Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a method and a device for sending and receiving a repair packet and a fault repair system, which are used for realizing the quick direct connection of fault embedded equipment and a server and further realizing the quick repair of the fault embedded equipment.
First, a method for sending a repair packet according to an embodiment of the present invention is described below, where the method for sending a repair packet is based on a fault repair system.
As shown in fig. 1, the method may include the steps of:
s101: receiving equipment information sent by at least one fault embedded equipment, wherein the equipment information comprises an original IP address of the fault embedded equipment;
it can be understood that, after the embedded device is powered on, the embedded device detects that a failure occurs in itself through a U-Boot (universal Boot loader), and broadcasts device information of itself through the U-Boot at regular or irregular time if the main program is damaged. The server may receive device information broadcast by at least one failed embedded device. Further, the server may present the received device information in a display interface. The U-boot is a single-threaded loop program, which can be used as a boot program of the embedded device. The server may be a TFTP server and may provide repair packets for the failed embedded device.
S102: acquiring a new IP address allocated to each fault embedded device;
it should be noted that the server obtains a new IP address assigned to each failed embedded device, where the new IP address can be reassigned by the user for each failed embedded device. Or the server may reallocate it for each failed embedded device.
S103: sending a modification instruction to each fault embedded device so that each fault embedded device obtains a new IP address for itself from the modification instruction and then directly connects the new IP address with a server, wherein the modification instruction carries the allocated new IP address;
the server can send a modification instruction to each fault embedded device through the prior art, so that each fault embedded device obtains a new IP address for itself from one or more modification instructions through the U-boot, modifies the original IP address of itself into the obtained new IP address for itself through the U-boot, and is directly connected with the server through the new IP address.
S104: receiving repair requests sent by all fault embedded devices;
s105: and sending a repair packet corresponding to the repair request to all the fault embedded equipment so as to complete fault repair of all the fault embedded equipment.
The repair request can carry information such as the device model of the corresponding fault embedded device, so that the server can send a corresponding repair packet to the fault embedded device according to the device model of the fault embedded device.
By applying the embodiment of the invention, the server receives the equipment information which is sent by at least one fault embedded equipment and comprises the original IP address of the fault embedded equipment; acquiring a new IP address allocated to each fault embedded device; sending a modification instruction to each fault embedded device so that each fault embedded device can directly connect with the server by using the new IP address after obtaining the new IP address aiming at the fault embedded device from the modification instruction; receiving repair requests sent by all fault embedded devices; and sending a repair packet corresponding to the repair request to all the fault embedded devices so that all the fault embedded devices complete fault repair. Therefore, the server can allocate new IP addresses to the fault embedded devices in the same network segment and different network segments, so that each fault embedded device can directly connect with the server by using the new IP address after obtaining the new IP address for the fault embedded device from the modification instruction, the IP addresses of the fault embedded devices are not required to be modified one by one manually, the fault embedded devices are quickly and directly connected with the server, and the fault of the fault embedded devices is further quickly repaired.
In addition, the embodiment of the invention can be used for aiming at the fault embedded equipment in the same network segment and also can be used for aiming at the fault embedded equipment in different network segments. By applying the embodiment of the invention, only one server exists in different network segments, so that the embodiment of the invention can be used for providing the repair packet for the fault embedded equipment without deploying the server in each network segment.
In a specific implementation manner, some fault embedded devices are in the same network segment with the server, and can be directly connected with the server, so that the modification of an IP address is not required. In order to save resources of the server, an IP address may be allocated only to a failed embedded device that is on a different network segment from the server. After receiving the device information sent by the at least one failed embedded device, the method for sending the repair packet according to the embodiment of the present invention may further include:
determining all first fault embedded devices from the at least one fault embedded device according to the device information, wherein the first fault embedded devices are fault embedded devices of which the original IP addresses and the server are not in the same network segment;
the obtaining of the new IP address allocated to each failed embedded device includes:
a new IP address assigned to each first failed embedded device is obtained.
The server can determine all first fault embedded devices of which the original IP addresses are not in the same network segment with the server from the at least one fault embedded device according to the original IP addresses of the fault embedded devices carried in the device information and the IP addresses of the first fault embedded devices, and perform subsequent processes. In addition, a user can check the device information sent by at least one failed embedded device on a display interface of the server, and the step of determining all first failed embedded devices which are not in the same network segment with the server can be understood and input to the server after being screened on the interface by the user.
