RPT: Re-Architecting Loss Protection for Content-Aware Networks
The authors revisit the design of redundancy-based loss protection schemes in light of recent advances in content-aware networking. Content-aware networks minimizes the overhead of redundancy, if the redundancy is introduced in a way that the network can understand. With this insight, they propose a new loss protection scheme called Redundant Packet Transmission (RPT). Using redundant video streaming as an example, they show that their approach, unlike FEC in traditional networks, provides low latency with high robustness and is insensitive to parameter selection. They tackle practical issues such as minimizing the impact on other traffic and the network.
