Description
Technical field
The present invention relates to distributed resource management, relate in particular to a kind of system and method for distributed resource management of dynamically self-adaptive.
Background technology
In a modern Distributed Computer System, different CPU veneers is realized different functions, realizes that by sharing out the work and helping one another of these veneers the designer designs the purpose of the function of whole system.Such as a telecommunication system that numerous users are arranged, the part veneer provides the resource disposal ability, abbreviate this resource disposable plates as resource board (RSB) for sake of convenience with certain function of realization, the part veneer is used for monitoring, distribution and management resource plate, this class veneer is called as resource management plate (RMB), comprise monitoring resource module and resource management module among the RMB, can also comprise resource use module.The overall situation that realizes RSB plate resource by RMB is shared.
Shown in Figure 1 is a kind of schematic network structure of distributed resource, comprises a plurality of RMB and RSB.Each RMB disposes the RSB veneer that number does not wait, and the state of these RSB veneers is monitored by the monitoring resource module among the RMB, also the RMB of monitoring RSB is called RMB under this RSB in the literary composition.Describe this corresponding relation with solid line among the figure, specifically monitor by the monitoring resource module among the RMB1 such as the state of resource board RSB11～RSB1p; The state of RSB21～RSB1k is monitored by the monitoring resource module among the RMB2.When resource uses module to use resource need to resource management module file an application, resource management module can distribute the RSB of other RMB monitoring for it, with dashed lines is described resource and is used relation among Fig. 1, and the RMB that uses this RSB resource as can be seen may not be the RMB of this RSB of monitoring.
How to realize that the overall situation of these RSB veneer resources shares, be to consider the problem that solves in the industry always, and the management to resource in the past mainly contains following several way to manage.
First kind of mode: each RMB only manages one's own resource, just monitors and manage unification.The problem that this mode exists is that resource can not be shared, and when the resource of certain MB all can not have been worked, although other RMB has idle resource, can not satisfy when RMB needs resource.Under this management mode, in order to guarantee that reliability need dispose more RSB plate and back up, the hardware cost of beginning increases, and also is unfavorable for later maintenance.
The second way: adopting the centralized resource management mode, is that 96117990.2 the disclosed scheme of patent (publication number is CN1156362A) is exactly a representative of centralized resource management as number of patent application.This scheme is placed on all resources on the RMB carries out unified management, and other RMB need resource must arrive upward application of this RMB.In case the problem that the method exists is the RMB of the unified centralized management resource machine of delaying, whole system just will be the situation appearance of paralysis office so, and will be abnormally dangerous.There is straddle message in resource bid between RMB in addition, unavoidably can cause applying for the long of resource time and the danger of losing message is arranged.
The third mode: resource is not managed concentratedly on a RMB, adopts distributed management yet, when not enough or resource goes wrong in the resource of a RMB, successively to other RMB application resource.The problem that this method exists is to have uncertainty, and the software flow complexity is difficult to realize.And time uncertain of application resource, the long time that has of the time that has is short, is unfavorable for that RMB goes up the software design of application resource part.
Below be that example describes above-mentioned the third distributive resource managing method in detail just with DTMF (Dual Tone Multi-Frequency, multisound and double-frequency) resource.The resource of DTMF is a kind of resource that needs in order to realize the conversation between a fixed telephone subscriber and other users in telecommunication apparatus.
Two empty frames among Fig. 2 are represented two RMB respectively, the call processing module of left side RMB1 (being that resource is used module) sends the request of application DTMF resource to resource management module, resource management module is checked to have earlier on this RMB does not have available DTMF, if find to have available, just apply now and take, and the numbering of the DTMF that takies is returned to call processing module; When this RMB had not had available DTMF, resource management module was just sent out the resource request of using of straddle to other RMB, as the RMB2 on right side.After RMB2 receives this request, also on this RMB, search earlier, do not use resource request if there is available DTMF resource just to send out to next RMB again, and the like, return or all RMB are asked one time up to applying for available DTMF resource and take.
