example 1
[0159] This example first provides the application environment of the method provided by the embodiment of the present disclosure, such as Figure 7 As shown, the communication system corresponding to the application environment includes: a client and a routing device. A DHCP server is set in the routing device. exist Figure 7 The IP address assigned to the client by the DHCP server on the routing device is: 192.168.0.100, and the IP address of the routing device itself is: 192.168.0.1; of course, this is just an example, and the specific implementation is not limited to this example.
[0160] In order to ensure that the DHCP server inside the routing device works normally and can assign IP addresses to downstream access clients, it is necessary to ensure that the DHCP process itself and the parameters required for process startup are normal, so the following work needs to be done: Protect the data in the read-only partition from being Tampering to ensure that the process c...
example 2
[0170]The client is connected to the routing device through a network cable, wireless fidelity (Wireless Fidelity, WiFi), serial universal bus (Universal Serial Bus, USB) cable, etc. to realize the Internet access function. IP address. The IP address of the client can be manually configured by the user or automatically applied to the routing device through DHCP. Manual configuration of the IP address needs to be done manually by the user, so the user experience is not good and it is too professional. Automatically apply for an IP address from the routing device through DHCP.
[0171] Such as Figure 8 As shown, the parameter checking module: this module is responsible for checking the validity of the parameters required when the DHCP server process is started. The checked parameters include but are not limited to: the IP address of the gateway, the subnet mask of the gateway, the lease period, and the DHCP address pool The start IP address of the DHCP address pool and the en...
example 3
[0176] Such as Figure 9 As shown, this example provides a DHCP service provision method of a DHCP server, which may include:
[0177] Step 1: Before assigning an IP address, first check the validity of the parameters when the DHCP server process starts. First check whether the parameter is empty, if a parameter is empty, it is considered that there is a problem with the current parameter combination, go to step 6;
[0178] Step 2: After the non-empty check is completed, check the validity of the lease period. After the IP is assigned by DHCP, the client will renew the lease regularly. The timing of the lease renewal depends on the length of the lease. Therefore, the lease is a concept of time, and its value is a positive integer. On the premise that a positive integer is required, the lease period should not be too short. If it is too short, the client will frequently renew the lease, and a large number of DHCP messages will appear for the system. Moreover, the lease period...
