To elaborate on specific embodiments of the present application, the following examples are provided:

fig. 2 is a flowchart of a method for synchronizing a user login status according to an exemplary embodiment of the present application, and as shown in fig. 2, the method, applied to a network management platform, may include the following steps:

step 201, receiving change information sent by an admission device, wherein the change information is related to a user login state.

In one embodiment, the transmitted variation information includes at least one of the following: and the user online information passing through the access equipment, the user offline information passing through the access equipment and the abnormal restarting information of the access equipment.

In an embodiment, the change information may be analyzed to obtain user information included in the change information, and the user obtained through analysis is determined as the user information corresponding to the change information; or, the user registry corresponding to the access device is determined, and then the user information in the user registry is determined based on the user identification information contained in the change information, so that the information amount contained in the change information is reduced, and the generation, transmission and analysis efficiency of the change information is improved.

Step 202, determining the user information corresponding to the change information.

Step 203, in case of completing the synchronous updating of the login status corresponding to the user information based on the change information, sending confirmation information corresponding to the change information to the admission apparatus.

In an embodiment, when the network management platform completes the abnormal restart, the abnormal restart information may be sent to the admission device to obtain the information of the user login state for synchronous update from the admission device, thereby ensuring the synchronization and consistency of the user state information between the network management platform and the admission device after the abnormal restart.

Further, under the condition that the network management platform does not receive the confirmation information sent by the access equipment, the abnormal restarting information is sent again, and the process can be executed repeatedly for a plurality of times; and if the time length of the times of repeatedly executing the process reaches a first preset time length, marking the abnormal restarting information, wherein the marking is eliminated when the network management platform receives the confirmation information.

Further, after a second preset time, the network management platform may determine that, for the abnormal restart information still in the mark processing state, the confirmation information corresponding to the abnormal restart information sent by the access device is not received, and the network management platform may generate an alarm information based on the abnormal restart information to prompt the administrator to perform processing.

Through the embodiment, the access equipment sends the change information related to the user login state to the network management platform, so that the network management platform uniformly maintains the change information related to the user login state and acquired by the access equipment, and a manager can uniformly perform maintenance work such as inquiry, screening and the like on the change information acquired by each access equipment through the network management platform without performing repeated operation on each access equipment, thereby improving the management efficiency of the accessed user information.

In addition, if the network management platform completes the synchronous update of the login state corresponding to the user information based on the change information, the network management platform sends the confirmation information corresponding to the change information to the access equipment, so that the access equipment receives the response information corresponding to the sent change information, determines that the network management platform has received the change information and completes the update based on the change information, and ensures the consistency of the network management platform and the access equipment for the maintained user state information.

Fig. 3 is a flowchart of another method for synchronizing user login statuses according to an exemplary embodiment of the present application, and as shown in fig. 3, the method applied to an admission apparatus may include the following steps:

step 301, sending change information about the user login state to the network management platform, so that the network management platform performs synchronous update based on the change information.

In one embodiment, the variation information may include at least one of: and the user online information passing through the access equipment, the user offline information passing through the access equipment and the abnormal restarting information of the access equipment.

Step 302, re-sending the change information to the network management platform under the condition that the confirmation information sent by the network management platform is determined not to be received.

In an embodiment, if it is determined that the acknowledgement information sent by the network management platform has not been received after the third preset duration, the admission device may perform a marking process on the change information.

Further, after the fourth preset duration, for the change information still in the mark processing state, the admission equipment may determine that the acknowledgement information corresponding to the change information sent by the network management platform is not received.

Further, the admission apparatus may perform a marking process on the change information, such as adding the change information to the transmission failure list, or setting a marking information for the change information; the marking process for the change information can be cancelled when the access device receives the confirmation information sent by the network management platform.

In another embodiment, after receiving the abnormal restart information sent by the network management platform, the admission device may send a confirmation message to the network management platform in response to the abnormal restart information, and send the information of the user login state to the network management platform, so that the network management platform performs synchronous update based on the information of the user login state, thereby ensuring that the user login state information stored in the network management platform after the abnormal restart is completed keeps consistent with the records of the user login state in each admission device connected thereto.

Through the embodiment, the access device can repeatedly send the change information of the confirmation information which is not sent by the network management platform after sending the change information related to the user login state to the network management platform until receiving the confirmation information which is sent by the network management platform aiming at the change information.