Very loaded down with trivial details of this handling process, call processing module (resource use module) owing to be difficult to need to determine this straddle of how many times to call thereby also just be difficult to determine time of overtime protection, just very difficult choice thes processing in.In addition owing to exist straddle repeatedly to call, call processing module does not know that the information drop-out between plate still is the delay that straddle calls this normal handling flow process, consider that call treatment each time is free restriction, so may occur that although available resource is arranged, but since can not be too much inferior straddle call and cause call failure, cause call loss.For fear of the appearance of this situation, generally be to adopt to evade for the more resource backup plate of each RMB configuration, cause the rising of hardware cost like this.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of distributed resource management system and method for dynamically self-adaptive, when realizing sharing global resource, has simplified the processing of resource bid greatly, has shortened the time of resource bid.

Preferred forms of the present invention
Below in conjunction with the drawings and specific embodiments the present invention is further described.
The network configuration of the distributed resource management system of present embodiment is identical with Fig. 1, comprises monitoring resource module, resource management module and resource use module among the every RMB, wherein:
The monitoring resource module, be used for monitoring constantly and notify the resource management module of this RMB to make amendment when state variation for the firm and hard state of resources of RSB of its place RMB configuration, these states comprise, and whether: RSB is on the throne, whether can normally move, whether the real resource on the RSB has damage etc.
Resource is used module, is used for the resource management module application resource on this RMB.
Resource management module, be used for the real resource status of minute book RMB monitoring and the available real resource information that each RMB plate was also regularly obtained and write down to operating position, for the empty resource of this RMB configuration is sought available real resource and for both set up mapping relations, and when receiving resource bid, distribute available empty resource and return corresponding real resource number.It further comprises with lower unit:
The resource information memory cell is used to preserve real resource table, empty resource table and global shared resource table.
Real resource table, write down each real resource of this RMB monitoring numbering, state, use the RMB numbering contents such as (can be default when using) of this reality resource for this RMB.Real resource identifies with numbering, and each RSB plate is compiled one number, when a plurality of real resource example is provided on the RSB plate, also distributes a numbering for real resource example, just can uniquely determine it is which real resource example on which RSB plate by numbering like this.
Empty resource table has write down numbering, the mapping sign of each empty resource of this RMB configuration and the real resource number that has shone upon.The empty resource of RMB can be configured as required, and what just needing, what just dispose, and configuration can realize by manual mode or logon mode.
The global shared resource table, numbering and monitoring resource type and the available real resource quantity of this RMB and other RMB in the system have been write down, available real resource is normal operation and does not set up mapping relations with empty resource in the table, the real resource that can be used by all RMB.
Shared resource maintenance of information unit, be used for regularly after other RMB transmissions are obtained the message of global shared resource or received this message, returning real resource quantity and the type that this RMB can use, realize the timing of global shared resource table is upgraded according to the information of obtaining from other RMB, mapping and when also having available real resource in this RMB finishes plate simultaneously adds global resource sharing tables in order to inquiry with these available real resources.Like this, on RMB, realized the fast mapping of empty resource and real resource.
Processing unit is set up in mapping, is used to the empty resource of this RMB configuration to seek available similar real resource and set up both mapping relations.Comprise:
Subelement is set up in mapping in the plate, be used for also not setting up the empty resource of mapping, in the real resource table of this RMB, seek the available real resource of same type, then should the reality state of resources be changed to the numbering of shining upon and in the record of this void resource, filling out this reality resource.
Subelement is set up in mapping between plate, be used for when this RMB does not have available real resource, search the global shared resource table and seek upward available real resource of other RMB, find the back to send request to this RMB, obtain confirming that the back fills out the numbering of this reality resource in the record of this void resource, delete the record of this reality resource correspondence or put it when receiving the message that refusal uses for invalid.
Subelement is confirmed in mapping between plate, be used for receive that other RMB sends use the request of real resource the time, judge the current state of these real resources, but return acknowledge message in the time spent, and these real state of resources are changed to shine upon, otherwise return the message that refusal is used.
