subscriber can also handle multiple data packets Afterwards, then by the instruction of the acknowledgements of these data packets disposably be sent to data source, i.e., carried in the acknowledgement indicates it is multiple Handle the version number of data packet.
When S18, data source receive the data packet acknowledgement instruction of subscriber every time, sent described in synchronous slide in advance window and And transmission window is wrapped, so that removing the pre- transmission window by the version number of the data packet of acknowledgement.
In this step, when data sources to acknowledgement instruction carry be the version number of a data packet when, then slide It is pre- send window and and wrap transmission window, by the version number carried in acknowledgement instruction from pre- the transmissions window removal.Example Such as, the version number carried in the acknowledgement instruction being currently received is 11, then sends window in version number's buffer queue in advance and and wrap Schematic diagram before and after transmission window sliding can be with reference to shown in Fig. 8 a.Pre- transmission window is slided in Fig. 8 a and and wraps transmission window Afterwards, version number 11, which drops into, has confirmed that in window, and version number 61 drops into pre- transmission window.
When carrying multiple version numbers in acknowledgement instruction, then by sliding the pre- transmission window and and wrapping transmission window Mouthful, multiple version numbers are removed from pre- the transmissions window, if while and wrap transmission window Zhong You version number, phase will be no more than Answer the version number of quantity from and wrap to send in window and remove and be added into pre- transmissions window, such as acknowledgement indicate in have N number of version This number, then this N number of version number can be removed from the pre- transmission window, however, it is determined that go out it is described and wrap send in window have it is super GuoNGe version number, then since and wrap send version number adjacent with pre- transmission window in window QuNGe version number be added into it is pre- Send window in, and if wrap send window in version number's quantity be less than it is N number of, will and wrap send window in all versions number fill into It is sent in window to pre-.Such as 5 version numbers are carried in acknowledgement instruction, it is 11~15, then can slides pre- transmission window and simultaneously Packet sends window, this 5 version numbers are removed from pre- the transmissions window, and if wrap transmission window Zhong You version number, will simultaneously Packet sends not more than 5 version numbers in window and is added into pre- transmission window, specifically can be with reference to shown in Fig. 8 b, due in Fig. 8 b And wrapping the version number's quantity sent in window is more than 5, then sliding it is pre- send window and and when wrapping transmission window, can be by 61 ~65 this 5 version numbers fill into pre- transmission window.If quantity that is certain and wrapping version number in transmission window is not more than 5, Incite somebody to action and wrap send window in all versions number be added into pre- transmission window.
Specifically, send version number's instruction in window in advance is that its corresponding data packet has been sent but not subscribed person connects It receives.Therefore the data packet processing status of subscriber side can be known by sending the quantity of version number in window in advance, and send out in advance The sensitivity for sending the size of window to determine slow consumption detection.When the pre- size for sending window is 0, show that data source uses always Packaging sending method sends packaging data packet to subscriber；And when sending when being dimensioned to infinity of window in advance, show to count Send data packet to be sent in real time according to source.Therefore, the setting for sending the size of window in advance directly affects subscriber and consumes shape slowly The testing result of state.Fig. 9 a gives subscriber when data packet to be sent is written with fixed writing speed in data source and loads variation Shi Butong sends the variation schematic diagram of subscriber's consuming capacity under window in advance, and the pre- size for sending window is illustrated in Fig. 9 a and is The change of subscriber's CPU usage and subscriber's consuming capacity under 0,0.1* writing speed, 0.2* writing speed and 10* writing speed Change schematic diagram, it can be seen that the pre- size for sending window is that 0 corresponding consuming capacity curve is above other pre- transmission windows pair The consuming capacity curve answered, that is to say, that the pre- window that sends is smaller, shows more early unlatching packaging sending method, the consumption of subscriber Ability is also higher.
