A BSTRACT: Motivated by Asynchronous Transfer Mode (ATM) in telecommunication networks, we investigate the problem
of designing a virtual topology on a physical topology, which consists of finding a set of virtual paths (VPs) satisfying some
constraints in terms of load (the number of VPs sharing a physical link) and hop count (the number of VPs used to establish a
connection). For particular network: paths, we give tight bounds on the network capacity (the maximum load of a physical link)
as a function of the virtual diameter (the maximum hop count for each connection).
K EY WORDS : ATM, Virtual Path Layout, Network Design and Dimensioning, Network Optimization
