With the development of the manufacturing process of the computer, the computing, storage and transmission capabilities of various terminals are greatly improved, and the improvement of the hardware capability of the equipment marks that the equipment can bear more opportunities and tasks. The hardware resources can play an important role in monitoring, controlling, intelligence and other scenes of the energy industry Internet, address management is carried out on various devices, the method is a basis for effectively planning network topology, reducing network load and improving network performance, and more importantly, the security of the network is greatly improved due to the fact that the addresses of the network devices can be managed and controlled.
The embodiment provides a network address management method of a device, which may be applied to an address management server, as shown in fig. 2, and includes the following steps:
s101, acquiring equipment network information;
for example, the device network information may include a plurality of network identifiers of a network layer where the current device performs communication transmission, such as identification information of all network cards and structured data information such as network ports corresponding to the network cards. The manner of obtaining the device network information may be to obtain personal attribute information input by a user, and bind the personal attribute as device network information with a corresponding device, or obtain a service type and a service attribute of a current device as device network information, where the service type may be used to represent a network hierarchy in which the current network device is located and a service provided, and the service attribute may be used to represent a service role represented by the current network device, for example, a service provider, a service consumer, and the like.
S102, analyzing the network information to obtain at least one network address information of the equipment;
illustratively, the network address information may include information such as the device's portal device type, network hardware interface name, network device gateway address, IP address, MAC address, netmask, ethernet address, local network identification, network global address, etc. The network information may be parsed by extracting the network information item by item according to the required network address information.
S103, calculating network address information according to a target algorithm to obtain a target network identifier;
illustratively, the target algorithm may be a one-way scattering algorithm, for example, a hash.md5 algorithm, the scattering algorithm has two functions of input and output, the input is current device network address information (such as a MAC address), and the algorithm also supports other inputs, when the input is heterogeneous, the algorithm may convert character input with any length into input with a fixed length, and output binary output with a length of 128 bits, and the security of the generated target network identifier can be effectively ensured through the one-way scattering algorithm. The target algorithm is not limited in this embodiment, and those skilled in the art can determine the target algorithm as needed. The network address information may be a MAC address capable of uniquely characterizing the device in each address information, or may be other information capable of characterizing the device.
Taking the target algorithm as MD5 algorithm as an example, four constants (a, b, c, d) and four nonlinear functions (F, G, H, I) are required for specific calculation, such as:
wherein, v is bitwise OR, not ()' is bitwise negation, and xor is bitwise XOR.
First, network address information is padded so that the length of the network address information is modulo 512 to 448, and the length of the network address information is X, that is, X mod 512=448 is satisfied. And obtaining the data length needing to be filled according to the formula. A specific padding method may be padding after the message, the padding first bit being 1 and the rest being 0. The length of the network address information is filled after the filling is finished, and the storage length which can be used for storing the network address information is 64 bits. If the length of the network address information is greater than 64, only the lower 64-bit value thereof is used. After this step is completed, the length of the final network address information is n times of an integer of 512.
The loop is performed n times according to the length of the algorithm, and the first round is performed 16 times. Each operation performs a non-linear function operation on three of a, b, c, d with the four non-linear functions mentioned above (one for each round), and then adds the result with a fourth variable. The result is then shifted to the right by an indefinite number and one of a, b, c, d is added. Finally, one of a, b, c and d is replaced by the result.
Specifically, as shown in fig. 3, input information is calculated according to a target algorithm, and a sign of the calculation end is whether sub-calculation operations are currently performed for 64 times, and each sub-operation must be performed to update a related parameter value as follows;
the update operation is as follows: t = ((a + f + gth group + k [ i ]) < < s [ i ]) + b, a = d, d = c, c = b, b = t, i = i +1.
Therefore, after each update calculation, i = i +1, it is determined whether i is smaller than 64 (i.e., whether 6 operations have been performed), and when i = =64, the result is output, and the operation is performed according to the difference in the value of i.
When i <16, f = (b & c) or (~ b & d), g = i, and then the update operation is performed.
If 32 = (b & d) or (~ d & c), g = (5 x i + 1) mod 16, then the update operation is performed.
When 48 ≧ i is greater than or equal to 32, f = b ^ c ^ d, g = (3 × i + 5) mod 16 is carried out, and then the updating operation is carried out.
When 64 ≧ i is greater than or equal to 48, f = c ^ (d or b), g = (7 ^ i) mod 16 is performed, and then the update operation is performed.
