    Abstract: A system for resource provisioning for content delivery of multiple services is disclosed. The system may be configured to offer multiple services, wherein at least one first offered service is delivery of prerecorded content and at least one second offered service is content delivered according to a deadline. In at least one embodiment, the first offered service may be video content, and the second offered service may be broadcast television content. The system may also be configured to deliver at least a portion of the first offered service in advance of use of that portion of the first offered service such that resource demand in connection with delivery of service content of the second offered service at peak delivery may be reduced. As such, fewer resources are needed to provide uninterrupted service of the first and second offered services.

    Abstract translation: 公开了一种用于多个服务的内容传送的资源配置的系统。 该系统可以被配置为提供多个服务，其中至少一个第一提供的服务是预先记录的内容的传送，并且至少一个第二提供的服务是根据最后期限递送的内容。 在至少一个实施例中，第一提供服务可以是视频内容，并且第二提供服务可以是广播电视内容。 系统还可以被配置为在使用第一提供服务的该部分之前提供第一提供服务的至少一部分，使得在高峰传送时与第二提供服务的服务内容的传递有关的资源需求可以是 减少 因此，需要更少的资源来提供第一和第二提供服务的不间断服务。

    Abstract: A method for transferring content includes requesting the content from a serving peer and sending the content to a requesting peer. Requesting the content includes sending a request to a tracker, receiving a request token, a path identifier, and a first peer identifier from the tracker, and sending a request message to a second peer. The first peer identifier includes an identity of a first peer, and the request message includes the request token, the path identifier, and the first peer identifier. Sending the content includes receiving the request token and the path identifier from a third peer, sending a return message to a fourth peer, and transferring the content from the serving peer to the requesting peer through a transfer path. The return message includes the path identifier and a second peer identifier. The second peer identifier includes an identity of a fifth peer. The transfer path includes at least the second, fourth, and fifth peers.

    Abstract translation: 用于传送内容的方法包括从服务对等体请求内容并将内容发送到请求对等体。 请求内容包括向跟踪器发送请求，从跟踪器发送请求令牌，路径标识符和第一对等体标识符，以及向第二对等体发送请求消息。 第一对等标识符包括第一对等体的标识，并且请求消息包括请求令牌，路径标识符和第一对等体标识符。 发送内容包括从第三对等体接收请求令牌和路径标识符，向第四对等体发送返回消息，以及通过传输路径将内容从服务对等体传送到请求对等体。 返回消息包括路径标识符和第二对等体标识符。 第二对等体标识符包括第五对等体的标识。 传送路径至少包括第二，第四和第五对等体。

    Abstract: A method includes forecasting demand for media content items of a media distribution system based on historical demand information to generate forecasted demand. The method includes generating a mixed integer program model based on storage constraints of a plurality of distribution nodes of the media distribution system, bandwidth constraints of the media distribution system, and the forecasted demand. The method includes performing a Lagrangian relaxation operation using the mixed integer program model. The method includes determining values of a cost function based on a result of the Lagrangian relaxation operation. The method includes assigning each of the media content items to a corresponding distribution node of the plurality of distribution nodes based on the cost function and the forecasted demand.

    Abstract: A content monitor includes a processor that at least receives requests from a plurality of clients for content, instructs each client to retry their respective request at a first later time if the request is received before a first time, counts the requests to determine if a number of the requests exceeds a threshold if the request is received before a second time, instructs each client to retry their respective request at a second later time if the counted number of requests does not exceed a first threshold, instructs each client to join a multicast group to receive the content when the number of requests exceeds the first threshold, and counts a number of late clients joining the multicast group after a first portion of the content has been sent to the multicast group.

    Abstract translation: 内容监视器包括处理器，其至少接收来自多个客户机的内容的请求，指示每个客户端在第一时间之前在第一时间接收到请求以后，重新尝试其各自的请求，对该请求进行计数，以确定数字 如果请求在第二次之前被接收，则请求超过阈值，如果所计数的请求数不超过第一阈值，则指示每个客户端在稍后的时间重试其各自的请求，指示每个客户端加入多播组 当请求数量超过第一阈值时接收内容，并且在内容的第一部分已经被发送到多播组之后对加入多播组的较晚客户端的数量进行计数。
