Abstract:
Emerging communication technologies allow to reconfigure the physical network topology at runtime, enabling demand-aware networks (DANs): networks whose topology is optimized toward the workload they serve. However, today, only little is known about the fundamental algorithmic problems underlying the design of such demand-aware networks. This paper presents the first bounded-degree, demand-aware network, \textit {cl-DAN} , which minimizes both congestion and route lengths. The degree bound \Delta is given as part of the input. The designed network is provably (asymptotically) optimal in each dimension individually: we show that there do not exist any bounded-degree networks providing shorter routes (independently of the load), nor do there exist networks providing lower loads (independently of the route lengths). The main building block of the designed \textit {cl-DAN} networks are \textit {ego-trees} : communication sources arrange their communication partners in an optimal tree, individually. While the union of these ego-trees forms the basic structure of \textit {cl-DANs} , further techniques are presented to ensure bounded degrees (for scalability).
