For a sparsely connected and balanced network with unknown interaction delays and 1D elements, we show that driving the network to steady states can reveal its cooperative architecture, i.e., the dynamics and output functions of individual nodes and the connection topology. Our approach is robust and can be extended to (sub)networks with a small topology uncertainty. Some examples are presented to illustrate the proposed identification method.
