Abstract
The paper presents a set of experiments on real time protocols using the ORCHESTRA software fault injection environment. The paper first describes a specific implementation of ORCHESTRA for testing applications that use Unix sockets for communication. A novel feature of this tool is that it utilizes operating system support provided by Real Time Mach to quantify and compensate for the intrusiveness of the fault injection mechanism. The fault injection experiments which are described, tested fault tolerance and timing behavior of two target real time protocols. In addition, timing intrusiveness of ORCHESTRA was measured during the course of these experiments.
本文介绍了一套基于ORCHESTRA软件故障注入环境的实时协议实验。本文首先描述了用于测试使用Unix套接字进行通信的应用程序的ORCHESTRA的具体实现。该工具的一个新颖特性是，它利用Real Time Mach提供的操作系统支持来量化和补偿故障注入机制的侵入性。本文所描述的故障注入实验，测试了两种目标实时协议的容错和定时行为。此外，在实验过程中测量了ORCHESTRA的定时侵入性。
