Network virtualization is recognized as an enabling technology for the future Internet. It aims
to overcome the resistance of the current Internet to architectural change. Application of this …

Recently, several large-scale software defined networking (SDN) testbeds have been
designed and developed. These SDN testbeds have spurred numerous network …

Virtual network embedding arranges virtual network services onto substrate network
components. The performance of embedding algorithms determines the effectiveness and …

In this paper, after proposing a novel metric, ie, global resource capacity (GRC), to quantify
the embedding potential of each substrate node, we propose an efficient heuristic virtual …

Network virtualization (NV) is a technology with broad application prospects. Virtual network
embedding (VNE) is the core orientation of VN, which aims to provide more flexible …

Network virtualization enables the share of a physical network among multiple virtual
networks. Virtual network embedding determines the effectiveness of utilization of network …

Network virtualization (NV) is a promising approach to remove the ossification of current
Internet. Virtual network embedding (VNE) is the key issue in NV which efficiently and …

Fog computing, combined with traditional cloud computing, offers an inherently distributed
infrastructure–referred to as the cloud-to-edge continuum–that can be used for the execution …

Network virtualization can offer more flexibility and better maintainability for the current
Internet through allowing multiple heterogeneous virtual networks (VNs) to share the …

Network virtualization helps overcome shortcomings of the current Internet architecture. The
virtualized network architecture enables coexistence of multiple virtual networks (VNs) on an …
