In the presence of a master-slave, a daemon thread such as a keepalive thread and a conntrack thread needs to be created between each pair of master-slave virtual routers to ensure that data on each pair of master-slave virtual routers can keep synchronous.
However, this is problematic in that if the number of the master-standby virtual routers is large, many daemon threads need to be created and maintained, which inevitably consumes a large amount of computing and storage resources of the system.

Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1, according to the usage requirement of the user, a plurality of primary virtual routers are deployed on the cloud platform, and a standby virtual router corresponding to each primary virtual router is also deployed for each primary virtual router. In each pair of the master-slave virtual routers, the master virtual router represents a virtual router in a working state on the cloud platform, and the slave virtual router represents a virtual router in a non-working state on the cloud platform.
In this embodiment, each pair of master-slave virtual routers needs to implement not only data synchronization but also master-slave relationship synchronization. That is, when the operating state of each pair of the master-slave virtual routers changes, for example, one virtual router of two virtual routers corresponding to a certain pair of the master-slave virtual routers changes from the operating state to the non-operating state, and the other virtual router changes from the non-operating state to the operating state, the master-slave relationship of the pair of the master-slave virtual routers also needs to be correspondingly adjusted, the original master virtual router is adjusted to be the slave virtual router, and the original slave virtual router is adjusted to be the master virtual router.
Referring to fig. 1 and fig. 2 and fig. 3, an embodiment of the present application provides a state synchronization method for a virtual router, where the state synchronization method for the virtual router may be executed by two state synchronization software deployed on an electronic device, such as a terminal or a server, to implement data synchronization of each pair of master-slave virtual routers and implement master-slave relationship adjustment of each pair of master-slave virtual routers.
Specifically, the step of executing the state synchronization method of the virtual router may include:
step S100: the first state synchronization software acquires the current equipment state information of each main virtual router in a plurality of main virtual routers on the cloud platform.
Step S200: the first state synchronization software sends the device state information to the second state synchronization software.
Step S300: and the second state synchronization software correspondingly updates the equipment state information of the standby virtual router corresponding to each main virtual router according to the current equipment state information of the main virtual router.
It can be understood that, when the state synchronization method of the virtual router is executed, the state synchronization software is not limited to the two described in this embodiment, and may also be multiple state synchronization software, each master virtual router or standby virtual router is managed by corresponding one state synchronization software, and the number of the state synchronization software management is smaller than the number of all the master virtual routers on the cloud platform.
For example, there are three state synchronization software, and the first state synchronization software may send the current device state information of the master virtual router managed by the first state synchronization software to the remaining second and third state synchronization software; or, the first state synchronization software may also send the device state information to the second state synchronization software, and the second state synchronization software forwards the device state information to the third state synchronization software. In this way, both the second and third state synchronization software can obtain the device state information. If the standby virtual router corresponding to the primary virtual router managed by the first state synchronization software is managed by the third state synchronization software, the third state synchronization software updates the device state information of the corresponding standby virtual router based on the received device state information.
Of course, in order to facilitate understanding of the present solution, the present embodiment takes two state synchronization software as an example to illustrate the technical solution of the present application. And since the logic of each state synchronization software executing the state synchronization method of the virtual router is substantially the same, for the convenience of understanding, the present application is mainly described from the perspective of the first state synchronization software.
In this embodiment, a management table entry of a virtual router is preset in the first state synchronization software, and the management table entry records whether each virtual router managed by the first state synchronization software is currently a primary virtual router or a standby virtual router.
For example, the record of the management entry may be as shown in table 1 below:
| serial number | Virtual router numbering | Master-slave mark |
| 0 | XXX-FFF-1 | 1 |
| 1 | XXX-FFF-2 | 1 |
| 2 | XXX-FFF-3 | 1 |
| 3 | XXX-FFF-4 | 0 |
| 4 | XXX-FFF-5 | 0 |
TABLE 1
The state identifier is 1, which indicates that the virtual router is currently the main virtual router, and the state identifier is 0, which indicates that the virtual router is currently the standby virtual router. Obviously, of the 5 virtual routers managed by the first state synchronization software, the three virtual routers XXX-FFF-1, XXX-FFF-2 and XXX-FFF-3 are currently main virtual routers, and the two virtual routers XXX-FFF-4 and XXX-FFF-5 are currently standby virtual routers.
