  1. The GEYSERS project S. Figuerola, D. Simeonidou, N. Ciulli, R. Nejabati, T. M. Bohnert, J.A. Garcia-Espin, P. Vicat-Blanc, B. Belter, M. Biancani and J. Jimenez on behalf of the GEYSERS consortium Future Network Mobile Summit Florence, 16th – 18th June 2010

  2. GEYSERS @ a glance • GEYSERS: • Generalized Architecture for Dynamic Infrastructure Services • Instrument:Collab. Project - Large Scale Integrated Project (IP) • Activity: ICT-2009.1.1 The Network of the Future, FP7 Call 4 • Project duration: 36 months • Project start date: January 2010 • Project budget: 10.433.205€ (7.035.000€ EC contribution) • Project resources: 947 person months Future Network & Mobile Summit 2010 Florence, Italy

  3. What is GEYSERS about? • A novel architecture and tools for the composition of logical infrastructures, that share the same physical subbstrate. • An enhanced NCP (ASON/GMPLS + PCE) architecture and protocols to use these logical infrastructures to provide advanced transport services coupled with IT services. • Business cases that impact infrastructure providers, network & IT operators and application providers. • Provide an enabler for the integration of dynamic optical network services in cloud computing scenarios. • Architecture definition, design, prototyping and validation Future Network & Mobile Summit 2010 Florence, Italy

  4. Our problem statement • New emerging applications with highly demanding network & IT resource requirements, but still unable to exploit the potentialities of the current optical network technologies • Network layer unaware of applications’ dynamic requirements • Net & IT resources controlled separately without any integration • Optical infrastructure providers and network operators unable to provide enhanced and customized network services • Today just simple connection services over generic optical network infrastructures • Opportunities for new business models: • Multiple virtual networks integrated with IT resource offered as a service • Customized virtual networks supporting dynamic Optical Network + IT provisioning services Future Network & Mobile Summit 2010 Florence, Italy

  5. GEYSERS and CloudComputing Why Cloud Computing is relevant for GEYSERS: • The way in which Cloud computing services (application or infrastructure) are accessed and used increases the criticality of network QoS. • Network infrastructure services could be offered and managed using similarownership models and enabling similar virtualization and elasticity capabilities. • The convergence of IT and Telco service management is an important outcome for Cloud computing to reach a new level of critical mass. • As cloud computing increasesin popularity and scale, massive utilisation of network infrastructurewill be observed.

  7. GEYSERS Actors and Roles GEYSERS roles Current actors Virtual Infrastructure Operator (VIO) IT infrastructure operator IT Service Providers NET infrastructure operator Virtual Infrastructure Provider (VIP) Legacy Telcos & Carriers Infrastructure Provider & Management Physical Infrastructure Provider (PIP) Future Network & Mobile Summit 2010 Florence, Italy

  8. Rationale • Four pillars for contextualising GEYSERS use cases (RORA): • Resources (net + IT) • Ownership (models) • Roles • Actors ACTOR ROLE OWNERSHIP PATTERN … RESOURCE ONGOING WORK Future Network & Mobile Summit 2010 Florence, Italy

  9. RORA Model Basics • Role and Actor: • Role: Names a behaviour of an entity participating in a particular context. • Actor:An entity taking part in a use case that may or may not interact with other entities that take one or several roles. • Provider vs. Operator: • Provider: A role for offering a resource or a service. • Operator: A role for controlling a resource, commodity or service. • Requester: A role for requiring the usage of a resource. • Ownership (simplified) • Economical: rights for physically controlling the access to the resource. • Administrative: rights to configure or operate a resource. • Usage: utilisation rights of the resources for executing a workflow. ONGOING WORK Future Network & Mobile Summit 2010 Florence, Italy

  10. Roles and Capabilities • Physical Infrastructure Provider (PIP) • Owns economical rights over PHY resources • Virtual Infrastructure Provider (VIP) • Owns administrative rights for planning virtual infrastructures • Virtual Infrastructure Operator (VIO) • Owns administrative rights over virtual infrastructures • User/application/Service provider • Consumes Net+IT unified services (NIPS UNI) as resources ONGOING WORK Future Network & Mobile Summit 2010 Florence, Italy

  11. Workflow design process ONGOING WORK Future Network & Mobile Summit 2010 Florence, Italy

  12. Service Management Layer (SML) • GEYSERS will provide an entity to coordinate the deployment of network services and IT resources • Awareness of constraints/SLAs • Delegation of network-related connection services to the NCP • Alignment of IT resource and networkservice allocation • Goal: Convergence of network and IT service management • Interaction with NCP for seamless “one-step” provisioning of network + IT edge resources (NIPS) • Analyze the work done at standarization bodies and other projects ONGOING WORK Future Network & Mobile Summit 2010 Florence, Italy

