Further as shown in figure 1, apparatus of the present invention include：Configuration module, enquiry module, detection module, update module with
And output module.Wherein, configuration module and enquiry module are arranged at the foreground of software program, for being interacted simultaneously with keeper
The instruction that keeper sets is handed down to detection module, update module and the output module on backstage；Detection module, update module
And output module is then arranged at the backstage of software program, the finger sent according to foreground configuration module, enquiry module is respectively used to
Order carries out the detection of IP address accessibility, the renewal of free IP addresses data and the output of free IP addresses data.In the present invention,
Described device reads by CPU and instructs during realizing that free IP addresses are detected, each intermodule interaction flow is specifically as schemed
Shown in 2：
Step 1, configuration module receive the instruction of the startup detection free IP addresses of keeper's setting, and after sending it to
Detection module, update module and output module in platform program.
Specifically, when keeper determines to start free IP addresses detection function, then network manager is needed by configuring mould
Block setting starts the instruction of detection free IP addresses.At the same time, in order to realize the detection to free IP addresses, keeper also needs
The parameter instruction of other detection free IP addresses is further set by configuration module.For example：IP address accessible detecting
Cycle（Can be in units of hour, span is 1-12, and wherein detection cycle is smaller, that is, IP address accessible detecting
Granularity is smaller, and detection free IP addresses can be more accurate）, the free IP addresses data update cycle and when keeper send close inspection
After surveying the instruction of free IP addresses, if continue the configuration parameters such as the record of free IP addresses in retention data storehouse.
In the present invention, the free IP addresses data update cycle should be greater than be equal to the IP address accessible detecting cycle.It is preferred that
Ground, the free IP addresses data update cycle is some integral multiples in IP address accessible detecting cycle.
When network manager completes above-mentioned parameter with postponing, the configuration module is further by the order parameter of above-mentioned configuration
It is sent respectively to detection module in background program, update module and output module.
After step 2, detection module receive the instruction of startup detection free IP addresses of configuration module transmission, according to management
Whether the IP address accessible detecting cycle detection IP address of member's setting is reachable, if it is, by reachable IP address
IP address be recorded up in list, if it is not, then inaccessible IP address recorded in the unreachable list of IP address.
Specifically, when backstage detection module receives the instruction of the startup detection free IP addresses that foreground configuration module sends
When, the detection module can start one according to keeper by the IP address accessible detecting cycle that foreground configuration module is set
Corresponding detection timer, so as to detection module according to keeper's customized cycle come cycle detection NM server institute
The IP address reachable state of management.
It should be noted that in the present invention, when detection module is examined for the first time within the free IP addresses data update cycle
Survey IP address whether up to when, the state of reachability that detection module needs give tacit consent to all allocated IP address be it is unreachable, with
Ensure within the free IP addresses data update cycle, whether each IP address is reachable to be at least detected once.In addition, when detection mould
Block has been distributed after IP address accessible detecting finishes all, and the reachable IP address of all detections recorded up to IP address row
In table, all inaccessible IP address recorded in unreachable IP address list.If now free IP addresses data update
Cycle not yet reaches, then, when next detection cycle arrives, detection module only can be to those at upper one week for the detection module
Inaccessible IP address is detected again during detection in phase, then remembers the reachable IP address of all detections in the detection cycle
Record up in IP address list, inaccessible IP address recorded in unreachable IP address list.Go round and begin again, until idle
Untill when the IP address data update cycle reaches.
Step 3, when reaching the free IP addresses data update cycle, update module is entered to the free IP addresses in database
Row updates.
In order to realize the object of the invention, in realization of the invention, except enabling the IP address accessibility inspection described in step 2
Survey outside corresponding timer, further, the detection module also enables one with the free IP addresses data update cycle simultaneously
Corresponding data update timer, so that when reaching the free IP addresses data update cycle, detection module can be remembered in time
The all of record are sent to update module up to IP address and unreachable IP address information, so that update module is in database
Free IP addresses data are updated.
After update module receives all reachable IP address and unreachable IP address of detection module transmission, in database
Free IP addresses be updated.Specially：When update module receives all up to IP address and not of detection module transmission
Up to after IP address, the free IP addresses in further reading database will be within the free IP addresses data update cycle through inspection
Survey reachable free IP addresses to be deleted from database, while will not exist in database but update week in free IP addresses data
During the inaccessible IP address of detection increases to database in phase, and it is existing in database but in free IP addresses data more
The inaccessible IP address of detection in the new cycle, then update the data free IP addresses in storehouse according to the free IP addresses data update cycle
Idle number of days.
