It should be understood that the numbers used in this way are interchangeable where appropriate so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to these processes, methods, products, or apparatus.

[0026] In addition, it should be noted that in the technical solution of the present invention, the collection, storage, use, processing, transmission, provision and disclosure of relevant data such as subnets and network segments involved are in compliance with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0027] Figure 1 This is a flow chart of a subnet allocation method provided according to an embodiment of the present disclosure. This method is applicable to the situation of how to flexibly allocate subnets to a large network segment, and is particularly applicable to the situation of allocating IP subnets of various sizes in a large IP network segment. This method can be executed by a subnet allocation device, which can be implemented in software and / or hardware and can be integrated into an electronic device that carries the subnet allocation function, such as a server. Figure 1 As shown, the subnet allocation method of this embodiment may include:

[0028] S101, determining a network segment to be allocated, a subnet allocation unit of the network segment to be allocated, and a required size of a required subnet.

[0029] In this embodiment, the network segment to be allocated refers to the network segment used for subnet allocation, for example, it can be a large IP network segment; optionally, the network segment to be allocated includes at least one subnet allocation unit. The subnet allocation unit refers to the smallest subnet allowed to be allocated in the network segment to be allocated. The so-called required subnet refers to the subnet that needs to be allocated. The so-called required size refers to the subnet size of the required subnet. It should be noted that the required size is greater than the network segment size of the network segment to be allocated; the network segment size refers to the subnet size of the network segment to be allocated. For example, if the network segment to be allocated is 10.0.0.0 / 8, that is, the network segment size is 8, and the binary representation of IP is 32 bits, then 2^24 IP addresses can be allocated in the network segment to be allocated, that is, there is 24 bits of available space for subnet allocation.

[0030] It should be noted that the subnet size is expressed in the number of bits in the subnet's IP network number. For example, the subnet size of IP subnet 10.1.2.0 / 24 is 24, and the subnet size of IP subnet 10.1.0.0 / 16 is 16.

[0031] Specifically, an IP network segment can be selected based on service requirements as the network segment to be allocated. Furthermore, a subnet allocation unit within the network segment to be allocated can be determined based on the network segment to be allocated and / or service requirements. Furthermore, the required size of the requested subnet in the subnet allocation request is obtained. A subnet allocation request is a request for initiating subnet allocation.

[0032] S102: Allocate the network segments to be allocated according to the subnet allocation unit and the required size to obtain a target subnet corresponding to the required subnet.

[0033] In this embodiment, the target subnet refers to the IP subnet allocated to the demand subnet from the to-be-allocated network segment. It should be noted that the subnet size of the target subnet may be larger than the required size of the demand subnet, or may be smaller than the required size of the demand subnet.

[0034] In an optional manner, based on the demand size of the demand subnet, an appropriate number of subnet allocation units are determined from the network segment to be allocated, and these subnet allocation units are used as target subnets corresponding to the demand subnet.

[0035] The technical solution provided by the disclosed embodiments determines the network segment to be allocated, the subnet allocation unit for the segment, and the required size of the desired subnet. Then, based on the subnet allocation unit and the required size, the segment to be allocated is allocated to obtain the target subnet corresponding to the required subnet. This technical solution, by introducing the subnet allocation unit for subnet allocation, can rationally allocate IP subnets of different sizes, thereby improving IP utilization within the IP pool.

[0036] Figure 2 This is a flow chart of another subnet allocation method provided according to an embodiment of the present disclosure. Based on the above embodiment, this embodiment further optimizes "allocating the to-be-allocated network segments according to the subnet allocation unit and the demand size to obtain the target subnet corresponding to the demand subnet" and provides an optional implementation scheme. Figure 2 As shown, the subnet allocation method of this embodiment may include:

[0037] S201, determining a network segment to be allocated, a subnet allocation unit of the network segment to be allocated, and a required size of a required subnet.

[0038] S202: Determine the required number of units of the subnet allocation unit according to the required size and the unit size of the subnet allocation unit.

[0039] In this embodiment, the required number of units refers to the number of subnet allocation units required by the demand subnet.

[0040] In an optional manner, the required size may be divided by the unit size of the subnet allocation unit, the obtained quotient may be rounded up, and the obtained result may be used as the required number of units of the subnet allocation unit.

[0041] S203 , allocating the network segments to be allocated according to the required number of units and the subnet allocation unit, and obtaining the target subnet corresponding to the required subnet.

