Abstract
Transmit the method for resource information at each intercomputer of computer network with complete distribution mode.Each when subscriber computer networking work, send a request message from subscriber computer to one or several predetermined server computers, every predetermined server computer determines itself whether can make the resource of user's computing machine earlier when response request message, can whether use according to server computer, server sends a positive response message or a negative response message to subscriber computer respectively.When a station server can be used as the resource of or several subscriber computers, it sent a requisition message to one or several preparation subscriber computers.
Description
The present invention relates generally to computer network, more specifically say, relate to resource information is disperseed method to each network computer,, make as sharing computer resource between each computing machine in this class network of distributed treatment to form a distributed data base.
The realization distributed treatment has been done a large amount of work at present in computer network.Distributed treatment has produced at those carries out operation between computing machine that congested computing machine and those leave residual capacity and divides equally, thereby has improved network efficiency.For example, the user can transfer to the computing machine that is adapted to this class operation especially with some such as time-consuming operations of this class such as text formatting, floating-point operations from home computer.
In the network of the resource that allows to share, every computing machine is all planned the resource of other calculating function in the network as this machine usually.
In some system, on a computing machine, finish centralized resource name services in the network separately.A computing machine is delivered to this computing machine with request, find out which platform computing machine can with its shared resource.If these independent computing machines break down, Internet resources are shared with the resource name Service and are just accused interruption.Another shortcoming of this centralized solution is to proceed needing central computer of extra access before the processing.Since these and other some reason, the distributed name Service of some network using.(can report, and in Dec, 1981, P.169-177) the LOCUS system of a literary composition introduction is exactly an example of virtual centralized name server by ACM-SIGOPS the 8th layer operation system of IMS conference in " network readezvous point and reliability distributed system " for people such as G.Popek.It makes virtual computing machine of computer network energy emulation.This technology has unnecessarily been sacrificed the autonomy of each computing machine in the network to a great extent.
Another kind of centralized name server is people's proposition " CSNET name server " (Dutch publishing company such as M.Solowion; Computer network 6(1982), P.161～172).But, when each computing machine is received server info, the part of this information is kept in this system, thereby has alleviated some problem of centralized server.
Once introduced a kind of distributed system in " scientific and technological information station a: decentralized institution determining to compose the life object's position under the distributed environment " (american computer association office information system journal, the 1st volume, the 3rd phase, July nineteen eighty-three) in the literary composition.I.Gertner and R.hindenberg had once introduced the part distributed data base name server in the another kind of loop network in " initialization of Wide Area Network duplicate name character server " literary composition.
Above-mentioned distributed name server, each comprises that all some adjusts the ten minutes complicated algorithm in each separate data storehouse for adapting to network change.The problem that must propose comprises: should be what if when a computing machine adds network, how to guarantee the consistance of repeating part in the distributed data base, how to learn that a certain server devotes oneself to work, how with this advisory user, and should be what if when a server is got back to the networking state, or the like.
United States Patent (USP) 4,423,414 enterprises adopt broadcasting scheme to solve above-mentioned some problem in network.Want to carry out the standby family of giving of program process a long way off to information of indicating program of Web publishing.Those computing machines of discerning this program respond.First computing machine that responds is selected.
According to the present invention, utilize a kind of in computer network each intercomputer transmit the method for resource information, make these problems obtain solution.Each when subscriber computer networks, give fixed server computer from this subscriber computer to one or several and send a request message.When this request message of response, whether every book server computing machine determines to make in this server computer requested resource can use for subscriber computer.Then, server calculates the response message that sends positive or negative according to being requested the undirected user of having of resource on the server computer respectively.
In addition, when the resource of a server computer can be used for one or several subscriber computers, this server computer sent requisition message to one or several preparation user.
A computing machine may prepare the availability that the user cancels resource to one or several.This is achieved in that sending one to relevant subscriber computer stops to take over for use message.Above Gai Shu this method owing to realized the distributed resource name server, and since its allow to have interim inconsistency between the resource data of various computing machine, so reliable, and can allow individual computer to break down.In disclosed most preferred embodiment, can support the CPU (central processing unit) itself that utilization or disabled resource are actually computing machine.For example, a computing machine might be made the usefulness of teleprocessing for another computing machine, maybe can not be used as such.Yet the present invention is not limited thereto, and resource can be anything, for example equipment (printer etc.), file, or the like.
