Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
The configuration recovery method provided by the embodiment of the invention can be particularly applied to but not limited to the configuration recovery of the embedded communication equipment. The configuration recovery method provided in this embodiment may be specifically executed by a configuration recovery apparatus, and the configuration recovery apparatus may be integrated in an embedded communication device or separately configured, where the configuration recovery apparatus may be implemented in a software and/or hardware manner. The configuration recovery method and apparatus provided in the present embodiment will be described in detail below.
Fig. 1 is a flowchart illustrating a configuration recovery method according to an embodiment of the present invention, and fig. 2 is a schematic structural diagram illustrating a communication device according to an embodiment of the configuration recovery method. As shown in fig. 1, an execution subject in this embodiment may be a configuration recovery apparatus, and the configuration recovery method provided by the present invention is applied to a communication device including a first storage medium, a second storage medium, and a third storage medium, where the first storage medium and the second storage medium are both nonvolatile memories, and the third storage medium is a volatile memory; the method comprises the following steps:
step 101, after a configuration message for a power failure missing configuration functional element on the communication device is newly acquired, storing the newly acquired configuration message to a third storage medium, and backing up and storing the configuration message in a second storage medium.
As shown in fig. 2, the communication device may be an embedded communication device connected to the network management server through a communication link, and includes a CPU, where the CPU is connected to the first storage medium, the second storage medium, the third storage medium, and the power failure loss configuration functional element, respectively. Of course, the communication device described in the embodiment of the present invention may also be any other device provided with a power loss configuration functional element. For example, the first storage medium and the second storage medium may be different FLASH memory chips, the third storage medium may be a RAM, and the power loss configuration functional element may be a Field-Programmable Gate Array (FPGA).
And step 102, when a configuration storage indication of the power failure loss configuration functional element is triggered, backing up and storing all configuration messages stored in the third storage medium to the first storage medium, and deleting the configuration messages stored in the second storage medium to the first storage medium after the backing up and storing are successful.
When the configuration storage indication of the power loss configuration functional element is triggered, the method may be one of the following two triggering modes:
and the first trigger mode triggers the configuration storage indication of the power failure loss configuration functional element once every set time interval.
And a second trigger mode is that a user manually triggers the configuration storage indication of the power failure loss configuration functional element.
103, according to the configuration messages stored in the first storage medium and the second storage medium, performing configuration recovery on the power failure loss configuration functional element.
If the obtained configuration messages have a sequence, for example, a time sequence of obtaining when the configuration of the communication device is restored, in this embodiment of the present invention, the configuration messages may be stored in the storage media according to the order of obtaining the configuration messages. Typically, if each configuration message is obtained by being issued by a network management server connected to the communication device, the storage sequence of the configuration messages may be the sequence in which the network management server issues the messages. Considering the influence of network environment, the receiving sequence of the configuration message by the communication device is not always consistent with the issuing sequence of the message by the network management server, so the network management server can add a configuration sequence label in each issued configuration message. And storing each configuration message in each storage medium according to the configuration sequence label size on the communication equipment side. Correspondingly, when the communication device has a fault and needs to be configured and restored, the configuration restoration can be performed through the configuration message stored in the first storage medium, and then the configuration restoration can be performed through the configuration message stored in the second storage medium. And when the configuration is recovered, the reading sequence of the configuration messages in each storage medium is a storage sequence. That is, the configuration recovery is performed according to the configuration order of each configuration packet.
In the configuration recovery method provided by this embodiment, by adding a nonvolatile storage medium in a communication device, in a storage interval in which all configuration files stored in a volatile storage medium are stored in an original nonvolatile storage medium, a newly acquired configuration file in the storage interval can be backed up by using the added storage medium, so that before all configuration files in a volatile storage medium are stored in the original nonvolatile storage medium next time successfully, if a failure occurs in the communication device, the configuration of a power failure loss configuration functional element in the device can be recovered based on files in two nonvolatile storage media, thereby solving the problem of successfully deployed configuration loss in a configuration timing storage mechanism in the prior art, and improving reliability and usability of the communication device.
In this embodiment, the configuration recovery operation of the communication device is performed through the configuration packet stored in the first storage medium and the configuration packet stored in the second storage medium, which avoids that the communication device cannot be recovered normally due to the loss of the configuration packet stored in the third storage medium, thereby improving the reliability and usability of the communication device.
On the basis of the above embodiment, the method may further include:
when a configuration storage instruction for the power failure loss configuration functional element is triggered, locking a set file for storing a configuration message in the second storage medium, and creating a new temporary file;
storing the newly acquired configuration message backup for the power failure loss configuration functional element on the communication device in the second storage medium, including:
detecting whether the setting file is locked; if so, storing the newly acquired configuration message for the power failure missing configuration functional element on the communication equipment into the temporary file; otherwise, storing the data in the setting file;
the deleting the configuration packet stored in the second storage medium to the first storage medium after the backup storage is successful includes:
and deleting the locked setting file after the backup storage is successful, and setting the temporary file as the setting file.
