Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.
Fig. 2 is a schematic flowchart of a method for updating a configuration file according to an embodiment of the present application, where the method is applied to an OLT interface board of an optical line terminal, and includes:
s201: and acquiring the configuration file version identification before the OLT interface board is restarted.
Specifically, the OLT interface board may be restarted for various reasons, and after being restarted, in order to ensure that the ONU in communication connection with the OLT interface board normally communicates, it is necessary to ensure that the configuration files of all ONUs are the configuration files of the latest version. In some practical applications, although the OLT interface board is restarted, the ONU is not restarted, and the ONU usually caches the configuration file, so that the configuration file is currently stored in the ONU in this case, but the configuration file locally stored in the ONU may be the latest version of the configuration file or may not be the latest version of the configuration file. The configuration file of the latest version may be understood as the configuration file before the restart of the OLT interface board.
In an optional implementation manner of the present application, the OLT interface board is usually in communication connection with the main control board, and the main control board generally stores configuration information of the ONU in communication with the OLT interface board, so that after the OLT interface board is restarted, the configuration file before the OLT interface board is restarted can be obtained from the main control board through the inter-board communication mechanism.
S202: and sending an update notification message through each OLT interface of the OLT interface board.
Wherein, the update notification message at least comprises the version identification of the acquired configuration file.
In a specific implementation manner of the present application, after the OLT interface board sends an update notification message to the ONU communicatively connected to each OLT interface board through each OLT interface, the ONU may update the configuration file according to the locally stored configuration file, and specifically, after the ONU receives the update notification message, if it is determined that the version identifier of the configuration file obtained in the notification message is consistent with the version identifier of the locally stored configuration file, the configuration file may be updated according to the locally stored configuration file.
In another specific implementation manner of the present application, the update notification message may further carry a configuration self-update identifier, where the configuration self-update identifier is used to notify the ONU to update the configuration file according to the locally stored configuration file. In view of the above, after the OLT interface board sends the update notification message to the ONUs communicatively connected to the OLT interface boards through the OLT interfaces, when the ONUs update the configuration files according to the locally stored configuration files, if the ONUs can analyze the configuration self-update identifier from the received update notification message, it may check whether the version identifier of the locally stored configuration file is consistent with the acquired version identifier of the configuration file, if so, it indicates that the locally stored configuration file is the configuration file before the OLT interface board is restarted, and the configuration file may be updated by using the locally stored configuration file.
In view of the above, in a specific implementation manner of the present application, the update notification message may be sent to the ONU along with the discovery authorization message broadcast by the OLT interface board, because once the OLT interface board is restarted, each ONU communicatively connected to the OLT interface board needs to register again.
As will be understood by those skilled in the art, for an OLT interface board, it generally has a plurality of OLT interfaces, and one OLT interface may be in communication connection with a plurality of ONUs, and among these ONUs, there may be an ONU with an available locally stored configuration file and an ONU with an unavailable locally stored configuration file, and for the two types of ONUs, the OLT may give two different processing manners, i.e., S203 and S204, described below.
S203: and receiving an update confirmation message, and confirming that the ONU connected with the OLT interface receiving the update confirmation message has updated the configuration file.
Wherein, the update confirmation message may include: the configuration update success flag may, of course, further include: the ONU side configures information such as the version id of the file, which is not limited in the present application.
Specifically, after the OLT interface board broadcasts the discovery authorization message, the ONU sends a registration request message to the OLT interface board according to the discovery authorization message to complete ONU registration.
S204: and receiving the update request message, and sending a version update message through the OLT interface receiving the update request message.
The version updating message carries the configuration file corresponding to the acquired configuration file version identification.
And if the OLT receives the update request message, it may indicate that the configuration file locally stored on the ONU side is unavailable, and in order to ensure that the configuration file on the ONU side is successfully updated, the OLT needs to send the configuration file corresponding to the acquired configuration file version identifier to the ONU, so that the ONU successfully updates the configuration file.
The update request message may include: configuring the update failure flag may, of course, further include: the ONU side configures information such as the version id of the file, which is not limited in the present application.
