Description
Technical Field
The application relates to the technical field of network communication, in particular to a method and a device for synchronizing main and standby main control configurations based on frame type equipment.
Background
An operating system Level Virtual environment (OVC) is a virtualization technology for virtualizing a physical device into a plurality of logical devices. After OVC virtualization, a plurality of logical devices on the same physical device have independent hardware, software, forwarding table entries, management planes and logs, and the operation of the logical devices is not affected. The OVC technology realizes the virtualization of resources and management, after the resources of the physical equipment are pooled, the rapid deployment and adjustment of services are not limited by the physical equipment, the advantages of saving construction and operation and maintenance cost, flexible deployment according to needs, complete fault isolation and the like are realized, and the problems of multi-service safety isolation and resource allocation according to needs are effectively solved. And a basic condition is created for the network security to change the omni-directional dynamic and elastic cloud service mode. The OVC technology enables the system to perform independent process management, memory management and disk management aiming at each virtual device, and resource consumption and performance loss caused by switching and scheduling among the virtual devices are avoided. And the kernel of the operating system finishes the scheduling among the OVCs and distributes hardware resources for each OVC according to a preset resource template.
The frame type equipment is composed of a frame and a board card inserted on the frame, the double-master control equipment refers to equipment which supports two master control boards to be in place at the same time, only one of the two master control boards can be used as a master control and is responsible for communicating with all interface boards (including issuing various table entries, receiving and sending messages and responding various events) and controlling the operation of the whole equipment, the other master control board is a standby master control, the standby master control can not communicate with the interface boards and interfere the operation of the whole equipment, and is only responsible for receiving backup data backed up from the master control. Once the main master fails, the standby master is switched to a new main master to start to control the operation of the entire device, and in order that the new main master can seamlessly take over all the work of the original main master, the standby master must have the same data (including single board information, interface information, various configuration information, various table entries, and storage location information of the table entries in the interface board chip) as the main master.
Usually, a default OVC is provided on the frame device, and it is assumed that OVC0 is provided, all physical ports on the frame device and physical ports of an internal channel between the main master control and the standby master control all belong to OVC0, the main master control and the standby master control have respective Web processes, which are a main master control Web (Web) process and a standby master control Web process of OVC0, respectively, and a communication connection is established between the main master control Web process and the standby master control Web process of OVC0 through the internal channel between the main master control and the standby master control, so as to synchronize received configuration information issued by a user through the Web pages to the standby master control Web process, thereby ensuring that the configuration information of the two master controls can be synchronized in real time. After an OVC is newly created, a new main control Web process and a new standby control Web process are created in the OVC to manage configuration information of the corresponding OVC, and meanwhile, part of physical ports can be divided into the OVC, only one object channel port of an internal channel between the main control and the standby control belongs to one OVC, and usually, the physical port corresponding to the internal channel belongs to the OVC 0. Therefore, there is no internal channel between the main master control Web process and the standby master control Web process of the newly-built OVC, and communication connection cannot be established, that is, the configuration information received by the main master control Web process of the newly-built OVC cannot be synchronized into the standby master control Web process, which may cause inconsistency of the configuration information between the main master control and the standby master control, affect normal service processing of the frame device, and further affect network security.

In order to solve the above problem, an embodiment of the present invention provides a method for synchronizing configuration of a main master control and a standby master control based on a frame device, so as to ensure that configuration information between the main master control and the standby master control is consistent, and the frame device can normally perform service processing, thereby ensuring network security. Please refer to fig. 1, fig. 1 is a flowchart of a method for synchronizing configuration of a main and standby main controls based on a frame device shown in this application, a main control and a standby main control of the frame device are connected by an internal channel, the main control and the standby main control are provided with at least two OVCs, an internal channel is used between a main control internal interface of a first OVC and a standby main control internal interface of the first OVC in the at least two OVCs, the method is applied to a main Web process of other OVCs except the first OVC in the at least two OVCs, an Internet Protocol (Internet Protocol, IP) address of a main control virtual interface of the other OVCs except the first OVC in the at least two OVCs is the same as an IP address of the main control internal interface of the first OVC, an IP address of a standby main control virtual interface of the other OVCs except the first OVC in the at least two OVCs is the same as an address of the standby main control internal interface of the first OVC, and an identifier of a virtual standby main control virtual master control interface of the other OVCs except the first OVC in the at least two OVCs are the same as an IP address of the standby virtual master control internal interface of the standby virtual control internal interface of the first OVC, and an identifier of the virtual master control virtual interface of the virtual control except the virtual control of the virtual control other OVC in the virtual control except the first OVC in the at least two OVC are the virtual control The virtual interfaces of the virtual interfaces have the same identifier, which may be but not limited to the identifier of the corresponding OVC, and the method includes:
s11: and the main control Web process of the current OVC acquires the configuration information to be synchronized.

