The audio/video information stream transmitted under interior video class opening replicates many parts in real time, while performing concurrent operations.
Further, it is connected by least one SFU with multiple second trunkings of outer layer net, is then completed and many
Communication of the individual second terminal equipment in webpage under video class opening, in addition to：Based on dynamic programming algorithm with it is most short
The mode that routing algorithm is combined, is connected by least one SFU with multiple second trunkings, to complete for multiple
Communication of the second terminal equipment in webpage under video class opening.Wherein, the second trunking is second terminal equipment
Access device, and the two be one-to-one relationship.
Further, backbone network carries out geographical position setting with outer layer net according to user's communication requirement.Thus, group is passed through
The flexibility of net improves the usability based on transnational, the ultralow delay communication of video class in webpage.
A kind of communication means based on transnational, the ultralow delay of video class in webpage that the present invention is provided.First eventually
In the webpage of end equipment under video class opening, backbone network is accessed by the first trunking, wherein, backbone network is at least
The network of one SFU composition；First terminal equipment is connected by least one SFU with multiple second trunkings of outer layer net
Connect, then complete with communication of multiple second terminal equipment in webpage under video class opening, wherein, outer layer net is the
The network for the trunking composition that one trunking can access with multiple second terminal equipment.This method can solve the problem that based on actual
The convenient sex chromosome mosaicism that the trans-regional real time multi-human of application scenarios is communicated, while so that many people communication has bandwidth low consumption characteristic
With the beneficial effect of the stability of communication linkage, further, user's communication usage experience can be obviously improved.
As shown in Fig. 2 being a kind of transnational, ultralow delay based on video class in webpage in one embodiment of the invention
Communication means application exemplary plot.
Specifically, positioned at Heilungkiang first terminal equipment in webpage under video class opening, by based on ground
The inquiry (GeoIP DNS) of position and the poll based on delay are managed, helps client to find best TURN to integrate
(Traversal Using RelayNAT, by Relay modes passing through NAT) is used as the first trunking, then by the first relaying
At least one SFU in equipment access backbone network.In the present embodiment, it is many that the first terminal equipment positioned at Heilungkiang to be communicated
Individual second terminal equipment is located at Zhejiang and Hong Kong respectively.Wherein, SFU is that one kind can flexibly receive any audio/video flow, and will
Audio/video flow replicates many parts in real time, the equipment for being forwarded to any recipient.Any user can regard the sound that itself to be distributed
Frequency stream is pushed to SFU, and reciever can optionally receive the audio/video flow handled by SFU according to self-demand.
First terminal equipment is received in webpage under video class opening by least one SFU in backbone network
Audio/video information stream；The audio/video information stream that first terminal equipment is transmitted in webpage under video class opening is multiple in real time
Many parts of system, while concurrent operations are performed, finally with multiple second terminal equipment communications.
Further, it is connected by least one SFU in backbone network with multiple second trunkings of outer layer net, after
And complete and communication of multiple second terminal equipment in webpage under video class opening, in addition to：Based on Dynamic Programming
The mode that algorithm is combined with shortest path first, is connected by least one SFU with multiple second trunkings, so as to complete
Into for multiple second terminal equipment communications.Wherein, outer layer net is that the first trunking can access with multiple second terminal equipment
Trunking composition network.
In the present embodiment, the mode being combined based on dynamic programming algorithm with shortest path first, positioned at Heilungkiang
One terminal device passage path 1 is communicated with the second terminal equipment in Zhejiang；First terminal equipment positioned at Heilungkiang passes through
Path 2 is communicated with the second terminal equipment in Hong Kong.Wherein, the second trunking is the access device of second terminal equipment,
And the two is one-to-one relationship.
To sum up, said system had both ensured enough outer layer trunkings and internal layer selection retransmission unit, for example, outer layer
Trunking can use SFU using TURN, internal layer selection retransmission unit.Then by above-mentioned multiple trunkings of outer layer and interior
Layer multiple selection retransmission units are distributed various regions at home and abroad and set up one big scale communication network on demand, and multiple because of outer layer
Interoperability between trunking and the multiple selection retransmission units of internal layer, a communication path most fast in network is found out
Afterwards, intercommunication relaying connection two ends can be passed through.
Further, the system is made up of outer layer net with inner layer net, it is possible to achieve based in webpage video class it is transnational,
The stability of point-to-point many people's linking communications of ultralow delay, and the point-to-point many people of reduction connect the loss of bandwidth.Wherein, first
Multiple trunkings composition outer layer net that trunking can access with least one second terminal equipment, and at least one selection turn
Bill member constitutes inner layer net in netted cluster form.
As shown in figure 3, being prolonged for a kind of in another embodiment of the present invention based on the transnational, ultralow of video class in webpage
The application exemplary plot of slow communication means.
, can real-time video call mutually between teacher specifically, in a Virtual Class, 2 teachers teach；Also
There are n students listening to the teacher, student can see two teachers；But academics and students can't see any student.Without using SFU
In the case of, signal intelligence is illustrated in fig. 3 shown below.It can be seen that, under point-to-point model, every teacher needs to send n+1 roads stream
(n student, additional another 1 teacher), receives 1 road stream (another 1 teacher), and every student receives 2 road streams (teacher's sum).But
It is that under SFU models, every teacher only needs to send 1 road stream to SFU, and SFU can be copied into n+1 roads stream, be sent to other
Owner.So, the transmission stream quantity of every teacher, 1 has been reduced to from n+1.
Further, it is assumed that teacher (host) quantity is few, and student (audience) quantity is a lot.So managed according to complexity
By by SFU, the transmission number of teacher being made to drop to O (1) from O (n), total fluxion of whole meeting can be made from O (n2) drop to
O (n), has totally dropped one-dimensional.That is, SFU realize teacher side need not very big upstream bandwidth, just can support many people realities
When video communication.
To sum up, a kind of communication means based on transnational, the ultralow delay of video class in webpage proposed by the present invention, is realized
Allow both equipment of TURN and SFU, it is whole with WebRTC (Web Real-TimeCommunication, webpage real-time Communication for Power)
Individual connection procedure and standard can be interconnected.In other words, during each reception data substantially on TURN and SFU, all make
With a virtual client；When sending data, a virtual client also using.Only difference is that TURN is right at one end
The direct transparent relay in one end, SFU is replicated to multiterminal route at one end, also more flexible.By simulating the point-to-point of WebRTC supports
Communication, to realize through server communication.And then the method provided by the invention realize multiple spot, trans-regional any intercommunication it is suitable
The property used.
Based on same inventive concept, a kind of communication based on transnational, the ultralow delay of video class in webpage is additionally provided
