[0020] For the convenience of description, some concepts and terms are first defined here.

[0021] Border Gateway Protocol (BGP) is a protocol used to exchange routing information between different autonomous systems (AS). It is the core routing protocol of the Internet and is responsible for determining the path of data packets between different networks.

[0022] Non-Stop Routing (NSR) is a reliability technology that ensures that when a device's primary control plane (such as the active mainboard or active route processor) fails and a primary-backup switchover (for example, active mainboard / standby mainboard switchover or route processor switchover) occurs, routing information and neighbor relationships are preserved, thereby ensuring uninterrupted packet transmission.

[0023] Iptables / netfilter is a subsystem in the Linux kernel that is used to filter and process network packets.

[0024] TCP-Repair is a technology used for Transmission Control Protocol (TCP) connections. It is mainly used to migrate or restore TCP connections without interrupting the connection.

[0025] The Remote Dictionary Server (Redis) database (DB) is an open-source in-memory data structure store that serves as a database, cache, and message broker. It supports a variety of data structures, such as strings, hashes, lists, sets, sorted sets, bitmaps, HyperLogLogs, and geospatial index radius queries.

[0026] BGP peer, also called BGP neighbor, is a logical connection relationship established between routers running BGP.

[0027] A socket is an endpoint for inter-process communication (IPC) in computer networks, used to transfer data between different devices or between different processes on the same device. It is an abstract software structure that provides a mechanism for sending and receiving data packets and is the foundation of network programming.

[0028] The socket interface is a set of programming interfaces provided by the operating system to implement network communication.

[0029] A split-brain situation occurs when, due to a network partition or communication failure, the nodes in a cluster are divided into multiple isolated subsets, each of which believes that it is the only primary cluster.

[0030] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0031] Figure 1 1 shows a schematic diagram of an example network device 100 in which embodiments of the present disclosure can be implemented. Figure 1 As shown, in some embodiments, the example network device 100 may include a control plane 110, a forwarding plane 120, and a database 130. In other embodiments, the example network device 100 may include the control plane 110 and the forwarding plane 120, and the database 130 may be implemented in another device. In some embodiments, the network device 100 may be a router device, a switch device, a firewall device, etc.

[0032] In network device 100, control plane 110 is configured to manage the device's operating status, specify data forwarding policies, and communicate with other network devices to maintain network topology and routing information. Forwarding plane 120 is configured to forward or process traffic entering and exiting the device according to the rules issued by control plane 110. Database 130 is configured to store and manage various data required for the operation of network device 100.

[0033] The control plane 110 may include a user space 111 and a kernel space 112. The user space 111 is an area in the memory space where applications run, while the kernel space 112 is an area where the system kernel and device drivers run.

[0034] User space 111 may include a command line configuration process 1111, a BGP process 1112, and a routing processing module 1113. Command line configuration process 1111 is configured to configure iptables / netfilter operation rules. For example, iptables / netfilter operation rules may include rules for forwarding and filtering packets. The BGP process is configured to exchange routing information between different autonomous systems to achieve cross-internet reachability and traffic forwarding. Routing processing module 1113 is configured to store, manage, and maintain routing information for network device 100 and provide a basis for decision-making regarding packet forwarding.

[0035] The BGP process 1112 may include an input / output (IO) thread 1114, a main thread 1115, and a transmission control protocol (TCP) queue 1116. The IO thread may be configured to receive data packets from the kernel space 112, send data packets to the kernel space 112, and process received data packets. The main thread 1115 may be configured to schedule threads in the BGP process 1112. The TCP queue 1116 may be configured to process data packets (e.g., acknowledgment (ACK) messages) replied by the kernel space 112 in a first-in, first-out (FIFO) manner, and send the data packet after the BGP process 1112 has processed the received data packet. The kernel space 112 may be configured to send and receive data packets with the forwarding plane 120 and perform iptables / netfilter operations.

[0036] It should be understood that the structure and functionality of environment 100 are described for exemplary purposes only and do not imply any limitation on the scope of the present disclosure.

[0037] As briefly mentioned above, in Border Gateway Protocol (BGP) non-interruptible routing technology, when the control plane in a network device fails or restarts, the forwarding plane continues to forward data packets normally, thereby achieving seamless routing protocol switching. For example, BGP non-interruptible routing technology can synchronize BGP session status, routing information, and other related data between the active and standby main control boards (both the active and standby main control boards are components that carry the relevant processes of the control plane in the network device), thereby ensuring that the standby main control board can immediately take over when the active main control board fails. That is, when the active main control board fails, the standby main control board can seamlessly take over the BGP session, avoiding BGP session interruption and routing oscillation, and ensuring network stability and continuity. Therefore, BGP non-interruptible routing technology can ensure that the forwarding plane is not affected when the control plane fails or is upgraded, and continues to forward data packets according to the existing routing information. In addition, using BGP non-interruptible routing technology can significantly improve network reliability and availability, and reduce network interruption time caused by router failures.

