Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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 the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1, a schematic structural diagram of a backup networking of a relay and release BRAS (BRAS device) provided in this embodiment of the present application includes: main user plane/forwarding plane (UP), standby UP, Management and organization (MANO), and Control Plane (CP); wherein, the main UP and the standby UP pre-store the same user table entry. When the networking normally works, the main UP monitors the user traffic of each user managed by the user table entry, and when the user traffic changes, the main UP reports the corresponding user traffic information to the CP at a preset rate, and meanwhile, the main UP is also used for forwarding the user flow direction, namely forwarding the user flow direction of the user side to the destination side and forwarding the user traffic returned by the destination side to the user side; the user flow information refers to the traffic generated by the user accessing the network. And after receiving the user flow information reported by the main UP, the CP carries out flow statistics and charging. When the MANO detects the link failure of the main UP and the CP, the MANO sends a main-standby switching command to the main UP, the CP and the standby UP respectively for performing main-standby switching between the main UP and the standby UP, and after the main-standby switching is completed, the standby UP is used as a new main UP to monitor user traffic and report the work of monitoring user traffic information and forwarding the user traffic to the CP when the user traffic changes.
In the process of primary-secondary switching, the following two mechanisms are added in the embodiment of the application to reduce the error value of the user traffic information counted by the CP before and after the primary-secondary switching and improve the accuracy of counting and charging the user traffic information by the control plane CP before and after the primary-secondary switching, and the two mechanisms are as follows:
1. after the main UP successfully reports the user traffic information to the CP each time, a piece of successfully reported user traffic information (hereinafter, referred to as first user traffic information) is locally stored, where after the main UP successfully reports the user traffic information to the CP for multiple times, the successfully reported user traffic information at the next time replaces the successfully reported user traffic information at the previous time. Meanwhile, when the main UP switches between main and standby (that is, when a main/standby switching command sent by the MANO is received), user traffic information monitored at the current time point is stored, and the user traffic information is user traffic information monitored in the current period (hereinafter, referred to as second user traffic information).
2. A link for detection is added between the main UP and the standby UP, and data can be transmitted between the main UP and the standby UP through the link. Here, the link Detection mode may be implemented by a network protocol (Bidirectional Forwarding Detection, bfd) for detecting a fault between two Forwarding points, and bfd is in a suppression state under a normal condition. The following describes a method and an apparatus for synchronizing user data according to an embodiment of the present application based on two additional mechanisms.
As shown in fig. 2, a synchronization method for user data provided in an embodiment of the present application is applied to a main forwarding plane UP, and the method includes:
s101, if a main/standby exchange instruction is received, acquiring reference user flow information; wherein, the reference user traffic information includes difference user traffic information monitored by the main UP but not reported to the control plane CP.
In the embodiment of the present application, after detecting a link failure between a main UP and a CP, a MANO may issue a main/standby switching instruction to the main UP, a standby UP, and the CP, and after receiving the main/standby switching instruction, the standby UP may send a detection message (specifically, a detection message) to the main UP, and if receiving the detection message, the main UP may feed back a response message to the standby UP. After receiving the response information fed back by the main UP, the standby UP confirms that the link detection between the standby UP and the main UP is successful, at this time, the standby UP sends flow request information to the main UP, and after receiving the flow request information, the main UP synchronizes the acquired reference user flow information to the standby UP through the link which is successful in detection.
Here, the reference user traffic information may be difference user traffic information that is monitored by the main UP in the current period and is not reported to the control plane CP, or may be second user traffic information that is stored by the main UP and monitored when the main-standby switching instruction is received (where the second user traffic information includes the difference user traffic information and first user traffic information that is reported to the CP in the current period).
In the embodiment of the present application, the number of users managed by the user entry of the main UP is multiple, and when monitoring that the user traffic changes, the main UP reports the corresponding user traffic information to the CP at a preset rate. For example, when the number of users managed by the main UP is 10, and the rate at which the main UP reports the user traffic information to the CP is 2 users/s (that is, the main UP reports the user traffic information of two users to the CP within 1 s), then the user traffic information upload period of the main UP is 5s (that is, the main UP can report all the user traffic information of 10 users to the CP within 5 s). When the user traffic of 10 users changes, in the first 5s period (i.e., from 1 st to 5 th), the main UP reports the user traffic information of the user 1 and the user 2 to the CP in the 1 st s, the main UP reports the user traffic information of the user 3 and the user 4 to the CP in the 2 nd s, and so on, and the main UP reports the user traffic information of the user 9 and the user 10 to the CP in the 5 th s. In practice, when the main UP reports the user traffic information after the 2 nd s, the user traffic of the user 1 and the user 2 may continue to change, and so on, when the main UP reports the user traffic information at the 5 th s, the user traffic of the user 1 to the user 8 may continue to change. Thus, in the second 5s period (i.e. in the 6 th to 10 th s), the main UP first reports the user traffic information of the user 1 and the user 2 monitored in the current period at the 6 th s, and reports the user traffic information of the user 3 and the user 4 monitored in the current period at the 7 th s, at this time, the user traffic of the user 1 and the user 2 may still change, if the main UP is switched between the main and standby at the 8 th s, the difference user traffic information at this time includes the user traffic information of the user 5 to the user 10 monitored in the current period and the user traffic information of the user 1 to the user 4 monitored in the current period. The second user traffic information includes the user traffic information reported to the CP by the users 1 to 10 currently (at the 8 th time) and the difference user traffic information.
