Detailed Description
The drawings are only for purposes of illustration and are not to be construed as limiting the invention. For a better understanding of the following embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
Example 1
The embodiment provides a method for configuring an IP address and detecting a conflict for a distributed device, which is applied to a server in the distributed device, and is used for automatically acquiring an available IP address by using an arping command, and recording each allocated IP address and a corresponding MAC address (media access control address) in a mapping relation table manner, so that after the IP address allocation is completed, the IP address conflict situation can be quickly checked by using the mapping table and the arping command, and the overall method is low in implementation difficulty and low in cost.
In the method, the distributed equipment refers to a spliced wall display system and consists of a plurality of boxes. The execution main body of the method, namely the server in the distributed equipment, refers to one of the master server boxes in the distributed equipment for managing the rest boxes. The remaining boxes are referred to in the present method as clients of the distributed device.
As shown in fig. 1, the method includes:
s110: acquiring an available IP address in a first network segment;
in this step, the server needs to set an IP address of a certain network segment first, and uses the IP address as a first network segment, and obtains an available IP address in the first network segment. The specific means of obtaining is preferably to obtain through an arping command, where the arping command is to test a network through a ping command check, where the command is based on an ARP broadcast mechanism, and checks whether a certain IP Address is already used in a network segment through broadcast, and in the broadcast process, if a reply is received, it indicates that the IP Address is already occupied, and the content of the reply is a MAC Address of the IP Address, and if no reply is received, it indicates that the IP Address is not already occupied.
S120: when the MAC address of a client in the distributed equipment is received, allocating one available IP address for the client;
in this step, it is necessary to wait for the client in the distributed device to actively send out a custom protocol data packet at least including its MAC address, where the header of the data packet may be custom. That is, the allocation of the IP address needs to be initiated by the client of the distributed device actively, or optionally, the server sends a request to each client first, requesting that the server send at least its MAC address to the server, so that the server allocates the IP address. The need to assign an IP address based on the MAC address sent by the client is for logging in subsequent steps.
In a preferred embodiment, when allocating an available IP address to the client, the following steps are performed only after receiving the allocation confirmation information of the client, and based on this, the specific implementation procedure of step S120 is: when the MAC address of the client in the distributed equipment is received, one available IP address is distributed to the client, and the MAC address corresponding to the distributed IP address is sent to the client.
In this step, after receiving the IP address allocated by the server and the MAC address corresponding to the allocated IP address, the client matches the corresponding MAC address with its own MAC address, and sends an allocation confirmation message to the server after confirming the matching, so as to ensure that the allocated IP address is corresponding to its own MAC address. The server side confirms that the allocated IP address is successfully allocated to the client side after receiving the allocation confirmation information of the client side, and if the allocation confirmation information is not received for a period of time, the server side can select to reallocate the IP address for the client side.
S130: mapping the allocated IP address and the MAC address of the client to obtain a mapping relation table;
in this step, the server records the allocated IP addresses and the MAC addresses of the clients to which the IP addresses are allocated, using the mapping relationship table, so as to be used as a basis for detecting whether IP addresses conflict or not in the following process, thereby more conveniently and quickly detecting whether the allocated IP addresses conflict or not.
S140: sending MAC addresses by all clients which are allocated with IP addresses in a first network segment through a broadcast request;
in this step, the server requests all clients to which IP addresses have been allocated to send their own MAC addresses in a broadcast manner, so as to check whether the MAC addresses fed back by the clients are different from the MAC addresses recorded in the mapping table.
S150: after requesting and receiving the MAC address sent by the client, determining the IP address conflict condition of the client by using an arping command according to the IP address of the client, the received MAC address of the client and the mapping relation table.