The specific process of the step is as follows: encapsulating the configuration information to be synchronized in a synchronization request message; setting a source IP address of the synchronization request message as an IP address of a main control virtual interface of the current OVC, and setting a target IP address of the synchronization request message as an IP address of a standby main control virtual interface of the current OVC; and writing the virtual interface identifier of the main control virtual interface of the current OVC in the synchronous request message.

In an alternative embodiment, the method further comprises:
receiving a synchronization response message through a communication connection;
the communication connection is disconnected.
After the synchronization response message is the to-be-synchronized configuration information in the synchronization request message acquired by the standby master control Web process of the current OVC, the synchronization response message may be generated and forwarded to the master controller according to the IP address of the master control virtual interface of the current OVC, the IP address of the standby master control virtual interface of the current OVC, and the virtual interface identifier of the master control virtual interface of the current OVC, and the standby master controller forwards the generated synchronization response message to the virtual interface corresponding to the virtual interface identifier carried in the synchronization request message.
After receiving the synchronization response message, the primary master control Web process of the current OVC indicates that the standby master control Web process of the current OVC has acquired the information to be configured synchronously.
Please refer to fig. 2, fig. 2 is another method for synchronizing configuration of a master/standby main control based on a frame device shown in this application, where the master main control and the standby main control of the frame device are connected by an internal channel, the master main control and the standby main control are provided with at least two OVCs, and an internal channel is used between a master main control internal interface of a first OVC and a standby main control internal interface of the first OVC in the at least two OVCs, and the method is applied to a standby main control Web process of other OVCs except the first OVC in the at least two OVCs, where internet protocol IP addresses of master main virtual interfaces of the other OVCs except the first OVC in the at least two OVCs are the same as an IP address of a master main internal interface of the first OVC, IP addresses of standby main virtual interfaces of the other OVCs except the first OVC in the at least two OVCs are the same as an IP address of a standby main virtual interface of the first OVC, and a virtual interface identifier of a standby virtual interface of the other OVCs except the first OVC in the at least two OVCs are the same as a virtual interface identifier of a virtual interface of the standby main control Also, the above method comprises:
s21: and the standby main control Web process of the current OVC establishes communication connection between the main control virtual interface of the current OVC and the standby main control virtual interface of the current OVC.
S22: a synchronization request message is received over a communication connection.
The synchronous request message is generated and forwarded to the standby main control by the main control Web process of the current OVC according to the configuration information to be synchronized, the IP address of the main control virtual interface of the current OVC, the IP address of the standby main control virtual interface of the current OVC and the virtual interface identifier of the main control virtual interface of the current OVC, and the standby main control forwards the generated synchronous request message to the virtual interface corresponding to the virtual interface identifier carried by the synchronous request message.
S23: and acquiring the configuration information to be synchronized in the synchronization request message.
According to the technical scheme provided by the application, a main master control Web process of the current OVC can establish communication connection between a main master control virtual interface of the current OVC and a standby master control virtual interface of the current OVC, a synchronization request message generated based on to-be-synchronized configuration information and a virtual interface identifier of the main master control virtual interface of the current OVC is sent to a standby master control through the communication connection, the standby master control forwards the synchronization request message to a virtual interface corresponding to the virtual interface identifier carried by the synchronization request message, and the virtual interface identifiers of the main master control virtual interfaces of other OVCs except for the first OVC in at least two OVCs are the same as the virtual interface identifier of the standby master control virtual interface, so that the standby master control can forward the synchronization request message to the standby master control virtual interface of the current OVC, thereby ensuring that the standby master control of the current OVC obtains the to-be-synchronized configuration information and ensuring that the main master control Web process can establish communication connection between the main master control virtual interface of the current OVC and the standby master control virtual interface of the current OVC, Configuration information between the standby main controls is consistent, and then the frame type equipment can normally process services, so that network safety is ensured.

