Embodiment
Below will at length narrate embodiments of the invention with reference to accompanying drawing.In following being described in detail, function is according to classification and narrations such as server, client terminals, but whenever necessary, function can be implemented by another device.
Fig. 1 is the block scheme that whole Internet service system is provided, and this system uses the disposal system of keyword according to an embodiment of the invention.
As shown in Figure 1; In individual counter (PC) system 10 that each dwelling house is installed and company/agent calculator system 12 via in predetermined mechanism; The Local Area Network of for example setting up in school or the company is through accesses network, for example; The leased line 28 visit road router threes 0 of public switch telephone network (PSTN)/Integrated Service Digital Network(ISDN) (ISDN) 22, digital subscriber line (xDSL) 24, wireless network 26 or similar Hybrid Fiber Coax (HFC) cable are connected to the internet.This router three 0 is through keyword disposal system 40 access internet service providers (ISP) 50.
As shown in Figure 1, keyword disposal system 40 is the separate payment between this router three 0 and this ISP50, but can also be included among this router three 0 or this ISP50.Moreover this keyword disposal system 40 is mainly used on network and receives and to handle from this router three 0 or the hub data via Network Transmission, in these hub data via internet transmission and gathering.Therefore, this keyword disposal system 40 can be installed in any place that can reach such purpose.
Below will be described in detail the function of this keyword disposal system 40.This keyword disposal system 40 can use mirror method or Proxy Method to receive the data through Network Transmission.
(1) mirror method
This mirror method is in the network switching, and for example, layer 7 (L7) switch copy data when waiting, and use this network throughput to make the method for observation or the like.Here, particular port has been used in this network switching.When the bag mirror image used the switch function to carry out, many loads possibly be placed on this switch, and thereby can use Network Taps.
According to this mirror method, when original data are transmitted with classic method, copy data is handled.Thereby, the trouble that might avoid the use of the internet with in addition avoid the delay handled when the generation problem in processing procedure.
(2) Proxy Method
This Proxy Method is the additional agent equipment of in the middle of network, installing, and by this, only carries out the method for next procedure during through this acting server when data.Because only after data are fully by proxy server processes, just can carry out next procedure, this can guarantee the processing of data.
According to present embodiment, the networked information retrieval tools monitoring sees through the network data of this mirror method or the transmission of this Proxy Method.Yet, when lot of data need be monitored, can in the keyword disposal system 40 of handling these data, sizable load be arranged.In this case, whole network is slowed down, or the treatment effect of this keyword disposal system 40 is reduced.Therefore, preferably only distinguish and handle data necessary.
Can at first analyze, whether to come, to use whether the communication protocol of what kind, these data are that pending data are distinguished in a kind of response or a kind of inquiry or the like from the particular server transmission according to these data to the various titles that append to data.Secondly, can confirm whether these data are keyword.Moreover, might confirm directly whether these data are keywords under the situation that does not have this first differentiated treatment, and also can carry out various improvement.
Fig. 2 is the block scheme of the disposal system of keyword according to an embodiment of the invention, and Fig. 3 is the block scheme of the disposal system of the keyword of Fig. 2 according to an embodiment of the invention.
Client terminal 100 is connected with keyword disposal system 40 on network path.Keyword disposal system 40 is connected with domain name system (DNS) and native language internet address (NLIA) server 200 respectively through internet 60.In case of necessity, these keyword disposal system 40 addressable search server 300.
According to the formation of this keyword disposal system 40, this keyword disposal system 40 comprises definite device 44 of inquiry and database 46, and can further comprise networked information retrieval tools 42.
Use before network data handles the method for keyword being described in detail, will narrate network data layer and each title.
Protocol groups for example TCP (TCP/IP) is made up of multi-layer protocol, and shown in following table 1, TCP/IP forms by four layers usually.
Table 1
In application layer, carry out the detailed functions that is used for practical communication.When by user data that application layer produced the time, the data of network layer and link layer, each layer are joined in the user data through transport layer.As a result, constitute complete communication data, i.e. ethernet frame (seeing table 2).
Table 2
The Ethernet title that constitutes in this manner comprises media interviews control (MAC) address, and this MAC Address is the hardware address of purpose and source Local Area Network card.The IP title comprises the IP address, protocol type in purpose and source etc.TCP (UDP (UDP)) title is included in the information on the COM1 of corresponding service.
Application data is the practical communication data and comprises the kind of representing this communication data and the header area of characteristic.
Well-known port one to 1023; For example; HTTP(Hypertext Transport Protocol): 80, FTP (FTP): 23, telecommunicatio network: 21, pop3 post office protocol version 3 POP3 (POP3): 110 or the like, mainly as the serve port of TCP or UDP communication, rather than COM1 arbitrarily.Thereby, when TCP (UDP) title being analyzed when obtaining serve port information, need not analyze under the situation of whole communication data, might use well-known port come the kind of primary data.For example, when the destination slogan of TCP title was 53, corresponding data were the DNS inquiry.On the other hand, when the destination slogan of TCP title was 80, corresponding data were the HTTP inquiry.
Whether below will be described in detail definite text string of importing is the keyword query with transport network information.
< the unified resource information (URI) according to the title of HTTP inquiry is confirmed >
Inquiry confirms that device 44 receives the HTTP inquiry among the network information of coming from client terminal 100 transmission.Then; This inquiry confirms whether the input storage unit identifier that device 44 is confirmed to be stored among the identifier database 46a exists in the URI of the title that this HTTP inquires about, and confirms that this HTTP inquiry is about the keyword query in the address window that is input to the client network browser.
