    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 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 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: A normalized cost measure is determined for each encoded video segment within each of a plurality of sequences of encoded video segments that are associated with a video program and stored in a cache memory, relative to the sequence to which the encoded video segment belongs. One or more encoded video segments are selected from among the encoded video segments in the plurality of sequences, based on the normalized cost measures. The selected encoded video segments are removed from the cache memory. An encoded video segment having a lowest normalized cost measure among the encoded video segments in the plurality of sequences may be selected, for example.

    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.