But using packaging sending method send packaging data packet when, source side only and wrap send window in version number Quantity when reaching packaging threshold value, just can from and wrap to send in window and started to query from the version number of initial position, until inquiry 1 corresponding version number is subtracted to packaging threshold value, by the corresponding packet combining to be sent of the version number between this at a packaging Data packet, then packaging data packet is sent to subscriber, can so exist and send delay, Fig. 9 b gives data source with solid It is different when subscriber loads variation when data packet to be sent is written in fixed writing speed to send bring delay signal under window in advance Figure, it can be seen that when corresponding CPU usage in the region where subscriber's CPU usage is less than label 1, i.e. subscriber Loading the relatively low consumption delay in when not using packaging sending method to send data packet to be sent when normally consuming is most Small, that is to say, that it is pending using being sent under the corresponding pre- transmission window of 10 times of writing speeds in Fig. 9 b when cpu load is lower The delay of data packet is sent to be less than packaging sending method bring delay when the pre- size for sending window is 0, this is because no matter Which kind of consuming capacity subscriber, which handles, which is all made of packaging sending method, to give birth to additional and biggish delay because waiting and contracting for fixed output quotas.When ordering Reader's load is larger to cause CPU usage higher position to use packaging sending method to send packaging data packet again when slow consumption, can To find that the pre- delay for sending the smaller generation of window is smaller, i.e. CPU usage is greater than corresponding in the region at 1 place of label in Fig. 9 b CPU usage when, it is 10 that bring consumption delay is less than the pre- size for sending window instead when the pre- size for sending window is 0 The delay of times writing speed bring.To sum up, in conjunction with Fig. 9 a and 9b it can be concluded that, when subscriber is in normal consumption status, lead to Delay can be reduced by crossing the certain pre- transmission window of setting and sending data packet to be sent in real time, be adopted when subscriber, which is in, to consume slowly Packaging data packet is sent with packaging sending method, can not only reduce delay in this way but also accelerates the ability of subscriber's consumption.
It specifically, is to handle a data packet or place since subscriber is when sending acknowledgement instruction to data source It has managed and has just sent after multiple data packets, can so have acknowledgement delay, in order to avoid the delay of acknowledgement bring causes to count Do sth. in advance the generation for this case that packaging sending method is used to send packaging data packet according to source, the present invention is to the pre- size for sending window It is configured, pre- transmission window is dimensioned to public affairs by comprehensive subscription person consuming capacity and transmission two aspect factors of delay Shown in formula (1):
Y=max (0.1*WPS, (RTT+tdelay) * WPS) (1)
Wherein, y indicates the pre- size for sending window；
WPS indicates the speed of write-in data packet to be sent per second；
RTT indicates round trip delay time；
tdelayIt indicates that subscriber's single is sent at least two data packets prolong caused by processed acknowledgement instruction When.
In formula (1), after RTT expression normally sends data packet to be sent to subscriber, and subscriber receives data packet The delay that acknowledgement instruction generates is sent, will normally send the delay and subscriber's single that data packet to be sent generates in formula (1) It sends to be delayed caused by the acknowledgement instruction for handling at least two data packets and take into account, can refer to avoid because sending acknowledgement Show that bring delay causes data source that packaging sending method is used to send packaging data packet to subscriber ahead of time.
When sending acknowledgement instruction immediately after subscriber often receives a data packet and handles it, comprehensive subscription Two aspect factors of person's consuming capacity and delay, the size of the pre- transmission window of configuration are shown in formula (2):
Y=max (0.1*WPS, RTT*WPS) (2)
Wherein, y indicates the pre- size for sending window；
WPS indicates the speed of write-in data packet to be sent per second；
RTT indicates round trip delay time.
It can be generated since data source sends data packet to be sent between subscriber and subscriber's return acknowledgement instruction RTT delay, in order to guarantee that data source can receive first version number pair in pre- transmission window when sending window in advance and being filled The acknowledgement for the data packet to be sent answered indicates, pre- transmission window can be allowed normally to slide, so that it is too early also to avoid data source It is sent using packaging sending method and occurs sending delay caused by packaging data packet.
Preferably, when subscriber is in slow consumption status for a long time, if data source continues with packaging sending method to ordering Reader sends packaging data packet, and the slow consumption status of subscriber is also unable to get releasing, therefore the present invention is in order to avoid this asks The generation of topic, to and wrap send window size limit, when fall into and wrap send window in version number's quantity be more than simultaneously When packet sends the size of window, then the version number of the subsequent data packet to be sent got is dropped into non-transmittable window, With specific reference to shown in Figure 10, version number shown in Figure 10 is an example, is not to say that the pre- size for sending window is exactly 50 and wrap that send window size be exactly 950 etc., the pre- size for sending window can be according in the acknowledgement instruction that subscriber returns The quantity of the version number of carrying determines, and and wrap and send the size of window and can be, but not limited to as 5*WPS.Similarly, work as number After the acknowledgement instruction for receiving subscriber's transmission according to source, according to acknowledgement indicate in the version number that carries, slide the pre- window, simultaneously of sending Packet sends window and non-transmittable window so that the version number in acknowledgement instruction removes from pre- send in window, and incite somebody to action and wrap hair It send the version number of respective numbers in window to be added into pre- transmission window, the version number of respective numbers in non-transmittable window is fallen into To and wrap transmission window, however, it is determined that be added into out it is pre- transmission window in the corresponding data packet to be sent of version number it is not sent then will These data packets to be sent are transmitted directly to subscriber, while if it is determined that being added into and wrapping and send version number in window and simultaneously Packet sends the quantity of remaining version number in window and reaches packaging threshold value, then according to and wrap and send the sequence of window from left to right, Successively data packet to be sent corresponding to the version number for meeting packaging threshold value merges processing and obtains packaging data packet and send To subscriber.
