Description

Address allocation method, system, device and computer-readable storage medium

Technical field

The present invention relates to the field of Internet technology, and in particular, to an address allocation method, system, equipment and computer-readable storage medium.

Background technique

At present, our devices with multiple network cards are very common, such as computers. Generally, the default configuration will support one wireless network card and one wired network card; or it can support plugging in an additional wired/wireless network card to change from a single network card to multiple network cards. For devices with multiple network cards, each network card may be assigned or reserved an IP address. Therefore, the device itself will perform IP address conflict detection on multiple network cards to avoid abnormal Internet access due to address conflicts. Under the existing DHCP (Dynamic HostConfiguration Protocol, Dynamic Host Configuration Protocol) address allocation strategy, it may cause address acquisition failure, and thus the Internet cannot be accessed. For example, when network card 1 is disconnected/the network card is disabled, and network card 2 requests the DHCP server to allocate an address, since network card 1 is disconnected/the network card is disabled, it will not respond to the DHCP server's ARP detection request, so DHCP The server will think that the address of network card 1 is not occupied and assign it to network card 2, causing an address conflict and causing multiple network card devices to fail to obtain addresses.

The current DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) address allocation strategy is generally allocated in order of the DHCP address pool range. ARP (Address Resolution Protocol) detection is performed before allocation. If ARP detects that the address has an ARP response, Then the next unallocated address will be allocated. For example, if the DHCP address pool range is 192.168.1.20 to 192.168.1.200, addresses will be allocated starting from 192.168.1.20. If there is an ARP response from ARP detection 192.168.1.20, it means that 192.168.1.20 has been occupied, and then ARP detection 192.168.1.21 will be sent. Until an available address is found and allocated to the corresponding network card and marked as allocated, or the addresses in the address pool are all occupied, the address allocation fails. For devices with multiple network cards, this method will repeatedly request available addresses if the assigned address is considered unavailable and not accepted, but the device has no way to feedback this situation to the DHCP Server (DHCP server, such as gateway), causing the DHCP Server to think that the address is available and keep allocating it, while the device thinks that the address between the network cards is unreasonable and refuses to accept it, causing the device to fail to obtain the address.

For example, in a computer with WINDOWS system, the address of network card 1 is 192.168.1.20, and when the network card is disconnected or the network card is disabled, network card 2 obtains the address. The DHCP Server considers 192.168.1.20 to be an available address and there is no response from ARP detection 192.168.1.20. This address can be allocated. 192.168.1.20 will be assigned to network card 2. The WINDOWS system will consider that this address conflicts with network card 1 and will not accept 192.168.1.20. It will continue to request available addresses. If 192.168.1.20 continues to be allocated to the computer, network card 2 will continue to be assigned. The computer cannot access the Internet because the address is not accepted.

Referring to Figure 1, a first embodiment of the present invention provides an address allocation method. The address allocation method includes the following steps:

Step S100, obtain the address allocation request of the network card to be allocated;

Specifically, the network card to be allocated may be a built-in or detachable network card in a multi-network card device. The network card to be allocated needs to obtain a corresponding IP address (Internet Protocol Address) before it can connect to the network, so that the corresponding multi-network card device can realize the Internet access function. Obtain the address allocation request sent by the network card to be allocated through the corresponding multi-network card device.

Step S200: Obtain an address to be allocated according to the address allocation request and preset allocation rules, and allocate the address to be allocated to the network card to be allocated;

Specifically, the preset allocation rule may be the above-mentioned DHCP address allocation policy, or may be other methods of obtaining addresses to be allocated for allocation. According to the address allocation request and the preset allocation rules, an address to be allocated is obtained, and the address to be allocated is allocated to the network card to be allocated, wherein the allocable address is within the range of the preset address pool and has not been allocated yet. occupied address.

Furthermore, the preset allocation rules include preset generation rules and second preset adjustment rules, and step S200 includes the following steps:

Step S210: Obtain the preselected address according to the address allocation request and the preset generation rules;

Step S220, determine whether the preselected address is occupied;

Step S221, if the preselected address is not occupied, use the preselected address as the address to be allocated;

Step S222: If the preselected address is occupied, generate a new preselected address according to the second preset adjustment rule, and execute step S220.

