BRAS (Broadband Remote Access Server, Broadband Remote Access Server) uses SDN (Software Defined Network) to make hardware functions software-based, and realize the separation of forwarding and control planes, combined with NFV network function virtualization technology. vBRAS is a virtualized BRAS, which is deployed on a virtual machine or in the cloud to enhance performance and scalability. For the case where the control plane network elements are deployed in backup mode, when the active CP fails, the active/standby switchover protection mechanism is triggered. However, the master-standby switchover process takes a certain amount of time, generally ranging from a few minutes to more than ten minutes. During this time, new users cannot go online, which affects user experience. Aiming at this problem, a user online method of the disclosed vBRAS is proposed.

Referring to FIG. 1 , a vBRAS user online method according to an embodiment of the present disclosure, the vBRAS includes a control plane network element CP and a forwarding plane network element UP, and the CP includes an active CP and a standby CP.

In this example implementation manner, the control plane network element may be used to perform user control management, user access control, user authentication, authorization and charging, address management, and the like. The forwarding plane network element can be used for forwarding functions such as traffic forwarding, quality of service (Quality of Service, QoS), traffic statistics, etc., and can also be used for routing protocols and other functions. The control plane can use virtualization technology and run on a series of servers, and the network elements of the forwarding plane can be implemented on hardware devices or by using virtualization technology, which is not limited in this example.

The disclosed method includes the following step S110, and the disclosed method can be applied to the active-standby switchover phase of the vBRAS.

Step S110, when the active CP fails, the forwarding plane network element sends the second user online message to the standby CP, so that the standby CP processes the second user online message; the second user online message is not responded to by the active CP. The user online message, the first user online message is a message sent to the active CP in response to the access forwarding plane network element of the user equipment.

In this exemplary embodiment, the first user online message refers to a message sent by the forwarding plane network element in the vBRAS to the active CP when a user equipment accesses the network. The first user online message may include address information, account information, or identification information of the user equipment, and may also include service information accessed by the user equipment, which is not limited in this example. The second user online message refers to the first user online message that the active CP does not respond to. For example, a specific tag can be added to the first user online message to form the second user online message. For example, the Add identification information, etc. to the header of the message.

In this exemplary embodiment, the first user's online message can be based on PPPoE (Point to Point Protocol over Ethernet, Ethernet bearer point-to-point connection protocol), can also be based on the dynamic host configuration protocol IPoE, and can also be based on other protocol types, This example does not limit this. The second user online message may have the same protocol type as the first user online message.

In this example implementation manner, when the UP does not receive a response message from the active CP within a preset time, it may consider that the active CP is faulty.

When the active CP fails, it will cause the active CP to disconnect from the network element on the forwarding plane. In this case, an active/standby switchover is required. However, it is necessary to wait for the heartbeat detection result between the active CP and the standby CP before the active/standby switchover, that is, the real active/standby switchover process will not be triggered until the heartbeat detection is completed and the active CP is judged to be faulty. During the heartbeat detection and determination process, the user cannot go online. In the vBRAS user online method provided by the exemplary implementation of the present disclosure, in the case of failure of the active CP, the second user online message is sent to the standby CP, so that the standby CP handles the first user that the active CP does not respond to. The online message avoids the problem that new users cannot go online during the active-standby switchover process, and improves user experience without affecting network reliability. On the other hand, the function of the control plane is strengthened, the reliability of the control plane is increased, and the active/standby switching of the control plane without user awareness is realized.

The present disclosure is illustrated in more detail below in some embodiments.

In some embodiments, the first user online message includes a flag bit, and the method further includes:

The forwarding plane network element adds a target mark to the mark bit, and generates a second user online message.

In this example embodiment, the flag bit can be pre-configured in the first user online message. Under normal conditions, the flag bit is "0"; when the active CP fails, the flag bit is "1", that is, a received the second user online message. The target mark can be 1 or other forms, for example, a mark character or a multi-bit number (such as 010, etc.), which is not limited in this example.

For example, for a PPPOE user to go online, in the TAG_Type field (16bit) in the PADI message, the first bit can be selected as the tag bit. When the target tag is 1, it represents the second user's online message, and when it is 0, it represents In a normal situation, that is, the first user sends an uplink packet. For the IPOE user to go online, in the DHCP Discover message, the last bit of the Flags field (16bit) in the message can be selected as the flag bit. When the flag is 1, it represents the second user online message, and when it is 0 Represents a normal situation, that is, an uplink packet of the first user.

In some embodiments, before sending the second user online message to the standby CP, the method further includes:

The forwarding plane network element sends the first user online message to the active CP.

In this example implementation manner, in response to a user equipment online operation, a first user online message may be sent to the active CP. The first user online message may include basic information of the user equipment to be online, for example, address information, account information, identification information, etc. of the user equipment to be online, which is not limited in this example.

When the network element on the forwarding plane does not receive the first response message from the active CP within the preset time, it is determined that the active CP is faulty.

In this exemplary embodiment, the first response message is a response message of the active CP to the online message of the first user. The preset time can be determined based on an existing protocol or communication standard, or can be configured by itself, which is not limited in this example. Rapid and accurate judgment of the failure of the active CP is an important guarantee for realizing no user perception.

Referring to FIG. 2 , a vBRAS user online method according to an embodiment of the present disclosure is applied to a standby CP. The vBRAS includes a control plane network element CP and a forwarding plane network element UP, and the CP includes an active CP and a standby CP. The method may include the following steps S210 and S220.

Step S210, when the active CP fails, the standby CP receives the second user online message sent by the forwarding plane network element. The second user online message is the first user online message that the active CP has not responded to. The message sent by the network element on the forwarding plane to the active CP in response to the access of the user equipment.