In this step, since one MAC address mapped in correspondence with the IP address of the client is already recorded in the mapping relationship table, it can be already determined whether the MAC address fed back by the client is different from the MAC address correspondingly recorded in the mapping relationship table according to the IP address of the client, the received MAC address of the client, and the mapping relationship table, and then, it is further determined according to the arping command that if the IP addresses are in conflict, the MAC address corresponding to the conflicting IP address is used to determine whether there are multiple clients with IP address conflict.
Preferably, this step should be executed again at regular intervals to ensure that the conflict situation of the IP addresses of the clients is repeatedly detected and confirmed all the time.
As shown in fig. 2, the specific implementation procedure of step S150 is as follows:
s151: determining a first MAC address according to the IP address of the client and the mapping relation table;
in this step, the first MAC address is a MAC address corresponding to the IP address of the client in the mapping table.
S152: judging whether the received MAC address of the client is the same as the first MAC address, if so, executing step S153; if not, executing step S154;
s153: determining that the IP address conflict condition of the client is that no IP address conflict occurs;
because the MAC address fed back by the client is requested to be the same as the corresponding MAC address in the mapping relation table, i.e. the first MAC address, it indicates that the IP address of the client corresponds to only one MAC address, and the MAC address is the MAC address of the client itself, and there is no conflict in the allocation of the IP addresses.
S154: determining whether the IP address conflict situation of the client is the occurrence of IP address conflict by using an arping command;
because the MAC address requested to be fed back by the client is different from the corresponding MAC address in the mapping relationship table, that is, the first MAC address, it indicates that the IP address of the client may correspond to more than two MAC addresses, and that more than two clients may use the same IP address at the same time, and the allocation of the IP address may conflict. Therefore, the MAC address corresponding to the IP address of the client can be determined by using an arping command to determine whether the allocation of the IP address conflicts.
As shown in fig. 3, the specific implementation procedure of step S154 is:
s1541: executing an arping command on the IP address of the client to obtain a second MAC address;
s1542: judging whether the received MAC address of the client is the same as the second MAC address, if so, executing step S1543; if not, go to step S1544;
s1543: determining that the IP address conflict condition of the client side does not occur;
in this step, after the second MAC address is obtained by performing an arping command on the IP address of the client, if the received MAC address of the client is the same as the second MAC address, it indicates that there is only one MAC address corresponding to the current IP address, that is, the second MAC address. The reason why the MAC address fed back by the client is different from the first MAC address is that the MAC address of the client itself is changed for some reason, but the allocation of the IP address is not conflicted.
Preferably, in this step, although the IP address conflict condition of the client has been determined that no IP address conflict occurs, since the first MAC address is already different from the corresponding MAC address in the mapping table, it is proved that the MAC address of the client has changed for some reason, the first MAC address in the mapping table should be replaced with the second MAC address, so as to avoid performing a redundant step to determine that no IP address conflict occurs when the IP address of the client is detected again.
S1544: determining that the IP address conflict condition of the client is the occurrence of IP address conflict;
in this step, after the second MAC address is obtained by executing an arping command on the IP address of the client, if the received MAC address of the client is different from the second MAC address, it indicates that there are actually at least two MAC addresses corresponding to the current IP address, and the reason why the MAC address fed back by the client is different from the first MAC address is that the allocation of the IP address conflicts.
Preferably, in this step, since it is determined that the IP address of the client has collided, the collision should be recorded, and therefore, the IP address of the client and the received MAC address of the client should be recorded to mark the collision.
The method for configuring the IP address and detecting the conflict for the distributed device provided by this embodiment is applied to a server in the distributed device, and acquires an available IP address in a certain network segment based on an arping command, allocates an IP address after receiving an MAC address sent by each client, and performs mapping of two addresses of the same client to obtain a mapping relation table, which is used as an important basis for subsequent IP address collision detection, and during a collision checking process, determines a collision condition of the IP address of each client by using a broadcast technology and the arping command. The method has low execution cost, can realize high-efficiency IP address allocation and conflict detection, and improves the installation and configuration efficiency of each client.
