Embodiment 1

[0058] Embodiment 1 (normal soft reset: triggered by the user)

[0059] Such as image 3 Shown is the flow chart of embodiment one, image 3 It is a process flow of a configuration method of a service board in an embodiment of the present invention Figure II , the main purpose of which is to implement the method of configuring service boards in the scenario where the user triggers a CPU reset, so as to realize non-interruption of services. The method mainly includes the following steps:

[0060] Step 301, notify the CPU of power-off reset;

[0061] The current equipment is running normally, customer business traffic is normally forwarded, and business configuration data is written into the data storage device in real time; the user sends a service single-board power management device for a certain slot through the network management or command line.

[0062] Step 302, CPU power off and reset;

[0063] The power management device of the service board notifies the CPU soft...

Embodiment 2

[0071] Embodiment 2 (the service board process is abnormal during soft reset)

[0072] Such as Figure 4 Shown is embodiment two of the present invention, as Figure 4 Shown is the flow chart of embodiment two, Figure 4 It is a process flow of a configuration method of a service board in an embodiment of the present invention Figure three , its main purpose is to realize the method of configuring service boards in the CPU reset scenario triggered by software exceptions. It can find the abnormality of its own process on the service boards, and restore the normal operation of the software on the CPU through CPU resets, achieving Business non-interruption purposes. Specifically, it mainly includes the following steps:

[0073] Step 401, the CPU software abnormally stops the watchdog and resets the CPU;

[0074] The current equipment is running normally, the customer’s business traffic is forwarded normally, and the business configuration data is written into the data stora...

Embodiment 3

[0081] Embodiment 3 (CPU hardware exception of service board due to abnormal soft reset)

[0082] Such as Figure 5 Shown is embodiment three of the present invention, as Figure 5 Shown is the flow chart of embodiment three, Figure 5 It is a process flow of a configuration method of a service board in an embodiment of the present invention Figure four The main way is to realize that when the control board detects that the CPU of the service board cannot respond to any processing request, the control board triggers the reset of the CPU of the service board through the power management of the service board, and configures the method of the service board to restore the normal operation of the CPU. A non-disruptive approach. Specifically, it mainly includes the following steps:

[0083] Step 501, notify the CPU of power-off reset;

[0084] The current equipment is running normally, the customer business traffic is forwarded normally, and the business configuration data is ...

Abstract

The embodiment of the invention discloses a configuration method of a service single board. The method comprises the following steps that: a first service general configuration of a service hardware chip of the service single board is backed up; under the condition that a CPU (Central Processing Unit) is reset, the service processing hardware chip works normally; after resetting initialization ofthe CPU is completed, the CPU acquires the first service general configuration; the CPU acquires a second service general configuration from a control single board; the CPU compares with the first service general configuration with the second service general configuration; the CPU integrates and acquires service forwarding chip configuration data according to a comparison result; and the CPU configures the service hardware chip according to the service forwarding chip configuration data. The problem of long-time interruption of a customer service flow due to the resetting of the CPU of the service single board in the related art is solved; the service forwarding interruption time is substantially shortened in the CPU resetting process, and even non-interruption service forwarding can be realized; and therefore, the stability and the availability of the service single board are improved, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a service single board and a configuration method. Background technique [0002] In the bearer network equipment, customer communication service traffic is forwarded by the service board, and the forwarding is required to be uninterrupted for 7*24 hours. The service board is composed of service processing hardware chips and CPU (Central Processing Unit) and other components. Among them, the service processing hardware chip is used for service traffic forwarding, and the software running on the service board CPU is used to configure the service chip and participate in the protocol processing process of some services, such as ARP (Address Resolution Protocol) protocol, BGP (Border Gateway Protocol) protocol, etc. [0003] The service configuration process of the service board is generally as follows: the user configures the service to the control board software through the ...
