(explanation of each one of central network server)

(central network server: lastest imformation management department)

" lastest imformation management department " 200 is used for management update information." lastest imformation " refers to the relevant information of renewal with the network data of central network server 101 and local web-server 102.

That is to say, in lastest imformation, comprise information relevant and the information relevant with the network data of local web-server 102 with the network data of central server 101.As the information relevant, for example have and be illustrated in central server 101 1 sides and when upgraded the relevant information of renewal resume of which network kind data with the network data of central server 101.In addition, as the information relevant, for example have with expression when sent the relevant record information of which network data to local web-server 102 with the network data of local web-server 102.

(renewal resume and the transmission resume managed with lastest imformation management department are the action example of foundation)

What Fig. 3 illustrated is that this renewal resume and the transmission resume of being managed with lastest imformation management department 200 are the action example of the network data transmitting system of the present invention of foundation.

At first, be located at central network server side, shown in display box 301, store A, B, C, D, 5 such network datas of E as network data.

At first, if local web-server shown in arrow 302 as network data request A, B, C, D, then central network server can send A, B, C, D shown in arrow 303.In view of the above, shown in display box 304, can store A, B, C, D in the local web-server.At this moment, the lastest imformation management department of central network server will keep sending A, B, the such transmission resume of C, D to local web-server.

Then, be made as the C and the D that in central network server, upgrade network data and become C ', D '.At this moment, having upgraded the such renewal resume of C and D can be kept by the lastest imformation management department of central network server.

Suppose that in local web-server side wish to carry out the renewal of network data, local web-server then as described below and central network server communicate in this desirable any timing.

1. local web-server sends " can send the request of network data table " (arrow 306) to central network server.

2. central network server is according to " can send the request of network data table ", and renewal resume and the transmission resume managed with lastest imformation management department are the form of being made up of C ', D ' according to sending (arrow 307).Receive this form by local web-server, can learn that C ', D ' are updated.

3. local web-server there is no need the network data of asking all to upgrade, and according to its any judgement, specifies needed data among the network data of having upgraded.At this, be defined as asking C ', local web-server request C ' (arrow 308).

4. central network server sends to local web-server (arrow 309) according to request with C '.

The result is that the network data that local web-server kept can be shown in the display box 310.

(central network server: can send the request of network data table and accept portion)

" can send the request of network data table and accept portion " 203 is used for accepting and can sends the request of network data table.For example, in the communication mode that adopts TCP/IP, can send the network data table request portion that accepts the passage (port) of particular number is monitored, till the establishment request that channel is arranged, enter waiting status, and establish channel to receive data according to the request of establishing.Judging whether these data are to send the request of network data table, is the information of the data that send from which local web-server if will obtain.

Herein, " can send the request of network data table " refers to the request that receives from local web-server 102, and is the transmission request that can send the network data table.In addition, " can send the network data table " and refer to the network data table (list) that can send local web-server 102.

Fig. 4 example goes out to send the network data table.In this example, can send the network data table adopts the form of XML to express.That is to say, from＜... to＜/... resemble the parantheses corresponding, by ... part express usefulness＜... and＜/... what the part that brackets is.Under the occasion of the example of Fig. 4, since all with＜can send the network data table and＜/can send the network data table bracket, so express all is to send the network data table, and by＜network data〉2847.html＜/network data etc. to express 2847.html etc. be network data, show the network data discerned with 2847.html as a whole and all can send with the network data that 1331.pp discerns.

(central network server: can send network data table generating unit)

" can send network data table generating unit " 204 generates according to lastest imformation and can send the network data table, and this can send the network data table is the network data table that can send local web-server.This lastest imformation is by lastest imformation management department 200 information of managing in addition.

Fig. 5 represents an example of the lastest imformation that kept by lastest imformation management department 200.In Fig. 5, expressing network data has A, B, four of C, D and local web-server that lastest imformation under two the occasion is arranged.

Storage is the renewal resume of network data in perpendicular row 501.Express network data A and be updated April 1, B is April 1 equally, and C and D were updated April 15.

In perpendicular row 502 storage to be expression sent the transmission resume on the date of network data separately to one among certain two local web-server (below, be called " local web-server 1 ", another is called " local web-server 2 ").Expressing network data A, B, C, D sent local web-server 1 April 10.