It should be noted that the version number that subscriber when sending acknowledgement instruction to data source, carries in acknowledgement instruction Amount be it is variable, as single sends the acknowledgement sent to the acknowledgement instruction of 10 data packets or bill time to 15 data packets Instruction, that is to say, that the version number's quantity carried in the acknowledgement instruction of transmission can change according to the actual situation.But for spelling Bag data packet, when sending acknowledgement instruction, the version number in packaging data packet needs to carry in an acknowledgement instruction, such as on 10 version numbers are carried in the acknowledgement instruction of secondary transmission, current subscriber obtains packaging data packet, and packaging data packet is by 15 What a packet combining obtained, then subscriber could incite somebody to action only after handling all data packets in packaging data packet The version number of this 15 data packets, which carries, is sent to data source in acknowledgement instruction.
Preferably, the average transmission speed that can also send data packet to be sent using data source replaces writing speed come really Determine the pre- size for sending window and and wraps the size for sending window.
In addition, the data transmission method for uplink provided according to the present invention, Figure 11 a and 11b give subscriber and are in normal consumption State and data in slow consumption status send schematic diagram.In Figure 11 a and 11b by send in advance window size be 50 for into Row explanation, pre- send includes two parts content in window, that is, has been sent transmittable with residue, wherein sent for characterizing The version number of the data packet sent to subscriber, residue can be transmitted for characterizing the version that can also be fallen into pre- transmission window Number.In Figure 11 a data source by version number be 1~11 data packet be sent to subscriber, at this time in advance send window in version number 1~ 11 is have sent, and 12~50 be remaining transmittable；After receiving the acknowledgement instruction of subscriber's transmission, indicated according to the acknowledgement The version number 1~10 of middle carrying, the sliding of trigger data source has confirmed that window and pre- transmission window, so that version number 1~10 falls into Version number 11 is to have sent in pre- transmission window to having confirmed that in window, and after sliding, and 12~60 be remaining transmittable；It is subsequent Data source can drop into the version number of data packet to be sent in pre- transmission window when getting data packet to be sent, and The data packet to be sent is sent to subscriber, that is to say, that drop into the corresponding number to be sent of version number in pre- transmission window It can be transmitted directly to subscriber according to packet, subscriber can continue to confirm in batches, that is, send really after receiving data packet Receive the acknowledgement carried in instruction to the corresponding data packet of version number 11~20.
The corresponding data packet to be sent of version number 1~12 is sent to subscriber, and version number 1 by data source in Figure 11 b ~10 subscribed person's acknowledgements, then version number 1~10, which drops into, has confirmed that in window, and version number 11~12 drops into pre- transmission window In mouthful and to have sent, 13~60 be remaining transmittable in pre- transmission window.When data source by version number 13~60 it is corresponding to It sends after data packet is sent to subscriber, pre- to send in window 11~60 be to have sent, and residue can be transmitted as sky, then shows pre- It sends window to be filled, when subscriber causes load higher due to the influence of other playing methods at this time, not in time from receiving queue Middle acquisition data packet simultaneously sends acknowledgement instruction to data source, in this way when data source determines that pre- transmission window is filled, thus You can learn that subscriber is in slow consumption status, then when data source is subsequent gets data packet to be sent, by data to be sent The version number 61 of packet drops into and wraps and sends in window, and the data packet to be sent cannot be sent to subscriber in real time at this time, need The version number for dropping into and wrapping and send in window is waited to reach packaging threshold value.If not receiving the acknowledgement of subscriber's transmission also at this time Instruction, then each fall within later release number 62 etc. and wrap in transmission window, sends version number in window when counting and wrapping Amount reaches packaging threshold value, and when such as packaging threshold value being 10, then data source is by the corresponding packet combining to be sent of version number 61~70 Subscriber is sent at a packaging data packet, then by the packaging data packet.When the load of subscriber gradually decreases, start from Data packet is obtained in receiving queue, and sends acknowledgement instruction to data source, and sliding sends window in advance after data source receives acknowledgement instruction Mouthful and and wrap transmission window, if send in advance in window it is remaining it is transmittable be not sky, it is determined that subscriber is no longer on slow consumption shape State, it is subsequent get data packet to be sent after, while the version number of data packet to be sent being dropped into pre- transmission window, The data packet to be sent is transmitted directly to subscriber.