In this embodiment, the first state synchronization software may periodically acquire the device state information of each of the plurality of primary virtual routers managed by the first state synchronization software, so as to perform data synchronization. Then, when the current time reaches a set time point of the current cycle (the set time point is a time point at which the device state information acquisition needs to be performed, which may be a start time or an end time of each cycle), the electronic device may traverse the management table entry to determine a plurality of primary virtual routers that are currently primary (obtaining a virtual router number of each primary virtual router from the management table entry is to determine each primary virtual router).
Step S100: the first state synchronization software acquires the current equipment state information of each main virtual router in a plurality of main virtual routers on the cloud platform.
In this embodiment, the first state synchronization software pre-establishes a mapping relationship between a virtual router number and an address of each master virtual router managed by the first state synchronization software. After the virtual router number of each main virtual router is obtained, based on the mapping relation, the first state synchronization software can determine the address of each main virtual router, and then access is initiated to each main virtual router based on the address so as to obtain the current equipment state information of each main virtual router.
For example, since the logic for acquiring the device state information of each master virtual router managed by the first state synchronization software is substantially the same, for understanding, the present embodiment will be described by taking the example that the first state synchronization software acquires the device state information of a certain master virtual router.
In particular, based on the address of the primary virtual router, the first state synchronization software can generate and send an access request to the primary virtual router.
If the main virtual router is currently and actually in a working state, the main virtual router can return an access response to the first state synchronization software based on the access request. If the master virtual router is currently in an inoperative state, such as shutdown or failure, the master virtual router cannot return an access response to the first state synchronization software based on the access request.
Therefore, after sending the access request, the first state synchronization software may obtain the current operating state information of the primary virtual router by determining whether an access response returned by the primary virtual router is received.
Specifically, if the first state synchronization software receives an access response returned by the master virtual router, the first state synchronization software generates working state information for indicating that the master virtual router is currently in a working state; and if the first state synchronization software does not receive the access response returned by the main virtual router after time out, the first state synchronization software generates working state information for indicating that the main virtual router is in a non-working state currently.
Further, if the master virtual router is currently in an operating state, the first state synchronization software may generate a communication information obtaining request, where the communication information obtaining request is used to obtain communication information generated by communication between the master virtual router and other devices. By sending the communication information acquisition request to the master virtual router, the first state synchronization software can correspondingly receive the communication information returned by the master virtual router based on the communication information acquisition request, wherein the communication information records the time and the data of the master virtual router interacted with the device. In other words, when the master virtual router is currently in the working state, the acquiring, by the first state synchronization software, the current device state information of the master virtual router includes: the current operating state information and communication information of the primary virtual router.
If the main virtual router is currently in a non-working state, the first state synchronization software cannot acquire the communication information of the main virtual router even if the first state synchronization software continues to access the main virtual router. Therefore, after determining that the primary virtual router is currently in the non-operating state, the first state synchronization software does not need to acquire the information of the primary virtual router. In other words, when the master virtual router is currently in a non-working state, the first state synchronization software acquires that the current device state information of the master virtual router includes the current working state information of the master virtual router.
After the first state synchronization software obtains the current working state information of each master virtual router managed by the first state synchronization software, the first state synchronization software may execute step S200.
Step S200: the first state synchronization software sends the device state information to the second state synchronization software.
In order to facilitate data synchronization, after the current working state information of each master virtual router managed by the first state synchronization software is acquired, the first state synchronization software may send the current working state information of each master virtual router to the second state synchronization software for a first time.
In addition, since the current working state information can reflect whether the master virtual router is currently in a working state, in the process of generating the current working state information of each master virtual router managed by the first state synchronization software, the first state synchronization software can also determine which master virtual routers which are originally in the working state are currently in a non-working state.
If the primary virtual router originally in the working state is currently and actually in the non-working state, it is indicated that the primary virtual router is actually the standby virtual router. Therefore, the first state synchronization software needs to correspondingly adjust the primary/secondary relationship of the primary virtual router, that is, the primary/secondary identifier of the primary virtual router currently in the non-working state is adjusted from 1 to 0 in the management table entry, so as to adjust the primary virtual router to be the secondary virtual router.
