3## Introduction<a name="section11660541593"></a>
4
5Distributed Scheduler is used for cross-device component management. It allows the local device to access or control remote components, and enables app collaboration in distributed scenarios. Its main functions are as follows:
6
7-   Remote ability startup: Starts an ability on a remote device.
8-   Remote ability migration: Migrates an ability to a remote device.
9-   Remote ability binding: Binds an ability on a remote device.

9
10分布式组件管理部件模块负责跨设备组件管理，提供访问和控制远程组件的能力，支持分布式场景下的应用协同。主要功能如下：
11
12-   远程启动元能力：跨设备拉起远端设备上的指定元能力，并支持含界面元能力结束时回传数据。
13-   远程迁移元能力：将元能力跨设备迁移到远端设备。
14-   远程绑定元能力：跨设备绑定远端设备上的指定元能力。
15-   远程Call调用：获取远端指定通用组件的Caller通信接口，进行跨设备调用指定通用组件。