Resource allocation unit, be used for when receiving resource bid, for it distributes available empty resource (empty resource only is only available) after shining upon with real resource, and return the real resource number of this void resource correspondence that obtains by empty resource table, if there is not available empty resource just to return failed message.
The resource management control unit is used for each unit is coordinated and controlled, and finishes the adaptive management to distributed resource, further comprises:
The control sub unit that powers on is used for after system powers on, and a timer is set normally moves with RSB under waiting for this RMB, and start the process of obtaining global shared resource, starts the process that mapping is set up behind timer expiry.
Real change in resources is handled subelement, be used in real a resource shrinkage or when receiving the notice that real resource that other RMB sends can not normally move, should be changed to unavailable by the reality resource status, when this reality resource has been shone upon, also notice uses the RMB of this reality resource to remove its empty resource and this reality resource mapping relation, and attempts setting up new mapping for this void resource.When available real resource increases, these real state of resources are changed to available, set up and these real resource mapping for shining upon similar empty resource on this RMB, and available real resource adding global shared resource table that will be unnecessary.
Empty change in resources is handled subelement, is used for attempting being the mapping relations between its foundation and real resource when the empty resource of configuration increases.When the empty a resource shrinkage of configuration, remove the existing mapping relations of this void resource (if any), this void resource of deletion from empty resource table, the real resource of former mapping is when this RMB, be changed to its state available and adding global shared resource table, this reality resource notifies its RMB to be changed to its state available not when this RMB.
Based on the system of above distributed resource management, before system operation, need all real resources of configuration earlier and the empty resource of every RMB needs, for these resource numbers and write among the subordinate RM B in separately the tabulation.Present embodiment is supposed the empty resource of available real resource more than configuration.
After system powered on, the flow process that RMB1 finishes initial resource mapping may further comprise the steps:
Step 1, RMB1 powers on after the success, at first send out the event message that obtains global shared resource so that obtain the respective record of other RMB in the global shared resource table to the monitoring module of other RMB, a delay timer (Ti is set simultaneously, i can set arbitrarily according to the programming needs), wait for the normal operation of the RSB plate of the monitoring module monitoring on the RMB1;
Step 2, before the timer on RMB1 (Ti) is overtime, when the monitoring module of RMB1 find the RSB of own monitoring normally move the back with regard to the flag bit (perhaps being mode bit) in the real resource table in this RSB correspondence immediately mid-available sign;
Before the time exceeded message of delay timer (Ti) arrived, RMB1 had following two kinds of processing methods when other RMB sent out the event message that obtains global shared resource to RMB1: 1) do not respond; 2) respond requestor RMB1 temporary no available shared resource in the global shared resource table.Two kinds of methods can be chosen any one kind of them, and purpose is to guarantee that other RMB have the available resource information of RMB1 in can the global shared resource table at them before the timer (Ti) of RMB1 is overtime.
Step 3, after RMB1 receives the overtime incident of oneself timer (Ti), from empty resource table, find the empty resource of also not shining upon successively with real resource, to find mode bit then from real resource table be upstate and be the real resource of same type, fill out the numbering of this reality resource in then should the record of void resource in empty resource table, and the state of this real state of resources position is set to shine upon in real resource table, thereby realizes the empty resource mapping of the RSB resource of RMB1 monitoring with RMB1;
Step 4 judges whether all empty resources of RMB1 configuration have all had real resource to shine upon with it, if, execution in step five, otherwise, execution in step six;
Step 5 checks that whether also having mode bit on the RMB1 is the real resource of available flag, if there are all the available real resources that just will be left to put into global shared resource table on the RMB1, waits for that other RMB regularly obtain corresponding information, end;
Step 6 at this moment, also has empty resource not shine upon on the RMB1, and the RSB of RMB1 monitoring has not had available, then searches the available real resource whether other RMB also has same type from the global shared resource table of RMB1, if having, execution in step seven, otherwise, execution in step 11;
Step 7, RMB1 sends to other RMB (being assumed to RMB2) of this reality resource of monitoring and uses real resource request message;
Step 8, after RMB2 receives and uses real resource request message, whether judge currently really has real resource to use, if, execution in step nine, otherwise, return failed message, the record deletion that RMB1 is should the reality resource relevant (or be changed to invalid) returns step 6 then, promptly seeks other available real resource in the global shared resource table;
Step 9, RMB2 determines to set up the real resource of mapping with this void resource, and in real resource table, these real state of resources are changed to and shine upon, and the numbering of the RMB1 that uses of record, return the affirmation message that allows to use real resource to RMB1 then, and the real resource number of using is provided;
Step 10 after RMB1 receives the response message of using real resource, is set up empty resource and the real resource mapping relation of using, and finishes;
Step 11 at this moment, also has empty resource to can not find corresponding real resource, and then the notifying operation operator on duty handles.
