Referring to fig. 1, in order to implement a schematic diagram of two switch devices in a mutual standby scheme, the schematic diagram includes two switch devices (SW1 and SW2), each switch device includes two main control boards (SW1 includes main control board 11 and main control board 12, and SW2 includes main control board 21 and main control board 22).
In addition, as shown in fig. 1, an SDN controller is installed in each switching device (an SDN controller 1 is installed in SW1, and an SDN controller 2 is installed in SW2), and the SDN controller is installed in an operating system (e.g., an X86 system, not shown in fig. 1) pre-integrated in the switching device. Of course, the present invention does not limit the control software installed in the operating system, for example, the control software may also be network management software, which is only described by taking an SDN controller as an example. These control software are used to implement specific control functions, and can be regarded as virtual network devices (hereinafter referred to as network devices).
The switching device may select a main switching device and a standby switching device through main/standby elections, for example, election SW1 is the main switching device, and SW2 is the standby switching device; similarly, active/standby elections also need to be performed between network devices (SDN controller 1 and SDN controller 2) running on different switching devices, for example, the SDN controller 2 is elected to be a master controller, and the SDN controller 1 is elected to be a slave controller.
It should be noted that, in consideration of fully utilizing device resources, the SDN controller is installed on the switching device, but the SDN controller and the switching device are functionally independent, and therefore, the primary and secondary elections of the switching device and the primary and secondary elections of the network device (SDN controller) are generally independent from each other, which may cause inconsistency between the primary and secondary elected switching devices and the primary and secondary network devices, and as a result of the foregoing elections, the controller (SDN controller 2) is running on the primary switching device (SW1), which brings inconvenience to network management of an enterprise.
In order to solve the above problems, the present invention provides a method for synchronizing a master device and a slave device, where a correspondence relationship between an MAC address of a master control board in a switching device and a device identifier of a network device running on the switching device is preset, and when a network device receives an MAC address of a target master control board notified by a master control board (denoted as a target master control board) located on the master switching device, a device identifier (denoted as a target device identifier) of the network device corresponding to the MAC address of the target master control board may be determined based on the correspondence relationship, and the network device represented by the target device identifier is the network device running on the master switching device.
In order to make the objects, technical solutions and advantages of the present invention clearer, the following detailed description of the present invention is provided with reference to the accompanying drawings and specific embodiments:
referring to fig. 2, a flowchart of a primary/standby synchronization method according to the present invention is shown, where the flow is applied to a network device running on a switching device, for example, an SDN controller running on the switching device.
As shown in fig. 2, the process may include the following steps:
step 201, obtaining the MAC address of the target main control board notified by the target main control board.
The target master control board is the master control board on the selected master switch device, so called the target master control board, and is named for convenience of description only and is not limiting. The main-standby election of the switching device can be realized by adopting the existing election mode, and the details are not repeated here.
In the present invention, as an embodiment, after performing the primary and standby elections of the switch device each time, the target main control board on the elected primary switch device notifies all network devices in the network of the MAC address of the target main control board.
In the present invention, as another embodiment, the MAC address of the target master board may be periodically notified to all network devices in the network by the target master board on the elected master switching device.
Step 202, based on the correspondence between the MAC address of the main control board included in the preset switching device and the device identifier of the network device running on the switching device, finding the target device identifier corresponding to the MAC address of the target main control board.
Referring to table 1, an example of a correspondence relationship between the MAC address of the main control board included in the switching device and the device identifier of the network device operating on the switching device is shown.
TABLE 1
Wherein, the MAC11 is a MAC address of the main control board 11 shown in fig. 1; MAC12 is the MAC address of the main control board 12; MAC21 is the MAC address of the main control board 21; MAC22 is the MAC address of the main control board 22; SDN1 is a device identifier of SDN controller 1; SDN2 is a device identification for SDN controller 2.
As can be seen from table 1, SW1 includes two main control boards with MAC addresses of MAC11 and MAC12, and an SDN controller with a device identifier of SDN1 runs on SW 1; similarly, the SW2 includes two main control boards with MAC addresses of MAC21 and MAC22, and an SDN controller with device identifier SDN2 runs on the SW 2.
In the present invention, as an embodiment, the correspondence may be preset in a network device, for example, preset in the SDN controller 1 and the SDN controller 2, then the step 202 is specifically that the network device searches for a device identifier (referred to as a target device identifier, which is called a target device identifier only for convenience of description, and is named only for convenience of description, and is not limited to this), corresponding to the MAC address of the target host board, from a correspondence between the MAC address of the host board included in the locally preset switching device and the network device operating on the switching device, for example, the MAC address obtained by the SDN controller 1 in the step 201 is MAC11, and then obtains the device identifier corresponding to the MAC11 as SDN1 by querying the table 1.