Every computing machine in the network all comprises a server database and customer data base.In server database, every All-China Federation of Taiwan Compatriots net computing machine that might be used as the resource of this computing machine is at any time all had a number." permission " sign in each an article or item in a contract indicates and prepares the real server whether server can be used as this computing machine this moment." requisition " sign in this database in each an article or item in a contract indicates the preparation server computer and whether has notified this computing machine, oneself can be used as its resource.Equally, in customer data base, every network computer all has an an article or item in a contract, might make this computing machine become its server at any time." permission " in each customer data base an article or item in a contract indicates to indicate relevant given standby family and whether can become the actual user now.Whether " requisition " in each an article or item in a contract sign indicates this computing machine and has notified and give standby family and itself can be used as its resource.
Below be to make computing machine become the typical method of calculation server, computing machine sends requisition message to the network computer of all permissions of login in customer data base.In addition, computing machine also can send requisition message to selected user's an article or item in a contract subclass.All computing machines of receiving requisition message availability of login calculation server in the relevant server an article or item in a contract in the home server database.When server issue requisition message, certain subscriber computer is work not, also may be at the off-grid state.The computing machine that sends requisition message is no matter subscriber computer is in any state all with " requisition " flag set in its customer data base, for avoiding the problem of inconsistency of database between server and the user, computing machine automatically sends a request message, askes to all selected potential users in the server library when it is networked and looks into usability status.Can not be used as the computing machine of server at present for negative answer message of request message loopback.Otherwise, affirmative reply of its loopback.
Computing machine receive from server stop to take over message for use the time, relevant " requisition " sign is resetted, from its effective server registers table, this server is removed.
If a station server after sending requisition message fault has taken place, when subscriber computer enterprise is used as resource with this calculation server, can detect fault.When this class situation took place, subscriber computer resetted relevant " requisition " in home server database sign.When calculation server recovered the networking state, it issued requisition message again.
In case server sends requisition message to the user, the user just may begin operation, for example finishes its kind teleprocessing on server.This is to be finished by the connection message that is sent to server from the user.After connecting successfully, between user and server, just set up a special-purpose communication approach.Send the user " disconnection " order or server to this user send stop to take over message for use before, this communication approach will remain unchanged always.
Communication between user and the server is finished through the one-way communication passage.The receiving end of computing machine upper channel is called the communication unit that receives descriptor by one and determines.Receive descriptor and point to a formation of pending input message such as depositing.It also links with explain one of message or one group of process to this descriptor.The transmitting terminal of passage is by one and be called the communication unit that sends descriptor and determine.Before sending message to server, the user at first sets up a passage receiving end that is used for the reception server response.The condition code of passage receiving end is included among the message, makes server can set up corresponding transmitting terminal with passage.
Fig. 1 and Fig. 2 have illustrated the form of customer data base and server database in every All-China Federation of Taiwan Compatriots net computing machine.These databases that are positioned at each computing machine determine respectively other computing machine can be used as server to this computing machine for which, can be used as the user to for which;

In the optimum implementation that the present invention proposes, every network computer is a kind of trade mark of American Telephone and Telegraph Company by UNIX(UNIX) operating system control is not that the present invention only is confined to this certainly.
Every computing machine all has a subscriber computer database and a server computer database.Information distribution in these databases makes the database in every computing machine only deposit the information relevant with this computing machine at whole network.Fig. 1 shows customer data base 100.In the customer data base 100 of computing machine, listed in the network that this calculates function and is used as other all computing machines of calculation server for their constantly in difference.Yet, make this calculate function as the server that gives standby family, an an article or item in a contract is not enough in the customer data base 100.In addition, server must be to giving standby family issue requisition message, and explanation itself can utilize, and these two computing machines must get up in " connection " simultaneously.Meaning to these sayings also can obtain further understanding in the following description.
In customer data base, each is given the standby an article or item in a contract that has separately per family.As shown in Figure 1, an article or item in a contract comprises user name 101, user for the password 104 that is adopted, the reception descriptor 105 that gives standby indoor network server process of maintaining secrecy, and one group 106,108 such signs.User name is used for indicating uniquely the computing machine in the network.Here the so-called descriptor 105 that receives is actually an address that can be converted to the reception descriptor.In general, receive descriptor indicate on a computing machine and the computing machine will with the joining special file of given process.Reception descriptor 105 is indicated and is led to the relevant communication channel that is equipped with network server process on the server computer that gives, therefore can see nonvolatil information as.It always exists, and makes this calculating function and gives the computing machine communication of standby family.
