Virtual Networks: Isolation, Performance, and Trends

Currently, there is a strong effort of the research community in rethinking the Internet architecture to cope with its current limitations and support new requirements. Many researchers conclude that there is no one-size-fits-all solution for all of the user and network-provider needs and, thus, advocate for a pluralist network architecture, which allows the coexistence of different protocol stacks running at the same time over the same physical substrate. In this paper, the authors investigate the advantages and limitations of the virtualization technologies for creating a pluralist environment for the future internet.
