Fig. 5 shows a kind of data transmission method based on view networking provided by the embodiments of the present application, and this method can be applied
In view networked terminals, when first view networked terminals to second view networked terminals transmission objectives data packet, may comprise steps of:
Step 501: the first view networked terminals are via view networked server based on the data transfer mode of transparent transmission to institute
It states second and successively transmits multiple subdata packets depending on networked terminals；Wherein, the multiple subdata packet belongs to the target packet,
The multiple subdata packet includes the first subdata packet, and calling channel is carried in the first subdata packet and actively establishes request,
The calling channel is actively established request and is called for triggering the second view networked terminals to view networked server transmission
Path Setup request, with the calling transmission channel established between the second view networked terminals and the first view networked terminals.
In a kind of possible embodiment, in the first view networked terminals via view networked server based on transparent transmission
Before data transfer mode successively transmits multiple subdata packets depending on networked terminals to described second, the method also includes:
Described first is logical depending on whether having built up calling transmission between networked terminals depending on networked terminals judgement and described second
Road；If it has been established that if pass through target packet described in the calling transmission channel transfer；If not establishing, described first
It is successively transmitted to described second depending on networked terminals via depending on networked server based on the data transfer mode of transparent transmission depending on networked terminals
Multiple subdata packets.
In step 501, described first the target packet is divided into the multiple sons being sized depending on networked terminals
Data packet, and to the multiple subdata packet number consecutively；According to the number of each subdata packet with sequence from small to large successively
The second view networked terminals are pass-through to, the first subdata packet is the subdata packet that first transparent transmission goes out.Purpose be in order to
It is as fast as possible will calling channel actively establish request be sent at the second view networked terminals so that second view networked terminals to
The view networked server sends calling Path Setup request, is networked with establishing the second view networked terminals and first view
Calling transmission channel between terminal.
In a kind of possible embodiment, if described first does not receive the view depending on networked terminals within the set time
The calling transmission Path Setup success message that networked server is sent, then add in next subdata packet to transparent transmission
It calls channel and actively establishes request, built to described depending on networked server transmission calling channel with triggering described second depending on networked terminals
Vertical request.
For example, if after the first subdata packet sends out, the view networking clothes are not received within the set time
It is engaged in the calling transmission Path Setup success message that device returns, and is had been sent at this time towards second depending on the data packets of networked terminals
Tenth subdata packet, then request is actively established in addition calling channel in the 11st subdata packet, by the 11st subdata
Packet is sent to the second view networked terminals, sends calling channel to trigger the second view networked terminals to the view networked server
Establish request.
Step 502: when described first depending on networked terminals receive it is described view networked server send calling transmission channel
It is successfully established after message, the first view networked terminals is regarded into the data transfer mode of networked terminals by transparent transmission to described second
Mode is switched to by way of the calling transmission channel transfer to continue to transmit the target packet.
For example, if first depending on networked terminals receive it is described depending on networking send calling transmission Path Setup successfully disappear
Breath, illustrates that described second has built up depending on networked terminals and described first depending on the calling transmission channel between networked terminals.Cut-off
When receiving the calling transmission Path Setup success message, described first regards networked terminals for the subdata packet in target packet
It is dealt into the 4th subdata packet, then after distributing the 4th subdata packet, first switches to data transfer mode depending on networked terminals
By way of the calling transmission channel transfer, i.e., by the 5th subdata packet of calling transmission channel transfer and later
Subdata packet, until target packet end of transmission.
In simple terms, the first view networked terminals are represented with A, B represents the second view networked terminals.A is utilizing transparent transmission number
When sending the data to B according to transmission mode, one section of data with special characteristic can be added in data, to inform B: " please call
I ".Further, B calls interface of calls to call, i.e. B is actively established with A " call data transmission channel ".；Depending on networked server
Channel process is established in completion, Path Setup success after, view networked server by transmission the data packet with special characteristic come
Notify A and B.For A when transparent transmission mode is switched to method of calling, data transmission does not occur any pause.That is, A makes
Request B is completed while sending data with transparent transmission calls oneself.The process in calling transmission channel is entirely established, will not block A makes
Data are sent to B with transparent transmission mode.