In a preferred implementation manner of the present application, after receiving the update request message, the OLT may analyze a configuration update failure identifier from the update request message and send a version update message through an OLT interface that receives the update request message when determining that the version identifier of the ONU-side configuration file is inconsistent with the acquired configuration file version identifier.
Of course, the version update message may also be sent through the OLT interface that receives the update request message only when the configuration update failure flag is resolved, or only when it is determined that the version flag of the ONU-side configuration file is inconsistent with the acquired configuration file version flag.
In a specific implementation manner of the present application, similar to the update confirmation message, the update request message may also be sent to the OLT interface board along with the registration request message.
In a specific implementation manner of the present application, the update request message at least includes a configuration file version identifier of the OUN; before sending the version update message through the OLT interface that received the update request message, the OUN configuration file version identifier may also be compared with the acquired configuration file version identifier, and if not, the version update message is sent through the OLT interface that received the update request message.
In another specific implementation manner of the present application, the method for updating a configuration file may further include:
acquiring an updated configuration file version identifier;
sending configuration file notification messages through each OLT interface of an OLT interface board; wherein the profile advertisement message comprises at least an updated profile version identification.
As can be seen from the above, in the solution provided in this embodiment, after the OLT interface board obtains the version identifier of the configuration file before the OLT interface board restarts, an update notification message is sent through each OLT interface of the OLT interface board, and by receiving an update confirmation message, it is confirmed that the ONU connected to the OLT interface that receives the update confirmation message has updated the configuration file, and by receiving an update request message, the OLT interface that receives the update request message sends a version update message. It can be seen that in the scheme provided in this embodiment of the application, the OLT sends the update request message to the ONU only when receiving the update request message, so that the ONU updates the configuration file according to the configuration file sent by the OLT, and therefore, when updating the configuration file on the ONU side, the amount of interactive data is greatly reduced, the efficiency of updating the configuration file on the ONU side is improved, and thus, the interruption time of the normal service of the ONU can be shortened, and the user experience is improved.
Fig. 3 is a schematic flowchart of another configuration file updating method provided in an embodiment of the present application, where the method is applied to an optical network unit ONU, and includes:
s301: an update notification message is received.
The update notification message at least includes a configuration file version identifier, and certainly, the configuration file update message may also carry information such as a configuration self-update identifier, which is not limited in this application.
The configuration file version identifier included in the update notification message may be: and identifying the version of the configuration file before the OLT is restarted after the OLT is restarted.
The configuration self-updating identifier is used for informing the ONU to update the configuration file according to the locally stored configuration file.
In a specific implementation manner of the present application, the update notification message may be sent to the ONU along with a discovery authorization message broadcast by an OLT interface board.
S302: and comparing the configuration file version identification with the locally stored ONU configuration file version identification.
In a specific implementation manner of the present application, when the update notification message carries the configuration self-update identifier, this step may be performed after the ONU analyzes the configuration self-update identifier from the update notification message.
S303: and confirming that the configuration file version identification is inconsistent with the locally stored ONU configuration file version identification, and sending an updating request message.
When the ONU determines that the configuration file version identifier is not consistent with the locally stored ONU configuration file version identifier, the ONU locally stored configuration file may be considered to be unavailable, that is, the ONU fails to update the configuration file by using the locally stored configuration file.
The update request message carries locally stored ONU configuration file version identifiers, and certainly, the update request message may also carry configuration update failure identifiers and other information, which is not limited in the present application.
In a specific implementation manner of the present application, the update request message may be sent to the OLT interface board along with the registration request message.
S304: a version update message is received.
And the version updating message carries the configuration file corresponding to the configuration file version identification.
And after receiving the version updating message, the ONU can analyze the configuration file corresponding to the configuration file version identifier and update the configuration file through the analyzed configuration file.
In a preferred implementation manner of the present application, when the ONU determines that the version identifier of the configuration file is consistent with the version identifier of the locally stored ONU configuration file, the ONU sends an update confirmation message, so that the OLT can be notified that the locally stored configuration file of the ONU is an available configuration file, and the OLT does not need to send the configuration file.
Specifically, the update confirmation message may include: the configuration update success flag may, of course, further include: the ONU side configures information such as the version id of the file, which is not limited in the present application.
In addition, similar to the update request message described above, an update confirmation message may also be sent to the OLT interface board along with the registration request message.