For convenience of understanding, the synchronization process of the user login state is described in detail with reference to fig. 4 to 7, where fig. 4 to 7 correspond to four cases that the user login state needs to be synchronized, that is, the admission device receives a trigger event of a user going online, the admission device receives a trigger event of a user going offline, the admission device restarts abnormally, and the network management platform restarts abnormally, and the following describes the synchronization process of the user login state between the admission device and the network management platform in the four cases.

Fig. 4 is an interaction diagram illustrating a method for synchronizing online information of a user according to an exemplary embodiment of the present application, where as shown in fig. 4, the method may include:

step 401, the admission device sends the user online information to the network management platform.

In an embodiment, the admission device may perform access control on a received user online triggering event, and generate online user information for sending to the network management platform after the user online triggering event passes the access control.

In another embodiment, the admission device may periodically traverse the access-controlled user online triggering event, after a period of traversal is finished, determine a newly determined access-controlled user online event in the period, further generate user online information corresponding to all newly determined access-controlled user online events in the period, and send the generated user online information to the network management platform.

For example, in a traversal period, the admission device determines that the received online trigger event a of the user a, the received online trigger event B of the user B, the received online trigger event C of the user C, and the received online trigger event D of the user D pass access control detection, which is different from the above-described embodiment that the user online information corresponding to the online trigger event a is generated immediately after the online trigger event a of the user a passes access control detection, in this embodiment, after a traversal period is ended, the network management device generates the online user information x by combining the determined online trigger event a, the determined online trigger event B, the determined online trigger event C, and the determined online trigger event D in the period, so that the network management device can determine all newly accessed users in the traversal period, that is, the user a, the user B, the user C, and the user D, and then the user login state information maintained by the network management platform is uniformly and synchronously updated at one time, and the user online information does not need to be repeatedly generated for a plurality of online trigger events, so that the operation process of the equipment is simplified, and the information synchronization efficiency of the user login state is improved.

Under the influence of emergencies such as network transmission abnormity, abnormal connection link and the like, in the practical application process, the network management platform can not be ensured to timely and accurately receive user online information sent by each access device, and under the condition that the network management platform can accurately receive the user online information sent by each access device, the network management platform can maintain an online user list maintained by the network management platform according to the received online user information, and the specific step process can refer to the following interaction process I:

step 402a, the network management platform completes synchronous update according to the received user online information.

The network management platform can maintain the user login state information on each access device connected with the network management platform. In an embodiment, the network management platform may establish a list and record user information accessed through each access device in the list, so as to implement the network management platform to synchronously update the user login state of a new user accessed through each access device.

In another embodiment, the maintained user login state information may be stored in segments based on the identification information corresponding to the access device, that is, a mapping relationship, such as a hash mapping relationship, between the identification information of the access device and a storage address of the user login state information is established, and correspondingly, the network management platform stores the user login state information related to the same access device according to the storage address subjected to hash mapping based on the identification information of the access device, or the network management platform may establish an association relationship between the identification information of the access device and the storage address of the user login state information by using the identification information of the access device as a main key and using the user login state accessed through the access device as a value based on a preconfigured key value pair.

The network management platform can preferentially determine the identifier of the access equipment corresponding to the user online information after receiving the user online information sent by the access equipment, and further determine the storage area of the user login state of the received new access user based on the identifier of the access equipment, so that the new online user login state contained in the online user information from the same access equipment is stored in the storage area corresponding to the same identifier information. The network management platform can newly add the user information corresponding to the received online user information in the storage area corresponding to the identifier of the access device, so that the network management platform can synchronize the user login state of the newly accessed user.

Step 403a, the network management platform returns confirmation information to the admission device.

After the network management platform completes the synchronous update, the network management platform sends confirmation information corresponding to the user online information to the access equipment, so that the access equipment receiving the confirmation information determines that the network management platform receives the sent user online information, and completes the update operation of the user login state according to the received user online information.

On the contrary, if the connection between the network management platform and the access device is affected by the abnormal condition and cannot be normally transmitted, the network management platform cannot normally receive the user online information sent by the access device, or the network management platform receives the user online information but cannot normally transmit the confirmation information to the access device, for this, the access device can mark the user online information which is not received by the network management platform within the preset time length and resend the user online information which is still in the mark processing state after another preset time length, and the specific step process can refer to the following interaction process two:

step 402b, the admission equipment marks the sent user online information under the condition that the admission equipment determines that the confirmation information sent by the network management platform is not received after one of the preset time lengths.

