“…However, it did not distinguish service categories but transferred all the services through multiple paths, which would increase the extra cost and fail to balance the relationship between link load and link transmission overhead. Han et al proposed a VNE framework based on QoS satisfaction and network reconstruction. It improved operating income fitting each VN with a specific VN whose QoS meets the requirements and combining with VN re‐embedding.…”

Summary The fiber‐wireless (FiWi) access network is a very promising solution for next‐generation access networks. Because of the different protocols between its subnets, it is hard to globally optimize the operation of FiWi networks. Network virtualization technology is applied to FiWi networks to realize the coexistence of heterogeneous networks and centralized control of network resource. The existing virtual resource management methods always be designed to optimize virtual network (VN) request acceptance rate and survivability, but seldom consider energy consumption and varied requirements of quality of service (QoS) satisfaction, which is a hot and important topic in the industrial field. Therefore, this paper focuses on the QoS‐aware cross‐domain collaborative energy saving mechanism for FiWi virtual networks. First, the virtual network embedding (VNE) model, energy consumption model, and VNE profit model of FiWi networks are established. Then, a QoS‐aware in‐region VN embedding mechanism is proposed to guarantee service quality of different services. After that, an underlying resource updating mechanism based on energy efficiency awareness is designed to realize low‐load ONU and wireless routers co‐sleep in FiWi networks. Finally, a QoS‐aware re‐embedding mechanism is presented to allocate proper resource to the VNs affected by the sleeping mechanism. Especially for video VNs, a re‐embedding scheme which adopts traffic splitting and multipath route is introduced to meet resource limitation and low latency. Simulation results show that the proposed mechanism can reduce FiWi network's energy consumption, improve VNE profit, and ensure high embedding accepting rate and strict delay demand of high‐priority VNs.

“…Nevertheless, the relatively slow development makes access network become the bottleneck of "last mile" communication networks [2,3] . To address this problem, a novel Fi-Wi converged broadband access network structure is proposed by academic community in recent years [4,5] . It inherits the high bandwidth capacity and high stability from optical access networks, as well as the high flexibility and affordability from wireless networks.…”