For example, in table 1, two virtual routers XXX-FFF-1 and XXX-FFF-2 are currently in an inactive state, the first state synchronization software adjusts the active/standby identifiers of the two virtual routers from 1 to 0, so that the two virtual routers XXX-FFF-1 and XXX-FFF-2 are changed from the active virtual router to the standby virtual router. Table 2 obtained is as follows:
| serial number | Virtual router numbering | Master-slave mark |
| 0 | XXX-FFF-1 | 0 |
| 1 | XXX-FFF-2 | 0 |
| 2 | XXX-FFF-3 | 1 |
| 3 | XXX-FFF-4 | 0 |
| 4 | XXX-FFF-5 | 0 |
TABLE 2
Step S300: and the second state synchronization software correspondingly updates the equipment state information of the standby virtual router corresponding to each main virtual router according to the current equipment state information of the main virtual router.
In this embodiment, the second state synchronization software is pre-established with a corresponding relationship between each pair of the master-slave virtual routers. After the second state synchronization software receives the current device state information of each main virtual router, the second state synchronization software may search for a corresponding relationship according to the virtual router number of the main virtual router in the current device state information of each main virtual router, and determine a standby virtual router corresponding to each main virtual router.
In this embodiment, since the update logics of the device state information of each standby virtual router managed by the second state synchronization software are substantially the same, for convenience of understanding, the embodiment will be described by taking the example that the second state synchronization software updates the device state information of a certain standby virtual router.
Specifically, if the current device state information of the master virtual router corresponding to the standby virtual router includes: the current working state information and the communication information of the main virtual router indicate that the main virtual router is actually in a working state at present, and in this case, the second state synchronization software does not need to control the standby virtual router to start and continues to keep the standby virtual router in a non-working state of shutdown or standby. And the second state synchronization software can also update the communication information of the standby virtual router stored in the second state synchronization software by using the communication information of the main virtual router so as to realize data synchronization.
If the current device state information of the main virtual router corresponding to the standby virtual router only comprises: the current working state information of the main virtual router indicates that the main virtual router is actually in a non-working state currently. In one aspect, the second state synchronization software may control the standby virtual router to start up to ensure that service is not interrupted for a long time. On the other hand, the second state synchronization software updates the device state information of the standby virtual router, that is, the main-standby relationship of the standby virtual router is correspondingly adjusted. For example, the second state synchronization software may adjust the active/standby identifier of the standby virtual router from 0 to 1 in a management table entry preset by the second state synchronization software, so as to adjust the standby virtual router to the primary virtual router managed by the second state synchronization software.
In this embodiment, because there are other master virtual routers managed by the second state synchronization software besides the plurality of master virtual routers managed by the first state synchronization software on the cloud platform, and other standby virtual routers corresponding to the other master virtual routers on the cloud platform are also managed by the first state synchronization software, the first state synchronization software may also send current device state information of the other master virtual routers based on the second state synchronization software, and update the device state information of the other standby virtual routers.
Specifically, the first state synchronization software is pre-established with a corresponding relationship between each pair of the master-slave virtual routers. After the first state synchronization software receives the current device state information of the other main virtual router sent by the second state synchronization software, the first state synchronization software may search for the corresponding relationship according to the virtual router numbers of the other main virtual router in the current device state information of the other main virtual router, thereby determining the other standby virtual router corresponding to the other main virtual router.
Further, if the current device state information of the other virtual routers includes: the current working state information and the communication information of the other main virtual routers indicate that the other main virtual routers are actually in a working state at present, and in this case, the first state synchronization software does not need to control the other standby virtual routers to be started, and continues to keep the other standby virtual routers in a shutdown or standby non-working state. And the first state synchronization software can also update the communication information of the other standby virtual router stored on the first state synchronization software by using the communication information of the other main virtual router so as to realize the synchronization of data.
If the current device state information of the other main virtual router only includes: the current working state information of the other main virtual router indicates that the main virtual router is actually in a non-working state currently. In this case, on the one hand, the first state synchronization software may also control the other standby virtual routers to start up, so as to ensure that the service is not interrupted for a long time. On the other hand, the first state synchronization software updates the device state information of the other standby virtual router, that is, correspondingly adjusts the main-standby relationship of the other standby virtual router. For example, the first state synchronization software may also adjust the active/standby identifier of the other standby virtual router from 0 to 1 in a management table entry preset by the first state synchronization software, so as to adjust the other standby virtual router to another primary virtual router managed by the first state synchronization software.