S102, sending the reference user flow information to the standby UP so that the standby UP can report the reference user flow information to the CP.
Here, if the traffic request information sent by the standby UP is used to request the differential user traffic information, the main UP reports the acquired differential user traffic information to the CP. If the traffic request information sent by the main UP is used for requesting the second user traffic information, the main UP reports the acquired second user traffic information to the CP.
Further, in the synchronization method for user data provided in the embodiment of the present application, the reference user traffic information further includes first user traffic information that has been reported to the CP; the reference user traffic information is second user traffic information stored by the main UP and monitored when the main-standby switching instruction is received. Correspondingly, step 102 sends the reference user traffic information to the standby UP, including:
and if the traffic request information sent by the standby UP is received within the time period from the receiving of the main/standby exchange instruction to the completion of the main/standby switching, sending reference user traffic information including the first user traffic information and the difference user traffic information to the standby UP.
In the embodiment of the application, when the main UP receives the main/standby switching instruction, the stored second user traffic information monitored when the main/standby switching instruction is received is firstly acquired, and if the detection message and the traffic request message from the standby UP are received before the main/standby switching is completed, the acquired second user traffic information is directly synchronized to the standby UP, so that the accuracy of counting and charging the user traffic information by the control plane CP before and after the main/standby switching is improved, and the response speed of the standby UP is improved.
If the main UP receives the detection message from the standby UP after the main-standby switching is completed, the main UP synchronizes the differential value user traffic information which is monitored in the current period and is not reported to the control plane CP to the standby UP after receiving the traffic request message. After receiving the traffic request message overtime, the primary UP synchronizes differential user traffic information to the backup UP because the backup UP has already obtained first user traffic information reported to the CP from the CP as a new primary UP after the primary-backup switching is completed, and monitors the updated traffic of the user based on the first user traffic information.
Further, as shown in fig. 3, in the synchronization method for user data provided in this embodiment of the present application, when the reference user traffic information may also be difference user traffic information that is monitored by the main UP but is not reported to the control plane CP, step 101 obtains the reference user traffic information, where the step includes:
s201, acquiring stored first user traffic information reported to the CP and stored monitored second user traffic information; wherein the second user traffic information comprises the first user traffic information and the difference user traffic information;
in this embodiment of the present application, when receiving a primary/secondary switching instruction, a primary UP first acquires second user traffic information monitored in a current period, and if a detection message sent by a secondary UP is not received before the primary/secondary switching is completed, acquires first user traffic information that has been reported to a CP in the current period.
Or, when receiving the primary/secondary switching command, the primary UP simultaneously obtains the first user traffic information reported to the CP in the current period and the stored second user traffic information monitored in the current period.
S202, according to the first user traffic information and the second user traffic information, determining difference value user traffic information which is monitored by the main UP and is not reported to a control plane CP as the reference user traffic information.
In this embodiment, the second user traffic information includes the first user traffic information and the difference user traffic information. After acquiring the first user traffic information and the second user traffic information, the main UP calculates a difference value between a user traffic value in the first user traffic information and a user traffic value in the second user traffic information, and uses the difference value user traffic information corresponding to the difference value as reference user traffic information.
As an implementation manner, if the main UP receives the detection message and the traffic request information from the standby UP after the main/standby switching is completed, the acquired differential value user traffic information is synchronized to the standby UP. Here, the contents of the traffic request messages sent by the standby UP before the completion of the primary-secondary switching and after the completion of the primary-secondary switching are different, the request message before the completion of the primary-secondary switching is used for requesting the second user traffic information, and the request message after the completion of the primary-secondary switching is used for requesting the difference user traffic information.
In addition, in this embodiment of the present application, as another implementation manner, no matter whether the main UP receives traffic request information from the standby UP before the main-standby switching is completed or receives traffic request information from the standby UP after the main-standby switching is completed, the main UP synchronizes the differential value user traffic information to the standby UP. Here, the traffic request information sent by the main UP includes the same contents, and is used for requesting the differential user traffic information.
