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 …

Abstract The rise of Software-Defined Networking (SDN) and Network Function Virtualization
(NFV) introduce opportunities for service providers to reduce CAPEX/OPEX and to offer and …

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

With the development of telecommunication technologies and the proliferation of network
applications in the past decades, the traditional cloud network architecture becomes unable …

Cloud computing promises to provide on-demand computing, storage, and networking
resources. However, most cloud providers simply offer virtual machines (VMs) without …

Virtual network embedding, which means mapping virtual networks requested by users to a
shared substrate network maintained by an Internet service provider, is a key function that …

Virtual network embedding (VNE) is an important problem in network virtualization for the
flexible sharing of network resources. While most existing studies focus on centralized …
