摘要:
Systems, methods and computer program products for facilitating the recovery of lost real-time media packets within a computer network real-time application implementing Forward Error Control (FEC), such that server performance is not affected from a CPU and memory perspective, are disclosed. In an embodiment, a conference server that is part of a communication network compliant with the Real Time Transport Protocol (RTP) is able to avoid regenerating FEC packets by not performing any FEC coding operation on the packets unless it is flagged to indicate regeneration via an FEC (e.g., Reed-Solomon) coding is necessary. Absent the flag, the conference server updates the received FEC packet as per the RTP and transmits the packet to its ultimate destination. Such disclosed systems, methods and computer program products are independent of the nature of the media being protected and flexible enough to support a wide variety of FEC techniques.