As can be seen, complicated and uncertain for fear of flow process, the resource of above flow process preferred this RMB monitoring when the empty resource on the RMB being carried out the resource mapping, particularly under situation about just having powered on, RMB need wait for that a bit of time confirms the resource successful operation of this RMB monitoring, just allows the resource of the free time that other RMB of mapping monitor under the situation that the resource of this RMB monitoring still can not be moved in the time of waiting for.
In system's stable operation (after referring to finish the flow process of above-mentioned preliminary mapping), need carry out the maintenance of global shared resource table and carry out resource allocation.In addition, increase or reduce, and the configuration of empty resource also needs both mapping relations are handled when increasing or reducing in real resource.
The maintenance of global shared resource table
In order to safeguard that each RMB goes up the global shared resource table, realize refreshing in real time, RMB just sets a timer after finishing powering on after other RMB (can know total what RMB according to configuration) obtain the required information of global shared resource table the first time, regularly send out and obtain global resource table request message to other RMB, other RMB plates return the type and the quantity of the available real resource of this board monitoring, this RMB fills in the global shared resource table according to these information again, comprises the fields such as quantity of numbering, resource class and the available real resource of the RMB with monitoring module.
Can also realize the renewal of global shared resource table data by other multiple mode, as: regularly broadcast real resource information available on this module by resource management module to other modules.
Processing during the reality a resource shrinkage
In system when operation,, the running status of RSB under the monitoring module of RMB is being monitored constantly supposes that RMB1 detects the RSB or the real resource example of the part on the RSB cisco unity malfunction of this RMB monitoring, when causing real a resource shrinkage, carries out following handling process:
Steps A, RMB1 indicates down state with real resource example corresponding mode bit in real resource table of all cisco unity malfunctions;
Step B, RMB1 search local real resource table, judge whether this reality resource has mapping relations with empty resource, if do not have, directly finish, otherwise carry out next step;
Step C, RMB1 judges RMB this RMB whether that uses this reality resource according to the record of real resource table, if, directly remove its empty resource and this reality resource mapping relation, promptly delete this reality resource number in the RMB1 void resource table respective record, carry out next step; If not the real resource of this RMB monitoring, notice is used the RMB of this reality resource immediately, after this RMB is notified, with this real resource example and empty resource mapping relation broken in the empty resource table, carries out next step immediately;
Step e uses the RMB of this reality resource to check whether have resource to use module to take this void resource, if having, notifies this resource to use module to be correspondingly processed immediately, carries out next step, otherwise, directly carry out next step;
Step F, the RMB that uses this reality resource seeks available real resource in this locality for this void resource and sets up mapping relations, if do not find, six attempts setting up this void resource to the method for step 11 and concerns with the RSB resource mapping of other RMB monitoring set by step again.
If reducing, the RSB plate causes real a resource shrinkage, can be in the steps A directly from should the reality resource from real resource table, deleting.
Processing when available real resource increases
When system moves, suppose that the RSB that RMB1 detects this RMB monitoring has the veneer or the real resource example that can normally move again, such as, the abnormal operation of the RSB of this RMB monitoring before timer (Ti) is overtime, and this RSB starts operation in the overtime back of timer (Ti), cause available real resource to increase, carry out following handling process:
Step H, RMB1 are changed to these real state of resources available in real resource table;
Whether step I, RMB1 check the empty resource of also not setting up the same type of mapping with real resource in the empty resource table, if having, and execution in step J, otherwise, execution in step K;
Step J, RMB1 set up the mapping relations between this void resource and newly-increased real resource, if also have unnecessary newly-increased real resource, carry out next step again, otherwise, finish;
Step K is put into the global shared resource table of this RMB with unmapped newly-increased real resource also, waits for that corresponding information is obtained in the timing of other RMB.
