Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings. The particular methods of operation in the method embodiments may also be applied to apparatus embodiments or system embodiments. In the description of the present application, the term "plurality" means two or more unless otherwise specified.
To facilitate understanding of the present application, some terms or nouns referred to in the present application are explained below.
One, IP section, sub IP section
1. IP section
An IP segment refers to a continuous IP composed of a plurality of continuous IPs. For example, 122.102.80.2-122.102.80.200 are IP segments that include 199 consecutive IPs.
Wherein, an IP is composed of four parts, which are respectively called A section, B section, C section and D section in the application. Such as for IP: 122.102.80.2, 122 for segment A, 102 for segment B, 80 for segment C, and 2 for segment D. An IP block is also understood to mean a continuous IP consisting of a plurality of IPs having the same A, B and C blocks and different and continuous D blocks.
2. sub-IP section
The sub-IP segment is a continuous IP composed of a plurality of continuous IPs in one IP segment, such as the following IP segments: 122.102.80.2-122.102.80.200, examples of which sub-IP segments are: 122.102.80.2-122.102.80.20, the sub-IP section includes 19 consecutive IPs.
Type of network device
In the present application, the type of network device refers to the type of device to which an IP address is to be assigned. For example, the type of network device may be a switch, server, wireless terminal, etc.
Third, the relation between the type of network device and IP section
In the application, the IP sections are divided according to the types of the network equipment, namely, one type of network equipment preferentially uses a sub-IP section corresponding to the type of the network equipment in one IP section.
For example, for an IP segment: 122.102.80.2-122.102.80.200, can be agreed in advance: the sub IP sections 122.102.80.2-122.102.80.20 are corresponding to switches, and the sub IP sections 122.102.80.21-122.102.80.200 are corresponding to servers. This example shows that: when an IP address is allocated to the switch, preferably selecting an IP from 122.102.80.2-122.102.80.20 to allocate to the switch; when allocating an IP address to a server, an IP address is preferably selected from 122.102.80.21 to 122.102.80.200 and allocated to the server.
For another example, for the IP segments 122.102.80.2-122.102.80.200, it can be agreed in advance: the sub IP sections 122.102.80.2-122.102.80.20 correspond to switches, the sub IP sections 122.102.80.21-122.102.80.170 correspond to servers, and the sub IP sections 122.102.80.171-122.102.80.200 correspond to wireless terminals.
The length of the sub IP segment corresponding to one type of network device may be determined according to the type of network device and the length of the IP segment.
For example, if the type of the network device includes servers and switches, a certain IP segment is 122.102.80.2 to 122.102.80.200, and the number of the servers is usually greater than the number of the switches, when dividing the sub-IP segments, the length of the sub-IP segment corresponding to the server may be greater than the length of the sub-IP segment corresponding to the switch, for example, the sub-IP segment corresponding to the switch is 122.102.80.2 to 122.102.80.20, and the sub-IP segment corresponding to the server is 122.102.80.21 to 122.102.80.200. Of course, the lengths of the sub IP segments corresponding to different network devices may be adjusted according to actual needs, and the present application is not particularly limited. When the sub-IP segments are actually divided, the division may be performed according to the number of the IPs in the IP segment, specifically, when the number of the IPs in the IP segment is greater than a threshold, a sub-IP segment with a first length is allocated to the first type of network device, and when the number of the IPs in the IP segment is not greater than the threshold, a sub-IP segment with a second length is allocated to the first type of network device, where the first length is different from the second length.
Fig. 1 is a schematic flow chart of an internet protocol IP address allocation method provided by the present application, and the method may be executed by a cloud device, where the cloud device may be, for example, a cloud control server, a computer, a notebook computer, and the like. As shown in fig. 1, the method includes:
And the number of the unallocated IPs in the IP section to be allocated is greater than or equal to the number of the network equipment. For example, if the network devices needing to allocate the IPs are 10 switches, the IP segments 122.102.80.2-122.102.80.200 are allocated with the IPs of 122.102.80.2 and 122.102.80.3, the number of unallocated IPs in the IP segment is 197, that is, 122.102.80.4-122.102.80.200, and the IP segments 122.102.80.2-122.102.80.200 satisfy that the number of unallocated IPs is greater than or equal to the number of the network devices, so the IP segments 122.102.80.2-122.102.80.200 can be selected as the IP segments to be allocated.
