PROGRAM DOWNLOAD IN A NETWORK

摘要

A configuration infrastructure that allows computing devices to dynamically bootup and attach to a multimedia network domain. The configuration infrastructure includes a centralized domain configuration tree for organizing and sharing the default domain configuration, management and control information in a uniform and consistent manner; a domain directory service that publishes and retrieves the configuration information and registers any devices attached to the domain; a set of local configuration trees (one per device) that allow to cache the device configuration settings and remember the customized configuration attributes; a general design template for building software controllers so that they can be integrated with our configuration infrastructure; a general protocol for enabling controller-to-controller negotiation and delegation; a software distribution and downloading service for remote installation of controllers and system components; a watchdog controller that continually monitors the location and state of attachment of the client; and a control and monitoring system for the bootup and attachment processes.
