It should be noted that address distribution method provided by the embodiment of the present invention can be adapted for arbitrary network, for example,
It can be adapted for common single machine access network (network of no backup server), be readily applicable to active/standby backup access net
Network, and active/standby backup access network can be based on and VRRP (Virtual Router Redundancy Protocol, virtual road
By redundancy protocol) downlink data of similar any protocol forward terminal, so-called active/standby backup network refers to each access service
All there is the backup link being associated in the current ink under device, and current ink is under the jurisdiction of different accesses from backup link and takes
Business device.If there is failure in current ink, the terminal being connected on current ink can be moved on backup link namely this
When terminal can pass through backup link and top service device interaction data, it should be noted that current ink is there may be multiple
The backup link being associated can be from this multiple backup link when moving to the terminal on current ink on backup link
In preferentially select the higher backup link of priority as carry these terminals link, at this point, current ink can be from main work
State is switched to idle state and becomes backup link, and backup link selected accordingly will be switched to by idle state
Main working condition and become current ink.
In access net, since user terminal is often to issue access request in the form of broadcast, so in the free time
The link of state (Status of Backups) may also can receive the access request of user, so in step S101, from presetly
Can also include: before inquiring address field corresponding with the link in the resource pool of location
Determine that the link under the access server is in main working condition.
After main working condition being in determining the link under the access server, then from preset geological resource pond
It is middle to inquire address field corresponding with the link, however, it is determined that the link is in main working condition, that is to say, bright and the link association
Backup link just should be at idle state at this time, if so other backup links also receive the access request of terminal at this time,
The access request received can be determined as in vain by the access server where other backup links, or can also directly by
The access request abandons.
It is handed down to it should be noted that extracting the target communication address being in idle condition from the address field inquired
Can also include: before terminal
It determines that the quantity of the address being in idle condition in the address field that inquires is more than or equal to be currently received
The quantity of access request.
In some embodiments, however, it is determined that the quantity for the address being in idle condition in the address field inquired is less than
When the quantity for the access request being currently received, new address field application request can be issued for the link, and obtain in the link
When to new address field, the target communication address being in idle condition is extracted from new address field and is handed down to terminal；In addition,
Can also start timing issuing new address field application request, if after preset time arrival the link still have not been obtained it is new
Address field can be sent out alarm notification, to prompt network management personnel.
Because can unify when access server currently receives the access request of multiple terminals by a certain link
Address field corresponding with the link is inquired from preset address resource pond, however, it is determined that in idle shape in the address field inquired
The quantity of the address of state is more than or equal to the quantity for the access request being currently received, then illustrates in address field to include enough

Location section, which is not able to satisfy, this time distributes, and can issue new address field application request at this time, certainly, issue new address field application when
Wait, if current queries to address field in there is also the address being in idle condition, these directly can be in sky
The address of not busy state is handed down to each terminal respectively, then can be from new address when the link gets new address field
Target communication address is extracted in section and is handed down to the terminal for receiving address not yet, and in other words, this issues access
A part of terminal corresponding address of request can be to be obtained from new address field, is also possible to from being in advance the chain
It is obtained in the address field that road is correspondingly arranged.
It should be noted that can include by the address field that a certain link is correspondingly arranged in advance in some embodiments
An amount threshold is arranged in address, for example, in the quantity for detecting the address being in idle condition in the address field
When less than the preset quantity threshold value, alarm prompt can be issued to network administrator, to remind network administrator note that needing to infuse
Meaning can just be the new address field of the link application, apply for that the movement promoter of new address field can be the chain at this moment
Access server where road, is also possible to network management personnel, this new address field can be the corresponding place of other links
In the address field of idle state, it is also possible to an address field in advance for the link reserves.It of courses, new Shen in the present embodiment
It should also be as containing at least two continuous address in address field please.
In the present embodiment, when a certain link at least corresponds to two available address sections, when being stored with this in the resource pool of address
The mapping relations of link and at least two available address sections, and when each available address section carries pre-set priority mark, from looking into
Extracting the target communication address being in idle condition in the address field ask and being handed down to terminal to include:
The higher address field of priority is selected from available address section with carrying out target communication according to pre-set priority mark
The extraction of location.