In the present invention, as another embodiment, the correspondence may be preset in any reachable server other than the network device, and the network device searches for the target device identifier corresponding to the MAC address of the target main control board through information interaction with the server, which may be specifically implemented by an implementation manner shown in the flow shown in fig. 3 below, which is not repeated here.
Step 203, if the target device identifier is the same as the device identifier of the network device, determining that the network device is a master network device.
As described above, the network device may find, in step 202, a target device identifier (a device identifier of the network device running on the main switching device) corresponding to the MAC address of the target main control board on the main switching device, so that, in this step 203, the network device may compare the found target device identifier with the device identifier of the device, and if the target device identifier and the device identifier are the same, determine that the network device is the main network device, that is, the network device is located on the main switching device, thereby achieving consistency between the main switching device and the main network device; if not, the network device can be determined to be the standby network device.
Thus, the flow shown in fig. 2 is completed.
As can be seen from the process shown in fig. 2, in the present invention, by presetting the correspondence between the MAC address of the main control board included in the switching device and the device identifier of the network device operating on the switching device, when the network device acquires the MAC address of the main control board located on the main switching device, the device identifier of the network device operating on the main switching device, which corresponds to the MAC address of the main control board located on the main switching device, can be found based on the correspondence, and if the device identifier of the network device operating on the main switching device found is the same as the device identifier of the network device itself, it is determined that the network device itself is the main network device, thereby achieving the consistency between the main switching device and the main network device.
The following describes specifically the step 202 of finding the target device identifier corresponding to the MAC address of the target main control board:
referring to fig. 3, there is provided a flowchart for implementing step 202 of the present invention. As shown in fig. 3, the process may include the following steps:
step 301, sending a query message to a server located outside the network device.
Inquiring the MAC address of the target main control board carried in the message; the server is preset with the corresponding relation between the MAC address of the main control board included by the switching equipment and the network equipment running on the switching equipment.
Step 302, receiving a response message returned by the server.
And the response message carries a target equipment identifier, wherein the target equipment identifier is the equipment identifier which is searched by the server and corresponds to the MAC address of the target main control board based on the preset corresponding relation between the MAC address of the main control board and the network equipment running on the switching equipment.
Step 303, acquiring the target device identifier carried in the response message.
The flow shown in fig. 3 is completed.
Through the process shown in fig. 3, the target device identifier corresponding to the MAC address of the target main control board is searched from the external server.
The method provided by the invention is described below by means of a specific embodiment:
the switching device shown in fig. 1 is still taken as an example. In this embodiment, the administrator presets the corresponding relationship shown in table 1 in a server (not shown in fig. 1). In addition, SW1 and SW2 have passed through master-slave election, with election SW1 being the master switch device and SW2 being the slave switch device.
After completing the master-slave election of the switching device, the master board 11 on the master switching device SW1 (here, the master board 11 is taken as an example) notifies the SDN controller 1 and the SDN controller 2 of its MAC address (MAC 11).
After acquiring the MAC11, the SDN controller 1 sends a query message to the server, which is recorded as Packet1, and Packet1 carries MAC 11.
The server obtains the MAC11 carried in Packet1, looks up table 1, and if the device identifier corresponding to MAC11 is SDN1, returns a response message to SDN controller 1, and records the response message as Packet2, and Packet2 carries SDN 1.
The SDN controller 1 obtains the SDN1 carried in the Packet2, and compares the obtained device identifier with the self device identifier (SDN1), so that the obtained device identifier is the same as the self device identifier, and thus, it is determined that the self is a master controller, that is, a master controller (SDN controller 1) running on the master switching device (SW 1).
Similarly, after acquiring the MAC11, the SDN controller 2 sends a query message to the server, where the query message is recorded as Packet3, and the Packet3 carries the MAC 11.
And the server inquires the table 1 according to the obtained MAC11, if the device identifier corresponding to the MAC11 is the SDN1, a response message is returned to the SDN controller 2 and is marked as Packet4, and the Packet4 carries the SDN 1.
The SDN controller 2 acquires SDN1 carried in Packet4, and compares the acquired device identifier with its own device identifier (SDN2), so that it is determined that it is a controller, that is, a controller (SDN controller 2) running on the standby switching device (SW 2).
This completes the description of the present embodiment.
