Technical scheme is described in further detail below by drawings and the specific embodiments.
Embodiment one
The invention provides it is a kind of transmit data method, applied to barrage it is live in, methods described includes：
S101, from interactive direct broadcasting room is loaded onto between current live, living broadcast interactive data are gathered in the interactive direct broadcasting room
Bag；
In this step, when wanting to carry out interactive with main broadcaster between current live because of user, it is necessary to carry out even wheat with main broadcaster, use
Family need to main broadcaster send even wheat request, main broadcaster have received this connect wheat request after, main broadcaster and user will then enter same interaction
In direct broadcasting room, the dynamic direct broadcasting room is to connect wheat room.
Specifically, based on the even wheat request, by the loading built-in function for calling Windows operating system
LoadLibrary, using douyuInterActive.dll as the parameter for connecting wheat service module so that wheat service module will be connected
DouyuInterActive is loaded onto in even wheat server.Company's wheat server in the present embodiment can be live companion.
Then the establishment interaction interface Service Instance function that even wheat service module provides is called
CreateInteractiveSdkInstance, to create an interactive even wheat service module interface
IDouyuInterActiveSdk。
Login identification ID and the main broadcaster for finally obtaining user are current just in live live room ID；Based on interaction even wheat clothes
It is engaged in module interface, according to the login identification ID and live room ID by the interactive data of the user and the main broadcaster
Live data is loaded onto in the interactive direct broadcasting room, and living broadcast interactive packet is gathered respectively in the interactive direct broadcasting room.It is described
Living broadcast interactive data include：The interactive data of the interactive data of user, the live data of main broadcaster and main broadcaster, these data can be
Video data and voice data, the living broadcast interactive data include multiple packets.
S102, judge the packet size whether beyond MTU MTU capability value；If the data
The size of bag exceeds the capability value of the MTU, then carries out burst to the packet, form each sheet data bag；
In this step because when being carried out data transmission using udp protocol, the UDP message headers of live data transmission be
In network hierarchy model, UDP is in transport layer, and its lower floor is IP network layer, to data transfer to during IP network layer, it is necessary to judge
The size of packet whether beyond MTU MTU capability value；If the size of the packet is beyond the MTU's
Capability value, then burst is carried out to the packet on the basis of MTU capability value, form each sheet data bag.Wherein, the MTU
Capability value be 576 bytes.
During appearing in each sheet data bag of transmission, because certain reason causes some sheet data bag to be lost
Lose, or in receiving terminal, because receiving the reasons such as buffering area is full, cause each sheet data bag to be dropped in receiving terminal, then will
Cause whole big packet imperfect, so as in the Internet of receiving terminal by the situation of whole data packet discarding, it is described to institute
State packet and carry out burst, after forming each sheet data bag, in addition to：
The integer vernier value sended of current slice packet is obtained, the current slice packet is in each sheet data bag
Any piece of data bag；Judge the integer vernier value sended of the current slice packet and default transmission station location marker
Whether initial value is consistent；If the integer vernier value sended of the current slice packet is initial with default transmission station location marker
Value is consistent, then is starting sheet packet using current sheet data described in the first mark code labeling.
Obtain the integer vernier value sended of the current slice packet and sizes values sizeToSend of current slice packet, institute
Current slice packet is stated as any piece of data in each sheet data bag；If the sended+sizeToSend=
PacketSize, then it is end sheet data bag using current slice packet described in the second mark code labeling；Wherein, it is described
PacketSize is the sizes values of the current slice packet.
In the present embodiment, the default initial value for sending station location marker is 0, and first identification code is the lowest order of byte
Bof, the second identification code are the second bit eof of the byte；That is, when integer vernier value sended is 0, expression is current
Sheet data bag is starting sheet packet, then with regard to bof be 1.
As sended+sizeToSend=packetSize, current slice packet is represented to terminate sheet data bag, then
It is 1 with regard to eof.
If current sheet data is unsatisfactory for above-mentioned two situations, eof and bof are 1, and it is middle to represent current sheet data
Sheet data bag.In general, when the sizes values of packet are less than MTU capability value, it is 1 feelings that eof and bof, which just occurs,
Condition.
