Embodiment 1

[0035] The method provided in Embodiment 1 of the present invention is applied to a distributed network device, and the control channel of the distributed network device is as follows: figure 1 shown. image 3 The method provided by Embodiment 1 of the present invention is shown.

[0036] see image 3 , image 3 It is a flowchart of the method provided by Embodiment 1 of the present invention. Such as image 3 As shown, the process may include the following steps:

[0037] Step 301, the main CPU receives a detection trigger sent by any non-main CPU, and sends a detection message carrying the first serial number to the non-main CPU through the main control channel to the non-main CPU;

[0038] In this step 301, the detection trigger is realized by the non-main CPU sending a detection start message to the main CPU when initially returning to normal (NORMAL). The main CPU starts to send a detection message to the non-main CPU for detection after receiving the detection trig...

Embodiment 2

[0063] see Figure 5 , Figure 5 The flow chart of the method provided in Example 2. As mentioned above, this process is applied to the above-mentioned distributed system, specifically including Figure 5 Steps shown:

[0064] Step 501, select a main CPU on a distributed network device from the distributed system as the main CPU of the system.

[0065] Step 502, when the main CPU of the distributed network device is selected as the main CPU of the system, send a detection message carrying the serial number 1 to the non-system main CPU through the main control channel to the non-system main CPU, and send the detection message to the non-system main CPU. Receive the response message carrying the sequence number 2 replied by the non-system main CPU within the first set time of the message, compare whether the sequence number 2 carried in the response message is consistent with the sequence number 1, if not, then Determine that the main control channel from the system main CPU...

Abstract

The invention provides a control channel fault determining method and device. In one method, whether the control channel between a non-main CPU (central processing unit) and a main CPU fails is determined by detecting with a bidirectional awarding detecting mechanism carrying a serial number, and the fault type is further determined according to the answer message returned by the non-main CPU at the time of determining the fault of the control channel between the non-main CPU and the main CPU.

Description

technical field [0001] The invention relates to network communication technology, in particular to a control channel fault determination method and device thereof. Background technique [0002] In network communication, a typical distributed network device structure such as figure 1 As shown, it includes at least the following boards: main control board, line card board, switching fabric board and backplane. Among them, the main control board, the line card board, and the switching network board all contain at least one CPU. The Main CPU on the main control board is elected as the main CPU of the distributed network device, and the remaining CPUs are used as non-main CPUs. The link between the non-primary CPUs is called the control channel, figure 1 Control channel is shown. [0003] The control channel is used to complete the relevant functions of the control plane of the entire distributed network equipment. If there is a failure, it will definitely affect the operation...
