Description: Network coding has recently emerged as an alternative
to traditional routing algorithms in communication
systems. In network coding, the network nodes combine
the packets they receive before forwarding them to the
neighbouring nodes. Intensive research efforts have demonstrated
that such a processing in the network nodes can
provide advantages in terms of throughput or robustness.
These potentials, combined with the advent of ad hoc and
wireless delivery architectures have triggered the interest
of research community about the application of the network
coding principles to media streaming applications.
This paper describes the potentials of network coding in
emerging delivery architectures such as overlay or peerto-
peer networks. It overviews the principles of practical
network coding algorithms and outlines the challenges posed
by multimedia streaming applications
