Background, Present & Future Virtual Infrastructures Network Virtualisation APAN, 30 th meeting, Hanoi, Vietnam 3 August 2010
What is GEYSERS about? • A novel architecture and tools for the composition of virtual infrastructures , that share the same physical substrate. • 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 APAN, 30 th meeting, Hanoi, Vietnam 4 August 2010
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 • Generate opportunities for new business models: • Multiple virtual networks integrated with IT resource offered as a service • Use of latest advances in network virtualization, physical resource partitioning • Customized virtual networks supporting dynamic Optical Network + IT provisioning services APAN, 30 th meeting, Hanoi, Vietnam 5 August 2010
Why Infrastructure Virtualisation? • It helps on de-ossifying the current network architectures. • It allows multiple virtual infrastructures to coexist over a shared physical infrastructure. • It provides paths to the Future Internet approaches. • Allows the deployment of new business roles and players. • Reduced/shared cost of ownership. • It optimizes the resource (network and IT) usage. • It extends the concept of IaaS to the network sector. • It enables the creation of marketplaces of virtual resources “The benefits of virtualization apply equally to carrier networks and enterprise data centers , both of which are undergoing complex consolidation efforts. The most salient benefits include simplification of architecture, consolidation of devices, reduction of operational complexity, and improvement in scale driven by efficient and dynamic partitioning of resources. These advantages play a central role in reducing TCO in both networking and IT environments.” Ref(2008. Yankee Group Research, P. Marshall, M. Bieberich) APAN, 30 th meeting, Hanoi, Vietnam 6 August 2010
GEYSERS and Cloud Computing 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 similar ownership 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 increases in popularity and scale, massive utilisation of network infrastructure will be observed, with single fibres potentially serving 1000's of cloud customers and service providers simultaneously APAN, 30 th meeting, Hanoi, Vietnam 7 August 2010
New Case study.... “Amazon cloud uses FedEx instead of the Internet to ship data” The new Amazon Web Services Import/Export service (Provided by FedEX), which became generally available, is at once a convenient method of easing the pain caused by large data transfers and a recognition that the Internet as it stands today doesn't necessarily provide the unlimited, on-demand scalability that cloud computing providers like to promise. Is it more efficient? Less time consuming? Less expensive?... – Optical networks connecting user premises are needed to improve capacity, reliability and reduce costs.

GEYSERS Actors and Roles GEYSERS roles Current actors Virtual IT Infrastructure infrastructure Operator operator IT (VIO) Service Providers NET Virtual infrastructure Infrastructure operator Provider (VIP) Legacy Telcos & Infrastructure Carriers Physical Provider & Infrastructure Management Provider (PIP) APAN, 30 th meeting, Hanoi, Vietnam 10 August 2010
Rationale • Four pillars for contextualising GEYSERS use cases (RORA): – R esources (net + IT) – O wnership (models) ACTOR – R oles – A ctors ROLE … OWNERSHIP PATTERN RESOURCE APAN, 30 th meeting, Hanoi, Vietnam 11 August 2010
RORA Model Basics • Actor and Role: Actor : An entity taking part in a use case that may or may not interact with other entities that take one or several roles. Role : Names a behaviour of an entity participating in a particular context. • 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. APAN, 30 th meeting, Hanoi, Vietnam 12 August 2010
Roles and Capabilities • Physical Infrastructure Provider ( PIP ) o Owns economical rights over PHY resources • Virtual Infrastructure Provider ( VIP ) o Owns administrative rights for planning virtual infrastructures • Virtual Infrastructure Operator ( VIO ) o Owns administrative rights over virtual infrastructures • User/application/Service provider o Consumes Net+IT unified services (NIPS UNI) as resources APAN, 30 th meeting, Hanoi, Vietnam 13 August 2010
Workflow design process ONGOING WORK APAN, 30 th meeting, Hanoi, Vietnam 14 August 2010
Layers: 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 network service 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 APAN, 30 th meeting, Hanoi, Vietnam 15 August 2010
Layers: Enhanced Network Control Plane I • Enhanced transport network connection paradigms (assisted unicast, restricted anycast, full anycast, scheduled connections) • Virtual infrastructure dynamic re-planning – Enhanced TE in GMPLS/PCE to trigger underlying virtual infrastructure re- planning functionalities • Dynamic provisioning, monitoring and recovery functions – Coordinated recovery escalation among LICL/NCP/[appl. layer] • Backward interoperability with std GMPLS/PCE for connection service provisioning. • 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 APAN, 30 th meeting, Hanoi, Vietnam 16 August 2010
