Embodiment
Below in conjunction with Figure of description, a kind of destination object broadcasting method based on Intel Virtualization Technology that the embodiment of the present invention is provided, the embodiment of Apparatus and system describe.
A kind of destination object broadcasting method based on Intel Virtualization Technology that the embodiment of the present invention provides, as shown in Figure 2, specifically comprises the following steps:
S21: the arbitrary virtual machine in server receives the broadcast request that connected terminal sends;
Here, above-mentioned broadcast request is for broadcasting the destination object presenting on the current screen of above-mentioned terminal;
S22: after receiving broadcast request, to terminal, send default very first time stamp, with indicating terminal, preserve very first time stamp, and other virtual machines in announcement server send facility information and the very first time stamp of arbitrary virtual machine to the terminal of correspondence connection, with indication counterpart terminal, preserve very first time stamp, and connect according to facility information and arbitrary virtual machine;
S23: after destination object is processed, take with the second default timestamp and be sent in the lump all terminals that are connected with self, and the prolongation airtime of indicating each terminal to determine according to the second timestamp, the time interval that receives very first time stamp and the second timestamp and very first time stamp, the destination object after processing is processed to rear broadcasting again.
Preferably, in above-mentioned steps S21, for any one virtual machine in server, it is to know related content that the end side that is attached thereto presents, that is to say, it knows the destination object presenting on the terminal current screen being attached thereto, and like this, follow-up need be carried out being sent to all terminals that are attached thereto after relevant treatment to this destination object.
It should be noted that, above-mentioned destination object is actually the application interface of the current operation of end side demonstration, for example, can be static page, also can be the video data with sound, certainly, can also be other guide.
Preferably, in above-mentioned steps S22, for any one virtual machine in server, it,, after receiving the broadcast request that the terminal that is attached thereto sends, considers that network exists certain retardance conventionally, can send default very first time stamp to the terminal being attached thereto, like this, allow terminal be saved in this locality after receiving this very first time stamp, so that follow-up definite prolong reproduction time is used, and then guarantee the synchronized broadcasting of succeeding target object.
Here, the mode that any one virtual machine can the terminal by being attached thereto sends airtime message send the very first time and stab, and in this case, very first time stamp is carried in this airtime message, certain, can also adopt other send modes.
It should be noted that, obtain the time of delay that above-mentioned default very first time stamp can deduct by the current time of server setting, for example, in the current time of virtual machine, was 10 o'clock sharps, be that in the situation of 10 minutes, default very first time stamp is 9: 50 the time of delay of setting.Certainly, above-mentioned stamp of the default very first time also can obtain by other means, at this, will not enumerate.
Meanwhile, in order to realize cross-network segment synchronized broadcasting, any one virtual machine in server, after receiving above-mentioned broadcast request, also can notify other virtual machines by the virtual management unit in server (being virtual instrument), the terminal that allows other virtual machines connect to correspondence sends the facility information of this virtual machine (receiving the virtual machine of broadcast request) so that counterpart terminal according to relevant device information therewith virtual machine connect, for example, setting up Transmission Control Protocol connects.
In aforementioned this processing mode, during the virtual machine that is reception broadcast request at any one virtual machine, no longer, as prior art, destination object is first sent in server and is processed with other virtual machine places that lay oneself open to the same network segment, take the more resource of server; But the terminal that other virtual machines in announcement server connect to correspondence sends relevant device information, indicate counterpart terminal and oneself connect, like this, follow-uply directly send to all terminals that are connected with oneself after destination object is processed, in this process, other virtual machines only play forwarding effect, processing target object not, therefore, do not take the more resource of server, thus the load that has alleviated server.
In addition, in order to guarantee better the synchronized broadcasting of succeeding target object, other virtual machines also can send to the corresponding terminal connecting by above-mentioned very first time stamp, allow counterpart terminal preserve this very first time stamp, so that follow-up definite prolong reproduction time is used.
It should be noted that, for other virtual machines, the mode that they can send by the terminal connecting to correspondence connection message realizes, and in this case, carries facility information and the very first time stamp of above-mentioned virtual machine in this connection message.Here, the facility information of above-mentioned virtual machine specifically can comprise the IP address of this virtual machine and port numbers etc.
Further, in above-mentioned steps S23, for any one virtual machine in server, it after success and other-end connect, the characteristic of retardance Network Based, it is after processing destination object, be not to be directly sent to all terminals that are connected with self, but take same the second default timestamp, send in the past, be convenient to so follow-up definite prolongation airtime of each terminal, then according to this, extend airtime broadcasting destination object.Here, the second default timestamp can be the current time of server.
Particularly, for above-mentioned each terminal being successfully connected with any one virtual machine, can determine and extend the airtime by following manner: calculate the second timestamp, with the difference of very first time stamp and the time interval being carried out to the timestamp that summation operation obtains, and using the difference calculating as the prolongation airtime.Afterwards, then carry out a series of judgement flow process: extend the airtime and be less than at 0 o'clock judging, abandon destination object; Extend the airtime and equal at 0 o'clock judging, immediately the destination object after processing is processed to rear broadcasting again; Extend the airtime and be greater than at 0 o'clock judging, wait for and extending after the airtime, the destination object after processing is processed to rear broadcasting again, to realize each end side, synchronously play.
For example, the broadcast request that the VM1 of take receives PC1 transmission is example, suppose that above-mentioned very first time stamp is 9: 50, the second timestamp is 10: 10, and the time interval that PC1 receives very first time stamp and the second timestamp is 10 minutes, so, through aforesaid way, obtaining extending the airtime is 10 minutes, at this moment, PC1 need wait for 10 minutes again, and the destination object after processing is processed to rear broadcasting again.
Further, in embodiments of the present invention, any one virtual machine in server also can be carried out following flow process: receive the cancellation request of the cancellation broadcast destination object of connected terminal transmission, and after receiving cancellation request, other virtual machines in announcement server, for example by virtual management unit, notify, the terminal connecting to correspondence sends and disconnects the disconnection message being connected with any one virtual machine, to indicate counterpart terminal to disconnect with any one virtual machine after receiving disconnection message.
Below in conjunction with following embodiment, the above-mentioned destination object broadcasting method based on Intel Virtualization Technology is elaborated:
