A network coding system. A packet decoding engine receives a number of received packets. A packet repository is coupled to the decoding engine to temporarily store the received packets. The packet decoding engine is configured to generate a decoding matrix by forming a sub-matrix by selecting columns of a network code matrix that have indices that are the same as the indices of the encoded packets that correspond to the selected received packets. The packet decoding engine is also configured to invert the sub-matrix to form the decoding matrix and multiply the received packet matrix by the decoding matrix to generate a recovered matrix where each column corresponds to a decoded packet.

Networking coding system in a network layer

A method for network coding includes encoding a plurality of message packets to produce a plurality of encoded packets. Each message packet and each encoded packet includes a plurality of symbols having an index and each symbol of the encoded packets is generated by applying a Reed-Solomon code to the symbols of the message packets having the same index as the symbol of the encoded packets. A length of the encoded packets is the same as a length of the message packets.
