PTN (Packet Transport Network) device of which line cards automatically adapt and download software and method

Abstract

The invention discloses a PTN (Packet Transport Network) device of which line cards automatically adapt and download software and a method relates to the field of maintenance and management of PTN device line card software. The PTN device comprises a master control cross panel and a plurality of line cards. The master control cross panel comprises a layer 2 exchange module and a master control CPU buckle. The line cards comprise line card CPU buckles and coding modules. One end of the layer 2 exchange module is connected with a plurality of line card CPU buckles, and the other end is connected with the master control CPU buckle. The plurality of line card CPU buckles establish communication connection with the master control CPU buckle. The line card CPU buckles download universal platform software from the master control CPU buckle. After the universal platform software is started, the line card CPU buckles automatically download line card special software from the master control CPU buckle according to panel type codes. According to the device and the method, the line cards can automatically download the software required by operation, manual intervention is avoided, the production efficiency and accuracy are improved, and the upgrading, maintenance and management of the line card software are facilitated.

Description

technical field [0001] The invention relates to the field of maintenance and management of line card software of PTN (Packet Transport Network, packet transport network) equipment, in particular to a PTN equipment and method for automatically adapting line cards and downloading software. Background technique [0002] Existing PTN equipment generally includes components such as a backplane, a main control module, a crossover module, and a line interface module. Wherein, the main control module and the cross-connect module are combined to form a main control cross-connect board, and the line interface modules are each line card in the device. Generally, the main control cross-connect board and each line card have their own CPUs, and the CPU is plugged into a single board in the form of a sub-board. The CPU sub-board of each single board is used to implement the control and management functions of the board. Usually, all line cards use the same type of subboard. Depending on t...

Problems solved by technology

This single access mode leads to a large demand for PCs in the downloading process during mass production of equipment, which requires a large area of ​​space, long waiting time for invalidation, and low production efficiency.

[0005] (2) Different line cards require different software to be downloaded. It is necessary to manually distinguish the type of single disk, and download the corresponding program according to the type of single disk. There are many human-computer interactions, high error rates, and high requirements for the quality of the staff.

[0007] (4) Once the program is updated, it is necessary to update the software for each line card operation, which is not conducive to the upgrade, maintenance and management of the line card software
