Description

Method and device for realizing backup

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for implementing backup.

Background

At present, when the insurmountable forces such as earthquake, fire and the like are faced, local data backup cannot guarantee that backup data are not lost, and the requirements of operators on high availability, real-time performance and safety of service systems cannot be met. In order to deal with the above situation and reduce enterprise loss, the industry proposes a technical idea of disaster recovery from different places.

The CP disaster recovery is a remote disaster recovery technology applied to the vBRAS forwarding and control separation networking. Multiple CPs are in Data centers (abbreviated as DC) with different address positions, and double-machine backup is carried out through the multiple CPs so as to realize remote disaster recovery, so that when one DC fails or has a disaster, another DC can quickly take over user services.

In a vBRAS forwarding and control separation networking, the existing CP disaster recovery mode comprises a 1:1 backup type and a 1+1 backup type.

Under the 1:1 backup type, the main CP is the current working CP, and the standby CP is used for backup. The implementation process specifically comprises the following steps: and respectively creating a CP disaster backup group in the two CPs which are mutually main and backup. And a main CP disaster backup group is established in the main CP, a backup CP disaster backup group is established in the backup CP, and the UP ranges managed by the main CP disaster backup group and the backup CP disaster backup group are consistent. When the main CP fails, the main CP disaster recovery group can not provide service for the user service on the UP continuously. At this time, the backup CP takes over the work of the main CP and starts the backup CP disaster backup group to manage the user service on UP.

Under the 1+1 backup type, the main CP and the standby CP are all the current working CP. The implementation process specifically comprises the following steps: two CP disaster recovery backup groups are respectively established in the main CP and the backup CP. The CP disaster backup groups with the same name in the main CP and the standby CP disaster backup groups are respectively used as the main CP disaster backup group and the standby CP disaster backup group, the UP ranges managed by the main CP disaster backup group and the standby CP disaster backup group are consistent, and the main and standby states of different CP disaster backup groups in the same CP are different. For example, a main CP in the DC1 creates a main CP disaster recovery group a and a backup CP disaster recovery group B, the UP ranges managed by the main CP disaster recovery group a are UP1 and UP2, and the UP ranges managed by the backup CP disaster recovery group B are UP3 and UP 4; similarly, the backup CP in the DC2 creates a backup CP disaster backup group a and a main CP disaster backup group B, the UP ranges managed by the backup CP disaster backup group a are UP1 and UP2, and the UP ranges managed by the main CP disaster backup group B are UP3 and UP 4. At the same time, different CPs manage user services on part of UP, reduce the service pressure of single points, and improve the utilization rate of network equipment.

The two backup types are both the CP device in one DC to provide backup service only for the CP device in the other DC at the same time, and the utilization rate of the device resource of the DC where the backup CP is located is low.

The following describes a method for implementing a backup provided in an embodiment of the present application in detail. Referring to fig. 1, fig. 1 is a flowchart of a method for implementing backup according to an embodiment of the present application. The method is applied to the first CP. The implementation method of the backup provided by the embodiment of the application may include the following steps.

Step 110, when multiple second CPs fail or the link between the UPs indicated by the UP identifier in the second CP and the main CP disaster recovery group fails, acquiring the group identifier of the disaster recovery channel group bound to the address of each second CP according to the address of each second CP.

Specifically, the N:1 backup mesh network includes a plurality of CPs that are active and standby with each other, and each CP is in one DC. For example, the first CP is within a first DC, all other DCs except the first DC are collectively referred to as second DCs, and one second CP is included in each second DC. It is understood that the second DC may include a third DC, a fourth DC, etc., and the second CP includes a third CP, a fourth CP, etc.

In the embodiment of the application, a plurality of CPs are divided into the main and standby roles in advance according to the backup types. For example, if the backup type is a 1:1 backup type, the first CP is configured as a backup CP, the plurality of second CPs are configured as a main CP, and the first CP simultaneously provides backup services for the plurality of second CPs. And if the backup type is a 1+1 backup type, configuring the first CP as the main CP and the standby CP at the same time, and configuring the plurality of second CPs as the standby CP and the main CP. The first CP may inform that the 1:1 backup type and the 1+1 backup type are supported.

