This letter considers a problem of realizing an undirected vertex-capacitated network from the view of two types; flow-saturated and flow-unsaturated. As a result, two necessary and sufficient conditions for a given matrix to be realizable as a flow-saturated network and as both a flow-saturated network and a flow-unsaturated one have been shown.
