Description

An address configuration method, device and equipment

technical field

The invention relates to the field of data communication, in particular to an address configuration method, device and equipment.

Background technique

In a data communication network system, data transmission and reception are required between various devices in the system. This data transmission and reception is carried out in a network based on IP and MAC addresses, so it is necessary to use a method to determine and set The IP address and MAC address of each device in the system. In a common solution, the IP address allocation within the network system adopts the DHCP (Dynamic Host Configuration Protocol) method.

DHCP provides addresses and configuration parameters for hosts in the network. It is based on the mode of client and server. The working principle of DHCP and the process of requesting IP are as follows:

1. The host sends a DHCP discovery broadcast packet to search for a DHCP server on the network;

2. After the DHCP server receives it, it sends a unicast packet to the host, including IP address, MAC address, domain name information and address lease period;

3. The host sends a DHCP request to formally request the server to assign the provided IP address;

4. The DHCP server sends a DHCP confirmation to the host to confirm the host's request.

The advantage of configuring the host address by the DHCP server is that it reduces the configuration and deployment time of the device, reduces the possibility of configuration errors, and can centrally manage the host IP; however, it is precisely this way of use, which also has the following disadvantages:

Randomness of IP address: The user's IP address is randomly assigned, which is uncertain, and it is difficult for the user to access the host; if the IP address of the host changes frequently, it is also difficult to implement network management strategies based on the network IP address;

Changes in access rights: If the user's access rights are divided based on IP addresses, the access rights will vary with different IP addresses.

If there are multiple DHCP servers in the network, IP address conflicts may occur

If there are non-DHCP hosts in the network, the DHCP server cannot find them;

Since the IP address assignment depends on the normal operation of the external DHCP server, once the DHCP server is running abnormally, it will directly affect the IP address assignment of devices in the network, thereby affecting the services of users.

detailed description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

As shown in Figure 1, an embodiment of the present invention provides an address configuration method, including:

Step 11, obtaining the location information of the device in the network, the location information can uniquely identify the device;

Step 12, converting the location information into location information parameters;

Step 13, converting the location information parameter into an IP address and a MAC address of the device;

Step 14, automatically assigning the IP and MAC address to the device.

This embodiment of the present invention obtains the location information of the device in the network, and the location information can uniquely determine the device; converts the location information into a location information parameter; converts the location information parameter into the IP address of the device and MAC address; automatically assigning said IP and MAC address to said device. The method adopted in the embodiment of the present invention does not depend on an external DHCP server, and the acquired IP and MAC addresses are determined without randomness. It also avoids the possible IP address conflict and the problem of not being able to obtain the address.

Wherein, in a specific embodiment of the present invention, on the basis of the above-mentioned steps 11-14, wherein, the location information can be obtained through various methods such as configuration files and location positioning; the location information can include: A set of location data within a network that identifies its physical location, the set of location data uniquely identifying the device. Of course, the location information is not limited to the physical location information of the device in the network, and all information that can represent the location of the device in the network can be used as the location information of the device. For example: for a distributed equipment frame, it can be divided into office number, rack number, frame number, slot number, and CPU number; for an area, it can be divided into province, city, district, road (street), number ; For a family, if there are multiple houses, they can be divided into households, rooms, and equipment in the rooms.

Wherein, in another specific embodiment of the present invention, on the basis of the above-mentioned steps 11-14, the above-mentioned step 12 may specifically include: respectively mapping the set of location data into a location information parameter to obtain a set of location information parameter. Specifically, a number value is given for each field of the location information. For example, for a distributed equipment chassis, it has office number, rack number, chassis number, slot number, and CPU number values, which can be directly mapped As a location information parameter; and for an area, such as No. X, Road (Street) D, District C, City B, Province A, it is necessary to number each province, city, district, road (street), and No. X to map out a set of Location information parameter value; for a family, it can be mapped to values such as household number, room number, and device number. For the position information parameter, its parameter range is a continuous linear parameter. For the location information parameter, there needs to be a fixed parameter to indicate the number of the local area network where the IP address is located, that is, the network number. This network number can be multiplexed with the location information parameter as an input parameter, and the function of the network number is mainly to distinguish and isolate each network.

Wherein, in another specific embodiment of the present invention, on the basis of including the above steps 11-14, the above step 13 may specifically include:

Step 131, using the location information parameter as the conversion factor of the IP address field, and converting it into the IP address of the device according to the conversion factor and the IP address conversion algorithm corresponding to each conversion factor; and

Step 132, using the location information parameter as a conversion factor of the MAC address field, and converting it into a MAC address of the device according to the conversion factor and a MAC address conversion algorithm corresponding to each conversion factor.

