DECnet软件的剖析、评价、优化及剖析方法

Analysis,Evaluation and Optimization to DECnet Software, and the Software Analysis Method

摘要: 本文首先详细剖析了第二版本的RSX/IAS DECnet源程序的总体结构、核心成分(CEX和AUX)、通信设备驱动程序、数据通信处理程序(DCP)及网络生成和管理成分,阐明了DECnet软件和操作系统的关系,DECnet软件的实现技术、调度算法、各模块的数据结构及实现算法,在此基础上,对DECnet软件进行了评价、优化,并将软件的剖析、评价、优化容为一体,形成了一种大型软件系统的剖析方法。

Abstract: Firstly, this paper analyses the total structure, kernel parts(CEX and AUX), communication device driver, data communication program(DCP), network generation and management parts of RSX/IAS DECnet source programs(V2.0) in detail,and expounds the relations between DECnet software and operating system, realization techniques of DECnet, dispatch algorithms, data structures and realization algorithms of every module. Secondly, the paper gives the evaluation and optimization to DECnet software, and puts forwards a software analysis method by means of unitying the analysis, evaluation and optimization of the software.
