Can according to different DHCP data packet forms, by the priority level of DHCP data packet be set as level-one, second level,
Three-level ... etc..Level-one indicates that priority level highest, second level, three-level ... successively indicate that priority level gradually decreases, when
So, in practical application, the mode of the priority level setting can also be other way, herein a different citing.
Step S202, if do not receive the Dynamic Host Configuration Protocol server return includes IP address within the default response time
Response message is then based on preset priority level, continues 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 comprising IP address returned, on the one hand may be the acquisition that the terminal device is sent with preset 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 is capable of handling the solicited message of the acquisition IP address of preset priority level, but the IP address that obtains
Phenomena such as loss of data or DHCP clothes occur during sending from terminal device to the Dynamic Host Configuration Protocol server for solicited message
Business device, which currently breaks down, to return to the response message comprising IP address to terminal device in time.So if in default response
In time, the response message comprising IP address that the Dynamic Host Configuration Protocol server returns is not received, is reducing the priority level
Before, it is also necessary to be based on preset 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 to Dynamic Host Configuration Protocol server based on preset priority level be greater than it is pre-
If when number, not receiving the response message comprising IP address that the Dynamic Host Configuration Protocol server returns yet, then reducing the priority
Grade.
In the embodiment of the present application, the request letter that terminal device is sent based on preset priority level to Dynamic Host Configuration Protocol server
Breath, solicited message of every transmissions wait for presetting the response time accordingly, if with preset priority level to DHCP service
When the number for the solicited message that device is sent is greater than preset times, do not receive the Dynamic Host Configuration Protocol server return yet includes IP address
Response message, described solicited message the problem of losing during transmission for obtaining IP address can be excluded substantially, it is described
Dynamic Host Configuration Protocol server possibly can not handle the solicited message of the acquisition IP address of preset priority level, at this moment just need to reduce institute
State priority level.
By way of example it is assumed that the preset priority level of DHCP data packet is second 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 packet of second level and obtains IP
The solicited message of address, if not receiving the response message comprising IP address that the Dynamic Host Configuration Protocol server returns in 3 seconds, then after
Continuous using priority level is that the DHCP data packet of second level sends to the Dynamic Host Configuration Protocol server and obtains the solicited message of IP address, often with
Priority level is that the DHCP data packet of second level sends the solicited message for obtaining IP address to the Dynamic Host Configuration Protocol server, is required
It is hair 5 times continuous in this way to 3 seconds response times, the sound comprising IP address that the Dynamic Host Configuration Protocol server returns still is not received
Information is answered, then reducing the priority level is three-level.
It should be noted that once being sent with obtaining IP with preset priority level to the Dynamic Host Configuration Protocol server any
In the default response time after the solicited message of location, if receiving the response letter comprising IP address that the Dynamic Host Configuration Protocol server returns
Breath, then without being further continued for sending the solicited message for obtaining IP address to 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 reducing is pre-
If in the response time, the response message comprising IP address that the Dynamic Host Configuration Protocol server returns still can not be received, then it represents that described
Dynamic Host Configuration Protocol server may still can not handle the solicited message of the priority level after reducing, at this moment, it is necessary to continue to reduce excellent
First grade grade.
Continue with the description citing in step S203, after priority level is reduced to three-level from second level, with three-level
Priority level sends the solicited message for obtaining IP address to Dynamic Host Configuration Protocol server, if still could not within 3 seconds response times
The response message comprising 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 the response comprising IP address that the Dynamic Host Configuration Protocol server returns still can not be received within 3 seconds response times
Information then continues to reduce priority level, priority level is reduced to Pyatyi from level Four ... ....
Priority level of every reduction requires to send with obtaining IP with newest priority level to Dynamic Host Configuration Protocol server
The solicited message of location, while the preset response time is needed to wait for, only within the preset response time, do not receive described
The response message comprising IP address that Dynamic Host Configuration Protocol server returns just will continue to reduce priority level.
The condition of termination is: after sending the solicited message for obtaining IP address to Dynamic Host Configuration Protocol server with arbitrary priority level
Response time in, receive the response message comprising IP address that the Dynamic Host Configuration Protocol server returns, be then not necessarily to continue to reduce excellent
First grade grade；Alternatively, being taken with minimum priority level to DHCP after priority level to be reduced to minimum priority level
In response time after the solicited message of device transmission acquisition IP address of being engaged in, the packet 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 sending with preset priority level continuous several times to Dynamic Host Configuration Protocol server
Solicited message, avoid and obtain IP address since DHCP data packet packet loss or the Dynamic Host Configuration Protocol server can not temporarily be handled
The problem of obtaining IP address caused by solicited message not successfully makes also by reducing the priority level of DHCP data packet step by step
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 packet of high priority grade, also can be by reducing the preferential of DHCP data packet step by step
Grade grade, so that improving the success rate that terminal device obtains IP address.