Here interested sign is " permission " sign 106 and " requisition " sign 108.When this computing machine be by the determined network computer of user network label when the server, " permission " flag set.Illustrate that as an example this permission can be finished under computer administrator's control.When this computing machine to giving standby family computing machine issue requisition message when can be used as server, " requisition " flag set.Other remaining in customer data base sign is useless to understanding the present invention.
Fig. 3 shows the program step that other network computer that a computing machine finishing logins announces can be used as resource in its customer data base in the present embodiment.Yet, before introducing Fig. 3, preferably consult Figure 11 earlier.Figure 11 shows two network computer RAVEN and EAGLE.RAVEN and EAGLE comprise the webserver 1100 and 1102 respectively.The webserver is one program, and it receives message from other network computer, and by rights they is handled.For example, the webserver may be contact for the first time being used as on the computing machine of email disposal.In this case, the webserver also is used to receive the message that other computing machine is sent here inter alia, set up communication channel according to requisition message at each intercomputer, start teleprocessing server (teleprocessing requested service program) according to the teleprocessing request, and between subscriber computer and teleprocessing server, set up direct communication channel.
Every computing machine in the network, for it can with every of its communication other network computer, all have one and receive descriptor.This receives descriptor and has 105 and 212 of customer data base and server database respectively.In Figure 11, this receives descriptor and is equivalent to the rd1 of RAVEN and the rd2 of EAGLE.Note, receive descriptor rd1 and rd2 and link with the map network server 1100 and 1102 of RAVEN and EAGLE respectively by communication channel.If RAVEN will send a message to give EAGLE, it is finished like this: take out reception descriptor rd2 from a relevant customer data base or server database.Equally, EAGLE utilizes from its customer data base or the rd1 and the RAVEN communication of server database acquisition.
Consulting Fig. 3 just can understand requisition message and how give fully server from one and deliver to and give standby family.When doing this explanation, please the reader consult Figure 12 simultaneously.When the computer administrator asks, when perhaps computing machine (for example EAGLE) dropped into network, program entered " requisition " program 300 among Fig. 3.Program block 301 makes it carry out circular treatment to the whole an article or item in a contracts in the customer data base 100 " requisition " program initialization.After whole an article or item in a contract processing end, program is in 302 outlets.For the customer data base an article or item in a contract of handling at present (for example RAVEN), by " permission " sign in the program block 304 check an article or item in a contracts, to determine whether this computing machine can give the server at standby family as this at present, remember that " permission " sign proceeds to set or resets under computer administrator's control.If " permission " sign is reset, then omit this an article or item in a contract, program circulates to the next an article or item in a contract in the database.If this flag set is then set up requisition message in loop blocks 306, it comprises the name of taking over computing machine for use.Program block 306 is then opened the transmission descriptor Sd1 of an EAGLE, and utilizes Sd1 will take over the webserver 1100 that message is delivered to RAVEN for use.It adopts and receives descriptor rd1, makes the passage of requisition message in network deliver to RAVEN.Program block 308 is with " requisition " flag set in the RAVEN an article or item in a contract in the customer data base of EAGLE.Like this, give server (EAGLE) fully hereto, it has notified this to give standby family (RAVEN), and this machine can be used as resource.Then, other an article or item in a contract in the EAGLE customer data base is carried out re-treatment.
As the response to requisition message, " requisition " given in the server database at standby family indicates 208 set, below will cooperate Fig. 4 to be further described.Note that does not need to answer message, and the computing machine of requisition is not expected to obtain the answer message that message is taken in response for use from giving standby family yet.According to the present invention, the requisition computing machine need not to adopt and specially gives anti-measure and guarantee that the server database that gives standby family done suitable adjustment.If give standby family off-grid, then the server database of subscriber computer will be adjusted by request message when it is networked again a little later the time.
Take over message when needed for use and can only send to the computing machine in the network rather than the computing machine of the whole permissions in the customer data base.In this case, " requisition " program among Fig. 3 is directly from program block 304 inlet, will receive to take over message for use and be used as and give standby family input parameter.For simplicity, this order does not illustrate in Fig. 3.
