Mechanisms such as re-direction etc. should NOT rely on multicast
capabilities of the network. These mechanisms must be able to operate
over unicast networks, given that multicast is rarely deployed these
days. Of course, such mechanisms might take advantage of multicast
where available, but then it should be optional.
The same way, multicast should not be REQUIRED for streaming. It can
be used for better efficiency, but a streaming solution should not be
designed based on the assumption that (network-level) multicast is
available everywhere.
