In this dissertation, we deal with the design of algorithms to tackle the α-fair resource allocation problem in real-time and distributed Software-Defined Networks (SDN). First, we define three major requirements that picture the challenges of real-time algorithms implementable in modern distributed SDN controllers. Those challenges are the ability to provide feasible resource allocations at all times, good transient solutions in terms of optimality gap that converge in an acceptable number of inter-controller communication rounds, and their ability of being massively parallelized independently of the network architecture. We use the Alternating Directions Method of Multipliers to design an algorithm that simultaneously, and unprecedentedly...