Fig. 4 shows and give the program step that standby family computing machine is carried out when response requisition message.Giving on the standby family (RAVEN), receiving requisition message by rd1, and deliver to the webserver 1100.The webserver 1100 calls " receiving requisition " subroutine 400 shown in Figure 4.Program block 401 utilizes the name of server in the requisition message, finds number of computer servers according to the relevant an article or item in a contract in the storehouse.If an article or item in a contract does not find, then do not consider this requisition message." permission " indicates whether set for this server in program block 402 check.If indicate not set, then computing machine does not plan to use relevant server, so, 400 ends of subroutine that this " receives requisition "." if permission " flag set, then program block 404 is with " requisition " flag set in an article or item in a contract, with the availability of record server.
Fig. 5 shows the flow process of " stopping requisition " program 500.This program is finished on server computer, is used for making this computing machine not to be re-used as server and uses.In the embodiment of our demonstration, this is according to finishing from computer administrator's a order.Program block 501 makes the whole an article or item in a contracts in computer user's database can both obtain handling a loop program initialization.After whole an article or item in a contracts dispose, circulate in 502 outlets.When finding first an article or item in a contract at customer data base, whether program block 504 is determined to indicate set for the relevant standby family " requisition " of giving in the customer data base of server computer.If it does not have set, then omit this an article or item in a contract; Continuation is handled next an article or item in a contract.Otherwise program block 506 produces one and stops to take over for use message, and it comprises the name of computing machine, and utilizes the reception descriptor rd1 in the customer data base that it is delivered to subscriber computer.Program is not waited for or is asked the user to receive the recall signal of message.At last, program block 508 resets " requisition " in this database an article or item in a contract sign, finishes this kind of purpose is handled.Then, loop program repeats other an article or item in a contract in the customer data base is handled.If above-mentionedly for various reasons stop to take over for use message and do not received by subscriber computer, this situation will be afterwards when the subscriber computer request of sending or when this computing machine sends the teleprocessing request, handle again.Under latter event, the subscriber computer request was lost efficacy, and caused " requisition " mark of this computing machine to reset.
Also as the situation of issue requisition message, " stopping requisition " if program program block 504 inlets and with the subscriber computer name as input parameter, then can only send and stop to take over for use message to a subscriber computer.
Fig. 6 shows computing machine and receives performed program step when stopping to take over message for use.Program block 601 utilizes the server name that stops to take over for use in the message, finds relevant an article or item in a contract from its server database.Certainly, if do not find this an article or item in a contract in database, this message is not just considered.Otherwise, " requisition " in relevant server database an article or item in a contract sign is resetted at program block 602.
When computing machine stop or off-grid after when networking again, server database may lose efficacy.For instance, when the computing machine off-grid, may have one or several network computers and send requisition or stop to take over for use message, all not receive certainly to this computing machine.The program of Fig. 7 gives fully to it whole that server sends a request message, adjusts its server database.In the embodiment of this demonstration, " request " program 700 is to network or carry out during the request of receiving the computer administrator at computing machine.Program block 701 is a loop program initialization, makes it can handle whole an article or item in a contracts in the server database of this computing machine.For first an article or item in a contract, by the state decision of program block 702 according to " permission " sign, whether relevant server computer may be server.Please remember that one is given fully server and whether permits that becoming server is determined by the computer administrator at any time.Be equipped with computing machine without approval if give, then do not consider this an article or item in a contract, circulate in program block 701 and continue next an article or item in a contract is handled.Otherwise, give fully server 704 pairs of program blocks and set up a request message.Consult Figure 13 (supposition RAVEN is a computing machine of setting up request message), program is opened one and is about to be given the reception descriptor rd4 of server use fully, to response message of request message loopback.The request message that comprises rd4 is delivered to and is given server (for example EAGLE) fully, utilizes the reception descriptor rd2 of word 210 in the server database to go to visit and gives the webserver of server computer fully.One section sufficiently long giving of program block 706 waits is fixed time, to receive from giving the response message of server fully.The technology that produces this wait link is well-known, and it is by system and different.When receiving response, perhaps give the fixed time through one section, though which generation earlier, with regard to executing block 708.The result of program block 708 decision request messages.If server computer does not respond, perhaps Xiang Ying answer is "No" (representing that it can not be used as the server of this computing machine), then by program block 701 relevant " requisition " sign is resetted.Otherwise program block 712 will be taken over flag set for use, the availability of record server computer.No matter which kind of situation, loop program continues other an article or item in a contract in the processing server database.
