Description

Dual-computer hot standby 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 dual-computer hot standby processing method, apparatus, device, and machine-readable storage medium.
Background
RBM, Remote Backup Group, Remote Backup management; SCTP, Stream Control Transmission Protocol; FW, FireWall.
With the rapid development of cloud computing, enterprises can conveniently access a cloud computing network to acquire resources such as servers, storage, applications and the like, so that the investment cost for constructing IT infrastructure is reduced, and the informatization process is greatly accelerated. The virtual firewall is provided for solving the network resource access control in the virtual computing environment, and solves the network security problem in the virtual environment which cannot be dealt with by the traditional firewall to a certain extent. In the cloud computing network, a dual-computer hot standby state of a main standby backup mode is formed between two firewalls, so that the reliability is improved, and service interruption caused by the failure of one device is prevented.
How to ensure the reliability of the network, especially the uninterrupted transmission of the services in the virtualization environment, becomes a problem that must be solved in the network construction. The gateway device is generally deployed at the exit of the network, and the traffic between the internal and external networks is processed and forwarded through the device. 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. In a virtualized environment, the problem that two virtual firewalls span a three-layer network needs to be considered in the dual-machine deployment of the virtual firewalls, and the two virtual firewalls generally cannot be directly connected with the main device and the standby device through a physical interface. Secondly, when the dual-machine deployment is performed, the consistency of the service table item information and the key configuration information between the two devices needs to be ensured. The dual-computer hot standby function provides a special backup channel through the RBM, and is used for backing up state information and configuration information such as conversation and the like between two devices. The method is currently used for bearing information needing interaction between two devices, uses TCP as a transport layer protocol, uses the TCP connection as a control channel to carry out command interaction after the TCP connection is established, and uses a two-layer link as a data channel, and directly carries out transparent transmission on a data message without encapsulating an IP message header so as to solve the problem of hot standby of key information. However, in such TCP connections, a byte loss anywhere in a single byte stream will block the delivery of all data thereafter on the connection until the loss is repaired, relying on a single control channel to detect the availability of the RBM channel, and resulting in poor reliability.

It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information in the embodiments of the present disclosure, such information should not be limited by these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. Depending on the context, moreover, the word "if" as used may be interpreted as "at … …" or "when … …" or "in response to a determination".
In one scheme, the dual-computer hot standby function provides a special backup Channel through an RBM, a Control Channel (Control Channel) of the dual-computer hot standby function uses a TCP as a transport layer protocol, and after a TCP connection is established, a main device and a standby device interact with an RBM message through the RBM Channel; and the Data Channel (Data Channel) uses a two-layer transparent transmission mode, and the driving module directly transmits the Data message to the opposite end without packaging an IP head. In the cloud security field, the virtual FW dual-computer system is basically impossible to connect in a manner similar to physical connection, so that communication is inevitably required to be carried out through encapsulation of a bearing layer, the existing data channel message format has no IP message header, and the direct processing is driven between directly connected physical walls and can be normally used; however, in cloud security applications, a virtual firewall may need to span multiple virtual networks, and it is impossible to directly drive processing between layers, so that a manner of directly transmitting data through a data channel is very limited, and improvement is needed. The single control channel of the scheme has limitations, the control channel adopts a TCP protocol, the types of the messages which can be transmitted comprise an operation state message of a remote backup group, a consistency check message, a message of synchronous configuration information and the like, if the TCP protocol of the control channel is blocked or vibrates, the dual-computer hot standby system cannot work normally and is changed into two isolated systems, namely the two isolated systems are unstable and are easy to cause problems, and the data channel can only transmit hot standby or transparent two-layer messages and cannot participate in the forwarding of the control messages, so the single control channel has great limitations. In the aspects of reliability and fault detection of the scheme, a fault of a certain device in the dual-computer system is judged only by depending on the detection of a single control channel, false alarm is easily caused if port oscillation occurs, and secondly, the current dual-computer state, namely link fault or failure of opposite-end equipment and the like, cannot be accurately judged basically if the single control channel fails. This approach has design deficiencies.
In view of the above, the present disclosure provides a dual-computer hot standby processing method and apparatus, an electronic device, and a machine-readable storage medium, so as to solve the problem of poor reliability of the RBM backup channel.