The main CP disaster backup group is configured in the main CP, the backup CP disaster backup group is configured in the backup CP, and the backup CP disaster backup groups which are mutually main and backup comprise the same at least one UP identification.

When a plurality of second CPs have faults or a link between the UPs indicated by the UP identifier in each second CP and the main CP disaster backup group has faults, the first CP locally obtains the group identifier of the disaster recovery channel group bound to the address of each second CP according to the address (specifically, IP address) of each second CP.

Further, before executing the step, the method further includes a process that the second CP and the first CP respectively receive a plurality of configuration instructions input by the user, and a process that the second CP and the first CP respectively establish the disaster recovery channel with the opposite end, configure the CP disaster recovery group locally, and bind the group identifier of the disaster recovery channel group with the group identifier of the CP disaster recovery group through the plurality of configuration instructions.

The following description will be given taking the second CP and the third CP as examples:

the second CP receives a first configuration instruction input by a user, the first configuration instruction comprises a first group of parameters for configuring the disaster recovery channel group, the first group of parameters comprises a group identifier and address parameters of the disaster recovery channel group, and the address parameters comprise an IP address of the second CP and an IP address of the first CP.

And according to the IP address of the first CP, the second CP and the first CP establish a disaster recovery channel, and the group identification of the disaster recovery channel group is bound with the established disaster recovery channel. The disaster recovery channel comprises a heartbeat channel, a plurality of data backup channels and a disaster recovery protection channel. The process of establishing the disaster recovery channel is the same as that of establishing the disaster recovery channel by the existing main CP and standby CP, and is not repeated here.

In one example, the group identifier of the disaster recovery channel group included in the first configuration instruction is a disaster recovery channel group1, and the address parameter includes an IP address of the first CP and an IP address of the second CP. And according to the address parameters, the second CP and the first CP establish a disaster recovery channel 1, wherein the address of one end of the disaster recovery channel 1 is the IP address of the second CP, and the address of the other end of the disaster recovery channel 1 is the IP address of the first CP. The disaster recovery channel 1 is bound with the disaster recovery channel group 1.

The third CP receives a first configuration instruction input by a user, wherein the first configuration instruction comprises a first group of parameters for configuring the disaster recovery channel group, the first group of parameters comprises a group identifier and address parameters of the disaster recovery channel group, and the address parameters comprise the IP address of the third CP and the IP address of the first CP.

And according to the IP address of the first CP, the third CP and the first CP establish a disaster recovery channel, and the group identification of the disaster recovery channel group is bound with the established disaster recovery channel. The disaster recovery channel comprises a heartbeat channel, a plurality of data backup channels and a disaster recovery protection channel. The process of establishing the disaster recovery channel is the same as that of establishing the disaster recovery channel by the existing main CP and standby CP, and is not repeated here.

In one example, the group identifier of the disaster recovery channel group included in the first configuration instruction is a disaster recovery channel group2, and the address parameter includes an IP address of the first CP and an IP address of the third CP. And according to the address parameters, the third CP and the first CP establish a disaster recovery channel 2, wherein the address of one end of the disaster recovery channel 2 is the IP address of the third CP, and the address of the other end of the disaster recovery channel 2 is the IP address of the first CP. The disaster recovery channel 2 is bound with the disaster recovery channel group 2.

And the second CP receives a second configuration instruction input by the user again, wherein the second configuration instruction comprises a second group of parameters for configuring the CP disaster recovery group, and the second group of parameters comprises the name, the group identifier, the role and the UP identifier to be managed of the CP disaster recovery group.

And configuring the CP disaster backup group on the second CP according to the name, the group identifier and the role of the CP disaster backup group, wherein the CP disaster backup group has the name, the group identifier and the role, and the CP disaster backup group comprises an UP identifier to be managed.

In one example, the second CP configures the main CP disaster recovery group on the second CP according to the name, group identifier, and role of the CP disaster recovery group. For example, the name of the main CP disaster recovery group is group1, and the group identification is group-id 1.

And the third CP receives a second configuration instruction input by the user again, wherein the second configuration instruction comprises a backup type and a second group of parameters for configuring the CP disaster recovery group, and the second group of parameters comprises the name, the group identifier, the role of the CP disaster recovery group and the UP identifier to be managed.

