Its embodiment, shall fall within the protection scope of the present invention.
In a first aspect, the embodiment of the present invention provides a kind of live broadcasting method, the net cast in drawing stream address can be carried out
Turn to push away, is provided using Duo Jia CDN service manufacturer to viewer end and draw stream service, to effectively improve the disaster tolerance performance of network direct broadcasting.
As shown in Figure 1, the live broadcasting method that the embodiment of the present invention provides can include:
S11 obtains the former of live streaming and draws stream address；
Specifically, the live streaming in the present embodiment is based on CDN network, the net cast that main broadcaster end is recorded uploads to CDN plug-flow
Node, and the drawing stream node nearest apart from viewer end is buffered to by CDN network, to make viewer end from nearest drawing stream node
Pull live stream, viewing corresponding video live streaming.Original described in this step draws stream address to refer to the CDN edge nearest apart from viewer end
The address of corresponding video live streaming is provided on node for viewer end.The corresponding node in the address may provide simultaneously for multiple viewer ends
Net cast stream, the corresponding live stream of each viewer end.
S12 shifts the former live streaming circulation for drawing preset quantity in stream address onto purpose and draws stream address, formed updated
Draw stream address list；Wherein, the purpose draws stream address to belong to different content distributing network CDN factories from the former drawing stream address
Quotient；
Since the CDN service that each CDN service manufacturer provides has the advantages that respective and deficiency, in this step, will be broadcast live
Drawing stream address change or expanded, the present count that will be used to provide to viewer end in the former CDN node drawn at stream address
The live streaming circulation of amount, which is shifted onto, draws stream address from the former purpose for drawing the stream CDN manufacturer of address different, forms updated drawing stream ground
Location list.The quantity of live stream for carrying out turning to push away, which can according to need, to be configured and adjusts, and can both only relate to former draw stream ground
A part of live stream in location alsos relate to the former whole live streams drawn in stream address.Optionally, according to specific needs, mesh
Drawing stream address quantity can for one or more, corresponding CDN manufacturer can be one or more families, as long as with original draw stream ground
CND manufacturer belonging to location is different, and the embodiment of the present invention does not limit this.
S13, when viewer end draws stream viewing live streaming, Xiang Suoshu viewer end provides the updated drawing and flows address list,
So that the viewer end draws stream viewing live streaming from updated drawing stream address.
In this step, when viewer end, which is drawn, to flow, updated drawing can be provided to viewer end and flow address list, viewer end is used
Family can flow one drawing of selection in address list from updated drawing and flow address watching video live broadcast.
The live broadcasting method that the embodiment of the present invention provides can shift the former live streaming circulation for drawing preset quantity in stream address onto
Purpose draws stream address, draws stream address and purpose that stream address is drawn to provide live streaming to each viewer end jointly from original and draws stream.In this way, due to
Original draws stream address and purpose that stream address is drawn to be belonging respectively to different CDN manufacturers, even if the CDN that one of CDN manufacturer provides is drawn
Stream service is broken down, and still some spectators can continue to watch video by the drawing stream service that other CDN manufacturers provide
Live streaming, not will cause the case where all viewer ends can not all watch, to substantially increase the disaster tolerance performance of network direct broadcasting.
Optionally, the case where live streaming in the embodiment of the present invention both may include main broadcaster's unicast also may include main broadcaster's sight
The case where crowd's interaction live streaming, the embodiment of the present invention does not limit this.Particularly, interaction live streaming is carried out for main broadcaster and spectators
The case where, since main broadcaster and spectators carry out even wheat interaction and the plug-flow end node of main broadcaster end and CDN service are needed to provide corresponding branch
It holds, so that the quantity that can allow to the CDN manufacturer met the requirements greatly reduces, disaster tolerance is had a greatly reduced quality.In view of this, in this hair
In bright some embodiments, while selecting suitable CDN manufacturer for main broadcaster end, it can turn to push away by live stream, make more
More CDN manufacturers can provide corresponding drawing stream service jointly for viewer end, diversify risks, therefore can greatly improve drawing stream end
Disaster tolerance performance.