The access device may record the time for sending the user online information after sending the user online information, or set a timing corresponding to the user online information, to determine whether the confirmation information corresponding to the sent user online information is received after a preset time period.

In an embodiment, the preset time duration may be a uniform time interval pre-configured by an administrator and applicable to any user online information, or the admission equipment selects a time duration corresponding to a time period in which the time for sending the user online information is located, such as the sending time 11 of the user online information: 30(24 hours) was at 9: 00-14:00, then the corresponding admission device may transmit time slot 9: 00-14: and setting the pre-configured time length corresponding to 00 as the preset time length corresponding to the on-line information of the user.

In another embodiment, the admission device may generate a preset time length corresponding to the user online information in real time according to the sending frequency condition of the user online information, specifically, the preset time length

N is a preset value preconfigured by an administrator, the administrator can make an adjustment of expansion or reduction according to a complex situation of an actual network architecture, f is a frequency count of user online information sent by the access device in unit time, and the unit time can be the latest 1 hour or the latest 4 hours.

The marking processing performed by the access device is used for indicating that the user online information does not receive the corresponding confirmation message sent by the network management platform. Specifically, the admission device may add the user online information that has not received the confirmation message to the transmission failure list, or set a flag to the user online information that has not received the confirmation message in a file that stores the transmitted user online information, such as a device behavior log of the admission device, or add an identifier, so as to set the flag information to the user online information that has not received the confirmation message to indicate that the user online information has not received the corresponding confirmation message.

Correspondingly, after the admission device receives the confirmation information returned by the network management platform, the marking cancellation processing can be performed on the user online information corresponding to the confirmation information, such as removing the user online information corresponding to the received confirmation information in a transmission failure list, or removing the identifier corresponding to the user online information or resetting the mark.

Step 403b, after a preset time period two, determining whether the user online information is still in the mark processing state, if so, entering step 404 b.

After the access device sets the marking information, it may determine whether the online user information is still in the marking state after a preset time length, where the preset time length for determining whether the online user information is still in the marking state may be equal to the preset time length for determining whether the marking is performed in step 402 b.

The admission device may re-determine the preset time length for determining whether the current judgment action is still in the marking process, and in the specific determination process, the admission device may determine a time period in which the current judgment action is generated, and then determine the preset time length for judging whether the current judgment action is still in the marking process according to the pre-configured time length corresponding to the time period, or may pre-configure the preset time length for judging whether the current judgment action is still in the marking process by an administrator, so that the admission device determines the preset time length for judging whether the current judgment action is still in the marking process according to the pre-configured time length.

Step 404b, the admission device sends the user online information still in the mark processing state to the network management platform again.

For the user online information which is still in the mark processing state after the preset time length is two, the access equipment can resend the user online information.

After the admission equipment sends the online user information still in the mark processing state to the network management platform again, the subsequent operation can be performed according to the condition that whether the network management platform completes synchronous updating and sends the confirmation information, and the specific process of the subsequent operation can be divided into the following two conditions:

under the condition that a network management platform receives user online information sent by access equipment and completes synchronous updating of online users in the network management platform based on the user online information, the network management platform can generate corresponding confirmation information so that the access equipment can determine the user online information corresponding to the confirmation information according to the received confirmation information, and an interaction process between the network management platform and the access equipment can specifically involve the following steps:

step 405b1, the network management platform returns confirmation information to the access device under the condition of completing synchronous update according to the received user online information.

In step 406b1, the admission apparatus that receives the acknowledgement cancels the marking process of the user online information corresponding to the acknowledgement.

After the admission device receives the confirmation information returned by the network management platform, the user online information corresponding to the confirmation information can be unmarked, such as removing the user online information corresponding to the received confirmation information from the transmission failure list, or removing the identifier corresponding to the user online information or resetting the identifier.

When a link fault occurs or network connection is abnormal or the network management platform fails to update based on the user online information, the access device cannot receive the confirmation information returned by the network management platform, and then the access device can send alarm information to an administrator under the condition that the confirmation information corresponding to the user online information cannot be received after a certain time, and the specific steps and processes are as follows:

step 405b2, sending an alarm message if the confirmation message corresponding to the user online information is not received after three preset durations.

In an embodiment, the alarm information may be directly sent to the administrator through a preconfigured contact manner, such as preconfigured mailbox information or contact telephone of the administrator, so that the administrator can timely know the abnormal condition when the access device determines that the confirmation information corresponding to the online user information is not received after a preset time period.

