Description

Hot backup processing method, device, equipment and machine readable storage medium
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a hot backup processing method, apparatus, device, and machine-readable storage medium.
Background
With the rapid development of the digital transformation of the internet and various industries, more and more services are carried by the network, and the importance of the services is increased. How to ensure the reliability of the network and the uninterrupted transmission of the services becomes a problem which needs to be solved in the network construction. In a networking, a certain network device is deployed at an exit of a network, and services between an internal network and an external network are processed and forwarded through the network device, and if the network device fails, all the services between the internal network and the external network are interrupted, so that in the case that only one device is used at the key position of the network, no matter how high the reliability is, the risk of network interruption caused by single-point failure of the device exists.
Therefore, two network devices are usually deployed at key positions of the network to improve the reliability of the network. When the main equipment fails, the flow can be forwarded through the standby equipment, and the uninterrupted operation of the service between the internal network and the external network is ensured. For traditional network devices (such as switches and routers), uninterrupted transmission of services can be ensured only by making redundancy of a two-layer network and backup of routing table entries. However, for devices that need to perform state detection and policy processing on a packet (such as a firewall, intrusion prevention, a web firewall, and internet behavior audit), it performs validity detection on the first packet of a flow, and establishes a session to record state information of the packet (including a source IP, a source port, a destination IP, a destination port, and a protocol of the packet). And the subsequent message of the flow can be processed on the equipment and message forwarding is completed only if the session is matched, and the subsequent message can be discarded if the session cannot be matched.
Therefore, when such a device performs dual-machine deployment, it is also necessary to ensure the consistency of the service table entry information and the key configuration information between two devices, and thus, it is only possible to ensure uninterrupted transmission of services. The hot backup function can realize the consistency between the service table item information and the key configuration information of the two devices, but the hot backup frequently executes the memory application and recovery process, the performance cost is high, and all the information needs to be copied, thereby further increasing the performance cost.
