1 Enhanced Network Control Plane architectures supporting Cloud Computing applications: GMPLS+/PCE+ Nicola Ciulli Project Steering Committee On-demand Infrastructure Services Provisioning Workshop, OGF 28, Munich, Mar 15 th 2010

2 On-demand Infrastructure Services Provisioning Workshop, OGF 28, Munich, Mar 15 th 2010 1 Contents A brief problem statement NCP in the GEYSERS architectural layering NCP main challenges NCP major innovations Any-IT + Network Service concept Energy-efficiency Achieving the GMPLS+/PCE+ NCP Main work items Starting points of work Planned delivery of the major results Expected impact on SDOs

3 On-demand Infrastructure Services Provisioning Workshop, OGF 28, Munich, Mar 15 th 2010 2 NCP problem statement Grids, cloud computing and SOAs at large rely on a vital commodity: the network An ever-increasing number of distributed [super-]computing applications Highly-demanding requirements for dynamicity and flexibility in Net + IT resource control (e.g. automated scaling up/down) …but their network service(s) still treated as always-on Application layer unable to exploit the automatic control potentialities of the current optical (and not-optical) network technologies IT resources dynamics completely uncorrelated from the network ones Common trend to over-provision network services inefficient resource utilization in the network, above all in case of fault recovery

4 On-demand Infrastructure Services Provisioning Workshop, OGF 28, Munich, Mar 15 th 2010 3 NCP problem statement (contd) [DEMAND] More and more massive utilisation of these Net+IT services by end-users [OFFER] A rapid migration from telecommunication networks to global communication infrastructures Network infrastructure Computing/storage elements (IT) Software and tools to control, monitor and manage the Net+IT services Often virtually composed on top of incumbent providers … and with a revolution in actors roles and responsibilities along the value-chain Infrastructure providers, network operators, virtual network operators, Service/Content providers, Over the Top (OTTs), etc.

5 On-demand Infrastructure Services Provisioning Workshop, OGF 28, Munich, Mar 15 th 2010 44 GEYSERS reference model IT: storage, computing optical infrastructure Infrastructure Providers App/Service Providers Network Infrastructure IT Infrastructure Logical Infrastructure Composition Layer Application Application Interface Application Resources Roles IT: storage, computing (virtual) Network Operators GMPLS+/PCE+ Network Control Plane (Extended ASON/GMPLS and PCE Control Plane) GMPLS+/PCE+

6 On-demand Infrastructure Services Provisioning Workshop, OGF 28, Munich, Mar 15 th 2010 5 NIPS: Network+IT Provisioning Service Beyond a UNI, towards a App-to-Net i/f Generalized semantics to describe the functional characteristics of both IT sites and NEs (exported from LICL) i.e. resource types, capabilities and availabilities E.g. sites, attached services, capabilities and capacities of network, computing and storage elements, etc. also the non-functional service characteristics Workflow descriptions Interaction properties Service Level Agreements Pricing/charging models etc. a service that allows the provisioning of network and IT resources in a single-step, through a set of seamlessly integrated procedures

7 On-demand Infrastructure Services Provisioning Workshop, OGF 28, Munich, Mar 15 th 2010 6 Planned features [1] Provide a single reference point for the Application layer (Network+IT Provisioning Service interface – NIPS) [downward] e2e dynamic (advance) reservations with differentiated service guarantees (QoS but also resiliency) on a per-user/service basis [upward] Reporting SLA fulfilment for subsequent workflow adjustments Capability of dynamic e2e resource composition of Net + IT resources One-step Net+IT resource reservation Scheduled/advance reservation (various degrees from fully distributed to centralized) Trusted mechanisms for accessing resources Coordinated recovery strategies for an overall service resiliency

8 On-demand Infrastructure Services Provisioning Workshop, OGF 28, Munich, Mar 15 th 2010 7 Planned features [2] Supporting new connection paradigms, i.e. beyond p2p assisted unicast (i.e. network quotations about performance and prices of pairs) restricted anycast (i.e. with a set of equivalent dst in which NCP+ will pick the best one) full anycast (i.e. dst choice totally delegated to NCP) Coordinated service provisioning and maintenance through the LICL Dynamic provisioning, monitoring and recovery functions Logical infrastructure re-planning based on TE considerations, network & SLA fulfilment benchmarking Backward compatibility and interoperability with std GMPLS and PCE ASON/GMPLS (by ITU-T and IETF CCAMP WG) PCE (by IETF PCE WG) UNI and E-NNI interfaces (by OIF + possible influences from OGF NSI WG)

10 On-demand Infrastructure Services Provisioning Workshop, OGF 28, Munich, Mar 15 th 2010 9 NCP major innovations Application dynamics and granularity at the user-network interface (NIPS) Extended communication paradigms assisted unicast restricted anycast full anycast New service composition dynamics at the SOA layer BoD services planned + provisioned by the NCP but optionally hocked to the NMS decision flow Scheduled BoD services handled by the NCP in a distributed/federated way Cross-layer service monitoring and escalation of recovery procedures Energy-efficient network + IT resource routing and provisioning GEYSERS enhanced NCP AAA for net+IT provisioning services