In an optional implementation manner of the present application, the method for updating a configuration file may further include:
receiving a configuration file notification message; wherein the profile advertisement message comprises at least an updated profile version identification;
and replacing the locally stored ONU configuration file version identification according to the updated configuration file version identification.
As can be seen from the above, in the scheme provided in this embodiment, after receiving the update notification message, the ONU compares the version identifier of the configuration file with the version identifier of the locally stored ONU configuration file, and sends the update request message only when the two version identifiers are inconsistent, and receives the version update message, so that when updating the configuration file on the ONU side, the amount of interactive data is greatly reduced, the efficiency of updating the configuration file on the ONU side is improved, the interruption time of the normal service of the ONU can be further shortened, and the user experience is improved.
The configuration file updating method provided by the embodiments shown in fig. 2 and fig. 3 is comprehensively described below with reference to the ONU registration process.
Referring to fig. 4, a signaling flow diagram of a configuration file updating method is provided.
After an OLT interface board is restarted, each ONU in communication connection with each OLT interface of the OLT interface board needs to register again, and the specific process is as follows:
firstly, after the OLT interface board is restarted, a discovery authorization message carrying a self-updating identification and a latest configuration version identification is generated (S401), and broadcasts the discovery authorization message (S402), after the ONU receives the discovery authorization message, parsing the message, performing configuration file self-update according to the self-update identification and the latest configuration version identification contained in the message (S403), then a registration request message is generated according to the configuration file updating result and the configuration version identification of the local ONU configuration file (S404), and sends the registration request message to the OLT interface board (S405), after the OLT interface board receives the registration request message, judging whether the ONU successfully self-updates the configuration file according to the configuration file updating result carried in the ONU and the configuration version identification at the ONU side (S406), if the ONU successfully self-updates, the OLT interface board completes the subsequent ONU registration according to the prior art (S409); if the self-updating is not successful, the configuration file corresponding to the latest configuration version identifier is sent to the ONU side (S407), the ONU updates the configuration file after receiving the configuration file (S408), and then the ONU registration is completed according to the prior art (S409).
The latest configuration version identification can be understood as follows: and the version identification of the configuration file before the OLT is restarted is obtained after the OLT is restarted.
The configuration file update result may be that the configuration file is successfully updated, and at this time, the result includes a configuration update success identifier, and at this time, it may be understood that an update confirmation message is carried in the registration request, and the OLT may confirm that the ONU has updated the configuration file according to the message carried in the registration request.
The configuration file update result may also be a configuration file update failure, where the result includes a configuration update failure identifier, and at this time, it may be understood that an update request message is carried in the registration request, and the OLT may send a version update message to the ONU according to the message carried in the registration request.
Specifically, whether the discovery authorization message or the registration request message is transmitted according to a format specified by the relevant specification.
It can be understood by those skilled in the art that values of each identification bit in a corresponding protocol are specified in a common specification, but in the process of making the specification, some bits are reserved in consideration of factors such as convenience for later expansion, and the like, and when a receiving end analyzes message data after receiving the message data, values of the reserved bits can be ignored, that is, according to the specification, the values of the reserved bits do not affect the analysis result of the message.
In view of the above, when the self-updating flag and the latest configuration version flag are set in the discovery authorization message, the reserved bits specified in the specification may be considered, and the information is represented by the reserved bits, but in this case, unlike the prior art, when the ONU receives the discovery authorization message and then parses the message, the ONU does not completely ignore the value of the reserved bits, but needs to parse the self-updating flag and the latest configuration version flag from the reserved bits according to the convention.
In a preferred implementation manner of the present application, the self-updating flag may be located in a discovery message domain of an MPCP (Multipoint Control Protocol) discovery authorization message, where a bit flag of the discovery message domain is a bit of a first preset value, where the bit of the first preset value is a reserved bit;
the latest configuration version identifier may be located in a first preset number of bits of a bit identifier starting from a second preset value in a discovery message domain of the MPCP discovery grant message, where the first preset number of bits is a reserved bit.
Specifically, referring to table 1, information contained in a discovery message domain of an MPCP discovery authorization message is provided.
