Detailed Description
In the prior art, when a device requests a router to acquire a static IP address through a DHCP protocol in a networking process, a DHCP server of the router cannot discover the IP address configured to the device, and may have been allocated to other devices through the DHCP protocol, thereby causing a technical problem of network connection failure when the device uses the IP address to perform network connection.
In order to solve the technical problems in the prior art, the application provides a network exception handling method, which includes determining that an exception exists through network connection failure of equipment, inquiring an idle first IP address in a local area network by the equipment, modifying the IP address from a pre-configured second IP address to the first IP address by the equipment, inquiring by the equipment to obtain a physical address corresponding to the second IP address, and determining that the exception is an IP address conflict.
In order to better understand the above technical solutions, exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Example one
Fig. 1 is a flowchart illustrating a network exception handling method according to an embodiment of the present application.
As shown in fig. 1, the network exception handling method is executed by a home appliance side, and specifically includes the following steps:
In the embodiment of the application, in the process of connecting the router, the device requests the router of the local area network to acquire the static IP address through the DHCP protocol so as to connect the server according to the acquired static IP address. Whether the network connection is abnormal is determined by judging whether the network connection is successful when the equipment is connected with the server according to the static IP address.
The static IP address is a fixed IP address which is allocated to the equipment for long term use by using a TCP/IP protocol. An IP address is made up of 4 8 octets separated by dots, for example 192.168.0.1 is an IP address, which is written in dotted decimal format.
It should be noted that the DHCP protocol is a network protocol of a local area network, and works using the UDP protocol, and mainly has the following two purposes: first, an IP address is automatically assigned to an internal network or network service provider; second, users or internal network administrators are given a means to centrally manage all computers.
As a possible situation, when the device requests the router of the local area network to connect to the server through the DHCP protocol, the connection can be successful, and then the device enters a normal working phase.
As another possible case, when the device requests the router of the local area network to connect to the server through the DHCP protocol, the network connection fails, and in this case, it is determined that there is an abnormality in the network connection.
In this embodiment, the static IP address assigned to the device by the router may have been already assigned to other devices by the DHCP protocol for use, but the DHCP protocol of the router cannot discover that the static IP address is already occupied. In this case, when the device uses the static IP address to perform network connection, a network connection failure occurs.
In the embodiment of the application, the device connection fails, and the network connection is abnormal, which may be caused by that the static IP address acquired by the DHCP protocol requesting the router is occupied by other devices, so that the IP address conflicts, and the device networking fails.
In this case, the device obtains the idle first IP Address by querying through an Address Resolution Protocol (ARP) within a network segment range of the lan of the router through a DHCP Protocol.
In the local area network, the IP address and the physical address are in a one-to-one correspondence relationship, and the idle first IP address refers to an IP address not allocated to another device. Since the idle IP address has no corresponding physical address, the IP address of which the physical address is not queried may be used as the idle first IP address.
The second IP address is the above-mentioned static IP address requested by the DHCP protocol to the router, and for convenience of distinguishing, the IP address is defined as the second IP address.
The device network connection failure is caused because the device requests the router to acquire the static IP address through the DHCP protocol and the static IP address can be occupied by other devices. In this case, in order to determine that the device networking failure is caused by IP address conflict, after the device queries an idle first IP address in the local area network, the device modifies the IP address from a pre-configured second IP address to the first IP address.
For example, if the second IP address preconfigured for the device after the DHCP protocol requests the router is 192.168.1.1, after the device fails to request the server for networking through the second IP address, the idle first IP address is 192.168.1.2 in the local area network, and at this time, the device modifies the IP address to 192.168.1.2.
And step 104, the device queries to obtain a physical address corresponding to the second IP address, and determines that the abnormality is IP address conflict.
The physical address, also called a Media Access Control (MAC) address, is an identifier for identifying a lan node.
