  However, in this WEB search system, the processing load on each WWW server (web server) and the congestion status of the route on the way are not considered, so the information of the WWW server presented as a search result can be browsed immediately. There is a problem that it cannot be determined whether there is any.

  For example, the concentration of accesses from many nodes to a specific content provider (web server) having certain information increases the response time of the web server, and the node user has a great deal of time to obtain the desired information. There may be inconveniences such as being forced to spend time.

  On the other hand, as a method for measuring the response time to the target WWW server (web server) when using the Internet, a method of measuring the response time using ICMP (Internet Control Message Protocol) is known.

  As a related technique, a technique for visually displaying the congestion status of a service when a predetermined service on the Internet is used from a specific node terminal is disclosed (Patent Document 1).

  Further, a technique for grasping the communication status in the network by newly providing a network device on the Internet (in the network) is disclosed (Patent Document 2).

Here, a case where the total search system 200 acquires information from the client node 110 will be described, but information sent from the client nodes 120 and 130 is also acquired and managed in the same manner.

  The control unit 230 includes a receiving unit 231 that receives information sent from the client node, a totaling unit 232 that stores the information sent from the client node in the response time DB 210 or the search DB 220 according to the information type, and the search DB 220. Search means 233 for performing a keyword search via the network, and transmission means 234 for returning information such as a search result list in response to a request from a client node.

The receiving unit 231 receives a search request (data) transmitted from each client node.
Here, based on the received search request data, the search means 233 performs a keyword search based on the information stored in the search database 220, and a WWW server having a web page or the like on which similar information is posted. List up.

The aggregation means 232 has a response time storage function for storing the response time of each WWW server included in the search request data in the response time database 210.
Here, in the response time database 210, a server-specific table 212 that associates the stored response time with the corresponding WWW server is generated.

The search means 233 has a search function for searching information such as a web page stored in the WWW server based on a preset keyword.
This search function may be configured to collect and store information such as web pages belonging to the WWW server in advance in the search DB 220, and to perform keyword search for the information stored in the search DB 220.

Further, the search means 233 has a similar information search function for searching for similar information for information determined to approximate a keyword based on a preset criterion.
Further, the search means 233 associates information collected by the search (hereinafter referred to as “search collection information”) with the WWW server to which the information belongs.
Here, the search means 233 refers to the WWW server-specific table 212a (FIG. 11) and refers to the response time of the WWW server to which each search collection information belongs, and belongs to the WWW server with a short response time. The order of the search collection information is rearranged so that the search collection information is preferentially listed at the top, and as a result, a search result list (hereinafter referred to as “WWW search”) sequentially placed from the search collection information belonging to the WWW server with a short response time A search result generation function for generating a “result list” is provided.

  As described above, in this embodiment, it is possible to acquire a search result of a WWW server that is aggregated from each client node and includes the response time of each communication path and the WWW server.

[Description of Operation of Embodiment]
Next, the operation of collecting the response time of the WWW server 410 in this embodiment will be described based on the flowcharts of FIGS. 3 and 4A and the sequence chart of FIG.

[Response time measurement]
First, the processing unit 119 of the client node 110 makes an inquiry about the operation state of the search unit 233 to the aggregation search apparatus 200 and determines whether or not the search function in the search unit 233 is operable (valid). (Step A101).

Here, when the search function of the search unit 233 is in an inoperable state (invalid state), the measurement unit 112 of the client node 110 measures the response time in the WWW server.
The search function in the search means 233 can be enabled or disabled by the user, but the connection to the WWW server with a slow response time can be made using the response time measurement result (measurement result) of the WWW server. When (access) is performed, the search function may be automatically enabled.

Next, in order to specify the WWW server (410 in this case) that measures the response time, the capture unit 114 of the processing unit 119 is set to the valid state.
Here, the capture unit 114 waits until a DNS request packet (DNS resolution request packet: FIG. 5) is transmitted from the client node 110 (step A102).
Note that this DNS request packet includes server information such as an IP address for identifying each WWW server (410, 420, or 430).

