摘要： A method of managing bandwidth allocation across a video pipe that delivers both streaming adaptive bitrate (ABR) content and progressive download ABR content includes receiving a designation of a congestion boundary within a video pipe, the congestion boundary designating a first percentage of the video pipe that is to be used for streaming ABR content when congestion exists on both sides of the congestion boundary, wherein a remaining percentage of the video pipe is to be used for progressive download ABR; allocating bandwidth for streaming ABR content, wherein the gateway device can allocate for streaming content only that portion of the remaining percentage of bandwidth that is not requested for progressive download content; and allocating bandwidth for progressive download content, wherein the gateway device can allocate for progressive download content only that portion of the first percentage of bandwidth that is not requested for streaming content.

摘要： A system and method in which each node in a Content Distribution Network (CDN) maintains information about the most-recent state of the CDN as a whole to decide what bandwidth to use when serving a content subscriber so that the total bandwidth of the entire multimedia content streamed/delivered to the subscriber through various nodes in the CDN remains within a pre-defined bandwidth cap for the subscriber. The entire CDN is thus treated as a single edge node. Each node in a CDN may periodically transmit to all other nodes in the CDN, information about any activity that occurs at the transmitting node. Instead of reporting to all the nodes, the transmitting node may report details of its node-specific activity to a subset of “interested” nodes. Once each node has a model of what the entire CDN system is currently doing, that node can implement bandwidth management in a coherent manner.
摘要翻译：一种系统和方法，其中内容分发网络（CDN）中的每个节点维护关于CDN的最新状态的信息作为整体，以决定在为内容订户服务时使用什么带宽，使得整个多媒体的总带宽通过CDN中的各个节点流/传送给订户的内容保持在订户的预定义带宽上限内。因此，整个CDN被视为单个边缘节点。 CDN中的每个节点可以周期性地向CDN中的所有其他节点发送关于在发送节点处发生的任何活动的信息。代替向所有节点报告，发送节点可以将其节点特定活动的细节报告给“感兴趣”节点的子集。一旦每个节点具有整个CDN系统当前正在做什么的模型，该节点可以以一致的方式实现带宽管理。

摘要： Some embodiments are directed to a method performed by a pipe control node for managing network resources that are used to transport network traffic. The method includes allocating network resources to a virtual pipe for transporting a plurality of multimedia streams through the network. Utilization of the network resources by the plurality of multimedia streams transported through the virtual pipe is monitored relative to the network resources allocated to the virtual pipe. The network resources that are used by the plurality of multimedia streams transported through the virtual pipe are managed in response to the monitored utilization. Some other embodiments are directed to a corresponding pipe control node that manages network resources which are used to transport network traffic.

摘要： A method, Over-The-Top (OTT) content provider server, Content Delivery Network (CDN) Redirector server, and CDN delivery server for managing bandwidth while delivering electronic content utilizing OTT adaptive streaming to a plurality of client devices at a customer premises. The OTT content provider server receives client device priorities from a customer and stores in a customer profile, a device weighting for each of the plurality of client devices. The OTT content provider server also stores an indication of an available bandwidth of a premises connection at the customer premises. When each client device requests OTT content, a delivery server in a CDN allocates a bitrate for the requesting client device based on the available bandwidth for the premises connection and the device weighting of the requesting client device, and delivers the requested OTT content to the requesting client device at the allocated bitrate.

摘要： A system and method for effectuating fast channel change in an adaptive streaming environment. A plurality of adjacent channels may be predicted relative to a current streaming channel engaged by a client device. Upon prioritizing the adjacent channels, the client device may be configured to pre-fetch metadata and initialization information for a subset of the prioritized adjacent channels based on bandwidth conditions, video player buffer status, etc. When a channel is changed, the client device is operative to use the pre-fetched data to quickly obtain encoded media content at a select bitrate for rendering.

摘要： A scheme for providing targeted advertisements in a multicast adaptive bitrate (ABR) streaming environment. In one implementation, ads specific to a subscriber's demographic profile and relevant to the genre of a tuned MABR media channel may be downloaded in a gateway (GW) or into a network storage system. In another implementation, multicast ABR streams of ads may be triggered at specific points (e.g., insertion markers in a multicast ABR media channel) that can be selectively joined by a GW node based on demographics and channel genre. In yet another implementation, continuously streaming multicast ad channels may be switched at suitable points in a multicast ABR media channel based on targeting parameters.