[0042] In an optional manner, a required number of subnet allocation units is determined from the network segment to be allocated, and used as the target subnet corresponding to the required subnet.

[0043] The technical solution provided by the embodiments of the present disclosure determines the network segment to be allocated, the subnet allocation unit of the network segment to be allocated, and the required size of the required subnet. Then, based on the required size and the unit size of the subnet allocation unit, the required number of units of the subnet allocation unit is determined. Then, based on the required number of units and the subnet allocation unit, the network segment to be allocated is allocated to obtain the target subnet corresponding to the required subnet. The above technical solution allocates the network segment to be allocated based on the required number of units and the subnet allocation unit to obtain the target subnet, which can quickly and reasonably obtain the target subnet corresponding to the required subnet.

[0044] Based on the above embodiment, as an optional method of the present disclosure, the unit requirement quantity of the subnet allocation unit is determined according to the demand size and the unit size of the subnet allocation unit, including: if the demand size is greater than or equal to the unit size, then the unit requirement quantity of the subnet allocation unit is determined to be 1; if the demand size is less than the unit size, then the unit requirement quantity of the subnet allocation unit is determined according to the difference between the unit size and the demand size.

[0045] Specifically, the demand size and the unit size can be compared, and the required number of units for the subnet allocation unit can be determined based on the comparison result. For example, if the demand size is greater than or equal to the unit size, the required number of units for the subnet allocation unit is determined to be 1. If the demand size is less than the unit size, the difference between the unit size and the demand size is determined, and the difference is raised to the power of 2 as the required number of units for the subnet allocation unit.

[0046] It is understandable that determining the required number of units of the subnet allocation unit by comparing the unit size of the subnet allocation unit with the required size of the required subnet can improve the accuracy of determining the required number of units, thereby facilitating subsequent allocation of the to-be-allocated network segments.

[0047] On the basis of the above embodiments, as an optional method of the present disclosure, the network segment to be allocated is allocated according to the unit demand quantity and the subnet allocation unit to obtain the target subnet corresponding to the demand subnet, including: multiplying the unit demand quantity and the unit size of the subnet allocation unit to obtain the target size of the target subnet; determining the subnet of the target size from the network segment to be allocated as the target subnet corresponding to the demand subnet.

[0048] The target size refers to the subnet size of the target subnet.

[0049] Specifically, the unit requirement quantity can be multiplied by the unit size of the subnet allocation unit, and the product can be used as the target size of the target subnet. Then, starting from the low-order address in the network segment to be allocated, a subnet of the target size can be determined as the target subnet corresponding to the requirement subnet.

[0050] It is understandable that by determining the target subnet through the subnet allocation unit and the required number of units, a target subnet that meets the required subnet can be allocated without occupying too many other IP addresses in the network segment to be allocated.

[0051] Based on the above embodiment, a specific example is provided. If 10.0.0.0 / 8 (decimal) is selected as the network segment to be allocated, i.e., the large IP network segment, and the unit size of the subnet allocation unit of the network segment to be allocated is determined to be 24, then if a request is made to allocate an IP subnet with a required size of 24 (i.e., the demand subnet), 10.0.0.0 / 24 will be allocated; if a request is made to allocate an IP subnet with a required size of 22 (i.e., the demand subnet), 10.0.4.0 / 22 will be allocated; if a request is made to allocate an IP subnet with a required size of 26 (i.e., the demand subnet), 10.0.1.0 / 26 will be allocated.

[0052] Figure 3 This is a flow chart of another subnet allocation method provided according to an embodiment of the present disclosure. Based on the above embodiment, this embodiment further optimizes "allocating the to-be-allocated network segments according to the unit demand quantity and the subnet allocation unit to obtain the target subnet corresponding to the demand subnet" and provides an optional implementation scheme. Figure 3 As shown, the subnet allocation method of this embodiment may include:

[0053] S301, determining a network segment to be allocated, a subnet allocation unit of the network segment to be allocated, and a required size of a required subnet.

[0054] S302: Determine the required number of units of the subnet allocation unit according to the required size and the unit size of the subnet allocation unit.

[0055] S303: Determine the allocation status of the subnet allocation unit.

[0056] In this embodiment, the allocation status refers to whether the subnet allocation unit has been allocated. Optionally, the allocation status includes unallocated and allocated. It should be noted that a bitset can be used to record the allocation status of each subnet allocation unit in the network segment to be allocated.