Specifically, the preset allocation rules include a preset generation rule and a second preset adjustment rule, and the preset generation rule is a rule for generating addresses within a preset address pool range. The second preset adjustment rule is used to adjust the preselected address to obtain an unoccupied preselected address as an address to be allocated. According to the address allocation request and the preset generation rules, a preselected address within the preset address pool range is obtained. Then, an ARP (Address Resolution Protocol, Address Resolution Protocol) detection operation is performed on the preselected address, and whether there is an ARP response from the preselected address is used to determine whether the preselected address is occupied. If there is no ARP response for the preselected address, it means that the preselected address is not occupied. If the preselected address is not occupied, the preselected address is used as the address to be assigned, and the address to be assigned is assigned to the network card to be assigned; if there is an ARP response to the preselected address, it means that the preselected address is occupied. If the preselected address is occupied, a new preselected address is generated according to the second preset adjustment rule, and step S220 is executed. If the new preselected address generated after adjustment by the second preset adjustment rule is not occupied, then The preselected address is used as an address to be allocated, and the address to be allocated is allocated to the network card to be allocated.

Furthermore, step S210 includes the following steps:

Step a1: After receiving the address allocation request, obtain the range information of the preset address pool;

Step a2: Select the starting address of the preset address pool as the preselected address according to the range information.

Specifically, after receiving an address allocation request sent by the network card to be allocated through the corresponding multi-network card device, the range information of the preset address pool is obtained, and the preset address pool is a set of addresses available for allocation. The range information of the preset address pool includes a range of addresses that can be used for allocation. According to the range information, the starting address of the preset address pool is selected as the preselected address. For example, if the preset address pool ranges from 192.168.1.20 to 192.168.1.200, then the addresses available for allocation are 192.168.1.20, 192.168.1.21, 192.168.1.22... until 192.168.1.200. Then the starting address of the preset address pool is 192.168.1.20, and 192.168.1.20 is used as the preselected address.

Furthermore, the second preset adjustment rule includes a second preset adjustment parameter, and step S222 includes the following steps:

Step b: Adjust the preselected address according to the second preset adjustment parameter to generate a new preselected address.

Specifically, the second preset adjustment rule includes a second preset adjustment parameter, and the second preset adjustment parameter is used to adjust the preselected address to generate a new preselected address. The second preset adjustment parameter may be a value selected according to specific needs, such as 1, 2, 3, etc. For example, the second preset adjustment parameter is 1, and when the preselected address 192.168.1.20 is occupied, a new preselected address 192.168.1.21 is generated. Then perform the step of: judging whether the preselected address is occupied, so that the new preselected address finally obtained is not occupied, then the preselected address is used as the address to be allocated, and the address to be allocated is allocated to the address to be allocated. network card.

Step S300, determine whether the address to be assigned is accepted by the network card to be assigned;

Specifically, after the address to be allocated is allocated to the network card to be allocated, the corresponding relationship between the address to be allocated and the identification information (such as MAC address, Media Access Control Address, physical address) of the network card to be allocated can be recorded, Then, if the same address is allocated to the same network card to be allocated more than the preset number of times within a certain period of time, or the network card to be allocated is still sending address allocation requests after allocation, it means that the address to be allocated is not the address to be allocated. Assigned network card accepted.

Furthermore, in another embodiment, step S300 also includes the following steps:

Step S310: Count the number of times the network card address allocation request to be allocated is sent within a preset time period;

Step S320, determine whether the number of sending times exceeds a preset number;

Step S321: If the preset number of times is exceeded, it is determined that the address to be allocated is not accepted by the network card to be allocated.

Specifically, the number of times the network card address allocation request to be allocated is sent within a preset time period (such as 20 seconds, 30 seconds, or 40 seconds, etc.) can be counted. Then it is determined whether the number of sending times exceeds a preset number (such as 3 times, 4 times or 5 times, etc.). If the number of sending times exceeds the preset number, it is determined that the address to be allocated is not accepted by the network card to be allocated. If the number of sending times does not exceed the preset number, it means that the address to be allocated is accepted by the network card to be allocated, the address is allocated successfully, and no other operations are required.

Step S400, if it is not accepted by the network card to be allocated, obtain a new address to be allocated according to the first preset adjustment rule, and perform the step of: determining whether the address to be allocated is accepted by the network card to be allocated.

Specifically, if the address to be allocated is not accepted by the network card to be allocated, a new address to be allocated is obtained according to the first preset adjustment rule, and the new address to be allocated is and the step is performed: judging the address to be allocated Whether it is accepted by the network card to be assigned. Wherein, the new allocable address is an address that is within the range of a preset address pool and is not occupied. The first preset adjustment rule is used to adjust the address to be allocated to obtain other unoccupied addresses to be allocated within the range of the preset address pool as new addresses to be allocated. If the address to be allocated is accepted by the network card to be allocated, it means that the address allocation is successful and no other operations need to be performed.

