Integrated OpenFlow-GMPLS control plane: an overlay model for software defined packet over optical networks.

Bandwidth demands resulting from generated traffics by emerging applications, when aggregated at the edge of the networks for transport over core networks can only be met with high-capacity WDM circuit switched optical networks. An efficient end-to-end delivery of packet streams in terms of network control, operation and management is one of the key challenges for the network operators. Therefore, a unified control and management plane for both packet and optical circuit switch domains is a good candidate to address this need.

An impairment-aware virtual optical network composition mechanism for future Internet.

In this paper, a novel Infrastructure as a Service architecture for future Internet enabled by optical network virtualization is proposed. Central to this architecture is a novel virtual optical network (VON) composition mechanism capable of taking physical layer impairments (PLIs) into account. The impact of PLIs on VON composition is investigated based on both analytical model of PLIs and industrial parameters.
