摘要： Content delivery by a network node is optimized. The network node is communicatively coupled between multiple end user devices and at least one content service provider. A request for a media streaming service available from the content service provider is intercepted from a first requestor device. It is determined if the media streaming service is registered for delivery optimization based on at least one service rule specific to the media streaming service. It is determined if a second requestor device is currently receiving the media streaming service from the content service provider. In response to the media streaming service being received by the second requestor device, delivery optimization of the media streaming service is performed by replicating the media streaming service for delivery to the first requestor device. The replicated media streaming service is sent to the first requestor device.

摘要： Content delivery by a network node in a network is optimized. The network node is communicatively coupled between multiple client devices and at least one content service provider. A media streaming service provided by a content service provider is received at the network node over a first unicast link. The service is transmitted from the network node to a first requestor device via a second unicast link. A request from a second requestor device for the service is intercepted by the network node. If it is determined that a multicast optimization threshold has been reached and/or exceeded, the service is transmitted from the network node to the first and second requestor devices using a single multicast link, while the service is received from the content service provider over the first unicast link.
摘要翻译： 通过网络中的网络节点进行内容传送进行了优化。 网络节点通信地耦合在多个客户端设备和至少一个内容服务提供商之间。 由第一单播链路在网络节点处接收由内容服务提供商提供的媒体流服务。 该服务经由第二单播链路从网络节点传送到第一请求者设备。 来自第二请求者设备的针对服务的请求被网络节点拦截。 如果确定已经达到和/或超过了组播优化阈值，则使用单个多播链路将服务从网络节点传送到第一和第二请求者设备，而从内容服务提供商通过 第一个单播链路。
