With the transformation of Internet from research network to commercial network and the emergence of allkinds of applications, which have different QoS needs,Internet is strongly required to provide QoS service. This papercompares the two solutions: Interserv and Diffserv and makes a brief introduction on Diffserv. Then based on these,software architecture of Diffserv router is ourlined and some critical function modules are discussed in detail. At theend of the paper we discuss the future work which should be done on Diffserv router.

精细分析对提高关键软件的安全非常重要,并因计算量大而需要自动化.本文基于J M Voas的Fault/Failure概念模型及其PIE分析,提出一个实用的软件代码精细分析技术和工具.文中描述了软件代码精细分析的全过程,重点讲述“自动分析记录”的工作流程及执行、感染和传播这三个关键分析的概念性算法,并给出了工具的框架图解.此外还提出粒度可调思想,能调节分析的精度和范围,较好地解决了Fault/Failure模型的限制,拓展了用途.最后本文给出了一些具体的应用思路,如放置警报器、评估可靠性、配置资源、设计测试实例等,以及对面向对象软件测试的启发.