In the embodiment of the application, the device queries the physical address corresponding to the second IP address through the ARP protocol, and if the physical address corresponding to the second IP address can be successfully obtained through querying, it can be determined that the network connection failure of the device is caused by IP address conflict.
It should be explained that the IP addresses of the devices are in one-to-one correspondence with the physical addresses, and if the physical address corresponding to the second IP address can be successfully queried through the ARP protocol, it is indicated that the second IP address has been allocated to another device for use. Therefore, in this embodiment, the device may determine that the abnormality is an IP address conflict when the network connection fails using the pre-configured second IP address.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages:
according to the network exception handling method, the device determines that an exception exists through network connection failure of the device, the device inquires an idle first IP address in a local area network, the device modifies the IP address from a second IP address configured in advance to the first IP address, the device inquires to obtain a physical address corresponding to the second IP address, and the exception is determined to be an IP address conflict. Therefore, the problem of IP address conflict can be automatically detected when the network connection of the equipment is abnormal, and the technical problem that in the prior art, when the equipment cannot be connected to a server in the network connection process, a user needs to manually search the reason of networking failure, so that a large amount of time is wasted is solved.
In the foregoing embodiment, when the device in step 102 queries the idle first IP address in the local area network, as a possible implementation manner, the device may query a physical address corresponding to each IP address in a network segment of the local area network, and further determine whether each IP address in the network segment of the local area network has a corresponding physical address, so as to use an IP address where no physical address is queried as the idle first IP address. The specific implementation process is shown in the second embodiment.
Example two
Fig. 2 is a schematic flowchart of a network exception handling method according to a second embodiment of the present application.
As shown in fig. 2, the method specifically includes the following steps:
In the embodiment of the application, when the device requests the router for the acquired static IP address to connect the server through the DHCP protocol, after the network connection fails, the physical address corresponding to each IP address can be sequentially inquired in the network segment of the local area network.
After the device is successfully networked according to the network segment IP address of the local area network, a physical address corresponding to the IP address exists. Therefore, whether idle IP addresses exist in the network segments of the local area network can be determined by judging whether the corresponding physical addresses exist in all the IP addresses in the network segments of the local area network.
As a possible situation, after sequentially querying the physical addresses corresponding to the IP addresses in the network segment of the local area network, the device determines that the IP addresses in the network segment all have corresponding physical addresses, and then sequentially executes step 203.
As another possible situation, after sequentially querying the physical addresses corresponding to the IP addresses in the network segment of the local area network, the device determines that the IP addresses in the network segment do not all have corresponding physical addresses. That is, if there is an IP address in the network segment for which no physical address is queried, step 204 is executed.
In the embodiment of the application, if the device determines that each IP address in the network segment has a corresponding physical address, it indicates that no idle first IP address exists in the network segment of the local area network. In this case, the device needs to request the router of the local area network to re-assign the IP address through DHCP, so as to perform network connection according to the re-acquired IP address.
And step 204, taking the IP address of which the physical address is not inquired as an idle first IP address.
In the embodiment of the application, after determining that the IP address of the physical address which is not queried exists in each IP address in the network segment, the device can use the IP address of the physical address which is not queried as the idle first IP address.
As a possible implementation manner, in the process that the device sequentially queries the physical addresses corresponding to the IP addresses in the network segment of the local area network, the first IP address that is not queried as the physical address may be used as the idle first IP address. In this case, the physical addresses of the rest of the IP addresses in the network segment do not need to be queried sequentially, so that the query time is saved to a certain extent.
As another possible implementation manner, in the process that the device sequentially queries the physical addresses corresponding to the IP addresses in the network segment of the local area network, one IP address may be randomly selected from all the IP addresses that are not queried to the physical address, and the selected IP address is used as the idle first IP address.
