Management server 10 was in the past to concentrate the backbone server computer that carries out network management and be provided with in order to gather.In the present embodiment, its purpose is in order to alleviate the load that this management server 10 is born first.Management server 10 has information management database 12, server admin portion 14, server list management department 16 and server list maintaining part 18.
Information management with database 12 in the storage client terminal with the corresponding relation of management server 43 and client terminal 42 etc. about the customer information of client 40, obtain or upgrade the content information that management object information uses, the management information that reaches content information.The never illustrated input unit of these information is imported, or generates by explaining from the information content of receptions such as content server, or collects from the information specific storage according to the input information content.
And record is used to hold the management information of the information-providing server of disperseing maintenance information respectively in the server 20,30.Server admin portion 14 carries out management, the supervision with servers 4,6,20,30 such as being connected/cutting off, move of information distribution or load dispersing system/stop.Server list management department 16 selectes as the server 4,6,20,30 of client terminal with the access object of management server 43 with the load condition of each server 4,6,20,30 that comprises in database 12 and the network system etc. according to information management, generates the address list (below be called server list) of this selected server 4,6,20,30.And, when this server list is write server list maintaining part 18, send to network monitoring server 30.In the present embodiment, though only just can act on, constitute but mirror image server is set by multiplexed management server 10 by a management server 10.Thereby, even arbitrary management server 10 because the not shutdown such as fault of expectability, even or wait and temporary transient halt system in order to keep in repair, also can continue operational system.
Network monitoring server 30 is equivalent to NOC (network operation center), has network monitoring portion 31, Information Management Department 32 and management information base 33.Network monitoring portion 31 monitors the running status of client terminal with management server 43 by the network monitoring function.Management information base 33 is databases of wherein storing the management information of the content information that is distributed by management server 10.Particularly, the management information of the storage that is updated content information or content information and the information that provides necessary business rule to use to the user are provided in storage.Information Management Department 32 is that performance is as the unit of information-providing server function, corresponding to providing canned data in the management information base 33 from client terminal with the request of management server 43.
Information-providing server 20 has Information Management Department 21 and module database 22.Module database 22 is wherein to store the database of information of being distributed by management server 10.Particularly, the storage client terminal up-to-date module of the knowledge base of management server 43 uses, the content informations such as up-to-date module of rule base.The information that provides in the present embodiment is target (オ Block ジ エ Network ト), is the copy of the example (イ Application ス Application ス) of management server 10 maintenances, is distributed by management server 10.In addition, make client terminal keep the target of management and information-providing server 20 to keep the target of management to be associated with management server 43.By network monitoring server 30 these targets of management.
These information-providing server 20 or network monitoring server 30 be from being the destination device of posting a letter under the situation of management server 10 aspect the posting a letter of management server 10 receiving targets, and management server 10 is the source apparatus of posting a letter under situation about seeing from this information-providing server 20 or network monitoring server 30.
Client terminal has server list acceptance division 44, server list 45, Information Management Department 46 with management server 43.Server list acceptance division 44 receives the server list 45 of sending from network monitoring server 30.The information of Information Management Department 46 managing customer system side has the network monitoring server 30 of appointment in the inquiry server list 45 and whether upgrades inquiry portion 47 to the client necessary information; With when the lastest imformation, collect the information collection component 48 of up-to-date information in the network monitoring server 30 of appointment from server list 45 or the information-providing server 20.
These server groups provide following service basically.That is, in 10 kinds of inputs of management server, information (target information) that maintenance is relevant with target.Regularly this target information is posted a letter to each information-providing server 20 and network monitoring server 30 in accordance with regulations.In the present embodiment, management server 10 can not confirm also whether each information-providing server 20 and network monitoring server 30 carry out normal process according to the target information of distributing to it.The reasons are as follows described.
