Local Area Networks, WLAN) or wired Ethernet (Ethernet) etc. communication mode.But system 10
When being deployed under different scenes, can be adjusted for also deployment scenario between the network equipment 11 and DHCP relay equipment 12
It is whole, for example, if system 10 is not the deployment of cross-region, then can choose between the network equipment 11 and DHCP relay equipment 12
Using WLAN or ethernet communication；And if system 10 is the deployment of cross-region, then the network equipment 11 and DHCP relay equipment
Ethernet communication can be then used between 12.In another example if the equipment amount disposed in system 10 is smaller, 11 He of the network equipment
Between DHCP relay equipment 12 can the communication in the consolidated network (private network), if but the equipment amount disposed in system 10 it is more huge
It greatly, then can be with cross-network segment communicating between the network equipment 11 and DHCP relay equipment 12.That is, in the network equipment 11 and DHCP
It can be selected based on actual conditions after the communication between equipment 12, and be not limited to the above-mentioned several ways enumerated.
In addition, the quantity of the network equipment 11, DHCP relay equipment 12 and terminal 13 all may be used in address pool management system 10
To be not limited to one.For example, each network equipment 11 at least one network equipment 11 can be at least one DHCP relay
Equipment 12 communicates, and each DHCP relay equipment 12 at least one DHCP relay equipment 12 then can be at least one end
13 communication of end.Certainly, as each equipment how quantity selection then can be according to the deployment of address pool management system 10 in practice
Scale determines.
For example, the address pool management system 10 of middle and small scale can use a network equipment 11, if the middle and small scale
It is deployed in address pool management system 10 in two floors, then the network equipment 11 then may be mounted at first layer or the second layer.Eventually
The DHCP relay equipment 12 connecting with the network equipment 11 can then be installed by holding in the first layer of 13 small numbers, and this
One DHCP relay equipment 12 can then be connect with 100 terminals 13 in first layer.In the more second layer of 13 quantity of terminal
Two DHCP relay equipment 12 connecting with the network equipment 11 can be then installed, first in two DHCP relay equipment 12
DHCP relay equipment 12 can be connect with 80 terminals 13 in the second layer, and second DHCP in two DHCP relay equipment 12
Trunking 12 can then be connect with 60 terminals 13 other in the second layer.If but the address pool management system of the middle and small scale
10, then it is contemplated that using two network equipments 11 scheme, 11 excess load of the network equipment is excessively caused to avoid equipment
The case where.
It is understood that any one terminal 13 that each network equipment 11 in address pool management system 10 is administered for it
The method flow for distributing address can be identical, therefore this programme for ease of understanding, the present embodiment will be based on a network equipment 11
One DHCP relay equipment 12 is illustrated this programme to distribute for address for terminal 13, but is not intended as to this programme
It limits.
Referring to Fig. 2, some embodiments of the present application provide a kind of address pool creation method, the address pool creation method
It can be executed by the network equipment, which may include: step S100, step S200 and step S300.
Step S100: the address assignment request message that DHCP relay equipment is sent is received, wherein the address assignment request
Message is that the terminal connecting with the DHCP relay equipment needs to be sent to the DHCP relay equipment when IP address requesting
Message.
Step S200: the address of DHCP relay equipment described in the address assignment request message is obtained, and is judged whether
In the presence of address pool corresponding with the address of the DHCP relay equipment.
Step S300: if it is not, creating the address pool.
The process of each step will be described in detail below.
In at least one terminal that DHCP relay equipment is connected, in some cases for example: address pool management system is rigid
At least one terminal that just deployment, DHCP relay equipment and DHCP relay equipment have been connected newly disposes and is added to address pool pipe
In reason system or have and increase new terminal and connect the DHCP relay equipment, then needing the network equipment by DHCP relay equipment is extremely
At least partly terminal distribution IP address of terminal for needing to distribute address in a few terminal.