By after the interaction of above steps intermodule, the present invention can realize the permanently effective inspection to free IP addresses
Survey, and the accessible detecting according to IP address have recorded the long-term distribution free IP addresses not used simultaneously.
Further describe keeper is how to complete inquiry to these free IP addresses, release and divide again below
Match somebody with somebody, and then increase IP address resource utilization.
The query statement of the free IP addresses that step 4, enquiry module set according to keeper, query statement is sent to defeated
Go out module, free IP addresses in the output module reading database, and the free IP addresses of inquiry content will be met to feed back to
Enquiry module.
Specifically, when the free IP addresses that keeper needs inquiry to distribute, it is by looking into that foreground program is set
Ask module and set specific query statement.Wherein described query statement can every time manually enter completion by keeper, and certain has
The inquiry of qualified free IP addresses in body IP address or IP address section, it is also possible to by network manager according to predetermined
Strategy setting is inquired about into automatic.For example：When keeper's query statement automatic according to predetermined strategy setting, can be according to fixed week
Phase（For example with " moon " for unit）Or the idle number of days of the IP address of free time completes automatic inquiry more than or equal to a certain threshold value etc.
And output.
When enquiry module receive keeper manually enter or set automatic query statement after, send it to output mould
Block.The output module meets query statement content according to the input or the automatic query statement of setting in reading database
Free IP addresses, and it is exported to the enquiry module on foreground, discharged for keeper and redistributed, and will release and
The free IP addresses redistributed are deleted from database, and then increase the resource utilization of free IP addresses.
In addition, detecting free time IP ground by the closing that foreground configuration module sets when backstage detection module receives keeper
During the instruction of location, idle IP detection timers can be stopped and free IP addresses data update timer, while being set according to user
The fixed parameter instruction for whether retaining historical record decide whether delete database in record free IP addresses data.
In order that those skilled in the art are more clear and clear, below in conjunction with the exemplary application of the present invention shown in Fig. 3
Scene describes the present invention in detail.
Assuming that under certain application scenarios, 250 IP address have been assigned with certain network, network segment interval is：10.153.89.1
~10.153.89.250, records 10.153.89.131~10.153.89.250 this 120 in the database of NM server
IP address free time number of days is 10 days, does not have remaining IP address free message.
It is further assumed that under the application scenarios, it is 12 hours to set the IP address accessible detecting cycle, that is, every 12
Hour, detection module re-starts accessible detecting to inaccessible IP address in a upper detection cycle.And set each IP
The address unreachable time limit is 3 seconds, that is, if detection module receives the reachable response message of IP address in 3 seconds, depending on the IP
Address up to and by renewals in reachable IP address list, whereas if not received also more than 3 seconds after an IP address transmission
The corresponding response message of the IP address, then it is unreachable regarding the IP address, by renewal in unreachable IP address list, wherein not
It is 1 second up to the frequency that IP address updates, i.e., inaccessible IP address is updated once every 1 second；Free IP addresses data are more
The new cycle is one day, and the time that data update is the 23 of the same day:59:59 seconds.
ICMP is sent with detection module below（Internet Control Message Protocol, Internet controls
Message protocol）The detection intraday accessibility of IP address and idle number of days situation of change are illustrated as a example by message.
Before the daily first time detection cycle of detection module startup starts, specific implementation of the invention, meeting
It is unreachable to give tacit consent to the state of reachability on the day of all allocated IP address.When first detection cycle of arrival（It is assumed to be 0:
0:0 second）Afterwards, 250 IP address to be detected in foregoing network segment interval can be write non-transmission list by the detection module
In ListA, then, the detection module can construct icmp packet, and 10.153.89.1~10.153.89.100 is sent for the first time
Individual message（The value can arbitrarily be set by keeper）, while this 100 IP address for having sent are transferred into internal memory having sent
In list ListB, and record this 100 IP address for having sent and send the time accordingly.After first time sends, do not send
150 IP address are there remains in list ListA.
In view of the pressure of aspect of performance, in the exemplary application scenarios of the invention, preceding 100 IP ground is being sent
Behind location, the ICMP response messages of the IP address of the transmission can be received, and set a length of 100 milliseconds during reception, if this 100
Receive several ICMP response messages in millisecond, then in internal memory reachable IP address list ListC to record these IP address reachable,
These IP address are deleted from transmission list ListB simultaneously, is then selected in remaining not detected IP address in ListA
Same number IP address continues construction icmp packet and is transmitted again, is completed until all of IP address is all detected.