And configuring a plurality of CP disaster backup groups on a third CP according to the backup type, the name of the CP disaster backup group, the group identifier and the role, wherein the CP disaster backup group has the name, the group identifier and the role, and the CP disaster backup group comprises the UP identifier to be managed.

In an example, if the backup type is 1+1 backup type, two CP disaster recovery groups are configured on the third CP, where one CP disaster recovery group is named group2, the group identifier is group-id2, and the role is main CP disaster recovery group; the name of the other CP disaster recovery group is group3, the group identification is group-id3, and the role is the backup CP disaster recovery group.

And the second CP receives a third configuration instruction input by the user again, wherein the third configuration instruction comprises the group identifier of the disaster recovery channel group and the group identifier of the CP disaster recovery group.

And the second CP binds the group identification of the disaster recovery channel group and the group identification of the CP disaster recovery group.

In one example, the second CP binds disaster recovery group1 with the group identification group1 of the main CP disaster recovery group.

And the third CP receives a third configuration instruction input by the user again, wherein the third configuration instruction comprises the group identifier of the disaster recovery channel group and the group identifier of the CP disaster recovery group.

And the third CP binds the group identification of the disaster recovery channel group and the group identifications of the plurality of created CP disaster recovery groups.

In one example, if the backup type is 1+1 backup type, the third CP binds the disaster tolerant channel group2 with the group identifier group2 of the main CP disaster-prepared group and the group identifier group3 of the backup CP disaster-prepared group, respectively.

The following description will be made by taking the first CP as an example:

the first CP receives a plurality of first configuration instructions input by a user, each first configuration instruction comprises a first group of parameters for configuring the disaster recovery channel group, each first group of parameters comprises a group identifier and an address parameter of the disaster recovery channel group, and each address parameter comprises an IP address of the second CP and an IP address of the first CP.

And according to the IP address of the second CP, the first CP and the second CP establish a disaster recovery channel, and the group identification of the disaster recovery channel group is bound with the established disaster recovery channel. The disaster recovery channel comprises a heartbeat channel, a plurality of data backup channels and a disaster recovery protection channel. The process of establishing the disaster recovery channel is the same as that of establishing the disaster recovery channel by the existing main CP and standby CP, and is not repeated here.

In one example, the group identifier of the disaster recovery channel group included in the first configuration instruction is a disaster recovery channel group1, and the address parameter includes an IP address of the first CP and an IP address of the second CP. And according to the address parameters, the first CP and the second CP establish a disaster recovery channel 1, wherein the address of one end of the disaster recovery channel 1 is the IP address of the first CP, and the address of the other end of the disaster recovery channel 1 is the IP address of the second CP. The disaster recovery channel 1 is bound with the disaster recovery channel group 1.

In another example, the group identifier of the disaster recovery channel group included in the first configuration instruction is a disaster recovery channel group2, and the address parameter includes an IP address of the first CP and an IP address of the third CP. According to the address parameters, the first CP and the third CP establish a disaster recovery channel 2, where an address at one end of the disaster recovery channel 2 is an IP address of the first CP, and an address at the other end of the disaster recovery channel 2 is an IP address of a third CP (the third CP is one of the plurality of second CPs, and is described here as an example of the third CP). The disaster recovery channel 2 is bound with the disaster recovery channel group 2.

And the first CP receives a plurality of second configuration instructions input by the user again, each second configuration instruction comprises a backup type and a second group of parameters for configuring the CP disaster recovery group, and each second group of parameters comprises the name, the group identifier, the role and the UP identifier to be managed of the CP disaster recovery group.

And configuring a plurality of CP disaster recovery groups on the first CP according to the backup type, the name of the CP disaster recovery group, the group identifier and the role, wherein each CP disaster recovery group has the name, the group identifier, the role and the provided backup type and comprises an UP identifier to be managed.

The backup types include a 1:1 backup type and a 1+1 backup type.

In one example, if the backup type is a 1:1 backup type, a backup CP backup group is configured on the first CP, the name of the backup CP backup group is group1, and the group identifier is group-id 1.

