[0002] The present application claims priority from the Chinese patent application No. 202410863862.0 filed on June 29, 2024, and entitled "Message processing method, server and storage medium", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application belongs to the technical field of data processing, and particularly relates to a message processing method, a server and a storage medium. BACKGROUND

[0004] A virtual broadband remote access server (vBRAS) device based on separation of forwarding and control includes a vBRAS control plane (vBRAS-CP) and a vBRAS user plane (vBRAS-UP). The vBRAS-CP is responsible for access control and policy of a user, and the vBRAS-UP is responsible for completing forwarding plane functions such as user service traffic forwarding and traffic control. The CP device and the UP device communicate through a control plane interface protocol.

[0005] In the related art, in order to avoid UP device failure, pool backup is performed on the UP device by the CP device. When the UP device cannot communicate with the CP device, the CP device switches the related service of the UP device to another UP device, that is, the user is notified to perform pool backup protection switching to another UP device. However, since the original UP device can still normally forward service traffic, the user constantly performs Media Access Control (MAC) drift between the two UPs, which affects normal service forwarding of the user.

[0019] The packet processing method, server and storage medium provided by the embodiments of the present application will be described in detail below in combination with FIGS. 1-4 through embodiments and application scenarios.

[0020] FIG. 1 is a flowchart of a packet processing method provided by an embodiment of the present application. As shown in FIG. 1, the packet processing method can include the contents shown in steps 101-102.

[0021] In S101, a to-be-sent packet is obtained, and the to-be-sent packet is a packet to be sent to a user equipment.

[0022] It should be noted that the to-be-sent packet can be a packet actively sent to the user equipment, or a response packet based on the packet sent by the user equipment for feedback. The packet type can be determined according to the packet format, or it can be determined by other means, and the actual application is subject to the present embodiment.

[0023] In S102, in a case where it is determined that the virtual broadband remote access server user plane vBRAS-UP device is an island device and the message type of the to-be-sent message is an active sending message type, the to-be-sent message is suppressed from being sent to the user equipment.

[0024] The message type can include an active sending message type and a response message type.

[0025] It should be noted that the suppression of the to-be-sent message from being sent to the user equipment means that the to-be-sent message is not sent to the user equipment after being obtained, and the to-be-sent message can be discarded.

[0026] In the embodiments of the present application, the to-be-sent message is first obtained, and the to-be-sent message is a message to be sent to the user equipment. Then, in a case where it is determined that the virtual broadband remote access server user plane vBRAS-UP device is an island device and the message type of the to-be-sent message is an active sending message type, the to-be-sent message is suppressed from being sent to the user equipment. In the embodiments of the present application, the active sending message is suppressed from being sent to the user equipment after it is determined that the vBRAS-UP device is an island device. The active sending message can be interacted with the user equipment without being sent to the user equipment under the premise of normal maintenance of user data forwarding. Thus, the normal sending of user data can be ensured, and the situation that the user constantly performs MAC drift between two vBRAS-UP devices can be avoided.

[0027] In a possible implementation of the present application, after the to-be-sent message is obtained, the message processing method can further include: detecting the state of the vBRAS-UP device; and in a case where the state of the vBRAS-UP device is an island state, detecting the message type of the to-be-sent message, the message type including an active sending message type and a response message type.

[0028] The active sending message type refers to a message that is actively sent by the vBRAS-UP device to the user equipment, and the response message type refers to a message that is generated in response to a user message sent by the user equipment.

[0029] For example, an address resolution protocol (ARP) request is an active sending message type, and an ARP response message is a response message type.

[0030] In the embodiment, in the case of obtaining a to-be-sent packet, the state of the vBRAS-UP device is first detected to determine whether the state of the vBRAS-UP device is an island state, and in the case of detecting that the state of the vBRAS-UP device is the island state, it is further detected whether the packet type of the to-be-sent packet is the active sending packet type or the response packet type, and in the case of the state of the vBRAS-UP device being the island state and the packet type of the to-be-sent packet being the active sending packet type, the sending of the to-be-sent packet is inhibited. Since the vBRAS-UP device determined as the island device does not actively send packets to the user equipment, after the user equipment accesses other vBRAS-UP devices, the user equipment can directly establish a connection with the other vBRAS-UP devices and send packets to the other vBRAS-UP devices, and thus the MAC address drift does not occur, and the normal service forwarding of the user equipment is ensured.