In the method for synchronizing user data provided by the embodiment of the application, when a main UP receives a main/standby switching instruction, the main UP obtains reference user flow information at least including differential user flow information which is monitored in a current period and is not reported to a control plane CP, and reports the reference user flow information to the control plane CP through the standby UP, so that the flow for counting and charging of the CP includes the differential user flow information which cannot be reported when the main UP is switched between the main and standby, thereby reducing the error value of the user flow information counted by the CP before and after the main/standby switching, and improving the accuracy of counting and charging of the user flow information by the control plane CP before and after the main/standby switching.
As shown in fig. 4, an embodiment of the present application further provides a method for synchronizing user data, where the method is applied to a standby forwarding plane UP, and the method includes:
s301, receiving reference user traffic information sent by a main forwarding plane UP, wherein the reference user traffic information comprises difference value user traffic information which is monitored by the main UP when receiving a main/standby switching instruction and is not reported to a control plane CP.
In a specific embodiment, after detecting a link failure between a main UP and a CP, a MANO may issue a main/standby switching command to the main UP, a standby UP, and the CP, and after receiving the main/standby switching command, the standby UP may send a detection message (specifically, a detection message) to the main UP, and if receiving the detection message, the main UP may feed back a response message to the standby UP. After receiving the response information fed back by the main UP, the standby UP confirms that the link detection between the standby UP and the main UP is successful, at this time, the standby UP sends flow request information to the main UP, and after receiving the flow request information, the main UP synchronizes the acquired reference user flow information to the standby UP through the link.
In this embodiment, the reference user traffic information may be the difference user traffic information, or may be second user traffic information (where the second user traffic information includes the difference user traffic information) stored by the main UP and monitored when the main-standby switching instruction is received.
S302, reporting the reference user flow information to the CP, so that the CP carries out flow statistics and charging processing based on the reference user flow information.
In the embodiment of the application, after receiving the reference user traffic information, the standby UP can directly report the reference user traffic information to the reference user traffic information. Or, based on the received reference user traffic information and the updated user traffic information in the current period, the actual user traffic information that needs to be reported to the control plane CP in the current period is counted, and then the actual user traffic information is reported to the CP.
Further, as shown in fig. 5, when the reference user traffic information is the difference user traffic information, in the method for synchronizing user data provided in the embodiment of the present application, step S302 of reporting the reference user traffic information to the CP includes:
s401, sending flow request information to the CP, wherein the flow request information is used for requesting the main UP to report user flow information to the CP.
In the embodiment of the application, after receiving the main/standby switching command, the standby UP sends a detection message to the main UP and requests the CP for reporting user traffic information to the CP for the last time by the main UP.
After receiving the user traffic information reported by the main UP which normally works in each period, the CP replaces the user traffic information which is reported successfully in the previous period on the CP with the user traffic information received in the current period. Therefore, after receiving the primary/secondary switching command, the CP stores the user traffic information reported by the primary UP, which is reported by the primary UP for the last time.
Here, the user traffic information reported to the CP by the main UP for the last time is the user traffic information reported to the CP by the main UP in the current period of receiving the main/standby switching instruction.
S402, counting the actual user flow information which needs to be reported to the control plane CP in the current period based on the reported user flow information, the difference value user flow information in the reference user flow information and the updated user flow information.
After receiving reported user traffic information returned by the CP and switching to a new main UP, the standby UP monitors updated user traffic information of users managed by its own user table entry in the current period, and increases the updated user traffic information monitored in the current period on the basis that the sum of the reported user traffic information and the difference user traffic information is a base value, to obtain actual user traffic information that needs to be reported to the control plane CP in the current period.
And S403, reporting the actual user traffic information to the CP.
Here, the CP updates the stored historical user traffic information after receiving the actual user traffic information.
Further, as shown in fig. 6, in the synchronization method for user data provided in this embodiment of the present application, the reference user traffic information further includes user traffic information reported to the CP by the main UP, where the reference user traffic information is second user traffic information monitored by the main UP when receiving the main/standby switching instruction; step S302, reporting the reference user traffic information to the CP, including:
s501, counting the actual user traffic information required to be reported to the control plane CP in the current period based on the reference user traffic information including the reported user traffic information and the difference user traffic information and the updated user traffic information.
After receiving the second user traffic information synchronized with the main UP and switching to a new main UP, the standby UP monitors the updated user traffic information of the user managed by its user table entry in the current period, increases the updated user traffic information monitored in the current period on the basis of taking the second user traffic information as a base value, and counts to obtain the actual user traffic information required to be reported to the control plane CP in the current period.
And S502, reporting the actual user flow information to the CP.
Here, the CP updates the stored historical user traffic information after receiving the actual user traffic information.
In the method for synchronizing user data provided by the embodiment of the application, when a main UP receives a main/standby switching instruction, the main UP obtains reference user flow information at least including differential user flow information which is monitored in a current period and is not reported to a control plane CP, and reports the reference user flow information to the control plane CP through the standby UP, so that the flow for counting and charging of the CP includes the differential user flow information which cannot be reported when the main UP is switched between the main and standby, thereby reducing the error value of the user flow information counted by the CP before and after the main/standby switching, and improving the accuracy of counting and charging of the user flow information by the control plane CP before and after the main/standby switching.
