This paper deals with the multiple link/node substrate failures that impact a multicast virtual
network (MVN) in which link recovery is not feasible and node migration is mandatory. A …

Network Virtualization provides operators with the ability to move components of a virtual
network (VN), or even the entire VN, between physical hosts, in real-time and seamlessly to …

Network Function Virtualization (NFV) provides an effective way to reduce the network
provider's cost by allowing multiple Virtual Networks (VNs) to share the underlying physical …

Virtual network embedding (VNE) is defined as the allocation of network resources to
multiple virtual networks (VNs) and is recognized to be a challenging task to perform …

Providing reliability guarantees for services hosted in cloud data center networks is a well
studied problem that received much attention from the literature in recent years. Yet, the …

Multicast virtual network (MVN) cloud services have tight restrictions in terms of coverage,
delay, delay variation, and reliability. However large disasters impose key challenges, and …

This paper addresses the problem of recovering virtual networks (VNs) affected by a
substrate node failure. A novel heuristics-based algorithm that efficiently reallocates new …

Network virtualization has garnered great attention as a promising way to reform the current
Internet. Multiple virtual networks (VNs) can be embedded onto the same substrate network …

Network virtualization allows multiple virtual networks to coexist on a shared physical
substrate infrastructure. As network virtualization becomes popular, the problem of efficiently …

With network virtualization more and more popular, how to protect the virtual networks (VNs)
from a single substrate link failure is increasingly important. Existing protection schemes like …
