A method for recording a complete stream of live data packets from a server in a media cache with reduced server-cache bandwidth includes utilizing a first amount of server-cache bandwidth to receive only a portion of the complete stream of live data packets from the server, determining when the stream of live data packets from the server finishes, thereafter utilizing a second amount of server-cache bandwidth to receive missing portions of the complete stream of live data packets, and combining the portion of the complete stream of live data packets and the missing portions of the complete stream of live data packets to form the complete stream of live data packets in the memory.

Live stream archiving method and apparatus

A method for storing streaming media data packets in a cache includes receiving a first streaming media data packet from a streaming media server, the first streaming media data packet comprising first header data and first payload data, pre-determining a first payload checksum in response to at least a portion of the first payload data, storing at least a portion of the first header data and the first payload checksum as first packet meta data in a first data object in the cache memory, and storing the first payload data in the first data object in the cache memory, wherein the first data object is directly addressable in the cache memory via an associated object handle.

Methods and apparatus for precomputing checksums for streaming media

Techniques for caching media data, including streaming media data, using content-sensitive identifiers. The content-sensitive identifiers enable a caching proxy or a caching server to unambiguously determine the version or contents of media data cached by the caching proxy for a particular data pointer or data reference (e.g., a URL) such that an appropriate version of the media data can be served to a requesting client system in an efficient and economical manner.

Caching media data using content sensitive object identifiers

A method for storing streaming media data in a cache memory includes receiving the streaming media data from a streaming media server, the streaming media data comprising a series of packets of media data, the packets of media data including header data and payload data, separating the header data from payload data, storing a portion of the header data in a session data object in the cache memory, and storing the payload data in a first plurality of data objects in the cache memory, wherein each data object of the first plurality of data objects is directly addressable in the cache memory via an associated object handle, and wherein each data object of the first plurality of data objects stores a portion of the payload data.

Methods and apparatus for storing and serving streaming media data

A method for pre-computing a streaming media payload in a server includes receiving a data file from a streaming media server, determining a plurality of data packets from the data file, dividing the plurality of data packets into a plurality of sets of data packets, forming a plurality of data objects, each data object comprising a set of data packets from the plurality of sets of data packets, and storing the plurality of data objects in a server memory, wherein each data object is individually accessible from the server memory.

Pre-computing streaming media payload method and apparatus

A method for operating a streaming media cache includes receiving a series of streaming media data packets from an upstream server, each of the series of streaming media data packets having media data encoded in one of a plurality of encoding formats, forming bundles of data packets from the series of streaming media data packets, and storing bundles of data packets into a disk memory when every data packet within each bundle have a similar encoding format.
