example 1

[0048] In this example, the line card discards all data packets received on the port connected to the standby main control board.

[0049] When the line card code is initialized, the slots of the active and standby main control boards are detected, the port connected to the active main control board is set to receive normally, and the port connected to the standby main control board is set to discard all received packets. The sending status of the two groups of ports connected to the active and standby main control boards is normal.

[0050] image 3 It is a flow chart of the switchover of the active and standby main control boards (setting the packet receiving state of the line card port) according to Example 1 of the embodiment of the present invention, such as image 3 As shown, the process is as follows:

[0051] When the master / standby switchover occurs, the line card generates an interrupt signal of the operating system. In the interrupt service program or interrupt pr...

example 2

[0056] In this example, the standby main control board only performs MAC address learning on the port connected to the line card, but does not forward data packets.

[0057] When the main main control board is initialized or running the spanning tree protocol, the port connected to the line card is set to the forwarding state, and when the standby main control board is initialized or running the spanning tree protocol, the port connected to the line card is set to the learning state , the port in the learning state only learns the MAC address, but does not forward the data packet. This ensures that the line card receives only one packet. And the standby main control board can learn the MAC address. After the line card has passed this setting, it can only receive packets from the active main control board, but cannot receive packets from the standby main control board.

Embodiment 1

[0064] This device embodiment corresponds to the first example above, and according to an embodiment of the present invention, a line card is provided, Figure 5 is a structural block diagram of a line card according to Embodiment 1 of the device of the present invention, as shown in Figure 5 As shown, the structure includes: a sending module 52 and a receiving module 54, and the structure will be described in detail below.

[0065] The sending module 52 is configured to send data to the main control board in the active state and the main control board in the standby state during data interaction with the main control board in the active state and the main control board in the standby state. The same data, wherein the line card is connected to the main control board in the active state and the main control board in the standby state; the receiving module 54 is used to receive data from the main control board in the active state; the receiving module 54 is also It is used to ...

Abstract

The invention discloses a data processing method based on the operating / standby switch of master control boards, a line card and the master control boards. The method comprises the following steps: in the process of carrying out data exchange between the line card and the master control board in operating mode as well as the master control board in standby mode, the line card sends the same data to the master control board in operating mode and the master control board in standby mode, and receives the data from the master control board in operating mode, wherein the line card is connected to the master control board in operating mode and the master control board in standby mode; when the master control board in operating mode and the master control board in standby mode are switched, the line card receives the data from the master control board which is switched from standby mode to operating mode. Through the invention, the performance of operating / standby switch of a system can be improved, and the customer satisfaction is increased.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data processing method based on switching of a main control board, a line card and a main control board. Background technique [0002] In communication equipment, in order to improve the reliability of the equipment, the main control board often adopts the active and standby mechanism. When the main main control board, which can also be referred to as the main control board in active state (for example, denoted as No. 1 main control board), fails, the service control and service forwarding are switched to the standby main The main control board in the standby state (for example, it is recorded as No. 2 main control board), and the state of the standby main control board becomes the active main control board, and the state of the original active main control board becomes the standby main control board. During the master / standby switchover process, the service forwarding is sw...