Specifically, in step s 11, cloud server terminal can know that main broadcaster end is recorded by the live streaming request that main broadcaster end is sent
Net cast be distributed by which CDN service manufacturer, and disposed according to the position of viewer end from CDN service manufacturer
It draws and selects a drawing stream node nearest from the viewer end as original drawing stream node in stream node, corresponding address is that former draw is flowed
Address, to know that the former of a live stream draws stream address.
After getting original drawing stream address, in step s 12, the former drawing can be flowed by intermediate node default in address
The live streaming circulation of quantity shifts other onto and draws stream address, i.e. purpose draws stream address.Wherein, intermediate node can be for by live stream
Stream address is drawn to turn to shift various equipment or the server etc. that another draws stream address onto from one.The quantity of intermediate node can be one
A or multiple, the embodiment of the present invention does not limit this.
Specifically, in one embodiment of the invention, former draw is flowed present count in address by intermediate node
The live streaming circulation of amount shifts purpose onto and draws stream address can include: pulls the live streaming from the former drawing stream address by intermediate node
Stream；In the case where the intermediate node successfully pulls the live stream, Xiang Suoshu intermediate node indicates that the live stream is corresponding
Purpose draw stream address；The live stream pulled is pushed to the purpose by the intermediate node and draws stream address.
That is, the former drawing stream address that cloud server terminal can will acquire passes to intermediate node, intermediate node is received
Video can be pulled from original drawing stream address after drawing stream address to the original flow to the intermediate node.Moreover, intermediate node can be with
Drawing stream mode is reported to cloud server terminal at any time, if intermediate node successfully pulls the video flowing, cloud server terminal can be to this
Intermediate node sends purpose and draws stream address, and intermediate node is after receiving purpose and drawing stream address, the video flowing that can will pull
It is pushed to the purpose and draws stream address.Certainly, in other embodiments of the invention, cloud server terminal, which can also first draw original, flows address
And purpose draws stream address to inform intermediate node, and pulling and pushing for stream is directly broadcast live by intermediate node.Implementation of the invention
Example does not limit this.
It is optional you, in various net casts, each intermediate node simultaneously multiple live streams may pull and
Push.These are pulled and push is possible to success, it is also possible to failure.In one embodiment of the invention, in intermediate node
In the case where pushing away failure to live streaming circulation, it can detecte whether main broadcaster end terminates to be broadcast live；It is not at the main broadcaster end
In the case where live streaming, intermediate node can be continued through, live stream is carried out turning to push away.Optionally, during turning to push away, turned
The intermediate node pushed away can be always one and remain unchanged, and can also switch to another intermediate node by an intermediate node,
The embodiment of the present invention does not limit this.
For example, in one embodiment of the invention, main broadcaster end uploaded videos live streaming, the address Yuan Laliu is add1,
It is broadcast live by intermediate node M1 and turns to push away, net cast duplication is turned to shift purpose onto and draw to flow address add2.Intermediate node M is attempted
Turn to push away failure after a period of time, and is reported to cloud server terminal and turn to push away failure.Cloud server terminal finds that active termination is not straight at main broadcaster end
It broadcasts, then indicates that intermediate node M again attempts to draw from add1 and flow and be pushed to add2.If intermediate node M's turns to push away and still fail,
Then cloud server terminal can indicate intermediate node interval preset duration, such as be spaced after the Fibonacci sequence second plug-flow again.Alternatively,
Cloud server terminal can indicate that intermediate node N replacement intermediate node M progress is above-mentioned and turn push operation.
After detecting that main broadcaster end terminates live streaming, cloud server terminal can notify intermediate node to stop corresponding drawing and flow and push
Work.
