Detailed description of the invention
In the present invention, so-called application can identify traditional application, i.e. in order to provide a user with required merit
Can and the application program that performs.This function includes text-processing, spreadsheet calculations, data base and management, image and figure
Process/generation/the management etc. of data.But, term application can also identify the mirror image of virtual machine to be understood to.Virtual machine is
At the upper software assembly providing a virtual processing entities of another entity (i.e. physical machine).Such as, virtual machine can be to adopt
With virtual Windows (TM) computer of actual motion on the computer of operating system based on Linux.But, at virtual machine
And run virtual machine processing unit between operating system can be the most different from each other.In any case, the feature of virtual machine
Be: it provides a package implementation for performing application to one or more users, wherein, the execution of application and because of
The operation of this virtual machine does not disturb other virtual machines operated on same treatment unit (at least in certain given restriction
Under).
In the present invention, processing unit is appreciated that for processing data and/or the one of communication in data center
Individual unit.Aforementioned so-called blade server may be constructed a this processing unit.But, processing unit can also is that independence
PC or server, these independent PC multiple or server are arranged to interconnected amongst one another to form data center.Can be at least by friendship
Level of changing planes is to use described interconnection, but generally switch-level is arranged corresponding to the physics of multiple processing units, i.e. district, row, machine
Frame etc..But processing unit can also by its each ability be limited to data forward, route and/or exchange.And hence it is also possible to will
Processing unit is interpreted as itself not running switch or the router entity of mirror image, but ought run application on a processing unit
Time, application may be constructed router/switch entity.
As explained, data center uses at least one switch-level, and it can reflect the thing of multiple processing unit
Reason is arranged.If be such as arranged in frame by processing unit, and then frame is arranged as row, and plurality of this row is constituted
, at least 3 this switch-level will be there are, such as by district's switch-level, row switch-level and frame switch-level in so-called district
Represent.Between two exchange/route entities of different switch-level, there is at least one connection for data communication.
Connection between 2 differences or 2 this entities of neighboring switch level can be partially shown as the sub-road of so-called network
Footpath, wherein, is defined as so-called network path terminating at a particular processor unit in multiple processing units.
In other words, network path is the possible path of the data going into or from particular processor unit for being scheduled.Net
Network path can be at the other end at another processing unit or at certain Central Access Point (such as, preceding gateway entity) place knot
Bundle.It is thus possible to define the other end of network path with desired data stream as requested.Such as, if will by from go
Route to such as the Internet toward the data of respective handling unit, can between respective handling unit and certain senior access point shape
Become network path.But, network path can also be maintained in a data center well, such as, do not exist together connection 2
During reason unit.If be such as distributed an application between some processing units, or when an application processes with operating in another
When Another Application on unit is mutual, the most this data stream can become essential.Example can be to process list as first
In unit first applies the web server run and as the second video stream server processing upper second application operation: two
Server application can part be alternately: web server utilizes video stream server to provide video flowing based on web to answer
With.
In the arranging of above-mentioned some switch-level, it is usually present one of tree-like path structure, i.e. a switch-level
Switch/router entity receives and sends data with an entity of higher switch-level, otherwise, exist from an exchange
Machine/router entity launches (fanout) some connections to the entity of lower switch-level.So, as also more comprehensively solved below
Release, the selection launching one of possibility is defined the network path leading to particular processor unit by each switch-level.
According to each aspect of the present invention, when adding application/image instance to data center, can allow to consider in data
The networked capabilities of the heart.Specifically, it may be considered that the current traffic load of each several part of data center and local and interim available
Networking capacity.This load distribution that allows preferably to network in data center, and it can avoid using data center to provide
Application and service time may cause the bottleneck situations of bad Consumer's Experience.
Additionally, each aspect of the present invention also allows for reserving (soft) of capacity in whole data center, thus with generally
Comparing of will allowing of the scheme of doing one's best, it is possible to SLA (SLA) is provided in more-controlled fashion.With do not have
The data center of this probability compares, and this can provide some advantages, wherein it is possible to very conservative and careful mode come to
Go out SLA and ensure (if any).
