Abstract :
It is shown that one cannot always layer, or separate, channel and network coding for multicasting in deterministic relay networks with no interference. We call such networks Aref networks. The suboptimality of such layering in Aref networks is in contrast to the optimality of a similar layering in networks of discrete memoryless channels and certain networks of two-way channels