TABLE 1
The "bit" column in table 1 above can be understood as the position of each identification field in the discovery message field of the MPCP discovery grant message, that is, can be understood as the bit identification of each identification field. As can be seen from the table, the 2 nd to 3 rd bits and the 6 th to 15 th bits are reserved bits, or are called reserved bits, and the self-updating flag and the latest configuration version flag may be located in any one of the reserved bits.
It can be understood that, in general, when the self-updating flag and the latest configuration version flag are represented, consecutive bits are used to facilitate the ONU to perform information analysis, and in addition, the latest configuration version flag requires more bits, so the 2 nd to 3 rd bits can be used to represent the self-updating flag, and the 6 th to 15 th bits can be used to represent the latest configuration version flag.
Preferably, the first predetermined value may be 2, and of course, may also be 3, and so on.
In addition, when a plurality of bits are used to represent the latest configuration version identifier, a value range corresponding to the identifier is relatively large, so preferably, the second preset value may be 6, the first preset number may be 10(15-6+1 is 10), of course, the second preset value may be 7, 8, and the like, and the first preset number may be 9, 8, and the like, which is not limited in this application.
Based on the foregoing description, when the ONU-side configuration version identifier and the configuration update success identifier/configuration update failure identifier are set in the registration request message, these reserved bits specified in the specification may also be considered, and the information is represented by the reserved bits, but in this case, different from the prior art, when the OLT receives the registration request message and then parses the message, the value of the reserved bits is not completely ignored, but the update success identifier/configuration update failure identifier and the ONU-side configuration version identifier need to be parsed from the reserved bits according to an agreement.
In a preferred implementation manner of the present application, the update success flag/configuration update failure flag may be located in a discovery message field of the MPCP registration request message, where a bit flag of the third preset value is a reserved bit;
the ONU-side configuration version identifier may be located in a second preset number of bits of the bit identifier starting from the fourth preset value in the discovery message field of the MPCP registration request message, where the second preset number of bits is reserved bits.
Preferably, the second predetermined number is equal to the first predetermined number.
Specifically, referring to table 2, information contained in the discovery message field of the MPCP registration request message is provided.
TABLE 2
The "bit" column in table 2 above can be understood as the position of each identification field in the discovery message field of the MPCP registration request message, that is, can be understood as the bit identification of each identification field. As can be seen from the table, the 2 nd to 3 rd bits and the 6 th to 15 th bits are reserved bits or are called reserved bits, and the update success identifier/configuration update failure identifier and the ONU-side configuration version identifier may be located in any one of the reserved bits.
It can be understood that, in general, when indicating the ONU-side configuration version identifier and the configuration update success identifier/configuration update failure identifier, continuous bits are used to facilitate the OLT to perform information analysis, and in addition, bits required for the configuration version identifier are more, so that the 2 nd to 3 th bits may be used to indicate the configuration update success identifier/configuration update failure identifier, and the 6 th to 15 th bits may be used to indicate the ONU-side configuration version identifier.
Preferably, the third predetermined value may be 2, and of course, may also be 3, and so on.
In addition, when a plurality of bits are used to represent the ONU-side configuration version identifier, a value range corresponding to the identifier is relatively large, so preferably, the fourth preset value may be 6, the second preset number may be 10(15-6+1 is 10), of course, the fourth preset value may be 7, 8, and the like, and the second preset number may be 9, 8, and the like, which is not limited in this application.
The latest configuration version identification can be understood as follows: and the version identification of the configuration file before the OLT is restarted is obtained after the OLT is restarted.
Corresponding to the configuration file updating method, the embodiment of the application also provides a configuration file updating device.

the second message sending module is specifically configured to receive the update request message, compare the OUN configuration file version identifier with the acquired configuration file version identifier, and send the version update message through the OLT interface that receives the update request message if the OUN configuration file version identifier is not consistent with the acquired configuration file version identifier.
As can be seen from the above, in the solution provided in this embodiment, after the OLT interface board obtains the version identifier of the configuration file before the OLT interface board restarts, an update notification message is sent through each OLT interface of the OLT interface board, and by receiving an update confirmation message, it is confirmed that the ONU connected to the OLT interface that receives the update confirmation message has updated the configuration file, and by receiving an update request message, the OLT interface that receives the update request message sends a version update message.