The terminal of unallocated address with can detecting oneself also unassigned terminal IP by the address detected of self
Location, therefore the address assignment request message for requesting terminal IP address can be generated in the terminal of unallocated address, and into DHCP
After broadcasting the address assignment request message in the subnet that equipment is administered.In this way, the DHCP relay equipment can obtain the ground
Location distribution request message.DHCP relay equipment is based on the address assignment request packet parsing, can determine the address assignment request
Message is that the terminal of unallocated address needs to distribute corresponding IP address of terminal to network device requests.It and is that just the network equipment is true
Fixed which address pool to distribute address based on, the address of DHCP relay equipment oneself can be filled up to by DHCP relay equipment
Address assignment request message, for example, the address of DHCP relay equipment oneself to be filled up to the address word of address assignment request message
Duan Zhong is distributed so that the network equipment can be determined based on the address of DHCP relay equipment oneself based on which address pool
Address.In this way DHCP relay equipment can will carry DHCP relay equipment address address assignment request message by with net
Network equipment communication port is sent out.
It will be appreciated that if DHCP relay equipment obtains multiple address assignment requests of the corresponding broadcast of multiple terminals
Message, then the address of oneself then can be all filled up to more by DHCP relay equipment according to the sequence of acquisition address assignment request message
In a address assignment request message, and oneself IP can also be will fill according to the sequence for obtaining address assignment request message
Multiple address assignment request messages of address successively issue.Certainly, in some cases, if in certain address assignment request messages
The preferential processed mark of needs is carried, then compared with the processing in order of other address assignment request messages, DHCP relay
Equipment then can preferentially handle these and carry the address assignment request message for needing preferential processed mark.
It should be noted that DHCP protocol generally may include DHCPv4 agreement and DHCPv6 agreement, i.e. DHCPv4 agreement
It can be the distribution for carrying out the address IPv4, and DHCPv6 agreement can be the distribution for carrying out the address IPv6.Namely
It says, selection according to the actual situation, terminal can request the network equipment to distribute the address IPv4 for it, or can also request network
Equipment distributes the address IPv6 for it.Correspondingly, in the case where distributing the address IPv4, the address assignment request message of terminal generation
It can be the Discover message or Request message for supporting DHCPv4 agreement；But in the case where distributing the address IPv4, terminal
The address assignment request message of generation can be the Solicit message for supporting DHCPv6 agreement.
Step S100: the address assignment request message that DHCP relay equipment is sent is received, wherein the address assignment request
Message is that the terminal connecting with the DHCP relay equipment needs to be sent to the DHCP relay equipment when IP address requesting
Message.
In one case, DHCP relay equipment sends out address assignment request message from the port of network device communications
Afterwards, if difference is directly connected to by other equipment between the network equipment and DHCP relay equipment, then on the network equipment and being somebody's turn to do
The port that DHCP relay equipment sends out the port communication of address assignment request message can directly receive address distribution
Request message.
In another case, DHCP relay equipment sends out address assignment request message from the port of network device communications
Afterwards, if can be indirectly connected with by other equipment between the network equipment and DHCP relay equipment, then on the network equipment and being somebody's turn to do
The port that DHCP relay equipment sends out the port communication of address assignment request message can be based on other equipment to the address
The forwarding of distribution request message and receive the address assignment request message.Wherein, other equipment can be interchanger, gateway or
Bridge etc. has the network equipment of message transfer capability.
Step S200: the address of DHCP relay equipment described in the address assignment request message is obtained, and is judged whether
In the presence of address pool corresponding with the address of the DHCP relay equipment.
In the present embodiment, to avoid the occurrence of the case where address assignment request message is the message forged, e.g. forge
Relay request, then address assignment request message can then be made to carry some verification informations.Optionally, if address assignment request
Message is the message for meeting DHCPv4 agreement, then DHCPv4 agreement can be based on, terminal is generated address assignment request message
Rule be extended on the basis of agreement so that terminal generate address assignment request message editable field in carry
Verification information.And if address assignment request message is the message for meeting DHCPv6 agreement, since DHCPv6 agreement inherently can be with
Authentication option, such as Option10 are supported, then the information that can will be carried in the authentication option of address assignment request message
As verification information.
Correspondingly, the network equipment is that can accurately determine that address distribution is asked after obtaining address assignment request message
Ask whether message is message for distribution terminal IP address, then the verifying carried in the address assignment request message can be believed
Breath is verified.