It is understood that above-mentioned available address section is from the address field being correspondingly arranged in advance for the link.Certainly,
In some cases, a certain link at least correspond to two available address fields when, these available address fields be also possible to for
The address field that the link is newly applied, at this point, being exactly to extract the target being in idle condition from the address field of these new applications
Address is handed down to each terminal.
It should be noted that no matter the corresponding available address section of a certain link derives from where, as long as can land used from this
The extraction of target communication address is carried out in the section of location, so that it may extract according to following principle:
When the address in this multiple available address section is all in idle state, can at random from this it is multiple can land used
One is selected in the section of location as the current destination address section for extracting target communication address, it is of course also possible to according to preset preferential
Grade sequential selection destination address section, it is notable that, should be first when the link receives the access request of terminal again
Judge whether there is also the addresses being in idle condition in current destination address section, if it is not, reselecting new target
Otherwise address field carries out the selection of address out of current destination address section again.
Network is accessed for active/standby backup, address distribution method provided by the present embodiment can also include: to detect
When a certain link first time access terminal in access server, the access server where the link can upward stratum server
The corresponding address field routing of the link is sent, includes the corresponding address field of the link, such top service device in address field routing
It can be determined according to the sender that address field routes when carrying out data interaction with the terminal under this address field, it should logical
The forwarding which access server carries out data is crossed, since the link is in first time access terminal, connecing where the link
Entering server is that upward stratum server is put on record as unit of address field, so for the link, at current time
There is terminal to access the link again later, and there is also the addresses being in idle condition in the corresponding address field of the link
When, since upward stratum server has sent the address field to access server before, so at this point, access server is also with regard to nothing
Putting on record for address need to be carried out by stratum server again up, because the address belongs to the address field put on record, namely
Access server where the link only needs to send an address field when the link is initially used, without at this
One address is sent with regard to upward stratum server when link one terminal of every access, compares and is convenient for managing concentratedly.Also need
It is noted that in some embodiments, can also just first pass through in advance access service before the link first time access terminal
The upward stratum server of device puts the routing of address field corresponding to the link on record.
Address distribution method provided by the present embodiment can also include:
When detecting that the main working condition of a certain chain routing in access server is switched to idle state, due to the link
It is in main working condition before, so the link inevitable stratum server upwards when being used first time has sent address field road
By so the access server where the link stratum server can send the link corresponding address field routing and remove upwards at this time
Pin notice, should with cancel that the upward stratum server when the link is used for the first time of the access server where the link sends
The corresponding address field of link routes, and includes the corresponding address field of the link in address field routing.
Or,
When detecting that the main working condition of a certain chain routing in access server is switched to idle state, where the link
Access server routing priority reduction flag added be sent to top service in the link corresponding address field routing
Device, address field routing in include the corresponding address field of the link, in this way, upper layer device can select which is used according to priority
One access server carries out the forwarding of data.It should be noted that it is single that access server, which is with address field, in the present embodiment
The upward stratum server in position is put on record, and that is to say reduces the unified addition of mark on address field for priority, that is to say uniformly
The adjustment of priority has been carried out to the address in the address field, has been carried out respectively compared to each scattered address
For adjustment, control, the adjustment of priority with raising efficiency, can be easily facilitated.
It should be noted that when a certain chain routes main working condition and is switched to idle state, then it is standby each other with the link
It is main working condition that another link of part link, which is possible to be switched by idle state,.
So address distribution method provided by the present embodiment can also include:
When detecting a certain chain routing idle state switching in access server is main working condition, where the link
Access server can send the link corresponding address field routing by stratum server upwards, include the link in address field routing
Corresponding address field, it should be appreciated that a certain chain routing idle state switching is main working condition, can be with the link first
Secondary access terminal is corresponding, it is of course also possible to it is corresponding to route main working condition switching idle state with another chain, at this time namely table
The terminal of another chain road in face is moved to this chain road and carries out data interaction with top service device.
