Abstract
Methods and systems that enable recovery of a lost packet from an incomplete block transmitted over a communication network. In one embodiment, a system includes a first processor configured to: receive a block of packets during a period spanning a certain duration, calculate a parity packet (PP) for the block, and provide in PP an indication of the number of packets in the block, where the block comprises k<n packets, and the certain duration is long enough to enable the processor to receive at least n packets. A transmitter transmits the k packets and PP. A receiver receives, over a period that is not longer than the certain duration, packets sent by the transmitter. A second processor detects, based on the number indicated in PP, that one of the k packets of the block was lost, and utilizes PP to recover said lost packet.
