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 the RPP comprises a result of a parity function applied to a set comprising n segments, each belonging to a different packet from among the n data packets. Each segment of the DPP comprises a result of a parity function applied to a set comprising n segments, each belonging to a different packet selected from a group comprising the n data packets and the RPP. The processor may utilize the received packets to recover two lost packets.
