The emerging software defined networking (SDN) paradigm separates the data plane from
the control plane and centralizes network control in an SDN controller. Applications interact …

Bandwidth fragmentation, a serious issue in elastic optical networks (EONs), can be
suppressed by proper management in order to enhance the accommodated traffic demands …

The computing power network (CPN) has emerged as a promising networking paradigm in
recent times. Since the characteristics of high bandwidth, low delay and high reliable …

As an integrated environment deployed with wired and wireless infrastructures, the smart
city heavily relies on the wireless-optical broadband access network. The information flows …

5G network slicing allows partitioning of network resources to meet stringent end-to-end
service requirements across multiple network segments, from access to transport. These …

Based on the concept of infrastructure as a service, optical network virtualization can
improve the efficiency of network infrastructure by sharing the physical substrate network …

Research into all optical network (AON) technology has been ongoing over the past decade,
and new features are constantly being developed. The advantages of AON include large …

This paper addresses the problems of mapping virtual optical networks (VONs) onto space-
division-multiplexing elastic optical data center networks (SDM-EODCNs). We first propose …

Efficient utilization of spectrum is a key concern in the soon to be deployed elastic optical
networks (EONs). To perform routing in EONs, various fixed routing (FR), and fixed-alternate …

An important challenge in network virtualization is the process of assigning physical
resources to virtual network requests, where virtual node resources represent the demands …
