Embedding a sequence of virtual networks (VNs) into a given physical network substrate to
accommodate as many VN requests as possible is known to be NP-hard. This paper …

Virtualizing and sharing networked resources have become a growing trend that reshapes
the computing and networking architectures. Embedding multiple virtual networks (VNs) on …

Network virtualization allows multiple heterogeneous virtual networks (VNs) to coexist on a
shared infrastructure. Efficient mapping of virtual nodes and virtual links of a VN request onto …

Embedding of virtual network (VN) requests on top of a shared physical network poses an
intriguing combination of theoretical and practical challenges. Two major problems with the …

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

Virtual network embedding (VNE), working as a key step for network virtualization, has
recently gained intensive attentions from the research community. In this paper, we propose …

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 is a promising new resource management approach that allows
customized virtual networks (VNs) to be multiplexed on a shared physical infrastructure. In …

Network Virtualization provides a promising tool to allow multiple heterogeneous virtual
networks to run on a shared substrate network simultaneously. A long-standing challenge in …