[0031] That is, in the case of obtaining a to-be-sent packet, the state of the vBRAS-UP device is first detected, if the vBRAS-UP device is in a normal state, the obtained to-be-sent packet is directly sent to the user equipment, and it is not necessary to detect the packet type of the to-be-sent packet, that is, the step of detecting the packet type of the to-be-sent packet can be omitted; if the vBRAS-UP device is in an island state, the packet type of the to-be-sent packet is further detected, if the packet type of the to-be-sent packet is a response packet, the to-be-sent packet can be directly sent to the user equipment, and if the packet type of the to-be-sent packet is an active sending packet type, the sending of the to-be-sent packet is inhibited, and thus the MAC address drift does not occur after the user equipment accesses other vBRAS-UP devices, and the service of the user equipment can be normally forwarded.

[0032] In a possible implementation of the present application, after obtaining a to-be-sent packet, the packet processing method can further include: detecting the packet type of the to-be-sent packet, the packet type including an active sending packet type and a response packet type; and in the case of the packet type being the active sending packet type, detecting the state of the vBRAS-UP device.

[0033] That is, in addition to the above-mentioned embodiment of first detecting the state of the vBRAS-UP device and then detecting the packet type of the to-be-sent packet, the packet type of the to-be-sent packet can be first detected, and in the case of the packet type of the to-be-sent packet being the active sending packet type, the state of the vBRAS-UP device is further detected, and in the case of the packet type of the to-be-sent packet being the active sending packet type and the state of the vBRAS-UP device being the island state, the sending of the to-be-sent packet is inhibited. The normal service forwarding of the user equipment can be ensured, and the MAC address drift does not occur.

[0034] That is, in the case of obtaining a to-be-sent packet, the packet type of the to-be-sent packet can be detected first, if the packet type is a response type, the obtained to-be-detected packet is directly sent to the user equipment, without detecting the state of the vBRAS-UP equipment, that is, the step of detecting the state of the vBRAS-UP equipment can be omitted; if the packet type is an active sending packet type, the state of the vBRAS-UP equipment is further detected, if the state of the vBRAS-UP equipment is a normal state, the to-be-sent packet can be directly sent to the user equipment, if the state of the vBRAS-UP equipment is an island state, the to-be-sent packet is inhibited from being sent, so as to ensure the normal service forwarding of the user equipment and avoid MAC address drift.

[0035] In other embodiments, other methods can also be used, for example, in order to quickly determine whether the obtained to-be-sent packet can be sent to the user equipment, the state of the vBRAS-UP equipment and the packet type of the to-be-sent packet can be detected at the same time, as long as it is determined whether the obtained to-be-sent packet can be sent to the user equipment, the present embodiment is not limited, and the actual application is used as the criterion.

[0036] In a possible embodiment of the present application, after detecting the state of the vBRAS-UP equipment, the packet processing method can further include: in the case where the state of the vBRAS-UP equipment is a normal state, sending the to-be-sent packet to the user equipment.

[0037] That is, in the case where the state of the vBRAS-UP equipment is a normal state, it means that the vBRAS-UP equipment is normal, at this time the to-be-sent packet can be directly sent to the user equipment. The normal communication between the vBRAS-UP equipment and the user equipment is ensured.

[0038] In a possible embodiment of the present application, after detecting the packet type of the to-be-sent packet, the packet processing method can further include: in the case where the packet type is a response packet type, sending the to-be-sent packet to the user equipment, the to-be-sent packet being a packet generated in response to a user packet sent by the user equipment.

[0039] In the present embodiment, if the packet type is detected as a response packet type, the to-be-sent packet can be directly sent to the user equipment. That is, in the case where the vBRAS-UP equipment is an island device, the present embodiment only inhibits the packet actively sent to the user equipment, and does not inhibit the packet generated in response to the user packet sent by the user equipment. In the case where the vBRAS-UP equipment is an island device but the user equipment is not accessed to other vBRAS-UP equipment, the vBRAS-UP equipment can normally reply to the user equipment, maintain the normal interaction with the user equipment, and avoid the situation where the user equipment cannot work.

[0040] In a possible implementation of the present application, detecting the state of the vBRAS-UP device can include: detecting a communication state between the vBRAS-UP device and a virtual broadband remote access server control plane vBRAS-CP device; and determining that the state of the vBRAS-UP device is an island state in a case where the communication state is abnormal.

[0041] The number of vBRAS-CP devices can be one, two or more, that is, to avoid the situation that the vBRAS-CP device is damaged and the vBRAS-UP device becomes an island, a networking mode of two vBRAS-CP devices or a networking mode of multiple vBRAS-CP devices can be set, that is, a networking mode of connecting the vBRAS-UP device to two vBRAS-CP devices or multiple vBRAS-CP devices. The number of vBRAS-CP devices is not limited in the embodiment, and is subject to actual application.

