The current DHCP (Dynamic Host Configuration Protocol) Address allocation policy is generally allocated in sequence according to a DHCP Address pool range, ARP (Address Resolution Protocol) detection is performed before allocation, and if ARP detects that the Address has an ARP response, the next unallocated Address is allocated. For example, if the DHCP address pool range is 192.168.1.20 to 192.168.1.200, the address allocation is started from 192.168.1.20, and if the ARP probe 192.168.1.20 responds with an ARP response, it indicates that 192.168.1.20 is occupied, and then the ARP probe 192.168.1.21, until an available address is found and allocated to a corresponding network card, and the address is identified as allocated, or the addresses in the address pool are all occupied, the address allocation fails. For a device with multiple network cards, if the allocated address is considered to be unavailable and not acceptable, the method can repeatedly request the available address, but the device has no way to feed back the situation to a DHCP Server (such as a DHCP Server, like a gateway), so that the DHCP Server considers that the address is available and is allocated all the time, and the device considers that the address between the network cards is unreasonable and is not acceptable all the time, thereby causing the device to fail in acquiring the address.
For example, in a computer of WINDOWS system, the address of the network card 1 is 192.168.1.20, and when the network is disconnected/disabled, the network card 2 acquires the address, the DHCP Server considers 192.168.1.20 as an available address and ARP probe 192.168.1.20 does not respond, the address can be allocated, 192.168.1.20 is distributed to the network card 2, the WINDOWS system considers that the address conflicts with the network card 1 and does not accept 192.168.1.20, and continues to request the available address, and if 192.168.1.20 is continuously allocated to the computer, the network card 2 cannot access the network because the address is not accepted all the time.
Referring to fig. 1, a first embodiment of the present invention provides an address allocation method, including the steps of:
step S100, acquiring an address allocation request of a network card to be allocated;
specifically, the network card to be distributed may be a built-in or detachable network card in a multi-network card device. The network card to be allocated may be connected to the network only after acquiring a corresponding IP Address (Internet Protocol Address), so that the corresponding multi-network-card device may implement the Internet access function. And acquiring an address allocation request sent by the network card to be allocated through the corresponding multi-network-card equipment.
Step S200, obtaining an address to be allocated according to the address allocation request and a preset allocation rule, and allocating the address to be allocated to the network card to be allocated;
specifically, the preset allocation rule may be the DHCP address allocation policy described above, or may be another method for acquiring an address to be allocated for allocation. And acquiring an address to be allocated according to the address allocation request and a preset allocation rule, and allocating the address to be allocated to the network card to be allocated, wherein the allocable address is an unoccupied address in a preset address pool range.
Further, the preset distribution rule includes a preset generation rule and a second preset adjustment rule, and the step S200 includes the following steps:
step S210, obtaining a preselected address according to the address allocation request and a preset generation rule;
step S220, judging whether the preselected address is occupied or not;
step S221, if the preselected address is not occupied, the preselected address is used as an address to be allocated;
step S222, if the preselected address is occupied, generating a new preselected address according to a second preset adjustment rule, and executing step S220.
Specifically, the preset allocation rule includes a preset generation rule and a second preset adjustment rule, and the preset generation rule is a rule for generating an address within a preset address pool range. The second preset adjusting rule is used for adjusting the preselected address to obtain an unoccupied preselected address serving as an address to be allocated. And obtaining a preselected address in a preset address pool range according to the address allocation request and a preset generation rule. And then, performing ARP (Address Resolution Protocol) detection operation on the preselected Address, and judging whether the preselected Address is occupied or not according to whether the preselected Address has an ARP response or not. And if the preselected address has no ARP response, indicating that the preselected address is not occupied. If the preselected address is not occupied, taking the preselected address as an address to be allocated, and allocating the address to be allocated to the network card to be allocated; and if the preselected address has an ARP response, indicating that the preselected address is occupied. If the preselected address is occupied, generating a new preselected address according to a second preset adjustment rule, executing step S220, and if the new preselected address generated after the adjustment of the second preset adjustment rule is not occupied, taking the preselected address as an address to be allocated, and allocating the address to be allocated to the network card to be allocated.
Further, step S210 includes the steps of:
step a1, after receiving the address allocation request, obtaining range information of a preset address pool;
step a2, selecting the initial address of the preset address pool as a preselected address according to the range information.
Specifically, when an address allocation request sent by a network card to be allocated through a corresponding multi-network-card device is received, range information of a preset address pool is obtained, where the preset address pool is a set of addresses available for allocation. The range information of the preset address pool comprises a range of addresses which can be used for allocation, and according to the range information, the initial address of the preset address pool is selected as a preselected address. For example, if the predetermined address pool ranges from 192.168.1.20 to 192.168.1.200, the addresses available for allocation are 192.168.1.20, 192.168.1.21, 192.168.1.22 … … and 192.168.1.200. The starting address of the preset address pool is 192.168.1.20, and 192.168.1.20 is used as the preselected address.
Further, the second preset adjustment rule includes a second preset adjustment parameter, and step S222 includes the following steps
And b, adjusting the preselected address according to a 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 for adjusting the preselected address to generate a new preselected address. The second preset adjustment parameter may be a value selected according to a specific requirement, such as 1, 2, 3, and the like. 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 the following steps are executed: and judging whether the preselected address is occupied or not so as to enable a finally obtained new preselected address to be unoccupied, taking the preselected address as an address to be allocated, and allocating the address to be allocated to the network card to be allocated.
Step S300, judging whether the address to be distributed is accepted by the network card to be distributed;
specifically, after the Address to be allocated is allocated to the network card to be allocated, a corresponding relationship between the Address to be allocated and identification information (such as a MAC Address, a Media Access Control Address, a physical Address) of the network card to be allocated may be recorded, and then, if the number of times that the same Address is allocated to the same network card to be allocated within a certain period of time exceeds a preset number of times or the network card to be allocated still sends an Address allocation request after allocation, it is determined that the Address to be allocated is not accepted by the network card to be allocated.