Wherein, step 131 includes:

Step 1311, divide the location information parameter into 4 conversion factors, each conversion factor corresponds to a field of the IP address, and each conversion factor corresponds to an IP address conversion algorithm;

Step 1312, converting each conversion factor into a field of the IP address according to the IP address conversion algorithm corresponding to the conversion factor;

Step 1313, combine the four fields to obtain the IP address of the device.

Taking IPv4 as an example, the existing IP address is 32 bits, and every 8 bits is a field, and the 32-bit IP address is composed of four field values. The four-field value of the IP address, each field value corresponds to an address conversion algorithm, the location information parameter is used as the input parameter of the conversion algorithm, and one or more input parameters are used as the conversion factor of this algorithm, and a piece of IP address value is obtained after conversion, IP address The four-field values form a 32-bit IP address. Obviously, the address conversion algorithm corresponding to the value of each segment of the IP address is a continuous linear algorithm, that is, according to the transformation of the input parameters, the value obtained through the conversion algorithm should change continuously.

Considering that the valid range of the value of the first segment of IPv4 is within the range of 1 to 126 and 128 to 223 in decimal, the valid range of the values of segment 2, 3, and 4 must be between 0 and 255 in decimal. For each conversion factor, that is, the location information parameter obtained through mapping, its value range is also within the four-segment value range of IPv4. Similarly, the range of the value obtained by the conversion factor through the conversion algorithm is also within the four-stage value range of IPv4.

For a 32-bit IP address, it can be divided into two parts. The former part is the network address of the IP address, and the latter part is the host address of the IP address. The network address and the host address are divided by the subnet mask, for example, for IP The address A.B.C.D, the subnet mask is 255.255.255.0, the first three bytes A.B.C are its network address, and the last byte D is its host address.

Further, after the above step 1313, it also includes:

Step 1314, obtain the subnet mask of the IP address according to the network number in the location information.

The present invention divides the network address and the host address, that is, the setting of the subnet mask is determined according to the network number in the location information. For example, if a family is set, the IP address obtained by its conversion algorithm is: account number. Room No. 1. Equipment No., each room is a local area network, its network No. and room No. can be set to be the same, then its subnet mask is 255.255.0.0, and the account No. and room No. are its network addresses, 1 and the device number are its host addresses. If each room has multiple LANs, the network number of each LAN is used as an input parameter, and the IP address obtained by the conversion algorithm is account number.room number.network number.equipment number, then Its subnet mask is 255.255.255.0. Here the subnet mask is set according to its network range.

Wherein, in a specific embodiment of the present invention, the above step 132 includes:

Step 1321, divide the location information parameter into 6 conversion factors, each conversion factor corresponds to a field of the MAC address, and each conversion factor corresponds to a MAC address conversion algorithm;

Step 1322, converting each conversion factor into a field of the MAC address according to the MAC address conversion algorithm corresponding to the conversion factor;

Step 1323, combine the 6 fields to obtain the MAC address of the device.

Among them, step 1323 includes: using the type value representing the device as the first two fields of the MAC address, wherein the last digit of the first field cannot be 1; The four field values of the address are the same, and the MAC address of the device is obtained.

Take the current MAC address as an example, the MAC address is 48 bits, divided into six fields, each field is a byte, 8 bits, expressed in hexadecimal, for the 6 fields of the MAC address, the first two fields In the conversion algorithm, it indicates the type value of this device. The range requirement is that the last digit of the 8-bit value in the first field cannot be 1, so as to exclude that this MAC is generated as a multicast MAC address. The value of each field in the last four fields and The values of the four fields of the IP address are consistent.

It needs to be explained here that the present invention does not limit the algorithm for obtaining the IP address and the MAC address by converting the location information parameter as an input parameter, as long as the IP address and the MAC address value in the network system can be obtained through this algorithm, it is all within the scope of the present invention. listed.

The value of the set position information parameter is unique in the network system of the device, and the IP address obtained through conversion as an input parameter is also unique in the network system of the device, and will not conflict with the IP addresses of other devices in the network system. Similarly, the MAC address will not conflict with the MAC addresses of other devices in the network system.

In the above-mentioned embodiments of the present invention, in the process of converting IP address and MAC address, for example, the location information parameters obtained by each device through location information mapping are X, Y, Z, network number, and device number, using F1, F2, F3 and F4 represent the four conversion algorithms of the IP four-segment address. The IP address obtained through the conversion algorithm is F1(X,Y).F2(Z).F3(network number).F4(device number), each field It is in decimal, and its subnet mask is used to distinguish different networks, that is, the four fields corresponding to IP are 255.255.255.0; the MAC address of each device is obtained as 00:01:F1(X,Y):F2(Z): F3 (network number): F4 (device number), each field is hexadecimal.