[0042] In the embodiment, the vBRAS-UP device becomes an island device in a case where communication between the vBRAS-UP device and the vBRAS-CP device is abnormal. That is, in a case where the vBRAS-CP device cannot receive a packet of the vBRAS-UP device, it is determined that the vBRAS-UP device is abnormal, and at this time, the vBRAS-CP device transfers a user device connected to the vBRAS-UP device to another vBRAS-UP device to ensure normal service forwarding of the user device.

[0043] In a possible implementation of the present application, the communication state abnormality includes at least one of the following: a link abnormality between the vBRAS-UP device and the vBRAS-CP device; and the vBRAS-UP device not receiving a keep-alive packet of the vBRAS-CP device within a preset time period.

[0044] That is, the reason for causing the vBRAS-UP device to become an island device can be a communication state exception, which can be a link exception between the vBRAS-UP device and the vBRAS-CP device, that is, a connection interruption between the vBRAS-UP device and the vBRAS-CP device, the vBRAS-CP device cannot receive the message sent by the vBRAS-UP device, and cannot send the message to the vBRAS-UP device. In this case, the vBRAS-CP device is in a normal state, in order to ensure the normal work of the user device, the vBRAS-UP device no longer actively sends the message to the user device, the vBRAS-CP device can transfer the user device connected with the vBRAS-UP device to other vBRAS-UP device, the user device and the other vBRAS-UP device perform forwarding and protocol interaction, and the original island vBRAS-UP device will not make the user device re-cut back to the island vBRAS-UP device because it will not actively send the message.

[0045] The communication state exception can also be an exception of the vBRAS-CP device. Since the vBRAS-CP device fails, the vBRAS-CP device cannot notify the user device connected with the vBRAS-UP device to perform protection switching, at this time, the vBRAS-UP device in the island state continues to maintain the connection with the user device, and keeps the normal forwarding of the service of the user device that has been online, that is, the vBRAS-UP device can respond to the user message sent by the user device.

[0046] That is, in the case of obtaining the to-be-sent message, the state of the vBRAS-UP device can be determined based on the communication state between the vBRAS-UP device and the vBRAS-CP device, in the case that the communication state between the vBRAS-UP device and the vBRAS-CP device is a normal state, it is indicated that the state of the vBRAS-UP device is a normal state, and in the case of a communication state exception, it is indicated that the state of the vBRAS-UP device is an island state.

[0047] In a possible implementation of the present application, detecting the state of the vBRAS-UP device can include: querying whether the vBRAS-UP device exists a state mark; in the case that the state mark is an island state mark, determining that the vBRAS-UP device is an island device.

[0048] In the embodiment, in addition to determining whether the vBRAS-UP device is an island device by detecting the state of the vBRAS-UP device in the above embodiment, whether the vBRAS-UP device is an island device can also be determined by querying whether the vBRAS-UP device has a state mark, that is, when there is a state mark that is an island state mark, it is determined that the vBRAS-UP device is an island device. That is, after the vBRAS-UP device becomes an island device, the vBRAS-UP device can be marked with an island state mark to indicate that the state of the vBRAS-UP device is an island state, thereby inhibiting the active sending of messages to the user device.

[0049] In an example, the vBRAS-UP device can be marked with an island state mark in response to the state of the vBRAS-UP device being an island state.

[0050] In the embodiment, after detecting that the state of the vBRAS-UP device is an island state, the vBRAS-UP device is marked with an island state mark to facilitate subsequent determination of whether the vBRAS-UP device is an island device, that is, in addition to determining the communication state between the vBRAS-UP device and the vBRAS-CP device as provided in the above embodiment, the state of the vBRAS-UP device can also be determined by querying the state mark of the vBRAS-UP device.

[0051] That is, when the to-be-sent message is obtained, the vBRAS-UP device can be first detected to determine whether it is an island device, that is, the vBRAS-UP device can be determined to be an island device by determining the communication state between the vBRAS-UP device and the vBRAS-CP device, at which time the sending of the to-be-sent message to the user device needs to be inhibited, and in this case, the state of the vBRAS-UP device is not marked.

[0052] The vBRAS-UP device can also be determined to be an island device first, for example, the state of the vBRAS-UP device can be determined to be an island state by the communication state between the BRAS-UP device and the vBRAS-CP device, at which time the vBRAS-UP device is marked with an island state mark, and when the to-be-sent message is obtained, the state mark is queried to be an island state mark, and then the sending of the to-be-sent message to the user device is inhibited.