Below will narrate input storage unit identifier.When the text string except that common URL inquiry, for example keyword for example is input to, and during the address window of Internet Explorer 7.0, text string is transformed into inquiry and is transferred to search server.Here, the territory that the text string in the address window that is input to this web browser is transformed into inquiry and transmits the search server 300 of this inquiry set for the search window that will be input to webpage in the search word be transformed into search server 300 identical of inquiring about and transmitting this inquiry.
More particularly; Work as keyword; For example "
"; When being input to the address window of InternetExplorer 7.0, it is transformed into inquiry
Http:// search.live.com/results.aspx? Q=%ED%8A%B9%ED%97%88%EC%B2%AD&mkt=en-us%FORM=OPNSCH " and handle that (the IP address of search.live.com is for " 211.196.154.198 ".
Moreover; Even when identical keyword "
" when being input to search window, it is transformed into similar inquiry
" http://search.live.com/results.aspx? q=%ED%8A%B9%ED%97%88%EC%B2%AD&mkt=en-US%form=QBRE " and handle.Under both of these case, all transmit identical host information " http://search.live.com ".
The inquiry of two kinds of situation is all very similar each other but have different piece, and promptly " OPNSCH " reaches " QBRE ".Thereby this part saves as the identifier in this identifier database 46a, and this inquiry confirms whether the input storage unit identifier that device 44 is confirmed to be stored among the identifier database 46a exists in the URI of the title that this HTTP inquires about.When the input storage unit identifier in being stored in identifier database 46a existed in the URI of the title of this HTTP inquiry, this inquiry confirmed that device 44 definite these HTTP inquiries are about the keyword query in the address window that is input to the client network browser.
Therefore, the input storage unit identifier that is stored among the identifier database 46a is a text string, uses it can confirm whether keyword is to be input to the address window of client network browser or the text string of search window.This input storage unit identifier can be different in response to search engine, and selected in advance to constitute this identifier database 46a by system constructing person or keeper.
Simultaneously, URI, host information etc. are also included within the title of HTTP inquiry.Moreover; Data, for example " accept (Accept) ", " coding (Encoding) ", " main frame (Host) " etc. all are recorded in after the information with the form of " method (Method) (space (space)) URI (space (space)) version (Version) " with the form of " field name: information ".Thereby, can be with the value of URI joint difference for two spaces between the HTTP title.In addition, because host information joint with " main frame (HOST): ... " form, the part of the detectable beginning with " main frame (HOST): " is distinguished this host information joint.Here, " method (Method) " is information, for example " GET ", " POST " or the like, and " version (Version) " be information, for example " HTTP/1.1 " or the like.Table 3 shows the example of HTTP title.
Table 3
| HTTP ¨ GET/results.aspx? Q=%EC%B7%A8%EB%AF%B8&mkt=en-us&FORM=OPNSCH r Request Method:GET Request URI:/results.aspx? Q=%EC%B7%A8%EB%AF%B8&mkt=en-us&FORM=OPNSCH Request Version:HTTP/1.1 Accept:image/gif; Image/x-xbitmap; Image/jpeg; Image/pjpeg; Application/x-shockwave-flash; Applid r r Accept-Encoding:gzip, r User-Agent:Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322) r r r Cookie:SFORM=OPNSCH; AFORM=OPNSCH; SRCHUID=V=1&GUID=F5B7BD152490489FAC4167D19A0833B3; SRCHUSR=AU-r |
For example, in the HTTP of table 3 title data, URI be "/results.aspx? q=%EC%B7%A8%EB%AF&B8&mkt=en-us&FORM=OPNSH " and host information be " search.live.com ".
< URI according to the title of HTTP inquiry confirms >
Store information at least one main frame of device 44 in host information database 46c is confirmed in this inquiry.This inquiry confirms that device 44 receives the HTTP inquiry and confirms whether the host information that is included in this HTTP inquiry is stored among this host information database 46c among the network information of coming from the client terminal transmission.When the host information in being included in this HTTP inquiry was stored among this host information database 46c, this inquiry confirmed that device 44 definite these HTTP inquiries are about the keyword query in the address window that is input to the client network browser.
For example; In Internet Explorer 6, except that common DNS form, keyword is transformed into the inquiry that comprises " auto.search.msn.com "; And except that address window, the value that is input in the search window is used another inquiry that comprises " search.msn.com ".Thereby, when " auto.search.msn.com " is included in the host information, can confirm that keyword is imported in the address window.In this case, the keyword that only is input in the address window of client network browser can change the inquiry that comprises " auto.search.com " into, thereby does not need identifier server.The information of this host information database 46c also is to be made up of system constructing person or keeper.
In this host information database 46c, store the expression particular server, for example " auto.search.msn.com ", host information.
Above chat is into according to definite method of the URI of the title of HTTP inquiry and according to definite method of the host information of the title of HTTP inquiry, but might use URI and host information.In other words, this identifier database 46a can store at least one input storage unit identifier and also can store the host information with this input storage unit identifier match.More particularly, at first this inquiry confirms whether the host information of the title of device 44 definite HTTP inquiries is stored among this identifier database 46a.Secondly when this inquiry confirms that the host information of the title that device 44 is confirmed to inquire about as HTTP is confirmed to be stored among this identifier database 46a, stored and whether in this URI, exist with input storage unit identifier that host information matees.When this input storage unit identifier existed in this URI, this inquiry confirmed that device 44 definite these HTTP inquiries are about being input to the keyword query in the client network browser.
This keyword disposal system 40 can have networked information retrieval tools 42.When the destination interface data adapting of the title of the host information that comes from client terminal transmission when HTTP inquires about, this networked information retrieval tools 42 can confirm that this network information is the HTTP inquiry and transmits this network information to the definite device 44 of this inquiry.