sending a synchronous response message to the main master control through communication connection so that the main master control forwards the synchronous response message to a virtual interface corresponding to a virtual interface identifier carried by the synchronous response message;
the communication connection is disconnected.
After the standby master control Web process of the current OVC acquires the information to be synchronized, in order to save network resources, a synchronization response message may be sent to the main master control Web process of the current OVC, and then the communication connection established before is disconnected.
The generating of the synchronous response message according to the IP address of the main master control virtual interface of the current OVC, the IP address of the standby master control virtual interface of the current OVC, and the virtual interface identifier of the standby master control virtual interface of the current OVC specifically includes:

and writing the virtual interface identifier of the standby main control virtual interface of the current OVC in the synchronous response message.
The virtual interface identifier may be written in a setting field of the synchronization request response packet, and the setting field and the virtual interface identifier may be set according to actual needs.
Referring to fig. 3, fig. 3 is a diagram illustrating another method for synchronizing main and standby main control configurations based on a frame device according to the present application, where when the frame device does not turn on an OVC function, there is only one default OVC on the frame device, which may be defined as OVC 0. The primary master control only has one primary master control Web process, the standby master control also only has one standby master control Web process, both belong to OVC0 and are respectively represented by OVC0_ WEB _ M, OVC0_ WEB _ B, and subscript M, B respectively represents the primary master control and the standby master control. The configuration information on the main master control Web process can be sent to the standby master control Web process through an internal channel between the main master control and the standby master control, and the effect of configuration synchronization can be achieved. The physical interface ieth0_2 of the internal channel belongs to the OVC0, the address of ieth0_2 on the main master is 127.2.0.2, and the address of ieth0_2 on the standby master is 127.2.0.3. The main control Web process and the standby control Web process of the OVC0 have direct routing and can be intercommunicated.
After the frame device starts the OVC function, n OVCs, such as OVC1, OVC2, … …, OVCn, etc., may be created. In this embodiment, OVC1 is taken as an example to illustrate a complete technical solution of the present application. When the frame device needs to create the OVC1, the operation of creating the OVC1 is performed by accessing the Web process of the primary master control of the OVC0 and issuing the configuration information, so the configuration information is synchronized to the secondary master control, and the OVC1 is created on the secondary master control synchronously. The OVC1 of the master and the standby master may have partial resources on the frame device, such as physical ports, Central Processing Unit (CPU) resources, and the like. Meanwhile, the main master and the standby master can automatically create a Web process under the OVC1, which is respectively represented as OVC1_ WEB _ M, OVC1_ WEB _ B. Users can respectively access OVC1_ WEB _ M of OVC1 to carry out configuration, OVC1_ WEB _ B is in a silent state and is only used for processing configuration information synchronously coming from OVC1_ WEB _ M, and the state is switched after main/standby switching, so that the effect is the same.
At this time, the primary master has OVC0_ WEB _ M, OVC1_ WEB _ M, and the backup master has OVC0_ WEB _ B, OVC1_ WEB _ B. Among them, there is physical interface ieth0_2 of the internal channel between OVC0_ WEB _ M and OVC0_ WEB _ B, and physical interface ieth0_2 of the internal channel can only belong to OVC0, and IP addresses of physical interface ieth0_2 of the internal channel can be intercommunicated between OVC0_ WEB _ M and OVC0_ WEB _ B. However, there is no actual physical interface between OVC1_ WEB _ M and OVC1_ WEB _ B for intercommunication, and if an internal physical interface is used exclusively for configuration information synchronization between the same OVCs on each main control and each standby control, waste of physical ports is caused, and since the number of physical ports that can be connected by an exchange chip on the frame device is limited, network connection cannot be directly established between OVCs 1 on the main control and the standby control.
In order to solve the above problem, when creating the OVC1, a virtual interface ieth0_2.1 is created for the primary master control Web process and the secondary master control Web process of the OVC1, respectively, and an IP address of a primary master control virtual interface ieth0_2.1 configured with the OVC1 is the same as an IP address of ieth0_2 on the primary master control, and is 127.2.0.2, and an IP address of a secondary master control virtual interface ieth0_2.1 configured with the OVC1 is the same as an IP address of ieth0_2 on the secondary master control, and is 127.2.0.3. Because the route between each OVC is isolated, the situation of IP conflict can not occur, and the configuration of the same IP address has the advantage that the connection flow in the configuration synchronization process is not required to be modified. Or using the address of 127.2.0.2 of the master to connect with the address of 127.2.0.3 of the backup master.
When configuration synchronization is carried out, the OVC1_ WEB _ M and the OVC1_ WEB _ B can establish communication connection through a virtual interface ieth0_2.1, and the OVC1_ WEB _ M generates a synchronization request message carrying ieth0_ 2.1; the synchronous request message is sent to a physical interface ieth0_2 of a standby master control through a physical interface ieth0_2 of the main master control by an OVC1_ WEB _ M, after the physical interface ieth0_2 of the standby master control receives the synchronous request message, the synchronous request message is sent to a virtual interface ieth0_2.1, ieth0_2.1 belongs to the OVC1, the OVC1_ WEB _ B can receive the synchronous request message to acquire the configuration information to be synchronized, and configuration synchronization is achieved through the process.
