Detailed Description
The drawings are for illustrative purposes only and are not to be construed as limiting the invention. For better illustration of the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the actual product dimensions; it will be appreciated 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 conflict by a distributed device, which is applied to a server side in the distributed device, automatically acquires available IP addresses by using an arping command, and records each allocated IP address and a corresponding MAC address (media access control address) in a mapping relation table mode, wherein after IP address allocation is completed, the IP address conflict condition can be rapidly checked by using the mapping table and the arping command, and the whole 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 subject of the method, namely the server in the distributed equipment, refers to a master control server box in the distributed equipment, which is used 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, take the IP address as a first network segment, and obtain an available IP address in the first network segment. The specific means of acquisition is preferably acquisition by an arping command, in particular an ARP protocol (Address Resolution Protocol ) packet, the network is tested by a ping command check, the command is based on an ARP protocol broadcast mechanism, whether an IP address is already used on a network segment is checked by broadcasting, in the broadcasting process, if a reply is received, the IP address is occupied, and if no reply is received, the content of the reply is the MAC address of the IP address, and if the reply is not received, the IP address is not occupied yet.
S120: when the MAC address of the client in the distributed equipment is received, one available IP address is allocated to the client;
in this step, the client in the distributed device needs to wait to actively send out a custom protocol data packet at least including its MAC address, and the header of the data packet may be custom. That is, the allocation of the IP address needs to be actively initiated by the client of the distributed device, alternatively, the server may first send a request to each client, and request at least send its MAC address to the server, so that the server performs the allocation of the IP address. The need to assign an IP address based on the MAC address sent by the client is for recording in a later step.
In a preferred embodiment, when the available IP address is allocated to the client, the subsequent steps are only performed after receiving the acknowledgement allocation information of the client, based on which the specific implementation procedure of step S120 is: when the MAC address of the client in the distributed equipment is received, one of the available IP addresses is allocated to the client, and the MAC address corresponding to the allocated 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 after confirming the matching, sends confirmation allocation information to the server to ensure that the allocated IP address corresponds to its own MAC address. After receiving the confirmation allocation information of the client, the server confirms that the allocated IP address has been allocated to the client successfully, if the confirmation allocation information is not received for a period of time, the server may choose to reallocate the IP address to the client.
S130: mapping the allocated IP address and the MAC address of the client to obtain a mapping relation table;
in this step, the server uses the mapping relation table to record the allocated IP address and the MAC address of the client corresponding to the allocated IP address, so as to be used as a basic basis for detecting whether the allocated IP addresses collide later, thereby more conveniently and rapidly detecting whether the allocated IP addresses collide.
S140: transmitting the MAC address by broadcasting a client requesting all the allocated IP addresses in the first network segment;
in this step, the server requests all clients with allocated IP addresses 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 relationship table.
S150: after the request and the receiving of the MAC address sent by the client, the IP address conflict condition of the client is determined according to the IP address of the client, the received MAC address of the client and the mapping relation table and by utilizing the arping command.
In this step, since one MAC address mapped corresponding to the IP address of the client is already recorded in the mapping table, it can be determined whether the MAC address fed back by the client is different from the MAC address recorded corresponding to the mapping table according to the IP address of the client, the received MAC address of the client, and the mapping table, and then, according to the arping command, the MAC address corresponding to the conflicting IP address is further determined if the IP address is in conflict, so as to determine whether there are a plurality of clients with the conflicting IP address.
Preferably, this step should be re-executed at regular intervals to ensure that the collision 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 situation of the client is that the IP address conflict does not occur;
since the MAC address fed back by the request client is the same as the corresponding MAC address in the mapping relation table, namely the first MAC address, the IP address of the client only corresponds to one MAC address, and the MAC address is the MAC address of the client, and no conflict occurs in the allocation of the IP address.
S154: determining whether the IP address conflict situation of the client is that IP address conflict occurs or not by utilizing an arping command;
because the MAC address fed back by the requesting client is different from the corresponding MAC address in the mapping relationship table, that is, the first MAC address, the IP address of the requesting client may correspond to more than two MAC addresses, and there may be more than two clients using the same IP address at the same time, the allocation of the IP addresses may collide, or the current MAC address of the client may not coincide with the original mapping for some reasons, and the allocation of the IP addresses may not collide. The MAC address corresponding to the IP address of the client can be determined using the 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 as follows:
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, executing step S1544;
s1543: determining that the IP address conflict situation of the client is that the IP address conflict does not occur;
in this step, after the second MAC address is obtained by executing the 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 means that there is only one MAC address corresponding to the current IP address, that is, the second MAC address. The reason that the MAC address fed back by the client is different from the first MAC address is that the MAC address of the client itself has changed for some reason, but the allocation of the IP address is not conflicting.