Specifically, the alarm information sent to the administrator may be pre-configured fixed information to reflect the failed access device to the administrator; or generating alarm information in real time according to the keywords in the abnormal condition log, such as a character string capable of reflecting the type of the abnormal condition, so that an administrator of the received alarm information can not only know the access equipment with the fault, but also know the abnormal condition in time.

In another embodiment, the alarm information may be sent to the administrator in a form of a pop-up window, and an abnormal situation related to that the confirmation information is not received is shown in the pop-up window, so as to improve the efficiency of the administrator in troubleshooting the abnormal situation, the user online information that the confirmation information cannot be received may be further explicitly received in the pop-up window, so that in an emergency situation, the administrator may remotely and directly process the response to the abnormal situation according to the obtained user online information, such as access of the user online information or sending the confirmation information to the access device by a simulation network management platform.

Fig. 5 is an interaction diagram illustrating a synchronization method of offline information of a user according to an exemplary embodiment of the present application, and as shown in fig. 5, the method may include:

step 501, the access device sends user offline information to the network management platform.

In an embodiment, the admission device may perform access control on the received trigger event of the user offline, and generate offline user information for sending to the network management platform after the trigger event of the user offline passes the access control.

In another embodiment, the admission device may periodically traverse the trigger event of the user offline through access control, determine the newly determined user offline event through access control in a period after the traversal of the period is finished, further generate user offline information corresponding to all the newly determined user offline events through access control in the period, and send the generated user offline information to the network management platform.

For example, in a traversal cycle, the admission device determines that the received offline triggering event a of the user a, the received offline triggering event B of the user B, the received offline triggering event C of the user C, and the received offline triggering event D of the user D pass through access control detection, which is different from the above-described embodiment that the user offline information corresponding to the offline triggering event a is generated immediately after the offline triggering event a of the user a passes through access control detection, in this embodiment, after a traversal cycle is completed, the network management device generates the offline user information x by combining the offline triggering event a, the offline triggering event B, the offline triggering event C, and the offline triggering event D determined in the cycle, so that the network management device can determine all newly accessed users in the traversal cycle, that is, the user a, the user B, the user C, and the user D, after receiving the offline user information x, and then the user login state information maintained by the network management platform is uniformly and synchronously updated at one time, and the offline user information does not need to be repeatedly generated for a plurality of offline triggering events, so that the operation process of the equipment is simplified, and the information synchronization efficiency of the user login state is improved.

Under the influence of emergencies such as network transmission abnormity, abnormal connection link and the like, in the practical application process, the network management platform can not be ensured to timely and accurately receive user offline information sent by each access device, and under the condition that the network management platform can accurately receive the user offline information sent by each access device, the network management platform can maintain an online user list maintained by the network management platform according to the received offline user information, namely, users receiving the offline user information are eliminated from the online user list, and the specific step process can refer to the following interaction process one:

step 502a, the network management platform completes synchronous update according to the received user offline information.

The network management platform can preferentially determine the identifier of the access device corresponding to the user offline information after receiving the user offline information sent by the access device, and further determine the storage area of the user login state of the received new access user based on the identifier of the access device, so that the user login state of the offline user contained in the offline user information from the same access device is stored in the storage area corresponding to the same identifier information. The network management platform can newly add the user information corresponding to the received offline user information in the storage area corresponding to the identifier of the access device so as to realize that the network management platform synchronizes the user login state of the newly accessed user.

Step 503a, the network management platform returns the confirmation information to the access device.

After the network management platform completes synchronous updating, the network management platform sends confirmation information corresponding to the user offline information to the access equipment, so that the access equipment receiving the confirmation information determines that the network management platform receives the sent user offline information, and completes updating operation of the user login state according to the received user offline information.

On the contrary, if the connection between the network management platform and the access device is affected by the abnormal condition and cannot be normally transmitted, the network management platform cannot normally receive the user offline information sent by the access device, or the network management platform receives the user offline information but cannot normally transmit the confirmation information to the access device, for this, the access device can mark the user offline information which is not received by the network management platform within the preset time length and resend the user offline information which is still in the mark processing state after another preset time length, and the specific step process can refer to the following interaction process two:

step 502b, the admission equipment marks the sent user offline information under the condition that the admission equipment determines that the confirmation information sent by the network management platform is not received after one of the preset durations.

