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,w...
We consider the problem of D-hop virtual path layout in ATM (Asynchronous Transfer Mode) networks. Given a physical network and an all-to-all traffic pattern, the problem consists of designing a virtual network with a given diameter D, which can be embedded in the physical one with a minimum congestion (the congestion is the maximum load of a physical link). Here we propose a method to solve this...
