Problems solved by technology

In this case, when the task of the intelligent software module is busy, the optical path configuration, alarm, performance and other tasks to be processed by the host software module will be preempted for a long time. The query result returns overtime, causing the user to feel that the device is down; on the other hand, it will cause the optical path alarm, performance and other maintenance information reported on the board to not be responded in time, and even cause the loss of these information, making it difficult to locate the fault, etc. question

Embodiment 1

[0059] This embodiment mainly describes the method for starting the system of the intelligent optical network equipment with dual CPUs. Wherein, the executable file of the host software to be executed by the main CPU and the executable file of the intelligent software to be executed when the slave CPU is started are all stored in the peripheral FLASH located on the main control board of the intelligent optical network device.

[0060] The following steps will be performed when an intelligent optical network device starts up:

[0061] 101. The basic input and output system (BIOS) of the main CPU starts, copies the executable file of the host software stored in the FLASH to its own memory, and guides the main CPU to run the executable file of the host software in the memory.

[0062] 102. The master CPU reads the executable file of the smart software from the FLASH, and the host software decompresses the executable file of the smart software and copies it to the memory of the sl...

Embodiment 2

[0067] This embodiment mainly illustrates how an intelligent optical network device with dual CPUs maintains state synchronization between the two CPUs during operation.

[0068] Although the host software and the intelligent software run in their respective tasks, the host software and the intelligent software can communicate with each other through the Ethernet interface between the CPUs, so that even if the host software and the intelligent software run on different CPUs , the state synchronization between the two software is basically the same as the situation running on the same CPU, but the original communication between tasks under a single CPU is changed to Ethernet communication between different CPU systems, and this The difference can be shielded by the underlying communication module of the system, but the upper layer software basically remains unchanged. Therefore, during operation, the two CPU systems of the intelligent optical network device with dual CPUs can p...

Embodiment 3

[0070] This embodiment mainly illustrates how an intelligent optical network device with dual CPUs maintains configuration synchronization between the two CPUs during operation.

[0071] Usually, intelligent software needs to store some of its own configuration data in the peripheral FLASH located on the main control board, so that the stored configuration data can be correctly restored when it is reset next time. Since the slave CPU cannot directly access the FLASH peripherals, in this embodiment, the slave CPU reads and writes the FLASH through the master CPU. The specific method includes: the intelligent software sends the new configuration data to the host software through the Ethernet interface between the CPUs through the Ethernet message; the host software writes the received configuration data of the intelligent software into the FLASH. And when the intelligent software wishes to restore the configuration data stored by itself, it also needs to read the configuration d...

Abstract

The invention discloses an intelligent optical path network device with dual CPU and implementation method thereof. The intelligent network device includes: a network manager, a veneer, a main CPU and a slave CPU, wherein the main CPU calculates the cross connection based on the cross connection information in the configuration information sent by the network manager, and sends it to the veneer, the slave CPU calculates the cross connection based on the cross connection information in the configuration information sent by the network manager or the optical path topology state and / or optical path alarm information, and sends it to the veneer via the main CPU. According to the invention, two CPU systems are arranged in the intelligent optical path network device to operate the host computer software and intelligent software, which effectively solves the problem that the host computer software can not respond the commond of manager or maintenance information sent by the veneer in time due to the CPU resource preemption of intelligent software when the job is busy, therefor greatly enhancing the processing ability of the intelligent optical path network device.

Description

technical field [0001] The invention relates to the technical field of intelligent optical network, in particular to an intelligent optical network device with dual central processing units (CPUs) and its realization method. Background technique [0002] With the development of the Optical Transport Network (OTN) and the further expansion of the network scale, operations such as network transmission, management and protection of services have become very complicated. However, existing traditional optical transport networks such as Synchronous Digital Hierarchy (SDH) can only transmit and manage services by configuring specific connection information station by station, and the protection of services is limited to ring protection and chain protection. , so it has been unable to meet the needs of the rapid growth of business and network scale. In this case, the intelligent optical network emerges as the times require, and has become a development trend of the optical transpor...