[0053] Further, in a case that the to-be-sent message is acquired, whether the vBRAS-UP device is an island device can be detected, for example, a state of the vBRAS-UP device can be determined to be an island state through a communication state between the BRAS-UP device and the vBRAS-CP device, at this time, the vBRAS-UP device is marked as an island state, so that in a subsequent determination of whether the vBRAS-UP device is an island device, the state of the vBRAS-UP device can be inquired to determine, and sending the to-be-sent message to the user device is inhibited.

[0054] In a possible implementation of the present application, after the vBRAS-UP device is marked as an island state, the message processing method can further include: in a case that a keep-alive message of the vBRAS-CP device is received, canceling the island state marking of the vBRAS-UP device.

[0055] The keep-alive message of the vBRAS-CP device indicates that the vBRAS-CP device is in a normal state, and a link between the vBRAS-UP device and the vBRAS-CP device is also normal, at this time, the vBRAS-UP device is no longer an island device, and the island state marking of the vBRAS-UP device can be canceled, so that the vBRAS-UP device can normally send the to-be-sent message of the active sending message type to the user device when the to-be-sent message is received. At this time, the vBRAS-CP device can select to migrate the user device back to the original vBRAS-UP device or keep in other vBRAS-UP devices according to the original vBRAS-UP device and other vBRAS-UP devices, and the actual application is used as the criterion, and the present embodiment is not limited.

[0056] In a possible implementation of the present application, after the sending of the to-be-sent message to the user device is inhibited, the message processing method can further include: in a case that the vBRAS-UP device recovers from the island device to the normal device and the to-be-sent message is acquired again, sending the to-be-sent message to the user device.

[0057] That is, after the vBRAS-UP device recovers to the normal state, the to-be-sent message is received again, and whether the to-be-sent message is of the active sending message type or the response message type does not need to be distinguished, and the to-be-sent message can be directly sent to the user device without inhibition. That is, the normal communication with the user device is maintained.

[0058] In an embodiment of the present application, as shown in FIG. 2, the CP device includes CP1 and CP2, and the CP1 and the CP2 are hot backup to each other; the UP device includes UP1 and UP2, and the UP1 and the UP2 are pool backup to each other; the user device is connected to the UP1 and the UP2, and the UP1 and the UP2 are connected to the CP1 and the CP2 respectively.

[0059] In the case that both CP devices are normal and the island is caused by link failure between UP and CP, the link connection between UP1 and CP1 and CP2 is disconnected, UP1 becomes an island device, at this time, CP1 and CP2 cannot keep alive with UP1, after the keep-alive time arrives, CP1 and CP2 notify the user device to switch traffic to UP2 device. After UP1 becomes an island, UP1 device sets an island state flag, and actively sends a message for suppression, if no user message sent by the user device is received, no protocol message is actively sent. The user device migrates to UP2 device based on the notification of the CP device, and establishes a connection with UP2 device, the user device MAC address is learned to UP2 device, and service traffic is forwarded from UP2 device. Since the user device service has been cut from UP1, no user protocol message is sent to UP1 device, UP1 device no longer actively sends a protocol message to the user device, and MAC address drift is not caused, that is, the user device does not perform a link establishment action with UP1, and user traffic can be maintained stable forwarding in UP2 device.

[0060] In the case that both CP devices are abnormal and the island is caused by abnormal CP devices, CP1 and CP2 devices are abnormal, UP1 cannot be connected with CP1 and CP2, and UP1 becomes an island device. After UP1 becomes an island, UP1 device sets an island state flag, and actively sends a message for suppression, if no user message sent by the user device is received, no protocol message is actively sent. At this time, since the CP device is faulty, the CP device cannot notify the user device to switch service, the user device service continues to maintain connection with UP1, and UP1 receives user protocol and keep-alive messages, and responds to the user protocol and keep-alive messages according to the island setting. Since the user device continues to interact with UP1 device, the user device MAC address is learned on UP1 device, and service traffic continues to maintain forwarding on UP1 device, and since the CP cannot respond, new user service cannot be online, and old users will perform service forwarding based on the user forwarding table saved on the existing UP1.

[0061] The embodiment of the application further provides a message processing method, applied to a vBRAS-CP device, and including: in the case that a first vBRAS-UP device does not send a keep-alive message to the vBRAS-CP device within a preset time period, switching a user device connected with the first vBRAS-UP device to a second vBRAS-UP device.

[0062] That is, after the first vBRAS-UP device becomes an island, the vBRAS-CP device migrates the user device connected with the first vBRAS-UP device to the second vBRAS-UP device, to ensure normal service forwarding of the user device.