Storage is that expression sent the transmission resume on the date of network data separately to local web-server 2 in perpendicular row 503.Express network data A, B, C and sent to local web-server 2 and network data D transmission as yet April 20.

(central network server: the sent network data table that is generated)

According to lastest imformation shown in Figure 5, generation can send the network data table.That is to say, generation can send the network data table and make it to be made up of the identifier (name just) of following network data, and this network data is the network data of being upgraded in central network server on the date after not leaning on to the network data of local web-server transmission or on the date that sends than local web-server.

For example, network data A and B were updated April 1, and they sent to local web-server 1 April 10, owing to not being the date afterwards April 10 on April 1, so can not constitute the sent network data table to local web-server 1.

On the other hand, network data C and D were updated April 15, and they sent to local web-server 1 April 10, owing to being the date afterwards April 10 on April 15, so constitute the sent network data table to local web-server 1.

As a result of, to the sent network data table of local web-server 1 as shown in Figure 6, constitute by C and D.

Similarly, though because for A, B, C be the D that after upgrading, sends also less than transmission, so as shown in Figure 7, the sent network data table of local web-server 2 is made of D.

(central network server: generation can send the processing of network data table)

Fig. 8 example goes out generate the process flow diagram that the processing can send the network data table describes in can sending network data table generating unit.

In step S801, make as pre-service can to send the network data table and soar.

In step S802, judge whether to handle the all-network data.If judge and handle all network datas, will be by sending the sent network data table that network data table generating unit is created on this moment.If judge all network datas that still is untreated, will steps performed S803 processing afterwards.

In step S803, take out a untreated network data, prepare the processing after this data steps performed S804.

In step S804, obtain the renewal day of the network data that is untreated of being taken out from upgrading resume.

In step S805, obtain the transmission day of the network data that is untreated of being taken out from sending resume.

In step S806, judge to send and day whether to express " sending " and just do not send to local web-server, perhaps with send to compare whether upgrade day be after this date day.If this condition is set up, then transfer to step S806, otherwise then turn back to step S802.Moreover, compare the date of upgrading day day and mean with sending for after this, be updated in this network data after local web-server sends network data.

In step S807, append network data to sending the network data table.Also have, this appended be not network data itself, but the identifier of network data (name etc.).After this, turn back to step S802.

(central network server: lastest imformation management department also can possess the history information management portion of renewal and send network data history information management portion (embodiment 2 and embodiment 4))

Also have, lastest imformation is formed by upgrading record information and having sent the network data record information, and lastest imformation management department also can possess the history information management portion of renewal and send network data history information management portion.Fig. 9 example goes out the functional block diagram of the network data transmitting system that is made of central network server and local web-server under this occasion.

(central network server: upgrade history information management portion (embodiment 2 and embodiment 4))

" upgrade history information management portion " 201 is used for the management update record information." renewal record information " refers to the information relevant with the renewal resume of network data.As the example of upgrading record information, the information of when upgrading which network data that has expression central network server 101 to be kept.

As the management method of this lastest imformation, can consider the whole bag of tricks.Figure 10 example goes out to upgrade history information management portion for the employed form of management update record information.In this form, list the identifier that storage is discerned network data at " network data identifier " perpendicular.As the identifier of recognition network data, for example also can use the filename that stores network data.List the date that network data that storage discerns by identifier is updated at " upgrade day " perpendicular.Also have, according to the renewal frequency of network data with frequency is provided, branch unit that also can store network data be updated or the time in second unit and the more tiny unit.

Adopt the form of example shown in Figure 10 to come the supervising the network data when to be updated.In addition, also can storage list in the form of Figure 10 illustrate each network data by how updated information.For example, the not just change of content of renewal operation as network data, and also have the deletion of the re-registering of network data, network data, under this occasion, also can make and express the information of carrying out these which operations of changing, re-registering, deleting and managed with the identifier of network data is corresponding.

Figure 11 example goes out the process flow diagram that the management processing of upgrading record information is described.

In step S1101, wait for until network data being updated.If network data is updated, then transfer to step S1102.Be updated in order to detect network data, following two kinds of methods or the like are for example arranged, the one, the method for making by the people's who upgrades network data notice, the 2nd, the method for coming the notice of the application program of self refresh network data to make.