And 102, determining a first sub-IP section corresponding to the type of the network equipment in the IP section to be distributed according to the type of the network equipment.
And 103, allocating the IP in the IP section to be allocated to the network equipment according to the number of the network equipment and the number of the unallocated IP in the first sub-IP section.
In a possible implementation manner, the step 101 may specifically include: and if the IP section of the first type exists in the candidate IP sections, acquiring one IP section in the IP sections of the first type as the IP section to be distributed. The candidate IP segment may be a plurality of C segments different IP segments, such as candidate IP segment a: 122.102.80.2-122.102.80.200, candidate IP segment B: 122.102.81.2-122.102.81.200, candidate IP segment C: 122.102.82.2-122.102.82.200, etc. The number of unassigned IPs in the sub-IP section corresponding to the type of the network device in the IP section of the first type is greater than or equal to the number of network devices. For example, the sub IP segments corresponding to the switch in the three IP segments listed above are: candidate IP segment a: 122.102.80.2-122.102.80.20, candidate IP segment B: 122.102.81.2-122.102.81.20, candidate IP segment C: 122.102.82.2-122.102.82.20, wherein the unallocated IP in the sub-IP section corresponding to the switch in the candidate IP section A is 122.102.80.18-122.102.80.20, the unallocated IP in the sub-IP section corresponding to the switch in the candidate IP section B is 122.102.80.11-122.102.80.20, and the unallocated IP in the sub-IP section corresponding to the switch in the candidate IP section C is 122.102.80.4-122.102.80.20, then when the number of switches needing to allocate IP is 15, only the candidate IP section C in the candidate IP section A, the candidate IP section B and the candidate IP section C is the IP section of the first type, so the candidate IP section C is selected as the IP section to be allocated.
In a possible implementation manner, if multiple different network device types exist at the same time, for example, the types of the network devices include a switch and a server, in step 102, according to the types of the network devices, the first sub-IP segment corresponding to the type of the network device in the IP segment to be allocated is determined, specifically, according to the type of each network device, the first sub-IP segment corresponding to each network device type is determined respectively. Further, according to the type of the network device, a first sub-IP segment corresponding to the switch in the IP segment to be allocated is preferentially determined for the switch, and then a first sub-IP segment corresponding to the server in the IP segment to be allocated is determined for the server. In other words, an IP can be planned and allocated to the network device according to the importance level corresponding to the type of the network device, an IP is reserved for the device with high importance preferentially, an IP is planned for the special server, and an IP is planned for the common server finally. For example, for the same segment, for IP segment: 122.102.80.2-122.102.80.200, a certain number of IP can be planned and reserved for core equipment such as an exchanger preferentially as the first sub-IP section corresponding to the exchanger, such as 122.102.80.2-122.102.80.20; planning a first sub IP section corresponding to the server for other network equipment such as the server, such as 122.102.80.21-122.102.80.200; it is considered that if there are other special servers, such as load balancing servers, a part of the IP may be reserved in the first sub-IP segment, such as 122.102.80.21-122.102.80.200, to the load balancing server as the first sub-IP segment, such as 122.102.80.21-122.102.80.40, corresponding to the load balancing server, and then the first sub-IP segment, such as 122.102.80.41-122.102.80.200, corresponding to the other servers may be planned.
In a possible implementation manner, the number of unallocated IPs in the first sub-IP segment is less than or equal to the number of unallocated IPs in sub-IP segments corresponding to the type of the network device in other IP segments in the first type of IP segment. By taking the candidate IP segment a, the candidate IP segment B, and the candidate IP segment C listed above as an example, when the number of switches to be allocated is 5, the candidate IP segment B and the candidate IP segment C are both IP segments of the first type, and when the IP segment to be allocated is determined, the IP segments corresponding to the switches in the candidate IP segment B are less unassigned, so that the candidate IP segment is selected as the IP segment to be allocated. Therefore, the residual unallocated IP quantity in the IP section is less, and the IP section resource utilization is more sufficient.
