PROJECT TITLE :

Multidomain network hypervisor for abstraction and control of openflow- enabled multitenant multitechnology transport networks [Invited]

ABSTRACT:

A virtualization design is presented for deploying multitenant virtual networks on top of multitechnology optical networks. A multidomain network hypervisor (MNH) and a multidomain SDN orchestrator (MSO) are introduced with this purpose. TheMNHprovides an abstract view of each virtual network and offers control of it to each independent client SDN controller. The MNH is in a position to supply virtual networks across heterogeneous control domains (i.e., generalized multiprotocol label switching and OpenFlow) and transport technologies (i.e., optical packet switching and elastic optical networks). The MSO is responsible for providing the mandatory end-toend connectivity. We have a tendency to have designed, implemented, and experimentally evaluated the MNH and MSO in an international testbed across Spain, UK, Germany, and Japan.