In addition, when the fault embedded device and the server are in the same network segment, the server can be directly connected with the fault embedded device. Subsequently, the server can send the corresponding repair packet to the fault embedded device through the TFTP protocol, so that the fault embedded device completes fault repair through the U-boot. The device information may include information such as a device model of the failed embedded device, so that the server may send a repair packet matching the device model for the failed embedded device.
In one specific implementation, the server does not know the path information sent to each failed embedded device, and sends the modification instruction in a broadcast manner. Since other hosts (including but not limited to non-failing embedded devices) are not present in the network, the modification instructions may be sent in a multicast fashion in order to reduce the processing burden on such hosts. The burden of other hosts outside the multicast group on the network is effectively reduced, and the data sent to the multicast group cannot be transmitted to the drivers of the hosts to be processed, so that the unnecessary waste of resources is avoided. The device information may also carry information on whether the corresponding failed embedded device supports multicast, and before the modification instruction is sent to each failed embedded device, the method for sending the repair packet provided by the embodiment of the present invention may further include:
judging whether the corresponding fault embedded equipment supports multicast or not according to the equipment information;
when the corresponding fault embedded device supports multi-broadcasting, the sending of the modification instruction to each fault embedded device is as follows: multicasting a modification instruction of the corresponding fault embedded equipment;
when the corresponding fault embedded device does not support multi-broadcast, the sending of the modification instruction to each fault embedded device is as follows: and broadcasting the modification instruction of the corresponding fault embedded equipment.
For example, when the failed embedded device includes A, B, C, D and E five devices, wherein, according to the device information, it can be known that A, B and C support multicast and D and E do not support multicast. Respectively multicasting a modification instruction for A, a modification instruction for B and a modification instruction for C; the modification instruction for D and the modification instruction for E are broadcast separately. For A, B and C, it will receive the modification instruction for a, the modification instruction for B, the modification instruction for C, the modification instruction for D, and the modification instruction for E, and select the modification instruction carrying the new IP address for itself. For D and E, it only receives the modification instruction for D and the modification instruction for E, and selects the modification instruction carrying the new IP address for itself.
In a specific implementation manner, the device information may further include a MAC address of the failed embedded device;
the sending of the modification instruction to each faulty embedded device includes:
respectively sending modification instructions carrying the MAC address of each fault embedded device and the new IP address correspondingly distributed to each fault embedded device;
the new IP address for itself is: a new IP address for its own MAC address.
In order to better ensure that the server allocates a new IP address for each failed embedded device, ensure that each failed embedded device determines a new IP address for itself, and avoid occupying IP addresses of other embedded devices, the device information may further include an MAC address of the failed embedded device. And the sent modification instruction carries the MAC address of each fault embedded device and the corresponding allocated new IP address, so that each fault embedded device can screen out the new IP address aiming at the MAC address of the fault embedded device through the U-boot.
Of course, it can be understood that the device information may also carry other information that can uniquely identify the faulty embedded device, and the embodiment of the present invention does not limit this type of information.
In a specific implementation manner, the device information may further include a MAC address of the failed embedded device;
before the receiving of the repair requests sent by all the failed embedded devices, the method for sending the repair packet provided by the embodiment of the present invention may further include:
receiving ARP information broadcasted by the at least one fault embedded device;
and storing the corresponding relation between the MAC address of the corresponding fault embedded equipment carried in the ARP information and the new IP address.
It can be understood that after the failed embedded device modifies the IP Address, the correspondence between the new IP Address and the MAC Address of the failed embedded device is not stored in other hosts in the network (including but not limited to the server and each switch device), for example, the correspondence between the new IP Address and the MAC Address of the failed embedded device is not stored in an Address Resolution Protocol (ARP) table, and the U-boot cannot respond to the ARP requests of the other hosts. In order to avoid that subsequent fault embedded equipment cannot perform information interaction with other hosts, after the fault embedded equipment modifies the IP address of the fault embedded equipment, ARP information can be actively broadcasted through the U-boot, so that the other hosts can increase and store the corresponding relation between the new IP address and the MAC address of the fault embedded equipment. After the server stores the corresponding relationship, the server can send the corresponding repair packet to the fault embedded device, so that the fault embedded device can complete fault repair.
On the other hand, an embodiment of the present invention provides a method for receiving a repair packet, where the method for receiving a repair packet is based on a fault repair system, and as shown in fig. 2, the method may include the following steps:
s201: sending equipment information to a server, wherein the equipment information comprises an original IP address of the fault embedded equipment;
after the embedded device is powered on, the U-boot detects that the embedded device has a fault, if the main program is damaged, the embedded device broadcasts own device information at regular time or irregular time.
