Figure 10 is the schematic diagram of one embodiment of concrete application of the present invention.With a vBRAS equipment and an entity
Exemplified by BRAS equipment, vBRAS equipment passes through Netconf interfaces and Radius Interface and Controler pair respectively with entity B RAS equipment
Connect, controller is interconnected by the Restful interfaces of standard with explorer.
Firstly the need of the information that the address resource correlation for needing to manage is imported or configured in explorer, including：
(IPv4 refers to network address and mask, IPv6 by IPv4, IPv6 address block block name, id, prefix and prefix length
Refer to network prefix and prefix length) and its parameter such as corresponding gateway, DNS.Then need to configure global policies parameter, bag
Include：Equipment timing report cycle, alarm threshold thresholding, Tidle threshold thresholding, idle waiting cycle, equipment heart time, equipment
Sampling period etc..Finally need to add IP and the port of the controller of connection on explorer, and two of the second line of a couplet set
Standby IP address and port, and the domain name for needing well to configure according to planning and configuration for each equipment.
After explorer is according to the IP address of controller and port configuration connection controller, explorer can be by the overall situation
Parameter and the list of devices of controller management and the domain configuration distributings of 2 equipment can bases to controller, controller
The domain for being configured to every equipment applies for that resource is reserved to locally in available address.Such as：VBRAS device configurations pppoe
Domain, BRAS equipment is configured with ipoe domain, and it (can be IPv4 that controller respectively reserves 1 IP address resource for it
Address resource either IPv6 address resources, are pre-configured with according to the real needs of equipment in domain).
After equipment is reached the standard grade first, the parameter needed for equipment is handed down to equipment by controller first, is then distributed to equipment
The address resource of acquiescence, in the embodiment, controller can be handed down to one, the pppoe domains ippool1 of vBRAS equipment and with one section
The ipblock1 associations of acquiescence；One, the ipoe domains ippool2 for the BRAS equipment reached the standard grade is handed down to simultaneously and is given tacit consent to another section
Ipblock2 associations, the parameter such as gateway and DNS is also included in the configuration issued.After initial issue, two equipment are just
Can be that terminal user distributes service IP address.
Two equipment regularly report making for respective ipblock1, ipblock2 according to the timing report cycle time issued
With rate to controller, by controller report to explorer, explorer is according to belonging to the utilization rate of address block calculates it
Domain address resource utilization rate and be compared with threshold value, the utilization rate of address resource is less than door under normal circumstances
Threshold value is limited, the utilization rate information of explorer recording equipment simultaneously replys response message.
It is assumed that set threshold value be 80%, when vBRAS equipment reach the standard grade suddenly a large number of users distribution address, cause a certain
The address utilization rate that moment reports be 81% (equipment report be each ipblock utilization rate, explorer can be according to setting
Standby ipblock, ippool and domain corresponding relation, each domain of equipment address average service rate is calculated, with this
To be compared with threshold value, due to that may there is multiple ippool, an ippool to contain multiple in domain
Ipblock, single ipblock not necessarily cause domain threshold value to transfinite more than thresholding, pass through domain average use
The comparison of rate can more accurately distribute according to need address, avoid unnecessary new address resource from distributing), explorer passes through threshold
Value compares, it is found that exceeding thresholding triggers new address allocation flow, and has searched whether assignable free address block, confirms free
Not busy address block is then chosen ipblock3 and issued, and this is in when choosing new address block, it is necessary to ensure the address block newly issued
Gateway and DNS can associate matching with the ipblock1 issued gateway and DNS, that is to say ipblock1,
Ipblock3 can use a set of gateway and DNS, so just can guarantee that user can be normally carried out visiting after being assigned to IP address
Ask.If explorer can not find the address block with having issued matching, by the ipblock3 selected newly associations one
Ippool3 is issued in the pppoe domains of vBRAS equipment, and that realizes ipblock3 by way of newly establishing an ippool can
The property used.Ipblock3 is issued simultaneously, and explorer can will distribute address block and be marked and notify equipment, preferentially will
Ipblock1 address is allocated, and after ipblock1 effective address is all distributed, then is distributed since ipblock3,
So avoid after newly distributing address resource, the allocative efficiency of original resource reduces.
During BRAS equipment timing reports the utilization rate of address block, certain period is die-offed due to user's online demand
(such as school has a holiday or vacation), causing address utilization rate, (the idle waiting cycle now configured is in 5 timings within the idle waiting cycle
Report cycle time) always not higher than Tidle threshold (Tidle threshold 0), now explorer can start address and reclaim stream automatically
Journey, address recovery command is issued to BRAS equipment by controller according to recovery judgement flow, BRAS equipment is deleted after receiving instruction
Except business configurations such as the related route issues of the sector address block and ipblock2 configuration is deleted, passes through controller after reclaiming successfully
Receipts success message is fed back to explorer, explorer is received the status set " free time " of the address block after message,
Other equipment can be continued as to be allocated.
After controller receives the offline notice of equipment, feedback resources manager, explorer can be issued to all
The address resource of the equipment carries out pressure recovery, and all address resources, explorer renewal ground are discharged after the offline success of equipment
The status information of location block.
The UI interfaces of explorer, keeper can manually for certain equipment issue new address resource and
Reclaim some address resource.Issuing flow manually is：Some domain for the equipment that keeper's selection is specified, selection distribution
IPv4/IPv6 addresses, the ipblock address blocks of free time are then selected to be handed down to equipment, equipment is received the address after the message
The configuration of block increases in the address pool configuration of itself.Manual recovery process is：When keeper to certain section of designated equipment
When the address block of distribution is reclaimed, issue instant recovery command, after equipment receives instruction, first by the sector address block
Online terminal user kick it is offline, then will corresponding to the sector address block route etc. business configuration remove, then delete the address
Matching somebody with somebody for block postpones, and feedback controller reclaims successfully, controller notice explorer, and the address block status set is idle, complete
Into manual recovery process.
Equipment regularly can circulate a notice of KA heartbeat message with controller simultaneously, so that controller will appreciate that its equipment managed
Equipment state is forwarded to explorer write into Databasce by real-time status, controller；Simultaneously all controllers also can timing to
Explorer circulates a notice of KA heartbeat message, and explorer controls the status information of whole system all devices.
Wherein, in above-described embodiment, realize that the relevant interface parameter model that address block issues automatically can be based on YANG moulds
Type realizes, including：The related parameter of IPv4 to IPv6 address blocks, and the address pool of its association and domain association are closed
System, in addition to the parameter such as id of its corresponding equipment, ensure that the address block can correctly be handed down to specifying for designated equipment
domain.IPv4 address blocks issue specific code automatically：
IPv6 address blocks issue specific code automatically：
The YANG model interface design codes that address bulk state timing reports are as follows, equally including address block, address
The statistical information such as the incidence relation in pond and the maximum utilization rate and average service rate of address block.
Shown under the YANG model interface design codes that address resource reclaims automatically, the message only needs to tell equipment its need
The relevant information for the address block to be reclaimed, including id, Name and the relevant information such as address pool of its association, under explorer
Also need to carry device id parameter during hair to controller.