In fig. 7, UP1 is the main UP, UP2 is the standby UP, UP1 is connected to CP through core router CR (CR) 1 and the switch, UP2 is connected to CP through CR2 and the UP1 and UP2 may be connected directly or through CR1, CR2 and the switch. Wherein:
after receiving a main/standby switching instruction sent by the MANO, the UP1 returns response information of the received main/standby switching instruction to the MANO; at the same time, UP1 also reports the stored second user traffic information to the CP and informs the CP to synchronize the second user traffic information to the standby UP. If the UP1 receives traffic request information from the UP2 before the master-slave switching is completed, synchronizing the stored second user traffic information to the UP2, and if the UP1 receives traffic request information from the UP2 after the master-slave switching is completed, synchronizing the difference value user traffic information of the second user traffic information from the first user traffic information reported to the CP in the current period to the UP 2.
After receiving the main/standby switching command sent by the MANO, the UP2 sends a probe message to the UP1, and if response information from the UP1 for the probe message is received before the main/standby switching is completed, sends first traffic request information for requesting second user traffic information to the UP 1. After receiving the UP1 synchronized second user traffic information, the UP2 stops sending the detection message to the UP1 (i.e., closes the detection mechanism), counts the actual user traffic information that needs to be reported to the control plane CP in the current period by using the second user traffic information as a base value, and sends the actual user traffic information counted in the current period to the CP. UP2, upon receiving the master-slave switching command sent by the MANO, also sends second traffic request information to the CP requesting the first user traffic information, after receiving the first user traffic information sent by the CP, if the response information from the UP1 for the probe message is not received before the active/standby switching is completed, the probe message is continuously sent to the UP1 until the response information from the UP1 for the probe message is received, a third request information for requesting the differential user traffic information is sent to the UP1, after receiving the difference user traffic information returned by the UP1, stopping sending the detection message to the UP1 (i.e. closing the detection mechanism), and meanwhile, counting the actual user flow information which needs to be reported to the control plane CP in the current period by taking the first user flow information and the difference value user flow information as basic values, and counting the actual user flow information counted in the current period to the CP.
After receiving a main/standby switching instruction sent by a MANO, a CP changes its own configuration information into configuration information matching a new main UP to be switched to (specifically, changes the configuration of a tunnel module, i.e., changes a tunnel with an original main UP into a tunnel with the new main UP), and if receives second traffic request information from UP1 for requesting first user traffic information, synchronizes the first user traffic information successfully reported by UP1 to UP2, and at the same time, sends first traffic request information for requesting second user traffic information to UP1, and after receiving the second user traffic information synchronized by UP1, stops sending a detection message (i.e., closes a detection mechanism) to UP1, and counts actual user traffic information required to be reported to a control plane CP in a current period with the second user traffic information as a base value.
In the method for synchronizing user data provided by the embodiment of the application, when a main UP receives a main/standby switching instruction, the main UP obtains reference user flow information at least including differential user flow information which is monitored in a current period and is not reported to a control plane CP, and reports the reference user flow information to the control plane CP through the standby UP, so that the flow for counting and charging of the CP includes the differential user flow information which cannot be reported when the main UP is switched between the main and standby, thereby reducing the error value of the user flow information counted by the CP before and after the main/standby switching, and improving the accuracy of counting and charging of the user flow information by the control plane CP before and after the main/standby switching.
It should be noted that, when detecting a link failure of UP1 by a MANO, whether the link between UP1 and a user side is disconnected or detecting a link between UP1 and a CP is disconnected, the MANO is a primary/secondary exchange instruction sent to UP1, UP2 and the CP, and the UP1 does not know a specific link failure point when receiving the primary/secondary exchange instruction, so the UP1 reports the second user traffic information to the CP when receiving the primary/secondary exchange instruction, and if a failure problem occurs between UP1 and the user side, the UP1 can successfully report the second user traffic information to the CP, and because a failure occurs between UP1 and the user side, the UP1 does not monitor updated user traffic information when receiving the primary/secondary exchange instruction, and therefore, the second user traffic information is the same as the first user traffic information.
At this time, after the link probing between the UP1 and the UP2 is successful, the UP1 may synchronize the second user traffic information to the UP2 through the probing link, and the UP2 does not need to request the second user traffic information to the CP after receiving the second user traffic information synchronized with the UP 1. Correspondingly, if the link probing between the UP1 and the UP2 fails, the UP1 may report the second user traffic information to the CP, which is synchronized by the CP to the UP2, and the UP2 continues to operate based on the CP-synchronized second user traffic information.