Further, since original draws stream address, purpose to draw stream address and intermediate node large number of, it is staggered into network,
In order to make to draw flow distribution more reasonable, make each intermediate node load balancing, a kind of embodiment according to the present invention, present invention reality
The live broadcasting method for applying example offer, which may also include that, receives the node load information that the intermediate node reports；It is negative according to the node
Information carrying breath is scheduled the intermediate node for turn push operation, so that the intermediate node load balancing.
For example, intermediate node P1 is responsible for that some live streaming circulation of former drawing stream address add3 is shifted onto purpose and drawn to flow address simultaneously
Add4, and shift former some live streaming circulation for drawing stream address add5 onto purpose and draw stream address add6.Intermediate node P1 can determine
When report the load information for turning push mode and intermediate node P1 itself of this two-way live stream, such as CPU to make to cloud server terminal
With rate etc..If the CPU usage of intermediate node P1 is 80%, and the CPU usage of another intermediate node P2 is 30%,
Then a part of intermediate node P1 turn can be pushed away task and be transferred to intermediate node P2 completion by cloud server terminal, to mitigate middle node
The work load of point P1, and make full use of intermediate node P2 makes entirely to turn pushing system more balanced.
It primarily illustrates how the live streaming at former drawing stream address to circulate by intermediate node above and shifts purpose into drawing stream
Location.However for viewer end, being postponed by such turn, the address that they obtain live stream is just changed, in order to
The live video program is smoothly watched, viewer end needs to obtain the drawing stream address for turning to postpone.For this purpose, in step s 13, working as spectators
When stream viewing live streaming is drawn at end, need to provide updated drawing stream address list to viewer end.
Specifically, in one embodiment of the invention, when viewer end draws stream viewing live streaming, being provided more to viewer end
Drawing stream address list after new may include following steps:
The drawing stream request of viewer end is received, it is described to draw the live video mark that the live streaming to be watched is carried in stream request；
With determining updated drawing stream corresponding to the live streaming to be watched of viewer end according to live video mark
Location list；
The updated drawing, which is provided, to the viewer end flows address list.
For example, in one embodiment of the invention, viewer end T1 will watch certain net cast A, net cast A's
It is addA1 that original, which draws stream address, carries out turning to postpone to the net cast A at addA1, the live stream of a part of net cast A is turned
AddA2 is shifted onto.Viewer end T1 is sent to cloud server terminal draws stream request, and the live streaming of the live streaming to be watched is carried in drawing stream request
Video identifier A.Cloud server terminal can identify A according to the live video and determine that after drawing circulation to push away, address is flowed in updated drawing
List includes that former draw flows address addA1 and purpose drawing stream address addA2, and updated drawing is then flowed address list to spectators
T1 is held to send, so that viewer end T1 obtains corresponding video according to updated drawing stream the address addA1 or addA2 in the list
Live streaming.
Optionally, in the embodiment of the present invention, the drawing stream address for including in updated drawing stream address list can be one
A or multiple, the embodiment of the present invention does not limit this.Flowing in address list when updated drawing includes that address is flowed in multiple drawings
When, updated drawing stream address list corresponding to the live streaming to be watched of viewer end is determined according to live video mark
Can further comprise:
Multiple updated drawings corresponding to the live streaming to be watched of viewer end are determined according to live video mark
Flow address；
The multiple updated drawing stream address is sorted according to preset rules, updated drawing is formed and flows address list.
In this manner it is possible to flowing address for multiple drawings provides priority, viewer end can be preferentially using being arranged in front
Draw stream address.Optionally, it will draw be ranked up preset rules of stream address can according to spectators' end subscriber user gradation, CDN
Situations such as service feature of service facility, formulates.For example, in one embodiment of the invention, it can be by CDN service manufacturer
Stage charge is used as a preset rules, when some draws the use duration of stream address or is taken using flow apart from corresponding CDN
When the charging skip list value of business manufacturer is less than preset threshold, the corresponding priority for drawing stream address of the CDN service manufacturer can be reduced,
Make viewer end that other drawing streams address preferentially be selected to be charged so that stream distribution resource is drawn by equilibrium Duo Jia CDN manufacturer according to CDN manufacturer