Step S220, the standby CP processes the second user's online message, generates a second response message, and sends the second response message to the forwarding plane network element.

The detailed elaboration of this exemplary method has been given in the above-mentioned embodiments, and this exemplary method is only written from different sides, so details will not be repeated here.

In some embodiments, the method also includes:

Synchronizing the user information that goes online through the second user online message to the active CP, so that if the synchronization of the user information is successful, the user information is added to the user information database of the active CP.

In this example embodiment, when the standby CP finishes processing the second user's online message, it can synchronize the information of the users who have gone online through the second user's online message to the active CP, so as to inform the active CP that this part of the users is Online users whose active CP did not respond in time.

In this example embodiment, when the user information that goes online through the second user online message is successfully synchronized, it can be determined that the active CP has not failed, and the active CP will add the synchronized user information to its own user information database middle. The possible cause of this situation is that the link of the active CP is flapping. After the synchronization is successful, it means that the active CP has not sent a fault, and subsequent user online packets are still processed by the active CP. If the synchronization fails, it means that the active CP itself is faulty, and you can wait for the heartbeat detection result to determine whether to perform the active/standby switchover process.

In some embodiments, the method also includes:

The standby CP determines whether the master-standby switchover condition is currently met through the heartbeat detection between the standby CP and the active CP.

When the master-standby switchover conditions are met, the standby CP performs the master-standby switchover and notifies the forwarding plane NE.

In this example implementation, heartbeat detection can be performed between the active CP and the standby CP in real time. According to the heartbeat detection result, it can be determined whether the current master-standby switchover condition is satisfied, and when the master-standby switchover condition is met, the normal master-standby switchover process is performed. At the same time of active-standby switchover, corresponding notification messages can be sent to forwarding plane network elements, so that when subsequent users go online, forwarding plane network elements directly send the first user online report to the switched active CP (that is, the standby CP before the switchover). Just text, no need to add tag information.

As shown in Figure 3 and Figure 4, the vBRAS includes control plane network elements and forwarding plane network elements. The control plane network elements include CP1 (active CP) and CP2 (standby CP), and the forwarding plane network elements include dedicated forwarding plane network elements pUP1. ~pUP4.

The process of a user going online in a normal state is shown in Figure 3. When a user's online message arrives at the pUP, pUP1-pUP4 will all receive the user's online message, and upload the message to CP1 (primary CP). CP1 receives and processes the online message of the user, and returns a response message to pUP1~pUP4. For example, CP1 sends a response message to pUP1 to inform the user that the user is online on pUP1, and returns a response message from pUP2 to pUP4 to inform the user Not online in pUP2~pUP4.

The user online process of the present disclosure is shown in FIG. 4 , and may include the following steps S401-S407.

Step S401, the first user online message sent by pUP1-pUP4 is sent to CP1 (primary CP);

Step S402, CP1 fails to reply a response or non-response message to pUP due to failure, so that pUP1 ~ pUP4 do not receive the first response message within the preset time; pUP1 ~ pUP4 send the second response message to CP2 (standby CP). User online message.

Step S403, after receiving the second user online message, CP2 replaces the message of CP1, and replies a second response message to pUP1-pUP4. The second response message informs that the user is online on pUP1, and at the same time returns pUP2-pUP4 response messages, informing that the user is not online on pUP2-pUP4.

In step S404, CP2 synchronizes the information of users who have gone online through the second user online message to CP1, and informs that these users are online users that CP1 has not responded in time.

Step S405, when the synchronization fails and the heartbeat detection meets the master-standby switchover condition, the master-standby switchover is performed, and CP2 is switched to the active CP, and notified to all pUPs.

In the above embodiment, when the synchronization is successful, the active CP adds this part of the synchronized user information to its own user information database, indicating that the active CP is not faulty. Synchronization failure indicates that the active CP is faulty. After the active/standby switchover is completed, the subsequent first user goes online according to the normal online process.

For a detailed introduction of each step in the foregoing embodiments, reference may be made to corresponding descriptions in the foregoing embodiments, and details are not repeated here.

In the vBRAS user online method provided by this disclosure, when the active CP fails to send the first user online message sent by pUP, if the first user online message cannot be responded by CP1, it will actively send this part of the message to the standby CP. The target mark is added to the flag bit in , and the second user online message is generated to indicate that this part of the user online message is a message that CP1 has not responded to. When the standby CP receives the second user online message with the flag marked, it will temporarily replace the active CP to process this part of the user online message, and return the second response message to pUP. At the same time, the standby CP can also try to synchronize the user information that goes online through the second user online message to the active CP, so as to determine whether the active CP is sending a failure or the user fails to go online due to link vibration. Unable to go online. After the heartbeat detection and judgment are completed, the master/standby switchover can be performed normally, and subsequent user online operations can be performed according to the normal process after the switchover.

This disclosure studies the active-standby switching process of the existing vBRAS system, that is, when the active CP fails, it needs to wait for the heartbeat detection result between the active and standby CPs, and triggers the active-standby switchover after the judgment is completed, and the standby CP completes the upgrade. After the main action, it will be notified to the forwarding plane, and the forwarding plane will send subsequent user online messages to the new active CP. It was found that user-related services could not be processed during the above process of heartbeat detection, judgment, standby CP upgrade to master, and notification forwarding plane, and new users could not go online. Therefore, by adding the target flag of the flag bit in the first user online message, the standby CP can be used to temporarily replace the active CP to process the unresponsive user online message during the CP master-standby switchover, so that the user does not perceive the master CP. The standby switchover process is improved to improve user experience.
