Abstract:
Methods and systems that enable recovery lost packets that were transmitted over a communication network. In one embodiment, a device includes a receiver and a processor. The receiver receives n packets that belong to a set comprising n+2 packets transmitted over the communication network, where the set includes: n data packets, a row parity packet (RPP), and a diagonal parity packet (DPP). Each received packet comprises n segments. Each segment of RPP comprises a result of a parity function applied to a row parity set comprising n segments, each belonging to a different packet from among the n data packets. Each segment of DPP comprises a result of a parity function applied to a diagonal parity set comprising n segments, each belonging to a different packet selected from a group comprising the n data packets and RPP. The processor utilized the received packets to recover two lost packets.

Claim (Index 2):
The device of  claim 1 , wherein for each packet, from among the n data packets, DPP includes a segment calculated based on a diagonal parity set that does not include any of the segments of the packet; wherein the processor utilizes an iterative process to recover the values of the segments of two data packets, from among the n data packets, which were not received; and wherein the iterative process involves performing the following until all segments of the two packets are recovered: (i) selecting a parity set, which has only a single segment that has yet to be recovered, from among the row parity sets used to calculate the segments of RPP or from among the diagonal parity sets used to calculate the segments of DPP, (ii) recovering the values of the single segment based on values of the rest of the segments belonging to the selected parity set.