Fig. 2 and 4 shows the schematic diagram of data center according to an embodiment of the invention.Multiple processing units 10 are via extremely
A few switch-level 200 is coupled to gateway entity 30.As already described above, switch-level 200 can actually include
Corresponding more than one switch-level (district's level, row level, chassis level etc.) is set with the actual physics of processing unit 10.Permissible
Switch-level is represented, such as district's switch 21, row switch 22 and frame switch 23 by respective switch entity.
According to the present embodiment, it is provided that the allocation entity 50 in data center 1, it is from gateway entity 30, one or more
Switch-level 200 and processing unit 10 receive data and/or information.By received data, allocation entity 50 can be received
Collect the information relevant to the all-network path 40 that gateway entity 30 is connected to each processing entities 10.More specifically, distribution
Actual, prediction or scheduling the network that entity 50 can be collected between gateway entity 30 and each processing unit 10 is born
Carry relevant information.Described information can relate to current and/or given interval and/or time in the future point.In other words, distribution is real
Body 50 is configured to acquisition approach network load information, and the instruction of this path network load information leads to multiple processing unit 10 extremely
The offered load of at least part of network path.
Additionally, allocation entity 50 is configured to receive for answering to the distribution of one of multiple processing units 10 of data center 1
Application distribution request 500.Application distribution request 500 includes so-called application network load information, application network load letter
Cease in terms of the required offered load required to correctly operate and/or the required offered load caused by application to multiple
The application of a processing unit distribution in processing unit characterizes.Ensureing service quality (QoS) or can also specify
Big response time aspect defines described correct operation.
Additionally, described application distribution request or described application network load information can include that so-called application network loads
Profile, this application network load profiles specifies the required offered load at aspects such as event, particular point in time or time intervals.This
Sample, allocation entity 50 can become the application-specific knowing requested distribution and requires on particular point in time or cause how many networks
Load.
Therefore, allocation entity 50 can select particular processor unit 10 ', and this particular processor unit 10 ' is via satisfied application
One particular network path 40 ' of the requirement that network load information is illustrated is coupled to gateway entity 30.Such as, distribute to many
The distribution of one of individual processing unit 10 can be the video stream server of a large amount of offered load of requirement, because the video data volume is usual
The biggest.Know the real network requirement of this application, allocation entity 50 can select processing unit 10 ' to distribute application because its
Corresponding network path 40 ' can process currently, offered load in the future or required by special time in the future and time interval.
In other words, allocation entity 50 is introduced as new node (that is, business aware applications/mirror image allotter), its
Allow to find in data center application/mirror image is suitably distributed.In doing so, this node is collected and in data center
All networked link on the relevant data of life-span networking load situation.Use router and the traffic measurement interface of switch
Collect this information.If needing to distribute new application/mirror image, allocation entity 50 can perform search pattern, this search pattern
External interconnections node (gateway entity 50) in data center starts, and by choosing the path with minimum networking load, logical
The classification crossing networked node/switch is carried out to blade server (in the example shown, processing unit 10 ').
So, load consciousness management level are also introduced.This layer by the virtual image of data center's structure (thus, in data
The model of the heart) preserve together with instantaneous networking load situation.Additionally, the application/mirror image distributed is with corresponding application network
The networking load profiles of load information or correspondence.This is the description of load request of networking application.When dividing in data center
When joining application, load consciousness management level are that this application reserved networking virtually is born according to load profiles by data center all the time
Carry.If business consciousness mirror image allotter performs its search pattern to virtual data center model rather than real data center,
In order to be found for the optimal location of this application, i.e. processing unit 10 ', can be by the networking load profiles according to other mirror images
Other mirror image is reserved and potential load needs are taken into account.
It is said that in general, no matter data center distributes the networking aspect of the decision of application how, it is of course possible to exist permissible
Affect a lot of other standards of this decision.Entity and method that the present invention proposes provide contribution to overall decision process.
Referring now to Fig. 3 and 4, allocation entity 50 has the friendship led in the classification of data center 1 and tree network structure
Change planes/router 21,22,23 and the interface of processing unit 10.Additionally, allocation entity 50 has leads to data center management system
The interface 66 of 64.By this interface 66, allocation entity 50 can receive can distribute new opplication for search in data center 1
The order of position.The result of this search is transmitted back to data center management, itself so application/mirror image can be distributed accordingly.
