APAN, 30th meeting, Hanoi, Vietnam 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
  • perators and application providers.
  • Provide an enabler for the integration of dynamic optical network

services in cloud computing scenarios.

  • Architecture definition, design, prototyping and validation

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

Why Infrastructure Virtualisation?

6

  • 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)

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

  • f network infrastructure will be observed,

with single fibres potentially serving 1000's

  • f cloud customers and service providers

simultaneously

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.

Rationale

  • Four pillars for contextualising GEYSERS use cases

(RORA):

– Resources (net + IT) – Ownership (models) – Roles – Actors

RORA Model Basics

  • Actor and Role:
  • Actor: An entity taking part in a use case that may or may not interact with
  • ther 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.

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)

Expected Business impact

  • GEYSERS concepts will allow the development of new actors in the

ICT environment

  • GEYSERS approach will enable telcos to access new markets and

strongly impact new business models

– moving their business towards higher value application layers (IaaS) – E.g. allowing to dynamically 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)

19

SLIDE 20

APAN, 30th meeting, Hanoi, Vietnam August 2010

  • GEYSERS can contribute to the energy efficiency with the

augmented information about “green” metrics:

  • Circulating throughout the routing plane of each domain (enhanced OSPF)
  • Using the PCE+ to add energy-aware constrains to the path computation
  • Leverages on its position of control of both IT & Network resources to

add a control dimension: energy efficiency

– Minimizes the energy consumption metrics along its e2e path – Energy efficiency is not only a matter of optimized network routing, but also the selection of the most efficient IT endpoints

  • ...and due to the dynamic procedures for infrastructure re-planning:
  • GEYSERS Optimizes the release/acquisition of IT and network resources
  • GEYSERS Monitors energy consumption performance markers along with end-

users SLA fulfillment