Information-providing server 20 is according to the target information that the receives processing that puts rules into practice.For example, be about the correction data of software module or insert under the situation of sign indicating number (software upgrading data) canned data,, obtain among the URL that then from target information, comprises and keep revising data as if obtaining in target information.Though the various contents of information-providing server 20 such collections etc., all types of target information or wait based on the information that it is obtained and to move, but under situation about can not collect for a certain reason, also can interrupt down collecting in rated condition (for example can not collect at the appointed time etc.).
Network monitoring server 30 is according to the target information that the receives processing that puts rules into practice.Network monitoring server 30 is about software module correction data or inserts under the situation of the information that sign indicating number exists in for example target information, keeps the customizing messages of this software module or as revising data or inserting the module release of sign indicating number object and be called the summary info that upgrades the back version.
Corresponding to request, to these information that keep by information-providing server 20 or network monitoring server 30 of posting a letter as client's side of request source from client's side.Therefore, in this case, information-providing server 20 or network monitoring server 30 are the source apparatus of posting a letter of information, and client's side is the destination device of posting a letter of information.The regular accesses network monitor server 30 of client's side, its running status is reported on the limit, limit, the summary info that obtains according to target information is obtained on the limit, carries out the renewal of software module, at this moment, to information-providing server 20 request renewal data.Information-providing server 20 is returned the summary info (version) of the more new data that keeps in the requested software module.Client's side judges that whether the more new data of the version shown in this summary info is necessary, then obtains more new data where necessary.At this moment, when more the version of new data was than the old regulation version of up-to-date version (for example be before more than three version etc.), client's side was reported the meaning that lastest imformation not provides the information on the server 20 to management server 10 directly or indirectly.
That is, do not communicate between management server 10 and the information-providing server 20, but must be judged as the information of unusual information-providing server 20 from client's side-draw about client's side.Therefore, management server 10 needn't confirm whether carry out normal process according to the target of distributing.Even this to network monitoring server 30 too.That is to say,,, then directly or indirectly notify management server 10 network monitoring servers 30 unusual if network monitoring server 30 and client terminal are slower than setting with the communication speed (throughput) between the management server 43 in client's side.
In addition, in the present embodiment, not only management server 10, but also multiplexed each server 4,6,20,30.This is because each server 4,6,20,30 becomes by 40 visits of a plurality of clients, thereby has disperseed the load born separately.Therefore, initial stage of the few system and arranging of the client that connects constantly, even respectively 1 perhaps enough, but the increase of the client number of accepting along with a station server 4,6,20,30 then may reach the boundary of disposal ability.Therefore, among Fig. 1, under multiplexed state, illustrate each server 4,6,20,30.Each server 4,6,20,30 suitably increases mirror image server by the client quantity considering to connect and server computer capacity etc.In addition, in the present embodiment, be conceived to the load difference of each processing or utilize number of times poor, the service of the solid data of data etc. is revised in the service and posting a letter of being carried out the information of the what is called of posting a letter " correction data " by different servers.Therefore, under the situation of carrying out mirror image, can independent adjustment information provide the quantity of server 20 and the quantity of network monitoring server 30.That is, these quantity also can be different.
Present embodiment is characterised in that, generates server list by management server 10, and client terminal is with can actively directly visiting each server of setting in its server list 45 on the management server 43.Thus, management server 10 since when utilization usually not by client 40 any visits, so can realize lightening the load.
As mentioned above, though the client terminal in the present embodiment is directly visited each server 4,6,20,30 with management server 43, but because must need the server list 45 of each server 4,6,20,30 address of expression, so the processing when newly-generated server list 45 at first is described.
When importing client terminal with management server 43 for the first time in the load dispersing system, the server list management department 16 of management server 10 generates as the illustrative server list of Fig. 3 with management server 43 its client terminal.Here, the data structure of tabulating with Fig. 3 prescribed server.
