Problems solved by technology

[0008] No matter which of the above situations occurs, the standby MPU will eventually fail to start, and the frame where the standby MPU is located, such as the LCC, will also fail to start.
Similarly, other single boards such as SFU or LPU will also fail to start the standby MPU

[0053] see image 3 , image 3 The flow chart is implemented for the first embodiment provided in this application. Such as image 3 As shown, the process may include the following steps:

[0054] Step 301 , during the startup process of the designated board, the active MPU sends locally stored system resource status information (denoted as system resource status information 300 ) to the designated board.

[0055] As described in the background technology, the active MPU locally stores a lot of system resource status information, which cannot be sent to the specified board at one time. Based on this situation, the active MPU will split the locally stored system resource status information sent. Assume that the system resource status information sent this time in step 301 is recorded as system resource status information 300 .

[0056] Step 302 , the active MPU detects whether the active MPU successfully sends the system resource status information 300 , if not, execute st...

[0071] see Figure 4 , Figure 4 The flow chart is implemented for the second embodiment provided in this application. Such as Figure 4 As shown, the process may include the following steps:

[0072] Step 401 , during the startup process of the designated board, if the active MPU successfully sends all the locally stored system resource status information to the designated board, then sends a system resource status information backup completion message to the designated board.

[0073] Step 402 , the active MPU detects whether the active MPU has successfully sent the system resource state information backup completion message, if not, execute step 403 , and if yes, execute step 407 .

[0074] The active MPU will call a sending interface function when sending the system resource status information backup completion message. When the sending is successful, the sending interface function will return a receipt indicating that the sending is successful. When the sending fails, ...

Abstract

The invention relates to a single board starting control method and a single board starting control device. According to the invention, an information retransmission mechanism is additionally arrangedin a cluster, and a starting protection mechanism is additionally arranged on a to-be-started single board. Based on the above two mechanisms, the starting failure probability of the single board canbe reduced. The starting failure probability of frames with the single board, such as LLC and the like, can be further reduced.

Description

technical field [0001] The present application relates to network communication technology, in particular to a single-board start-up control method and device. Background technique [0002] The main control board processing units (MPU: Main Process Unit, referred to as the main control board) of different frames are connected through optical fibers to form a unified system (also called a cluster). In a cluster, the MPU of one frame is elected as the active MPU (Master for short), and the MPUs of the remaining frames are the standby MPUs (Slave for short). figure 1 It shows a cluster composed of one central chassis (FCC: Fabric Central Chassis) and two line card chassis (LCC: Line Card Chassis) connected by optical fibers. exist figure 1 In the FCC, the MPU in the FCC and the MPUs in the two LCCs are connected through the control connection unit (CCU: Control Connection Unit) in the FCC using optical fibers. ), and a switching fabric chip unit (SFU: Switch Fabric Unit, ref...
