Detlef, you now talk about link-layer FEC while at the beginning of
this thread and following the subject, we talk about congestion control
(i.e. at transport layer).
The erasure codes presented are based at the transport or application
layers, for instance, to prevent retransmission due to big delay or to
attempt to implement anarchical network proposals.