[0063] In a possible implementation of the present application, in the case that the first vBRAS-UP device receives the keep-alive packet, the user device is switched back to the first vBRAS-UP device or kept connected to the second vBRAS-UP device according to the first vBRAS-UP device and the second vBRAS-UP device.

[0064] That is, in the case that the vBRAS-UP device is no longer an island device, the vBRAS-CP device can select to migrate the user device back to the original vBRAS-UP device or keep it in the other vBRAS-UP device according to the original vBRAS-UP device and the other vBRAS-UP device, and the actual application is subject to the actual application, which is not limited in the present embodiment.

[0065] The present application also provides a packet processing method applied to a user device, comprising: in the case that a migration notification of a vBRAS-CP device is received, disconnecting from a first vBRAS-UP device and establishing a connection with a second vBRAS-UP device; and in the case that the migration notification of the vBRAS-CP device is not received, keeping the connection with the first vBRAS-UP device and sending packets and protocols to the first vBRAS-UP device.

[0066] That is, the user device can migrate services according to the notification of the vBRAS-CP device to ensure normal service forwarding, and if the notification is not received, the user device continues to connect with the original vBRAS-UP device and normally sends packets and protocols to the original vBRAS-UP device.

[0067] In a possible implementation of the present application, in the case that the first vBRAS-UP device becomes an island device, the response packet based on the packets and protocols of the first vBRAS-UP device is received, but the packet actively sent by the first vBRAS-UP device cannot be received. To ensure that the user device can perform normal service forwarding, the MAC drift between the two vBRAS-UP devices does not occur.

[0068] The present application suppresses the active sending behavior of the protocol packet when the vBRAS-UP device becomes an island, that is, no matter what the cause of the vBRAS-UP device island is, the network can stably forward the service traffic, and the network service damage due to MAC address drift in the related art does not occur. The present application can effectively improve the forwarding stability of the vBRAS-UP device, and when the vBRAS-CP device becomes an island, the user data forwarding can be normally maintained, which can effectively improve the stability of the network and improve the network use perception of the user.

[0069] Fig. 3 is a schematic diagram of a packet processing apparatus provided by an embodiment of the present application. As shown in Fig. 3, the packet processing apparatus can include an obtaining module 301 and a processing module 302.

[0070] The obtaining module 301 is configured to obtain a to-be-sent packet, the to-be-sent packet being a packet to be sent to a user equipment; and the processing module 302 is configured to, in a case where it is determined that a virtual broadband remote access server user plane vBRAS-UP device is an island device and a packet type of the to-be-sent packet is an active sending packet type, refrain from sending the to-be-sent packet to the user equipment.

[0071] In an embodiment of the present application, the obtaining module 301 first obtains a to-be-sent packet, the to-be-sent packet being a packet to be sent to a user equipment, and then the processing module 302, in a case where it is determined that a virtual broadband remote access server user plane vBRAS-UP device is an island device and a packet type of the to-be-sent packet is an active sending packet type, refrains from sending the to-be-sent packet to the user equipment. In the embodiment of the present application, after it is determined that the vBRAS-UP device is an island device, the active sending packet is refrained from being sent to the user equipment, which can refrain from actively interacting with the user equipment on the premise of normally maintaining user data forwarding, thereby ensuring normal sending of user data and avoiding the situation that the user constantly performs MAC drift between two vBRAS-UP devices.

[0072] In a possible implementation of the present application, the packet processing apparatus can further include a first detection module and a second detection module.

[0073] The first detection module is configured to detect a state of the vBRAS-UP device; and the second detection module is configured to, in a case where the state of the vBRAS-UP device is an island state, detect a packet type of the to-be-sent packet, the packet type including an active sending packet type and a response packet type.

[0074] In a possible implementation of the present application, the packet processing apparatus can further include a third detection module and a fourth detection module.

[0075] The third detection module is configured to detect a packet type of the to-be-sent packet, the packet type including an active sending packet type and a response packet type; and the fourth detection module is configured to, in a case where the packet type is the active sending packet type, detect a state of the vBRAS-UP device.

[0076] In a possible implementation of the present application, the packet processing apparatus can further include a first sending module.

[0077] The first sending module is configured to send the to-be-sent packet to the user equipment in the case that the state of the vBRAS-UP device is normal.

[0078] In one possible implementation of the present application, the packet processing apparatus can further include a second sending module.

[0079] The second sending module is configured to send the to-be-sent packet to the user equipment in the case of the packet type, the to-be-sent packet being a packet generated in response to a user packet sent by the user equipment.
