Server sends the solicited message for obtaining IP address, can accelerate the speed of DHCP processing.It can also be Best Effort shapes
Formula, this priority level can farthest obtain IP address.Priority level can be preset in terminal device, can basis
Priority level set in advance, the solicited message for obtaining IP address is sent to Dynamic Host Configuration Protocol server, and the priority level refers to
The priority level of the solicited message for obtaining IP address, or the priority level of DHCP data packets.
Step S102, if within the default response time, do not receive that the Dynamic Host Configuration Protocol server returns comprising IP address
Response message, then reduce the priority level.
In the embodiment of the present application, request of the Dynamic Host Configuration Protocol server in the acquisition IP address for receiving terminal device transmission
After information, if it is possible to handle, then can return to a response for including IP address to the terminal device that the solicited message is directed toward
Information, if Dynamic Host Configuration Protocol server can not handle the solicited message that this obtains IP address, can not return to the sound comprising IP address
Answer information, it is possible to set a response time, if within the default response time, the Dynamic Host Configuration Protocol server can be received
The response message for including IP address returned, represents successfully to obtain IP address, if within the default response time, does not receive institute
State Dynamic Host Configuration Protocol server return the response message for include IP address, then it represents that it is possible this acquisition IP address solicited message it is excellent
First level grade is too high, and Dynamic Host Configuration Protocol server can not handle this solicited message for obtaining IP address, in order to enable DHCP can be handled
The solicited message of the acquisition IP address received, can reduce the priority level for the solicited message for obtaining IP address.
Step S103, based on the priority level after reduction, the solicited message for obtaining IP address is sent to Dynamic Host Configuration Protocol server.
In the embodiment of the present application, after the priority level for the solicited message for obtaining IP address is reduced, it is possible to base
Priority level after reduction, the solicited message for obtaining IP address is sent to Dynamic Host Configuration Protocol server.If in this way, Dynamic Host Configuration Protocol server

Success rate.
Fig. 2 is the flow diagram of the method for the acquisition IP address that the another embodiment of the application provides, as shown in the figure the party
Method may comprise steps of：
Step S201, after the instruction for obtaining IP address is received, based on default priority level, to Dynamic Host Configuration Protocol server
Send the solicited message for obtaining IP address.
The step is consistent with step S101 contents, specifically can refer to the description of step S101, details are not described herein.
Can according to different DHCP data packet forms, by the priority level of DHCP data packets be arranged to level-one, two level,
Three-level ... etc..Level-one represents priority level highest, and two level, three-level ... represent that priority level gradually reduces successively, when
So, in practical application, the mode that the priority level is set can also be other manner, and differ a citing herein.
Step S202, if within the default response time, do not receive that the Dynamic Host Configuration Protocol server returns comprising IP address
Response message, then based on default priority level, continue to send the solicited message for obtaining IP address to Dynamic Host Configuration Protocol server.
In the embodiment of the present application, if terminal device does not receive the Dynamic Host Configuration Protocol server and return within the default response time
The response message for including IP address returned, is on the one hand probably the acquisition that the terminal device is sent with default priority level
The priority level of the solicited message of IP address is too high, and the Dynamic Host Configuration Protocol server can not be handled；On the other hand it is likely to be described
Dynamic Host Configuration Protocol server can handle the solicited message of the acquisition IP address of default priority level, but the IP address that obtains
Solicited message from terminal device to the Dynamic Host Configuration Protocol server send during occur loss of data phenomena such as or DHCP clothes
Business device currently breaks down can not return to the response message for including IP address to terminal device in time.So if in default response
In time, the response message for including IP address that the Dynamic Host Configuration Protocol server returns is not received, is reducing the priority level
Before, it is also necessary to based on default priority level, continue to send the solicited message for obtaining IP address to Dynamic Host Configuration Protocol server.
Step S203, if the number of the solicited message sent based on default priority level to Dynamic Host Configuration Protocol server is more than in advance
If during number, the response message for including IP address that the Dynamic Host Configuration Protocol server returns is not received yet, then reduces the priority
Grade.
In the embodiment of the present application, terminal device is believed based on default priority level to the request that Dynamic Host Configuration Protocol server is sent
Breath, often sends a solicited message, waits for the default response time accordingly, if with default priority level to DHCP service
When the number for the solicited message that device is sent is more than preset times, do not receive the Dynamic Host Configuration Protocol server return yet includes IP address
Response message, the solicited message of the acquisition IP address can be excluded substantially lost during transmission the problem of, it is described
Dynamic Host Configuration Protocol server possibly can not handle the solicited message of the acquisition IP address of default priority level, at this moment just need to reduce institute
State priority level.