In order to obtain the information of requirement about application, allocation entity 50 have lead to application and or mirror image warehouse (i.e.,
Data storage 600) interface 65, application or mirrored storage are in this warehouse or described in this warehouse.Interface 65 can be by
Application/mirror image Administration API (application programming interface) is constituted.Except the information (data relevant to this application being commonly stored
Code, application data and storehouse 71 in memorizer 61) outside, introduce application network load information 72, itself and application/mirror image phase
Association, to provide and to require relevant additional information, specifically, about the additional information of offered load.Described information 72 is permissible
It is stored in the data storage 62 of separation, or application data 71 and information 72 can be stored in a single common data and deposit
In reservoir 600.
The source of information is positioned in the availability of the interface 67 leading to data center network node 63, and this interface 67 allows to fetch
Relevant to all nodes and network link thereof (switch 21,22,23, gateway entity 30 and the processing unit 10 that i.e. relate to)
Current live network load situation.Therefore, by least some of node and link couples to allocation entity 50, to provide this
Information (dotted line in Tu2 &4).
In one embodiment, allocation entity 50 can ask node and the link currently considering with it/observing on one's own initiative
The relevant prompting message of load situation, or in another embodiment, it can be regularly to the poll load of whole data center 1
Information, and store this information to be used in searching algorithm.In another embodiment, can at the network node of data center (i.e.
The switch 21,22,23 related to) place's registration allocation entity 50, to receive the rule renewal relevant to network load information.
Furthermore, it is possible to these concepts fetching and processing load situation are combined, and can differently process in data
The different piece of the heart 1.
When new opplication should be added to data center 1 or adds the virtual image being mounted with application on it, allocation entity
50 participate in make decision: should distribute application/mirror image in data center 1.It finds has the highest idle connection in data center 1
Network capacity amount, and specifically, on the whole network path 40 ' of outside (i.e. gateway entity 30), there is the free time from processing unit 10
And the suitable treatments unit 10 of suitable capacity.The order performing this search manages 64 typically from data center, and to number
Result is reported back to according to centre management 64.This allows data center management system 64 when distributing the new example of application/mirror image by net
Network load is taken into account.
As has already been mentioned above, application/mirror image can also be with describing the profile that its networking load needs.A reality
Execute in example, can the such as individual files 72 in the warehouse (that is, data storage 62) of this load profiles store this
Load profiles.In this case, suitable profile is individually selected for each application/mirror image.In another embodiment, can be by
Application network load information is together with application/mirrored storage, or is even stored in the district of image file or description of image.
The profile of application network load information can comprise such as by the required minimum bandwidth being less than all the time or maximum belt
Wide information.But, this profile can also comprise the information relevant to conditionality or timeliness bandwidth feature (figure).Example
As, single bandwidth requirement can be provided for over skies different in different time or a week in a day.Allocation entity 50 can
To use this load profiles to determine, network link to be selected is if appropriate for supporting to be assumed to be in data center 1 to be deployed in
Being required of application/mirror image.Can expand to described application network load profiles also to comprise and being not related to of application/mirror image
The requirement that other aspects of networking are relevant.Such as, can come together designated treatment capacity requirement with networking requirement herein.
Referring now to Fig. 5 and 6, allocation entity 50 may be provided for data center's load controller 51.Data center
Load controller 51 establishes intermediate layer in the measurement that data center network loads.Data center's load controller 51 can be by
The map of data center topology stores together with the feature of present load situation.For data center each physical node and
Each link in data center's node, data center's load controller preserves the information that load situation of networking to it is relevant.With
Sample ground, described node can be made up of switch 21,22,23, entity 30 and/or unit 10.Described link may be constructed
State subpath.So, data center's load controller 51 safeguards the abstract mirror image of real data central loading situation.Taking of information
Return and the renewal continuously of load characteristic can be carried out in the way of being similar to describe together with other embodiments of the present invention.
Along with this intermediate layer is on appropriate position, allocation entity 50 the most directly will receive load from real data Centroid
Feature, but receive, from data center's load controller 51, the load characteristic obtained its abstract data center map safeguarded.
Except this change in finding the algorithm of position of new opplication/mirror image, other can keep identical.
