Network virtualization has become increasingly popular in recent years. It has the potential to allow timely handling of network infrastructure requests and, after instantiated, their lifecycle. In addition, it enables improved physical resource …
As research in the area of network virtualization continues to advance, there have been numerous efforts to solve the challenge of efficiently mapping virtual networks on top of physical structures. Despite these efforts, current state-of-the-art …
One of the research challenges approached recently in the literature is the efficient mapping of virtual networks on top of physical infrastructures. Although there have been efforts to solve it, we observe that a number of virtual network requests …
Network virtualization can potentially limit the impact of attacks by isolating traffic from different networks. However, routers and links are still vulnerable to attacks on the underlying network. Specifically, should a physical link be compromised
Network virtualization is a mechanism that allows the coexistence of multiple virtual networks on top of a single physical substrate. One of the research challenges addressed recently in the literature is the efficient mapping of virtual resources on …
Although network virtualization can improve security by isolating traffic from different networks, routers and links are still vulnerable to attacks on the underlying network. High capacity physical links, in particular, constitute good targets since …
