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

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 …

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 …

The issue of virtual network (VN) embedding constitutes an important aspect of network
virtualization, which is considered to be one of the most crucial techniques to overcome the …

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 …

To fend off the ossification of Internet architecture, virtual network embedding has been
propounded as one of the most important techniques to address this issue. Virtual network …

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

Virtual network embedding (VNE) algorithm is always the key problem in network
virtualization (NV) technology. At present, the research in this field still has the following …

Network Virtualization (NV) techniques allow multiple virtual network requests to beneficially
share resources on the same substrate network, such as node computational resources and …
