    摘要： One embodiment of the present invention sets forth a technique for transmitting a digital content stream through a network between at least one content server and a content player. The method includes communicating with the at least one content server to set up a plurality of parallel network connections on the network to transmit the digital content stream. The method further includes sending a first data request and a second data request within a first time limit via at least one tested network connection in the plurality of parallel network connections to evaluate whether pipelining of the digital content stream is possible for the at least one tested network connection. The method also includes utilizing pipelining to transmit the digital content stream over the at least one tested network connection based on a first response to the first data request and a second response to the second data request.

    摘要： Data can be encoded by assigning source symbols to base blocks, assigning base blocks to source blocks and encoding each source block into encoding symbols, where at least one pair of source blocks is such they have at least one base block in common with both source blocks of the pair and at least one base block not in common with the other source block of the pair. The encoding of a source block can be independent of content of other source blocks. Decoding to recover all of a desired set of the original source symbols can be done from a set of encoding symbols from a plurality of source blocks wherein the amount of encoding symbols from the first source block is less than the amount of source data in the first source block and likewise for the second source block.

    摘要： A method of encoding data operates on an ordered set of input symbols and includes generating redundant symbols from the input symbols, and includes generating output symbols from a combined set of symbols including the input symbols and the redundant symbols, wherein the number of possible output symbols is much larger than the number of the combined set of symbols, wherein at least one output symbol is generated from more than one symbol in the combined set of symbols and from less than all of the symbols in the combined set of symbols. The redundant symbols are generated from an ordered set of input symbols in a deterministic process such that a first set of static symbols calculated using a first input symbol has a low common membership with a second set of static symbols calculated using a second input symbol distinct from the first input symbol.

    摘要： In order to carry out actions such as setting up a call from an entity in the address realm of one middlebox to an entity in the address realm of another middlebox, then a middlebox control node such as a call server is used. Previously, the middlebox control node has needed to have pre-configured information about all the middleboxes and which address realms they are associated with. The present invention provides one or more middlebox-identity-providing nodes which are separate from the middlebox control node, and which are more directly connected to the end users of the service than the middlebox control node. This provides greater flexibility in network design and removes the need for middlebox information to be pre-configured at the middlebox control node. Instead, this information is sent to the middlebox control node, as part of signalling messages, from middlebox-identity-providing nodes.