Processing when the empty resource of configuration increases
When system moved, the empty resource that is assumed to the RMB1 configuration increased, and then at first searches whether available real resource is arranged in this firm and hard resource table by following flow processing: RMB1, if having, sets up both mapping relations; If do not have available real resource or also have the empty resource of part not set up mapping, then six attempt setting up this void resource to the method for step 11 and concern set by step with the RSB resource mapping of other RMB monitoring.
Processing during the empty a resource shrinkage of configuration
When system moves, be assumed to the empty a resource shrinkage of RMB1 configuration, then directly remove this void resource with original real resource mapping relation by following flow processing: RMB1, in empty resource table, delete this void resource then, if this original real resource is local real resource, then directly its state is changed into available, if the real resource of other RMB monitoring, then notify this RMB, should original real state of resources change into available by this RMB.
The flow process of application resource
Fig. 3 is that present embodiment adopts the resource bid flow process under the resource management mode of empty resource.The resource management module of RMB is only managed the empty resource of this RMB, like this resource use module (as call processing module) on this RMB when resource management module application resource, what apply for is available empty resource (empty resource only is only available after shining upon with real resource), resource management module judges that whether this RMB just has available empty resource, if no, use module to return failed message to resource.If have, be that it distributes an empty resource, and obtain the numbering of unique real resource of this void resource correspondence by empty resource table, return to resource and use module.
Therefore, the automatic maintenance of present embodiment by mapping relations borrowed resource with regard to what do not need to carry out straddle, and so each resource uses the time of module application resource to fix, and is very quick.And resource uses the handling process of module to simplify greatly, has improved efficient.
Describe the method for the foregoing description in detail below by an application example.
Shown in Figure 4 is to concern with empty resource of example and real resource mapping.Have the DTMF resource of 10 realities now, be numbered DTMF1～DTMF10 respectively, 3 resource management plate RMB, be numbered RMB1～RMB3, each resource management plate RMB disposes 3 empty DTMF resources, and wherein the monitoring module of RMB1 has disposed 2 real resources (DTMF1 and DTMF2), and the monitoring module of RMB2 has disposed 4 real resources (DTMF3～DTMF6), the monitoring module of RMB3 has disposed 4 real resources (DTMF7～DTMF10), indicated this configuration relation as the solid line among Fig. 4.
Regular by appointment: the resource of preferred this RMB monitoring when carrying out the resource mapping of the empty resource on the monitoring RMB, under all veneers all normally power on ruuning situation, RMB1, RMB2 and RMB3 start, real resource DTMF1～DTMF10 also normally starts, empty DTMF resource and the real resource DTMF3～DTMF5 of RMB2 shine upon one by one so, in like manner empty DTMF resource and the real resource DTMF7～DTMF9 of RMB3 shine upon one by one, shown in the dotted line among Fig. 4; The real DTMF6 that supposes RMB2 also is in upstate, and the real DTMF10 of RMB3 monitoring also is in upstate.3 empty DTMF resources of RMB1 configuration are at first shone upon with real resource DTMF1 and the DTMF2 that this RMB monitors, and still have an empty DTMF3 resource not shine upon, and can only be empty temporarily, and empty DTMF3 resource is unavailable.
