Incentive-driven service provisioning in multi-broker orchestrated multi-domain SD-EONs

This paper studies the incentive-driven service provisioning framework for multi-broker orchestrated multi-domain software-defined elastic optical networks (SD-EONs). We first model the incentive-driven service provisioning paradigm as a noncooperative game, where the brokers compete with each other for inter-domain provisioning tasks. A kernel density estimation (KDE) based intelligent bidding strategy is presented for the brokers to decide the optimal service prices. To overcome the drawbacks of noncooperative game modeling, we further discuss the cooperative marketing strategy for the brokers and present a collision-aware Nash bargaining method to facilitate Pareto-efficient provisioning tasks partitioning among the brokers. Simulation results indicate that the KDE-based bidding strategy effectively improves the broker profit in the noncooperative scenario, while the cooperative game-theoretic approach can resolve the issues in the noncooperative game modeling to enable much higher broker profit without sacrificing the interests of domain managers.
