SUMMARY:"Self-Adjusting Networks: From Metrics to Algorithms"
DESCRIPTION:In this talk I will present the vision of self-adjusting
 networks: communication networks whose physical topology adapts to the
 traffic pattern it serves\, in a demand-aware manner. This vision is
 reminiscent of biased and self-adjusting datastructures\, such as Mehlhorn
 trees and splay trees. Self-adjusting networks are enabled by emerging
 reconfigurable optical technologies. I will show that the benefit of
 self-adjusting networks depends on the amount of "structure" there is in
 the demand\, and present an information-theoretical approach to measure the
 complexity of traffic traces and derive entropy-based metrics accordingly.
 I will also present optimal offline and online algorithms to design
 self-adjusting networks whose performance matches the derived metrics
 asymptotically.\n\nThe talk is primarily based on the following