Still further, in another embodiment, the step S300 further includes the steps of:
step S310, counting the sending times of the network card address allocation request to be allocated in a preset time length;
step S320, judging whether the sending times exceed preset times;
step S321, if the number of times exceeds the preset number, it is determined that the address to be allocated is not accepted by the network card to be allocated.
Specifically, the sending times of the allocation request of the network card address to be allocated within a preset time period (for example, 20 seconds, 30 seconds, or 40 seconds, etc.) may be counted. And then judging whether the sending times exceed a preset number (such as 3 times, 4 times or 5 times). And if the sending times exceed the preset times, judging that the address to be distributed is not accepted by the network card to be distributed. If the sending times do not exceed the preset times, the fact that the address to be allocated is accepted by the network card to be allocated is indicated, address allocation is successful, and other operations do not need to be executed.
Step S400, if the network card to be distributed is not accepted, a new address to be distributed is obtained according to a first preset regulation rule, and the steps are executed: and judging whether the address to be distributed is accepted by the network card to be distributed.
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 a first preset adjustment rule, and the new address to be allocated is the address to be allocated which is obtained by executing the following steps: and judging whether the address to be distributed is accepted by the network card to be distributed. And the new distributable address is an unoccupied address in a preset address pool range. The first preset adjusting rule is used for adjusting the address to be allocated so as 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, the address allocation is successful, and other operations are not required to be executed.
Further, the first preset adjustment rule includes a first preset adjustment parameter, and the step S400 includes the following steps:
and step S410, adjusting the address to be allocated according to a first preset adjusting 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 for adjusting 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 requirements, such as 1, 2, 3, and the like. The first preset adjustment parameter may be the same as or different from the second preset adjustment parameter. For example, the first preset adjustment parameter is 1, 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 when the new address is within the preset address pool range and is not occupied, the new address is taken as a new address to be allocated. Then the following steps are executed: and judging whether the address to be distributed is accepted by the network card to be distributed.
In the first embodiment of the present invention, an address allocation request sent by a corresponding multi-network-card device through a network card to be allocated may be obtained. And then, according to the address allocation request and a preset allocation rule, acquiring an address to be allocated, and allocating the address to be allocated to the network card to be allocated, wherein the allocable address is an unoccupied address in a preset address pool range. The preset allocation rule may be the DHCP address allocation policy described above, or may be another method for acquiring an address to be allocated for allocation. And after the address to be allocated is allocated to the network card to be allocated, judging 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, acquiring a new address to be allocated according to a first preset adjustment rule, wherein the new address to be allocated is the address to be allocated which is obtained by executing the following steps: and judging whether the address to be distributed is accepted by the network card to be distributed. The address to be allocated is accepted by the network card to be allocated, so that the condition that the DHCP Server always allocates the same address to cause the failure of acquiring the address and the network connection can not be realized under the condition that the multi-network card equipment can not accept the allocated address is avoided, and the failure rate of the multi-network card equipment for acquiring the address is greatly reduced.
Further, referring to fig. 2, a second embodiment of the present invention provides an address allocation method, based on the embodiment shown in fig. 1, where the address allocation request includes an MAC address of a network card to be allocated, the preset generation rule includes a preset address algorithm, and step S210 includes the following steps:
step S211, generating address parameters according to the MAC address of the network card to be distributed and a preset address algorithm;
step S212, generating a preselected address according to the address information of the preset address pool and the address parameter.
Specifically, the Address allocation request may include a MAC Address (physical Address) of the network card to be allocated. Under the condition that no requirement is made on the allocated address, the MAC address of the network card to be allocated in the address allocation request and a preset address algorithm can be used. The preset address algorithm is used for calculating the MAC address to obtain corresponding address parameters, and the MAC address corresponds to the address parameters one to one. The preset address algorithm can be an SDBM hash algorithm, a DJB hash algorithm or a Lose hash algorithm and other algorithms.
For example, if the SDBM hash algorithm is applied to the MAC address, the corresponding code is:
for(j＝0,i＝0；i<hw_len；i++)
j+＝hwaddr[i]+(j<<6)+(j<<16)-j；
and after calculation is carried out according to the MAC address through a preset address algorithm, obtaining an address parameter j corresponding to the MAC address, and if the preset address pool range is 192.168.1.20-192.168.1.80, obtaining a corresponding preselected address of 192.168.1.X, wherein X is 20+ j% (80-20+1), if the address is occupied, adjusting the preselected address, such as the preselected address of 192.168.1.(X +1), until the obtained preselected address is not occupied, and taking the unoccupied preselected address as an address to be allocated. The range of the preset address pool can be modulo to avoid the calculated preselected address exceeding the range of the preset address pool. Further, for example, the code of the DJB hash algorithm is:
for(j＝0,i＝0；i<hw_len；i++)
j＝j*33+(int)hwaddr[i]；
for example, the code of the Lose hash algorithm is:
for(j＝0,i＝0；i<hw_len；i++)
j+＝(int)hwaddr[i]；
those skilled in the art will appreciate that the choice of the specific pre-selected address algorithm may be selected according to actual requirements.
In this embodiment, a preselected address is generated according to the MAC address of the network card to be allocated in the address allocation request and a preset address algorithm, and then according to the address information of the preset address pool and the address parameter. And the MAC address corresponds to the calculated address parameters one by one. Therefore, the MAC address of the network card to be distributed corresponds to the preselected address one by one, the possibility of repeated preselected addresses is reduced, and the success rate of the multi-network-card equipment for acquiring the addresses is ensured.
