摘要： A tracker application server (AS) instructs a content cache server (CCS) to join a peer-to-peer (P2P) swarm based on the status of the P2P swarm. The tracker AS determines whether to invite a CCS to join the P2P swarm be based on an underlying network condition change, a peer node joining or leaving the P2P swarm, change(s) in traffic condition, location, capability or workload of the peer node(s) in the swarm. The tracker AS sends an invitation message to the CCS, indicating the content of interest and a peer list identifying the peer nodes of the P2P swarm. Upon receiving the invitation message from the tracker AS, the CCS sends a response to the tracker AS. Upon receiving a response indicating the acceptance of the invitation, the tracker AS puts the CCS into the P2P swarm, and the CCS joins the swarm using a P2P protocol.
摘要翻译：跟踪应用服务器（AS）根据P2P群的状态指示内容缓存服务器（CCS）加入对等（P2P）群。跟踪器AS基于底层网络状况变化，对等节点加入或离开P2P群组，决定是否邀请CCS加入P2P群组，改变对等节点的流量状况，位置，能力或工作量（s）在群中。跟踪器AS向CCS发送邀请消息，指示感兴趣的内容和标识P2P群的对等节点的对等体列表。在从跟踪器AS接收到邀请消息时，CCS向跟踪器AS发送响应。跟踪器AS收到指示接受邀请的响应后，将CCS放入P2P群中，CCS使用P2P协议加入群组。

摘要： Embodiments contemplate the movement of mobile node (MN) from a first access network to a second access network, while in communication with a CDN server (e.g. a surrogate providing a multimedia streaming session). The server selection may become sub- optimal as a result of this movement. A first CDN may learn about MN mobility event via the MN, an access network node, the server, or another node. The first CDN may trigger reselection by upstream CDN by sending a CDNI reselection request message, including information for the upstream CDN to perform request routing for the MN with the specified content, at a different location. The upstream CDN may perform the request routing procedure. The upstream CDN may return the request routing result to first CDN. The initial server may send a redirection message back to the application, which may interpret the message and continue streaming from a different server.
摘要翻译：实施例考虑移动节点（MN）从第一接入网络移动到第二接入网络，同时与CDN服务器（例如提供多媒体流会话的代理）进行通信。作为这种移动的结果，服务器选择可能变得不合适。第一个CDN可以通过MN，接入网络节点，服务器或另一个节点了解MN移动性事件。第一CDN可以通过发送CDNI重选请求消息来触发上游CDN的重选，该CDNI重选请求消息包括用于上游CDN的信息以在具有指定内容的MN执行请求路由，在不同的位置。上行CDN可以执行请求路由过程。上游CDN可以将请求路由结果返回到第一个CDN。初始服务器可以向应用发送重定向消息，该消息可以解释消息并从不同的服务器继续流。

摘要： A method and apparatus for automatically discovering and retrieving content based on a content identity (ID) are disclosed. User agents and content control entities in the network interact for registering the content, discovering the content hosts and sources, and initiating and controlling the content session. A content name resolution handler (CNRH) is provided for mapping content IDs to network locations or addresses. Two or more content service provider networks may interconnect each other to discover and retrieve the content. A content request from a client device includes a content ID that uniquely identifies a content object. The content ID is resolved with a CNRH to obtain identity information of at least one content provider for serving the content request, and the content request is forwarded to the selected content provider. The content request may be routed to the selected content provider via IP multimedia subsystem (IMS) control plane entities.

摘要： Systems and methods are described for determining an optimised sampling ratio for coding video data that reduces overall distortion introduced by the coding process. It seeks to balance the information loss introduced during downsampling and the information loss introduced during coding. The sampling ratio is generally determined by reducing, or in some cases minimizing, the overall error introduced through the downsampling process and the coding process, and may be adaptive based on the content of the video data being processed and a target bit rate. Computation power can be saved by coding a downsampled video. The process derives a plurality of downsampling ratios, and selects a downsampling ratio that reduces the total amount of distortion introduced during the down - sampling and coding stages. The down - sampling ratio may be selected given the available data transmission capacity, input video signal statistics, and/or other operational parameters, and may optimally reduce the overall distortion.
摘要翻译：描述了用于确定用于编码视频数据的优化采样率的系统和方法，其减少由编码过程引入的整体失真。它寻求平衡在下采样期间引入的信息丢失和编码期间引入的信息丢失。采样率通常通过减小或在一些情况下最小化通过下采样处理和编码处理引入的总体误差来确定，并且可以基于正在处理的视频数据的内容和目标比特率来自适应。可以通过对下采样视频进行编码来节省计算功率。该过程导出多个下采样比，并且选择降低在下采样和编码阶段期间引入的失真总量的下采样比。给定可用数据传输容量，输入视频信号统计和/或其他操作参数可以选择下采样比，并且可以最佳地降低整体失真。
