DF Raptor forward error correction (FEC) technology overcomes TCP’s bandwidth inefficiencies by providing an alternative way to reliably transfer data over an IP network that maximizes throughput and fully uses available bandwidth regardless of network congestion, packet loss, or latency.

Operators continue to search for more and better ways to provide desirable services to consumers, who crave high-quality, bandwidth-intensive content when they want it.

This monograph describes the theory behind Raptor codes, and elucidates elements of the processes behind the design of two of the most prominent members of this class of codes: R10 and RaptorQ (RQ).
