本文件规定了家庭集群系统的体系结构以及它们之间的互通。它指定了一个集群到集群接口，以实现家庭集群系统之间的互通和这些集群系统支持的应用程序之间的互操作性，以及这些集群系统应用程序的通用用户界面。该通用用户界面为用户信息交换提供输入和输出方法，以访问、监视和控制在家庭集群系统上运行的应用程序。

This document specifies an architecture for home cluster systems and for interworking among them. It specifies a cluster-to-cluster interface to enable interworking among home cluster systems and interoperability among the applications supported by these cluster systems as well as a common user interface to these cluster-system applications. This common user interface provides input and output methods for user information exchange to access, monitor and control applications running on home cluster systems.
