4 GEYSERS Layered Architecture Control and Management Planes are defined Management Interfaces Control Interfaces

5 LICL Architecture 3 Virtual infrastructure isolation Virtual Infrastructure Composition and management 2 Physical Resource synchronization and monitoring Virtual Infrastructure Planning and replanning Convergence of IT and optical network resources security 1 Semantic resource description and resource information modeling Physical resource abstraction and partitioning Physical resource adaptation Physical Resources

6 Logical Infrastructure Composition Layer (LICL) Arena for creating Virtual Infrastructures, based on network and IT resources abstraction and composition Partitioning of the physical optical network and IT resources: Sync mechanisms to keep consistency (physical & virtual) Enable resource monitoring functionalities through virtual resource Provide support to the SLA mechanism needed between stakeholders Scheduling and allocation mechanisms for resources Secured access to information and resources Dynamic creation of multiple isolated virtual infrastructures sharing the same physical resources Energy efficiency consideration: LICL includes green or energyaware attributes (to be defined) in resource models Enable new constraints for path computation or IT resource selection

7 GEYSERS Service Delivery Framework 7

8 VI re-planning Detection of re-planning conditions statistics on service requests and resource utilization in medium/long terms policies for specific customers SLAs External Manager Notifications Re-planning management policies for VIP-VIO SLAs notifications for manual re-planning LICL commands and NCP re-configuration triggers for automatic re-planning Policy PCE+ VI re-planning triggers VI re-planning manager Policy Synch triggers Re-planning request Re-planning confirmation New controller NCP VI Service Coordinator LICL New virtual network node

10 Additional information

11 GEYSERS Architecture basic concepts Infrastructure service provisioning Service consisting on the offer of a net+it resources composition tuned to the suitable support of an upper application/service. Virtual Infrastructure (and its services on top) Instantiated from an underlying physical infrastructure (e.g. net+it), consists on a new composition of virtual network and IT resources (generated from the abstraction, partition, aggregation) conforming a new topology optimized for a certain use (with higher granularity and adaptation than the underlying physical infrastructure). Dynamic service Is a Service adaptable to use, for instance, Dynamic Infrastructure provisioning service will consist on a net+it resources composition that may evolve in time as use evolves, which is provisioning extra net and/or IT resources when needed or decommissioning resources when unused. Re-planing Recalculation of the virtual infrastructure when the current one doesn't fulfill in an optimal fashion the on top service requirements.