After selecting an IP segment of the first type as the IP segment to be allocated by the method, the step 103 may specifically include: and from the first IP in the first sub-IP section, sequentially allocating IPs to the network devices according to the ascending order of the IPs, wherein one network device is allocated with one IP. And allocating the IP before the first IP in the first sub-IP section, and not allocating the first IP in the first sub-IP section and the IP after the first IP. And at the time of allocation, the first IP also needs to be allocated to the network device. Taking 5 network devices needing to be allocated with IP as switches, and the selected IP section to be allocated as the candidate IP section B as an example, the first IP is 122.102.81.12, that is, the allocated IP in the first sub-IP sections 122.102.81.2-122.102.81.20 is 122.102.81.2-122.102.81.11. Then, when allocating IPs for 5 switches, the following 5 IPs are selected in order: 122.102.81.12, 122.102.81.13, 122.102.81.14, 122.102.81.15, 122.102.81.16.
By the method, for one type of network equipment, the network equipment is distributed to the corresponding sub-IP sections, and the IP in the corresponding sub-IP sections is distributed to each network equipment in sequence, so that management operations such as IP inquiry and the like can be conveniently carried out at the later stage.
Of course, when the step 101 selects an IP segment to be allocated, there may be a possibility that the first type IP segment does not exist in the candidate IP segments. In this possibility, the step 101 may specifically include: and acquiring one IP section in the second type of IP sections as the IP section to be distributed. The number of unallocated IPs in the sub-IP section corresponding to the type of the network equipment in the IP section of the second type is less than the number of the network equipment, and the number of unallocated IPs in the IP section of the second type is greater than or equal to the number of the network equipment. Continuing with the above list of candidate IP segment a, candidate IP segment B, and candidate IP segment C, assume that the number of switches to be allocated at this time is 20. None of the candidate IP segment a, candidate IP segment B and candidate IP segment C are IP segments of the first type. And assuming that 122.102.80.21-122.102.80.180 of the candidate IP segment A have been fully allocated to the server, 122.102.81.21-122.102.81.197 of the candidate IP segment B have been fully allocated to the server, and 122.102.82.21-122.102.82.199 of the candidate IP segment C have been fully allocated to the server, only the candidate IP segment A satisfies the definition of the second type of IP segment, and thus, the candidate IP segment A is selected as the IP segment to be allocated determined in step 101.
Similarly, in a possible implementation manner, when a plurality of candidate IP segments are all IP segments of the second type, one of the IP segments of the second type with the smallest unallocated IP number is selected as the IP segment to be allocated, so that the remaining unallocated IP number in the IP segment is smaller, and the IP segment resources are more fully utilized.
In a possible implementation manner, the number of the network devices is M, the IPs before the first IP in the first sub-IP segment are all allocated, and the IPs after the first IP and the first IP in the first sub-IP segment are not allocated. The step 103 may specifically include: and sequentially allocating IPs to the network equipment from the first IP in the first sub-IP section according to the ascending order of the IPs, wherein N network equipment in the network equipment is respectively allocated with one IP, N is the number of the unallocated IPs in the first sub-IP section, and N is a positive integer smaller than M. And sequentially allocating IPs to other M-N network devices in the network devices according to the descending order of the IPs from the last IP in a second sub-IP section in the IP section to be allocated, wherein the M-N network devices are respectively allocated with one IP, and the type of the network device corresponding to the second sub-IP section is different from that of the network device corresponding to the first sub-IP section. Taking 20 switches as network devices needing to be allocated with the IP, and taking the selected IP segment to be allocated as the candidate IP segment a, the first IP is 122.102.80.19, and the IPs from 122.102.80.19 in the sub-IP segment corresponding to the switch are sequentially allocated to the switch, that is, 122.102.80.19 and 122.102.80.20 are allocated to the switch. Then 18 switches have not been allocated to the IP, and another sub-IP segment of the candidate IP segment is 122.102.80.21-122.102.80.200, 18 IPs are selected from 122.102.80.200 from back to front to be allocated to the remaining switches which are not allocated to the IP, that is, 122.102.80.200-122.102.80.183 are allocated to the switches.
