Abstract
The invention provides a could computing virtual machine media stream broadcasting method and a system. According to the method, a relay component, as an important part for forwarding and caching of the media stream, is added in a cloud computing system, and the broadcasted media stream is subjected to transferring of the relay component instead of being directly transmitted to a plurality of broadcasting-accepting virtual machines through a master broadcasting virtual machine. So, transaction handling capacity of the master broadcasting virtual machine and data volume of an IO port can be reduced; secondly, the relay component can create a plurality of relay groups, the relay groups exist in a mutually independent manner, the virtual machines to be contained in the relay groups can be configured flexibly, free combination of the broadcasting virtual machines is realized, and a media stream broadcasting function of different classrooms and different network segments is also realized; and cloud operating terminals are free from installing a broadcasting software, and are all managed uniformly by a cloud computing management system, thus, management is facilitated more and maintenance work is optimized, and manpower and material resources are reduced.
Description
Technical field
The present invention relates to the management domain of cloud computing virtual machine, more specifically, relate to a kind of cloud computing virtual machine media stream broadcast method and system.
Background technology
Cloud computing is a kind of computation schema of resource-sharing, and this pattern provides access to netwoks available, easily, as required, supports to pay by use amount, and the resource that cloud computing provides can be supplied by Quick.In education sector, in order to improve the experimental situation of computer, a lot of school has also introduced cloud computing system, exists, provide the cloud desktop services of virtual machine with the form of privately owned cloud.
At present, in the experimental calculation machine system of education sector, very common a kind of form is exactly: in a computer-experiment classroom, there is a teacher's computers, broadcast software has been installed, realize broadcasting to the computer in whole classroom at the desktop of teacher's computers, each student computer is the desktop contents of real teacher's computer.By the mode that this desktop is broadcasted, teacher can demonstrate relevant computer operation and relevant teaching explanation to student.
Along with the develop rapidly of cloud computing, cloud service demand is increasing, also introduces cloud computing system in education sector, and the cloud computing system of modal education sector is to provide the privately owned cloud system of cloud desktop services.Cloud desktop services system namely adopts Intel Virtualization Technology by cloud computing system, replaces original PC personal computer with virtual machine, realizes convenient management, easy to maintenance and cost-effective object.But due to the particularity that teaching process has it to apply, the cloud computing system of serving education sector still faces many difficulties.In current cloud computing system, neither one solves the broadcast capability of the virtual machine of the process of attending class very well.
Summary of the invention
The invention provides a kind of cloud computing virtual machine media stream broadcast method, realize the function of a virtual machine to multiple virtual machine broadcast medium flow data.
Another object of the present invention is the cloud computing system providing a kind of this cloud computing virtual machine media stream broadcast method of application.

S4: broadcast virtual machine by remote transfer protocol, is sent to cloud operating terminal the media stream data received from relay component, and the media stream data of cloud operating terminal display is consistent with main broadcaster's virtual machine;
S5: main broadcaster's virtual machine terminates broadcast to cloud computing management system request, and relay component closes this broadcast relay group, and each virtual machine is restored to independently virtual machine.
In the present invention, relay component is added in cloud computing system, as the forwarding of Media Stream and the vitals of buffer memory, the Media Stream of broadcast is not directly sent to multiple virtual machine of being broadcast by main broadcaster's virtual machine, and be through relay component switching process, the transaction amount of main broadcaster's virtual machine and the data volume of IO port can be reduced; Relay component can create some relaying groups, separate existence between relaying group, can the flexible configuration relaying group virtual machine that will comprise, and realizes the independent assortment of broadcasting virtual machine, realizes the media stream broadcast function of different classroom and different segment.
A kind of cloud computing system, comprising:
Cloud computing management system, for managing and control resource and the task process of whole cloud computing system;
Virtual machine, adopts cloud computing Intel Virtualization Technology to build virtual machine in computing node; In media stream broadcast system, be divided into main broadcaster's virtual machine, broadcast virtual machine, independent virtual machine;
Relay component, for giving some intermediate members by broadcasting virtual machine main broadcaster's virtual machine media stream broadcast, forwards and buffer memory media stream data, the corresponding main broadcaster's virtual machine IP in supervisory relay group and broadcast virtual machine IP group.
Further, described relay component is made up of some relaying groups, and each relaying group comprises main broadcaster's virtual machine and somely broadcast virtual machine, and relay component and virtual machine are by cloud computing management system unified management; Main broadcaster's virtual machine has the right to control to be broadcast virtual machine to be forced to enter the state broadcast, by the desktop contents broadcasting virtual machine and can only show main broadcaster's virtual machine.
Further, there is multiple relaying group in cloud computing system, a virtual machine at a time can only belong to a relaying group; When a relaying group is removed after to the binding of certain virtual machine, this virtual machine can become the member of other relaying group.
Further, described relay component buffer memory and relay media stream data, the media stream data of main broadcaster's virtual machine is broadcast virtual machine forwarding media flow data through the buffer memory of relay component to multiple, thus ensures that the transmission of media stream data is smooth and easy.
Further, the virtual machine IP in described relaying group belongs to same VLAN, and the media stream data of main broadcaster's virtual machine only has the virtual machine of being broadcast of same relaying group just to receive and obtain, and other relaying group and independent virtual machine can not receive.
Further, when the virtual machine of a relaying group needs the broadcast medium flow data obtaining another relaying group, can apply for adding another relaying group, after another relaying group is agreed to, form a wider broadcast relay group.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
The present invention by increasing relay component, as the forwarding of Media Stream and the vitals of buffer memory in cloud computing system.The Media Stream of broadcast is not directly sent to multiple virtual machine of being broadcast by main broadcaster's virtual machine, and is through relay component switching process.The transaction amount of main broadcaster's virtual machine and the data volume of IO port can be reduced like this; Secondly, relay component can create some relaying groups, separate existence between relaying group, can the flexible configuration relaying group virtual machine that will comprise, and realizes the independent assortment of broadcasting virtual machine, realizes the media stream broadcast function of different classroom and different segment; Again, cloud operating terminal is without the need to installing broadcast software, and all by cloud computing management system unified management, convenient management and Optimal Maintenance work, reduce manpower and materials.