S19, data source slide pre- the transmissions window and and after wrapping transmission window, when having the version number of data packet from institute It states and wraps and send window when being added into pre- the transmissions window, however, it is determined that fill into the corresponding data of version number of pre- transmission window out Wrap it is not sent, then will fill into it is pre- send window the corresponding data packet to be sent of version number be sent to subscriber.
In this step, slide pre- the transmissions window and and wrap and send in window, due in transmission window pre- before sliding Version number is used to indicate the corresponding data packet of its interior version number and has sent but non-acknowledgement, and and wrap the version number sent in window When only reaching packaging threshold value, just the corresponding packet combining of these version numbers can be sent to subscription at a packaging data packet Person, this, which has also indicated that and has wrapped, sends in window that may send may also be not sent for the corresponding data packet of version number.Therefore exist By and wrap send window in version number be added into pre- transmission window after, it is thus necessary to determine that be added into version number in pre- transmission window Whether corresponding data packet is sent to subscriber, if not sent to subscriber, successively by the corresponding data packet of these version numbers It is sent to subscriber.
Preferably, Figure 12 a and 12b give after using data transmission method for uplink provided by the invention, at the data of subscriber Manage effect diagram, it can be seen that when process load is lower where subscriber, in Figure 12 a and packet rate is 1 characterize data packet Version number each falls in pre- transmission window, does not fall within and wraps in transmission window.When loading increase with process where subscriber, It sends and packet rate is also increasing, show that subscriber is in slow consumption status, data source is sent out using packaging sending method to subscriber Send packaging data packet.Delay contrast schematic diagram shown in Figure 12 b can be seen that over time, where subscriber into When journey load variation, caused consumption is not prolonged when packaging sending method is used and sent by the way of data packet to be sent in real time Fluctuation is very violent late, and sends the mode of data packet according to process load variation adjustment where subscriber (subscriber's load is low When data source send in real time, subscriber load it is high when data source use packaging sending method) generate afterwards consumption delay on the whole It is that comparison is stable, and relatively low, therefore data packet sending method is accordingly adjusted not only according to the data processing state of subscriber Subscriber can be accelerated to terminate slow consumption status, delay can also be reduced to a certain extent.
Data transmission method for uplink provided by the invention, data source is after getting data packet to be sent according to the suitable of first in, first out Sequence, the version number for the data packet to be sent that will acquire are put into the tail of the queue of version number's buffer queue, are determining that the version number is slow When depositing the quantity of version number for falling into and wrapping in queue and send in window and reaching packaging threshold value, by the data to be sent of respective numbers Packet is merged into a packaging data packet, is then sent to subscriber, compared with sending data packet to be sent to subscriber one by one, orders Reader can once read multiple data packets from receiving queue, to reduce the time of read data packet and save reading Take the occupied resource of data packet；In addition, subscriber when receiving packaging data packet, takes according in the packet header of packaging data packet The packaging data packet is split into the data packet of respective numbers by the quantity information of band；And the data packet after fractionation is written to In the data buffer storage of process where subscriber, handles data packet since subscriber has more resource and business service is provided, To accelerating the processing speed of data packet, and then the delay that while also just reducing synchrodata generates, especially in subscriber institute When process load in place's is higher, using method provided by the invention, subscriber can be prevented to be in slow consumption status for a long time.
Based on the same inventive concept, a kind of data sending device is additionally provided in the embodiment of the present invention, due to above-mentioned apparatus The principle solved the problems, such as is similar to data transmission, therefore the implementation of above-mentioned apparatus may refer to the implementation of method, repeats place not It repeats again.
It as shown in figure 13, is the structural schematic diagram of the data sending device of source side provided in an embodiment of the present invention, packet It includes:
