Abstract

The invention discloses a method for copying content in a desktop cloud system external device room. The method includes the steps that a storage address of data copy is judged; if the storage address is judged to be at a terminal, the terminal completes the data copy process through the calculating capacity of a terminal device, and the data copy operation does not need to be performed through a long-distance virtual machine. The method can reduce data copy time delay. Due to the fact the whole copy process is completed in the local place of the terminal device, participation of the long-distance virtual machine is not needed, the network communication process for transmitting data to the long-distance virtual machine and the network communication processor for transmitting the data back to the terminal device by the long-distance virtual machine can be eliminated, and meanwhile time delay caused by the two network communication processes can be eliminated. The method can further improve reliability of data copy and completely eliminate data transmission failure and other influences caused by network instability due to the fact that the network communication processes are eliminated.

Because the path between terminal equipment and remote virtual machine need to pass through network, so during the universal serial bus device on access terminal, need certain network capacity, so, in some basic operations, during such as copied files, not only need to consider the time delay that the literacy of universal serial bus device literacy and remote virtual machine is brought, also to consider the time delay that data are brought in transmission over networks, the extra time delay that this desktop cloud system is brought, unavoidable in the ordinary course of things, but at some in particular cases, but can reduce or even eliminate by optimizing, that is exactly that two universal serial bus devices on same terminal are when copying file mutually.

Referring to Fig. 1, in the situation that without optimizing, if another external equipment on from an external equipment copied files on terminal to this terminal, the network transmission protocol of mentioning before needing arrives data the dummy general serial bus interface of remote virtual machine by Internet Transmission, by the remote virtual machine computing capability, process, then by remote virtual machine by result from another dummy general serial bus interface by Internet Transmission to terminal equipment.There is much additional consumption obviously in this processing mode, and these consumption are all avoidable.

Because terminal equipment itself possesses certain computing capability, and these computing capabilitys fully enough are used for copied files, so optimal way that can be achieved as follows: if a plurality of memory devices on same terminal equipment are copied file mutually, selection gets around the step of Internet Transmission, by terminal equipment copy procedure by oneself, data are directly completed to copy procedure on terminal equipment.Like this, not only removed the time delay that twice Internet Transmission bring of having a try from, improved performance, the factors such as network failure of also having avoided Internet Transmission to bring, improved the reliability of data copies.

Summary of the invention

The method that the purpose of this invention is to provide reproducting content between a kind of desktop cloud system external equipment, solve defect and deficiency that prior art exists.

The invention provides the method for reproducting content between a kind of desktop cloud system external equipment, the remote virtual machine that described desktop cloud system comprises some terminals, is arranged on the some external equipments on described terminal and is connected with described terminal network, described external equipment connects described terminal by universal serial bus device, when described universal serial bus device carries out data copy operation, memory address to described data copy judges, if described memory address, in described terminal, completes described data copy procedure by described terminal by its equipment computing capability.

Described method judges described memory address by following steps: described terminal is when connecting described remote virtual machine by the network transmission protocol, generate corresponding information storage addresses table, preserve physical equipment position corresponding to described memory address, when described universal serial bus device carries out data copy operation, judge that physical equipment corresponding to its memory address is at described remote virtual machine or on described terminal.

Whenever there being new external universal serial bus device to be linked into described terminal, or original external universal serial bus device and described terminal are upgraded described information storage addresses table, the change of recording described information storage addresses table while disconnecting.

Described method also comprises: when described universal serial bus device carries out data copy operation, memory address to described data copy judges, if described memory address is at described remote virtual machine, by described terminal, transfer data to described remote virtual machine and process, described remote virtual machine completes described data copy procedure by its equipment computing capability.

The present invention has the determining step to the memory address of data copy, if the judgement memory address completes described data copy procedure by described terminal by its equipment computing capability, and needn't carry out data copy operation by remote virtual machine in described terminal.The present invention can reduce data copy time delay, because whole copies data process is all to complete in terminal equipment this locality, do not need the participation of remote virtual machine, can remove from and transfer data to remote virtual machine, and by remote virtual machine, transfer of data is returned to two sections network service processes of terminal equipment, also removed this two sections time delays that the network service process is brought simultaneously from.The present invention can also increase the reliability of data copy, due to the process of having removed network service from, has eliminated the impacts such as data transmission fails that unstable networks is brought fully.
