ASN.1支持工具的设计与实现

Design and Implementation of ASN.1 Support Tool

本文分析了国外已有的ASN.1支持工具所采用的两种编译方法、它们的特点以及在应用中的局限性;讨论了笔者实现的CICA ASN.1工具的设计思想、总体结构及其实现。CICA ASN.1支持工具吸收了国外两类系统的优点,弥补了两类系统在应用上各自的缺陷。

This paper discusses the design and implementation of ASN.1 (Syntax Notation One) support tool.The merits and shortcomings of two typical approaches in realization of an ASN.1 compiler are analysed.One of them translates an ASN.1 module into a tree-like internal representation and the other into the source codes of a programming language.The author combined the two approaches in an elegant one in the development of ASN.1 tool.As a result,it is not only suitable for protocol implementation,but also suitable for protocol testing.