Specifically, the technical scheme is as follows.
In one embodiment, the present disclosure provides a dual-computer hot-standby processing method, applied to an RBM device, the method including: initiating an SCTP connection request to an opposite-end RBM device, and establishing SCTP connection with the opposite-end RBM device responding to the SCTP connection request; checking the consistency of configuration information of a local RBM device and an opposite-end RBM device through an SCTP connection channel; and synchronizing the configuration information of the local RBM equipment and the opposite-end RBM equipment through the SCTP connection channel according to the check result.
Specifically, as shown in fig. 1, the method comprises the following steps:
step S11, initiating an SCTP connection request to an opposite-end RBM device, and establishing SCTP connection with the opposite-end RBM device responding to the SCTP connection request;
step S12, checking the consistency of the configuration information of the local RBM equipment and the opposite-end RBM equipment through the SCTP connection channel;
and step S13, synchronizing the configuration information of the local RBM equipment and the opposite-end RBM equipment through the SCTP connection channel according to the checking result.
And establishing an RBM backup channel between RBM equipment through SCTP, and synchronizing configuration information of the main RBM equipment and the standby RBM equipment by using the SCTP channel, so that the delivery of messages on other streams related to one stream cannot be blocked by the loss of a certain message on one stream.
In one embodiment, the initiating an SCTP connection request to an opposite-end RBM device and establishing an SCTP connection with the opposite-end RBM device responding to the SCTP connection request includes: and initiating an SCTP connection request to the RBM equipment at the opposite end, wherein the local RBM equipment at least uses two addresses, and establishes a path with at least two addresses of the RBM equipment at the opposite end responding to the SCTP connection request respectively to form coupling of at least four paths.
In one embodiment, one of the at least four coupled paths is used to synchronize configuration information with the opposite-end RBM device, and if the currently used path fails, the currently used path is preferentially switched to the path with the unchanged address of the local RBM device.
In one embodiment, if all of the at least four paths fail, the local RBM device is decoupled from the peer RBM device.
The embodiment provided by the present disclosure is described by taking an example in which the main RBM device is a local RBM device and the standby RBM device is an opposite-end RBM device. The main RBM equipment and the standby RBM equipment are connected through a plurality of physical links or a plurality of cross-three-layer network channels, and the SCTP runs on the plurality of links and is used for realizing the backup of key configuration information and service table items between the two equipment. Both endpoints of the SCTP protocol determine a association, and both SCTP endpoints of a SCTP association can be configured with multiple IP addresses, such that there are multiple paths between the two endpoints of a single association. Taking the case that the main RBM device uses two IP addresses a1 and a2 and the standby RBM device uses two IP addresses B1 and B2 as an example, the IP addresses configured for SCTP connection on the main RBM device and the standby RBM device are both accessed to the same VLAN, so that four link paths can be established, and thus a coupling includes four paths (Path0, Path1, Path2, and Path3), where one Path can be configured as a preferred Path, such as preferred Path 0. The SCTP packet sent by the master RBM device transport address AQ is sent to the standby RBM device B1 through the preferred Path 0. When the preferred Path fails, the SCTP may automatically switch to another standby Path, and preferentially switch to a Path with a constant transport address on the primary RBM device, for example, switch to a Path1 between a1 and B2, and switch the transport address of the local endpoint again.
The SCTP is used to complete the state consistency detection and the backup of key information between the main equipment and the standby equipment, the RBM module is responsible for collecting the running state and the table items of the characteristics of each module of the safety equipment,
and establishing the SCTP coupling, wherein when an RBM coupling channel is established, the equipment compares the configured maximum value IP _ Max1 of all IP address groups of the local terminal with the maximum value IP _ Max2 of the IP address group of the opposite terminal, the equipment with a larger IP _ Max address is used as a Server, and the equipment with a smaller IP _ Max address is used as a Client. The Client initiates an SCTP connection request to the Server to establish a plurality of SCTP channel paths of the linkage RBM module.