In server list, as the form that each client terminal is generated with management server 43, login is as the address of each server 4,6,10,20,30 of access object.In the present embodiment, login normally used elementary and pick up with two secondary list of group-addresses.For example, as shown in Figure 3, the client terminal of additional this server list is visited the management server 10 of " MS1 ", the network monitoring server 30 of " NOC1 ", the information-providing server 20 of " DC1 ", the dns server 4 of " DNS3 ", the NTS server 6 of " NTS1 " usually with management server 43.In addition, for convenience, only as " MS1 ", represent among Fig. 3, but in fact as mentioned above, login the address of each server 4,6,10,20,30 with server name.
At first, management server 10 is obtained the load condition of each server that moves in the load dispersing system with the server list group that keeps in database 12 and the server list maintaining part 18 by information management.That is, hold each server of operation by server admin portion 14, the sum of each server of appointment obtains the load of each server in each server list that keeps in load condition of collecting according to server admin portion 14 and the server list maintaining part 18.
For example, if be conceived to network monitoring server 30, here, according to the load etc. that calculates every, select NOC1, NOC2, NOC3 ... in any as client terminal network monitoring server 30 with management server 43 visit.Wait the selected network monitoring server 30 of distributing to client terminal with management server 43 by the load of each server of obtaining thus and system capability, the resource surplus of each server.In example shown in Figure 3, with regard to network monitoring server 30, for client terminal with selected best respectively " NOC1 " of management server 43 as elementary, with inferior good NOC3 as secondary.Management server 10 such calculated loads are selected a client terminal each server 4,6,10,20,30 with management server 43 visits respectively, generate the address list of chosen server.In addition, in practice,, but also can set more groups as long as it is just enough to prepare two groups of primary and secondaries.
The server list that so generates is posted a letter to client terminal management server 43, then, the processing when illustrating that with reference to Fig. 4 client terminal imported with 43 initial stages of management server.
Newly-installed client terminal is used the IP address of setting arbitrary network monitoring server 30 in the management server 43 in advance in client 40.After the startup, client terminal usefulness management server 43 receives from authentication informations such as the ADSL of client terminal 42 inputs or CATV, is connected with ISP3 (S1).After the connection, client terminal is obtained this authentication information (S2) with management server 43 from ISP3, extracts specific user's information from this authentication information, and sends to network monitoring server 30 (S3).Network monitoring server 30 transmits the user specific information (S4) that can send to management server 10, and management server 10 is according to user specific information, and specific client terminal corresponding to this user is with management server 43.In addition, with client terminal with the server list of management server 43 and when being provided with again indefinite client terminal send to network monitoring server 30 (S5) with the information of management server 43.Network monitoring server 30 transmits the information (S6) that can send to client terminal with management server 43.
Client terminal is obtained server list as mentioned above with management server 43, and carries out initial setting according to the information that can send.Can understand in the explanation afterwards, when server list management department 16 handles with the information gathering of management server 43 at the execution client terminal, do not carry out any processing for acquisition of information, only keep that client terminal to use the information of that server list with management server 43.In addition, in a single day management server 10 generates server list, then notifies each server 4,6,20,30 of visiting appointment this server list from that client terminal with management server.Also can send the server list former state that generates to each server 4,6,20,30.
Below, the action when lastest imformation is described.
In the present embodiment, for example " take out the services package 1 of the V1.0 of 0S1.Its storage is A "; about the information of the management object that is called 0S1V1.0; calling the content information (knowledge) when being input to management server 10 of obtaining services package; management server 10 is explained the content of the information (knowledge) of input, obtains the content information (content) of services package from the storage A of appointment.In addition, this content information is stored in information management with in the database 12, simultaneously, sends to each information-providing server 20.After confirming that this transmission processing finishes, lastest imformation (management information of content information) is sent to network monitoring server 30.In addition, content information is stored in the module database 22, lastest imformation is stored in the management information base 33.