[0038] However, the BGP non-disruptive routing technology has the following shortcomings:

[0039] 1) Network equipment has many components, and active and standby control boards are required to implement active / standby switching.

[0040] 2) The heartbeat linkage between the active and standby main control boards needs to be maintained, which is a cumbersome process and prone to split-brain problems; and

[0041] 3) The network equipment system is huge, the development cycle is long, and it cannot be updated quickly.

[0042] In order to at least partially solve the above-mentioned problems and other potential problems that may exist in traditional solutions, the present disclosure provides a solution for data processing. According to various embodiments of the present disclosure, in response to a failure of the first BGP process in the control plane of a network device, the control plane stops sending and receiving data packets with the forwarding plane of the network device, and the IO thread in the first BGP process continues to process the received data packets. In response to the completion of the processing of the data packets in the IO thread, based on the BGP peer information and BGP routing information associated with the first BGP process, a second BGP process is rebuilt in the control plane, and based on the socket information of the BGP peer, the first socket interface of the BGP peer associated with the second BGP process is rebuilt. In response to the completion of the reconstruction of the second BGP process and the first socket interface, the sending and receiving of data packets between the control plane and the forwarding plane is resumed.

[0043] In this way, if the active main control board fails, a new BGP process can be started, eliminating the backup main control board and simplifying the non-disruptive routing switchover process for network devices. Furthermore, by starting a new BGP process to complete the non-disruptive routing process, split-brain issues can be avoided. This also ensures uninterrupted connectivity between BGP peers. Furthermore, this allows for rapid development and iteration of network devices, enabling flexible deployment.

[0044] Figure 2 FIG2 shows a schematic diagram of a process 200 for data processing according to some embodiments of the present disclosure. The process 200 may be implemented in the network device 110. Figure 1 The process 200 is described in detail.

[0045] At block 210, in response to a failure of the BGP process 1112 in the control plane 110, the network device 110 stops sending and receiving packets between the control plane 110 and the forwarding plane 120 of the network device 100. For discussion purposes, the BGP process herein may be referred to as a "first BGP process."

[0046] In some embodiments, the data packet may be a routing message, which transmits routing information (e.g., network topology, reachability, path attributes, etc.) between network devices (e.g., routers) to establish, update, and maintain routing tables.

[0047] First BGP process 1112 refers to the process currently established in control plane 110 of network device 110. A failure of first BGP process 1112 may be caused by a variety of factors. These factors may include, for example, configuration errors, network issues, resource exhaustion, software / hardware failures, etc. It should be understood that these factors are merely exemplary and not intended to be limiting. Network device 110 may use any suitable method to determine whether the first BGP process has failed.

[0048] In some embodiments, when the first BGP process 1112 exits due to a fault, the network device 100 may prevent the routing processing module 1113 from recording the exit status of the first BGP process 1112, thereby not performing any update operations on the routing table in the forwarding plane 120. In one example, the routing processing module 1113 may be implemented by a Routing Information Base (RIB) process. In other words, the network device 100 may make the RIB process unaware of the exit of the first BGP process 1112, thereby preventing the RIB process from performing any update operations on the routing table in the forwarding plane 120.

[0049] In some embodiments, the network device 100 may cause the IO thread 1115 to stop receiving packets sent by the kernel space 112 in the control plane 110 , and cause the kernel space 112 to stop sending packets to the forwarding plane 120 .

[0050] For example, the network device 100 may enable the TCP queue 1116 to use the TCP-repair technology of the kernel space 112 to set the socket information of the BGP peer to a fault recovery enabled state (e.g., a repair-on state), thereby enabling the IO thread 1115 to stop receiving data packets sent by the kernel space 112 in the control plane 110. The repair-on state indicates that the BGP fault recovery function is enabled.

[0051] For example, the network device 100 can use the iptables / netfilter of the kernel space 112 to lock the data packets in the input 1121 and output 1125 directions of the kernel space 112, that is, Figure 1 The transmission paths represented by arrows 140 and 150 are locked, so that the kernel space 112 stops sending data packets to the forwarding plane 120 .

[0052] At block 220 , the network device 100 causes the IO thread 1114 in the first BGP process 1112 to continue processing the received data packet.

[0053] In some embodiments, the received data packet indicates a data packet sent by kernel space 112 to IO thread 1114 via input 1121 before the first BGP process 1112 fails.

[0054] In block 230, in response to the completion of processing of the packet in IO thread 1114, network device 100 reestablishes a BGP process in the control plane based on the BGP peer information and BGP routing information associated with first BGP process 1112. For purposes of discussion, this BGP process may be referred to as a "second BGP process."

[0055] BGP peer information may include configuration parameters, operational status, and statistical data between the first BGP process and its BGP neighbors. BGP routing information is routing data used in the Border Gateway Protocol for exchange between different autonomous systems. For example, it may include destination network addresses, path attributes, and reachability information.