Furthermore, the first preset adjustment rule includes a first preset adjustment parameter, and step S400 includes the following steps:

Step S410: Adjust the address to be allocated according to the first preset adjustment parameter to generate a new address to be allocated.

Specifically, the first preset adjustment rule includes a first preset adjustment parameter, and the first preset adjustment parameter is used to adjust the address to be allocated to generate a new address to be allocated. The first preset adjustment parameter may be a value selected according to specific needs, such as 1, 2, 3, etc. The first preset adjustment parameter may be the same as the second preset adjustment parameter, or may be different. For example, the first preset adjustment parameter is 1, and when the address to be allocated 192.168.1.23 is not accepted by the network card to be allocated, a new address 192.168.1.24 is generated, and the new address is within the preset address pool range. When it is within the address and is not occupied, the new address is used as the new address to be allocated. Then perform the step of: determining whether the address to be assigned is accepted by the network card to be assigned.

In the first embodiment of the present invention, the address allocation request issued by the corresponding multi-network card device can be obtained by obtaining the network card to be allocated. Then, according to the address allocation request and the preset allocation rules, an address to be allocated is obtained, and the address to be allocated is allocated to the network card to be allocated, wherein the allocable address is within the range of the preset address pool and Unoccupied address. The preset allocation rule may be the above-mentioned DHCP address allocation policy, or may be other methods of obtaining addresses to be allocated for allocation. After the address to be allocated is allocated to the network card to be allocated, it is determined whether the address to be allocated is accepted by the network card to be allocated. If the address to be allocated is not accepted by the network card to be allocated, a new address to be allocated is obtained according to the first preset adjustment rule, and the new address to be allocated is and the step is executed: determine whether the address to be allocated is The network card to be assigned is accepted. Until the address to be allocated is accepted by the network card to be allocated, this avoids the situation where the DHCP Server always allocates the same address when multiple network card devices cannot accept the allocated address, resulting in failure to obtain the address and being unable to connect to the network, thus significantly reducing the cost. The failure rate of multi-network card devices in obtaining addresses.

Further, referring to Figure 2, a second embodiment of the present invention provides an address allocation method. Based on the embodiment shown in Figure 1, the address allocation request includes the MAC address of the network card to be allocated, and the preset generation rules include Default address algorithm, step S210 includes the following steps:

Step S211: Generate address parameters based on the MAC address of the network card to be allocated and the preset address algorithm;

Step S212: Generate a preselected address based on the address information of the preset address pool and the address parameters.

Specifically, the address allocation request may include the MAC address (Media AccessControl Address, physical address) of the network card to be allocated. When there is no requirement for the allocated address, the MAC address of the network card to be allocated and the preset address algorithm in the address allocation request may be used. Wherein, the preset address algorithm is used to calculate the MAC address to obtain corresponding address parameters, and the MAC address corresponds to the address parameters one-to-one. The preset address algorithm may be an SDBM hash algorithm, a DJB hash algorithm, a Lose lose hash algorithm, or other algorithms.

For example, if the SDBM hash algorithm is used for the MAC address, the corresponding code is:

for(j＝0,i＝0;i<hw_len;i++)

j+＝hwaddr[i]+(j<<6)+(j<<16)-j;

After calculation based on the MAC address through the preset address algorithm, the corresponding address parameter j is obtained. Assuming that the preset address pool range is 192.168.1.20 to 192.168.1.80, the corresponding preselected address is 192.168. 1.X, If the preselected address is not occupied, the unoccupied preselected address will be used as the address to be allocated. The range of the preset address pool can also be modulo, so as to prevent the calculated preselected address from exceeding the range of the preset address pool. Furthermore, for example, the code for the DJB hashing algorithm is:

for(j＝0,i＝0;i<hw_len;i++)

j＝j*33+(int)hwaddr[i];

For example, the code for the Lose lose hash algorithm is:

for(j＝0,i＝0;i<hw_len;i++)

j+=(int)hwaddr[i];

Those skilled in the art know that the specific preselected address algorithm can be selected according to actual needs.

In this embodiment, a preselected address is generated based on the MAC address of the network card to be allocated in the address allocation request and a preset address algorithm, and then based on the address information of the preset address pool and the address parameters. Wherein, the MAC address corresponds to the calculated address parameter one-to-one. Thereby, the MAC address of the network card to be allocated corresponds to the preselected address one-to-one, thereby reducing the possibility of duplication of the preselected address and ensuring the success rate of multiple network card devices in obtaining addresses.