The access device may record the time for sending the user offline information after sending the user offline information, or set a timing corresponding to the user offline information, so as to determine whether to receive the confirmation information corresponding to the sent user offline information after a preset duration.

In an embodiment, the preset duration may be a uniform time interval pre-configured by the administrator and applicable to any user offline information, or the admission device selects a duration corresponding to a time period according to the time period in which the time for sending the user offline information is located, such as at the sending time 11 of the user offline information: 30(24 hours) was at 9: 00-14:00, then the corresponding admission device may transmit time slot 9: 00-14: and setting the preconfigured time length corresponding to 00 as the preset time length corresponding to the offline information of the user.

In another embodiment, the admission device may generate a preset time length corresponding to the offline information of the user in real time according to the sending frequency condition of the offline information of the user, and specifically, the preset time length

N is a preset value preconfigured by an administrator, the administrator can make an adjustment of expansion or reduction according to a complex situation of an actual network architecture, f is a frequency count of user offline information sent by the access device in unit time, and the unit time can be the latest 1 hour or the latest 4 hours.

The marking processing performed by the access device is used for indicating that the user offline information does not receive the corresponding confirmation message sent by the network management platform. Specifically, the admission device may add the offline information of the user that did not receive the confirmation message to the transmission failure list, or set a flag to the offline information of the user that did not receive the confirmation message in a file, such as a device behavior log of the admission device, that stores the transmitted offline information of the user, or add an identifier, so as to set the flag information to the offline information of the user that did not receive the confirmation message to indicate that the offline information of the user did not receive the corresponding confirmation message.

Correspondingly, after the admission device receives the confirmation information returned by the network management platform, the user offline information corresponding to the confirmation information can be unmarked, such as removing the user offline information corresponding to the received confirmation information in a transmission failure list, or removing the identification or mark reset and the like corresponding to the user offline information.

Step 503b, after the preset time length two, it is determined whether the user offline information is still in the marking processing state, and if so, the step 404b is entered.

After the access device sets the flag information, it may determine whether the offline user information is still in the flag processing state after a preset time duration, where the preset time duration for determining whether the offline user information is still in the flag processing state may be equal to the preset time duration for determining whether the flag processing is performed in step 402 b.

Step 504b, the admission device sends the user offline information still in the marking processing state to the network management platform again.

For the user offline information still in the marked processing state after the preset time length two, the access device can resend the user offline information.

After the admission device sends the offline user information still in the mark processing state to the network management platform again, the admission device can perform subsequent operation according to the condition whether the network management platform completes synchronous updating and sends confirmation information, and the specific process of the subsequent operation can be divided into the following two conditions:

under the condition that the network management platform receives user offline information sent by the access equipment and completes synchronous updating of offline users in the network management platform based on the user offline information, the network management platform can generate corresponding confirmation information, so that the access equipment can determine the user offline information corresponding to the confirmation information according to the received confirmation information, and an interaction process between the network management platform and the access equipment can specifically involve the following steps:

step 505b1, the network management platform returns confirmation information to the access device under the condition of completing synchronous update according to the received user offline information.

In step 506b1, the admission device that received the confirmation information cancels the marking of the offline information of the user corresponding to the confirmation information.

After the admission device receives the confirmation information returned by the network management platform, the user offline information corresponding to the confirmation information may be unmarked, such as removing the user offline information corresponding to the received confirmation information in a transmission failure list, or removing the identifier or mark reset corresponding to the user offline information.

When a link failure occurs or network connection is abnormal or the network management platform fails to update based on the user offline information, the admission equipment cannot receive confirmation information returned by the network management platform, and then the admission equipment can send alarm information to an administrator under the condition that the admission equipment still cannot receive the confirmation information corresponding to the user offline information after a certain time, wherein the specific steps and processes are as follows:

step 505b2, sending an alarm message if the confirmation message corresponding to the user offline message is not received after the preset time period is three.

In an embodiment, the alarm information may be directly sent to the administrator through a preconfigured contact manner, such as preconfigured mailbox information or contact telephone of the administrator, so that the administrator can know the abnormal condition in time when the access device determines that the confirmation information corresponding to the offline user information is not received after the preset time period elapses.

In another embodiment, the alarm information may be sent to the administrator in a form of a popup window, and an abnormal situation related to the non-reception of the confirmation information is shown in the popup window, and in order to improve the efficiency of the administrator for the abnormal situation, the user offline information that fails to receive the confirmation information may be further specified in the popup window, so that in an emergency, the administrator may remotely and directly handle the reply abnormal situation according to the obtained user offline information, such as the access of the user offline information or the simulation of the network management platform sending the confirmation information to the access device.