It should be noted that can in the address field routing that the upward stratum server of access server where a certain link is sent
Only to include the corresponding address field of the link, certainly, in addition to may include the link in address field routing in some embodiments
Except corresponding address field, the information of the access server where the link can also be included.If for example, by A access service
The upward stratum server of device has sent the routing of address field, includes a address field in address field routing, due to top service device be from
A access server receives address field routing, so when top service device needs to carry out data with the terminal under a address field
Data will be forwarded by A access server when interaction, can also simultaneously include A access service in address field routing certainly
The identification information of device, top service device is according to the identification information it may determine that going out to need through which access server and be somebody's turn to do
Terminal under link carries out data interaction.
Address distribution method provided in an embodiment of the present invention, by detecting that access server received by a certain link
To terminal access request when, corresponding with link address field is inquired from preset address resource pond, in address resource pond
The mapping relations of the corresponding address field of each link are stored with, two are included at least in each address field continuously communicatively
Then location extracts the target communication address being in idle condition from the address field inquired and is handed down to terminal, due to same
The address of chain road terminal is all by inquiring address field corresponding with the link, and extraction obtains out of this address field,
So the address of the terminal distribution on same link just compares concentration, the pipe being thus more convenient in Unified Set
Reason moreover, when the link state in which changes, such as from main working condition is switched to idle state, or by the free time
When state switching is main working condition, the access server where the link can be unified to carry out the publication of address field routing,
In, it may include that unified upward stratum server puts address field on record, or unification carries out the adjustment of priority as unit of address field.
Embodiment two:
In order to better understand the present invention, the embodiment of the present invention provides a kind of more specifical on the basis of example 1
Address distribution method, it is shown in Figure 2, comprising:
S201: detect that access server currently receives the access request of terminal by a certain link.
S202: judging whether the link is in main working condition, if so, S203 is gone to, if not, going to S208.
S203: address field corresponding with the link is inquired from preset address resource pond.
It should be understood that being stored with reflecting for the corresponding address field of each link in address resource pond in the present embodiment
Relationship is penetrated, includes at least two continuous addresses in each address field.
For example, a big address field A is by A1, A2, A3 ..., these small address fields of An are formed, and are existed in current network
Two associated access servers are the first access server and the second access server, the first access server and respectively
It is synchronous that two access servers can carry out data by heartbeat, wherein include link A and link B under the first access server,
It include link A ' and link B ' under second access server, wherein link A and link A ' main/slave link each other, link B and link
B ' main/slave link each other.Assuming that the corresponding relationship of link A, link A ' and A1 address field are stored in the resource pool of address, link B,
The corresponding relationship of link B ' and A2 address field.
S204: judge whether the quantity for the address being in idle condition in the address field inquired is more than or equal to currently
The quantity of the access request received, if so, S205 is gone to, if not, going to S206.
S205: the target communication address being in idle condition is extracted from the address field inquired and is handed down to terminal.
Assuming that the link A and link B in the present embodiment have received the access request of terminal, then the first access server
Should respectively to terminal distribution address A1.1, A1.2, A1.3 etc. under A link, to B link under terminal distribution communication
Address A2.1, A2.2, A2.3 etc..If receiving terminal access request for the first time at the time of correspondence in step S201 for the link
Moment then should also be put on record address field routing as the upward stratum server of the access server where the link in step S205,
I.e. upward stratum server sends A1 address field and A2 address field, finishes if the address in A1 address field is assigned, link A
It is upper to have received new access request again, then it can apply for A3 address field, and stratum server sends the routing of A3 address field, tool upwards
Body may refer to shown in Fig. 3.
When variation has occurred in link A state in which (when being switched to idle state from main working condition), the first access
Server can send A1 address field route withdraw notice by stratum server upwards, so top service device can be by A1 address field road
By being cancelled, therefore it is main working condition that link A ' will be switched by idle state, and the second access server will be to upper layer
Server sends the routing of A1 address field, therefore, will be issued later by the second access server to the terminal under A1 address field
Data are forwarded.Due to link B and it is abnormal, continue by the first access server to the terminal under A2 address field
The data of sending are forwarded, and specifically may refer to shown in Fig. 4.
S206: new address field application request is issued, for the new address field of the link application.