As a kind of optionally mode verified, in general, verification information is difficult to be forged, therefore network is set
It is standby to be decapsulated to address assignment request message is obtained, to judge whether carry verifying in address assignment request message
Information judges whether the editable field of address assignment request message is empty, Huo Zhe in the case where DHCPv4 agreement
Whether the authentication option that address assignment request message is judged in the case where DHCPv6 agreement is empty.If editable field is empty or recognizes
Demonstrate,proving option is sky, then the network equipment, which can be determined that, does not carry verification information in the address assignment request message, and determining should
Address assignment request message is not intended to the message of request distribution terminal IP address, therefore can be based on other processing logical addresses point
Relevant treatment is carried out with request message, such as forwards the address assignment request message.If editable field is not empty or certification choosing
Xiang Buwei is empty, then the network equipment, which can be determined that, carries verification information in the address assignment request message, and determines the address
Distribution request message is the message for requesting distribution terminal IP address, therefore can pass through the subsequent processing of distribution terminal IP address
Process continues to handle the address assignment request message.
As another optionally mode verified, to improve safety, to avoid the case where forging verification information
Occur and can not be identified, then can preset verification information in the network equipment.In this way, in obtaining address assignment request message
After verification information, the network equipment can judge that the verification information in address assignment request message is based on default verification information
It is no identical as default verification information.If it is determined that it is to use that the network equipment, which can determine the address assignment request message not, to be not identical
In the message of request distribution terminal IP address, therefore can also be carried out at correlation based on other processing logical address distribution request messages
Reason.But if it is determined that be identical, then the network equipment can then determine that the address assignment request message is for requesting distribution terminal
The message of IP address, therefore can also be continued by the follow-up processing flow of distribution terminal IP address to the address assignment request message
It is handled.
In the present embodiment, determine that the address assignment request message is for requesting distribution terminal IP address in the network equipment
After message, the network equipment can go determination to be creation address pool or select which address pool based on address assignment request message
To distribute address.
Optionally, the network equipment obtains address assignment request message also based on the decapsulation to address assignment request message
Address field in DHCP relay equipment address.And since the creation of address pool in the network equipment can be dependent in DHCP
After the address of equipment, therefore the network equipment can be by the address of the DHCP relay equipment of acquisition and all address pools created
Match, to judge in all address pools created with the presence or absence of address pool corresponding with the address of DHCP relay equipment.
By taking IPv4 as an example, such as the address of DHCP relay equipment is 192.168.1.1, then correspondingly with the IP address
Location pond then can be 192.168.1.0/24.And it can not if address pool is 192.168.2.0/24 or 192.168.3.0/24
It is corresponding with the IP address.
Step S300: if it is not, creating the address pool.
The network equipment passes through matching, however, it is determined that there is the address pair with DHCP relay equipment in all address pools created
The address pool answered, then the network equipment is subsequent to distribute address based on the corresponding address pool.
And be to avoid the deployment of network from mistake occur to lead to address distribution also mistake, optionally, the network equipment can pass through
Port judges to determine whether there is the deployment mistake of network.In detail, the network equipment can be based on address pool and the creation ground
Incidence relation between the relied on address assignment request message in location pond is determined to receive the creation address pool by address pool
The receiving port of the address assignment request message relied on.In this way, the network equipment can judge to receive the creation address pool
The receiving port of the address assignment request message relied on and the receiving port of the current received address assignment request message are
No is same port.
If not same port, then it represents that the deployment of network has been likely to occur mistake, therefore the network equipment can be executed no longer
The process of subsequent address distribution, and generate the warning information of network error.The network equipment can show the warning information or
The warning information can also be sent to the terminal of corresponding administrator.For example, the address pool of creation is 192.168.2.0/
24, and the address of DHCP relay equipment is corresponding with address pool in currently received address assignment request message
192.168.2.2.This can indicate the currently received address assignment request message under normal circumstances, should from the wound
The identical port of receiving port for building the address assignment request message that the address pool is relied on receives.If but this is currently receivedly
Location distribution request message is really received from other ports, then illustrates the forwarding currently received address assignment request message
The deployment of DHCP relay equipment there is a problem.
