A basic problem in telecommunications network design is that of designing a capacitated centralized processing network. Such a network has a central processor that must be linked via a tree topology to several remote terminals that have specified demands. Each subtree off of the root is constrained to have at most a fixed, limited demand, represented by the sum of the demands of the nodes of the subtree. Finding provably optimal solutions to this class of problems has been surprisingly difficult, particularly for certain types of instances and choices of parameters. This paper presents computational results for the problem, based on a cutting plane algorithm. It first focuses on the unit-demand case, known as the
