ISO/IEC 29341-20-11:20 17符合UPnP设备架构1.0版[14]。 这种服务类型使得能够对A/V设备的流式传输能力进行建模，并在设备之间绑定这些能力。能够根据UPnP AV架构发送或接收流的每个设备将具有ConnectionManager服务的1个实例。该服务为控制点提供了一种机制，用于: a)在源/服务器设备和接收器/渲染器设备之间执行能力匹配， b)查找关于网络中当前正在进行的传输的信息， c)建立和拆除设备之间的连接(当流协议需要时)。 ConnectionManager服务足够通用，可以适当地抽象不同类型的流机制，例如基于HTTP的流、RTSP/RTP-基于和基于1394的流。 ConnectionManager使控制点能够在建立连接时从物理介质互连技术中抽象出来。术语？本服务模板中使用的“流”是指模拟和数字数据传输。

ISO/IEC 29341-20-11:2017 is compliant with the UPnP Device Architecture version 1.0 [14].
This service-type enables modeling of streaming capabilities of A/V devices, and binding of those capabilities between devices. Each device that is able to send or receive a stream according to the UPnP AV Architecture will have 1 instance of the ConnectionManager service. This service provides a mechanism for control points to:
a) Perform capability matching between source/server devices and sink/renderer devices,
b) Find information about currently ongoing transfers in the network,
c) Setup and teardown connections between devices (when required by the streaming protocol).
The ConnectionManager service is generic enough to properly abstract different kinds of streaming mechanisms, such as HTTP-based streaming, RTSP/RTP-based and 1394-based streaming.
The ConnectionManager enables control points to abstract from physical media interconnect technology when making connections. The term?stream' used in this service template refers to both analog and digital data transfer.
