Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a hot backup processing method, apparatus, device, and machine-readable storage medium. Background Art

[0002] With the rapid development of the internet and the digital transformation of various industries, the number of services carried by networks is increasing, and their importance is growing. Ensuring network reliability and uninterrupted service delivery has become a crucial challenge in network construction. In one type of network, a network device is deployed at the network egress. Services between the internal and external networks are processed and forwarded through this device. If this device fails, all services between the internal and external networks will be interrupted. Therefore, if only one device is used at this critical location in the network, no matter how reliable it is, there is always the risk of network disruption due to a single point of failure.

[0003] Therefore, two network devices are usually deployed at key locations on the network to improve network reliability. When the primary device fails, traffic is forwarded through the backup device, ensuring uninterrupted service between the internal and external networks. For traditional network devices (such as switches and routers), only Layer 2 network redundancy and routing table backup are required to ensure uninterrupted service transmission. However, for devices that require status detection and policy processing of messages (such as firewalls, intrusion prevention, web firewalls, and Internet behavior auditing), the legitimacy of the first packet of a flow will be checked and a session will be established to record the message status information (including the message's source IP, source port, destination IP, destination port, protocol, etc.). Subsequent packets of this flow will only be processed and forwarded on such devices if they match the session. If subsequent packets do not match the session, they will be discarded.

[0004] Therefore, when deploying such devices in dual-node deployment, consistency of service entry information and key configuration information between the two devices is essential to ensure uninterrupted service delivery. Hot standby can ensure consistency of service entry information and key configuration information between the two devices, but hot standby frequently executes memory allocation and deallocation processes, resulting in high performance overhead. Furthermore, all information must be copied, further increasing performance overhead. Summary of the Invention

It should also be understood that the term "and / or" as used herein refers to any or all possible combinations of one or more of the associated listed items.

[0024] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other.

Depending on the context, the word "if" used may be interpreted as "at the time of" or "when" or "in response to determining".

[0025] In one technical solution, a memory pool is allocated during initialization to construct hot standby messages. After a device processes a service message and establishes a session, it requests memory space, copies session information, service information, and message information into this memory pool, constructs the message protocol information, and then sends the hot standby message to other devices. After successful transmission, the memory is released for reuse the next time a session is established. This solution frequently executes memory allocation and deallocation processes, resulting in high performance overhead. Furthermore, all information needs to be copied, further increasing performance overhead.

[0026] In view of this, the present disclosure provides a hot backup processing method, device, electronic device, and machine-readable storage medium to improve the above-mentioned problem of high hot backup performance overhead.

[0027] Specifically, the technical solution is described below.

[0028] In one embodiment, the present disclosure provides a hot standby processing method, which is applied to a hot standby device, the method comprising: creating an associated session in a reserved space and generating associated service table item information based on a received message; obtaining a dedicated space address in the reserved space, and filling the dedicated space with hot standby message unique information associated with the session; generating a hot standby message based on the hot standby message public information, service table item information and hot standby message unique information, and forwarding the hot standby message so that the hot standby device on the opposite end completes hot standby according to the hot standby message; the hot standby message public information is fixed information generated based on the configured hot standby function.

[0029] Specifically, if Figure 1 , including the following steps:

[0030] Step S11: creating an associated session in the reserved space according to the received message and generating associated service entry information;

[0031] Step S12: obtaining a dedicated space address in the reserved space, and filling the dedicated space with unique information of the hot standby message associated with the session;

[0032] Step S13: generating a hot standby message according to the hot standby message common information, the service table information and the hot standby message unique information, and forwarding the hot standby message.

[0033] A dedicated reserved space is allocated in the memory for hot backup. At the same time, a dedicated space is allocated in the reserved space to fill in the unique information of the hot backup message. When the hot backup is completed, the reserved space in the memory is used to complete the hot backup process, thereby avoiding frequent execution of memory application and recovery processes. At the same time, associated fixed information is generated for the public information of the hot backup message, and the fixed information is no longer copied each time in the hot backup process. In summary, performance overhead is reduced.

[0034] In one embodiment, the hot standby message public information includes a source MAC address, a destination MAC address, a source IP address, and a destination IP address.

[0035] In one embodiment, obtaining a dedicated space address in the reserved space and filling the dedicated space with the hot standby message unique information associated with the session includes: reclaiming the dedicated space after forwarding the hot standby message.

[0036] In one embodiment, the present disclosure provides a hot standby processing method, which is applied to a hot standby device, the method comprising: receiving a hot standby message sent by a peer hot standby device, and completing hot standby according to the hot standby message; the hot standby message is generated by the peer hot standby device according to the hot standby message common information, service table information, and hot standby message unique information; the hot standby message common information is fixed information generated by the peer hot standby device according to the configured hot standby function; the service table information is generated by the peer hot standby device by creating an associated session in a reserved space based on the received message; and the hot standby message unique information is filled in a dedicated space of the reserved space of the peer hot standby device. This embodiment is the peer hot standby device in the aforementioned embodiment, i.e., the backup hot standby device.

[0037] When the memory pool is initialized, reserved space corresponding to the hot standby message is reserved. Space is reserved according to the hot standby service needs to ensure that no memory application is required.

[0038] When the user configures the hot standby function, hot standby message public information is generated. Due to dual-machine hot standby, the address information of the two hot standby devices will not change in the normal process. This data generally includes the second and third layer information of the message, such as the source MAC address, destination MAC address, source IP address, and destination IP address. More fixed information related to the hot standby business can also be added according to the actual business situation.

[0039] When receiving a message, the primary hot standby device distinguishes the message that needs to create a session according to the message type, allocates it to the memory of the hot standby reserved space, then creates the associated session, generates the associated business table entry information, and obtains the corresponding dedicated space control structure through the general space control structure of the message space in the memory, thereby obtaining the dedicated space reserved during initialization, and filling the dedicated space with the hot standby message-specific information.

[0040] The hot standby message is generated by gathering three pieces of data: common hot standby message information, service table information, and hot standby message-specific information. This information is then forwarded via the network interface card (NIC) to enable the hot standby device on the other end to complete the hot standby process. After the NIC completes the transmission, it reclaims the resources used in the aforementioned service and continues processing service messages, freeing up dedicated space for the next hot standby message generation and forwarding process.

[0042] In one embodiment, the hot standby message public information includes a source MAC address, a destination MAC address, a source IP address, and a destination IP address.

[0043] In one embodiment, obtaining a dedicated space address in the reserved space and filling the dedicated space with the hot standby message unique information associated with the session includes: reclaiming the dedicated space after forwarding the hot standby message.

[0044] In one embodiment, the present disclosure also provides a hot backup processing device, which is applied to a hot backup device, and the device includes: a receiving module, which is used to receive a hot backup message sent by the hot backup device at the opposite end, and complete hot backup according to the hot backup message; the hot backup message is generated by the hot backup device at the opposite end according to the hot backup message public information, service table information and hot backup message unique information; the hot backup message public information is fixed information generated by the hot backup device at the opposite end according to the configured hot backup function; the service table item information is generated by the hot backup device at the opposite end according to the received message, creating an associated session in the reserved space; the hot backup message unique information is filled in the dedicated space of the reserved space of the hot backup device at the opposite end.