Specifically, when a configuration storage indication for a power-down missing configuration functional element on the communication device is triggered, a setting file for storing configuration messages in the second storage medium may be first locked, and then all configuration messages in the third storage medium may be written to the first storage medium. The locking indicates that the configuration message content in the setting file is in an intermediate state written to the first storage medium, and the setting file needs to be deleted if the writing to the first storage medium is successful. If the communication equipment fails before the first storage medium is written, the configuration recovery of the power failure loss configuration functional element needs to be carried out by using the setting file. The user does not perceive the process of writing all the configuration files in the third storage medium into the first storage medium, the user can still normally perform service configuration on the communication equipment in the process, and the configuration files newly acquired in the process are all written into another file, namely a temporary file, in the second storage medium for storing the configuration message.
To more clearly illustrate the technical solutions provided by the embodiments of the present invention, a manner of storing the timing trigger configuration will be described as an example. For example, assume that the period of writing the configuration packet in the third storage medium to the first storage medium (e.g., the main FLASH) at a fixed time is T; at a certain time t1 (set as a first time), N configuration messages (for example, three configuration messages including configuration message 1, configuration message 2, and configuration message 3) are stored in a third storage medium (for example, RAM), the N configuration messages are backed up in the configuration message file 3 in the first storage medium, and a second storage medium (for example, a spare FLASH) is empty;
(1) in a time period from T1 to T1+ T, newly receiving M configuration messages (for example, two configuration messages 4 and 5) sent by a network management server, storing the M configuration messages in an RAM, and if there is no configuration file write operation triggered by a user in the process, synchronously backing up the M configuration messages to a standby FLASH for storing a setting file of the configuration messages;
(2) at a time node T1+ T (set as a second time T2), when the timer expires, an execution operation of writing a file into the primary FLASH is triggered, at this time, a set file for storing a configuration message in the backup FLASH is locked, and all (M + N) configuration messages in the RAM are rewritten into the configuration message file 3 in the primary FLASH in sequence (for example, the sequence of messages issued by the network management server, or the sequence rearranged to ensure the efficiency of configuration recovery); in the process of writing the configuration message file 3, if the webmaster server issues L configuration messages (for example, a configuration message 6), the L configuration messages are newly added to the RAM, and the L configuration messages are stored in a temporary file for storing the configuration messages; after the configuration message file 3 in the main FLASH is successfully written, deleting the original set file in the second storage medium, renaming the temporary file to be the set file, and if no temporary file exists, newly building an empty set file;
(3) after successfully writing the configuration message file 3 in the main FLASH to a certain time point (the time point is less than T1+2T and is set as a third time T3), newly receiving K configuration messages (two configuration messages 7 and 8 are set) sent by the webmaster server, storing (M + N + L + K) messages in the RAM, storing (L + K) messages in the set file in the standby FLASH, and storing (M + N) messages in the configuration message file 3 in the main FLASH; at time t3, after receiving a configuration message instruction triggered by a user, locking the setting file in the second storage medium, and writing all the configuration messages stored in the RAM into the configuration message file 3 in the main FLASH, the network management server does not issue the configuration messages in the process, so that after the configuration message file 3 is successfully written, only the setting file needs to be deleted, and then a blank setting file is newly built in the second storage medium.
For the configuration recovery flow after the communication equipment failure: the configuration recovery of the power failure loss configuration functional element on the equipment can be firstly carried out by adopting a configuration message file 3 in a main FLASH, after the configuration recovery is finished, each configuration message in a setting file in a standby FLASH is read to carry out the configuration recovery of the power failure loss configuration functional element on the equipment, and each configuration message stored in a temporary file in a second storage medium is read to carry out the configuration recovery of the power failure loss configuration functional element on the equipment; further, after the configuration recovery is completed, the original setting file and the temporary file for storing the configuration message in the standby FLASH may be deleted, and an empty setting file is newly created, so that the operation of storing the configuration file into the first storage medium at regular time may be performed subsequently.
The standby FLASH only stores each newly acquired configuration message within a timing interval, and the configuration messages have much smaller capacity than all the configuration messages stored in the RAM, so that the read-write speed of the standby FLASH is higher, the configuration messages can be stored in time, and the power failure loss of the standby FLASH is effectively prevented.
It should be noted that, in the embodiment of the present invention, the manner of storing data in each nonvolatile storage medium is an overwriting manner, that is, the original data in the storage medium is erased first, and then the data is written into the storage medium.
Further, on the basis of the above embodiment, the method may further include:
and receiving each configuration message which is issued by the network management server through the communication link in sequence and is used for configuring the functional elements on the communication equipment in a power failure loss manner.
For example, after obtaining each configuration message to the communication device sequentially issued by the network management server through the communication link, first checking whether a setting file for storing the configuration message in the second storage medium is locked, if not, writing the message into the setting file, and if so, writing the obtained configuration message into a temporary file. Or, the setting file is not locked, and in the process of writing the configuration file into the main FLASH, if the configuration message is newly received, the configuration message is also stored in the setting file of the standby FLASH for storing the configuration message, and the newly received message is marked with a special identifier; and then, after the writing operation to the first storage medium configuration file is completed, reserving the configuration content with the special identifier in the setting file of the configuration message, and deleting the other configuration contents.
Further, on the basis of the foregoing embodiment, after storing the configuration packet in the third storage medium, the method further includes:
analyzing the configuration message, and configuring the power failure loss configuration functional element based on the analysis result;
if the configuration is successful, returning a first notification message that the assembly error code is successful to the network management server, and triggering and executing the operation of the backup storage in the second storage medium; otherwise, deleting the configuration message stored in the third storage medium, and returning a notification message that the assembly error code is failed to the network management server.
