A kind of method that corresponding time interval data is screened according to user's requestTechnical field
The present invention relates to a kind of data processing field, especially relate to a kind of screening according to user's request and correspond to time intervalThe method of data.
Background technology
Based in full flow backtracking analysis of network, due to odjective cause, stream packets only know that it starts and tiesThe bundle time, so when user wants the data inquiring about certain time interval, can only be the time interval of inquiry and stream packetsStart and end time takes common factor, if there is common factor, then illustrate that this stream packets is intended to the packet inquired about it should returnBack to user；If there is no common factor, user just should not returned to.But, how friendly inform that user inquired about whenBetween interval and be not exactly equal to the packet beginning and end time that it inquires, and the relation of two time intervals, just become oneThe problem that must solve.
Content of the invention
It is an object of the invention to：The problem existing for prior art, provides a kind of screening according to user's request to correspond toThe method of time interval data, what the existing screening technique of solution can not be friendly informs that the time interval that user is inquired about is simultaneously incompleteThe packet beginning and end time inquiring equal to it, and the relation of two time intervals.
The goal of the invention of the present invention is achieved through the following technical solutions：
A kind of method according to the corresponding time interval data of user's request screening is it is characterised in that the method comprising the steps of：
(1) receive user inquires about the request instruction of all flow datas in certain time interval；
(2) all flow datas are traveled through, if the time interval residing for flow data has common factor with the time interval of user's inquiry,Then calculate the relativeness of two time intervals, and be depicted as graph of a relation rear line in different colors and show.
As further technical scheme, the relativeness of two time intervals includes：Time interval residing for flow dataPart falls into, entirely falls in or covers the time interval of user's inquiry.
As further technical scheme, the method for drafting of described graph of a relation is as follows：
(1) one drafting graph region of setting, the centre in this region represents the time interval of user's inquiry with color A；
(2) time interval residing for flow data falls into part color B of time interval of user's inquiry and represents, do not fall withinPart color C of the time interval of user's inquiry represents.
As further technical scheme, the time interval residing for flow data is with the time interval that user inquires about using identicalRatio is drawn.
As further technical scheme, if the time interval residing for flow data exceedes drafting graph region, exceed partWith the instruction of little triangle.
Compared with prior art, the present invention is according to flow data beginning and ending time and user's query time, using different colours, directlySee the relativeness representing both understanding.
Brief description
Fig. 1 is the schematic flow sheet of the present invention；
Fig. 2 is the flow-time graph of a relation of the present invention.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
As shown in figure 1, the present invention provides a kind of method screening corresponding time interval data according to user's request, very friendlyUtilization time interval relation, the clear relation presenting two time intervals, directly perceived and succinct, the method includes walkingSuddenly：
(1) receive user inquires about the request instruction of all flow datas in certain time interval；
(2) all flow datas are traveled through, if the time interval residing for flow data has common factor with the time interval of user's inquiry,Then calculate the relativeness of two time intervals, and be depicted as graph of a relation rear line in different colors and show.
Wherein, the relativeness of two time intervals includes：Time interval part residing for flow data falls into, entirely falls inOr cover the time interval of user's inquiry.The method for drafting of graph of a relation is as follows：
(1) one drafting graph region of setting, the centre in this region represents the time interval of user's inquiry with color A；
(2) time interval residing for flow data falls into part color B of time interval of user's inquiry and represents, do not fall withinPart color C of the time interval of user's inquiry represents.The time interval that time interval residing for flow data is inquired about with userDrawn using same ratio.If the time interval residing for flow data exceedes drafting graph region, referred to little triangle beyond partShow.
The present invention provides a kind of specific embodiment of graph of a relation, as shown in Figure 2.In figure has 4 kinds of different states, and firstKind it is that far beyond the border that can draw and dwell time is intersected with query time segment part for the initial time of stream packets；Second is that the initial time of stream packets is just equal to the initial time of query range and dwell time is considerably beyond can paintThe border of system；The third is similar with the first, and except for the difference that initial time is in drawn border；4th kind is stream packetsIt is interval interior that beginning and ending time is completely contained in query time.In figure color 1 represents the beginning and ending time of data on flows bag, and the present embodiment is adoptedRepresented with Lycoperdon polymorphum Vitt, in figure color 2 represents the beginning and ending time of inquiry, the present embodiment is represented using black；In figure color 3 represents flowThe time portion that packet is intersected with query time, the present embodiment adopts translucent for color 1 display；The in figure little triangle of blackThe rising of 4 expression data on flows bags, only time are considerably beyond drawing area.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention it is noted that allAny modification, equivalent and improvement of being made within the spirit and principles in the present invention etc., should be included in the guarantor of the present inventionWithin the scope of shield.