Thus starting sheet packet, intermediate packet and sheet data bag progress clearly differentiation can be terminated.
S103, utilize each sheet data bag described in UDP UDP sequential deliveries；
After forming each sheet data bag, each sheet data bag described in UDP UDP sequential deliveries is utilized.
When here, because being carried out data transmission using udp protocol, it is possible that out of order situation, than the sheet data of transmission
Bag is 1,2,3；And the sheet data bag that receiving terminal receives is probably 1,3,2；So in order to occur it is out of order in the case of, receive
End correctly can be also combined to packet, it is necessary to add index value to each sheet data bag.
Specifically according to the transmission order of each sheet data bag, index value is added to each sheet data bag successively；Institute
Index value is stated according to default incremental spacing from default initial index value to be incremented by.For example initial index value is 0, incremental spacing
For 1 when, then when sending first sheet data bag, the index value of first sheet data bag is just 0；The rope of second sheet data bag
It is 1 to draw value, the like.Receiving terminal is after these sheet data bags are received, can also be according to rope even if there is out of order situation
Draw value each sheet data bag is carried out being correctly ordered combination.
When transmitting current slice packet, whether had time in the data window queue m_udpWindow for judging to pre-establish
Not busy data window, if the idle data window be present, transmit current slice packet, and by the current slice packet
Preserve into the data window of free time.If in the absence of the idle data window, by current slice data pack buffer pending
Send in data queue.The current slice packet is any piece of data bag in each sheet data bag.
In the present embodiment, the data window queue includes multiple data windows, and the idle data window can also
Referred to as currently there are the data window or sliding window of capacity.The capacity of the default data window queue is 255 bytes,
That is the total capacity of the idle data window is 255 bytes.
Further, after current slice packet is transmitted, in addition to：Create timer；The time of the timer can be with
Preset, the time of timer is 1s in the present embodiment；The current slice packet is stored to the data window queue
In；After receiving terminal receives current slice packet, obtain the index value of the current slice packet, and based on the index value to
Transmitting terminal returns to the confirmation of the current slice packet, and the confirmation includes：ACK confirms bag.
Transmitting terminal judges the confirmation of receiving terminal return whether is received in default timing, if receiving institute
Confirmation is stated, then the current slice packet is deleted in the data window queue, and delete the timer.If do not connect
The confirmation is received, in addition to：Continue to transmit the current slice packet, and by the weight of the current slice data packet header
Open position is arranged to retransmit ident value, and the re-transmission ident value could be arranged to 1, and reset the timer.Thus can root
Packet loss phenomenon is avoided the occurrence of according to affirmation mechanism and retransmission mechanism.
So correspondingly, receiving terminal obtains data window team when it is 1 current slice packet to receive re-transmission ident value
Minimum index value in row, judges whether the index value of the current slice packet is more than minimum index value, if being more than, then it represents that
Current data packet is to need packet to be processed；If it is less than, then it represents that the current slice packet is the packet for repeating transmission
(having received before), then directly abandon the current slice packet.
In addition, in order that transmission rate can be controlled by obtaining transmitting terminal, when transmitting terminal receives the confirmation letter of receiving terminal return
After breath, the index value of current slice packet is obtained according to confirmation, based on the index value in the data window queue
The current slice packet is deleted, so that the data window that current slice packet takes is in idle condition, thus may be used
To transmit lower piece of data bag, after transmitting lower piece of data bag, and lower piece of data bag is stored into the data window.It is this
By way of adding to data window queue m_udpWindow or removing sheet data bag so that data window queue m_
States of the udpWindow all the time in dynamic adjustment, when the network condition of receiving terminal is fine, immediately returns to confirmation, from
And data window would not be occupied full, transmission of the transmitting terminal with regard to supported progress data；But if the network condition of receiving terminal
Bad, the return of confirmation will be slow, so that the data window of transmitting terminal may be occupied full, so as to cause to send
End stops the transmission of data.It can so avoid connecing by the transmission rate regulation of transmitting terminal to the maximum network speed of receiving terminal
There is the phenomenon of process collapse in receiving end.