S202: receiving a modification instruction sent by the server, wherein the modification instruction carries the allocated new IP address, and the new IP address is an address allocated by the server;
the modification instructions are sent by the server for each failed embedded device. When a plurality of fault embedded devices are available, the fault embedded devices receive the modification instructions through the U-boot, then screen out the modification instructions for the fault embedded devices through the U-boot, and the modification instructions for the fault embedded devices carry the new IP addresses distributed by the server and for the fault embedded devices.
S203: modifying the original IP address of the fault embedded equipment into a corresponding new IP address so as to directly connect the server by using the new IP address;
and the fault embedded equipment modifies the original IP address into a corresponding new IP address through the U-boot and is directly connected with the server through the new IP address.
S204: sending a repair request to the server;
s205: and receiving a repair packet which is sent by the server and corresponds to the repair request, and completing fault repair.
And the fault embedded equipment sends a repair request to the server through the U-boot, and receives a repair packet which is sent by the server and corresponds to the repair request through the U-boot to complete fault repair.
By applying the embodiment of the invention, after the embedded equipment fails, the IP address is modified, the modified new IP address is directly connected with the server, the repair request is sent to the server, and the repair packet which is sent by the server and corresponds to the repair request is received to complete fault repair. The quick direct connection between the fault embedded equipment and the server is realized, and the quick repair of the fault embedded equipment is further realized.
In a specific implementation manner, in order to better ensure that the server allocates a new IP address for each failed embedded device, it is ensured that each failed embedded device determines a new IP address for itself, and the IP addresses of other embedded devices are prevented from being occupied. The modification instruction also carries the MAC address of the fault embedded equipment;
the modifying the original IP address of the fault embedded device to the corresponding new IP address comprises:
and modifying the original IP address of the fault embedded equipment into a new IP address corresponding to the MAC address of the fault embedded equipment.
In a specific implementation manner, the modification instruction also carries an MAC address of the faulty embedded device;
before sending the repair request to the server, the method for receiving the repair packet according to the embodiment of the present invention may further include:
and broadcasting ARP information carrying the corresponding relation between the MAC address of the fault embedded equipment and the new IP address so that the server stores the corresponding relation between the MAC address of the fault embedded equipment and the new IP address after receiving the ARP information.
It can be understood that, after determining a new IP address for its own MAC address from the modification instruction through the U-boot, the failed embedded device modifies the original IP address to the new IP address through the U-boot, and actively broadcasts the ARP information, so that other hosts including the server receive the ARP information and then store the corresponding relationship between the MAC address of the failed embedded device and the new IP address, so that the failed embedded device can perform subsequent information interaction with other hosts. The server can send the repair packet corresponding to the fault embedded device according to the corresponding relation, so that the fault embedded device completes fault repair. The device information broadcast by the fault embedded device can also carry information such as a device model, so that the server sends a corresponding repair packet to the fault embedded device according to the device model.
Specifically, as shown in fig. 3, it is a schematic diagram of interaction between a server and a failed embedded device:
if the fault embedded equipment has faults, such as the main program is damaged, the equipment information of the fault embedded equipment is broadcasted;
the TFTP server receives equipment information broadcasted by the fault embedded equipment;
the TFTP server can display each received display message and obtain a new IP address allocated to each failed embedded device;
the TFTP server broadcasts or multicasts a modification instruction carrying the obtained new IP address;
each fault embedded device receives a modification instruction, screens out a new IP address for the fault embedded device from the modification instruction through U-boot, and modifies the IP address;
each fault embedded device broadcasts ARP information which carries the corresponding relation between the MAC address of the fault embedded device and the new IP address;
the TFTP server receives ARP information broadcasted by each fault embedded device, stores the corresponding relation between the MAC address of each fault embedded device carried in the ARP information and the new IP address, and is directly connected with each fault embedded device;
after each fault embedded device is directly connected with the TFTP server, a repair request is sent to the TFTP server;
the TFTP server receives repair requests sent by all fault embedded devices; the repair request can carry information such as the equipment model of the corresponding fault embedded equipment;
and the TFTP server sends a corresponding repair packet for each fault embedded device so that each fault embedded device completes fault repair.
After the fault repair of each fault embedded device is completed, the fault repair success information can be fed back to the TFTP server.
