Abstract--We consider multicast network codes that allow to
tradeoff throughput against cost. We construct a single code that
enables the source to control the throughput, always achieving
the minimum possible cost per transmitted symbol. Nodes in the
network perform linear coding operations that are the same for
all achievable throughput­cost pairs. On each of their outgoing
edges nodes transmit either symbols that are obtained by these
fixed linear combinations or nothing at all.
