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 …

Based on the concept of infrastructure as a service, optical network virtualization can
facilitate the sharing of physical infrastructure among different users and applications. In this …

This paper tries to solve the location-constrained virtual network embedding (LC-VNE)
problem efficiently. We first investigate the complexity of LC-VNE, and by leveraging the …

With the boom of Internet of Things (IoT), an increasing amount of data from IoT applications
is moved to geo-distributed data centers (DCs) for data analysis. Massive compute …

With its agile spectrum management in the optical layer, the flexible-grid elastic optical
network can become a promising physical infrastructure to efficiently support the highly …

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 …

In Network Function Virtualization (NFV), traditional purpose-built proprietary middle-boxes
are replaced with virtual network function (VNF) instances that are deployed over generic …

Network operators must continuously scale the capacity of their optical backbone networks
to keep apace with the proliferation of bandwidth-intensive applications. Today's optical …

With network virtualization, the physical infrastructure can be partitioned into multiple
parallel virtual networks for sharing purposes. However, different transport technologies or …

The proliferation of Internet of Things (IoT) applications has led to the interconnection of
multiaccess edge computing (MEC) systems through metro optical networks. To cater to …