Fig. 6 is an interaction diagram illustrating a method for synchronizing user state information in an abnormal restart condition of an admission device according to an exemplary embodiment of the present application, where as shown in fig. 6, the method may include:

step 601, the access device sends abnormal restart information to the network management platform after the abnormal restart is completed.

In an embodiment, if the access device is restarted due to an abnormal accident, the access device may automatically generate abnormal restart information including identification information of the access device itself after the abnormal restart is completed, and send the generated abnormal restart information to the network management platform.

Under the influence of emergencies such as network transmission abnormity, abnormal connection link and the like, in the practical application process, the network management platform cannot be ensured to be capable of timely and accurately receiving abnormal restart information sent by each access device, on the contrary, if the network management platform can accurately receive the abnormal restart information sent by each access device, based on the received abnormal restart information, the network management platform can remove the user login state which is maintained in the network management platform and corresponds to the access device sending the abnormal restart information, and the specific step process can refer to the following interaction process one:

step 602a, the network management platform determines the abnormal restart information sent by the access device, and the network management platform removes the user login state corresponding to the abnormal restart information.

After receiving the abnormal restart information sent by the access equipment, the network management platform can preferentially determine the identifier of the access equipment corresponding to the abnormal restart information, further determine a storage area of a user login state corresponding to the identifier of the access equipment based on the identifier of the access equipment, further remove all the user login states in the storage area, so as to remove the user login state related to the user accessed by the access equipment corresponding to the abnormal restart information, and keep the network management platform and the access equipment which just completes the abnormal restart synchronously updated about the user login state which is not in the online state.

Step 603a, the network management platform sends confirmation information to the access device.

After the network management platform completes the synchronous update, the network management platform sends confirmation information corresponding to the online information of the user to the access equipment, so that the access equipment receiving the confirmation information determines that the network management platform completes the synchronous update of the user state information.

However, under the condition that the network connection or the link connection between the network management platform and the access device cannot be normally transmitted due to an abnormal condition, the network management platform cannot normally receive the abnormal restart information sent by the access device, or the network management platform receives the abnormal restart information but cannot normally transmit the abnormal restart information to the access device, and accordingly, the access device can mark the abnormal restart information of the network management platform which is not received within the preset time length and resend the abnormal restart information of another network management platform which is not received within the preset time length, and the specific step process can refer to the following interaction process two:

step 602b, the admission device marks the transmitted abnormal restart information when determining that the confirmation information transmitted by the network management platform is not received after one of the preset durations.

The admission device may record the time for sending the abnormal restart information after sending the abnormal restart information, or set a timing corresponding to the abnormal restart information to determine whether the confirmation information corresponding to the sent abnormal restart information is received after a preset time period.

In an embodiment, the preset duration may be a fixed duration preconfigured by the administrator; in another embodiment, the preset duration may be a time period of the restart time of the abnormal condition, and the preconfigured duration corresponding to the time period is called to determine whether to perform the marking processing on the sent abnormal restart information.

The marking processing performed by the access device is used for indicating that the abnormal restart information does not receive the corresponding confirmation message sent by the network management platform. Specifically, the admission device may add the abnormal restart information for which the confirmation message is not received to the transmission failure list, or set a flag to the abnormal restart information for which the confirmation message is not received in a file, such as a device behavior log of the admission device, storing the transmitted abnormal restart information, or add an identifier to indicate that the corresponding confirmation message is not received by setting the flag to the abnormal restart information for which the confirmation message is not received.

Correspondingly, after the admission device receives the confirmation information returned by the network management platform, the access device may perform cancellation marking processing on the abnormal restart information corresponding to the confirmation information, such as removing the abnormal restart information corresponding to the received confirmation information in the transmission failure list, or removing the identifier corresponding to the abnormal restart information or marking resetting.

Step 603b, after a preset time period two, determining whether the abnormal restart information is still in the flag processing state, and if so, entering step 604 b.

After the access device sets the flag information, it may determine whether the abnormal state information is still in the flag processing state after a preset time length elapses, where the preset time length for determining whether the abnormal state information is still in the flag processing state may be equal to the preset time length for determining whether the flag processing is performed in step 602 b.

In step 604b, the admission device retransmits the abnormal restart information still in the flag processing state.

