提供与可靠性和真实的时间相关的增强的服务质量（QoS）保证的通信服务对于分布式系统中的许多应用是重要的。本文介绍了实时可靠（RTD）的渠道，面向通信的抽象，可以配置，以满足各种分布式应用的QoS要求。这种定制能力基于使用CactusRT，CactusRT是一种支持从称为微协议的软件模块构建中间件服务的系统。每个微协议实现不同的语义属性或属性变体，并使用CactusRT运行时系统支持的事件驱动模型与其他微协议交互。除了RTD通道CactusRT和它的实施进行了说明。该原型在运行OpenGroup/RI MK 7.3 Mach实时操作系统和CORDS（一种基于x内核构建网络协议的系统）的Pentium PC集群上执行。
Communication services that provide enhanced Quality of Service (QoS) guarantees related to dependability and real time are important for many applications in distributed systems. This paper presents real-time dependable (RTD) channels, a communication-oriented abstraction that can be configured to meet the QoS requirements of a variety of distributed applications. This customization ability is based on using CactusRT, a system that supports the construction of middleware services out of software modules called micro-protocols. Each micro-protocol implements a different semantic property or property variant and interacts with other micro-protocols using an event-driven model supported by the CactusRT runtime system. In addition to RTD channels CactusRT and its implementation are described. This prototype executes on a cluster of Pentium PCs running the OpenGroup/RI MK 7.3 Mach real-time operating system and CORDS, a system for building network protocols based on the x-kernel.