Further, after by all sheet data bag end of transmissions, when receiving terminal receives each sheet data bag, root first
According to the index value of each sheet data bag, each sheet data bag is ranked up according to the order from small arrival, and each sheet data bag is protected
PacketList queues are stored to, so as to ensure the succession of whole packet.
Then the bof values of first sheet data bag are obtained, judge whether the bof values are 1, if the bof values are 1,
It is starting sheet packet to determine first sheet data bag.
Equally, the eof values of first sheet data bag are obtained, judge whether the eof values are 1, if the eof values are 1,
It is also end sheet data to determine first sheet data bag.So then illustrate that first sheet data bag is complete packet, by the
One sheet data bag removes from packetList queues.
Conversely, when if eof values are not 1, continue to search the sheet data bag that eof values are 1 in packetList queue sequences, look into
After finding the sheet data bag that eof values are 1, then using the sheet data bag as end sheet data bag, then a complete UDP message
Bag just includes：First sheet data unwraps all sheet data bags to begin untill the sheet data bag.It should be noted that：From first
The index value that individual sheet data unwraps all sheet data bags to begin untill the sheet data bag is that consecutive order increases certainly.If from
The index value that one sheet data unwraps all sheet data bags to begin untill the sheet data bag is not that continuous order increases certainly, then
This UDP message bag is also incomplete.
For example the index value that the index value of first sheet data bag is the sheet data bag that 0, eof values are 1 is 5, then if
Should be included by unwrapping all sheet data bags of the beginning untill the sheet data bag from first sheet data by three, these three sheet data bags
Index value should be respectively 2,3,4, the UDP message bag so eventually formed is exactly complete packet.
But if the index value of these three sheet data bags is respectively 2,3,6, that UDP message bag eventually formed is not just
Complete packet.
So, receiving terminal is just completed to live data restructuring, and the decoding of audio frequency and video can be carried out to live data and is broadcast
Put.Compared with prior art, the time delay of this transmission method is reduced to 1~2s from 10s, and meeting the interactive of instantaneity needs
Ask.
Embodiment two
Corresponding to embodiment one, the present embodiment provides a kind of device for transmitting data, as shown in Fig. 2 described device includes：
Loading unit 21, collecting unit 22, the first judging unit 23, sharding unit 24 and transmission unit 25；Wherein,
In this step, when wanting to carry out interactive with main broadcaster because of user, it is necessary to which carrying out even wheat, user with main broadcaster needs to main broadcaster
The wheat request of the company of transmission, main broadcaster have received after this connects wheat request, and main broadcaster and user will then enter in same interactive direct broadcasting room, described
It can be Lian Maifang that interactive direct broadcasting room, which is different from the current interactive direct broadcasting room just in live direct broadcasting room, the present embodiment of main broadcaster,
Between.
Specifically, include referring to Fig. 3, the loading unit 21：First acquisition unit 31 and loading subelement 32, it is described to add
Subelements 32 are based on the even wheat request, will by calling the loading built-in function LoadLibrary of Windows operating system
DouyuInterActive.dll is as the parameter for connecting wheat service module so as to will connect wheat service module douyuInterActive
In the company's of being loaded onto wheat server.Company's wheat server in the present embodiment can be live companion.
Then the establishment interaction interface Service Instance function that even wheat service module provides is called
CreateInteractiveSdkInstance, to create an interactive even wheat service module interface
IDouyuInterActiveSdk。
So login identification ID of the acquisition of first acquisition unit 31 user and main broadcaster are current just in live live room ID；
Load subelement 32 and be based on interactive even wheat service module interface, be additionally operable to according to the login identification ID and live room ID
The live data of the interactive data of the user and the main broadcaster is loaded onto in the interactive direct broadcasting room.
After main broadcaster and user are in interactive direct broadcasting room, collecting unit 22 is used to gather living broadcast interactive in interactive direct broadcasting room
Data packet.The living broadcast interactive packet includes：The interactive data of user, the live data of main broadcaster and the interactive number of main broadcaster
According to these data can be video data and voice data, and the living broadcast interactive data include multiple packets.
