    • A network architecture for a network of electronic devices includes a device layer having a plurality of electronic devices interconnected using a network backbone, wherein the plurality of electronic devices each operate using a device native communication protocol. The architecture also includes a device abstraction layer (DAL) which communicates with each of the devices using the device native communication protocols and also presents a unified communication interface to a content abstraction program interface. The content abstraction program interface communicates with the device layer through the unified communication interface of the DAL and includes a set of content services for controlling content on the network. In one embodiment the content abstraction program interface includes a content location system (CLS), a content change notification system (CCNS), and a content engagement system (CES).
    • 用于电子设备网络的网络架构包括具有使用网络主干互连的多个电子设备的设备层,其中所述多个电子设备各自使用设备本地通信协议进行操作。 该架构还包括使用设备本地通信协议与每个设备通信的设备抽象层(DAL),并且还向内容抽象程序接口呈现统一的通信接口。 内容抽象程序接口通过DAL的统一通信接口与设备层通信,并且包括一组用于控制网络内容的内容服务。 在一个实施例中,内容抽象程序接口包括内容定位系统(CLS),内容改变通知系统(CCNS)和内容参与系统(CES)。
