A method for modifying redundancy information associated with encoded data passing from a first node to a second node over data paths includes receiving first encoded data including first redundancy information at an intermediate node from the first node via a first channel connecting the first node and the intermediate node, the first channel having first channel characteristics and transmitting second encoded data including second redundancy information from the intermediate node to the second node via a second channel connecting the intermediate node and the second node, the second channel having second channel characteristics. A degree of redundancy associated with the second redundancy information is determined by modifying the first redundancy information based on one or both of the first channel characteristics and the second channel characteristics without decoding the first encoded data.
