High-Performance Forward Error Correction: Enabling Multi-Gigabit Flows and Beyond In Presence of Packet Loss On Commodity Hardware
Original language description
In demanding real-time multimedia transmissions, even a low packet loss might significantly degrade the visual quality. As retransmission is not an option in real-time transfers especially when transmitting the data over long distances, it is necessary to employ mechanisms of Forward Error Correction (FEC). Low-Density Generator Matrix (LDGM) codes are known to be suitable for coding on large block sizes, however, high bitrates of currently used video formats (FullHD, 4K) also require high throughput of FEC coding. We propose a parallel design of LDGM encoding and decoding algorithms suitable for off-theshelf, (massively) parallel platforms, such CPUs with vector units or GPUs, and evaluate our approach in real-world scenarios of high-definition and 4K video transmissions. Our results show that offloading FEC computation to such platform is beneficial for low-latency, high-quality multimedia transmissions and may even enable transmissions beyond 10 Gbps once the commodity network interfaces reach this speed.
