A class of two-relay diamond networks is studied where the broadcast component is
modelled by two independent bit-pipes and the multiple-access component is memoryless.
A new upper is derived on the capacity which generalizes bounding techniques of Ozarow
for the Gaussian multiple description problem (1981) and Kang and Liu for the Gaussian
diamond network (2011). For binary adder MACs, the upper bound establishes the capacity
for all ranges of bit-pipe capacities.
