Cooperative subspace multiplexing in content delivery networks

A method for transmitting a file between a server and a client in a content delivery network, comprising:

• generating a plurality of linearly coded packets from a plurality of original packets;
• selecting a plurality of transmitting nodes to perform cooperative subspace processing;
• and
• coordinating the plurality of transmitting nodes to increase a dimension of a subspace spanned by the linearly coded packets to provide the client with a sufficient number of linearly independent coded packets from which to retrieve the plurality of original packets.

A method for transmitting data in a content delivery network, comprising:

• encoding a plurality of original packets for generating a plurality of linearly coded packets and corresponding code vectors for transfer to a destination node;
• selecting a first network channel and at least a second network channel to simultaneously employ in the transfer;
• and
• distributing a first subset of the plurality of linearly coded packets and corresponding code vectors to the first network channel and distributing a second subset of the plurality of linearly coded packets and corresponding code vectors to the at least second network channel, wherein at least one of the first subset and the second subset has a rank that is insufficient for decoding the plurality of linearly coded packets, and wherein a sum of ranks of the first subset and the second subset is sufficient for decoding the plurality of linearly coded packets.
