Query: Joint Switch-Controller Association and Control Devolution for SDN
  Systems: An Integration of Online Control and Online Learning   In software-defined networking (SDN) systems, it is a common practice to
adopt a multi-controller design and control devolution techniques to improve
the performance of the control plane. However, in such systems, the
decision-making for joint switch-controller association and control devolution
often involves various uncertainties, e.g., the temporal variations of
controller accessibility, and computation and communication costs of switches.
In practice, statistics of such uncertainties are unattainable and need to be
learned in an online fashion, calling for an integrated design of learning and
control. In this paper, we formulate a stochastic network optimization problem
that aims to minimize time-average system costs and ensure queue stability. By
transforming the problem into a combinatorial multi-armed bandit problem with
long-term stability constraints, we adopt bandit learning methods and optimal
control techniques to handle the exploration-exploitation tradeoff and
long-term stability constraints, respectively. Through an integrated design of
online learning and online control, we propose an effective Learning-Aided
Switch-Controller Association and Control Devolution (LASAC) scheme. Our
theoretical analysis and simulation results show that LASAC achieves a tunable
tradeoff between queue stability and system cost reduction with a sublinear
time-averaged regret bound over a finite time horizon.