By way of example it is assumed that the default priority level of DHCP data packets is two level in the terminal device, response is preset
Time is 3 seconds, and preset times are 5 times, and terminal device is sent to the Dynamic Host Configuration Protocol server with the DHCP data packets of two level and obtains IP
The solicited message of address, if in 3 seconds, does not receive the response message for including IP address that the Dynamic Host Configuration Protocol server returns, then after
The continuous DHCP data packets using priority level as two level send the solicited message for obtaining IP address to the Dynamic Host Configuration Protocol server, often with
Priority level sends the solicited message for obtaining IP address for the DHCP data packets of two level to the Dynamic Host Configuration Protocol server, is required for
To the response time of 3 seconds, so continuously hair 5 times, the sound for including IP address that the Dynamic Host Configuration Protocol server returns still is not received
Information is answered, then it is three-level to reduce the priority level.
It should be noted that once sent with obtaining IP to the Dynamic Host Configuration Protocol server with default priority level any
In the default response time after the solicited message of location, if receiving the letter of the response comprising IP address that the Dynamic Host Configuration Protocol server returns
Breath, then need not be further continued for sending the solicited message for obtaining IP address to the Dynamic Host Configuration Protocol server.
Step S204, based on the priority level after reduction, the solicited message for obtaining IP address is sent to Dynamic Host Configuration Protocol server.
The step is consistent with step S103 contents, specifically can refer to the description of step S103, details are not described herein.
Step S205, if within the default response time, do not receive the Dynamic Host Configuration Protocol server return yet includes IP address
Response message, then continue to reduce current priority level, and the solicited message for obtaining IP address is sent to Dynamic Host Configuration Protocol server,
The response message for including IP address returned until receiving the Dynamic Host Configuration Protocol server.
In the embodiment of the present application, if the solicited message of the acquisition IP address sent with the priority level after reduction is pre-
If in the response time, it still can not receive the response message for including IP address that the Dynamic Host Configuration Protocol server returns, then it represents that described
Dynamic Host Configuration Protocol server still may can not handle the solicited message of the priority level after reducing, at this moment, it is necessary to continue to reduce excellent
First level grade.
Continue with step S203 description illustrate, by priority level after two level is reduced to three-level, with three-level
Priority level sends the solicited message for obtaining IP address to Dynamic Host Configuration Protocol server, if within the response time of 3 seconds, still can not
The response message for including IP address that the Dynamic Host Configuration Protocol server returns is received, then continues to reduce priority level, by priority
Grade is reduced to level Four from three-level, then proceedes to send asking for acquisition IP address to Dynamic Host Configuration Protocol server with the priority level of level Four
Information is sought, if within the response time of 3 seconds, still can not receive the response for including IP address that the Dynamic Host Configuration Protocol server returns
Information, then continue to reduce priority level, priority level be reduced to Pyatyi from level Four ... ....
A priority level is often reduced, is required for sending with obtaining IP to Dynamic Host Configuration Protocol server with newest priority level
The solicited message of location, while the default response time is needed to wait for, only within the default response time, do not receive described
The response message for including IP address that Dynamic Host Configuration Protocol server returns, just may proceed to reduce priority level.
The condition of termination is：After the solicited message for obtaining IP address being sent with arbitrary priority level to Dynamic Host Configuration Protocol server
Response time in, receive the response message for including IP address that the Dynamic Host Configuration Protocol server returns, then need not continue to reduce excellent
First level grade；Alternatively, after priority level to be reduced to minimum priority level, taken with minimum priority level to DHCP
In response time after the solicited message of device transmission acquisition IP address of being engaged in, the bag that the Dynamic Host Configuration Protocol server returns still is not received
Response message containing IP address.
The embodiment of the present application obtains IP address by being sent with default priority level continuous several times to Dynamic Host Configuration Protocol server
Solicited message, avoid and obtain IP address since DHCP data packets packet loss or the Dynamic Host Configuration Protocol server can not be handled temporarily
The problem of obtaining IP address caused by solicited message not successfully, also by reducing the priority level of DHCP data packets step by step, makes
The solicited message for obtaining IP address can be sent with multiple priorities grade to Dynamic Host Configuration Protocol server by obtaining terminal device, in this way, even if
Dynamic Host Configuration Protocol server can not handle the DHCP data packets of high priority grade, also can be by reducing the preferential of DHCP data packets step by step
Level grade so that improve the success rate that terminal device obtains IP address.