  Next, when a DNS request packet is sent from the WWW browser 111 (step A103), the capture unit 114 acquires the DNS request packet, and the WWW server information (indicating the WWW server 410) included in the DNS request packet. The WWW server 410 is determined to be a response time measurement target server, and the measurement unit 112 is notified. Thereby, the measuring means 112 becomes effective.

Here, for example, when a large number of WWW servers on the Internet are set as response time measurement targets, the response time measurement targets are duplicated, and the amount of data handled on the tabulation search apparatus 200 side may become enormous. Conceivable.
For this reason, in the present embodiment, only the access to the new WWW server is set as the response time measurement target, triggered by the transmission of the DNS request packet.
As a result, it is possible to reduce the amount of data handled by the tabulation search apparatus 200 and the occurrence of duplication of response time measurement processing.

  Note that the DNS request packet is held by the client node 110 for a certain period of time. Generally, the contents of the DNS request packet are cleared when the preset holding time ends or when the client node is turned on / off. Therefore, the response time can be measured with an appropriate frequency according to the usage frequency of the client node.

Next, when the WWW browser 111 accesses the WWW server 410, the WWW browser 111 first transmits a TCP session start request (TCP SYN: FIG. 5) to the WWW server 410.
At this time, the capture unit 114 captures (acquires) the corresponding packet of the TCP SYN, and the measurement unit 112 starts measuring the response time (step A104: response time measurement start).
Next, the WWW server 410 returns a TCP session start response (TCP ACK) to the TCP session start request (TCP SYN) (FIG. 5), and the WWW browser 111 receives a TCP session start response (TCP from the WWW server 410). ACK: FIG. 5) is received (step A105).
Here, the measuring means 112 calculates the time from the transmission of the TCP session start request (TCP SYN) to the reception of the start response (TCP ACK), and stores this in the storage area 116 as the response time of the WWW server 410 (step A106). Here, the measuring unit 112 stops measuring the response time.

Further, the measuring unit 112 obtains the route information to the WWW server 410 based on the IP address of the WWW server 410 included in the TCP SYN acquired in step S104, for example, traceroute (trace route: (Step A107).
As a result, the measuring unit 112 acquires a list of IP addresses of routers that are routed to the WWW server (410) that is the target of the route search.

The measuring unit 112 acquires a route search result based on the trace route (step A108), and primary ISP information (Route_info 113b3), which is information of the ISP 310 directly connected to the client node 110, is stored in the storage area 116 in advance. It is determined whether it is registered (step A109).
Here, when the route search result including the primary ISP is not registered, the measuring unit 112 stores the route search result acquired using traceroute in the storage area 116 as route information (step A110).

Next, the transmission unit 113 includes WWW server information (Server_name 113a3) that is information indicating the WWW server 410 to be measured by the measurement unit 112, route information (Route_info 113a5), and a response time (Response_time) measured by the measurement unit 112. In addition to 113a4), response time measurement information (FIG. 7) including the measured time (Get_time 113a2) and the user ID (User_id 113a1) previously assigned to the client node 110 is transmitted to the tabulation search system 200 (step S1). A111: FIGS. 3 and 5).
The WWW server information indicates WWW server specifying information such as an IP address, which is uniquely assigned to each WWW server (410, 420, 430) in advance.

  Next, as shown in FIG. 4A, the control unit 230 of the search tabulation apparatus 200 receives the response time measurement information (FIG. 7) sent from the client node 110 via the receiving unit 231 (step B201). ). Here, the control unit 230 performs authentication based on the user ID (User_id 113a1) as to whether or not the user of the client node 110 that is the transmission source of the response time measurement time is a regular user (step B202: user authentication). ).

  Here, although the authentication using the user ID is illustrated here, it may be set such that more secure user authentication using the electronic certificate is performed between the client node and the total search device 200.

  When the user of the client node 110 is confirmed as a legitimate user by the user authentication, the tabulation unit 232 of the tabulation search apparatus 200 stores the response time measurement result in the response time database 210 as the master table 211 (FIG. 10). (Step B203: FIG. 4 (A), FIG. 5).