[0056] In some embodiments, the network device 100 may store BGP peer information, BGP routing information, and socket information in the database 130, thereby ensuring the subsequent recovery of the BGP peer information, BGP routing information, and socket information. For example, the network device 100 may store the BGP peer information, BGP routing information, and socket information in the database 130 when the first BGP process 1112 fails. For another example, the network device 100 may also store the BGP peer information, BGP routing information, and socket information in the database 130 when the first BGP process 1112 does not fail. In some embodiments, the database 130 may be a remote dictionary service database. In some embodiments, the network device 100 may store the BGP peer information and BGP routing information in the remote dictionary service database in the form of a snapshot. In some embodiments, the network device 100 may also store the socket information in the remote dictionary service database in any appropriate manner.

[0057] When it is necessary to reestablish the second BGP process, network device 100 can obtain BGP peer information and BGP routing information from database 130. In some embodiments, when reestablishing the second BGP process, network device 100 can first initiate the second BGP process. Network device 100 obtains BGP peer information and BGP routing information from database 130 and, based on the BGP peer information and BGP routing information, restores the initiated second BGP process to the state it was in before the failure of first BGP process 1112. Because the BGP peer information and BGP routing information are collected and stored specifically for first BGP process 1112, based on this pre-stored information, the newly created second BGP process can be restored to the state it was in before the failure of the first BGP process. It should be understood that when network device 100 utilizes BGP peer information and BGP routing information to restore the second BGP process, it can adopt any method known in the relevant art, and the embodiments of the present disclosure are not intended to be limiting in this regard.

[0058] At block 240, network device 100 reestablishes the socket interface of the BGP peer associated with the second BGP process based on the socket information of the BGP peer. For discussion purposes, the socket interface herein may be referred to as a "first socket interface."

[0059] In some embodiments, network device 100 may shut down a socket interface of a BGP peer associated with first BGP process 1112 in response to cessation of data packet transmission and reception between control plane 110 and forwarding plane 120, i.e., in response to a failure of first BGP process 1112. For example, the socket interface may be shut down upon exit of first BGP process 1112. For purposes of discussion, the socket interface herein may be referred to as a "second socket interface."

[0060] In some embodiments, when the network device 100 rebuilds the first socket interface, it may first establish the first socket interface. The network device 110 may obtain socket information from the database 130 and update the first socket interface based on the socket information. It should be understood that when the network device 100 uses the socket information to update the first socket interface, it may adopt any method in the relevant technology, and the embodiments of the present disclosure are not intended to limit this. Since the socket information obtained from the database is collected and stored for the BGP peer associated with the first BGP process 1112, based on the pre-stored socket information, the newly created socket interface can be updated to the state before the failure of the first BGP process.

[0061] In block 250 , in response to the completion of the reestablishment of the second BGP process and the first socket interface, the network device 100 resumes the sending and receiving of data packets between the control plane 110 and the forwarding plane 120 .

[0062] In some embodiments, when the second BGP process and the first socket interface are reestablished, the network device 100 may cause the IO thread 1114 to resume receiving data packets sent by the kernel space 112 in the control plane 110, and cause the kernel space 112 to resume sending data packets to the forwarding plane 120. In this way, the state of the BGP peer can be restored to a state where the connection has been successfully established and is in a stable communication phase.

[0063] For example, the network device 100 can use the TCP-repair technology to set the socket information of the kernel space 112 to the repair-off state, so that the IO thread 1115 can resume receiving data packets sent by the kernel space 112 in the control plane 110. The repair-off state refers to the state in which the BGP fault recovery function is disabled.

[0064] For example, the network device 100 can use the TCP queue 1116 to delete the locks of iptables / netfilter in the INPUT 1121 and OUTPUT 1125 directions, that is, Figure 1 The lock on the transmission path represented by arrows 140 and 150 in FIG. 1 can enable the kernel space 112 to resume sending data packets to the forwarding plane 120 .

[0065] In some embodiments, the network device 100 may cause the routing information base (RIB) process to determine whether the second BGP process has been updated based on the BGP routing information. If it is determined that the second BGP process has been updated, the RIB process may be caused to update the routing table of the forwarding plane; if it is determined that the second BGP process has not been updated, the RIB process may be prevented from updating the routing table.

[0066] For example, when the second BGP process is started and sends a data packet to the RIB process, the RIB process can determine whether the BGP routing information has been updated. For example, the RIB process can determine whether the BGP routing information has changed. If the BGP routing information has not changed, the RIB process can determine that the second BGP process has not been updated. Conversely, if the BGP routing information has changed, the RIB process can determine that the second BGP process has been updated. If the second BGP process has not been updated, the RIB process does not update the routing table in the forwarding plane 120, so that the forwarding plane 120 will not perceive the above-mentioned operation of the control plane 110 (i.e., rebuilding the BGP process and socket interface), thereby ensuring that traffic forwarding is not affected.

[0067] In summary, if the active MPU fails, a new BGP process can be started, eliminating the standby MPU and simplifying the non-disruptive routing switchover process for network devices. Furthermore, starting a new BGP process to complete the non-disruptive routing process avoids split-brain issues and ensures uninterrupted connectivity between BGP peers. Furthermore, this allows for rapid development and iteration of network devices, enabling flexible deployment.