With exemplary application scene of the present invention as an example it is assumed that detection module is in 100 milliseconds, have received altogether before this
10.153.89.1~the 10.153.89.10 of transmission this 10 response messages of IP address, then up to IP address list in internal memory
This 10 IP address are recorded in ListC reachable, while delete this 10 IP address from transmission list ListB, then followed by
It is continuous that 10 IP address are selected from ListA（Such as 10.153.89.101~10.153.89.110）Continue construction icmp packet to enter
Row sends, remaining 140 IP address in so subsequent non-transmission list ListA.Used because one cycle sends 100 IP address
Shi Keneng is no more than 1 second, has IP address in ListA and ListB during this period, and the ICMP that 100 milliseconds are at this moment received again should
Message is answered, if receive this 20 ICMP response messages of 10.153.89.11~10.153.89.30, then up to IP in internal memory
This 20 IP address of record 10.153.89.11~10.153.89.30 are reachable in address list ListC, and deleted from ListB
These IP address.Then 20 IP address of reselection from ListA（Such as 10.153.89.111~10.153.89.130）Structure
Make icmp packet to be transmitted, remaining 120 IP address in ListB.The like, until all of IP address has all been detected
Into.
Due to the application scenarios according to present invention setting, detection module can will update unreachable IP address list every 1 second
ListD is once.That is, overtime unreachable IP address is deleted from transmission list ListB, and it is transferred to unreachable IP ground
In location list ListD.Because the unreachable time-out time of IP address in this application scene, setting is 3 seconds, before institute twice not
Have any IP address time-out.When the IP address for sending still was not received by corresponding ICMP response messages more than 3 seconds, then
These overtime IP address are deleted from the IP address list ListB for having sent, and the overtime unreachable IP address is transferred to not
In up to IP address list ListD, it is assumed that have 10 IP address with current time difference more than or equal to 3 seconds in ListB, be
10.153.89.91~10.153.89.100, recording these IP address in the unreachable IP address list ListD in internal memory can not
Reach, and this 10 IP address are deleted from ListB, if now there is the IP address not detected in ListA, continue to construct 10
The icmp packet of individual IP address is transmitted detection.
When ListA and ListB are space-time, show that the IP reachability detection has detected completion in this detection cycle.
Assuming that the following 10.153.89.91~10.153.89.100 of testing result, 10.153.89.200~10.153.89.250 be not for
Reachable, remaining IP address is reachable.According to testing result, apparatus of the present invention update the data the number of days of IP address free time in storehouse, internal memory
And the IP address accessibility on the same day, there are following several situations：
When in internal memory up to IP address list ListC in record 10.153.89.1~10.153.89.90,
10.153.89.101~10.153.89.199 these IP address same day states are reachable, are remembered up in IP address list in internal memory
Record that these IP address free time number of days is 0 and same day state is reachable, detection module of the present invention is no longer during next accessible detecting
Detect these IP address.
When in unreachable IP address list ListD in internal memory record 10.153.89.91~10.153.89.100,
10.153.89.200~10.153.89.250 same day states are unreachable, and next accessible detecting continues to detect these IP ground
Location.When the next detection cycle of arrival（It is assumed to be 12:00:01 second）When, only to 10.153.89.91~10.153.89.100,
10.153.89.200~10.153.89.250 these IP address carry out accessible detecting.Then will be detected in the detection cycle
During reachable IP address recorded up to IP address list ListC, unreachable IP address be recorded into unreachable IP address list
In ListD.Go round and begin again, reached until the free IP addresses data update cycle.
Furthermore, it is contemplated that under some application scenarios, the software of individual plants can ignore the ICMP detections of IP address in network
Message, in the present invention, on the basis of icmp packet detection, further increases the ARP testing mechanisms of free IP addresses, has
Body is as follows：
After detection module is detected in the icmp packet for completing IP address, the further poll gateway within ARP digestion periods
In the network equipment, therefrom obtain equipment ARP information, if during unreachable list ListD is got in ARP information record
IP address, then the state on the day of the IP address from " unreachable " is revised as " reachable " and moves on to up to list ListC it
In.
When the free IP addresses data update cycle is reached, for example：23 are reached in this application scene：59：It is false at 59 seconds
If all unreachable in 10.153.89.90~10.153.89.95,10.153.89.230~10.153.89.250 mono- day.Then more
New module increases the idle number of days of these IP address 1 day, updates in free IP addresses database.Final result is
The idle number of days of 10.153.89.90~10.153.89.95 is 1 day, 10.153.89.230~10.153.89.250 free time days
Number is 11 days, and remaining IP address free time number of days is 0.It is interim over next day, all IP address same day reachable states are reset for not
It is reachable, start the IP address accessible detecting of new a day.
Compared with prior art compared with the present invention is by the permanently effective detection of IP address, recording what is do not used for a long time
IP address, so as to facilitate network manager to the release of these free IP addresses, redistribute, and then increases the IP address utilization of resources
Rate.