  13. Logical Infrastructure Composition Layer (LICL) • Partitioning of the physical optical network and IT resources through resource virtualization: • Synchronization mechanisms to keep consistency (physical & virtual) • Resource monitoring functionalities and SLA support • Scheduling & allocation mechanisms for both, static & dynamic resources • Authorised and Authenticated access to information • Composition of network and IT resources from multiple providers • Dynamic creation of multiple isolated virtual infrastructures sharing the same physical resources • Management of static and dynamic resource sharing between infrastructure providers and network operators ONGOING WORK Future Network & Mobile Summit 2010 Florence, Italy

  14. Enhanced Network Control Plane I • Enhancedtransport network connection paradigms (assisted unicast, restricted anycast, full anycast, scheduled connections) • Virtual infrastructure dynamicre-planning (Enhanced TE in GMPLS/PCE) • Enhanced TE in GMPLS/PCE to trigger re-planning functionalities • Dynamic provisioning, monitoring and recovery functions • Coordinated recovery escalation among LICL/NCP/[appl. layer] • Backward interoperability with std GMPLS/PCE • Cross-layer service monitoring and coordinated recovery escalation • Energy-aware and IT-aware path computation algorithms • Interaction with AA[A] frameworks for service provisioning ONGOING WORK Future Network & Mobile Summit 2010 Florence, Italy

  15. Enhanced Network Control Plane II • GMPLS controllers - Routing Plane: • Advertisement of parameters associated to Network and IT resources • IT resources information collected from the App. Layer (NIPS-UNI) • Network resources information collected from LICL • Required extensions to the Routing Plane for: • IT resources characterization • parameters describing energy consumption • scheduled(network + IT) resources • GMPLS controllers - Signalling Plane: • Signalling extensions for: • Network + IT service provisioning requests • Immediate and scheduled reservations • Assisted unicast, Anycastconnections • Escalation of recovery procedures • Combined authorization mechanisms ONGOING WORK Future Network & Mobile Summit 2010 Florence, Italy

  16. GEYSERS & Green IT • Infrastructure optimization (right-size = as much as I need) • Efficient usage and resources optimization • Resource optimization and sharing • Power down un-used infrastructure • Power consumption awareness • Energy efficient logical composition Future Network & Mobile Summit 2010 Florence, Italy

  17. Expected business impact • GEYSERS concepts will allow the development of new actors in the ICT environment • GEYSERS approach will enable telcos to access new marketsand strongly impact new business models • moving their business towards higher value application layers (IaaS) • E.g. allowing to compose network + IT edge resources • GEYSERS approach will overcome domain segmentation • GEYSERS tools will provide dedicated support of highly-IT reliant distributed mission critical enterprise applications • Optimize the infrastructure usage (CAPEX and OPEX) Future Network & Mobile Summit 2010 Florence, Italy

  18. GEYSERS Testbed Future Network & Mobile Summit 2010 Florence, Italy

  19. An example scenario: the VIO Network Service Gold Customer Cloud Service Provider (i.e. EU ‘Amazon’) • No CAPEX for the VIO to enter the business • Virtual network and IT infrastructure hired from Infrastructure Providers • NCP controllers licensed by stack providers • Specialized network(s) and related services; some advanced (cloud) • Advantages for both parties: • Telcos and IT Data Centers can rent out parts of their infrastructure to maximize utilization • Reduced CAPEX and time-to-market for the VIO • Pay-as-you-grow model and SLAs: depending on the business the VIO can rent more or release resources • Flexibility to easily cover new customer application demands with dedicated virtual infrastructures Virtual Infrastructure Operator (VIO) Enhanced NCP stack providers Virtual Network Providers Virtual Storage and Computer resources at the edges Infrastructure Provider (IP) Infrastructure Provider (IP) Future Network & Mobile Summit 2010 Florence, Italy

  20. Preliminar Conclusions • GEYSERS will: • Facilitate the end-to-end service delivery • Provide a new business approach where actors can take new roles • Rely on partitioning infrastructures (optical + IT) to create specific virtual infrastructures • Each virtual infrastructure will be controlled by an enhanced NCP • The GEYER vision will be realised by implementation the following technical objectives: • Definition and design of a new Logical Infrastructure Composition Layer (LICL) • Definition and design of an enhanced Network Control Plane (NCP) architecture and protocol extensions • Provide a cost-effective, proof-of-concept implementation of the LICL and NCP • Deploy a distributed and multi-site validation test-bed.