S207: target communication address is extracted when the link gets new address field, in the address field new from this and is issued
To terminal.
S208: the access request is abandoned.
Address distribution method provided in an embodiment of the present invention, by detecting that access server received by a certain link
To terminal access request when, corresponding with link address field is inquired from preset address resource pond, in address resource pond
The mapping relations of the corresponding address field of each link are stored with, two are included at least in each address field continuously communicatively
Then location extracts the target communication address being in idle condition from the address field inquired and is handed down to terminal, due to same
The address of chain road terminal is all by inquiring address field corresponding with the link, and extraction obtains out of this address field,
So the address of the terminal distribution on same link just compares concentration, the pipe being thus more convenient in Unified Set
Reason, for example, being easier to carry out the concentration adjustment of routing.
Embodiment three:
Shown in Figure 5, the present embodiment provides a kind of address distributing devices, comprising:

Address issues module 52, for extracting the target communication address being in idle condition from the address field inquired
It is handed down to terminal.
The mapping relations of the corresponding address field of each link are stored in address resource pond in the present embodiment, eachly
Two continuous addresses are included at least in the section of location.
It should be understood that each link can correspond to an address field, multiple address fields can also be corresponded to, for one
For address field, wherein may include multiple continuous addresses, for example, can be 10,20 etc..It needs to illustrate
It is that the mapping relations of the corresponding address field of each link in the present embodiment in address resource pond can be by network management personnel
It pre-sets, and can be modified by network management personnel to it in subsequent communication process, network management personnel
When for its corresponding address field of each link setting, it can be set according to the number of users that each link can respectively carry
It sets, for example, if the number of users that can carry of a certain link is larger, the address for including in the corresponding address field of the link
The quantity of quantity address corresponding compared to other links can be larger, in order to enable the terminal pair under same link
The address answered more is concentrated, and only can be correspondingly arranged an address field in advance for each link, be can wrap in the address field
Containing multiple continuous addresses.
In addition, the mapping relations of the corresponding address field of each link stored in address resource pond can be and directly reflect
Relationship is penetrated, for example, direct associated storage directly can be carried out for the corresponding address field of each link and the link, but is being had
In a little situations, such as in active/standby backup access network, can there is a situation where that the corresponding address field of multiple links is identical, at this point,
It can also be correspondence other than it the corresponding address field of each link and the link directly can be carried out direct associated storage
This identical one mapping relations of multiple link establishments of address field, so at this time can be only by a chain in this multiple link
The corresponding address field in road carries out direct associated storage.It, can be with for example, link A address field corresponding with link A ' is identical
Understand, link A at this time and link A ' should main/slave link each other, can by link A and link A ' together with it is corresponding
Address field is associated storage, or the corresponding address field of link A can also be associated storage, while storing link
The mapping relations of A and link A '.
It should be understood that a certain link under access server, can receive the access request of multiple terminals simultaneously,
At this point, address field enquiry module 51, which should be each terminal, inquires address field corresponding with the link, and by under address
Hair module 52 extracts target communication address from the address field inquired and is handed down to these terminals for issuing access request respectively.
It should be noted that address distributing device provided by the embodiment of the present invention can be adapted for arbitrary network, for example,
It can be adapted for common single machine access network (network of no backup server), be readily applicable to active/standby backup access net
Network, and active/standby backup access network can be based on VRRP (Virtual Router Redundancy Protocol, virtual flow-line
Redundancy protocol) forwarding terminal downlink data, so-called active/standby backup network refers to the current ink under each access server all
In the presence of the backup link being associated, and current ink is under the jurisdiction of different access servers from backup link.If current ink
There is failure, then can move to the terminal being connected on current ink on backup link, namely terminal at this time can pass through
Backup link and top service device interaction data, it should be noted that current ink may exist multiple backups being associated
Link can preferentially select preferential when moving to the terminal on current ink on backup link from this multiple backup link
The higher backup link of grade is as the link for carrying these terminals, at this point, current ink can be switched to the free time from main working condition
State and become backup link, and backup link selected accordingly will be switched by idle state is main working condition and become
