On Leveraging Future Internet Services through Multidomain Layer 1 Virtualization

NGNs are being envisioned to circumvent the ossification of current Internet and leverage advanced and profitable services. It is still unclear how this will be realized, but network infrastructure virtualization continues to gain momentum as an elegant solution to accommodate concurrent NGNs in a flexible, robust fashion. Despite this trend and the fact that the Internet will continue to grow as autonomous domains, the virtualization of a multidomain infrastructure is yet unexplored. This paper tackles this very relevant research problem, presenting a preliminary architecture to enable NGNs services through a multidomain layer 1 virtualization approach.
