ISO/IEC 29341-4-11:20 11(E)描述了能够对A/V设备的流式传输能力进行建模以及在设备之间绑定这些能力的服务类型。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)。 该服务定义符合UPnP设备架构1.0版。本国际标准取代2008年发布的ISO/IEC 29341-4-11第一版，构成技术修订。

ISO/IEC 29341-4-11:2011(E) describes the service-type which 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).
This service definition is compliant with the UPnP Device Architecture version 1.0. This International Standard replaces ISO/IEC 29341-4-11, first edition, published in 2008, and constitutes a technical revision.
