In this application, set up between UNP client and UNP service end after UNP is connected, can also service in UNP
The corresponding relation of UNP client and subaddressing pond is set on end, for example, as shown in table 1 below, UNP client is illustrated with son ground
The corresponding relation in location pond：
Table 1
| UNP client host is identified | Subaddressing pond |
| UNP client 12 | 192.168.10.0/29～192.168.10.7/29 |
| UNP client 13 | 192.168.10.8/29～192.168.10.15/29 |
In table 1 above, the corresponding relation with UNP client host mark with subaddressing pond represents UNP client and son
The corresponding relation of address pool.
Set up between UNP client 12 and UNP service end 11 after UNP is connected, UNP client 12 can open DHCP
Relay services, and application IP addresses request message is sent to UNP service end 11, the destination address in the application IP addresses request message is
For the IP address of UNP service end 11, for example, 192.168.1.1.
After UNP service end 11 receives the application IP addresses request message, can according to the UNP client exemplified by table 1 with
The corresponding relation in subaddressing pond, the host identification according to UNP client 12 determines the corresponding subaddressing pond of UNP client 12, from
An IP address is selected in the corresponding subaddressing pond, and such as 192.168.10.1/29 distributes to UNP client 12.
Subsequently, UNP client 12 is connected access device 121, access device 122 can pass through UNP client 12 to
The request distribution IP address of UNP service end 11.It should be noted that having the free time in the corresponding subaddressing pond of UNP client 12
In the case of IP address, the free IP addresses in subaddressing pond corresponding to 11 prioritizing selection UNP client 12 of UNP service end divide
The access device connected by dispensing UNP client 12.
Seen from the above description, it is generally the case that UNP service end 11 is set for the access being connected in same UNP client
Back-up joins the IP address in same subaddressing pond, so as to, it is achieved that UNP service end is unified to the IP address of access device

Topic.
In order to describe the IP address distribution method of the application offer in detail, in the application, from UNP service end and UNP visitor
Two, family end angle is described respectively.
As follows, the angle first from UNP service end is described：
Fig. 2 is referred to, illustrates one embodiment flow chart of the application IP address distribution method, flow process shown in the Fig. 2
On the basis of flow process shown in above-mentioned Fig. 1, by shown in Fig. 1 UNP service end 11 execute the method as a example by, can include with
Lower step：
Step S201：The application IP addresses request of UNP client transmission is received, in application IP addresses request, carries UNP client
The MAC Address of the connected access device in end.
In this application, so that access device 121 asks access network as an example, access device 121 can be connected to which
UNP client 12 sends application IP addresses request, and carries the MAC Address of access device 121 in the application IP addresses request.
After UNP client 12 receives the application IP addresses request, directly the application IP addresses request can be sent to UNP and take
Business end 11, it is also possible to after being packaged processing to the application IP addresses request, retransmit to UNP service end 11, to this in the application
It is not restricted.
Subsequently, UNP service end 11 can receive the application IP addresses request of the transmission of UNP client 12.
Step S202：Determine the corresponding subaddressing pond of UNP client.
In this application, after UNP service end 11 receives the application IP addresses request of UNP client transmission, UNP service end
11 can be according to the host identification of the UNP client, and for example, " UNP client 12 " inquires about above-mentioned table 1, such that it is able to find
The corresponding subaddressing pond of the UNP client is " 192.168.10.0/29～192.168.10.7/29 "
Step S203：Free IP addresses are selected in corresponding subaddressing pond as destination address.
Seen from the above description, in subaddressing pond, the quantity of IP address is limited, and wherein, each IP address is being distributed to
Access device, and in the case of lease is not yet due, the IP address does not allow to be reallocated to other access devices.In this application, it is
Description is convenient, unassigned IP address in subaddressing pond can be referred to as free IP addresses.
In this step, UNP service end 11 can select one in corresponding subaddressing pond determined by step S202
Individual free IP addresses, for example, select 192.168.10.2/29, using the free IP addresses as destination address.Specifically how from
Select free IP addresses as destination address at least one free IP addresses, the application is not restricted.
Additionally, in this application, if UNP service end 11 does not find sky in the subaddressing pond corresponding to UNP client 12
Not busy IP address, then it is considered that current no assignable IP address in the corresponding subaddressing pond, now, UNP service end 11
Free IP addresses can be selected from other subaddressing ponds, for example, selects 192.168.10.9/29, by the idle IP ground
Location is used as destination address.
Step S204：Destination address is sent to UNP client, so that destination address is distributed to MAC Address by UNP client
Corresponding access device.
In this application, after UNP service end 11 determines destination address, the destination address can be sent to UNP client
12, so that the destination address can be distributed to access device 121 by UNP client 12.
Additionally, in this application, UNP service end 11 can also detect the mask of the transmission of UNP client 12 and update request,
Concrete UNP client 12 is how to send mask to UNP service end 11 to update request, may refer to retouching in following embodiments
State, here is not first described further.
It should be noted that when UNP service end 11 detects the mask renewal request of the transmission of UNP client 12, UNP client
Hold in 12 corresponding subaddressing ponds and there are no free IP addresses.As described above, working as in the corresponding subaddressing pond of UNP client 12
When there are no free IP addresses, UNP service end 11 can determine free IP addresses as target from other subaddressing ponds
Address, it is assumed that for 192.168.10.9/29.And now, the IP address of UNP client 12 is 192.168.10.1/29, this two
Address is not belonging to same address field, cannot pass through UNP client 12 so as to UNP service end 11, be led to access device 121
Letter.
