JVET-AQ0183 AHG18: Forward Error Correction for ULL simulation software [I. Gribushin, K. Malyshev, G. Gotovskii, B. Shevchenko, S. Ikonin, E. Alshina (Huawei)]

During discussions of AHG18 ULL-related contributions, it was noted that traditionally error resilience is handled at the network or application level, e.g., by applying Forward Error Correction (FEC). This contribution describes experiments applying packet-based Reed-Solomon codes as FEC in the AHG18 ultra-low latency simulation software. The FEC functionality is implemented as part of the Network simulation application. Encoding is performed after packetization but before network transmission, whereas decoding is performed in the jitter-buffer upon packet reception, just before the received data is passed to the decoding process. The evaluation results demonstrate moderate improvement in specific configurations based on ULL CTC. It is proposed to include FEC functionality in the AHG18 simulation software and continue the study within AHG18.

It was commented that in re-transmission a packet-by-packet strategy may be unrealistic, rather than re-transmitting chunks of packets.

Decision(SW): integrate JVET-AQ0183 in AHG18 software