Below, the processing when illustrating that with reference to Fig. 5 client terminal carries out information gathering with management server 43.Omit ISP3 among Fig. 5.At first, with in the management server 43, inquiry portion 47 is according to the network monitoring server 30 of the setting content specific access object of server list 45 at client terminal.And, regularly, for example inquired this particular network monitor server 30 whether information is updated (S11-1-S11-n) in per 1 minute.If server side from managing customer, then this is inquired and is the running state monitoring (affirmation of connection status) of client terminal with management server 43, if from client's side, the affirmation that then has replying also of unmatchful this inquiry whether to be in operation (whether effective (alive)) for network monitoring server 30.Network monitoring server 30 as the inquiry object is NOC1 in example shown in Figure 3.Inquiry content (information category of inquiry) login is in advance used in the management server 43 at client terminal.The Information Management Department 32 of network monitoring server 30 checks with reference to management information base 33 whether specified message is updated in the inquiry.With above-mentioned example is benchmark, is exactly inquiry content about OS1 from client terminal with the inquiry content of management server 43.
Here, if inquiry message is updated, then client terminal receives corresponding management information (S12) with the Information Management Department 46 of management server 43 from network monitoring server 30.The information of sending from network monitoring server 30 is the information that capsule (kapsel) is changed, and generates new module, and it comprises from indications such as login begin from then on not download the module database 22 of that information-providing server 20 as information.Therefore, take out corresponding information information collection component 48 is indicated in the information-providing server 20 of appointment in capsule, promptly under this routine situation be new module (content information) (S13).In fact, become the information-providing server 20 of " DC1 " of appointment in the access server tabulation 45.If the information that obtains then sends to this client terminal 42 from the request of the client terminal 42 that connects, in addition,, then use in inside if own essential.
Be essential information, the handling process in the load dispersing system above, but according to present embodiment, client terminal is not visited any management server 10 during with management server 43 acquisition of informations.That is to say, can realize alleviating the load of management server.Particularly, according to present embodiment, even client terminal increases with the quantity of management server 43, also only in the server list maintaining part 18 the record quantity of login increase.That is, infinitely increase with the quantity of management server 43 and then client terminal 42 even increase client terminal, the load that management server 10 is born is increase also.In addition, by append client terminal management server 43 to system, the quantity of login in server list maintaining part 18 is the address value of several servers, and the load to management server 10 does not exert an influence.Thus, in the present embodiment, client terminal with management server 43 when acquisition of information, even do not receive from the indication of management server 10 etc., also can be actively from corresponding server 4,6,20,30 direct acquisition of informations, so management server 10 is not applied any load.In addition, client terminal with management server 43 when acquisition of information because access management server 10 not, so even do not stop the load dispersing entire system, also replaceable management server 10.In addition, by multiplexed other server 4,6,20,30, but replace on operational system limit, limit.
In addition, under the situation outside the so-called load dispersing purpose, because can be by single management server 10 input, generate or obtain information, obtain or upgrade the content information that management object information uses and the management information of content information, so can effectively collect, manage necessary information about client.In addition, if only carry out effective information management, do not consider the purpose of so-called load dispersing, then monitor the status of action of client terminals with management servers 43 by management server 10, just processing capacity that will management server 10 is disperseed to network monitoring server 30 and information-providing server 20.
Judge the load condition of information-providing server 20 or network monitoring server 30 with transfer rate (throughput) information of management server 43 when these servers 20,30 are obtained information by client terminal.When the load of server 20,30 is high, think slack-off from the response of these servers, so change the frequency of inquiry according to transfer rate information, for example, when agreements such as using pulse signal (ping) agreement is carried out time action affirmation (whether effectively checking), the interval of changing this confirming operation.For example, when the throughput shown in the transfer rate information diminishes, think the load height of server, so will once be reduced to two minutes once from one minute to the interrogation frequency of server.
Here the processing that illustrates when breaking down in arbitrary server etc.As mentioned above, client terminal is regularly inquired network monitoring server 30 with management server 43.In the present embodiment, this inquiry is used for the supervision of client terminal with management server 43.In the above-mentioned explanation, network monitoring server 30 understanding in advance by which client terminal is conducted interviews with management server 43, in addition, conducts interviews with some cycles when regular event.Therefore, when not conducting interviews within a certain period of time, can judge management server 43 shutdown of this client terminal.In addition, network monitoring server 30 notice management servers 10 client terminals are shut down with management server 43.
