Detailed Description

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

The relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless specifically stated otherwise.

Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description.

Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.

In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

Fig. 1 is a schematic flow diagram of an address assignment method according to some embodiments of the present disclosure.

At step 102, an assignment request is received to assign an address to a user. Here, the address includes a first IP address, which is one of an IPv6 address and an IPv4 address.

In some embodiments, the allocation request may carry an identification of the user, such as a MAC address. Subsequent steps may be performed by parsing the allocation request to identify the identity of the user. In some embodiments, if the message parsing fails, an error log may be recorded.

At step 104, it is determined whether a second IP address has currently been assigned to the user. Here, the second IP address is the other one of the IPv6 address and the IPv4 address.

For example, it may be determined whether the user has been assigned the second IP address based on the MAC address of the user.

In step 106, if the user is currently assigned the second IP address, the user is assigned the first IP address.

In the above embodiment, by determining whether the second IP address is allocated to the user and then allocating the first IP address to the user, it is beneficial to associate the acquisition of the first IP address of the user with the acquisition of the second IP address, so that the user is ensured that the first IP address can be acquired only after the user acquires the second IP address, the problem that part of network resources can be accessed and the other part of network resources cannot be accessed is avoided, and the user experience can be effectively improved.

The inventor has noted that, due to the transition period from the IPv4 technology to the IPv6 technology, the situation that the IPv6 address can be allocated to the user but the IPv4 address cannot be allocated to the user occurs more frequently, and at this time, the user can access the network resource corresponding to the IPv6 address but cannot access the network resource corresponding to the IPv4 address.

According to some embodiments, the first IP address is an IPv6 address and the second IP address is an IPv4 address. In this case, an allocation request of an IPv6 address sent by the user is received, whether an IP v4 address has been allocated to the user is determined, and if an IPv4 address has been allocated to the user, an IPv6 address is allocated to the user. Therefore, the problem that the user can access the network resource corresponding to the IPv6 address but cannot access the network resource corresponding to the IPv4 address is effectively solved, the user experience is improved, and the user complaints are reduced.

FIG. 2 is a flow diagram of an address assignment method according to further embodiments of the present disclosure. In these embodiments, the first IP address is an IPv6 address and the second IP address is an IPv4 address. The specific implementation of steps 202-206 in the embodiment shown in fig. 2 can refer to the description of fig. 1, and only the steps different from fig. 1 will be described below.

In step 208, if the second IP address is not currently allocated to the user, a preset time is waited.

According to some embodiments, waiting for the preset time is based on a countdown of a timer or a countdown of a counter. It is understood that the preset time may be determined as needed.

In step 210, it is determined whether a second IP address is assigned to the user within a preset time.

In some implementations, a counter is set to a value of N (N >0), and the counter is decremented by one each time it is determined whether a second IP address is assigned to the user. In some implementations, if the value of the counter decreases to a negative number, the counter is considered to be malfunctioning, at which point an error log may be recorded. In some implementations, if the value of the counter/timer is decreased to zero, it is considered that the second IP address is not allocated to the user within the preset time, and the error log may also be recorded at the same time.

In step 212, if the second IP address is allocated to the user within the preset time, the first IP address is allocated to the user.

In the above embodiment, waiting for the preset time is beneficial to improving the success rate of the user for acquiring the first IP address, so that the success rate of the user for acquiring the second IP address is improved, and the user experience is favorably improved.

According to some embodiments, in step 208, it is determined whether there is an unallocated second IP address, and if there is an unallocated second IP address, a preset time is waited. Further, if there is no unallocated second IP address, the preset time is not waited.

In the embodiment, whether to wait for the preset time is determined based on whether the unallocated second IP address exists, so that the number of times of requesting allocation of the address by the user can be reduced, the waiting time of the user can be saved, and the user experience can be improved.

According to some embodiments, an error log may also be logged when assigning the first IP address to the user fails.

In the embodiment, the error log is recorded, so that the user can find out the fault reason when the network cannot be connected, and the user experience is further improved.

The address allocation method provided by the embodiment of the disclosure is suitable for a double-stack address allocation scene of a limited broadband network or a wireless broadband network.

FIG. 3 is a flow diagram of an address assignment method according to further embodiments of the present disclosure. Fig. 4 is a schematic illustration of address assignment success according to some embodiments of the present disclosure. Fig. 5 is a schematic illustration of address assignment failure according to some embodiments of the present disclosure. In these embodiments, the first IP address is an IPv6 address, and the second IP address is an IPv4 address.

At step 302, an assignment request is received to assign an address to a user. For example, the allocation request is sent by an IPv4/IPv6 dual stack terminal (e.g., notebook computer).

At step 304, the allocation request is parsed.

At step 306, a determination is made as to whether the resolution of the allocation request was successful. If yes, go to step 308; if not, go to step 322.

At step 308, it is determined whether the user is currently assigned an IPv4 address. If yes, go to step 310; if not, go to step 318.

At step 310, an IPv6 address is assigned to the user.

At step 312, a determination is made whether assigning an IPv6 address to the user was successful. If yes, go to step 314; if not, go to step 328.

At step 314, a Dynamic Host Configuration Protocol (DHCP) response is sent. For example, the DHCP response is sent to the IPv4/IPv6 dual stack terminal.

At step 316, a success log is recorded. As shown in fig. 4, the IPv4/IPv6 dual-stack terminal obtains an IPv4 address and an IPv6 address, respectively.

At step 318, the counter is set to a value of N.

In step 320, it is determined whether the value N of the counter is less than or equal to zero. If yes, go to step 322; if not, go to step 324.

At step 322, an error log is recorded. As shown in fig. 5, at this time, the IPv4/IPv6 dual-stack terminal cannot obtain the IPv4 address and the IPv6 address, for example, the notebook computer may display a network connection failure.

At step 324, a determination is made whether the user is currently assigned an IPv4 address. If yes, go to step 310; if not, go to step 326.

In step 326, the counter value N is decremented by one.

At step 328, an error log is recorded. It should be understood that at this time, the IPv4/IPv6 dual-stack terminal cannot obtain the IPv4 address and the IPv6 address, and for example, a notebook computer may display a network connection failure.

In the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same or similar parts in the embodiments are referred to each other. For the device embodiment, since it basically corresponds to the method embodiment, the description is relatively simple, and for the relevant points, reference may be made to the partial description of the method embodiment.
