In a network for reliable transfer of packets from a transmitter to a receiver using an Internet Protocol (IP), a system for packet recovery comprising a detection block (detector) for packet loss detection and a probe device (probe) for Forward Error Correction (FEC) packets transmission, wherein the detector includes means for sending a missing packet report to the probe upon detecting a missing packet, wherein the probe includes means for storing received packets, sending FEC packets and adapting a size of the FEC packets to an error rate computed from the missing packet reports, wherein the size of FEC packets is made larger or smaller responsive to the error rate increasing or decreasing, respectively, and wherein the probe is located close to the transmitter for reliable packets reception and the detector is located close to the receiver for reliably detecting loss of packets in a receiver's surroundings. |