In the present embodiment, as mentioned above, can confirm client terminal with the running-active status of management server 43, but this moment also with management server 10 no any relations.That is, even also can hold the running-active status of client terminal, so can alleviate the load of management server 10 with management server 43 without management server 10.In addition; when client terminal is thought change and is obtained server list 45 owing to reasons such as shutting down disappearance with management server 43; because obtain not from management server 10 and from network monitoring server 30 and to move, so even also can not apply load in this case to management server 10.
In addition, when client terminal was inquired network monitoring servers 30 with management server 43, network monitoring server 30 stopped.At this moment, client terminal with management server 43 by in the time of determining with the relation of load condition never response judge that network monitoring server 30 shuts down.Thus, client terminal switches to the server group used secondary from server list 45 elementary with management server 43, begin the network monitoring server 30 of operation is inquired.Thereby can proceed the collection of information.Example as shown in Figure 3 switches to " NOC3 " to the access object of network monitoring server 30 from " NOC1 ".
At this moment, client terminal does not have the meaning of response to think that fault message is notified to " NOC3 " with management server 43 with " NOC1 ".In addition, NOC3 sends to management server 10 with this fault message, the notice fault.
In addition, network monitoring server 30 also can often monitor by multiplexed parts.At this moment, can be by learning with other network monitoring server 30 instant detections of " NOC1 " multiplexed formation.In addition, other network monitoring server 30 is shut down to the network monitoring server 30 of management server 10 notice NOC1.
In a single day management server 10 receives this signalling trouble; then visit is shut down the client terminal management server 43 regeneration server list of network monitoring server 30, send to client terminal management server 43 via newly being appointed as elementary network monitoring server 30.The content that regeneration is handled is identical with above-mentioned generation processing, so omit explanation.Thus, use the secondary client terminal that carries out server access also to be to use the elementary corresponding server that visits with management server 43.
Therefore, the number of operating each server 4,6,20,30 reduces because shut down, but then, because the load of each server 4,6,20,30 is increased, so may increase by newly appending mirror image server.But, even number increases, if not update service device tabulation then can not be visited.Therefore, management server 10 has along with operating number of servers changes forced regeneration and becomes the function of server list.Thus, can impartial carry out the load dispersing of each server 4,6,20,30.
Here, if constructing the step illustrated network monitoring server 30 of mirror image server, then at first, in computer as network monitoring server 30 duplicate objects, as the service switching (サ-PVC ス サ-Block レ Star ト) in HTTPS ' storehouse, starting the initialization service provides with system and the service of oneself managing with system.In addition, this meaning is understood in the 10 beginning initialization services of this computer oneself notice management server.Management server 10 is reproducible as if this notice is defined as, and then permits as mirror image server and moves.This computer inquiry management server 10 of accepting this permission (triggering) is as the essential information of network monitoring server.If collect then to be reflected to the database of maintenance from the answer of management server 10, begin service as the network monitoring server, give management server 10 with this intention notice simultaneously.
As mentioned above, can construct the mirror image server of each server 4,6,20,30, the notice of the server that management server 1O appends corresponding to making a fresh start is implemented the regeneration of above-mentioned server list automatically and is handled.
In addition, can realize generating and sending in the management server 10 processing of server list or client terminal with visiting corresponding processing such as network monitoring server 30 according to server list 45 in the management server 43 by application program, this application program can write can be by the electromagnetism such as recording medium, for example CD-ROM or DVD-ROM of each embodied on computer readable, keep in the recording of information medium optically.That is, by from the recording medium set up applications, can realize above-mentioned each server 4,, each function of 10,20,30,43.In addition, even the above-mentioned application program that obtains by network is installed too.
In the present embodiment, the client terminal management server 43 of managing customer terminal 42 is set, logon server tabulation therein 45, but, then can from client 40, remove client terminal management server 43 if management server 10 directly or via network monitoring server 30 is posted a letter to each client terminal 42 after generating server list.