Preferably, in this step, although the case of the IP address collision of the client has been determined that no IP address collision has occurred, 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 been changed for some reason, and therefore the first MAC address in the mapping table should be replaced with the second MAC address, so that an unnecessary step needs to be performed to determine that no IP address collision has occurred when the IP address of the client is detected again.
S1544: determining that the IP address conflict situation of the client side is that IP address conflict occurs;
in this step, after the second MAC address is obtained by executing the ping command on the IP address of the client, if the received MAC address of the client is different from the second MAC address, which means that there are at least two MAC addresses corresponding to the current IP address actually, 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 has been determined that the IP address of the client has collided, the collision situation should be recorded, and thus the IP address of the client and the received MAC address of the client should be recorded to mark the collision situation.
The method for configuring the IP address and detecting the conflict of the distributed equipment provided by the embodiment is applied to a server side in the distributed equipment, an arong command is taken as a basis, an available IP address in a certain network segment is obtained, after the MAC address sent by each client side is received, the IP address is distributed, mapping of two addresses of the same client side is made, a mapping relation table is obtained and is used as an important basis for detecting the conflict of the IP address subsequently, and in the process of detecting the conflict, the broadcasting technology and the arong command are utilized to determine the conflict condition of the IP address of each client side. The method has low execution cost, can realize efficient IP address allocation and conflict detection, and improves the installation and configuration efficiency of each client.
Example 2
Based on the same concept as the previous embodiment, the present embodiment provides a method for configuring an IP address and detecting a conflict by 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 the client to a server in the distributed equipment, and receiving the IP address distributed by the server;
in this step, the client actively sends out a custom protocol data packet at least including its MAC address to the server, where the header of the data packet may be custom. Alternatively, the client may send its own MAC address to the server after receiving the MAC address sending request from the server.
After receiving the self 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 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 allocated by a server and an MAC address corresponding to the allocated 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, executing step S215;
in this step, after the client acquires the allocated IP address, it is further confirmed whether the MAC address corresponding to the IP address matches the MAC address of the client.
S214: sending confirmation distribution information to a server;
if the MAC address corresponding to the IP address matches the own MAC address, it can be determined that the allocated IP address is the own IP address, and after receiving the confirmation allocation information, the server maps the allocated IP address with the MAC address of the client to obtain a mapping table.
S215: do not respond at all or send error allocation information to the server;
if the MAC address corresponding to the IP address does not match the own MAC address, which means that the allocated IP address cannot be used as the own IP address, the client may not respond to any response, and the server may resend the newly allocated IP address, or may feedback an error allocation message to the server, to inform the server that an IP address needs to be reassigned.
S220: after receiving a request for transmitting a MAC address through broadcasting, the MAC address of the client is transmitted to the server.
In this step, the server requests all clients to send their own MAC addresses through broadcasting, and then after receiving the request, the server sends the current MAC address to the server, so that after the server requests and receives the MAC address of the client, the server can determine the IP address conflict situation of the client according to the IP address of the client, the received MAC address of the client and the mapping table, and by using the arping command.
Therefore, the step is that the server side actively detects and confirms the IP address conflict condition of the client side.
In a preferred embodiment, the client may also actively detect and confirm the collision of its own IP address, so the method may perform the following steps while satisfying the condition to perform step S220 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 actively initiates the detection and confirmation of the conflict situation of the IP address of the client, and preferably, the step should be executed again at regular intervals so as to ensure that the conflict situation of the IP address of the client is repeatedly detected and confirmed all the time.
The specific implementation procedure of step S230 is as follows:
s231: determining the IP address conflict condition of the client by utilizing an arping command;
s232: judging whether a reply of an arping command is received, if yes, executing step S233; if not, go to step S234;
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 content of the reply is the MAC address of the IP address, and if no reply is received, the IP address is unoccupied.
S233: determining that the IP address conflict situation of the client side is that IP address conflict occurs;
s234: determining that the IP address conflict situation of the client is that the IP address conflict does not occur;
the difference between the present embodiment and embodiment 1 is that the execution body of the present embodiment is a client in the distributed device, but both are based on the same inventive concept, so in the present embodiment, the same definition as mentioned in the foregoing two embodiments, the principle of the same steps executed by the same execution body and the beneficial effects thereof can be referred to the description in embodiment 1, and will not be repeated herein.
The method for configuring the IP address and detecting the conflict of the distributed equipment is applied to the client side in the distributed equipment, not only can the MAC address be confirmed again when the server side distributes the IP address, but also the IP address of the server side can be circularly detected to be in conflict after the IP address is distributed, and the method is parallel to the confirmation of the conflict condition of the IP addresses of all the client sides by the server side, so that double insurance is formed, and the conflict condition of the IP addresses of the client side can be more timely and accurately checked.
