Coordinated and Unified Control Scheme of IP and Optical Networks for Smart Power Grid

Abstract

As new services of the smart power grid emerge with diversity and complexity, great challenge and demand is presented for traditional IP data network and optical network to realize coordinated control. Benefiting from advantages of concentration, open, manageability and controllability, this paper proposes a power-grid oriented concentrated unification control architecture of IP and optical networks, together with coordinated services control mechanism, with the aim to achieve highly efficient coordination between IP network and optical network. Under this concentrated unification control architecture, an OpenFlow protocol based unified control scheme is also proposed and designed, by making full use of existing connections on optical layer to reach fast establishment for services produced by smart power grid. Therefore, the support ability of IP and optical networks to power-grid services can be greatly improved.