In addition; in explanation before this; as fault diagnosis example only example the situation of server outage; but in the present embodiment; such as already described; collect when the information of object is provided in information-providing server 20,, interrupt down collecting in rated condition (for example can not collect at the appointed time etc.) at the moment because under the high any former thereby situation about can not collect of load.Therefore, under certain situation, the services package of collecting with DC1 (revising examples of data) be version " 1 ", and is " 2 " with the version of the services package of DC3 collection.
At this moment, client terminal as client's side is " 1 " with the OS1 services package version that management server 43 identifications are installed in the client terminal 42, be the information of " 2 " from the network monitoring server 30 so-called services package version that comes out, although visited DC1, but the services package that keeps in DC1 is 1 o'clock, can detect DC1 and correctly not upgrade.So send the fault message that expression DC1 does not normally upgrade processing to network monitoring server 30, network monitoring server 30 is with this fault message notice management server 10.Management server 10 can be indicated the services package of collecting version 2 to DC1 once more, also can check the server list of each client's side, from the server list that comprises DC1, generate new server list behind the deletion DC1, to this newly-generated server list of posting a letter corresponding to client's side of this server list.
In addition, here for example understand the situation that under the situation identical, is identified as fault with the version of client's side maintenance, but under the low situation of version that the version that information-providing server 20 keeps keeps than client side, also can be identified as fault, more than setting, be identified as fault in the difference of the services package version of services package version and information-providing server 20 maintenances of notice.
In the present embodiment, the large scale network that client or number of servers are extremely many is also contained in this example.As mentioned above, under this large scale network situation, the information version that keeps in each server has nothing in common with each other.Therefore, also produce and so-calledly also do not obtain situation corresponding to the services package entity of the latest edition of network monitoring server 30 notices for a certain information-providing server 20 on the server list.In this case, client's side direction management server 10 report fault messages to information-providing server 20 visits several times, can not be realized lightening the load.
Therefore, in the present embodiment, client terminal carries out following action with management server 43.That is, client terminal is installed OS1 with management server 43 to the client terminal 42 that is arranged in same client system 40, the services package version (current version) that management wherein is suitable for.In addition, client terminal with management server 43 when network monitoring server 30 is obtained so-called information as the latest services bag, the current version of the services package version (latest edition) that relatively comprises in this information and management.
Here, if latest edition then with reference to server list, is visited an information-providing server 20 (use the example of Fig. 3, be made as DC1) that wherein comprises newer than current version.Here, whether the version of checking the services package that this DC1 keeps is latest edition.If latest edition then obtains this services package and end process, but under the situation that is not latest edition, further compare the version and the current version of the services package of DC1 maintenance,, then obtain this services package and end process if the version of services package is newer than current version.
That is, in the present embodiment,,, then we can say and carried out so-called suitably the obtaining of end process after these correction data of obtaining if renewable version is newer than current version although be not latest edition.In addition, when DC1 did not provide the services package of latest edition, (being between DC1 and the DC3 in the example of Fig. 3) compared the services package version that they provide between each information-providing server 20 on server list, obtains newer version here.
According to above embodiment, can effectively carry out about client information, obtain or upgrade collection, the management of the management information of content information that management object information uses and content information.
In addition, for generating server list and providing the server of object during with the management server acquisition of information according to the server list information of being made as at client terminal, even because do not receive from yet actively directly visits such as the indications of management server, so needn't access management server.Thereby can alleviate the load of management server.In addition, because do not conduct interviews with management server, so even the yet replaceable management server of halt system not from client terminal.
In addition, because regeneration server list during the network monitoring server outage, so always can provide client terminal with the tabulation of management server effective service device.
In addition, because prepare many group server list, even, also can continue to visit operating server by switching to other server list in the arbitrary server outage that constitutes the server list in using.
In addition, because will regularly have or not the inquiry of lastest imformation to be utilized as effective information, so can confirm that in the network monitoring server this client terminal moves with management server to the network monitoring server.