[Keyword search]
On the other hand, in step A101 (FIG. 3), when the search means 233 is in the valid state, the client node 110 does not measure the response time of the WWW server and requests the total search device 200 for keyword search.
Here, regarding the operations of the client node 110 and the search tabulation apparatus 200 when it is confirmed that the search function of the search means 233 is valid, the flowcharts of FIG. 3, FIG. 4B, and the sequence chart of FIG. Based on

First, when it is confirmed that the search unit 233 is valid, the processing unit 119 of the client node 110 sets the capture unit 114 to a valid state (step C301).
Here, the capture unit 114 acquires an HTTP request (HTTP GET: FIG. 6) transmitted from the WWW browser 111 to the WWW server 410 (step C302), and a response from the WWW server 410 to the HTTP request (HTTP) Wait until the response is sent to the client node 110.

  When the HTTP response is sent from the WWW server 410, the capture unit 114 acquires the HTTP response (step C303), and from the HTML data included in the HTTP response, information included in the <title> tag and the <meta> tag (hereinafter referred to as “metadata” tag). "Tag content information") is extracted as a search target word (step C304).

  Next, the transmission unit 113 includes the user ID of the user of the client node (User_id 113b1), HTML information (Html_data 113b2-1, 113b2-2,... 113b2-n) including the tag content information, and primary ISP information. A search request 113b (FIG. 8) consisting of (Route_info 113b3) is transmitted to the total search system 200 (step C305: FIGS. 3 and 6).

  Here, the total search device 200 receives the search request 113b (step D401: FIGS. 4 and 6), and the search unit 233 performs user authentication for the search request 113b (step D402).

  When it is confirmed that the search request 113b is a request from a legitimate user, the search unit 233 uses the HTML information (Html_data 113b2-1, 113b2-2,..., 113b2-n) from the search request 113b. (Step D403), and using the search database 220, a search is performed for a WWW server having a Web page on which information similar to the HTML information or information including the HTML information is posted (step D404: WEB). Search (Figure 6)).

  The WEB search is based on a search word or HTML information, and uses a search engine for a website or a WWW server that has a web page including the search word or HTML information, or a search engine that operates on an existing website. May be.

  Next, the search means 233 obtains the search collection information that is the search result of the WWW server (URL) from the search database 220, and calculates the average response time (average response time) of each WWW server to which each search collection information belongs. Referring to the WWW server specific table 212a (FIG. 11) set in the response time DB 210 in advance (D405).

  The search means 233 refers to the WWW server-specific table 212a (FIG. 11) for each search collection information for information such as WWW server information and URL, which are search collection information obtained from the search database 220. In the WWW server (URL) to which the search collection information belongs, the average response time corresponding to the primary ISP information Route_info 113b3 of the search request is acquired, and the WWW server with the short response time is preferentially listed at the top The order of the WWW server (URL) information is rearranged.

  The search means 233 obtains an average response time for each WWW server that is the search result, and creates a WWW search result list in which the WWW server that is the search result is preferentially listed with the WWW server having the short response time. Then, the WWW server search result list is transmitted to the client node 110 that is the transmission source of the search request (step D406).

  Next, as shown in FIG. 3, the client node 110 receives the WWW server search result list sent from the total search device 200 (step C 306), and the display unit 115 stores this WWW search result list in the client node 110. It is displayed on the screen of the display device (step C307). Note that the WWW search result list may be displayed by the WWW browser 111.

  It should be noted that, based on the character information relating to the title of this web page included in the web page (response information) sent from the WWW server 410 to the client node 110, a web page belonging to another WWW server is searched, and the character Character information search function for collecting web pages including information, and search result generation function for generating a search result list by listing information such as collected web pages in ascending order of response time of the WWW server to which the information belongs. May be configured such that the execution content is programmed and executed by a computer provided in advance in the tabulation search apparatus 200.

  As described above, in the present embodiment, the configuration is provided with a total search device that collects route information from many client nodes connected to the Internet to the (target) WWW server and the response time of the WWW server. In addition, it is possible to grasp the length of response time of each route, thereby grasping the congestion status of the entire Internet. Also, based on this congestion situation, it is possible to present a search result for information that takes into account the response time element.