In another example, if the backup type is 1+1 backup type, two CP disaster recovery groups are configured on the first CP, where one CP disaster recovery group is named group2, the group identifier is group-id2, and the role is a backup CP disaster recovery group; the name of the other CP disaster recovery group is group3, the group identification is group-id3, and the role is the main CP disaster recovery group.

And the first CP receives a plurality of third configuration instructions input by the user again, wherein each third configuration instruction comprises the group identification of the disaster recovery channel group and the group identification of at least one CP disaster recovery group.

And the first CP binds the group identification of the disaster recovery channel group with the group identification of at least one CP disaster recovery group.

In one example, if the backup type is a 1:1 backup type, the first CP binds the disaster recovery group1 with the group identification group1 of the backup CP disaster recovery group.

In another example, if the backup type is 1+1 backup type, the first CP binds the disaster recovery channel group2 with the group identifier group2 of the backup CP disaster group and the group identifier group3 of the main CP disaster group, respectively.

It should be noted that, according to the description of the foregoing embodiment, after the first CP, the second CP, and the third CP locally bind the group identifier of the configured disaster recovery channel group and the group identifier of the CP disaster backup group, respectively, the UP indicated by the UP identifier in the CP disaster backup group establishes a CUSP channel with the CP where the main CP disaster backup group is located. The main and standby CP disaster backup groups inform the UP of the main and standby roles of the main and standby CP disaster backup groups through the CUSP channel. For UP, the CP in which the main CP disaster recovery group is located is the main CP, and the CP in which the backup CP disaster recovery group is located is the backup CP. Subsequently, the UP and the main CP perform interaction of the protocol packet and the service packet.

After the protocol message sent by the user terminal is sent to the main CP through UP, the main CP interacts with the AAA server and the DHCP server to complete the user authentication and the application of the IP address, and the main CP generates a user table entry. The main CP sends down the user list item to UP through CUSP channel. Subsequently, the UP can forward the service message according to the user table entry. The UP reports the statistical information of the user flow to the main CP at regular time through the CUSP channel so that the main CP sends the statistical information to the AAA server, and the AAA server carries out charging processing according to the statistical information.

The process from the UP and the main CP establishing the CUSP channel to the main CP sending the statistical information to the AAA server is the same as the existing process, and is only described briefly here.

Further, before executing the step, the method further includes a process that the second CP periodically sends a heartbeat message to the first CP, and the first CP determines whether to execute the active-standby switching or not through the heartbeat message.

Two second CPs (i.e., second CP, third CP) are taken as an example for explanation:

the second CP generates a first heartbeat message, wherein the first heartbeat message comprises the working state of the second CP or the first link failure rate between the UP indicated by the UP identifier in the main CP disaster backup group and the second CP. Similarly, the third CP also generates a first heartbeat packet, where the first heartbeat packet includes a working state of the third CP or a first link failure rate between the third CP and the UP indicated by the UP identifier in the main CP disaster backup group.

And sending heartbeat messages to the first CP by the second CP and the third CP through the heartbeat channel.

And the first CP receives the heartbeat message through the heartbeat channel and acquires the working state of the CP or the failure rate of the first link from the heartbeat message.

In one implementation, if the working state of the CP is the unavailable state, the first CP determines that the second CP and the third CP are in failure, and performs the step.

In another implementation manner, the first CP obtains a second link failure rate between itself and the UP indicated by the UP identifier in the backup CP disaster backup group. If the first link failure rate is not less than a preset failure threshold (e.g., 80%) and the second link failure rate is less than the failure threshold, the first CP determines that the second CP and the third CP are failed, and performs this step.

Step 120, determining the backup type provided for each second CP and the group identifier of the backup CP disaster recovery group bound to the group identifier of the disaster recovery group according to the group identifier of the disaster recovery group.

Specifically, according to the description in step 110, after the first CP obtains the group identifier of the disaster recovery path group bound to the address of each second CP, the backup type provided by the first CP for each second CP and the group identifier of the backup CP disaster backup group bound to the group identifier of the disaster recovery path group are determined according to the group identifier of the disaster recovery path group.