This embodiment abstract mirror image based on data center rather than data center itself.Based on data center 1 its is taken out
As mirror image, data center's load controller 51 can perform the reserved of network capacity for each node and link.Therefore, number
Can receive or obtain path network according to central loading controller 51 and reserve information.Note that final deployment in data center 1
Application example, and the network path 40 ' found for this application example to its notice.Once deploy the example, and along quilt
Select in all virtual data center nodes on the path 40 ' for providing the Internet services to this application example and virtual data
Storing this offered load profile at heart link, data center's load controller 501 accesses the respective application offered load letter of application
Shelves (or general, application network load information).
If allocation entity 50 is new application example searching position, then the load presented for each node and link
Feature can be life-span (currently) load, or it can be based in data center's load controller 50 load profiles of storage
The potential load that the accumulation of definition requires.In addition it is possible to use the combination that live load characteristic and accumulation require.
As such, it is possible to reach the soft reservation of network capacity, because when distributing new opplication, the application example that will be deployed
Required capacity is taken into account.Although instruction is left capacity by present load situation, but for new deployment, can refuse
There is the path 40 of the high potential demand relevant to networking.Data center's load controller 51 is known and is serviced by this path
Application there is potential high demand.It can thus be avoided bottleneck in the future.
Owing to offered load profile can provide such as in different time and the complex characteristic of distinguishing load request on the date,
Therefore when determining the load whether specific node or link can obtain Another Application, it is also possible to this point is taken into account.No
Only can mate current requirement, it is also possible to coupling requirement in the future.Need by data center's management to data center's load control
Device 51 processed notifies that all of mirror image is disposed and removes.If removed or Mobile solution example, need to remove or rearrange and refer to
The path of the offered load profile of group corresponding storage together.
Fig. 7 shows the internal schematic diagram arranged of allocation entity according to another embodiment of the present invention.This allocation entity
50 include processor 501 and memorizer 502.Processor performs the code in memorizer 502 as unit 503 storage.Thus,
Can be realized or perform appointing of any feature as combined the entity described by embodiments of the invention or method by unit 503
What step, wherein, is performed its respective code by processor 501.
Fig. 8 A shows the schematic flow diagram of the embodiment of the method for the present invention.Therefore, in step sl, receive for number
Application distribution request according to a processing unit distribution application in multiple processing units at center.Application allocation request packet includes should
Use network load information.Additionally, in step s 2, acquisition approach network load information, the instruction of this path network negative information is led to
The offered load of at least one of network path in multiple processing units.Finally, in step s3, based on application network
Load information and path network load information, select processing unit to distribute application from multiple processing units.
Fig. 8 B shows the schematic flow diagram of the other method embodiment of the present invention.This embodiment describes in data
Search for the possible method of suitable processing unit for application-specific to be distributed in the minds of in.According to this embodiment, first
In step S11, search for suitable processing unit and start at the gateway entity of data center.Then, in step s 12, distribution
Entity checks the load situation relevant to all paths to subsequent node/router/switch.Based on this situation, in step
In S15, allocation entity is the most NA, to the subsequent node with the highest idle capacity before selecting in this search procedure
The link (subpath) of (that is, the switch of next one classification levels).
If in S13, can not find in the node/router/switch of current check and there is sufficient idle networking appearance
The link of amount, then the network node before search returns and step S12 of this algorithm.If owing to there is not more high-grade rank
Network node/router/switch before and make this impossible, then search for unsuccessfully and can not distribute in data center
This application (S14).If the subsequent node after selected link is router/switch equally, algorithm continues in step s 12
Continuous.If but the subsequent node after selected link is processing unit, in step S17, checks whether this unit meets want
Being required of the application/mirror image of distribution.This networking load situation being possible not only to check processing unit, it is also possible at such as inciting somebody to action
Reason load or memorizer utilization rate are taken into account.Required, then in step if the processing unit found in step S17 meets
Rapid S18 manages in this place and on unit 18, distributes/dispose this application.
If but the processing unit found in step S17 is unsatisfactory for being required, the network before search returns saves
Point and step S12 of this algorithm.If owing to there is no network node/router/switch before and make this impossible, then
Search for unsuccessfully and this application/mirror image (same, S14) can not be distributed in data center.
Above-mentioned algorithm can be to have the application/mirror image of high networking requirement to find external network (such as, public internet)
Suitably distribution.The algorithm of amendment can be provided for the application/mirror for there being high networking requirement to other parts of data center