In this embodiment, since response times of many WWW servers are collected from client nodes connected to a plurality of ISPs, the response times of WWW servers to which client nodes are newly connected can be confirmed.
Furthermore, when displaying a web page on the client node side, the content information of the title tag and meta tag included in the HTTP response first sent from the WWW server is searched for a WWW server on which similar information is posted. Since it is used as a search keyword, it is possible to search for another WWW server (URL) without waiting for the entire web page to be displayed on the client node side.

[Modification 1]
As a first modification of the present invention, the basic configuration is as described above. FIG. 12 shows a configuration for reducing the processing load in the entire web search system.
In addition, the same code | symbol shall be attached | subjected about the same structure content as Embodiment 1 mentioned above.

  The first modification of the web search system includes client nodes 110, 120, and 130, ISP 310 that is a server terminal belonging to the network of an Internet service provider connected to each of the client nodes 110, 120, and 130, or the network. 320 and 330, and an ISP 370 that is a network to which the ISPs 310, 320, and 330 are connected in common, each connected to the ISP 370, acquires information from each of the client nodes, and performs a search in response to a request. At the same time, the total search devices 200-1, 200-2, 200-3 for transmitting the search results to the client node are provided.

  In the modification example of this embodiment, the client nodes 110, 120, and 130 are connected to ISPs 310, 320, and 330, respectively. In addition, the aggregation search devices 200-1, 200-2, and 200-3 receive information from the client nodes 110, 120, and 130 connected to the ISPs 310, 320, and 330, respectively, as shown in the above-described embodiment. To collect.

  As described above, in the first modification, when the total amount of data to be aggregated increases by distributing and setting the aggregated retrieval devices of connection destinations for each client node connected to each ISP, Such processing load can be distributed. Further, the response time for the search request included in the master data can be shortened by reducing the data amount of the master data to be aggregated by each aggregation search device.

[Modification 2]
Next, Modification 2 will be described.
As shown in FIGS. 13 and 14, the second modification has substantially the same configuration as that of the first embodiment shown in FIG. 1, but the client nodes 110, 120, and 130 and ISPs 310, 320, and 330 Gateways 610, 620, and 630 that perform protocol conversion between networks and perform relay of communication between them are connected to each other.
Other configurations are the same as those of the first embodiment, and the same numbers are assigned to the same configuration contents.

  In the second modification, as shown in FIG. 14, the client node 110 includes a WWW browser 111 and display means 115 that outputs and displays information acquired by the WWW browser 111 on a preset display device or the like. The measurement unit, the transmission unit, the capture unit, and the storage area, which are functional units provided in the client node 110 in the above-described embodiment, are respectively included in the measurement unit 612, the transmission unit 613, the capture unit 614, The storage area 616 is different from the above-described embodiment and modification in that it is provided in the gateway 610.

  As a result, the gateway 610 has functions equivalent to those of the measurement unit 112, the transmission unit 113, the capture unit 114, and the storage area 116 in the above-described embodiment.

Further, as shown in the above embodiment, the DNS request packet output by the WWW browser 111 is acquired by the capture unit 614 when passing through the gateway 610.
Further, the gateway 610 has various functions such as route information acquisition to the WWW server (410, 420, 430) that is the access destination of the client node, an HTML information acquisition function, and transmission to the aggregation search device 200. As a result, the processing load on the client node can be reduced.

  Further, by setting only the search result for the search request to be transmitted from the gateway 610 to the client node 110, the search result can be acquired on the client node 110 side.

As described above, in the second modification, a part of the functional configuration (means) of the processing unit 119 operating in the client node in the above embodiment is provided in the external gateway 610 connected to the client node. As a result, the processing load on the client node can be reduced.
Further, since the gateway 610 is not assumed to be carried as in the case where the client nodes 110, 120, and 130 are portable terminals, for example, the connection environment for the ISPs 310, 320, and 330 does not change. Thereby, for example, it is not necessary to acquire route information to the WWW server 410 every time, and if the connected state continues once, the route information is retained, so that the ISPs 310, 320, 330, and 370 Such traffic can be effectively reduced.

  The present invention can be applied to a network communication system including a mobile communication terminal connected to the Internet whose use place is expanded against the background of ubiquitous network.