In step S1102, obtain the lastest imformation of network data.For example, obtain the information of the identifier of carrying out network data, which renewal operation of upgrading day etc.

In step S1103, upgrade upgrading record information.Under the occasion that the renewal record information is managed by the form of example shown in Figure 10, upgrade this form.For example, simply append the renewal record information in form, perhaps whether the identifier of retrieval network data is stored in the perpendicular row of network data identifier, if store the perpendicular row that then can upgrade corresponding therewith renewal day.If storage is not then appended the renewal record information to form.

In step S1104, judge the management of upgrading record information is finished.For example whether should finish that by whether central network server was carried out power-off operation waits and judges.If should not finish, just turn back to step S1101.

(central network server: sent network data history information management portion (embodiment 2 and embodiment 4))

" having sent network data history information management portion " 202 is used for that management has sent the network data record information to each local web-server." each local web-server is managed " and mean, for example can obtain the transmission network data record information relevant under the occasion of local web-server specifying out with this local web-server.In addition, " having sent the network data record information " refers to and the relevant information of resume that local web-server is sent network data.For example, having sent the network data record information is the information of representing when to send which network data.

Figure 12 example goes out that management has sent the used form of network data to each local web-server.The identifier that storage is discerned local web-server in the perpendicular row of " local web-server identifier ", in the perpendicular row of " network data identifier ", store the network data identifier that is sent, in the perpendicular row of " send day ", store and when be sent out.According to transmission frequency, in the perpendicular row of " sending day ", also can store the indicated transmitting time of unit that adopts branch unit and second unit etc.

In Figure 12, for example under the occasion that sends the network data record information that obtains the local web-server that this identifier is discerned with A, can there be the row of A also to be collected in the perpendicular retrieve stored that lists of " local web-server identifier ".

Figure 13 example goes out can send the process flow diagram that the required processing of network data table describes to generating.

In step S1301, make to send the network data table and soar.

Step S1302, S1304, S1305 and S1306 form circulation, and a renewal record information of being managed by renewal history information management portion 201 is carried out once this circulation, carry out the processing of upgrading record information.

In step S1302, judge and whether handled all renewal record informations.Handle all renewal record informations if determine, then transfer to step S1303, and exported as the result who is generated with the sent network data table of this moment.If the renewal record information that still is untreated all is then transferred to step S1304.

In step S1304, take out the next record information that upgrades, prepare the later processing of steps performed S1304.

In step S1305, judge whether should append the network data relevant to sending the network data table with upgrading record information.To illustrate below about this judgement.If should append network data to sending the network data table, just transfer to step S1306, otherwise then turn back to step S1302.

In step S1306, carry out to sending the network data table and append network data.

(whether should to sending the judgement that the network data table appends network data)

Below, relevant whether should being illustrated of in step S1305, carrying out to sending the judgement that the network data table appends network data.

Such situation of for example justing think, Here it is expresses time update date of the time on date that is updated as network data by the renewal record information of being managed in upgrading history information management portion 20 1, by being sent the record information of transmission network data of network data history information management portion 202 management, express the date of shipping time as the time on date that sends network data.Under this occasion, to not send to the such record information of transmission network data of local web-server by upgrading the represented network data of record information if having, that is to say if network data is newly appended, then determine this network data and should send to local web-server, and can constitute and to send the network data table.(that is to say, append network data) to sending the network data table.

Also have, in the network data that this newly appended must be to append to sending the network data table, and when newly appending network data, also can specify the local web-server that should send this network data in advance, just append this network data to the sent network data table that should send to specified local web-server.

In addition, having and to send under the such occasion that sends the network data record information of local web-server by upgrading the represented network data of record information, time update date and date of shipping time are compared, if comparing with the date of shipping time, time update date not time on date of shifting to an earlier date in time, just determine this network data and should send to local web-server, formation can send the network data table.

In addition, expressing under the deleted occasion of network data by upgrading record information, determining this network data should delete from local web-server, and can not constitute and to send the network data table, perhaps append and to delete such information from local web-server to sending the network data table.For example, under the deleted occasion of 5018.pd, also can to＜can send the network data table and＜/can send the network data table between append as by＜deletion 5018.pd＜/deletion represented delete instruction.

(central network server: can send network data table sending part)
