摘要： A chunk request scheduler is provided for HTTP adaptive streaming. Requests for media chunks are scheduled over a network by requesting the media chunks over at least one connection; storing the media chunks in at least one buffer; monitoring a level of the at least one buffer; and selectively switching between at least two predefined download strategies for the request based on the buffer level. Requests for media chunks can also be scheduled over a network by obtaining an ordering of the connections based on a rate of each connection; storing the media chunks in at least one buffer; and requesting the media chunks over the ordered plurality of connections based on a size of the media chunks. For example, audio chunk requests can be scheduled over TCP connections having a lower rate order and video chunk requests can be scheduled over TCP connections having a higher rate order.
摘要翻译：为HTTP自适应流提供了块请求调度程序。通过请求媒体块至少一个连接，通过网络调度媒体块的请求; 将所述媒体块存储在至少一个缓冲器中; 监视所述至少一个缓冲器的级别; 以及基于所述缓冲器级别选择性地在所述请求的至少两个预定义的下载策略之间切换。也可以通过网络调度对媒体块的请求，通过基于每个连接的速率获得连接的顺序; 将所述媒体块存储在至少一个缓冲器中; 以及基于所述媒体块的大小向所述有序的多个连接请求所述媒体块。例如，可以通过具有较低速率顺序的TCP连接来调度音频块请求，并且可以通过具有较高速率顺序的TCP连接调度视频块请求。

摘要： A method comprises associating at least one cache replacement granularity value with a given one of a plurality of content streams comprising a number of segments, receiving a request for a given segment of the given content stream in a network element, identifying a given portion of the given content stream which contains the given segment, updating a value corresponding to the given portion of the given content stream, and determining whether to store the given portion of the given content stream in a memory of the network element based at least in part on the updated value corresponding to the given portion. The at least one cache replacement granularity value represents a given number of segments, the given content stream being separable into one or more portions based at least in part on the at least one cache replacement granularity value.

摘要： A method comprises receiving a first request for a first segment of a content stream in a network element from a given one of a plurality of clients, determining in the network element whether the first segment is stored in a memory of the network element, sending a second request for the first segment from the network element to a server responsive to the determining step, receiving a response comprising the first segment in the network element from the server responsive to the second request, and sending the first segment from the network element to the given one of the plurality of clients. The first segment is related to a second segment of the content stream, the relationship being transparent to the network element but being inferable based at least in part on at least one of the first request, the response and one or more prior requests.

摘要： A content distribution network (CDN) comprising a hierarchy of content storage nodes (CSNs) or caches having storage space that is allocated between local space for storing locally popular content objects and federated space for storing a portion of the less popular content objects. Local space and federated space based upon changes in content object popularity and/or other utility factors. Optionally, parent/child (upstream/downstream) communication paths are used to migrate content between CSNs or caches of the same or different hierarchical levels to avoid utilizing higher price top hierarchical level communications channels.

摘要： When an intelligent VoIP endpoint terminal on a VoIP network becomes inoperative for any reason and can't respond to a service request that it had been programmed for, rather than leaving that service request unfulfilled, a VoIP network-hosted instance of that primarily endpoint terminal-provided service is invoked to handle that request and provide the service that would have otherwise been provided by the endpoint terminal. The network-hosted instance thus executes the requested service on behalf of the unavailable endpoint terminal.
摘要翻译：当VoIP网络上的智能VoIP端点终端由于任何原因而变得不能工作，并且无法响应已编程的服务请求，而不是使该服务请求未实现时，该主要端点终端的VoIP网络托管实例调用提供的服务来处理该请求并提供将由端点终端提供的服务。因此，网络托管的实例代表不可用的端点终端执行所请求的服务。