Because powering at first to send out to other RMB after the success, RMB1 obtains global resource table request message to obtain the corresponding record of global shared resource table, so have such two records in the global shared resource table on RMB1, be that RMB2 has an available real resource DTMF6, an available real resource DTMF10 is arranged on the RMB3.In order to safeguard that each RMB goes up refreshing of global shared resource table, RMB obtains and just sets a timer after the global shared resource table writes down accordingly from other RMB (can know total what RMB according to configuration) after finishing powering on the first time, regularly send out and obtain global resource table request message and remove to obtain other RMB global shared resource tables to other RMB, see Fig. 5, just RMB1 sends out to RMB2 and RMB3 and obtains global resource table request message, the information of RMB2 in the global shared resource table and RMB3 correspondence is got access to RMB1, the information that same RMB2 also obtains from RMB1 and RMB3 is inserted the global shared resource table on this plate, and the information that RMB3 also obtains from RMB1 and RMB2 is inserted the global shared resource table on this plate.
Shown in Figure 6, when finding RMB2 from the global shared resource table, RMB1 have available real resource DTMF6 and RMB3 that available real resource DTMF10 is arranged, suppose that RMB1 sends out to RMB2 earlier and use real resource request message, after RMB2 receives and uses real resource request message, whether the real DTMF resource that just scans this RMB monitoring is really to have more than needed and do not used by other RMB, found that DTMF6 can use, managed by RMB1 so just on the resource of DTMF6, indicate, return the response message of using real resource to RMB1 then, RMB1 receives the mapping relations of finishing empty resource DTMF3 and real resource DTMF6 after the response message of using real resource.
The DTMF6 cisco unity malfunction that the RMB2 discovery is monitored oneself in the process of operation, so RMB2 finds that from the DTMF resource DTMF6 is managed by RMB1, so notify RMB1 to say that DTMF6 is unavailable immediately, RMB1 removes the mapping relations between empty DTMF resource and DTMF6 after receiving message immediately, and check whether have call processing module to take, if have, just notify the corresponding call processing module to be correspondingly processed immediately; In the global shared resource table, checking whether available DTMF has been arranged then, if have, then repeat the flow process of Fig. 5, can not come the notifying operation operator on duty by alarms such as sound, light if having, expression has empty resource not have real resource correspondence, and the operator on duty intervenes processing by operation.Such as replacing inoperable RSB or disposing new RSB, deal with problems in advance, rather than resource is genuine by the time just alarms when unavailable, guarantee the reliability of system.
Second embodiment
First embodiment is in the real resource of the whole system configuration empty resource more than configuration, and the real resource of configuration is all under the condition of operate as normal, and its handling process can guarantee the reliability service of system fully.But real resource in the unnecessary configuration of empty resource of disposing, perhaps there is too many real resource not work, when causing workable real resource to be less than the empty resource of configuration, use uneven as resource, the empty resource that can occur on some RMB is lower because of utilization rate, cause the real resource of shining upon occupied and need not, other RMB goes up and does not cause empty resource unavailable because of empty resource is mapped to real resource, and then causes resource to use module to apply for occurring less than the situation of resource under the situation that has real resource not to be used.
In order to overcome this situation, present embodiment has proposed a kind of mechanism of complete dynamic self-adapting on the basis of the first embodiment method and system, promptly dynamically adjusts mapping relations according to the utilization rate of empty resource under the system stable operation situation.In resource management module, increase a mapping relations adjustment unit, be used to carry out following processing: a timer Tj (timing can be set arbitrarily according to the programming needs) is set behind the system stable operation of RMB veneer, timer Tj is timed to, check the utilization rate of the empty resource of this RMB, if the utilization rate of certain empty resource is lower than certain set point, just should void resource and real resource mapping relation broken, release is temporarily accounted for by this RMB and the real resource of usefulness not, its state is changed to available, and doses in this table by the timing of global shared resource table is upgraded; If the utilization rate of certain empty resource is greater than set point and do not set up mapping with real resource, then seeks available real resource for it again and set up mapping relations, to increase the quantity of available empty resource.The mode of this dynamic self-adapting is only just enabled under workable real resource is less than the situation of empty resource of configuration, there is no need to enable under the normal condition.
In sum, adopt the resource management mode of the empty resource of utilization provided by the invention, owing to adaptive handling process is arranged, and is in non-call flow, to realize automatic empty resource and real resource mapping, call resource and cause call loss with regard to the repeatedly straddle that the previous example appearance can not occur.
