Network virtualization enables the co-existence of multiple virtual networks (VNs) on the
same substrate network (SN) by sharing the available resources. Virtual network embedding …

Virtual network embedding is considered an important problem to solve in order to make
infrastructure virtual-ization economically reasonable. The most efficient algorithms …

Network virtualization recognized as an enabling technology for the forthcoming networks is
utterly popular. One of the main challenges of network virtualization is called the virtual …

In the area of network virtualisation, virtual network embedding (VNE) refers to the resource
allocation problem. In the literature, researchers have proposed multiple VNE algorithms …

Virtual network embedding (VNE) is the optimization problem of finding the minimum cost
mapping between virtual and substrate networks. Although most VNE variants are NP-hard …

A major challenge in virtual network embedding is to find an efficient mapping of each virtual
network (VN) to the nodes and links in the substrate network (SN) so that the residual SN …

Network virtualization provides a powerful way to run multiple heterogeneous virtual
networks (VNs) at the same time on a shared substrate network. A major challenge in …

Network Virtualization is one of the most promising technologies for future networking.
Network Virtualization allows multiple virtual networks to coexist on same shared physical …

Virtual network embedding (VNE) that instantiates virtualized networks on a substrate
infrastructure, is one of the key research problems for network virtualization. Most existing …

In this paper, we address the problem of embedding a Virtual Network (VN) on a substrate
network in such a way that the VN remains connected in the event of single substrate link …