Example 2
Based on the same concept as that of the previous embodiment, this embodiment provides a method for configuring an IP address and detecting a conflict for a distributed device, which is applied to a client in the distributed device, where the client refers to a box in the distributed device.
As shown in fig. 4, the method includes:
s210: sending the MAC address of a client to a server in the distributed equipment, and receiving an IP address distributed by the server;
in this step, the client actively sends a custom protocol data packet at least containing its MAC address to the server, and the header of the data packet may be custom. Optionally, the client may send its MAC address to the server after receiving the MAC address sending request of the server.
After receiving the MAC address of the client, the server allocates one of the available IP addresses to the client, maps the allocated IP address and the MAC address of the client to obtain a mapping relation table, and meanwhile, the client receives the IP address allocated by the pride server.
In a preferred embodiment, as shown in fig. 5, the specific implementation procedure of step S210 is as follows:
s211: sending the MAC address of the client to a server in the distributed equipment;
s212: receiving an IP address distributed by a server and an MAC address corresponding to the distributed IP address sent by the server;
s213: judging whether the MAC address corresponding to the allocated IP address is the same as the MAC address of the client, if so, executing step S214; if not, go to step S215;
in this step, after acquiring the allocated IP address, the client further determines whether the MAC address corresponding to the IP address matches its own MAC address.
S214: sending confirmation distribution information to a server;
if the MAC address corresponding to the IP address matches the MAC address of the server, it can be determined that the allocated IP address is the IP address of the server, and the server maps the allocated IP address with the MAC address of the client after receiving the allocation confirmation information, so as to obtain a mapping table.
S215: no response is made or error distribution information is sent to the server;
if the MAC address corresponding to the IP address does not match the MAC address of the client, it indicates that the allocated IP address cannot be used as the IP address of the client, and the client may not respond any more, wait for the server to resend the newly allocated IP address, or may feed back an incorrect allocation message to the server, and notify the server that an IP address needs to be reallocated.
S220: and after receiving a request for sending the MAC address through broadcasting, sending the MAC address of the client to the server.
In this step, the server may request all the clients to send their own MAC addresses through broadcasting, and then the server may execute this step after receiving the request, that is, send the current MAC address to the server, so that the server may determine the IP address conflict condition of the client according to the IP address of the client, the received MAC address of the client, and the mapping relationship table, and by using an arping command after requesting and receiving the MAC address of the client.
Therefore, the step is that the server actively detects and confirms the IP address conflict condition of the client.
In a preferred embodiment, the client may also actively detect and confirm the IP address conflict condition of the client, so that the method may further perform the following steps while performing step S220 when the condition is satisfied after performing step S215:
s230: and determining the IP address conflict condition of the client by using the arping command.
The step is that the client terminal actively initiates the detection and confirmation of the conflict condition of the IP address of the client terminal, preferably, the step should be executed again at a certain time interval so as to ensure that the conflict condition of the IP address of the client terminal is repeatedly detected and confirmed all the time.
The specific execution process of step S230 is:
s231: determining the IP address conflict condition of the client by using an arping command;
s232: judging whether a reply of an arping command is received, if so, executing step S233; if not, go to step S234;
and based on the arping command, whether a certain IP address is used on the network segment is checked through broadcasting, if a reply is received in the broadcasting process, the IP address is occupied, the reply content is the MAC address of the IP address, and if no reply is received, the IP address is not occupied.
S233: determining that the IP address conflict condition of the client is the occurrence of IP address conflict;
s234: determining that the IP address conflict condition of the client side does not occur;
the difference between this embodiment and embodiment 1 is that the execution main body of this embodiment is a client in a distributed device, but both are based on the same inventive concept, and therefore, in this embodiment, the same definitions as those mentioned in the foregoing two embodiments, the principle of the same step executed by the same execution main body, and the beneficial effects thereof may refer to the description in embodiment 1, and are not repeated herein.
