Preferably, comprising: datalink layer connection, tunnel layer, encryption and decryption layer, self adaptive transmission agreement data Layer, network articulamentum and network verification layer.
Preferably, said enciphered data unit is used for the terminal is encrypted to the data at terminal to the data and the high in the clouds in high in the clouds according to encryption level.
A kind of self adaptive transmission agreement stack processing method comprises step:
A: user's login, create control channel;
B: create the corresponding virtual passage as required, with disposal ability and the solicited message notification streams distributor of self;
C: the stream distribution device receives after the request, carries out adaptively according to the disposal ability of end and solicited message, finds the high in the clouds that service can be provided for the terminal, notifies this high in the clouds;
D: the corresponding virtual passage is created according to the solicited message of receiving in high in the clouds, after passage is created successfully, the result is issued the stream distribution device, and the stream distribution device is issued the terminal with the result;
E: the terminal begins to carry out data interaction after receiving that the passage success message is created in high in the clouds, by new establishment channel transmission data, is managed by aerial passage.
A kind of self adaptive transmission agreement stack treatment system comprises: terminal, stream distribution device and high in the clouds,
Said terminal is used for the request according to the user, creates tunnel, and user's request is sent to the stream distribution device;
Said stream distribution device is used for carrying out according to user's request adaptive, and is transmitted to high in the clouds;
Said high in the clouds is used for creating the corresponding virtual passage according to the solicited message of receiving, after passage is created successfully, the result is issued the stream distribution device, and the stream distribution device is issued the terminal with the result; The terminal receives high in the clouds and creates the passage feedback message, and the line data of going forward side by side is mutual.
The present invention compared with prior art; Have the following advantages: self adaptive transmission agreement provided by the invention can be according to factors such as the disposal ability of terminal equipment, network conditions; Rational virtual desktop with service end splits into different resources with application and transmits through different passages, and is assembled into complete desktop demonstration at terminal equipment.
According to the hardware capabilities at terminal and the transmittability of network, dynamically day positive protocol processes is used for constantly promoting user experience and resource occupation simultaneously.

Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
For ease of the present invention is better understood, make an explanation in the face of several technical terms down:
High in the clouds: the server that various application and desktop are provided.
Terminal: the software and hardware device that is installed on user side.
The desktop assembly unit: client will be integrated assembly unit from the data flow that the stream distribution device transmits, and be combined into user's desktop.
Stream distribution device: provide the service of appointment stream to provide and control program to the user.
See also self adaptive transmission agreement trestle composition shown in Figure 1, comprising: datalink layer connection (ISO), tunnel layer (MCS), encryption and decryption layer (SEC), self adaptive transmission agreement data Layer (APT), network articulamentum and network verification.Its composition is as shown in Figure 2, comprising: channel type unit, enciphered data unit, data cell.
The channel type unit mainly comprises, master control passage, sound channel, video channel, peripheral channel, application passage, desktop passage.
The master control passage is responsible for sending the request to virtual desktop and virtual application to server end, to using the whole process management may command of virtual desktop and virtual application.Create as required and discharge other tunnels.
Sound channel is responsible for transmitting audio data.
Video channel is responsible for transmitting video data.
Use passage and be responsible for transmitting the information of various virtual applications.
The desktop passage is responsible for the information of transfer of virtual desktop.
The enciphered data cell descriptions be type, the rank of AES.AES is divided into 3 high, medium and low three ranks of rank.High level AES uses 128 strong RC4 AES, and the terminal is all encrypted to the data at terminal to the data and the high in the clouds in high in the clouds.Other AES of middle rank uses 64 RC4 AES, and the terminal is all encrypted to the data at terminal to the data and the high in the clouds in high in the clouds.Low-level AES uses 64 RC4 AES, only the data from the terminal to high in the clouds is encrypted.
Data cell provides the data of effective self adaptive transmission agreement, and the beginning of data, ending and length.
The self adaptive transmission agreement handling process, referring to shown in Figure 3:
The first step: user's login, create control channel.
Second step: create the corresponding virtual passage as required, with disposal ability and the solicited message notification streams distributor of self.
The 3rd step: the stream distribution device is received after the request, carries out adaptive according to the disposal ability and the solicited message of end.Find the high in the clouds that service can be provided for the terminal, notify this high in the clouds.
The 4th step: the corresponding virtual passage is created according to the solicited message of receiving in high in the clouds.After passage is created successfully, the result is issued the stream distribution device, the stream distribution device is issued the terminal with the result.
The 5th step: the terminal begins to carry out data interaction after receiving that the passage success message is created in high in the clouds.By new establishment channel transmission data, manage by aerial passage.In this process high in the clouds can according to the ability of terminal equipment and instantly network environment desktop or application split different passages sent, on terminal equipment, carry out assembly unit at last, for the user represents a complete interface.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
