(On behalf of the GEYSERS consortium)

TNC2011 BoF "Provisioning infrastructure services on-demand (ISOD): beyond Grids and Clouds"

Prague.CZ, May 16th, 2011

Agenda

• GEYSERS: Problem Statement & Project Challenges

• RORA Model & Use Cases

• Service Delivery Framework & Architecture

• NIPS: Network + IT Provisioning Service

6/6/2011 2

Our problem statement

• New emerging applications with highly demanding network & IT resource requirements, but still unable to exploit the potentialities of optical network technologies

• Optical Network layer unaware of applications’ dynamic requirements

• Net & IT resources are being 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 infrastructures

• Generate opportunities for new business models: • Multiple virtual networks integrated with IT resources offered as a service

• Use of latest advances in network virtualization, physical resource partitioning

• Customized virtual networks supporting dynamic Optical Network + IT provisioning services

The RORA Model

6/6/2011 5

• Based on four components: – Resources, Ownership, Roles, Actors

• It allows: – the decoupling of legacy integrated roles into

independent entities, thus lowering the entry barriers.

– modeling the interactions between the various entities in environments where the underlying resources are shared and each entity holds different rights over a resource

NIPS: Network + IT Provisioning Service

• New connection paradigms – Assisted unicast: quotations about network cost and performance of

[src,dst] pairs

– Restricted anycast: selection from a set of equivalent and explicitly declared IT end-points

– Full [bi-]anycast: IT end-points selection fully delegated to the NCP

• Scheduled/advance reservations • Dynamic service modification, monitoring and recovery

– Cross-layer escalation of monitoring and recovery procedures for global service resiliency

• Computation of energy efficient e2e net+IT paths

A service that allows the dynamic on-demand provisioning of network and IT resources in a single-step, through a set of

seamlessly integrated procedures

NIPS UNI • Beyond a std UNI, towards a Cloud/Service-to-Network interface

• Generalized semantics to describe – the characteristics of IT sites/resources

• i.e. resource types, capabilities and availabilities – E.g. sites, attached services, capabilities and capacities of computing and storage

elements, etc.

– ... and the IT service characteristics

• Workflow descriptions and interaction properties

• SLAs/SLSes

• AA credentials and security context