It should be noted that the implementation process of using the IP address without querying the physical address as the idle first IP address is not limited to the above two implementation manners, and this embodiment is merely an exemplary representation, and specifically, the implementation process is not limited in this embodiment.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages:
in the embodiment of the application, physical addresses corresponding to all IP addresses in a network segment of a local area network are sequentially inquired through equipment, whether all the IP addresses in the network segment have corresponding physical addresses is judged, whether idle first IP addresses exist is determined according to whether all the IP addresses have the corresponding physical addresses, and when the idle first IP addresses do not exist, a router of the local area network is requested to perform IP address allocation again; and when the IP address of which the physical address is not inquired exists, taking the IP address of which the physical address is not inquired as the idle first IP address. The method determines an idle first IP address or requests a router of the local area network to re-distribute the IP addresses by inquiring physical addresses corresponding to all IP addresses in a network segment of the local area network, thereby ensuring that equipment avoids the technical problem of server connection failure caused by IP address conflict in the network connection process.
As a possible situation, after the device network connection fails and the abnormality is determined to be an IP address conflict, the local area network router may be requested to allocate an IP address to the modified physical address through the modified physical address of the device, so as to avoid the problem of IP address conflict. The specific implementation process is shown in the third embodiment.
EXAMPLE III
Fig. 3 is a schematic flowchart of a network exception handling method according to a third embodiment of the present application;
as shown in fig. 3, the specific implementation process of the method includes the following steps:
in step 301, the device requests a router of the local area network to assign a second IP address.
In the embodiment of the application, when the device is connected to a network after being powered on, a second IP address is first requested to be allocated to a router of a local area network through a DHCP protocol.
In the embodiment of the application, after the device acquires the second IP address allocated by the router of the local area network, the IP address of the device is configured as the second IP address, so that the server is connected by using the second IP address.
It should be noted that the second IP address assigned to the device by the router may have been assigned to other devices by the DHCP protocol for use, but the DHCP protocol of the router cannot discover that the second IP address is already occupied. In this case, when the device uses the second IP address to perform network connection, a network connection failure occurs.
In step 304, the device queries the first IP address for idleness within the local area network.
In the embodiment of the present application, the implementation process of step 303 to step 306 may refer to the implementation process of step 101 to step 104 in the above embodiment, and is not described herein again.
In the embodiment of the application, when it is determined that the network connection failure of the device is caused by the IP address conflict of the device, further, the physical address of the device can be modified in a manual operation manner.
In the embodiment of the application, after the device modifies the physical address, the device may request the router of the next local area network to allocate an IP address to the modified physical address through the DHCP protocol. Here, for convenience of distinction, an IP address allocated to the modified physical address may be defined as the third IP address.
In the embodiment of the application, after the device acquires the third IP address corresponding to the modified physical address, the device modifies the own IP address from the first IP address to the third IP address, so that the problem of IP address conflict is avoided.
It should be explained that, because the first IP address is a temporary IP address queried from a network segment of the lan, the IP address of the device needs to be modified to the third IP address, so as to ensure that when the router is connected by using the third IP address corresponding to the modified physical address, no IP address collision occurs.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages:
the network exception handling method of the embodiment includes that a router of a local area network is requested by equipment to allocate a second IP address, the IP address is configured as the second IP address, network connection failure is determined by using the second IP address, an idle first IP address is inquired in the local area network, the IP address is modified from the second IP address configured in advance to the first IP address, a physical address corresponding to the second IP address is obtained by inquiry, IP address conflict is determined as the exception, the equipment modifies the physical address, the router of the local area network is requested to allocate a third IP address to the modified physical address, and the IP address is modified from the first IP address to the third IP address. Therefore, after the fact that the IP address conflicts is determined to be the reason of the failure of the device networking, the physical address of the device is modified, and the IP address of the device is modified into the third IP address corresponding to the modified physical address, so that the technical problem that the device cannot be connected to the server due to the IP address conflicts in the network connection process in the prior art is solved, the IP address conflicts are automatically detected, and the IP address is modified to enable the device to be successfully connected to the server.
