Deep-NFVOrch: leveraging deep reinforcement learning to achieve adaptive vNF service chaining in DCI-EONs

Due to the rise of cloud computing, how to realize adaptive and cost-effective virtual network function service chaining (vNF-SC) in a datacenter interconnection based on an elastic optical network (DCI-EON) has become an interesting but challenging problem. In this work, we tackle this problem by optimizing the design of a deep reinforcement learning (DRL)-based adaptive service framework, namely...