And for the abnormal restarting information which is still in the mark processing state after the preset duration two, the access equipment can resend the abnormal restarting information.

After the admission equipment sends the abnormal restart information still in the mark processing state to the network management platform again, the subsequent operation can be performed according to the condition that whether the network management platform completes synchronous updating and sends the confirmation information, and the specific process of the subsequent operation can be divided into the following two conditions:

when the network management platform receives the abnormal restart information sent by the access device and completes the removal of the corresponding user login state information based on the abnormal restart information, the network management platform may generate corresponding confirmation information, so that the access device can determine the abnormal restart information corresponding to the confirmation information according to the received confirmation information, and an interaction process between the network management platform and the access device may specifically involve the following steps:

step 605b1, the network management platform sends confirmation information to the access device when the network management platform completes the removal of the user login state corresponding to the received abnormal restart information.

In step 606b1, the admission apparatus that received the acknowledgement cancels the marking of the abnormal restart information corresponding to the acknowledgement.

After the admission device receives the confirmation information returned by the network management platform, the access device may perform cancellation marking processing on the abnormal restart information corresponding to the confirmation information, such as removing the abnormal restart information corresponding to the received confirmation information in the transmission failure list, or removing the identifier corresponding to the abnormal restart information or marking reset.

When a link failure occurs or network connection is abnormal or the network management platform fails to update based on abnormal restart information, the admission equipment cannot receive confirmation information returned by the network management platform, and then the admission equipment can send alarm information to an administrator under the condition that the admission equipment still cannot receive the confirmation information corresponding to the abnormal restart information after a certain time, wherein the specific steps and processes are as follows:

step 605b2, the admission device sends an alarm message when it has not received the confirmation message corresponding to the abnormal restart message after a preset time period.

In an embodiment, the alarm information may be directly sent to the administrator through a preconfigured contact manner, such as preconfigured mailbox information or contact telephone of the administrator, so that the administrator can know the abnormal condition in time when the access device determines that the confirmation information corresponding to the abnormal restart information is not received after a preset time period.

In another embodiment, the alarm information may be sent to the administrator in a form of a popup window, and an abnormal situation related to that the confirmation information is not received is shown in the popup window, and in order to improve the efficiency of the administrator for the abnormal situation, the abnormal restart information that the confirmation information cannot be received may be further explicitly received in the popup window, so that in an emergency, the administrator may remotely and directly process the reply abnormal situation according to the obtained user online information, such as access of the user online information or a simulation network management platform sending the confirmation information to the access device.

Fig. 7 is an interaction diagram illustrating a method for synchronizing user status information in an abnormal restart condition of a network management platform according to an exemplary embodiment of the present application, where as shown in fig. 7, the method may include:

step 701, the network management platform sends abnormal restart information to the access device after the abnormal restart is completed.

In an embodiment, if the network management platform is restarted due to an abnormal accident, the network management platform may automatically generate abnormal restart information containing identification information of the network management platform after the abnormal restart is completed, and send the generated abnormal restart information to the access device.

Under the influence of the emergencies such as abnormal network transmission, abnormal connection link and the like, the access device can not be ensured to accurately receive the abnormal restarting information sent by the network management platform in time in the practical application process, so that the interaction process I is adopted, after the network management device sends the abnormal restarting information, the access device receiving the abnormal restarting information returns confirmation information to indicate that the access device can normally receive the abnormal restarting information and respond.

Step 702a, after the admission device receives the abnormal restart information sent by the network management platform, the admission device sends confirmation information to the network management platform.

Step 703a, the admission device sends the user login state information to the network management platform.

The user login state information can comprise user information of the access equipment end in an online state, so that the network management platform updates the user information which is online through the access equipment according to the received user login state information; or the user login state information may include user information currently in an online state and user information that has been in an online state within a preset time recently, so that the user information in the online state within the preset time recently can be traced through the network management platform.

Step 704a, based on the received user login status information of the online user, the network management platform stores the user login status information.

The network management platform maintains the user login state information on each access device connected with the network management platform. In an embodiment, the network management platform may maintain user login state information on each access device connected thereto. In an embodiment, the network management platform may establish a list and record user information accessed through each access device in the list, so as to implement the network management platform to synchronously update the user login state of a new user accessed through each access device.

Step 702b, the network management platform marks the sent abnormal restart information when receiving the confirmation information sent by the access device for one of the preset durations.

