摘要
板级软件是实现高速路由器线路接口卡功能的重要基础,本文根据POS接口数据处理过程和系统控制需求分析核心路由器中8×155M POS线卡板级软件所需要实现的功能,并进行详细的模块划分。根据该软件功能复杂且功能并发性强的特点,本文将各个模块采用VxW orks操作系统中的实时任务来实现,并给出其中关键模块的设计和实现方法。本文的研究成果已经在核心路由器中得到实现,软件满足系统处理的需求且运行稳定可靠。
Board-level software is the foundation on the design of router linecards in high-speed reuters. Based on the characteristics of the data processing procedure and requirements of the system controlling, this paper analyzes the function of the board-level software of 8 × 155M POS linecard and divides it into several modules. For the complication and inner high concurrence of the modules, this paper chooses real time tasks in VxWorks to implement the modules, and it also provides the design and implementation of the key modules. The achievements of this paper have been used in the core router and the results show that software runs constantly can meet the requirements of the system.