In order to solve the above problems, UNP service end 11 detect UNP client 12 transmission mask update request after,
Determine the mask-length of IP address in dhcp address pool, for example, 28, the mask-length of IP address in the dhcp address pool is taken
Band is updated in response message in mask, the mask is updated response message and is sent to UNP client 12.
After UNP client 12 receives mask renewal response message, the mask-length of own IP address is updated to DHCP
The mask-length of IP address in address pool, for example, after renewal, the IP address of UNP client 12 is 192.168.10.1/28.So
Operation, the IP address of UNP client 12 belongs to same address field with the IP address of access device 121, and UNP service end 11 is then permissible
By UNP client 12, communicated with access device 121.
As seen from the above-described embodiment, by, after the application IP addresses request for receiving the transmission of UNP client, determining the UNP
The corresponding subaddressing pond of client；From the corresponding subaddressing pond, preferentially select free IP addresses to send to UNP client
End, so that the free IP addresses are distributed to its access device for being connected by UNP client.As UNP service end is connection
The IP address that access device in same UNP client distributes in same subaddressing pond, so as to, it is achieved that UNP service end
The IP address of access device is managed collectively, meanwhile, the access connected by different UNP clients can be effectively prevented from and set
The problem that standby IP address is overlapped or conflicted.
Secondly, it is described from the angle of UNP client：
Fig. 3 is referred to, illustrates another embodiment flow chart of the application IP address distribution method, flow process shown in the figure
On the basis of flow process shown in above-mentioned Fig. 1, by shown in Fig. 1 UNP client 12 execute the method as a example by, can include with
Lower step：
Step S301：The application IP addresses request of access device transmission is received, in application IP addresses request, carries access device
MAC Address.
In this application, so that access device 121 asks access network as an example, access device 121 can be connected to which
UNP client 12 sends application IP addresses request, and carries the MAC Address of access device 121 in the application IP addresses request.
UNP client 12 can receive the application IP addresses request of access device transmission.
Step S302：Application IP addresses request is sent to UNP service end, so that UNP service end is asked according to application IP addresses
Determine a destination address, and destination address is sent to UNP client.
After UNP client 12 receives the application IP addresses request, directly the application IP addresses request can be sent to UNP and take
Business end 11, it is also possible to after being packaged processing to the application IP addresses request, retransmit to UNP service end 11, to this in the application
It is not restricted.
After UNP service end 11 receives the application IP addresses request, a target can be determined according to the application IP addresses request
Address, concrete UNP service end 11 is how to determine a destination address according to the application IP addresses request, may refer to above-mentioned figure
Associated description in 2 illustrated embodiments, will not be described in detail herein.
After UNP service end 11 determines destination address, the destination address can be sent to UNP client 12.
Step S303：Receive the destination address that UNP service end sends.
Step S304：Destination address is distributed to the corresponding access device of MAC Address.
UNP client 12 can receive the destination address of the transmission of UNP service end 11, and afterwards, UNP client 12 can be by
The destination address distributes to access device 121.
Additionally, UNP client 12 can also set up the target after the destination address for receiving the transmission of UNP service end 11
Corresponding relation between address and the MAC Address of access device 121.Subsequently, between UNP server 11 and access device 121 then
Can be communicated according to the corresponding relation.
Additionally, in this application, seen from the above description, IP address in each the subaddressing pond on UNP server 11
Quantity is limited, and in concrete subaddressing pond, the quantity of IP address can be calculated by the network segment and mask-length.
UNP client can count the number of times for sending application IP addresses request, and for example, UNP client is often sent out to UNP service end
Send primary address application to ask, default statistic is added 1, the initial value of the statistic is 0.When UNP client is to UNP
When the number of times of server transmission application IP addresses request reaches predetermined threshold value, the predetermined threshold value can be corresponding to the UNP client
Subaddressing pond in IP address quantity, it is believed that the no free IP addresses in the subaddressing pond corresponding to UNP client.
From the description in above-mentioned embodiment illustrated in fig. 2, when no free time IP ground in the corresponding subaddressing pond of UNP client
During location, UNP service end can select the free IP addresses in other subaddressing ponds.But now, in order to ensure to be subsequently the UNP visitor
After the free IP addresses that the access device connected by family end distributes in other subaddressing ponds, UNP server still can be with the UNP visitor
The access device connected by family end carries out proper communication, and UNP client can update the mask-length of own IP address so that
The IP address of UNP client belongs to same address field with the IP address of access device.
Specifically, when above-mentioned statistic reaches predetermined threshold value, UNP client can send mask to UNP service end
Request is updated, and the mask updates request and the mask-length of own IP address updated for representing UNP client request.
UNP service end 11 determines IP in dhcp address pool after the mask for detecting the transmission of UNP client 12 updates request
The mask-length of address, for example, 28, the mask-length of IP address in the dhcp address pool is carried and is disappeared in mask renewal response
In breath, and mask renewal response message is sent to UNP client 12.
After UNP client 12 receives mask renewal response message, the mask-length of own IP address is updated to DHCP
The mask-length of IP address in address pool, for example, after renewal, the IP address of UNP client 12 is 192.168.10.1/28.So
Operation, the IP address of UNP client 12 belongs to same address field with the IP address of access device 121, and UNP service end 11 then passes through
UNP client 12, is communicated with access device 121.
Additionally, in this application, when above-mentioned statistic reaches predetermined threshold value, UNP client can also pass through on ground
Location is renewed a contract to carry in asking and asks, for representing, the labelling for updating itself mask-length, receives the address so as to UNP server
Renew a contract after request, the labelling of itself mask-length can be updated according to the address renewed treaty request detection to UNP client request.
