Abstract
The invention provides a virtual platform real-time and non-real-time processing environment data exchange method, which comprises the following steps: a step of issuing a theme: when the virtual machine initializes the virtual peripheral, the virtual peripheral is used as a theme to be issued; the QoS policies of the different types of virtual peripherals are different; and a topic subscription step: one virtual machine establishes a virtual communication link with other virtual machines by subscribing to a theme; a data distribution step: and the virtual machine which establishes the virtual communication link distributes data according to the QoS strategy to complete the data exchange process.
Description
Technical field
The present invention relates to field of data exchange, in particular it relates to virtual platform is handed over Non real-time processing environmental data in real time
Change method.
Background technology
With the lifting of hardware platform performance, by means of Intel Virtualization Technology, real-time system and non real-time system and be stored in
One hardware platform, real-time processing environment become a kind of trend with the fusion of Non real-time processing environment.But real-time system with non real-time
Carrying out data exchange between system becomes technological difficulties of both fusions：
1st, hardware data means of communication is a lot (including shared drive, RapidIO, DMA etc.), and virtual platform should be upper strata
Virtual machine provides abstract hardware, while need the means of communication for selecting optimum performance in practical communication as far as possible again, to make up
The performance loss that level of abstraction brings, it is flexible enough that this is accomplished by data exchange mechanism；And existing data exchange mechanism often with
Specific communications means are bound, and lack flexibility；
2nd, the communication between virtual machine, according to the position that virtual machine is distributed, can be divided into same Platform communication and different platform is logical
Two kinds of situations of letter.For same Platform communication, generally by means of shared drive, DMA (Direct Memory Access, directly in
Deposit access) etc. mode complete, and different platform communication, then may by means of different peripheral, such as Ethernet, serial ports,
RapidIO etc..And existing data exchange mechanism, stronger with traffic scene coupling, it is unfavorable for extending.
3rd, existing virtual platform data exchange mechanism, exchange both sides are too strong on the coupling in time, space, particularly
When real-time system carries out data exchange with non real-time system, the real-time of real-time system can be weakened, or reduce data exchange
Reliability and robustness.
Content of the invention
For defect of the prior art, it is an object of the invention to provide a kind of virtual platform in real time with Non real-time processing ring
Border method for interchanging data.
According to the present invention provide a kind of virtual platform in real time with Non real-time processing environmental data exchange method, including：
Issuing subject step：During virtual machine initialization of virtual peripheral hardware, the virtual peripheral is issued as a theme；
Wherein, it is different between the qos policy of different types of virtual peripheral；
Topic of subscription step：One virtual machine passes through topic of subscription, to set up virtual communication link with other virtual machines；
Distribution data step：The virtual machine of virtual communication link has been set up, and data distribution has been carried out according to qos policy, complete
Into data exchange process.
Preferably, the theme includes：Microsoft Loopback Adapter theme, virtual serial port theme or virtual hard disk theme.
Preferably, the corresponding qos policy of type that is set up by virtual communication link between the virtual peripheral of communication is identical.
Preferably, the distribution data step, including：
Issue data step：Sender packs the data to the message for setting form, is put into the buffering area of recipient, and leads to
Know subscription distribution service.
Transmission data step：Subscribing to distribution service carries out data distribution according to qos policy, places data into the slow of recipient
Area is rushed, and notifies recipient；
Receiving data step：Digital independent is processed from data buffer zone by recipient to the address space of oneself.
Compared with prior art, the present invention has following beneficial effect：
The present invention is built by distribution model and supporting quality of service policy (QoS, Quality of Service) is subscribed to
Founding a kind of real-time system of virtual platform and non real-time system carries out more flexible, the extendible mechanism of data exchange, and obtains
Desirable balance between real-time property and reliability；And by this mechanism, real-time processing environment with Non real-time processing
Environment can effectively reduce the impact to its own processing capability in real time when data exchange is carried out, while data exchange is real-time
Property and reliability, also at utmost can be guaranteed.
Description of the drawings
The detailed description that non-limiting example is made with reference to the following drawings by reading, the further feature of the present invention,
Objects and advantages will become more apparent upon：
Fig. 1 is virtual machine communication scheme.
Fig. 2 is virtual machine communication scheme.
Fig. 3 is data distribution flow chart.
Specific embodiment
With reference to specific embodiment, the present invention is described in detail.Following examples will be helpful to the technology of this area
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill to this area
For personnel, without departing from the inventive concept of the premise, some changes and improvements can also be made.These belong to the present invention
Protection domain.
The present invention with reference to DDS (Data Distribution Service, the Data distributing) specification of OMG, pass through
Data-centered publish/subscribe model, builds an abstract virtual platform data exchange space, all numbers to be exchanged
All it is present in this space according to object, and virtual machine node sets up abstract communication link then by publish/subscribe theme,
And data object interested is accessed by simple read-write operation.
Whole data exchange process can be divided into three parts：Issuing subject；Topic of subscription；Distribution data.
1st, issuing subject is described as follows.
When virtual machine initializes certain virtual peripheral, the virtual peripheral is issued as a theme.Dissimilar
Virtual peripheral, its qos policy is different.
(i) Microsoft Loopback Adapter theme example
(ii) virtual serial port theme example
(iii) virtual hard disk theme example
2nd, topic of subscription
Virtual machine node passes through to subscribe to certain theme, to set up virtual communication link with other virtual machine nodes.Qos policy
Must mate, could subscribe to successfully, namely the virtual peripheral of only same type could set up virtual communication link.
3rd, data are distributed
The virtual machine node of virtual communication link is set up, data distribution is carried out according to qos policy, data exchange is completed
Process.
I () issues data
Sender packs the data to the message of specific format, is put into the buffering area of recipient, and notifies to subscribe to distribution clothes
Business.
(ii) data are transmitted
Subscribing to distribution service carries out data distribution according to qos policy, places data into the buffering area of recipient, and notifies to connect
Debit.
(iii) receiving data
Digital independent is processed from data buffer zone by recipient to the address space of oneself.
Above the specific embodiment of the present invention is described.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make a variety of changes within the scope of the claims or change, this not shadow
Ring the flesh and blood of the present invention.In the case where not conflicting, feature in embodiments herein and embodiment can any phase
Mutually combine.
