GEYSERS vision is to qualify optical infrastructure providers and network operators with a new architecture, to enhance their traditional business operations. Optical network infrastructure providers will compose logical infrastructures and rent them out to network operators; network operators will run cost-efficient, dynamic and mission-specific networks by means of integrated control and management techniques. In the GEYSERS concept, high-end IT resources at users' premises are fully integrated with the network services procedures, both at the infrastructure planning and connection provisioning phases.Following this vision, GEYSERS will specify and implement a novel optical network architecture able to support "Optical Network + Any-IT" resource provisioning seamlessly and efficiently. Energy consumption metrics for the end-to-end service routing are part of this efficiency.GEYSERS is proposing to:- Specify and develop mechanisms that allow infrastructure providers to partition their resources (optical network and/or IT), compose specific logical infrastructures and offer them as a service to network operators. This will be done overcoming the current limitations of networks/domain segmentation, and will support dynamic and on-demand changes in the logical infrastructures.- Specify and develop a Network Control Plane for the optical infrastructure, by extending standard solutions (ASON/GMPLS and PCE), able to couple optical network connectivity and IT services automatically and efficiently, and provide them in 1 step, dynamically and on-demand, including infrastructure replanning mechanisms.These achievements will enable infrastructure providers, network operators and application providers to participate in new business scenarios where complex services with complex attributes and strict bandwidth requirements can be offered economically and efficiently to users and applications. The GEYSERS outcomes will be validated in an EU-wide optical network test-bed.
