Encoding data with parity information and transmitting it over at least three paths to enable data reconstruction in the event of a path failure

摘要

A system comprises at least two nodes with at least three paths between a first node and a second node of the at least two nodes, and a controller. An input data stream is received at the first node where the controller applies a coding scheme to the input data stream. The input data is encoded with parity information and the encoded data is transmitted over the at least three paths to the second node, such that, in the event of failure of any path (fig. 1b), the data can be reconstructed from the data and parity information sent on the other paths. The parity information may be derived using an XOR function, hamming or Reed-Solomon codes.
