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。
The board-level software is an important foundation for implementing the high-speed router line interface card function. According to the POS interface data processing and system control requirements, this paper analyzes the functions required by the 8 × 155M POS line card-level software in the core router and performs detailed module Divided. According to the complexity of the software and the strong concurrency of functions, this paper uses the real-time tasks in the VxW orks operating system to implement each module, and gives the design and implementation of the key modules. The research results of this paper have been implemented in the core router. The software meets the needs of system processing and runs stably and reliably.