Here, because when being carried out data transmission using udp protocol, the UDP message headers of live data transmission are in network
In hierarchical mode, UDP is in transport layer, and its lower floor is IP network layer, during to data transfer to IP network layer, the first judging unit
23 also need to judge the packet size whether beyond MTU MTU capability value；If the packet is big
The small capability value beyond the MTU, sharding unit 24 then carry out burst to the packet, form each sheet data bag.Wherein, institute
The capability value for stating MTU is 576 bytes.
During appearing in each sheet data bag of transmission, because certain reason causes some sheet data bag to be lost
Lose, or in receiving terminal, because receiving the reasons such as buffering area is full, cause each sheet data bag to be dropped in receiving terminal, then will
Cause whole big packet imperfect, so as in the Internet of receiving terminal by the situation of whole data packet discarding, described device
Also include：Second acquisition unit 26, the second judging unit 27 and indexing unit 28；Wherein,
Second acquisition unit 26 is used for the integer vernier value sended for obtaining current slice packet, the current slice packet
For any piece of data bag in each sheet data bag；Second judging unit 27 is used to judge the whole of the current slice packet
Whether type vernier value sended is consistent with the initial value of default transmission station location marker；Indexing unit 28 is used in the current slice
In the case that the integer vernier value sended of packet is consistent with the initial value of default transmission station location marker, the first mark is utilized
The starting sheet data that current slice packet described in code labeling is.
The second acquisition unit 26 is additionally operable to obtain the sizes values sizeToSend of current slice packet, the current slice
Packet is any piece of data in each sheet data bag；Second judging unit 27 is additionally operable to described in judgement
Whether sended, the sizeToSend meet sended+sizeToSend=packetSize, if satisfied, the mark is single
Member 28 is then end sheet data bag using current slice packet described in the second mark code labeling；Wherein, the packetSize is
The sizes values of the current slice packet.
In the present embodiment, the default initial value for sending station location marker is 0, and first identification code is the lowest order of byte
Bof, the second identification code are the second bit eof of the byte；That is, when integer vernier value sended is 0, expression is current
Sheet data bag is starting sheet packet, then with regard to bof be 1.
As sended+sizeToSend=packetSize, current slice packet is represented to terminate sheet data bag, then
It is 1 with regard to eof.
If current sheet data is unsatisfactory for above-mentioned two situations, eof and bof are 1, and it is middle to represent current sheet data
Sheet data bag.In general, when the sizes values of packet are less than MTU capability value, it is 1 feelings that eof and bof, which just occurs,
Condition.
Thus starting sheet packet, intermediate packet and sheet data bag progress clearly differentiation can be terminated.
After forming each sheet data bag, transmission unit 25 utilizes each sheet data described in UDP UDP sequential deliveries
Bag.
Here, when transmission unit 25 using udp protocol because being carried out data transmission, it is possible that out of order situation, than hair
The sheet data bag sent is 1,2,3；And the sheet data bag that receiving terminal receives is probably 1,3,2；So in order to out of order in appearance
In the case of, receiving terminal correctly can be also combined to packet, it is necessary to add index value to each sheet data bag.
Specifically transmission unit 25 adds to each sheet data bag successively according to the transmission order of each sheet data bag
Index value；The index value is incremented by according to default incremental spacing from default initial index value.For example initial index value is 0,
When incremental spacing is 1, then when sending first sheet data bag, the index value of first sheet data bag is just 0；Second piece number
Index value according to bag is 1, the like.Receiving terminal, even if there is out of order situation, also may be used after these sheet data bags are received
To carry out being correctly ordered combination to each sheet data bag according to index value.
The transmission unit 25 judges the data window queue m_ pre-established when transmitting current slice packet
In udpWindow whether available free data window, if the idle data window be present, transmit current slice packet,
And the current slice packet is preserved into the data window of free time.If, ought in the absence of the idle data window
Anter data pack buffer is in data queue to be sent.The current slice packet is any a piece of in each sheet data bag
Packet.
In the present embodiment, the data window queue includes multiple data windows, and the idle data window can also
Referred to as currently there are the data window or sliding window of capacity.The capacity of the default data window queue is 255 bytes,
That is the total capacity of the idle data window is 255 bytes.