I = =64, stop, and output the result.
Where "=" is the assignment operator: i =0 means that 0 is assigned to i, i.e. i is given a value of 0;
"&" indicates the bitwise and operator, which is exemplified by: 1010b & 1100b has a value of 1000b;
"Or" represents bitwise Or operator, and specific examples are: 1010b or 1100b, as a value of 1110b;
"A" represents a bitwise XOR operator, which is specifically exemplified by: 1010b 1100b has a value of 0110b;
"to" represents a bitwise negation operator, and specific examples are as follows: the value of-1010 b is 0101b;
"<" represents a bitwise cyclic left shift operator, with specific examples: 1100b < < 3 has a value of 0110b;
"mod" represents the modulus operator, specifically exemplified by: 33 mod 16 has a value of 1;
"i = =64" is to determine whether i is equal to 64.
s [ i ] takes the value of the i +1 th number of the following array:
{ 7, 12, 17, 22, 7, 12, 17, 22, 7, 12, 17, 22, 7, 12, 17, 22,5, 9, 14, 20, 5, 9, 14, 20, 5, 9, 14, 20, 5, 9, 14, 20, 4, 11,16, 23, 4, 11,16, 23, 4, 11,16, 23, 4, 11,16, 23, 6, 10, 15,21, 6, 10, 15,21, 6, 10, 15,21, 6, 10, 15,21 }. Such as s [0] = =7, s [3] =22 and the like.
k [ i ] takes the value of the i +1 th number of the following arrays:
{ 0xd76aa478, 0xe8c7b756, 0x242070db, 0xc1bdceee, 0xf57c0faf,0x4787c62a, 0xa8304613, 0xfd469501, 0x698098d8, 0x8b44f7af,0xffff5bb1, 0x895cd7be, 0x6b901122, 0xfd987193, 0xa679438e,0x49b40821, 0xf61e2562, 0xc040b340, 0x265e5a51, 0xe9b6c7aa,0xd62f105d, 0x02441453, 0xd8a1e681, 0xe7d3fbc8, 0x21e1cde6,0xc33707d6, 0xf4d50d87, 0x455a14ed, 0xa9e3e905, 0xfcefa3f8,0x676f02d9, 0x8d2a4c8a, 0xfffa3942, 0x8771f681, 0x6d9d6122,0xfde5380c, 0xa4beea44, 0x4bdecfa9, 0xf6bb4b60, 0xbebfbc70,0x289b7ec6, 0xeaa127fa, 0xd4ef3085, 0x04881d05, 0xd9d4d039,0xe6db99e5, 0x1fa27cf8, 0xc4ac5665, 0xf4292244, 0x432aff97,0xab9423a7, 0xfc93a039, 0x655b59c3, 0x8f0ccc92, 0xffeff47d,0x85845dd1, 0x6fa87e4f, 0xfe2ce6e0, 0xa3014314, 0x4e0811a1,0xf7537e82, 0xbd3af235, 0x2ad7d2bb, 0xeb86d391 }。
and S104, generating the network address of the equipment according to any one of the target network identification and the network address information.
Illustratively, according to any one of the target network identifier and the network address information, the network address of the device may be generated in a manner that, first, the length of the required network address that can be customized is determined according to the network gateway, then, the required number of bits is selected from the target network identifier in a sequence from front to back, and the network address of the device is generated by combining the different expression forms of the different network address information and the target network identifier. Different manifestations may characterize different systems of addresses corresponding to different protocols, etc., e.g., IPv4 addresses are typically decimal, and IPv6 addresses and ARP addresses are typically 16 systems. Specifically, when the protocol type of the network address information is ipv6 and the customized length is the last 64 bits, the network address of the generating device may be in the form of ipv6 with the first 64 bits + the first 64 bits of the target network identifier forming 128 an ipv6 address. It should be noted that the target network identifier may be obtained by performing target operation on the MAC address, that is, the network address information used in the stage of generating the target network identifier may be different from the network address information used in the stage of generating the network address of the device.