By the method, all the IPs of the first sub-IP section in the final IP section are distributed to the same type of network equipment, and the IPs at the tail end of the second sub-IP section are also distributed to the network equipment of the type. Specifically, if the types of network devices include a switch and a server, a part of the IP at the beginning and a part of the IP at the end in one IP segment are each assigned to the switch, and the IP in the middle are each assigned to the server. By the IP allocation method, management operations such as IP inquiry and the like can be conveniently carried out at the later stage. In addition, the switch and the server executing the same network service are distributed in the same network segment, so that the network service quality can be improved.
In one possible implementation, if neither an IP segment of the first type nor an IP segment of the second type exists in the candidate IP segments, a new IP segment that can satisfy the condition is enabled. Specifically, a new IP segment may be obtained for registration application to a network operator, or an intranet IP segment may be established by itself. Because it takes a certain time to register a new IP segment with a network operator, generally, an intranet IP segment is used first to allocate an IP to a network device, so that the network device can be put into use more quickly, and when an IP segment to be allocated that meets the conditions is available, the intranet IP can be replaced with an available IP in batches. The application is not particularly limited as to how the new IP segment is obtained.
In a possible implementation manner, if multiple network operators have IP segments that meet allocation requirements, the IP of each operator needs to be allocated when each network device is allocated. This may allow the network device to serve more users.
In yet another possible implementation, if one of the plurality of network operators does not satisfy the allocation requirement, all the network operators are not allocated. The scheme can make the services of all operators on line simultaneously.
In the following, a specific example is further described in the present application, and fig. 2 is a method for allocating an IP of a network device, as shown in fig. 2, the method includes:
in step 201, a sub-IP section is divided for each IP section.
For the specific dividing method, reference may be made to the foregoing description on how to determine the length of the sub-IP segment, and details are not described herein again.
At step 202, the number of network devices that need to be allocated is determined.
Specifically, step 203 may include: and determining the number of unallocated IPs in the sub-IP section corresponding to the network equipment in each IP section and the number of unallocated IPs in each IP section.
The order of the IP segments may be sorted according to the size of the C segment, or sorted according to the number of unassigned IPs. This is not particularly limited by the present application.
If yes, go to step 206, otherwise go to step 207.
Wherein, allocating the IP to the network device according to the first rule may specifically include: and from the first IP in the first sub-IP section, sequentially allocating IPs to the network devices according to the ascending order of the IPs, wherein one network device is allocated with one IP. Wherein the first sub-IP segment refers to a sub-IP segment corresponding to the type of the network device. The IP before the first IP in the first sub-IP section is allocated, and the IP in the first sub-IP section and the IP after the first IP are not allocated.
If so, go to step 208, otherwise go to step 209.
And step 208, allocating the IP to the network equipment according to the second rule.
Wherein, allocating the IP to the network device according to the second rule may specifically include: and from the first IP in the first sub-IP section, sequentially allocating IPs to the network devices according to the ascending order of the IPs, wherein one network device is allocated with one IP. All network devices are not allocated IP because the number of unallocated IPs in the first sub-IP section from the first IP is insufficient. Therefore, it is further required to perform that, starting from the last IP in the second sub-IP segment in the IP segment to be allocated, the IPs are sequentially allocated to other network devices that are not allocated with IPs in the network devices according to the descending order of the IPs. And the type of the network equipment corresponding to the second sub-IP section is different from the type of the network equipment corresponding to the first sub-IP section.
Step 209 determines whether there are any IP segments that have not been determined.
If yes, returning to step 204, otherwise, indicating that all IP sections do not meet the allocation requirement and not allocating IP for the network equipment.
The method for allocating the network device IP shown in fig. 2 is the same as the method process type shown in fig. 1, and reference may be made to the specific explanation in fig. 1, which is not repeated herein.