Further, after current slice packet is transmitted, transmission unit 25 is additionally operable to：Create timer；The timer
Time can preset, the time of timer is 1s in the present embodiment；The current slice packet is stored to the number
According in window queue；After receiving terminal receives current slice packet, the index value of the current slice packet is obtained, and be based on institute
The confirmation that index value returns to the current slice packet to transmitting terminal is stated, the confirmation includes：ACK confirms bag.
Judge the confirmation that receiving terminal returns whether is received in default timing, if receiving the confirmation
Information, then the current slice packet is deleted in the data window queue, and delete the timer.If it is not received by institute
Confirmation is stated, in addition to：Continue to transmit the current slice packet, and the re-transmission position of the current slice data packet header is set
Re-transmission ident value is set to, the re-transmission ident value could be arranged to 1, and reset the timer.Thus can be according to confirmation
Mechanism and retransmission mechanism avoid the occurrence of packet loss phenomenon.
So correspondingly, receiving terminal obtains data window team when it is 1 current slice packet to receive re-transmission ident value
Minimum index value in row, judges whether the index value of the current slice packet is more than minimum index value, if being more than, then it represents that
Current data packet is to need packet to be processed；If it is less than, then it represents that the current slice packet is the packet for repeating transmission
(having received before), then directly abandon the current slice packet.
In addition, in order that transmitting terminal can control transmission rate, when receive receiving terminal return confirmation after, root
The index value of current slice packet is obtained according to confirmation, deleted based on the index value in the data window queue described in
Current slice packet, so that the data window that current slice packet takes is in idle condition, it can thus transmit down
Piece of data bag, after transmitting lower piece of data bag, and lower piece of data bag is stored into the data window.It is this by number
The mode of sheet data bag is added or removed according to window queue m_udpWindow so that data window queue m_udpWindow is all the time
State in dynamic adjustment, when the network condition of receiving terminal is fine, immediately returns to confirmation, so as to data window just not
It can be occupied full, transmission of the transmitting terminal with regard to supported progress data；But if the network condition of receiving terminal is bad, confirmation
Return will be slow, so that the data window of transmitting terminal may be occupied full, so as to cause transmitting terminal to stop the biography of data
It is defeated.Receiving terminal can so be avoided process occur and collapsed by the transmission rate regulation of transmitting terminal to the maximum network speed of receiving terminal
Routed phenomenon.
Further, after by all sheet data bag end of transmissions, when termination receives each sheet data bag, first according to each
The index value of sheet data bag, each sheet data bag is ranked up according to the order from small arrival, and each sheet data bag is saved in
PacketList queues, so as to ensure the succession of whole packet.
Then the bof values of first sheet data bag are obtained, judge whether the bof values are 1, if the bof values are 1,
It is starting sheet packet to determine first sheet data bag.
Equally, the eof values of first sheet data bag are obtained, judge whether the eof values are 1, if the eof values are 1,
It is also end sheet data to determine first sheet data bag.So then illustrate that first sheet data bag is complete packet, by the
One sheet data bag removes from packetList queues.
Conversely, when if eof values are not 1, continue to search the sheet data bag that eof values are 1 in packetList queue sequences, look into
After finding the sheet data bag that eof values are 1, then using the sheet data bag as end sheet data bag, then a complete UDP message
Bag just includes：First sheet data unwraps all sheet data bags to begin untill the sheet data bag.It should be noted that：From first
The index value that individual sheet data unwraps all sheet data bags to begin untill the sheet data bag is that consecutive order increases certainly.If from
The index value that one sheet data unwraps all sheet data bags to begin untill the sheet data bag is not that continuous order increases certainly, then
This UDP message bag is also incomplete.
For example the index value that the index value of first sheet data bag is the sheet data bag that 0, eof values are 1 is 5, then if
Should be included by unwrapping all sheet data bags of the beginning untill the sheet data bag from first sheet data by three, these three sheet data bags
Index value should be respectively 2,3,4, the UDP message bag so eventually formed is exactly complete packet.
But if the index value of these three sheet data bags is respectively 2,3,6, that UDP message bag eventually formed is not just
Complete packet.
So, receiving terminal is just completed to live data restructuring, and the decoding of audio frequency and video can be carried out to live data and is broadcast