The network management platform may record the time for sending the abnormal restart information after sending the abnormal restart information, or set a timing corresponding to the abnormal restart information, so as to determine whether to receive the confirmation information corresponding to the sent abnormal restart information after a preset time period.

And the marking processing performed by the network management platform is used for indicating that the abnormal restarting information does not receive the corresponding confirmation message sent by the access equipment. Specifically, the network management platform may add the abnormal restart information that has not received the confirmation message to the transmission failure list, or set a flag to the abnormal restart information of the non-received confirmation message in a file that stores the transmitted abnormal restart information, such as a device behavior log of the network management platform, or add an identifier, so that the abnormal restart information that has not received the confirmation message sets the flag information to indicate that the abnormal restart information has not received the corresponding confirmation message.

Correspondingly, after the network management platform receives the confirmation information returned by the admission device, the abnormal restart information corresponding to the confirmation information may be unmarked, such as removing the abnormal restart information corresponding to the received confirmation information from the transmission failure list, or removing the identifier corresponding to the abnormal restart information or resetting the identifier.

In step 703b, after the preset duration two, the network management platform determines whether the abnormal restart information is still in the flag processing state, and if so, the process goes to step 704 b.

After the network management platform sets the flag information, it may determine whether the abnormal state information is still in the flag processing state after a preset time length elapses, where the preset time length for determining whether the abnormal state information is still in the flag processing state may be equal to the preset time length for determining whether the flag processing is performed in step 702 b.

The network management platform can re-determine whether the preset time length still in the marking processing is determined, in the specific determination process, the network management platform can determine the time period of the current judgment action, and then the time period is determined as the preset time length for judging whether the marking processing is still performed according to the pre-configured time length corresponding to the time period, or an administrator can pre-configure the preset time length for judging whether the marking processing is still performed, so that the network management platform determines the preset time length for judging whether the marking processing is still performed according to the pre-configured time length.

Step 704b, the network management platform resends the abnormal restart information still in the mark processing state.

And for the abnormal restarting information which is still in the mark processing state after the preset duration two, the network management platform can resend the abnormal restarting information.

After the network management platform sends the abnormal restart information still in the mark processing state to the access device again, the network management platform can perform subsequent operation according to the condition that whether the access device completes synchronous update and sends the confirmation information, and the specific process of the subsequent operation can be divided into the following two conditions:

when the access device receives the abnormal restart information sent by the network management platform and completes the removal of the corresponding user login state information based on the abnormal restart information, the access device may generate corresponding confirmation information, so that the network management platform can determine the abnormal restart information corresponding to the confirmation information according to the received confirmation information, and an interaction process between the network management platform and the access device may specifically involve the following steps:

step 705b1, the admission device sends the acknowledgement information to the network management platform.

Step 706b1, the network management platform that receives the confirmation message cancels the marking process of the abnormal restart message corresponding to the confirmation message.

After the network management platform receives the confirmation information returned by the admission device, the abnormal restart information corresponding to the confirmation information may be unmarked, such as removing the abnormal restart information corresponding to the received confirmation information from the transmission failure list, or removing the identifier corresponding to the abnormal restart information or resetting the identifier.

When a link failure occurs or network connection is abnormal or the network management platform fails to update based on abnormal restart information, the network management platform cannot receive confirmation information returned by the access device, and then the network management platform can send alarm information to an administrator under the condition that the network management platform still cannot receive the confirmation information corresponding to the abnormal restart information after a certain time, and the specific steps and processes are as follows:

step 705b2, the network management platform sends an alarm message when it has not received the confirmation message corresponding to the abnormal restart message after a preset time period.

In an embodiment, the alarm information may be directly sent to the administrator through a preconfigured contact manner, such as preconfigured mailbox information or contact phone of the administrator, so that the administrator can timely know the abnormal condition when the network management platform determines that the confirmation information corresponding to the abnormal restart information is not received after a preset time period.

Specifically, the alarm information sent to the administrator may be pre-configured fixed information to reflect the failed network management platform to the administrator; or generating alarm information in real time according to the keywords in the abnormal condition log, such as a character string capable of reflecting the type of the abnormal condition, so that an administrator of the received alarm information can not only know the network management platform with the fault, but also know the abnormal condition in time.

In another embodiment, the alarm information may be sent to the administrator in a form of a popup window, and an abnormal situation related to the non-reception of the confirmation information is shown in the popup window, and in order to improve the efficiency of the administrator for the abnormal situation, the abnormal restart information in which the confirmation information is not received may be further specified in the popup window.