With the development of internet services in the energy industry, the monitoring and control requirements of various devices are gradually increased, and the random address management mode is difficult to perform fine-grained network management and control at first, so that the gradually increased computing power of various edge devices is wasted. Meanwhile, as more and more devices in the energy industry internet are accessed, how to cooperate with network address management of different network layers becomes a problem to be solved urgently. In this scenario, the method for managing a network address of a device according to this embodiment obtains network address information of the device according to the network information of the device, and calculates the network address information according to a target algorithm to obtain a target network identifier; the network address of the device is generated according to any one of the target network identifier and the network address information, so that one-to-one correspondence between the device and the network address is realized, the device is convenient to be effectively managed, and different network addresses (IPV 6, IPV4 and the like) can be generated according to different communication protocols when the devices are communicated, so that network address management between different network layer levels is convenient to coordinate.
As an optional implementation manner of this embodiment, as shown in fig. 4, the method further includes: performing validity check on the network address of the device, including at least one of: judging whether the network address of the equipment meets the network address specification or not; it is determined whether the network address of the device exists in a pool of target network addresses.
Illustratively, the validity check includes: judging whether the currently generated network address format conforms to the definition of the relevant network standard, judging whether the network address of the equipment exists in a target network address pool or not, and avoiding invalid generation of the network address, wherein the target network address pool is determined by network address information, an address fixed prefix for representing the equipment address can be determined through a gateway address, a network mask, an Ethernet address, a local network identifier, a network global address and the like in the network address information, the rest parts are used as custom parts, different addresses can be formed by filling the custom parts differently, an address space formed by filling the different custom parts is used as the target address pool for verifying whether the generated network address is legal, and when the generated network address is not in the address pool, the network address is invalid.
The network address management method for the device provided by this embodiment ensures the feasibility, validity, and correctness of the generated network address by performing validity check on the network address of the device.
As an optional implementation manner of this embodiment, the method further includes:
when the network address of the device passes the validity check, the network address of the device is added, and the network address is allocated to the corresponding device. Further, when the network address of the device fails the validity check, an error prompt may be issued.
As an optional implementation manner of this embodiment, as shown in fig. 4, the method further includes: and receiving a network address management instruction, and performing addition/deletion/modification/query management on the network address.
Illustratively, the network address subjected to validity verification can be changed in a dynamic compiling mode, management of the network address is carried out by calling a Linux dynamic kernel compiling method, management aiming at the current network address is supported, and the management comprises modification, addition, inquiry and deletion, and one network port can bear a plurality of virtual network addresses, including addresses of different protocol versions and addresses of the same protocol.
The adding management is to add a network port for a specific fixed hardware network device, and the query is to monitor whether an added network address already exists. When the deletion management is performed, when only one address exists in the network, the operation of deleting the network is invalid.
As an optional implementation manner of this embodiment, the method further includes: and acquiring equipment network information, analyzing the network information, and verifying whether a network address management instruction is completed or not.
For example, the analyzing of the network information and the verifying whether the network address management instruction is completed may be analyzing the network information of the device to obtain at least one type of network address information of the device, and verifying whether the network address information of the device is consistent with the content represented in the network address management instruction, for example, when the modification instruction in the network address management instruction is to modify the address of the device a from the address 1 to the address 2, the verifying at this time is to determine whether the current network address information of the device is the address 2, and if the modification instruction is the address 2, the modifying instruction is completed.
As an optional implementation manner of this embodiment, as shown in fig. 4, the step of calculating the network address information according to the target algorithm to obtain the target network identifier is replaced with: receiving user self-defined information, and calculating the user self-defined information according to a target algorithm to obtain a target network identifier; or receiving user self-defined information, and taking the self-defined information as a target network identifier.
Illustratively, the trigger mode for generating the target network identifier includes a client trigger and a server trigger. The server side triggers the network address by analyzing the network information to obtain at least one network address information of the equipment, and then the network address information is calculated according to a target algorithm to obtain a target network identifier. The client information triggers to generate a target network identifier, a user needs to provide user-defined information, such as user personal attribute information, to the address management server in advance, the user-defined information is calculated and then used as the target network identifier, and the user-defined information can also be directly input and used as the target network identifier. And the address management server allocates a network address which is unique in the whole network to the user according to the user-defined information.
As an optional implementation manner of this embodiment, as shown in fig. 4, the method further includes: and receiving the user-defined equipment network address.

s202, when the path information corresponding to the data transmission request is stored locally, data transmission is carried out according to the path information.
Exemplarily, in the data transmission process, a routing entry needs to be requested from an address management server in the console, and the server generates a data transmission path (on-demand routing) according to a routing control protocol, where the path information includes network addresses of various routing nodes, and the network addresses are generated by the network address management method of the device in the above embodiment, and details are not repeated.
