Huge and constant update.Extensive object data abundant can be obtained whithin a period of time.Simultaneously as monitoring
The quantity of equipment is more, precision, range and noise etc., thus within each period, it tends to obtain a large amount of of monitoring object
Data, and certain data distribution is all presented in data in this way.Therefore, clustering can be carried out to the data object, and
When carrying out the clustering of object under uncertain environment, the geometric distance of object data value itself cannot be only considered, it is also necessary to
Consider the uncertainty and influence of the data distribution to cluster of object.
Under uncertain environment, the data of object show certain distributivity, the uncertainty of object be also by pair
The probability distribution of image data is presented.Due in uncertain data stream the data distribution of object it is probability, thus, measure not
Need to consider the probability distribution of object when determining the similarity between object.For example, in hotel information analysis, it is desirable that each user
It is scored in all its bearings different hotels, for example service quality, food and drink quality, sanitary condition and price charge etc. are different
Angle.Each hotel can be scored by many users.User can be modeled as one based on use to the satisfaction in hotel
The uncertainty plant of family scoring.For a large amount of hotel's data and user's evaluation, need according to the satisfaction of user to hotel into
Row cluster.When clustering to these hotels, the similarity between comparison other cannot be only according to score value, it is also necessary to root
According to the distribution situation of score value.The high hotel of score should be low with score camera be distinguished, meanwhile, if the hotel Liang Ge
Divide equally, but the distribution of score is different, then should also have any different between them.According to probability density characteristics to uncertain data
During cluster, need to model the data distribution of object.Since uncertain data has a variety of probable values,
How to model and indicate the uncertainty and probability distribution of data, and improves the key of clustering result quality.
As analyzed above, in the application of hotel's data flow, object data often has higher-dimension characteristic.In higher dimensional space
In, the data of object show certain data distribution usually than sparse.Thus, when handling High Dimensional Data Streams, need
The distribution situation of statistical data example probabilistic value, to carry out compression and feature extraction to higher-dimension characteristic.Histogram as statistics and
The common method of description probability distribution needs to optimize the construction of histogram when handling high dimensional data.For continuous updating
Hyperspace is divided into multiple subspaces, passes through system by magnanimity high dimensional data in order to improve the computational efficiency of probability mass function
The probability distribution in different subspace is counted, and then efficiently extracts probability distribution information.
Based on above-mentioned thought, the design energy of the SDN exchanger of mission bit stream feature extraction of the invention and analysis submodule
It enough implements function such as or works as follows: is complete empty by inciting somebody to action to each example of uncertain data object dataset
Between be divided into multiple subspaces, to count the object data example in current sliding window mouth in the probabilistic information of different subspace,
For d Discrete numeric field data is tieed up, constructs one dDimension spaceR d ,R d =R 1 ×R 2 ×…×R d ,R i It indicatesR d The i-th dimension it is empty
Between component, it is assumed that by every one-dimensional spaceR i It is divided intop j A division,,
Then by discrete data spaceRIt is divided intoA hypercube space therefrom selects N number of subspace
The more intensive subspace of data distribution out, and then to optimize the construction of histogram.
When constructing histogram, the subspace for selecting data distribution more intensive, the Interesting subspace as histogram comes
Optimize histogram；When selecting the Interesting subspace of histogram, the probability distribution information of the data in every sub-spaces is analyzed, such as
Data distribution of the fruit in the subspace compared to be uniformly distributed want intensive when, then the subspace be Interesting subspace, that is, feel emerging
The hotel of interest.
Wherein, Interesting subspace is defined as the probability density put in the subspace and is greater than point of each dimension when being distribution
Number, whereinFor objecto k One group of data instanceu n In spaceThe quantity of middle distribution,n p It indicates respectively to tie up points purpose average value when object data is uniformly distributed,Expression is greater thann p Likelihood ratio user's specified thresholdτGreatly, thenIt is objecto k It is emerging
Interesting subspace, i.e., interested hotel.
Preferably, the SDN exchanger of the invention is all passes through same data path and carries out with inbound port out
Data are transmitted, and the moderator concentrated outside port there are one is determined time and the mode of some port of access switch by it.
This design is for make SDN exchanger advanced row buffering, this buffering before issuing data frame can
Data packet is forwarded in time at device port, and is unlikely to generate congestion.
Preferably, data packet is dropped in order to prevent, and SDN exchanger can choose the following two kinds setting: (1) port buffers
Design, the design distribute certain high-speed internal memory on the ethernet port of interchanger, to be used to the number that will be forwarded
It is buffered according to hardwood；(2) shared drive designs, and provides shared memory space, the forwarding and biography of data simultaneously for all of the port
It is defeated to require by forwarding decision, and forwarding decision is made by SDN switch, exchange opportunity passes through three-state content addressing
Memory technology inquires the flow table information of data, and determines subsequent whether distribute.
This system of the invention makes full use of the request number of times of supplier's opening and does not cause additionally to press to supplier
Power meets the screening of concurrent tasks, develops the flow controller for all suppliers of a set of unification, both can solve these and asked
Topic, and the upper offline of each supplier can be managed well.
This system of the invention has also been accurately controlled the pressure for each supplier, is guaranteeing to make full use of supply
Under the premise of the open request amount of quotient, the situation for largely requesting to cause task overstocked in the short time is shielded and in task amount
To the protection of relatively important request task when bigger than normal, it ensure that and the steady of supplier's pressure is exported and to request quality