Conversely, if same port, then it represents that the deployment of network is normal, therefore can continue the correspondence determined based on this
Address pool come continue distribute address.Wherein, the distribution about address will be in subsequent detailed description, then this is just no longer tired
It states.
The network equipment passes through matching, however, it is determined that there is no the addresses with DHCP relay equipment in all address pools created
Corresponding address pool, then the network equipment can determine that need to re-create one corresponding with the address of the DHCP relay equipment
Address pool carries out address distribution.
So during the network equipment creates address pool, if being based on DHCPv4 agreement, the network equipment can create one
A IP is corresponding with the IP address of the DHCP relay equipment and is the address pool of 24 bitmasks, for example, ground of 192.168.3.0/24
Location pond；If being based on DHCPv6 agreement, the network equipment can create the address Link of the address Link Yu the DHCP relay equipment
Address pool that is corresponding and being 96 bitmasks, for example, 2001: :/96 address pool.
Referring to Fig. 3, in some embodiments of the present application, after step S300, the address pool creation method of the application
Can also include: step S400, step S500 and step S600.
Step S400: it is based on the address assignment request message, configures the network equipment to the DHCP relay equipment
Routing.
Step S500: being the terminal distribution IP address of terminal based on the address pool.
Step S600: generating the response message for carrying the IP address of terminal based on the routing, and by the response report
Text is sent to the DHCP relay equipment.
The process of each step will be described in detail below.
Step S400: it is based on the address assignment request message, configures the network equipment to the DHCP relay equipment
Routing.
In the present embodiment, the network equipment, which creates address pool reason corresponding with the address of DHCP relay equipment, can be DHCP
Trunking first time and network device communications, therefore the network equipment can carry out routing based on address assignment request message and match
It sets, with Configuration network equipment to the routing between the DHCP relay equipment, so that routing subsequent voice of the network equipment based on the configuration
It can normally be communicated with the DHCP relay equipment.Be understood that, so-called configuration routing can be by the network equipment to this
DHCP relay equipment need by which node device the write-in of which port into route table items.
Step S500: being the terminal distribution IP address of terminal based on the address pool.
Furthermore the network equipment is based on after the address assignment request message creates corresponding address pool, and the network equipment can be with
Based on the address pool of creation come the terminal configurating terminal IP address to need request address.
Optionally, the network equipment can not had before based on random in the address pool of the creation or generation one by rule
The IP address of terminal generated.
But in the present embodiment, the network equipment has also preset some special preset IP address.It is so to avoid generating
IP address of terminal is identical as preset IP address and mistake occurs, therefore after generating IP address of terminal, the network equipment may determine that this
Whether IP address of terminal is identical as preset IP address.
If they are the same, then the network equipment can abandon the IP address of terminal of the generation, and can be based on the address pool of creation
An IP address of terminal is regenerated again, and judges whether the IP address of terminal regenerated is identical as preset IP address again.
Until the network equipment can determine the different terminal IP when generating IP address of terminal different with the preset IP address
Address is met the requirements.
If not identical, then the network equipment can directly determine meeting the requirements for the IP address of terminal.

After message, the network equipment can also obtain the new address of the new DHCP relay equipment carried in the new address assignment request message,
And judged in all address pools again with the presence or absence of corresponding address pool.
Corresponding address pool if it exists, then the network equipment, which also judges to receive, creates the address that the corresponding address pool is relied on
Whether the receiving port of the receiving port of distribution request message and the new address assignment request message is same port.If same
Interface, the network equipment are based on corresponding address pool then to distribute new terminal IP address, and take also based on corresponding routing to generate
New response message with new terminal IP address, and the new response message is also sent to new DHCP relay equipment.If not same
Interface, then new warning information also can be generated in the network equipment.
Corresponding address pool if it does not exist, then the network equipment also creates the new of the correspondence new address assignment request message
Address pool, and new terminal IP address is distributed based on the new address pool, and also will be based on the carrying of the new routing generation new terminal
The new response message of IP address is sent to new DHCP relay equipment.