Further, in an example, the group of the disaster tolerant channel group acquired by the first CP is identified as a disaster tolerant channel group 1. According to the disaster recovery channel group1, the first CP determines that the backup type provided by the first CP is a 1:1 backup type, and the group identifier of the backup CP disaster recovery group is group 1.

In another example, the group of the disaster tolerant channel group acquired by the first CP is identified as disaster tolerant channel group 2. According to the disaster recovery channel group2, the first CP determines that the backup type provided by the first CP for the third CP is 1+1 backup type, and the group identifier of the backup CP disaster backup group is group 2.

Step 130, taking over the backup CP disaster backup group corresponding to the group identifier of the backup CP disaster backup group according to the backup type, and providing service for the UP corresponding to at least one UP identifier included in the backup CP disaster backup group.

Specifically, according to the description in step 120, after determining the backup type provided for each second CP and the group identifier of the backup CP disaster backup group, the first CP takes over the backup CP disaster backup group corresponding to the group identifier of the backup CP disaster backup group according to the backup type, and provides service for the UP corresponding to at least one UP identifier included in the backup CP disaster backup group.

It can be understood that the first CP serves as a backup CP of the second CP, and the locally configured backup CP disaster backup group1 is the same as the main CP disaster backup group1 configured on the second CP, and both include the same UP flag.

Similarly, the first CP serves as a backup CP of the third CP, and the locally configured backup CP disaster backup group2 is the same as the main CP disaster backup group2 configured on the third CP, and both include the same UP identifier.

Therefore, the first CP can provide backup service for a plurality of failed main CPs at the same time, and can quickly take over the UP and the user service borne by the UP in the process of main-standby switching.

Therefore, by applying the backup implementation method provided by the present application, when multiple second CPs fail or a link between the UP indicated by the UP identifier in each second CP and the main CP disaster recovery group fails, the first CP obtains the group identifier of the disaster recovery channel group bound to the address of each second CP according to the address of each second CP; according to the group identification of the disaster tolerant channel group, the first CP determines the backup type provided for each second CP and the backup CP disaster backup group bound with the group identification of the disaster tolerant channel group; and according to the backup type, the first CP takes over the backup CP disaster recovery group and provides service for the UP corresponding to at least one UP identifier included in the backup CP disaster recovery group.

Another implementation method of backup provided in the embodiments of the present application is described in detail below. Referring to fig. 2, fig. 2 is a flowchart of another implementation method of backup according to an embodiment of the present application. The method is applied to the first CP. The implementation method of the backup provided by the embodiment of the application may include the following steps.

Step 210, generating a heartbeat packet, where the heartbeat packet includes a working state of the first CP or a first link failure rate between the first CP and the UP indicated by the UP identifier in the main CP disaster backup group.

Step 220, sending the heartbeat packet to a second CP through a heartbeat channel, so that the second CP takes over the backup CP disaster backup group when determining that the first CP has a failure or a link failure between UPs indicated by the UP identifier in the backup CP disaster backup group is determined according to the working state or the first link failure rate, and provides a service for a UP corresponding to at least one UP identifier included in the backup CP disaster backup group.

Optionally, in this embodiment of the present application, the method further includes a process that the first CP receives a plurality of configuration instructions input by a user, and a process that the first CP establishes the disaster recovery channel with the opposite end, configures the CP disaster recovery group locally, and binds the group identifier of the disaster recovery channel group with the group identifier of the CP disaster recovery group through the plurality of configuration instructions.

It should be noted that, in the foregoing embodiment, the process of receiving the configuration instruction of the second CP and the third CP serving as the main CP and performing local configuration according to the configuration instruction, and the process of interacting the heartbeat message with the first CP serving as the standby CP have been received in detail, and will not be repeated here.

The following describes in detail a method for implementing backup provided in the embodiments of the present application. Referring to fig. 3 and 4, fig. 3 is a schematic diagram of N:1 backup networking when multiple primary CPs provided by the embodiment of the present application normally operate, and fig. 4 is a schematic diagram of N:1 backup networking when multiple primary CPs provided by the embodiment of the present application fail.

The following description will be given taking an example in which three CPs are included in fig. 3 and 4.
