Perhaps this is of interest to this group too…

> Forward Erasure Correction (FEC) is a reliability mechanism that is
> distinct and separate from the retransmission logic in reliable
> transfer protocols such as TCP. FEC coding can help deal with losses
> at the end of transfers or with networks having non-congestion
> losses. However, FEC coding mechanisms should not hide congestion
> signals. This memo offers a discussion of how FEC coding and
> congestion control can coexist. Another objective is to encourage the
> research community to also consider congestion control aspects when
> proposing and comparing FEC coding solutions in communication
> systems.
> 
> This document is the product of the Coding for Efficient Network
> Communications Research Group (NWCRG). The scope of the document is
> end-to-end communications; FEC coding for tunnels is out of the scope
> of the document.