When the dual-computer configuration automatic backup function is started, the RBM module can carry out dual-computer state consistency detection through the SCTP coupling channel. The RBM detects whether the configuration information of the two devices is consistent through the SCTP coupling channel interaction consistency check message, and is used for preventing the situation that the service is not communicated after the main/standby switching due to the inconsistency of the configuration information of the two devices. When the configuration information is inconsistent, the device sends log information to prompt an administrator to perform manual synchronization of the configuration information. The master device and the slave device send consistency check request messages to the slave device and collect the abstract of the self-related module configuration information. After receiving the consistency check request, the standby equipment collects the abstract of the configuration information of the relevant module of the standby equipment, and then encapsulates the abstract into a consistency check message and returns the consistency check message to the main equipment. And after receiving the consistency check message returned by the standby equipment, the main equipment compares the abstract of the configuration information of the main equipment with the abstract of the configuration information of the standby equipment, and if the comparison result is inconsistent, the main equipment outputs the log information.
When the dual-computer configuration automatic backup function is started, the RBM module can perform real-time backup and batch backup through the SCTP coupling channel. The real-time backup, that is, the configuration information newly added, deleted or modified on the main device is backed up to the standby device in real time, so as to ensure the consistency of the changed configuration information on the main device and the standby device. The batch backup is that all the key configuration information on the main device is backed up to the standby device, and the configuration inconsistent with that on the main device is deleted on the standby device, so that the key configuration information is ensured to be completely consistent on the main device and the standby device. After the automatic backup function of the configuration information is started, the main device immediately carries out one-time batch backup on the existing key configuration information, and then newly added, deleted or modified configuration information is backed up in real time. After the automatic backup function of the configuration information is started, the equipment is triggered to perform batch backup when the SCTP coupling is successfully established for the first time, the equipment is restarted or the process is restarted.
Based on the SCTP coupling path, the service table entry information generated on the main equipment can be backed up to the standby equipment in real time, and the problem of service interruption caused by the missing of the service table entry on the standby equipment when the main equipment and the standby equipment are switched is avoided. For each dynamically generated connection, a session entry corresponds to the device that needs to perform state detection on the packet. The main device creates a plurality of session table items in the process of processing the service; and the standby equipment does not pass through the message, so that a session table entry is not created. The real-time backup function of the service table entry is realized through the SCTP coupling path, the main device can backup the session table entry to the standby device in real time, and after the main device and the standby device are switched, the subsequent service message which is connected can keep the service uninterrupted by matching the session table entry backed up. The safety business table item for basically supporting hot standby comprises the following steps: session table entries, session association table entries, NAT port block table entries and service table entries generated by each security service module itself.
The multiple link channels monitor the connectivity of the links based on the keep-alive mechanism of the SCTP protocol itself. When the keep-alive mechanism of the SCTP detects that the link is disconnected, the RBM connection channel is disconnected; if one SCTP channel has keep-alive channel, then RBM channel works normally and sends the log of link failure of other channels. If all SCTP protocol paths fail, the coupling between the two ends can fail and be disconnected. Therefore, the link detection mechanism based on the SCTP multi-protocol coupling path has higher reliability and higher accuracy than the existing single-channel detection scheme.
In an embodiment, the present disclosure also provides a dual-machine hot-standby processing apparatus, as shown in fig. 2, applied to an RBM device, the apparatus including: the connection module 21 is configured to initiate an SCTP connection request to an opposite-end RBM device, and establish an SCTP connection with the opposite-end RBM device that responds to the SCTP connection request; the checking module 22 is configured to check consistency of configuration information of the local RBM device and the peer RBM device through the SCTP connection channel; and the synchronizing module 23 is configured to synchronize configuration information of the local RBM device and the peer RBM device through the SCTP connection channel according to the check result.
In one embodiment, the initiating an SCTP connection request to an opposite-end RBM device and establishing an SCTP connection with the opposite-end RBM device responding to the SCTP connection request includes: and initiating an SCTP connection request to the opposite-end RBM equipment, wherein the local RBM equipment establishes a path with at least two addresses of the opposite-end RBM equipment responding to the SCTP connection request respectively by using the at least two addresses, and forms coupling of at least four paths.
In one embodiment, one of the at least four coupled paths is used to synchronize configuration information with the opposite-end RBM device, and if the currently used path fails, the currently used path is preferentially switched to the path with the unchanged address of the local RBM device.
In one embodiment, if all of the at least four paths fail, the local RBM device is decoupled from the peer RBM device.
