<p>A method and apparatus are described including performing hop-by-hop multicasting including network coding of data packets of a portion of content, wherein network coding further includes receiving an encoded data packet of a portion of content from an upstream transmitter, determining if the received encoded data packet is innovative, storing the received encoded data packet responsive to the first determination, determining if a full rank of the encoded data packet of the portion of content has been received, determining if an acknowledgement message for the portion of the content has already been sent to the upstream transmitter responsive to the second determination, sending the acknowledgement message to the upstream transmitter responsive to the third determination and discarding the received encoded data packet responsive to the first determination.</p> |