" accepting request " program 800 of Fig. 8 shows the program step of carrying out when a computing machine responds the request message of another computing machine.This response is simpler.The name of requesting computer obtains from the message of receiving, and is made an explanation by " requisition " sign in the relevant an article or item in a contract in 801 pairs of customer data bases of program block.If flag set represents that this computing machine can be used as the server of requesting computer, then program block 802 produces and sends a sure response message to computing machine.Otherwise program block 804 produces and sends a negative response message.This response message is transmitted back to RAVEN, in this example, is by opening a transmission descriptor (for example Sd3) and this message being delivered to the reception descriptor (for example rd4) that receives realize in request message.
" connection " program 900 of Fig. 9 was carried out when being computing machines by computer administrator's request." connection " program is set up a communication channel that leads to the teleprocessing server for every network computer of login " requisition " flag set in server data.This communication channel is used for transmitting later teleprocessing request to computing machine.Figure 14 further illustrates this and how to finish, and supposes that here RAVEN is a computing machine of carrying out " connection " program, and EAGLE is a network computer in the RAVEN server database.Program block 901 among Fig. 9 is the loop program initialization, makes it can handle whole an article or item in a contracts in the RAVEN server database." requisition " of first computing machine sign is made an explanation by program block 902 in the database.If sign does not have set, then do not consider this an article or item in a contract, then handle next an article or item in a contract.If flag set, and to establish this computing machine be EAGLE, then program block 904 is opened one and is received descriptor (for example rd4), sets up and sends the message that connects that comprises password and rd4 to EAGLE.Consult Figure 14, connect message and deliver to the transmission descriptor rd2 that from the word 210 of server database, obtains, remove to visit the webserver among the EAGLE.Program block 906 is waited for the response of EAGLE in mode commonly used.
Figure 10 shows " receive and connect " program of carrying out when the EAGLE response connects message.Make an explanation corresponding to " requisition " in an article or item in a contract of RAVEN sign 108 in 1001 pairs of customer data bases of program block.If it does not have set, expression EAGLE now can't return a negative answer message at program block 1002 as the server of RAVEN.This response is to send by the reception descriptor rd4 in the original connection message, as shown in figure 14.If EAGLE can become the server of RAVEN, then the password in the word 102 is compared in the password that comprises in program block 1004 will the message from RAVEN and the EAGLE customer data base, and connecting message with checking is not from the user who acts as fraudulent substitute for a person.If password is inconsistent, then return a negative response at program block 1002.Otherwise program block 1004 is opened another and is received descriptor (for example rd3), and sends a positive response message that comprises rd3 by rd4 to RAVEN.As shown in figure 14, receive descriptor rd3 a communication channel that leads to EAGLE medium-long range processing server is provided.
Return " connection " program among Fig. 9, program block 908 determines that the responses from EAGLE are certainly or negative, perhaps gives not response after the fixed time through one section.If receive negative response or not response, then do not consider this server (EAGLE); Continue next an article or item in a contract in the processing server database at program block 901.If receive sure response from RAVEN, then program block 910 keeps in the RAVEN server databases an article or item in a contract corresponding to EAGLE by the reception descriptor in the word 212.Proceed to handle at program block 901.After, receive user's request as RAVEN, perhaps be subjected to when EAGLE sends the request of process of teleprocessing request message, being used for directly and teleprocessing server 1104 communications in the EAGLE corresponding to the rd3 in an article or item in a contract of EAGLE in the RAVEN server database.This point can be illustrated that the arbitrated procedure 1500 of RAVEN is opened one and sent descriptor Sd4 in Figure 15 by Figure 15, and sends a teleprocessing message (patent in above-mentioned co-applications is mentioned) to the teleprocessing server of EAGLE.
By mentioned above principle, be not difficult the present invention is done some improvement. For instance, a computer can stipulate in requisition message that it can be by the time limit of user as server. Can guarantee time synchronized between server and the user to available time limit of instruction manual server. Like this, although the absolute time that can use for server, user's view is different from server, and with respect to local clock, both are consistent for the view of absolute time. Arrived the time limit of regulation, the time-out process of giving in the standby server can stop to take over for use message to user's transmission.
Be not difficult to know that such scheme only is used for illustrating the application of the principles of the present invention, the technical staff can propose other scheme under the prerequisite that does not depart from thought of the present invention and scope.