[0057] Specifically, the allocation status of each subnet allocation unit in the to-be-allocated network segment may be determined from the bitset.

[0058] S304: Allocate the network segments to be allocated according to the required number of units, the subnet allocation unit, and the allocation status, and obtain the target subnet corresponding to the required subnet.

[0059] An optional method is to first determine that the allocation status of the subnet allocation units in the network segment to be allocated is unallocated subnet allocation units, then multiply the unit demand quantity by the unit size of these subnet allocation units, and use the product as the target size of the target subnet. Then, from the unallocated subnet allocation units in the network segment to be allocated, determine a subnet of the target size as the target subnet corresponding to the demand subnet.

[0060] The technical solution provided by the disclosed embodiments determines the network segment to be allocated, the subnet allocation unit for the network segment to be allocated, and the required size of the required subnet. Based on the required size and the unit size of the subnet allocation unit, the required number of units for the subnet allocation unit is determined, and the allocation status of the subnet allocation unit is determined. Based on the required number of units, the subnet allocation unit, and the allocation status, the network segment to be allocated is allocated to obtain the target subnet corresponding to the required subnet. This technical solution, which introduces the subnet allocation unit and its allocation status to perform subnet allocation, can quickly and accurately obtain the desired target subnet without the problem of duplicate subnet allocation.

[0061] On the basis of the above embodiments, as an optional method of the present disclosure, the network segment to be allocated is allocated according to the unit demand quantity, the subnet allocation unit and the allocation status to obtain the target subnet corresponding to the demand subnet, including: using the multiple of the unit demand quantity as the index, searching from the low-order side of the address of the network segment to be allocated, and determining the continuous unit demand quantity subnet allocation units with the allocation status of unallocated; and forming the target subnet corresponding to the demand subnet by the continuous unit demand quantity subnet allocation units.

[0062] Specifically, using the multiple of the required number of units as the index, start searching from the address position side of the network segment to be allocated, that is, search from the low position to the high position in the bitset, and find the required number of consecutive subnet allocation units with an allocation status of unallocated, that is, the required number of consecutive unallocated subnet allocation units, and group these consecutive subnet allocation units into the target subnet corresponding to the required subnet.

[0063] It can be understood that starting subnet allocation from the low-order side of the address in the to-be-allocated network segment can ensure that the allocated IP subnets are concentrated on the high-order side of the address in the to-be-allocated network segment, which is conducive to the future contraction of large network segments.

[0064] Based on the above embodiment, as an optional manner of the present disclosure, the method further includes: updating the allocation status of the subnet allocation unit corresponding to the target subnet to allocated.

[0065] Specifically, after the target subnet is allocated, the allocation status of the subnet allocation unit corresponding to the target subnet is updated to allocated in the bitset.

[0066] It is understandable that updating the allocation status of the subnet allocation unit corresponding to the target subnet to allocated can facilitate subsequent allocation of other subnets to avoid duplicate allocation of subnets.

[0067] Based on the above embodiment, as an optional method of the present disclosure, it also includes: when a subnet recycling request is identified, determining the subnet to be recycled; updating the allocation status of the subnet allocation unit corresponding to the subnet to be recycled to unallocated to complete the subnet recycling.

[0068] The subnet reclaim request is a request for reclaiming a subnet; optionally, the subnet reclaim request includes a subnet to be reclaimed. The so-called subnet to be reclaimed is a subnet that needs to be reclaimed.

[0069] Specifically, when a subnet recycling request is identified, the subnet to be recycled is determined from the subnet recycling request, and then the allocation state of the subnet allocation unit corresponding to the subnet to be recycled is updated to unallocated in the bitset to release the corresponding subnet space and complete the subnet recycling.

[0070] It is understandable that by updating the allocation status of the subnet allocation unit of the subnet to be reclaimed to unallocated, the subnet reclaim can be completed quickly, thereby achieving the reduction of the large IP network segment.

[0071] Figure 4 This is a schematic diagram of the structure of a subnet allocation device provided according to an embodiment of the present disclosure. This embodiment is applicable to the situation of how to flexibly allocate subnets to a large network segment, and is particularly applicable to the situation of allocating IP subnets of various sizes in a large IP network segment.

[0082] Using the multiple of the required number of units as the index, search from the low-order side of the address of the network segment to be allocated, and determine the required number of consecutive subnet allocation units with the allocation status as unallocated;
