Time network, RTN) or the peer to peer network (pear-to-pear, P2P) that passes through.
RTN is a kind of network architecture for aiming at real-time Transmission and designing, and is reorganized between the data center in the whole world
Node is connected with each other and dispatches, one layer of new virtual network is constructed on the basis of existing public internet.Carrying out audio-video
When call, RTN in real time according to the connection of each node and status transmission, load state and distance and response time to user,
Audio-video optimal scheme, most unobstructed transmission path thus reach the quality assurance rank of real-time Transmission needs.Come using RTN
Audio-video is transmitted, is similar to and rents private network transmission, operation cost is higher.
P2P is a kind of Distributed Application framework that task and workload are distributed between fellow.Carrying out audio-video
When call, two user terminals conversed are respectively by address Internet protocol (internet protocol, IP) of opposite end
And port, IP address and port, pass through carry out audio video transmission by P2P as a purpose.Due to being passed using public internet
Defeated, without renting private network, therefore operation cost is cheap.But due to using public internet, so in audio video transmission
When link-quality, for example, bandwidth, time delay and delay variation etc. are unable to get guarantee.In addition, may not between two user terminals
It can be realized P2P to pass through.For example, for Internet Protocol Version 4 (internet protocol version 4, IPV4) user
Terminal, if can be realized P2P and pass through, depend primarily on network address translation (network address translation,
NAT) device type.When the NAT device used by the user terminal of two IPV4 is symmetric form, P2P passes through success rate pole
It is low.
Real-time audio and video call scheme existing in the prior art, such as the real-time audio and video based on proprietary cloud service framework
Call solution, the program are similar to the solution using real transport networks, can be in high-resolution, high frame per second and height
Under the communication quality of code rate, good audio-video experience is provided.But due to needing to build or rent real transport networks, operation
Higher cost.
In another example can choose the real-time audio and video solution of RTN and P2P when originated call, the program is in originated call
Shi Jinhang peer to peer network passes through trial, selects work on peer to peer network after passing through successfully, otherwise selects work in reality
When transmission network on.The program can be selected in originated call, suitably consider operation cost and user's audio-video
Experience.But real transport networks or peer to peer network have once been selected in originated call, it is subsequent just to switch.
Even if the link-quality of peer to peer network is up to standard after selecting real transport networks；Alternatively, after having selected peer to peer network,
The link-quality of peer to peer network is deteriorated, even it is not up to standard, it cannot all reselect.Therefore, if what when originated call, selected
It is real transport networks, then higher operation cost will be generated；And if what when originated call selected is peer to peer network,
Poor user's audio-video experience may then be generated.

RTN, then it is switched to from RTN the process of P2P, similar as above, details are not described herein.
It should be noted that the QoE mentioned in text, is intended to indicate that user to the Quality of experience of audio-video, including resolution
Rate, frame per second and code rate.It preferably, further include video mean opinion score (video mean opinion score, VMOS).Its
In, resolution ratio refers to pixel number included in inches, it reflects the clarity of image.Frame per second is referred to as frame
Continuously there is frequency (rate) over the display in bitmap images, it reflects the fluency of video.Code rate refers to that data are transmitted
When the unit time transmission data bits.Video mean opinion score namely VMOS have reacted the subjective video experience of user,
It is according to video quality, operating experience and to play experience determination.
The QoS mentioned in text, be intended to indicate that transmission audio-video backbone network link communication quality, including bandwidth, when
Prolong, delay variation and packet loss.Wherein, bandwidth, referring in the unit time usually can carry out table by the data volume of link with bps
Show.Time delay refers to that a message or grouping are transmitted to the time required for the other end from one end of a network.Delay variation,
Refer to the variation of time delay.Packet loss refers to that lost data packet number in test accounts for the ratio of transmitted data group.
