In the medical domain, new developments commonly rely on client/server architectures. But face to distributed environments, the software developers encounter a tremendously increasing complexity when building integrated applications. This paper presents the HELIOS Unification Bus (HUB), a communication integration framework for the HELIOS medical software engineering environment that allows the exchange of data between components that can be hosted on heterogeneous machines linked by a network. The HUB is developed as a C++ toolbox over UNIX and TCP/IP. It includes a message routing entity called router and a generic application programming interface (API), implemented as a C++ library, that allows to build easily software components compliant with the standardised HELIOS language. Messages conveyed by the bus are composite objects that are serialized to be transmitted over the bus using the ASN.1 ISO presentation protocol. The article describes the use of the bus to ease the development and execution of distributed medical applications and its role from the communication integration standpoint.
在医学领域，新的发展通常依赖于客户机/服务器架构。但面对分布式环境时，软件开发人员在构建集成应用程序时会遇到极大增加的复杂性。本文介绍了HELIOS统一总线（HUB），这是一种用于HELIOS医学软件工程环境的通信集成框架，它允许在通过网络链接的异构机器上托管的组件之间交换数据。HUB是作为一个基于UNIX和TCP/IP的C++工具箱开发的。它包括一个称为路由器的消息路由实体和一个通用应用程序编程接口（API），该接口作为一个C++库实现，允许轻松构建符合标准化HELIOS语言的软件组件。总线上传输的消息是复合对象，这些对象被序列化以便使用ASN.1 ISO表示协议在总线上传输。本文描述了使用该总线来简化分布式医学应用程序的开发和执行，以及从通信集成角度来看它的作用。
